Earlier this week I watched the video (below) that Google released demoing some of the uses for Google Glass.
This experimental project, which you can apply to test for $1,500 USD, is a cool little wearable device in the form of glasses that have a variety of uses.
I was very excited when I saw this video, then I realised the underlying interface technology for most of the video was voice recognition. I have had experience with voice recognition from Apple (Siri), Nuance (Dragon Dictation) and Google (Voice Search) and the one thing they all have in common is how often they misinterpret what you are trying to say. While I really like the idea of Google Glass, substantial improvements to voice recognition would be needed before such a product could ever be useful.
