Doyle, whilst this snippet* is still text it has the additional benefit that it is rendered as a specific representation that maybe tested. It would be great if you could illustrate some of your discussion. Doyle wrote: We don't want an icon in my view to look like an object we want an icon to stick to a sparrow in such a way that it touches all birds and we know that. That is what written words do. They stick to an object they don't resemble the object. That resolves what you referred to in the example of the red bus and green bus, is the connectedness issue between expressions such that the green and red refer to the same bus. Unfortunately this is the nub of the issue, and it is far from resolution. People with SLD simply don't generalise or abstract in the way described, one might go so far as to say that this is one definition of a LD. Naturally if we could find an abstract pointer the issue would be resolved, but we can't. So this leads to much confusion, little of which is resolved by text based discussion. Doyle wrote: We want to build in a connection process. Reality fortunately has many useful pointers, loo signs for instance. However these are currently missing in virtuality, and so for the present it is necessary to augment virtuality, before it will help augment reality, the HUD has to highlight the pylon before the pilot can avoid it. Sadly peepo is very nearly a lone voice in the area of providing a W3C accessible virtual space, even though in a very limited sense. However there are many excellent VRML, flash and other attempts. Accessible SVG is also an extremely rare commodity :-( to resolve the red bus problem will also require excellent and transparent authoring tools. Perhaps we can use your expertise to create some other useful visual examples with SVG.
