Abstract
An electro-oculography estimating device includes: a distance obtaining unit which obtains a right-eye corneal distance, a right-eye retinal distance, a left-eye corneal distance, and a left-eye retinal distance; and an electro-oculography theoretical value calculating unit which calculates an electro-oculography theoretical value generated at the given three-dimensional positions, based on the right-eye corneal distance, the right-eye retinal distance, the left-eye corneal distance, and the left-eye retinal distance that are obtained by the distance obtaining unit, as an input into an electro-oculography model that is a function for calculating the electro-oculography theoretical value generated in the given three-dimensional spatial position, based on the right-eye corneal distance, the right-eye retinal distance, the left-eye corneal distance, and the left-eye retinal distance.
