Yesterday, a hyped-up video came out by Google on Project Glass.
Basically this is Star Trek-type glasses that provide everything that's on your smartphone plus some augmented reality, where real world sensation is augmented with computer-generated information.
The video shows the glasses integrated with functionality for email/messaging/phones calls, photos/videos, music, reminders, weather, maps/directions, transportation updates, and more.
Aside from the integration into the glasses themselves, they really didn't demonstrate any major new technologies--and was sort of disappointing actually.
It reminds of Google+, which came out and didn't add anything much new over FaceBook, and hence hasn't really caught on--copycatting just isn't enough in the high-tech industry, where real innovation is what's valued.
While I like the idea of more and better ways of getting the types of information and functionality that's on your smartphone, I really don't think glasses is the way to go.
Frankly, after having LASIK surgery more than 12 years ago, I am so happy not to have to wear those obtrusive frames on my face anymore, and I certainly wouldn't want to go back.
I would envision having these functions either built microscopically into contact lens or projected by mini-wearable cameras in front of you as a true reality overlay--and I think Minority Report thought of that one first.
The only way that I would even consider wearing glasses for this was if Apple made them and called them iGlasses. ;-)
