Google’s Sergey Brin gave a Ted Talk late last month and it was summarized thusly:
“This act of looking down at my phone is one of the reasons behind Glass. We questioned whether you should be walking around looking down. That was the vision behind Glass and that’s why we created this form factor. (…) When we made this we thought, ‘Can we make something that frees your hands and frees your eyes.’ That’s why we put the display up high and out of your line of sight so you can make eye contact with people. The sound conducts through the bones in your cranium to free up your ears. If you want to hear it better you cover up your ears, which is surprising. Our original vision at Google was eventually to get rid of the search query and you’d just get the information you need when you need it. Fifteen years later this is first form factor that delivers on that vision. The project has lasted just over 2 years. We’ve learned lot.”
