Behavioural Stratergies of Visually Disabled ‘Surfers’ [#accessibility #a11y]

The World Wide Web (Web) is a crucial resource for the employment, social networking, and entertainment of visually disabled1 users. However, Web pages are designed for visual interaction, and badly built pages, or those transformed into alternative forms (e.g, audio) by assistive technologies, loose the richness of the visual presentation and structural formatting, thereby becoming inaccessible. Our previous studies  suggest that visually disabled users encounter two types of problem: those which are expected and can be adapted to, and those which are difficult and stressful, and can only be handled by coping.

Adaptation strategies include routine, even automatic, modes of getting along, whereas coping strategies are problematic adaptations that require new responses or special efforts; seen as last–resort activities signified by increased stress, increased frustration, increase browse time, increased task completion time, or an inability to interact with the page. We believe that adaptation is a perfectly acceptable mechanism for addressing change, however, we see coping as being driven by the need to address inadequacies in the technology in an attempt to re-engage with the content and re-attain the richness of the visual format.

We understand that the extent of our work will be, to some degree, determined by the ongoing results of the study. Nevertheless, our objective is to develop a deep understanding of how visually disabled users cope with inaccessible Web pages to facilitate more effective accessibility interventions such that the need to cope is removed.

In this case, we believe that the only way to accurately capture these strategies is by a longitudinal ethnographic study in co-operation with our observational partners. Augmented with a remote analysis of the mailing lists and discussion forums in which we have previously seen possible behavioural strategies exchanged.

Well at least that’s what I wrote in the funding application – really as a continuation to Yeliz Yesilada’s initial work and its continuation in Darren Lunn’s CASTA – ‘Coping Strategy Analysis to Support Transcoding Algorithms’ – work [1, 2, 3, 4, 5] . I’m pleased to say that the Basque Government liked it and now Markel Vigo is taking up a research position spending two years with us here in Manchester and then a final year with Julio Abascal at the University of the Basque Country.

Back to Bush

Vannevar Bush

Portrait of Dr. Vannevar Bush of Carnegie Inst., Smiling - Photographic Print

I’ve noticed a spate of ‘Bush-bashing’ as of late! NO, I don’t mean George or George W. I mean the man Vannevar.

From the panel session at HT2010 to Mark Bernstein’s blog to the Paul De Bra’s recent unKeynote at Web Art Science and general ascent from various audience members – indeed, I think Dave Millard and Alan Dix also agree with Mark and Paul’s observations.

There seems to be two general assertions: firstly that Bush does not propose Hypertext because Hypertext as Ted Nelson sees it (and therefore we see it) is different, and secondly that ‘As We May Think’ was such ‘popular science’ – getting ‘predictions’ both right and wrong – as to render it nearer to fiction such as Murray Leinster’s 1946 short story, “A Logic Name Joe” or H. G. Wells “The World Brain”. However, I assert that there is some inconsistent argumentation here and some different standards by which we are judging ‘As We May Think’ and the ideas contained within it.

Firstly, we seem to be saying that ‘As We May Think’ is a prediction of what is to come, while other later visions of Hypertext are either definitions or statements of requirements, but this surely can’t be true – most of the ideas in ‘Literary Machines’ have not yet come to pass but we still hold this up as a definition or roadmap of Hypertext.

Secondly, for us to then assert that something postulated before our definitions of hypertext should in some way retrospectively fulfil all aspects of that definition seems way off base to me – ‘As We May Think’ does propose hard linking and trails, but just because these don’t exist in our definitions of hypertext doesn’t mean that ‘As We May Think’ isn’t hypertext’s logical pre-cursor.

Thirdly, “A Logic Named Joe”, “The World Brain”, or even work on the “Statistical Machine” cannot be held up as hypertext pre-cursors because none of these where cited as THN’s or TBL’s inspiration for Hypertext or the Web – ‘As We May Think’, however, was. What’s more, ‘As We May Think’ is based on very real technology and experiments underway at MIT during this time – the Rapid Selector and the Photocomposer. While, the “Statistical Machine” is patented in 1931 (US patent 1,838,389, 29 December 1931) it is a document search engine (not a browser and linker) and I have no idea if it really did exist or if it is only a patented idea; however, “A Logic Named Joe” and “The World Brain” are fantasy vapour.

Finally, the contention around building trails and trailblazers – suggest no inconsistency to me, we have no idea if the linking or the trails are held as kind of linkbases – and we don’t seem to be criticizing ‘Walden Pathways’, ‘Guided Tours’, or the many Web based trail systems.

It seems to me that ‘As We May Think’ is the rightful  pre-cursor to Hypertext thinking because it suggests associative linking and selection by association, it allows those associations to be made and browsed, the ideas contained within it are based on real technology (even if these are incomplete and under different names), and finally because THN tells us so in ‘Literary Machines’ in which he prints ‘As We May Think’ verbatim.

Authonomy Points the Way to Open Peer Reviewing

Authonomy from HarperCollins

HarperCollins Authonomy

Authonomy is a unique online community that connects readers, writers and publishing professionals. It was conceived and built by editors at HarperCollins Publishers. They are in ‘beta’ at the moment, so they’re still developing and perfecting the site. Authonomy invites unpublished and self published authors to post their manuscripts for visitors to read online. Authors create their own personal page on the site to host their project – and must make at least 10,000 words available for the public to read. Visitors to Authonomy can comment on these submissions – and can personally recommend their favourites to the community. Authonomy then counts the number of recommendations each book receives, and uses it to rank the books on the site. It also spots which visitors consistently recommend the best books – and uses that info to rank the most influential trend spotters.

This kind of ethos, certainly that the community decides, is shared by PLoS ONE who say that too often a journal’s decision to publish a paper is dominated by what the Editors think is interesting and will gain greater readership. They rationalise that these  subjective judgements can lead to decisions which are frustrating to the author – and lead to bad science. In this case they peer-review the submissions and publish all papers that are judged to be technically sound. Judgements about the importance of any particular paper are then made after publication by the readership (who are the most qualified to determine what is of interest to them).

PLoS ONE

Public Library of Science - ONE

So is this the way for Human factors and HCI review, well I think so. We need a combination of non-judgemental review as per PLoS ONE with open paper review to encourage quality. Indeed, open reviews have been gaining popularity in other domains for sometime [1] championed by the British Medical Journal:

…Schroter says the journal decided to introduce its policy of signed reviews based on the logic that signed reviews might be more constructive and helpful, and anecdotally, the editors at BMJ say that is the case. JAMA‘s Rennie says he doesn’t need research data to tell him that signing reviews makes them better. “I’ve always signed every review I’ve ever done,” he says, “because I know if I sign something, I’m more accountable.” Juries are not anonymous, he argues, and neither are people who write letters to the editor, so why are peer reviewers? “I think it’ll be as quaint in 20 years’ time to have anonymous reviewers as it would be to send anonymous letters to the editor,” he predicts.

So here’s the test – for the next year I’m going include the following on all reviews:

Open Review: I am tired of receiving unfair, unconsidered, short, or unhelpful reviews – I personally do not mind the rejection but I do mind not being able to make my next submission better. It seems to me that having reviewer information obscured may be a partial explanation for these kinds of reviews and this may not be the best way to conduct scientific research in the future – especially in the collaborative cross-disciplinary domains within which I normally work. Therefore, in the interests of transparency, this paper was reviewed by Dr Simon Harper at the University of Manchester (UK). My objective was to give honest feedback to make your work better and my reviews more considered, I did not wish to say anything here which I would not say in a face-to-face discussion. If you feel this review was either unfair or unhelpful then please let me know, and I will endeavour to do a better job next time.

I’m going to see if I think my review quality increases, see if I get any feedback, and see how the conferences and journals for which I review handle the statement.

2010 In Review

WordPress sent over the descriptive states for last year for ‘Thinking Out Load’ , and formulated a high level summary of its overall blog health:

Healthy blog!

The Blog-Health-o-Meter™ reads Fresher than ever.

Crunchy numbers

A Boeing 747-400 passenger jet can hold 416 passengers. This blog was viewed about 3,000 times in 2010. That’s about 7 full 747s.

In 2010, there were 31 new posts, not bad for the first year! There were 62 pictures uploaded, taking up a total of 43mb. That’s about 1 picture per week.

The busiest day of the year was April 13th with 116 views. The most popular post that day was Five Users Do Not Make a Study.

Where did they come from?

The top referring sites in 2010 were twitter.com, researchblogging.org, WordPress Dashboard, netvibes.com, and Google Reader.

Some visitors came searching, mostly for merry christmas 2010, merry christmas, web-based interaction: a review of three important human factors, as we may think, and web based interaction.
