You mean like the Opti Grab? We learned a lot about blindness from having guardianship of our blind teenage nephew for a year. True, the ear piece would be the big benefit for him (though one eye was very slightly sensitive to light). Others at his school had varying degrees of low vision and might at least benefit from bright flashes of light. But the big gain would be something that describes his environment out loud. Blind people do still aim their faces toward things. And it's much better than a similar capability in a handheld device such as the iPhone or iPod Touch, because for the blind, orienting a handheld device correctly can be a major problem. We turned on the accessibility features for our nephew's iPod, but the thing would switch from landscape to portrait as he turned his hand slightly. Head-mounted is the way to go. And for the sighted, it will be great for games, as I found out from the prototype glasses I got: http://youtu.be/lQGpOibUsyo http://youtu.be/lQGpOibUsyo
