Title:
VIDEO ANALYSIS DEVICE, VIDEO ANALYSIS METHOD, AND POINT-OF-GAZE DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/175701
Kind Code:
A1
Abstract:
A video acquisition unit (310) acquires, from two light sources, a first light source (220) which moves in conjunction with a movement of a user's head part, and a second light source (400) which has a location which is invariant in relation to a video presentation unit (500) which the user treats as an observation object, a video of a region including reflected light from each respective light which is illuminated on one of the user's eyeballs, which an image capture element (210), which moves in conjunction with the movement of the user's head part, has image captured. A head part movement estimation unit (320) estimates the movement of the user's head part on the basis of the relative location of the reflected light of the second light source (400) to the reflected light of the first light source (220) in the video which the video acquisition unit (310) has acquired.
