Well, we are still big fans of being able to control things with the mind, but with the hat-sized-MRI-machine still months to years away, this may be the next best thing. Creator Manabe Hiroyuki has developed a machine that could eventually allow you to control things in your environment simply by looking at it.
A headphone-type gaze detector for a full-time wearable interface is proposed. It uses a Kalman filter to analyze multiple channels of EOG signals measured at the locations of headphone cushions to estimate gaze direction. Evaluations show that the average estimation error is 4.4® (horizontal) and 8.3® (vertical), and that the drift is suppressed to the same level as in ordinary EOG. The method is especially robust against signal anomalies. Selecting a real object from among many surrounding ones is one possible application of this headphone gaze detector.
