ListLens

ListLens is a grocery list that lives in your Meta Ray-Ban Display glasses and checks itself off. Shopping with a list on your phone leaves no free hand: basket in one, phone in the other. With ListLens you pick something up, drop it in your basket, and it's crossed off on the display in front of your eyes. The glasses stream their camera to the iPhone. Muse Spark looks at each frame with your list and says what you're holding, whether it's going in the basket, and which item it matches. A cart watcher on the phone turns those answers into check-offs, and the list is redrawn on the glasses. Open source (MIT). Built entirely during the hackathon.
