    • Standards for the next generationof accessibility - BS8878 Jonathan Hassell Chair, BSi IST/45 BS 8878 launch event 7th December 2010 © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • BS8878 – context & history © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • A brief history of British accessibility standards…• why did we need a British Standard? – because we have British law around accessibility • and not just for public-sector websites, all sites… – in 2005, research by the British Disability Rights Commission revealed sites weren’t doing well • and no existing standards made it easy enough for site owners to know what to do• so the DRC commissioned BSi to create PAS-78 to try and help – a guide to the process of commissioning, producing and maintaining a website from a site owner’s point of view – a non-technical person’s guide to how standards should be used to help ensure a development project results in an accessible product• launched in March 2006, broadly welcomed by UK site owners © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • The one constant on the web is change…• PAS-78 needed updating to handle: – web 2.0’s much wider purposes for websites, including: • the move from informative web content to: – web as tools (“Software as a Service”) – web as rich/media-media entertainment (games, IPTV, eLearning etc.) • the move from Provider-Produced content, to User-Generated content (blogs, Facebook etc.) – increasing number of devices on which websites are viewed: • mobile phones, tablets, IPTV… – increasing use of non-W3C technologies – Increasing use of “off the shelf” tools rather than bespoke development © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • How we created BS8878• 3 year’s work• Created by accessibility experts on IST/45 from: – BBC, Lloyds Banking Group, Nomensa, Open University, JISC, Pinsent Masons, University of Southampton, British Computer Society, COI, IBM, RNIB, United Response, Opera, AbilityNet, Vodafone, RNID• Reviewed publicly by: – 328 experts from the UK and worldwide – Including: W3C, Adobe, experts in personalisation, aging, mobile, IPTV, inclusive design, user research and testing, disability evangelism… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • BS8878 – setting the sceneTalking about web productsOrganizational responsibility and policyPer product rationale – considering options, justifying reasoning, notingdecisions; all in an accessibility policyCommunication of those decisions © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Preamble: why “web products…”? – not just websites but also workplace apps, RIAs, SaaS, widgets, mobile apps – not just web on a computer any more… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Organizational:the importance of responsibility and BAU policy – work out whose responsibility web accessibility is going to be in your organisation… – get them to look at the business reasons why this is important… • check out OneVoice business cases… – create an Organizational Web Accessibility Policy to embed accessibility into the organization’s business as usual • may include where accessibility is embedded in: – web procurement policy – web technology policy – web production standards (e.g. compliance with WCAG, browser support, AT support) © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Per product:making good decisions, at each stage of the process• every decision taken will affect whether the product will include or exclude disabled and elderly people• so every decision should be: • recognised as a decision • have all options and implications considered • made based on justifiable reasoning • noted in the product’s accessibility policy for transparency• for every step of the production process © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Per product:communicating your decisions…• to the user… Why – through the product’s accessibility that choice? statement, published as part of the product• to check conformance with BS8878… – conformance requires: • address all the recommendations • justifying any course of actions that deviates from these recommendations • checking the decision processes in the product’s accessibility policy to provide evidence of following the recommendations © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • First stage: doing the right research &thinking before you start… 1. Define the purpose of the product 2. Define its target audiences 3. Analyse the needs of the target audiences for the web product 4. Note any platform or technology preferences and restrictions 5. Define the relationship the product should have with its audiences 6. Define the user goals and tasks the web product needs to provide © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 1. Define the purpose of the web product – without knowing this, you don’t have a basis for sensible decisions… – web 2.0’s much wider purposes for websites, including: • the move from informative web content to: – web as tools (“Software as a Service”) – web as fun/entertainment (games, IPTV) • the move from Provider-Produced content to: User-Generated content (blogs, Facebook etc.) – the challenges and costs of making products with different purposes accessible can vary hugely, eg: • costs of subtitles, audio-description for video • can 3D experiential games be truly made accessible? • whose responsibility is it to make UGC accessible? © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 2. Define its target audiences• can you • is it designed for a • or will be used by a predict/control who particular audience? range of audiences? will use it? – e.g. an Intranet – or an extranet © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 3. Analyse the needs of those audiences for the product – questions: • what are their general needs from the user experience of a web product? • do they have specific needs from the product? – how are you going to research these needs? • general desk research into • your own research – surveys, ‘disabled people’s use of the web’ ethnographic research into the context, preferences and specific product needs of your audiences – like you might do for non-disabled audiences… – resulting in personas etc. © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 4. Note any platform or technology preferences/ restrictions – for example: • lack of ability to download & install plug-ins or browser updates • IT policy restrictions in offices, colleges preventing use of browser preferences, installation of assistive technologies • strong platform preferences due to worries of cost/complexity/security – will impact on technology choice, platform choice, reliance on ATs to mediate website experiences • cf. rich-media technologies like Flash and ‘alternative versions’ • accessibility isn’t about luddite-ism, but it is about understanding what your audience really need… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 5. Define the relationship the product should have with itsaudiences – optimising your product’s relationship with its target audiences… – is the product going to consider its audiences to be: • individuals (incl. personalisation functionality, via logins or cookies) • more general groups of users – impacts on whether the audience may expect an ‘inclusive’ or ‘personalised’ accessibility approach © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 6. Define the user goals and tasks the web product needs toprovide – what goals are your audiences going to come to your product to achieve? – are there specific goals which are more important to your different audiences? – what goals are core, and what are not? • e.g. on iPlayer: finding and playing a programme is core… being able to share it with your friends might not be… – how will you define your product is successful in enabling its target audiences to achieve these goals? © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Second stage: making strategicchoices based on that research 7. Consider the degree of user-experience the product will aim to provide 8. Consider inclusive design and user-personalized approaches 9. Consider the delivery platforms to support 10. Choose target browsers, OSes and ATs to support 11. Choose to create or procure the product, in-house or contracted-out 12. Define the web technologies to be used in the web product © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 7. Consider the degree of user-experience the product will aimto provide – degrees: • technically accessible • usable • satisfying/enjoyable – an example for online Pacman: • Technically accessible = can control Pacman using a switch • Usable = have a chance of winning as the ghosts adapt to the speed of interaction of my switch • Satisfying = have the right level of challenge – not too easy or too hard – define the aim for each combination of user group and user goal – BS8878 doesn’t tell you what level you should pick, just lets you know what the options are, and asks you to choose a level you feel you can justify © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 8. Consider inclusive design & user-personalized approaches (1) – non-individualized/inclusive • accessibility through guidelines, inclusive design, ATs, user-testing… – user-personalized allows… • users to specify their needs and then… – finds a suitable product from a number of alternative versions, or – adapts the web product to those needs • often through ‘additional accessibility measures’ – circumstances where a personalised approach could be useful: • where a ‘one size fits all’ approach doesn’t work for all your target audiences • if individual relationship with audience is possible/expected (e.g. eLearning) then a personalised approach might be expected • for audiences with restrictions on browser, installation etc. – user-personalized should always complement, never replace, inclusive design approaches © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 8. Consider inclusive design & user-personalized approaches (2) • an example of user-personalized approach: BBC MyDisplay (coming soon) © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 9. Consider the delivery platforms to support (1) – Remember… not just web on a computer any more… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 9. Consider the delivery platforms to support (2) – With different screen sizes… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 9. Consider the delivery platforms to support (3) – And input devices… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 9. Consider the delivery platforms to support (4) – And different capabilities… XHTML WAP CSS Browser options ATs MHEG © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 10. Choose target browsers, OSes & ATs to support – what are you going to do about handling accessibility across browsers, OSes and ATs? – the less you have to support, the cheaper… • each browser has its quirks… • and different screenreaders can require lots of testing and code workarounds… – how to decide… • do you have any ability to control/standardise the browsers, OSes and ATs your target audiences will use? – this is do-able for an intranet or extranet, but not for a public site • if not, how many of the combinations of browser, OS and AT that are available on your supported platforms is it reasonable to support? – what’s used by your audiences? – is it reasonable to ask your audiences to change browser, OS or AT? • can you use user-personalised approaches like additional accessibility provisions or alternatives to get around restrictions? © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 11. Choose to create or procure the product, in-house orcontracted-out – are you going to create the product in-house, or contract out its creation – are you going to create the product from scratch, or by selecting and integrating tools, software, components or services • if contracting out, how do you ensure that the supplier is able to deliver to the accessibility requirements and aims for the product? – checking out their capabilities – ensuring the contract includes the requirements and aims from your accessibility policy so far © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 12. Define the web technologies to be used – what underlying technologies are you going to use to create the web product? • if creating the product bespoke, • if you are selecting and how do you ensure the integrating other tools, technologies you use will create a components or services, how do product which is accessible? you ensure that they will allow the – whether the technology supplies creation of an accessible techniques for WCAG 2.0 product? – whether the technology exposes – putting these considerations in content, structure and the selection criteria functionality to assistive – especially ensuring any authoring technologies on the platform tool is ATAG compliant © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • Third stage: production, launch andmaintenance (lifecycle) 13. Use web guidelines to direct accessible web production 14. Assure accessibility through production 15. Communicate accessibility decisions at launch 16. Plan to assure accessibility in all post-launch updates © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 13. Use web guidelines to direct accessible web production – the bit everyone knows… – using the best accessibility guidelines for the platform and technology being used… – including a choice on conformity levels, where they exist… – the complications: • this isn’t just WCAG 2.0… (although that’s the basis…) • what about mobile? • and IPTV? • and what about older people – are their needs the same as disabled people’s? – BS8878 here is a guide to what guidelines are appropriate in each of these cases © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 14. Assure the product’s accessibility through production Quality of data – creating an accessibility test plan • which testing methods will be used… • at what points of the production User testing process… Remote testing – sticking to the plan User reviews / interviews – when the ideal isn’t possible… Expert walkthrough Heuristics making the decision – is it ready to Testing with assistive technologies launch? Automated testing • how much accessibility risk are you Cost happy to accept for launch? • any mitigating factors? (workarounds, post-launch fixes) – how to communicate imperfect aspects to audiences at launch © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 15. Communicate accessibility decisions at launch – communicating all those decisions to your audiences… – in an easily found accessibility statement on your website – which your audiences can understand… Confusing help text: A number of sites  accessed by participants provided help  pages which were so technical that they  were practically useless. Mention of  plugins and cookies resulted in  complete confusion by the users and  apprehension about whether they were  able to follow the instructions given. © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • 16. Plan to assure accessibility in all post-launch updates – include post-launch accessibility monitoring in your test plan, to ensure: • updates to the product improve or uphold its accessibility • updates to your target audiences’ assistive technologies improve or uphold its accessibility – ensure all audience feedback re the product’s accessibility is reviewed and dealt with well • how to ensure your audience let you know their thoughts • and how to deal with them… – ensure the product’s accessibility policy and statement are updated to reflect this… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
    • BS8878 – next stepsIST/45 want your feedbackJoin the BS8878 Community of Practice to give feedback, discuss etc.Any other questions… © jonathanhassell@yahoo.co.uk http://www.meetup.com/bs8878-web-accessibility/
