If Kodak had been more like Apple

Filed under: academic,HCI and usability,web development — alan @ 8:53 am

Finally Kodak has crumbled; technology and the market changed, but Kodak could not keep up. Lots of memories of those bright yellow and black film spools, and memories in photographs piled in boxes beneath the bed.

But just imagine if Kodak had been more like Apple.

I’m wondering about the fallout from the Kodak collapse. I’m not an investor, nor an employee, or even a supplier, but I have used Kodak products since childhood and I do have 40 years of memories in Kodak’s digital photo cloud. There are talks of Fuji buying up the remains of the photo cloud service, so it maybe that they will re-emerge, but for the time being I can no longer stream my photos to friend’s kTV enabled TV sets when I visit, nor view them online.

Happily, my Kodak kReader has a cache of most of my photos. But, how many I’m not sure, when did I last look at the photos of those childhood holidays or my wedding, will they be in my reader, I’ll check my kPhone as well. I’d hate to think I’d lost the snaps of the seaside holiday when my hat blew into the water; I only half remember it, but every time I look at it I remember being told and re-told the story by my dad.

The kReader is only a few months old. I usually try to put off getting a new one as they are so expensive, but even after a couple of years the software updates put a strain on the old machines.  I had to give up when my three year old model seemed to take about a minute to show each photo. It was annoying as this wasn’t just the new photos, but ones I recall viewing instantly on my first photo-reader more than 30 years ago (I can still remember the excitement as I unwrapped it one Christmas, I was 14 at the time, but now children seem to get their first readers when they are 4). The last straw was when the software updates would no longer work on the old processor and all my newer photos were appearing in strange colours.

Some years ago, I’d tried using a Fuji-viewer, which was much cheaper than the Kodak one. In principle you could download your photo cloud collection in an industry standard format and then import them into the Fuji cloud. However, this lost all the notes and dates on the photos and kept timing out unless I downloaded them in small batches, then I lost track of where I was. Even my brother-in-law, who is usually good at this sort of thing, couldn’t help.

But now I’m glad I’ve got the newest model of kReader as it had 8 times the memory of the old one, so hopefully all of my old photos in its cache. But oh no, just thought, has it only cached the things I’ve looked at since I’ve got it?  If so I’ll have hardly anything. Please, please let the kReader have downloaded all it could.

Suddenly, I remember the days when I laughed a little when my mum was still using her reels of old Apple film and the glossy prints that would need scanning to share on the net (not that she did use the net, she’d pop them in the post!). “I know it is the future”, she used to say, “but I never really trust things I can’t hold”. Now I just wish I’d listened to her.

After the Tech Wave is over

Filed under: academic,HCI and usability — alan @ 10:54 pm

The Second Tiree Tech Wave is over.   Yesterday the last participants left by ferry and plane and after a final few hours tidying, the Rural Centre, which the day before had been a tangle of wire and felt, books and papers, cups and biscuit packets, is now as it had been before.  And as I left, the last boxes under my arm, it was strangely silent with only the memory of voices and laughter in my mind.

So is it as if it had never been?  I there anything left behind?  There are a few sheets of Magic Whiteboard on the walls, that I left so that those visiting the Rural Centre in the coming weeks can see something of what we were doing, and there are used teabags and fish-and-chip boxes in the bin, but few traces.

We trod lightly, like the agriculture of the island, where Corncrake and orchid live alongside sheep and cattle.

Some may have heard me talk about the way design is like a Spaghetti Western. In the beginning of the film Clint Eastwood walks into the town, and at the end walks away.  He does not stay, happily ever after, with a girl on his arm, but leaves almost as if nothing had ever happened.

But while he, like the designer, ultimately leaves, things are not the same.  The Carson brothers who had the town in fear for years lie dead in their ranch at the edge of town, the sharp tang of gunfire still in the air and the buzz of flies slowly growing over the elsewise silent bodies.  The crooked major, who had been in the pocket of the Carson brothers, is strapped over a mule heading across the desert towards Mexico, and not a few wooden rails and water buts need to be repaired.  The job of the designer is not to stay, but to leave, but leave change: intervention more than invention.

But the deepest changes are not those visible in the bullet-pocked saloon door, but in the people.  The drunk who used to sit all day at the bar, has discovered that he is not just a drunk, but he is a man, and the barmaid, who used to stand behind the bar has discovered that she is not just a barmaid, but she is a woman.

This is true of the artefacts we create and leave behind as designers, but much more so of the events, which come and go through our lives.  It is not so much the material traces they leave in the environment, but the changes in ourselves.

I know that, as the plane and ferry left with those last participants, a little of myself left with them, and I know many, probably all, felt a little of themselves left behind on Tiree.  This is partly abut the island itself; indeed I know one participant was already planning a family holiday here and another was looking at Tiree houses for sale on RightMove!  But it was also the intensity of five, sometimes relaxed, sometimes frenetic, days together.

So what did we do?

There was no programme of twenty minute talks, no keynotes or demo, indeed no plan nor schedule at all, unusual in our diary-obsessed, deadline-driven world.

Well, we talked.  Not at a podium with microphone and Powerpoint slides, but while sitting around tables, while walking on the beach, and while standing looking up at Tilly, the community wind turbine, the deep sound of her swinging blades resonating in our bones.  And we continued to talk as the sun fell and the overwhelmingly many stars came out , we talked while eating, while drinking and while playing (not so expertly) darts.

We met people from the island those who came to the open evening on Saturday, or popped in during the days, and some at the Harvest Service on Sunday.  We met Mark who told us about the future plans for Tiree Broadband, Jane at PaperWorks who made everything happen, Fiona and others at the Lodge who provided our meals, and many more. Indeed, many thanks to all those on the island who in various ways helped or made those at TTW feel welcome.

We also wrote.  We wrote on sheets of paper, notes and diagrams, and filled in TAPT forms for Clare who was attempting unpack our experiences of peace and calmness in the hope of designing computer systems that aid rather than assault our solitude.  Three large Magic Whiteboard sheets were entitled “I make because …”, “I make with …”, “I make …” and were filled with comments.  And, in these days of measurable objectives, I know that at least a grant proposal, book chapter and paper were written during the long weekend; and the comments on the whiteboards and experiences of the event will be used to create a methodological reflection of the role of making in research which we’ll put into Interfaces and the TTW web site.

We moved.  Walking, throwing darts, washing dishes, and I think all heavily gesturing with our hands while taking.  And became more aware of those movements during Layda’s warm-up improvisation exercises when we mirrored one another’s movements, before using our bodies in RePlay to investigate issues of creativity and act out the internal architecture of Magnus’ planned digital literature system.

We directly encountered the chill of wind and warmth of sunshine, the cattle and sheep, often on the roads as well as in the fields.  We saw on maps the pattern of settlement on the island and on display boards the wools from different breeds on the island. Some of us went to the local historical centre, An Iodhlann [[ http://www.aniodhlann.org.uk/ ]], to see artefacts, documents and displays of the island in times past, from breadbasket of the west of Scotland to wartime airbase.

We slept.  I in my own bed, some in the Lodge, some in the B&B round the corner, Matjaz and Klem in a camper van and Magnus – brave heart – in a tent amongst the sand dunes.  Occasionally some took a break and dozed in the chairs at the Rural Centre or even nodded off over a good dinner (was that me?).

We showed things we had brought with us, including Magnus’ tangle of wires and circuit boards that almost worked, myself a small pack of FireFly units (enough to play with I hope in a future Tech Wave), Layda’s various pieces she had made in previous tech-arts workshops, Steve’s musical instrument combining Android phone and cardboard foil tube, and Alessio’s impressively modified table lamp.

And we made.  We do after all describe this as a making event!  Helen and Claire explored the limits of ZigBee wireless signals.  Several people contributed to an audio experience using proximity sensors and Arduino boards, and Steve’s CogWork Chip: Lego and electronics, maybe the world’s first mechanical random-signal generator.  Descriptions of many of these and other aspects of the event will appear in due course on the TTW site and participants’ blogs.


But it was a remark that Graham made as he was waiting in the ferry queue that is most telling.  It was not the doing that was central, the making, even the talking, but the fact that he didn’t have to do anything at all.  It was the lack of a plan that made space to fill with doing, or not to do so.

Is that the heart?  We need time and space for non-doing, or maybe even un-doing, unwinding tangles of self as well as wire.

There will be another Tiree Tech Wave in March/April, do come to share in some more not doing then.

Who was there:

  • Alessio Malizia – across the seas from Madrid, blurring the boundaries between information, light and space
  • Helen  Pritchard – artist, student of innovation and interested in cows
  • Claire  Andrews – roller girl and researching the design of assistive products

book: The Unfolding of Language, Deutscher

Filed under: academic,books,HCI and usability — alan @ 8:43 am

I have previously read Guy Deutscher‘s “Through the Language Glass“, and have now, topsy turvy, read his earlier book “The Unfolding of Language“.  Both are about language, “The Unfolding of Language” about the development of the complexity of language that we see today from simpler origins, and “Through the Language Glass” about the interaction between language and thought.  Both are full of sometimes witty and always fascinating examples drawn from languages around the world, from the Matses in the Amazon to Ancient Sumarian.

I recall my own interest in the origins of language began young, as a seven year old over breakfast one day, asking whether ‘night, was a contraction of ‘no light’.  While this was an etymological red herring, it is very much the kind of change that Deutscher documents in detail showing the way a word accretes beginnings and ending through juxtaposition of simpler words followed by erosion of hard to pronounce sounds.

One of my favourites examples was the French “aujourd’hui”.  The word ‘hui, was Old French for ‘today’, but was originally Latin “hoc die”, “(on) this day”. Because ‘hui’ is not very emphatic it became “au jour d’hui”, “on the day of this day” , which contracted to the current ‘aujourd’hui’. Except now to add emphasis some French speakers are starting to say “au jour aujourd’hui”, “on the day on the day of this day”!  This reminds me of Longsleddale in the Lake District (inspiration for Postman Pat‘s Greendale),  a contraction of “long sled dale”, which literally means “long valley valley” from Old English “slaed” meaning “valley” … although I once even saw something suggesting that ‘long’ itself in the name was also “valley” in a different language!

Deutscher gives many more prosaic examples where words meaning ‘I’, ‘you’, ‘she’ get accreted to verbs to create the verb endings found in languages such as French, and how prepositions (themselves metaphorically derived from words like ‘back’) were merged with nouns to create the complex case endings of Latin.

However, the most complex edifice, which Deutscher returns to repeatedly, is that of the Semitic languages with a template system of vowels around three-consonant roots, where the vowel templates change the meaning of the root.  To illustrate he uses the (fictional!) root ‘sng’ meaning ‘to snog’ and discusses how first simple templates such as ‘snug’ (“I snogged”) and then more complex constructions such as ‘hitsunnag’ (“he was made to snog himself”) all arose from simple processes of combination, shortening and generalisation.

“The Unfolding of Language” begins with the 19th century observation that all languages seem to be in a process of degeneration where more complex  forms such as the Latin case system or early English verb endings are progressively simplified and reduced. The linguists of the day saw all languages in a state of continuous decay from an early linguistic Golden Age. Indeed one linguist, August Schleicher, suggested that there was a process where language develops until it is complex enough to get things done, and only then recorded history starts, after which the effort spent on language is instead spent in making history.

As with geology, or biological evolution, the modern linguist rejects this staged view of the past, looking towards the Law of Uniformitarianism, things are as they have always been, so one can work out what must have happened in the pre-recorded past by what is happening now.  However, whilst generally finding this convincing, throughout the book I had a niggling feeling that there is a difference.  By definition, those languages for which we have written records are those of large developed civilisations, who moreover are based on writing. Furthermore I am aware that for biological evolution small isolated groups (e.g. on islands or cut off in valleys) are particularly important for introducing novelty into larger populations, and I assume the same would be true of languages, but somewhat stultified by mass communication.

Deutscher does deal with this briefly, but right at the very end in a short epilogue.  I feel there is a whole additional story about the interaction between culture and the grammatical development of language.  I recall in school a teacher explained how in Latin the feminine words tended to belong to the early period linked to agriculture and the land, masculine words for later interests in war and conquest, and neuter for the still later phase of civic and political development. There were many exceptions, but even this modicum of order helped me to make sense of what otherwise seemed an arbitrary distinction.

The epilogue also mentions that the sole exception to the ‘decline’ in linguistic complexity is Arabic with its complex template system, still preserved today.

While reading the chapters about the three letter roots, I was struck by the fact that both Hebrew an Arabic are written as consonants only with vowels interpolated by diacritical marks or simply remembered convention (although Deutscher does not mention this himself). I had always assumed that this was like English where t’s pssble t rd txt wth n vwls t ll. However, the vowels are far more critical for Semitic languages where the vowel-less words could make the difference between “he did it” and “it will be done to him”.  Did this difference in writing stem from the root+template system, or vice versa, or maybe they simply mutually reinforced each other?

The other factor regarding Arabic’s remarkable complexity must surely be the Quran. Whereas the Bible was read for a over a millennium in Latin, a non-spoken language, and later translated focused on the meaning; in contrast there is a great emphasis on the precise form of the Quran together with continuous lengthy recitation.  As the King James Bible has been argued to have been a significant influence on modern English since the 17th century, it seems likely the Quran has been a factor in preserving Arabic for the last 1500 years.

Early in “The Unfolding of Language” Deutscher dismisses attempts to look at the even earlier prehistoric roots of language as there is no direct evidence. I assume that this would include Mithin’s “The Singing Neanderthals“, which I posted about recently. There is of course a lot of truth in this criticism; certainly Mithin’s account included a lot of guesswork, albeit founded on paleontological evidence.  However, Deutscher’s own arguments include extrapolating to recent prehistory. These extrapolations are based on early written languages and subsequent recorded developments, but also include guesswork between the hard evidence, as does the whole family-tree of languages.  Deutscher was originally a Cambridge mathematician, like me, so, perhaps unsurprisingly, I found his style of argument convincing. However, given the foundations on Uniformitarianism, which, as noted above, is at best partial when moving from history to pre-history, there seems more of  a continuum rather than sharp distinction between the levels of interpretation and extrapolation in this book and Mithin’s.

Deutscher’s account seeks to fill in the gap between the deep prehistoric origins of protolanguage (what Deutscher’s calls ‘me Tarzan’ language) and its subsequent development in the era of media-society (starting 5000BC with extensive Sumerian writing). Rather than seeing these separately, I feel there is a rich account building across various authors, which will, in time, yield a more complete view of our current language and its past.

book: The Singing Neanderthals, Mithin

Filed under: academic,books,HCI and usability — alan @ 10:25 pm

One of my birthday presents was Steven Mithin’s “The Singing Neanderthals” and, having been on holiday, I have already read it! I read Mithin’s “The Prehistory of the Mind” some years ago and have referred to it repeatedly over the years1, so was excited to receive this book, and it has not disappointed. I like his broad approach taking evidence from a variety of sources, as well as his own discipline of prehistory; in times when everyone claims to be cross-disciplinary, Mithin truly is.

“The Singing Neanderthal”, as its title suggests, is about the role of music in the evolutionary development of the modern human. We all seem to be born with an element of music in our heart, and Mithin seeks to understand why this is so, and how music is related to, and part of the development of, language. Mithin argues that elements of music developed in various later hominids as a form of primitive communication2, but separated from language in homo sapiens when music became specialised to the communication of emotion and language to more precise actions and concepts.

The book ‘explains’ various known musical facts, including the universality of music across cultures and the fact that most of us do not have perfect pitch … even though young babies do (p77). The hard facts of how things were for humans or related species tens or hundreds of thousands of years ago are sparse, so there is inevitably an element of speculation in Mithin’s theories, but he shows how many, otherwise disparate pieces of evidence from palaeontology, psychology and musicology make sense given the centrality of music.

Whether or not you accept Mithin’s thesis, the first part of the book provides a wide ranging review of current knowledge about the human psychology of music. Coincidentally, while reading the book, there was an article in the Independent reporting on evidence for the importance of music therapy in dealing with depression and aiding the rehabilitation of stroke victims3, reinforcing messages from Mithin’s review.

The topic of “The Singing Neanderthal” is particularly close to my own heart as my first personal forays into evolutionary psychology (long before I knew the term, or discovered Cosmides and Tooby’s work), was in attempting to make sense of human limits to delays and rhythm.

Those who have been to my lectures on time since the mid 1990s will recall being asked to first clap in time and then swing their legs ever faster … sometimes until they fall over! The reason for this is to demonstrate the fact that we cannot keep beats much slower than one per second4, and then explain this in terms of our need for a mental ‘beat keeper’ for walking and running. The leg shaking is to show how our legs, as a simple pendulum, have a natural frequency of around 1Hz, hence determining our slowest walk and hence need for rhythm.

Mithin likewise points to walking and running as crucial in the development of rhythm, in particular the additional demands of bipedal motion (p150). Rhythm, he argues, is not just about music, but also a shared skill needed for turn-taking in conversation (p17), and for emotional bonding.

In just the last few weeks, at the HCI conference in Newcastle, I learnt that entrainment, when we keep time with others, is a rare skill amongst animals, almost uniquely human. Mithin also notes this (p206), with exceptions, in particular one species of frog, where the males gather in groups to sing/croak in synchrony. One suggested reason for this is that the louder sound can attract females from a larger distance. This cooperative behaviour of course acts against each frog’s own interest to ‘get the girl’ so they also seek to out-perform each other when a female frog arrives. Mithin imagines that similar pressures may have sparked early hominid music making. As well as the fact that synchrony makes the frogs louder and so easy to hear, I wonder whether the discerning female frogs also realise that if they go to a frog choir they get to chose amongst them, whereas if they follow a single frog croak they get stuck with the frog they find; a form of frog speed dating?

Mithin also suggests that the human ability to synchronise rhythm is about ‘boundary loss’ seeing oneself less as an individual and more as part of a group, important for early humans about to engage in risky collaborative hunting expeditions. He cites evidence of this from the psychology of music, anthropology, and it is part of many people’s personal experience, for example, in a football crowd, or Last Night at the Proms.

This reminds me of the experiments where a rubber hand is touched in time with touching a person’s real hand; after a while the subject starts to feel as if the rubber hand is his or her own hand. Effectively our brain assumes that this thing that correlates with feeling must be part of oneself5. Maybe a similar thing happens in choral singing, I voluntarily make a sound and simultaneously everyone makes the sound, so it is as if the whole choir is an extension of my own body?

Part of the neurological evidence for the importance of group music making concerns the production of oxytocin. In experiments on female prairie voles that have had oxytocin production inhibited, they engage in sex as freely as normal voles, but fail to pair bond (p217). The implication is that oxytocin’s role in bonding applies equally to social groups. While this explains a mechanism by which collaborative rhythmic activities create ‘boundary loss’, it doesn’t explain why oxytocin is created through rhythmic activity in the first place. I wonder if this is perhaps to do with bipedalism and the need for synchronised movement during face-to-face copulation, which would explain why humans can do synchronised rhythms whereas apes cannot. That is, rhythmic movement and oxytocin production become associated for sexual reasons and then this generalises to the social domain. Think again of that chanting football crowd?

I should note that Mithin also discusses at length the use of music in bonding with infants, as anyone who has sung to a baby knows, so this offers an alternative route to rhythm & bonding … but not one that is particular to humans, so I will stick with my hypothesis ;-)

Sexual selection is a strong theme in the book, the kind of runaway selection that leads to the peacock tail. Changing lifestyles of early humans, in particular longer periods looking after immature young, led to a greater degree of female control in the selection of partners. As human size came close to the physical limits of the environment (p185), Mithin suggests that other qualities had to be used by females to choose their mate, notably male singing and dance – prehistoric Saturday Night Fever.

As one evidence for female mate choice, Mithin points to the overly symmetric nature of hand axes and imagines hopeful males demonstrating their dexterity by knapping ever more perfect axes in front of admiring females (p188). However, this brings to mind Calvin’s “Ascent of Mind“, which argues that these symmetric, ovoid axes were used like a discus, thrown into the midst of a herd of prey to bring one down. The two theories for axe shape are not incompatible. Calvin suggests that the complex physical coordination required by axe throwing would have driven general brain development. In fact these forms of coordination, are not so far from those needed for musical movement, and indeed expert flint knapping, so maybe it was this skills that were demonstrated by the shaping of axes beyond that immediately necessary for purpose.

Mithin’s description of the musical nature of mother-child interactions also brought to mind Broomhall’s “Eternal Child“. Broomhall ‘s central thesis is that humans are effectively in a sort of arrested development with many features, not least our near nakedness, characteristic of infants. Although it was not one of the points Broomhall makes, his arguments made sense to me in terms of the mental flexibility that characterises childhood, and the way this is necessary for advanced human innovation; I am always encouraging students to think in a more childlike way. If Broomhall’s theories were correct, then this would help explain how some of the music making more characteristic of mother-infant interactions become generalised to adult social interactions.

I do notice an element of mutual debunking amongst those writing about richer cognitive aspects of early human and hominid development. I guess a common trait in disciplines when evidence is thin, and theories have to fill a lot of blanks. So maybe Mithin, Calvin and Broomhall would not welcome me bringing their respective contributions together! However, as in other areas where data is necessarily scant (such as sub-atomic physics), one does feel a developing level of methodological rigour, and the fact that these quite different theoretical approaches have points of connection, does suggest that a deeper understanding of early human cognition, while not yet definitive, is developing.

In summary, and as part of this wider unfolding story, “The Singing Neanderthal” is an engaging and entertaining book to read whether you are interested in the psychological and social impact of music itself, or the development of the human mind.

… and I have another of Mithin’s books in the birthday pile, so looking forward to that too!

hyperreal tactile iPad keyboard

Filed under: HCI and usability,web development — alan @ 7:52 pm

The soft keyboards on iPhone and iPad are surprisingly good.  On the iPad I am finding my 3 finger typing almost as fast as on a physical keyboard … although a little more error prone as I keep mis-hitting the space bar and getting ‘n’ or ‘b’ instead (as inmthis shortbphrasemi am typing now), which the poor spell corrector can’t manage at all.

Of course if ou are a touch typist things may be different.

I was especially struck by the image of the keyboard on the iPad, which on the ‘F’ and ‘J’ keys has an image of the tiny tactile bar that allows easy finger positioning by touch alone.  However, this is of course a flat screen and I am feeling I am in some sort of surreal world.

announcing Tiree Tech Wave!

Filed under: academic,HCI and usability,web development — alan @ 8:56 pm

Ever since I came to Tiree I’ve had a vision of bringing people here, to share some of the atmosphere and work together.  A few of you have come on research visits and we have had some really productive times.  Others have said they wished they could come sometime.

Well now is your chance …

Come to Tiree Tech Wave in March to make, talk and play at the wind-ripping edge of digital technology.

seascape

Every year Tiree hosts the Wave Classic, a key international wind surfing event.  Those of us at the edge of the digital wave do not risk cold seas and bodily injury, but there is something of the same thrill as we explore the limits of code, circuit boards and social computation.

iconsThe cutting edge of wind-surfing boards is now high technology, but typically made by artisan craftsfolk, themselves often surfers.  Similarly hardware platforms such as Arduino, mobile apps for iPhone and Android, and web mashups enabled by public APIs and linked data are all enabling a new maker culture, challenging the hegemony of global corporations.

artworkThe Western Celtic fringes were one of the oases of knowledge and learning during the ‘dark ages’.  There is something about the empty horizon that helped the hermit to focus on God and inspired a flowering of decorative book-making, even in the face of battering storms of winter and Viking attacks of summer; a starkness that gave scholars time to think in peace between danger-fraught travel to other centres of learning across Europe.

Nowadays regular Flybe flights and Calmac ferries reduce the risk of Viking attacks whilst travelling to the isles, broadband Internet and satellite TV invade the hermit cell, and double glazing and central heating mollify the elements.  Yet there is still a rawness that helps focus the mind, a slightly more tenuous connection to the global infrastructure that fosters a spirit of self-reliance and independence.

LEDsOver a long weekend 17 – 21 March (TBC), we plan what I hope will be a semi-regular event.  A time to step out, albeit momentarily, from a target-driven world, to experiment and play with hardware and software, to discuss the issues of our new digital maker culture, what we know and what we seek to understand, and above all to make things together.

This is all about technology and people: the physical device that sits in our hands, the data.gov.uk mashup that tells us about local crime, the new challenges to personal privacy and society and the nation state.

Bring your soldering iron, and Arduino boards, your laptop and API specs, your half-written theses and semi-formed ideas, your favourite book or even well-loved eReader (!).  The format will be informal, with lots of time to work hands-on together; however, there will be the opportunity for short talks/demos/how-to-do-it sessions.  Also, if there is demand, I’d  be happy to do some more semi-formal tutorial sessions and maybe others would too (Arduino making, linked data).

Currently we have no idea whether there will be three or three hundred people interested, but aiming for something like 15 – 30 participants.  We’ll keep costs down, probably around £70 for meeting rooms, lunches, etc. over the five days, but will confirm that and more details shortly.

Follow on Twitter at @tireetechwave and the website will be at tireetechwave.com. However, it is still ‘under development’, so don’t be surprised at the odd glich over the next couple of weeks as we sort out details.

If you are interested in coming or want to know more mail me or Graham Dean

Struggling with Heidegger

Filed under: academic,HCI and usability — alan @ 9:26 am

Heidegger and hammers have been part of HCI’s conceptualisation from pretty much as long as I can recall.  Although maybe I first heard the words at some sort of day workshop in the late 1980s as the hammer example as used in HCI annoyed me even then, so let’s start with hammers.

hammers

I should explain that problems with the hammer example are not my current struggles with Heidegger!  For the hammer it is just that Heidegger’s ‘ready at hand’ is often confused with ‘walk up and use’.  In  Heidegger ready-at-hand refers to the way one is focused on the nail, or wood to be joined, not the hammer itself:

“The work to be produced is the “towards which” of such things as the hammer, the plane, and the needle” (Being and Time1, p.70/99)

To be ‘ready to hand’ like this typically requires familiarity with the equipment (another big Heidegger word!), and is very different from the way a cash machine or tourist information systems should be in some ways accessible independent of prior knowledge (or at least only generic knowledge and skills).

My especial annoyance with the hammer example stems from the fact that my father was a carpenter and I reckon it took me around 10 years to learn how to use a hammer properly2!  Even holding it properly is not obvious, look at the picture.

There is a hand sized depression in the middle.  If you have read Norman’s POET you will think, “ah yes perceptual affordance’, and grasp it like this:

But no that is not the way to hold it!  If try to use it like this you end up using the strength of your arm to knock in the nail and not the weight of the hammer.

Give it to a child, surely the ultimate test of ‘walk up and use’, and they often grasp the head like this.

In fact this is quite sensible for a child as a ‘proper’ grip would put too much strain on their wrist.  Recall  Gibson’s definition of affordance was relational3, about the ecological fit between the object and the potential actions, and the actions depends on who is doing the acting.  For a small child with weaker arms the hammer probably only affords use at all with this grip.

In fact the ‘proper’ grip is to hold it quite near the end where you can use the maximum swing of the hammer to make most use of the weight of the hammer and its angular momentum:

Anyway, I think maybe Heidegger knew this even if many who quote him don’t!

Heidegger

OK, so its alright me complaining about other people mis-using Heidegger, but I am in the middle of writing one of the chapters for TouchIT and so need to make sure I don’t get it wrong myself … and there my struggles begin.  I need to write about ready-to-hand and present-to-hand.   I thought I understood them, but always it has been from secondary sources and as I sat with Being and Time in one hand, my Oxford Companion to Philosophy in another and various other books in my teeth … I began to doubt.

First of all what I thought the distinction was:

  • ready at hand — when you are using the tool and it is invisible to you, you just focus on the work to be done with it
  • present at hand — when there is some sort of breakdown, the hammer head is loose or you don’t have the right tool to hand and so start to focus on the tools themsleves rather than on the job at hand

Scanning the internet this is certainly what others think, for example blog posts at 251 philosophy and Matt Webb at Berg4.  Koschmann, Kuutti and Hickman produced an excellent comparison of breakdown in Heidegger, Leont’ev and Dewey5, and from this it looks as though the above distinction maybe comes Dreyfus summary of Heidegger — but again I don’t have a copy of Dreyfus’ “Being-in-the-World“, so not certain.

Now this is an important distinction, and one that Heidegger certainly makes.  The first part is very clearly what Heidegger means by ready-to-hand:

“The peculiarity of what is proximally to hand is that, in its readiness-to-hand, it must, as it were, withdraw … that with which we concern ourselves primarily is the work …” (B&T, p.69/99)

The second point Heidegger also makes at length distinguishing at least three kinds of breakdown situation.  It just seems a lot less clear whether ‘present-at-hand’ is really the right term for it.  Certainly the ‘present-at-hand’ quality of an artefact becomes foregrounded during breakdown:

“Pure presence at hand announces itself in such equipment, but only to withdraw to the readiness-in-hand with which one concerns oneself — that is to say, of the sort of thing we find when we put it back into repair.” (B&T, p.73/103)

But the preceeding sentance says

“it shows itself as an equipmental Thing which looks so and so, and which, in its readiness-to-hand as looking that way, has constantly been present-at-hand too.” (B&T, p.73/103)

That is present-at-hand is not so much in contrast to ready-at-hand, but in a sense ‘there all along’; the difference is that during breakdown the presence-at-hand becomes foregrounded. Indeed when ‘present-at-hand’ is first introduced Heidegger appears to be using it as a binary distinction between Dasein, (human) entities that exist and ponder their existence, and other entities such as a table, rock or tree (p. 42/67).  The contrast is not so much between ready-to-hand and present-to-hand, but between ready-to-hand and ‘just present-at-hand’ (p.71/101) or ‘Being-just-present-at-hand-and-no-more’ (p.73/103). For Heidegger to seems not so much that ‘ready-to-hand’ stands in in opposition to ‘present-to-hand’; it is just more significant.

To put this in context, traditional philosophy had focused exclusively on the more categorically defined aspects of things as they are in the world (‘existentia’/present-at-hand), whilst ignoring the primary way they are encountered by us (Dasein, real knowing existence) as ready-to-hand, invisible in their purposefulness.  Heidegger seeks to redress this.

“If we look at Things just ‘theoretically’, we can get along without understanding readiness-to-hand.” (B&T p.69/98)

Heidegger wants to avoid the speculation of previous science and philosophy. Although it is not a Heidegger word, I use ‘speculation’ here with all of its connotations, pondering at a distance, but without commitment, or like spectators at a sports stadium looking in at something distant and other.  In contrast, ready-to-hand suggests commitment, being actively ‘in the world’ and even when Heidegger talks about those moments when an entity ceases to be ready-to-hand and is seen as present-to-hand, he uses the term circumspection — a casting of the eye around, so that the Dasein, the person, is in the centre.

So present-at-hand is simply the mode of being of the entities that are not Dasein (aware of their own existence), but our primary mode of experience of them and thus in a sense the essence of their real existence is when they are ready-to-hand.  I note Roderick Munday’s useful “Glossary of Terms in Being and Time” highlights just this broader sense of present-at-hand.

Maybe the confusion arises because Heidegger’s concern is phenomenological and so when an artefact is ready-to-hand and its presence-to-hand ‘withdraws’, in a sense it is no longer present-to-hand as this is no longer a phenomenon; and yet he also seems to hold a foot in realism and so in another sense it is still present-to-hand.  In discussing this tension between realism and idealism in Heidegger, Stepanich6 distinguishes present-at-hand and ready-to-hand, from presence-to-hand and readiness-to-hand — however no-one else does this so maybe that is a little too subtle!

To end this section (almost) with Heidegger’s words, a key statement, often quoted, seems to say precisely what I have argued above, or maybe precisely the opposite:

“Yet only by reason of something present-at-hand ‘is there’ anything ready-to-hand.  Does it follow, however, granting this thesis for the nonce, that readiness-to-hand is ontologically founded upon presence-at-hand?” (B&T, p.71/101)

What sort of philosopher makes a key point through a rhetorical question?

So, for TouchIT, maybe my safest course is to follow the example of the Oxford Companion to Philosophy, which describes ready-to-hand, but circumspectly never mentions present-to-hand at all?

and anyway what’s wrong with …

On a last note there is another confusion, or maybe mistaken attitude, that seems to be common when referring to ready-to-hand.  Heidegger’s concern was in ontology, understanding the nature of being, and so he asserted the ontological primacy of the ready-to-hand, especially in light of the previous dominant concerns of philosophy.  However, in HCI, where we are interested not in the philosophical question, but the pragmatic one of utility, usability, and experience, Heidegger is often misapplied as a kind of fetishism of engagement, as if everything should be ready-to-hand all the time.

Of course for many purposes this is correct, as I type I do not want to be aware of the keys I press, not even of the pages of the book that I turn.

Yet there is also a merit in breaking this engagement, to encourage reflection and indeed the circumspection that Heidegger discusses.  Indeed Gaver et al.’s focus on ambiguity in design7 is often just to encourage that reflection and questioning, bringing things to the foreground that were once background.

Furthermore as HCI practitioners and academics we need to both take seriously the ready-to-hand-ness of effective design, but also (just as Heidegger is doing) actually look at the ready-to-hand-ness of things seeing them and their use not taking them for granted.  I constantly strive to find ways to become aware of the mundane, and offer students tools for estrangement to look at the world askance8.

“To lay bare what is  just present-at-hand and no more, cognition must first penetrate beyond what is ready-to-hand in our concern.” (B&T, p.71/101)

This ability to step out and be aware of what we are doing is precisely the quality that Schon recognises as being critical for the ‘Reflective Practioner‘.  Indeed, my practical advice on using the hammer in the footnotes below comes precisely through reflection on hammering, and breakdowns in hammering, not through the times when the hammer was ready-to-hand..

Heidegger is indeed right that our primary existence is being in the world, not abstractly viewing it from afar.  And yet, sometimes also, just as Heidegger himself did as he pondered and wrote about these issues, one of our crowning glories as human beings is precisely that we are able also in a sense to step outside ourselves and look in wonder.

In common with much of the literature the page references to Being and Time are all of the form p.70/99 where the first number refers to the page numbers in the original German (which I have not read!) and the second number to the page in Macquarrie and Robinson’s translation of Being and Time published by Blackwell.

  2. Practical hammering – a few tips: The key thing is to focus on making sure the face of the hammer is perpendicular to the nail, if there is a slight angle the nail will bend.  For thin oval wire nails, if one does bend do not knock the nail back upright, most likely it will simply bend again and just snap.  Instead, simply hit the head of the nail while still bent, but keeping the hammer face perpendicular to the nail not the hole.  So long as the nail has cut any depth of hole it will simply follow its own path and straighten of its own accord.

bookshelf in Rome

Filed under: academic,books,personal — alan @ 5:59 pm

I posted a few weeks ago about books I had got to bring to Rome.  Since then I got another small collection because I had done some reviewing for Routledge.

Mostly philosophy of the mind and materiality … the latter to help as we work on the DEPtH book on Physicality, TouchIT

In fact, with these and the previous  set I had far too many even for a month of evenings, and below you can see the books I actually brought.

As well as a selection from the academic books also some fiction/leisure reading, some old favourites and some new ones:

  • How Green was My Valley, Richard Llewellyn – a Welshman has to read this :-/
  • The Catcher in the Rye, J.D. Salinger – a classic I’ve never read
  • More of the Good Life – the TV series was formative for me as a child, but 40 seemed so far away
  • Lark Rise to Candleford, Flora Thompson – some years since I’ve read it last, and have been loving the TV series, but I don’t think it has stayed very close to the book!
  • Nella Last’s War – this is the book that was the basis for the TV drama Housewife 49 and part of the Mass Observation that collected diaries from ordinary people across Britain during the Second World War.
  • Ruth, Elizabeth Gaskill – another classic that I’ve not read yet!
  • As I Walked Out One Midsummer Morning.  Laurie Lee’s account of travelling in Spain in the run up to the Civel War.  I read it in school for O’level.
  • Swallowdale, Arthur Ransome – Couldn’t find Swallow’s an Amazons, I think one of the girls might have it on their shelves!
  • The Shining Company, Rosemary Sutcliff – we have loads of her histroical novels for children.  I find that good children’s writing is so much better than most adult books, which often feel they need to be incomprehensible to be good.
  • The Growing Summer, Noel Streatfield – lovely story, children visiting a quirky old lady in west coast of Ireland.
  • Hovel in the Hills, Elizabeth West  – another book I’ve read many times, but not for many years.  True story about a couple who buy an old house on a Welsh hillside.

In addition, but missing from the picture, is one I borrowed from my daughter, Tamara Pierce’s  The Healing in the Vine, and one I’ve borrowed from Tiziana Catarci during my visit the Languages of Art.

So, two weeks in and how far have I got …

Well, been a little busy, two journal papers, a book chapter, an interfaces article, two 3 hour lectures to the masters students here, a seminar, reading thesis chapters and helping with two grant proposals … so not got very far through the bookshelf.

In fact, to be brutally honest, so far only finished the Tamora Pierce and nearly finished Gibson (just conclusions to go):

As you can see LOTS of notes on Gibson, I will write a very long blog sometime about this, but several others in line first!

But next week several train journeys, so may get through a few more books :-)

Touching Technology

Filed under: academic,HCI and usability — alan @ 7:16 pm

I’ve given a number of talks over recent months on aspects of physicality, twice during winter schools in Switzerland and India that I blogged about (From Anzere in the Alps to the Taj Bangelore in two weeks) a month or so back, and twice during my visit to Athens and Tripolis a few weeks ago.

I have finished writing up the notes of the talks as “Touching Technology: taking the physical world seriously in digital design“.  The notes  are partly a summary of material presented in previous papers and also some new material.  Here is the abstract:

Although we live in an increasingly digital world, our bodies and minds are designed to interact with the physical. When designing purely physical artefacts we do not need to understand how their physicality makes them work – they simply have it. However, as we design hybrid physical/digital products, we must now understand what we lose or confuse by the added digitality. With two and half millennia of philosophical ponderings since Plato and Aristotle, several hundred years of modern science, and perhaps one hundred and fifty years of near modern engineering – surely we know sufficient about the physical for ordinary product design? While this may be true of the physical properties themselves, it is not the fact for the way people interact with and rely on those properties. It is only when the nature of physicality is perturbed by the unusual and, in particular the digital, that it becomes clear what is and is not central to our understanding of the world. This talk discusses some of the obvious and not so obvious properties that make physical objects different from digital ones. We see how we can model the physical aspects of devices and how these interact with digital functionality.

After finishing typing up the notes I realised I have become worryingly scholarly – 59 references and it is just notes of the talk!

bookshelf

Filed under: academic,books,personal — alan @ 7:04 pm

Got some books to fill my evenings when I’m in Rome during May, mostly about physicality and relating to DEPtH project.

Several classics about the nature of action in the physical world:

  • James Gibson,. The Ecological Approach to Visual Perception. New Jersey, USA, Lawrence Erlbaum Associates, 1979
    Actually a bit embarrassing as I have written about affordance and cited Gibson many times, but never read the original!
  • Martin Heidegger.  Being and Time. Harper Perennial Modern Classics; Reprint edition, 2008
    Similarly how many times have I cited ‘ready to hand’!  But then again how many people have read Heidegger?
  • Martin Heidegger.  Basic Writings. Harper Perennial Modern Classics, 2008
    This is a ‘best bits’ for Heidegger!
  • Maurice Merleau-Ponty.  Phenomenology of Perception. London, England, Routledge, 1958
    Everybody seems to cite Merleau-Ponty, but don’t know much about him … except all that French philosophy is bound to be heavy!

A couple more with a human as action system perspective, that seem to be well reviewed (and I’m guessing easier reads!):

Finally three about memories: linking generally to memories for life and also designing for reflection, but looking at them more specifically in relation to Haliyana‘s photologing studies.

  • Paul Ricoeur.  Memory, History, Forgetting. Chicago University Press; New edition,  2006
  • Paul Ricoeur.  Time and Narrative, Volume 1, Chicago University Press; New edition,  1990
    More classics … and I suspect heavy reads, got another Rocoeur already, but it is still on my “to read” pile.
  • Svetlana Boym.  The Future of Nostalgia. Basic Books, 2008
    Just sounded good.

Will report on them as I go :-)
