Eye movement detection apparatus and eye movement detection method

摘要

PROBLEM TO BE SOLVED: To suppress a noise component getting mixed in eye potential data due to shaking of the head of a user when the user wearing an eyewear with an Electro-Oculography (EOG) electrode walks.SOLUTION: An eyeball motion detection device according to one embodiment is used in a form of an eyewear-type device. The eyeball motion detection device comprises: an EOG electrode to detect eyeball rotation of a user wearing the eyewear; an acceleration sensor to detect movement of the eyewear; and a gyroscope sensor to detect rotation of the eyewear. The eyeball motion detection device detects the eyeball rotation and at the same time movement and rotation of the user's head when the user wearing the eyewear walks while watching a fixed object in an actual world. Then, the eyeball motion detection device cancels out (reduces or eliminates) noise getting mixed in eye potential when the user watches the fixed object in the actual world while the user's head is moving by synthesizing signal components (components that is in an opposite phase to the mixed noise) corresponding to the movement of the head detected by the acceleration sensor and/or the gyroscope sensor.SELECTED DRAWING: Figure 17
