It seems like a lot of time has passed between this blog post and my previous one. I begin this entry with an explicit statement of: less time will pass between this one and the next!
This post is all about an accessibility conference that I recently attended in Seville, Spain, on behalf of the EU4ALL project in which the Open University has played an important part. Before saying something about the themes of the Aegis conference and summarising some of the notes that I made during some of the presentations, I guess I ought to say something about the project (from an outsiders perspective).
Aegis is an EU funded project that begins with a silent O (the O stands for Open). It then continues to use the first letters of the words Accessibility Everywhere: Groundwork, Infrastructure, Standards. My understanding is that it aims to learn more about the design, development and implementation of assistive and accessible technologies by not only carrying out what could be termed basic research, but also through the development and testing of new software.
Without further ado, here is a rough summary of my conference notes, complete with accompanying links. I hope it is useful to someone!
Opening
After Evangelos Bekiaris presented the four cornerstones of the project (make things open, make things programmatically accessible, make sample applications and make things personalisable), Miguel Gonzalez Sancho outlined different EU research objectives and initatives. It was stated that 'there must be research in the area of ICT and accessibility, and this will continue'.
Pointers towards future research included a FP7 call that related to ICT for aging and well being. Other subjects mentioned included the areas of 'tools and infrastructures for mainstream accessibility', 'intelligent and social computing for social interaction' (which would be interdisciplinary, perhaps drawing upon the social sciences) and 'brain-neuronal computer interfaces' (BNCI), as well as plans to develop collaborations with other parts of the world.
It was useful not only get an overview of the domains that the funders are likely to be interested in, but also useful to be given a wealth of information rich links that researchers could explore later. The following links stood out for me: the EC ICT Research in FP7 site and the e-Inclusion activities page.
The Aegis Concept
Peter Korn from Oracle presented a very brief history of accessibility, drawing on the notion of 'building in accessibility' into the built environment. He presented a total of six steps, which I hope I have noted down correctly.
The first is to define what 'accessible' is. This may involve the taking of measurements, such as the width of doors and maybe the tones of elevators, or the sounds that are made of road crossings. The next (second) stage is to create standard building materials. Here you might have a building company creating standard door frames or even making electronic circuits to make consistent tones and noises (this is my own paraphrasing!). The next step is to create some tools to know how best to combine our pieces together. The tools may take the form of standardised instructions.
The next three items are more about the use of the physical items. The fourth step is that you need to make a choice as to where to place a building. Ideally it should be situated close to public transport and in a convenient place. The fifth step is to go ahead and to 'build' the building. The final step is all about dissemination: the telling of people about what has been created.
Peter drew a parallel between the process of creating physical acccessibility and creating accessibility for ICT systems. There ought to be 'stock' components of interface elements (such as the Fluid component set), developers and designers should adhere to good practice guidelines (such as the WCAG guidelines), applications need to be then created (which is akin to going ahead and making our building), and then we need to tell others what we have done.
If my memory is serving me well, Peter then went onto talk about the different generations of assistive technologies. More information about the generations can be found by jumping to my earlier blog post. From my own perspective (as a technologist), all this history stuff is really interesting, but there's such a lot of it, especially when technology is moving on so quickly. Our current challenge is to begin to understand the challenge of mobile devices and learn about how to develop tools and systems that remain optimally functional and accessible.
Other Projects
One of the great things of going to conferences (other than the cakes, of course) is an opportunity to learn about loads of other stuff that you had never heard of before. Blanca Alcanda from Technosite (Fundacion ONCE) spoke briefly about a number of projects, including T-Orienta (slideshare), Gametel (the development of accessible games) and INREDIS (self-adaptive inverfaces).
Roundtable Discussion
Karen Van Isacker was our question master. He kicked off with few killer questions (a number of which he tried to answer himself!) The panel comprised of a journalist, industrialists, researchers and user representatives. The notable questions were: ' what are your opinions about the [Aegis] products that are being developed?', 'how are you going to make sure users know about the tools [that are being developed]?', 'what are the current barriers people face?', and 'can you say something about the quality of AT training in Europe?'
In many ways, these questions were addressed by many of the conference presentations as well as by the panel. Challenges relating to the development of assistive technologies include the continual necessity of maintenance and updates, that users ought to be more aware of the different types of technologies that may be available, the price of technology is significant and one of the significant challenges relating to training is the fact of continual technological change.
After a short break the conference then split into two parallel sessions. I tended to opt for sessions that focussed on more general issues rather than those that related to particular technologies (such as mobile devices) or operating systems. This said, there is always a huge amount of cross over between the different talks.
Parallel session 1b (part 1)
It was good to see a clear presentation of a user centred design methodology (UCD) by Evangelos Bakiaris. Evangelos described user research techniques such as interviews, questionnaires and something called contextual enquiry. His talk reminded me of materials that are presented through the Open University course Fundamentals of Interaction Design (a course which I wholeheartedly recommend!)
My colleague Carlos Velasco from FIT, Germany, gave a very concise outline of early web software before introducing us to WCAG (W3C). Carlos then went onto summarise some intresting research from something called the 'technology penetration report' where it was discovered that out of 1.5 million websites, 65% of them use Javascript (which is know to yield challenges for some assistive technologies). The prevalance of Javascript relates to the increasing application and development of Rich Internet Applications (or RIAs, such as Google Maps, for instance). The characteristics of RIAs include the presentation of engaging UI's and asynchronous content retieval (getting many bits of 'stuff' at the same time). All these developments led to the creation of the WAI-ARIA guidelines (Accessible Rich Internet Applications).
Carlos argued that it was once relatively straightforward to test earlier types of web application, since the pages themselves didn't change. You could just send the pages to an 'page analysis server' or system (perhaps like Imergo), which may then persent a report, perhaps in a formal language like EARL (W3C). Due to the advent of RIAs, the situation has changed. The accessibility of a system very much depends on the state in which it is, and this can change. Testing web accessibility has therefore changed into something more resembling traditional usability testing.
A higher level question might be, 'having an application or product that is accessible is all very well, but do people have access to assistive technology (AT) that enable web sites to be used?' Other related questions include, 'if people have access to AT, do they use it? If not, why not?' These were the questions that Karel Van Isacker aimed to address.
Karel began by saying that different definitions within Europe leads to different estimates of the number of people with disabilities. He told us that the AT supplier market is rather fragmented: there are many suppliers in different countries and there are also substantial differences in terms of how purchases of AT equipment can be funded. He went on to suggest that different countries applied different models of disability (medical, social and consumer) to different market segments.
Some of the challenges were clear: people were often unaware of the solutions that best meet their ICT needs, users of AT's are just given very rudimentary training, and many people may even have a computer that they have used once, and there is a high level of users discarding their AT due to low levels of satisfaction.
Parallel session 1b (part 2)
Francesca Cesaroni began the next part of the afternoon by describing a set of projects that related to the broad theme of user requirements. These included the VISIOBOARD project (which related to eye tracking) and the CAALYX project (Complete Ambiant Assisted Living Experiment).
Harry Geyskens then went on to consider the following question from the perspective of someone with a visual impairment: 'how can I use a device in a comfortable and safe way that is good as a non-disabled person?' Harry then presented different design for all principles (wikipedia) : that a product must be equitable in use, be flexible, be simple and intuitive, provide perceptable information, be tolerant for error, permit usage through low physical effort.
Begona Pino gave an interesting presentation about the use of video game systems and how they could potentially be used for different groups, whilst clearly expressing a call for design simplicity.
The final talk of the day was given my yours truly, where I tried to present a summary of four year project called EU4ALL in twenty minutes. To summarise, the aim of EU4ALL is to try to consider how to enhance the provision of accessible systems and services in higher eduction through the creation of a small number of prototype systems. A copy of my presentation and accompanying paper can be found by visiting the OU knowledge network site (a version will eventually be deposited into the Open Research Online system).
Day 2 keynote
Gregg Venderheiden kicked off day 2 with a keynote entitled 'Roadmap for building a global public inclusive infrastructure'. Gregg imagined a future where user interfaces change to the needs of individual users. Rather than presenting a complicated set of interfaces, a system (a PC or mobile device) may present a more simplified user interface. Gregg pointed us to a project called NPII (National Public Inclusive Infrastructures). It was good to learn that some of the challenges that Gregg mentioned, specifically security and ways to gather preferences were also lightly echoed in the earlier EU4ALL presentation.
Parallel session 2a: Rich RIA!
RIA is an abbreviation for Rich Internet Application. The canonical example of a RIA is, of course, Google Maps or Gmail. Web application development techniques (such as AJAX, wikipedia) that were pioneered by Google and other organisations have now found their way into a myriad of other web products. From their inception RIAs proved to be troublesome for users of assistive technologies.
Juta Trevianus gave a talk with an intreguing title: 'changing the world - on a tiny budget'. She began by saying that being on-line and being connected is no longer an option. Digital exclusion can lead to social exclusion. The best bargain is often, in my experience, one that you can find through a web browser. I made a note of some parts of her talk that jumped out at me, i.e., 'laws work when they are clear, simple, consistent and stable', but, 'laws cannot create a culture of change'. Also, perhaps we need to move from a case where one size fits all (universal design) to the case where one size fits one (personalised design, which may be facilited through technology).
Being an engineer, I was struck by Juta's quote from computer scientist Alan Kay: 'the best way to predict the futuer is to invent it'. It's not too difficult to relate this quote back to the Aegis theme of openness and open source software (OSS): freedom of code has the potential enable the freedom of invention.
The first session was concluded by Dominique Hazael-Massieux from the W3C mobile web initative (W3C). The challenges of accessibility now reach much further than the increasingly quaint desktop PC. They now sit within the hands and pockets of users.
One early approach to dealing with the explosion of new devices was to provide a separate websites: one for mobile devices, another for 'traditional' computers. This approach yields the inevitable challenge of maintenance. Dominique told us about HTML 5 (wikipedia) and mentioned that it has the potential to help with site navigation and make it easier for developers (and end users) to work with rich media.
The remainder of the day was mainly focused upon WAI-ARIA. I particularly enjoyed Mike Squillace's presentation that returned to the challenge of testing rich internet applications. Mike presented some work that attempted to codify with WCAG rules into executable Javascript which could then be used within a test engine. Jan Richards, from OCAD, Canada, presented the Fluid project.
Parallel session 3b: Standardisation and valorisation
I split my time in the final afternoon between the two parallel sessions, visiting the standardisation session first, then moving onto the coordination strand half way through. There were presentations that described the process of standardisation and its importance in the process of accessibility. During this session Loic Martinez presented his work on the creation of a tool to support the development of accessible software.
Parallel session 3a: Coordinating research
The final session of the conference yielded a mix of presentations, ranging from description of physical centres that people could visit through to another presentation about the EU4ALL project made by my colleague from Madrid. This second EU4ALL presentation outlined a number of proposed prototype accessibility information services. Our two presentations complemented each other very well: my presentation outlined (roughly) an accessibility framework, whereas this second presentation seemed to an alternative perspective on how the framework might be applied and used within an institution.
Summary
One of the overriding themes was the necessity to not only make assistive technology available to others but also to make sure the right kind of technology was selected, and to ensure that users were given ample opportunity to learn how to use it. If you are given a car and you have never driven before you shouldn't just get into it and start driving: it takes time to learn the controls, and it takes time to build confidence and to learn about the different places you might want to go to (and besides, it's dangerous!) To risk stretching a metaphor too far, this is a bit like assistive technologies: it takes time to understand what controls you have at your disposal and where you would like to travel to. As Karol pointed out in his talk: far too much technology sits unused in a box.
Another theme of the conference was about the solidity of 'this box'. Rather than having everyting in 'a box' or installed on your computer (or mobile device), perhaps another idea might be to use technology 'on demand' from 'the cloud' (aka, the internet). Tools may have the potential to be liberated, but this depends on other types of technology 'groundwork' being available, i.e. good, fast and reliable connectivity.
Finally, another theme (and one that is pretty fundamental) is the issue of usability and simplicity. The ease of use of systems will continue to be a perpetual challenge due to the continual differences between people, task and context (where the person and the task takes place). Whilst universal design offers much possibility in terms of making product for the widest possible audience, there is also much opportunity to continue to explore the notion of interface, product and system personalisation. Through simplicity comes accessibility, and visa versa.
All in all, a very interesting couple of days. I came away feeling that there was a strong and vibrant community committed to creating useful technologies to help people in their daily lives. I also came away feeling that there is so much more to do, and a stronger feeling that whilst technology can certainly help there are many other complementary actions that need to be taken before technology can even begin to play a part.
