EQUAL Research Council workshop on accessibility

This workshop held at the University of Reading last week produced much food for thought.

John Gill, chief scientist at the RNIB, kicked off the day's sessions with a comprehensive run-through of the problems besetting those individuals with less than 100% of our faculties (which is most of us). Su Brown (Microsoft UK) followed this with an account of her company's accessibility input to the Inland Revenue's tax credit website (basically, contract out and forget about it), which didn't go down too well with the audience.

Computer professional Steve Nutt followed up with a live demo of how well the program Talx gives access to non-sighted users of Nokia Communicators. Excellent. Simeon Keates then showed us some of the issues involved in designing public kiosks for disabled users - he has extensive experience working on these issues with Royal Mail. Then Peter Kyberd gave us a demo of intelligent limb development, with squidgy rubber bits to hand around to boot.

After lunch, Kerstin Dautenhahn described her work on developing robots for use in autism therapy, while Gareth Evans gave an account of how documents produced by the blind may differ from those produced by others, and how such individuals can be supported to improve the documents they draft. Penny Standen then described some of the issues surrounding computing for people with learning disabilities. She then covered the work carried out by her team to create improved input devices for this group. The day was rounded off by Geoff Cook's team from Reading, describing their usable and accessible solution for a hospital patients' portal for information, communication and entertainment.

The issue for me at the centre of this workshop - silent but loud - was the absence of public policy figures. And here was an array of innovative projects funded by central government and presented at a government-funded workshop designed to bring researchers, practitioners and policy-makers together. Practitioners are often criticised for not getting up to speed, but they were there in force. Yet while there were certainly a few - very few - local authority and autonomous agency representatives present, central government was notable by its absence. For example, it is a massive omission that nobody respresentative of those contracting for the inaccessible Patientline system (increasing numbers of NHS Trusts, and ultimately the Department of Health) was there to hear how it should be done, and to hear why they shouldn't be contracting for easy (cheap - for hospitals - and short-term) but unusable, non-accessible (and for patients, expensive) solutions like Patientline.

Intuitive, intuitable, intuition
As always, the subject of 'intuitive' raised its evil little head at the Oxford Politics of Code conference a few days ago. What exactly 'is' 'intuitive', or rather 'intuitable'?

In a paper published in the Communications of the ACM in 1994 (that is, nine years ago) Jef Raskin was quite clear: when it comes to HCI, "Intuitive equals familiar". He discussed the possible intuitable qualities of the computer mouse, and rejected such a supposition. I seem to recall he published a not unsimilar discussion in his book The Humane Interface, following an encounter with a non-user of mice (mouses ;-)). [BTW, the 'Intuitive' paper is also available on Tog's site at http://www.asktog.com/papers/raskinintuit.html .]

But according to one member of staff at Oxford University (on the software side of the house) present at said conference, the computer mouse is completely intuitive (that is, intuitable), but experience is not part of his intuition equation: instinct is. In other words, the mouse arrivses on the desktop fresh from the primaeval forest, part of the basic toolset of hunter-gatherers, ready to be understood by all regardless of background or education....

Intuitive meaning 'instinctive' is clearly different from intuitive meaning 'can be more easily learned based on similar past experiences'. The intuition of software engineers in these matters can clearly paseth all understanding (no, they can never be 'normal users' as in 'find some normal users to test this system on').

Bloogle? Byoogle?
The blogging news of the weekend is that Google has bought Pyra, the company that provides this Blogger software. The story was broken by Dan Gillmor on Saturday in his blog. Ev's blog about selling the company's here. Steve Jenson, a self-confessed geek that works on Blogger and elsewhere, said on Saturday that, "this won't mean a big change for existing users [...]; Blogger isn't going anywhere, our plan to get lots of new features out the door, new versions of the product, better support, etc, are only strengthened by this new development. One thing this will mean is lots more servers, more resources, and more coworkers to help out with everything! I'm really excited; things are going to rock. Heck, things are starting to rock already."

So, some issues.

Will Blogger get better? I expect so. I'm looking forward to the day that commenting becomes part of the package, avoiding the need for Bloggers to integrate third party packages.

Second, will Blogger get rebadged with a moniker appropriate to the Google farm (Froogle etc)? Byoogle? Bloogle?

Finally, what's in it for Google? Well as Tony Pierce points out, "if Google had a faster access to blogs, it would have seen all the activity [other people's blogs] pointing to Gillmor's blog, and to the Merc article [by Gillmor], and to Ev's page [blog] and would have basically figured out that it's news." So will this finally change the nature of news (the eternal 'it's a blog but is it journalism' issue).

One thing is certain: the move will certainly fuel the debate as to whether Google aims to 'roole the world', and whether global domination by Google would be a good or bad thing.

Just rewards?
The Guardian reports today that Create Online, the trendy online new media design mag, has bitten the dust. This brings to mind a blog from Tom Smith back in December, entitled 'Fuck Off Customers' reporting without comment Sprite Interactive's response to Toni & Guy website visitors who did not have broadband (see his blog title). As Tom so aptly puts it, a prime example of "dot bomb arrogance". Is Create reaping its just desserts?

Killer App?

The Register reports the first known use of a mobile picture phone for convicting criminals. A tobacconist tipped off Italian police with images of a pair of suspicious characters.

Userati

Following my suggestion that Userati lacks a logo, Chris has suggested that such a logo should include Mobius strips. I know what he means ;-)

EQUAL addressing deaf ears?
I spent part of yesterday at a Engineering and Physicial Sciences Research Council (EPSRC) EQUAL research workshop on accessibility issues, held at Reading University's department of computing.

While all the presentations provided marvellous insight into a broad range of recent developments in the accessiblity field, with truly inspiring speakers, a number of whom had a series of significant disabilities, what is of concern is that few policy makers made an appearance at this cross-disciplinary event (despite having being invited by the organisers). Meanwhile in my own experience, policy-makers continue to appear to be 'blind' to accessibility and usability concerns (which are parallel but different), going by their recent publications, such as the recent NHS National Programme Request for Information. As EQUAL director professor Peter Lansely said, although they haven't been going for long and he's always inviting policy makers to events, to date there have been few public sector takers.

EQUAL Co-ordinator Verity Smith promises that workshop slides will follow, and I'll link to them when they do.

Creativity and code
Lawrence Lessig delivered a powerful speech at the Oxford Union last week, courtesy of the Oxford Internet Institute and the Oxford University Centre for Socio-Legal Studies, joint hosts of the Politics of Code conference.

While pointing to the hypothetical freedom we presume to have on the Internet 'because the technologists said so', Lessig - the recent loser in the US Supreme Court copyright judgment Eldred v. Ashcroft - argued that recent legal moves are making the Internet far more regulated than the physical world.

If on the Internet every act is a copy, then every access of every digital document, every thing, becomes a case of publication. This effectively grants rights to publishers far beyond those available in 'real space', where only the generation of an additional physical copy causes copyright law to kick into force (reading, giving or selling a copy are all in fact unregulated activities in 'real space'). Lessig argued that this advance of the digital copyright holders - invariably the large corporations - has arisen because legislators have not yet understood the Internet.

Using the examples of Middlemarch - a book clearly now in the public domain - and Aristotle's Politics - a text never subject to copyright in its original form - Lessig described how e-book readers forbid the copying or pasting of text selections from non-copyright works, or arbitrarily forbid their buyers from listening to 'read aloud'.

Such texts have become presumptively regulated because of an accident of technology design, argued Lessig.

Creativity is constrained, with copyright owners wielding the US Digital Millennium Copyright Act (DMCA) against innocents attempting to create new interactions. The DMCA has been used to try and prevent a Sony Aibo fan from producing and distributing code that teaches these pets to 'dance jazz'. However legal dancing jazz may be, Sony's lawyers decided to send threatening letters to the 'rogue' fan. On the Internet, fair use - perfectly permissible under national laws in 'real space' - disappears. (While copyright violation has never been a criminal act, the DMCA now turns anyone who tries to circumvent digital protective mechanisms into a criminal.) Lessig argued that the increase in term, scope and reach of copyright control now threatens to alter fundamentally how creativity functions, and therefore affects the entire practice of cultural creation.

Responding to Peter Davies, Visiting Fellow at the OII, concerning the latter's claim that copyright terms were extended under US law "to give artists more protection", Lessig was firm, in the tradition of his Oxford Union venue: "Bullshit! This is not about protecting artists at all - these artists are all dead. The benificiaries are the major corporations."

The conclusion of Lessig's argument is that current trends in copyright law and the obsession of large corporations with protecting their intellectual property are already affecting the usability of products, and will lead to more of the same anti-creative repression if the content industry continues to see the Internet as merely a means for conducting piracy of their content rather than as a creative medium in its own right.

It's hardly surprising that Luddite industry, unable or unwilling to discover new business models, should seek to impose a protectionist position. What is surprising, says Lessig, is that governments should be so keen to take the side of the large corporations against the general public, both consumers and creators.

While gloomy about possible solutions, Lessig's conclusion was that by letting ordinary people understand what has happened - much in the same way as the activities of the pharma companies selling AIDS drugs to South Africa was highlighted - it might be possible to generate a change of heart among legislators to help alter the balance in this debate. We can live in hope that when 'consumers' realise the extent to which they are being taken to the cleaners, they will up arms and rebel against corporate greed.

PS I've just spotted this article concerning the same issue by Stephen Downes, courtesy of Lucdesk.

PPS And now having caught up with the Sunday papers on Monday evening, I find that John Naughton also addressed the subject of copyright on the Internet in his Observer column.

Engrish as she is spoke (or not)
You will scream when you see these: The Twin Towers (Lord of the Rings) captions in 'Engrish' ('Engrish' is often what we see coming out of Babelfish and similar programs).

With extensive experience of translation myself, perhaps these are not unexpected - I have my own vast collection of painful texts - but it's weird that these things never cease to amaze...

English As She Is Spoke was of course the title of a much-derided phrasebook compiled by two Portuguese translators in the 19th century. To see how far machine translation has progressed, check out this fun comparison of how well the Babelfish translator fares against the original hilarious 19th century text. And if anyone tells you that machines translation programs are perfectly capable of producing good translations these days, just point them to that page.

E-voting: growing concerns
Professor David Dill (Stanford University) is running a campaign of opposition to unaudited electronic voting. Many US scientists have already endorsed his statement on electronic voting, including Barbera Simons (Co-chair, U.S. Public Policy Committee of ACM and Former ACM President), veteran campaigner Rebecca Mercuri (Bryn Mawr College), Ronald Rivest (MIT), Babara Liskov (MIT), Michael Fischer (Yale), Leslie Lamport (Microsoft), David Touretzky (Carnegie Mellon), Susan Landau (Sun), Lori Clarke (Massachusetts) and David Dobkin (Chair of the Department of Computer Science at Princeton).

Following a recent correspondence concerning possible 'across-the-pond' collaboration on this issue, David Dill has now passed on information from another campaigner he's heard from, this time in Europe. Emanuele Lombardi in Italy has set up http://www.electronic-vote.org. He's concerned about the dangers of the unaudited systems being proposed: "Here [in Italy] there is no discussion at all about the topic. Most of the Italians accept everything new just because it's new and no one seems to have any doubts about the electronic vote."

The UK's Computer Weekly in this week's edition (30 January) once again reported that the UK government plans to press ahead with e-voting plans at the May local elections. Eighteen councils are to trial new systems across all wards, in the largest test to date. You can find out more about current plans on the UK government's website devoted to the issue.

Is it about time we did something more in the UK to open up the debate on e-voting? To misquote a certain nursery rhyme, when things are good, they can be very very good, but when they are bad they are pretty horrid, this being just as true of e-voting as of any other sphere of life. The Foundation for Information Policy Research, in the capable hands of Ian Brown at my alma mater, UCL, hosted a seminar given by Rebecca Mercuri in London at the end of last year on this matter. Perhaps the next steps now need to be taken to generate wider public discussion...

One thing that never ceases to surprise is that whenever the UK government buys anything electronic, it always believes everything the system seller promises.
