I am sure that there are many interested in both academia and industry! The possible uses and extensions for these visual aids are too many to list and I would not be far-sighted enough to give a proper list. I think that we will be wearing more rather than less tech in the future. Consider auto-darkening glasses, HUD car dashboards, the explosion of iPhone/Blackberry handhelds; these will only get smaller and be better integrated with the users in the future.
The field testing will only can bring the usability of this system. Many times users find it difficult to use these kind of items. After practicing it for a month or so they become comfortable. It is like wearing spectacles newly and adjusting it with it.
It would be good to see images of what a person wearing it would see. This must be a multidisciplinary development. I wonder how the project was supported or sponsored? Who's interested in this from the academia or industry?
And, on other end, are we in the future going to be using this kind of glasses? We'll we become used to wear-tronics?
