Eye-gaze measuring system, eye-gaze measuring method, and program

摘要

A line-of-sight measuring system according to the present invention is provided with an user imaging unit wearable by an observer who moves in a display space displaying an object to be observed, capturing a field view image in front of the observer; an user line-of-sight measurement unit wearable by the observer, acquiring a line-of-sight measurement data showing a line-of-sight direction of the observer relative to a coordinate system of the field view image; and a line-of-sight measurement apparatus obtaining a gaze point at which the observer in the display space gazes, in accordance with a coordinate position at which a three-dimensionally shaped data in the display space crosses a line-of sight direction vector of the observer in the display space, the three-dimensional data including the object to be observed, and the line-of sight direction vector being obtained from the line-of-sight measurement data.
