I don’t have the EyeX yet, but I’m very curious as to how well the Tobii Windows Control will function.
Unless the EyeX is extremely more accurate than I imagine, I still think that the community will have to come up with some software features to select the smallest interface elements, like individual characters.
This is a crappy mockup of something I’ve been envisioning:
Generate/project large-button, touch/eye-tracking UI from existing non-touch/non-eye-tracking UI
Tag nearby elements w/ color & ID – project to large element (screenshot and mock-up)
