I think that this raises an important point about inclusion of accessibility features: they are often very innovative, and they enhance the experiences of average users. For example, the on-screen keyboard can be adapted for use on touch-screen devices (at least this is my understanding from discussions I had with Nohemi Fernandez while we were in Montreal) - as long as someone extends the code :) Since the trends right now are moving away from mouse use, it might be helpful/interesting to ask ourselves whether or how cameras can be used to replace them. Are there situations in which a camera would be more useful than a touch screen or track pad? Certainly it can be for certain users with disabilities, but we might want to explore other use cases, as well. > > > > > I -think- that for this to work properly we'd need a bunch of things: > > first, we need to track not only head movement but also your eyes and > > several facial muscles so that we can have accurate tracking and hints > > about your > > AFAIK, eViacam developers plans to add support for more facial gestures > in the future. > > > intentions.
