mirrors and estrangement

One of my PhD students, Fariza, has been extensively studying a single person, a women not so disimilar from herself. In doing so they have become friends and much of Fariza’s thesis (soon to be submitted) concerns the methodological issues surrounding this.

pianoOne issue we have discussed at length is the importance of estrangement, that distancing oneself from the commonplace to make the taken for granted become apparent. We do not see the things closest to us: the dirty toenail, the crumpled sheet, the asymmetric fall of the piano music stand, the things lost because they are in the open.

Artists and comedians often open our eyes to the unseen-because-unnoticed aspects of life, such as Emin’s own crumpled sheets or the poignant woman on the platform in “The Fall and Rise of Reggie Perrin”1. Garfinkel’s breaching experiments attempt to bring this incisive comic eye to social science. Of novelists Gabriel Garcí­a Márquez is the master of this; through his true to life yet surreal accounts, with sometimes tenderness and sometimes almost cruel dispassion, he describes in intricate detail the intimate yet insignificant.

The Last Battle, C.S. LewisBerger talks about the way artists look at their work in a mirror to see it afresh and he himself sees the sunshine of lilacs in the mirror, lilacs that show him only their shadows2. I was reminded of one of C.S. Lewis’ Narnia books where the supra-reality of the mirror image is more crystal sharp, more ‘real’ than the ordinary world3.

Mirrors bring to mind reflective practice, just as Fariza has to write herself into her own accounts, the mirror often shows not only the unseen side of an object but also oneself and oneself in relation to the object. The seer and seen are themselves seen and, like Berger’s lilacs, the partiality of one’s seeing becomes more obvious. The mirror is not so much important because it shows the hidden sun-glowed lilacs, but because it says that the shadowed petals are not the whole flower.

Arnolfini Mariage: mirror closeupI am reminded of that Dutch painting by van Eyck where the apparently pregnant woman and her husband stand in their home with their lap dog between them and discarded outdoor shoes untidily dropped4. On the wall behind the couple is a convex mirror capturing the whole scene from behind, and in the reflected doorway where you stand is the tiny image of van Eyck and another. Unlike supposedly ‘good’ scientific writing in incomprehensible passive speech, the artist has not painted himself out of his picture.

Arnolfini Mariage: dog closeupBerger also talks about paintings being painted for the moment of seeing, yet so many portraits do not look towards you, or even the artist, but through you, beyond you, to an unseen landscape. This may be because it is hard to paint eyes, or because it is hard to stare into the eyes of one’s painter. In life it is only with the deepest lovers or friends that we dare to share like this, hence perhaps the growing friendship that Fariza experienced when gazing deeply together into her subject’s life. Also, perhaps why the most intimate paintings have often been of the painter’s wives or lovers. Unusually in van Eyck’s painting, clearly of close friends, the couple do not gaze either aloof or uncaring past the viewer, but instead gaze within the painting demurely to one another … it is only the small dog that stares back.

Mona LisaThis may be part of the Mona Lisa’s allure. I have never seen it ‘in the flesh’, but everyone talks about the eyes that they follow you. However, look again, it is not so much that they follow you, but, unusual amongst paintings, they actually look at you and I suppose at Leonardo himself.

I know Fariza has found this, and I am sure it is universal, that if we look closely and honestly at those around us, we begin more clearly to see ourselves .

What is Computing? The centrality of systemics

Recently I was in a meeting where the issue of ‘core’ computer science came up. One person listed a few areas, but then this was challenged by another member of the group who said (to be fair, partly in jest), that core computer science should certainly include computer architecture, but not the ‘human stuff’.

I felt a little like a teenager complete with T-shirt and iPod dropped into Jurassic Park arguments that I thought had been put to bed in the 1980s suddenly resurfacing – how do you explain this white thing that makes sounds from its earphones to a caveman wearing skins?

However, I also felt a certain sympathy as I often wonder about computer science as a whole; indeed it has its own arguments in the 1960s and ’70s as to whether it was a ‘discipline’ as opposed to just an application domain for maths or electronics, or just a tool for business. Maybe one of the clinchers was the theoretical foundations of computing in the work of Church and Turing … but strangely enough at Lancaster the closest to this, the course on algorithmic complexity, is taught by a HCI person!

One of my worries in computing is that these theoretical foundations are still weak, there is black hole in the theoretical centre of computer science1. However, these theoretical issues were certainly not what was bothering my colleague. To answer his challenge and my own worries about the discipline we really need to know – what is computing?

  1. This demands a discussion of its own, but the basic problem is that while Church and Turing gave us understanding of disembodied computation, we still do not have clear understanding of generic computation when embodied in devices in general only particular architectures. [back]

HCI and CSCW – is your usability too small

Recently heard some group feedback on our HCI textbook. Nearly all said that they did NOT want any CSCW. I was appalled as considering any sort of user interaction without its surrounding social and organisational settings seems as fundamentally misbegotten as considering a system without its users.

Has the usability world gone mad or is it just that our conception of HCI has become too narrow?

robot friends

Last night we watched Jurassic Park 3 and today found you can have a little dinosaur all of your own!

Pleo Dinosaur Sony have robot dogs, Phillips robot cats (albeit stuck sitting in one place) but Ugobe have little robot dinosaurs called Pleo. In the videos they do move like little baby creatures and the lady in the shopping mall coos over one as she strokes it.

Central to Pleo seems to be:

  1. Designing Sociable Robotsembodiment – they feel through 40 sensors and move in their environment
  2. emotion – they have a relatively complex model of basic drives rather like Cynthia Breazwal describes in her book “Designing Sociable Robots“.

This seems to pay off in people’s reactions, both on Pleo’s own videos (well they would!), but also in owner’s plogs (sic) … one owner says:

“she acts just like a cat concerning keyboards.. just crawl on the darn thing while I’m typing! I know Penny,. you’re so cute it doesn’t matter what you do. But you should have a little sensor strip in your butt to spank when you’re bad1 or to pat gently to urge you to go explore. Go to sleep my little love” ArcticLotus

For researchers there is an open architecture so it should be possible to play oops experiment with them 🙂 The API doesn’t seem to be published yet, so wait until you get your cheque books out!

I just wanted to print a file

I just wanted to print a file, now it is an hour and a half later and I still have nothing … this is where all our time goes gently coaxing our computers in the hope they may do what we ask.

Such a simple thing to want to do … and so much pain on the process, and so many simple things that application designers could do it make it better.

Physicality and Middle Ages Tech Support

Ansgarr needing help to use a bookOn the forum of our MRes course at Lancaster one of the students posted a link to Middle Ages Tech Support on YouTube. It shows Ansgarr a Mediaeval monk struggling with his first book.

I first saw this video when I was giving a talk at University of Peloponnese in Tripolis. Georgios1 showed the video before I started, just because he thought it was fun. I was talking a little bit about physicality and the video brought up some really interesting issues relating to this and usability. Although it is a comic video we can unpack it and ask which of the problems that Ansgarr has as he changes technology from scroll to book would actually happen and which are more our own anachronistic view of the past.

Usabilty and Web2.0

Nad did a brilliant guest lecture for our undergraduate HCI class at Lancaster on Monday. His slides and blog about the lecture are at Virtual Chaos. He touched on issues of democracy vs. authority of information, dynamic content vs. accessibility and of course increasing issues of privacy on social networking sites. He also had awesome slides to using loads of Flickr photos under creative commons … community content in action not just words! Of course also touched on Web3.0 and future convergence between emergent community phenomena and structured Semantic Web technologies.

matterealities and the physical embodiment of code

Last Tuesday morning I had the pleasure of entertaining a group of attendees to the Matterealities workshop @ lancaster. Hans and I had organised a series of demos in the dept. during the morning (physiological gaming, Firefly (intelligent fairylights), VoodooIO, something to do with keyboards) … but as computer scientists are nocturnal the demos did not start until 10am, and so I got to talk with them for around an hour beforehand :-/

The people there included someone who studied people coding about DNA, someone interested in text, anthropologosts, artists and an ex-AI man. We talked about embodied computation1, the human body as part of computation, the physical nature of code, the role of the social and physical environment in computation … and briefly over lunch I even strayed onto the modeling of regret … but actually a little off topic.

Alan driving

physicality – Played a little with sticks and stones while talking about properties of physical objects: locality of effect, simplicity of state, proportionality and continuity of effect2.

physical interaction – Also talked about the DEPtH project and previous work with Masitah on natural interaction. Based on the piccie I may have acted out driving when talking about natural inverse actions

ubiquity of computation – I asked the question I often do “How many computers do you have in your house” … one person admitted to over 10 … and she meant real computers3. However, as soon as you count the computer in the TV and HiFi, the washing machine and microwave, central heating and sewing machine the count gets bigger and bigger. Then there is the number you carry with you: mobile phone, camera, USB memory stick, car keys (security codes), chips on credit cards.

FireFly on a Christmas treeHowever at the Firefly demo later in the morning they got to see what may be the greatest concentration of computers in the UK … and all on a Christmas Tree. Behind each tiny light (over 1000 of them) is a tiny computer, each as powerful as the first PC I owned allowing them to act together as a single three dimensional display.

embodiment of computation – Real computation always happens in the physical world: electrons zipping across circuit boards and transistors routing signals in silicon. For computation to happen the code (the instruction of what needs to happen) and the data (what it needs to happen with and to) need to be physically together.

The Turing Machine, Alan Turing’s thought experiment, is a lovely example of this. Traditionally the tape in the Turing machine is thought of as being dragged across a read-write head on the little machine itself.

However … if you were really to build one … the tape would get harder and harder to move as you used longer and longer tapes. In fact it makes much more sense to think of the little machine as moving over the tape … the Turing machine is really a touring machine (ouch!). Whichever way it goes, the machine that knows what to do and the tape that it must do it to are brought physically together4.

This is also of crucial importance in real computers and one of the major limits on fast computers is the length of the copper tracks on circuit boards – the data must come to the processor, and the longer the track the longer it takes … 10 cm of PCB is a long distance for an electron in a hurry.
Alanbrain as a computer – We talked about the way each age reinvents humanity in terms of its own technology: Pygmalion in stone, clockwork figures, pneumatic theories of the nervous system, steam robots, electricity in Shelley’s Frankenstein and now seeing all life through the lens of computation.

This withstanding … I did sort of mention the weird fact (or is it a factoid) that the human brain has similar memory capacity to the web5 … this is always a good point to start discussion 😉

While on the topic I did just sort of mention the socio-organisational Church-Turing hyphothesis … but that is another story

more … I recall counting the number of pairs of people and the number of seat orderings to see quadratic (n squared) and exponential effects, the importance of interpretation, why computers are more than and less than numbers, the Java Virtual Machine, and more, more, more, … it was very full hour

real personal information management

Some of my research is in an area that is called ‘personal information management’ or PIM. PIM is about all the bits of information people store electronically: files on the computer desktop, web bookmark, calendars and address books and increasingly photos, movies and more.

However, physical information management can be just as fascinating … and a lot more creative.

after the ball is over …

Last week’s HCI2007 conference and the Physicality workshop now all finished (except sorting out the the final finances for HCI … but I’ll forget that for now!)

Being part of the organisation of things you always see so many things that are not as planned (like going wrong), but for the delegates it all seems a well-oiled machine. In this as in many other domains, the mark of a rubust system is not whether or not it fails, but how it copes with failure. This is the heart of my principles for appropriate intelligence when designing ‘intelligent’ user interfaces and also ‘fail fast programming’1 when designing and debugging critical computer systems.

Great to see so many old friends … and meet new people … and after able to show Nad2 the glories of the Lake District.
