For Voss, Wall, and their colleague Nick Haber, a Stanford post-doc, the idea is that their Glass software will help autistic children recognize and understand facial expressions and, through them, emotions. It operates like a game or, as Voss calls it, an “interactive learning experience.” Through the Google Glass eyewear, children are asked to, say, find someone who is happy. When they look at someone who is smiling, the app recognizes this and awards “points.” The system also records what the child does for later review. “You can plot, as they wear the glasses, how they’re improving, where they’re improving,” Wall says. “You can look at video to understand why.” READ MORE: Clinical Trial Will Test if Google Glass Can Help Kids with Autism | WIRED
