By the look of the Wearable Gaze Detector — with its many protruding wires and Cyberman-esqe design — it would have to do something pretty amazing to be worth committing the fashion felony of actually putting it on your head. Well, you see those rectangular thingies on top of each earcup? Those are tiny video cameras, each tracking your eye movements by detecting the changes in electrical potentials that happen when they move. The idea is the Gaze Detector would record everything you're looking at, so later on you could watch a movie of your day with an accompanying "attention marker" pointing out exactly what held your gaze. Paired with a Web browser, the program could automatically call up information on the objects you looked at. Saw a nice painting as you walked through a building lobby? Review the video and find out who's the artist. Caught a glimpse of a cool car? Call up its make and model and where you can get the best price. Creator Manabe Hiroyuki would obviously have to do a lot of work on the design to turn the gaze detector into something you'd actually want to wear, but the eye-tracking technology certainly catches our attention.
