Abstract
An eyeball movement detection device () detects an eyeball movement of an eye in a side-to-side direction on the basis of a time shift in difference between an output from a far-infrared sensor () having directivity to an edge of an exposed surface of an eyeball on the side of the inner corner of the eye and an output from a far-infrared sensor () having directivity to an edge of the exposed surface of the eyeball on the side of the outer corner of the eye. This makes it possible to detect an eyeball movement in a noncontact manner, with a light weight, and with low power consumption.
