The problem of User Interface is a difficult one. Some people buy programs which do everything via a wizard, which asks them simple questions in natural language and does all the work itself. Some people avoid those products and will only use products which are based on the model of your extreme example. Many people fall somewhere in between. As a specific example, Microsoft Word is popular with some people because it is easy to use and you don't have to think. It is popular with other people because it provides a powerful programming interface which can be used to make it into the word processor that the individual really wants to use. Some people curse it because it automatically formats text, or recognises HTML and does conversions. Other people pay the list price specifically to have those functions. If we specify too far one way or the other then we are doing a disservice to the users at the end of the process, and a disservice to manufacturers, many of whom use their user interface as a major part of product differentiation. It seems to me that this approach may be to the detriment of those with cognitive disabilities. I hope that review of the document by people with expertise in that area will give us a clearer picture of what the priorities really are. But it is not easy to reconcile the need for a simple interface with the need for complex control of extensive functionality. Different ways of doing this will be tried by different manufacturers, which will hopefully result in a diversity of browsers large enough that everybody can find one which suits their needs, or in browsers which are sufficiently configurable that they suit the needs of everybody. --Charles McCathieNevile - mailto:charles@w3.org phone:(temporary) +1 (617) 258 8143 http://purl.oclc.org/net/charles W3C Web Accessibility Initiative - http://www.w3.org/WAI 545 Technology sq., Cambridge MA, USA On Tue, 15 Dec 1998, Paul Adelson wrote: In response to Charles McCathieNevile: >>> I would be surprised if any major manufacturers did not provide simple interfaces to their products. <<< Rather than expecting / hoping developers will do what we think they should, we should provide clear guidelines. For the conscientious developers much of this will be 'low hanging fruit', but for others it will be a wake-up call. The group has discussed CSS for alternative table rendering and other complex processes that go well beyond fonts / colors. If we state that enabling CSS support for an alternate rendering style is what a UA needs to do, we are _not_ making a clear statement that the user shouldn't need to research and reinvent arcane stylesheet code if they want to implement that alternative. An extreme example: can a vendor who makes their source code available claim that their product is therefore 100% accessible and 100% flexible, because all it takes to meet specific needs is writing your own code? A developer once made a similar claim to me (that his product was compatible with all peripherals and major operating systems because you could buy the source code and re-write it however you wanted.)
