Abstract

Provided is a visual fatigue-measuring apparatus capable of accurately measuring a viewer's visual fatigue without interrupting the viewing of a three-dimensional video such as a game. The apparatus is equipped with: a video display unit (120) for displaying a three-dimensional video; a test interval-determining unit (190) that determines two or more time intervals for a test that measures visual fatigue; an eye movement-acquiring unit (200) that acquires data representing the left and right eye movements of a player (100) in response to a displayed video; an eye movement-extracting unit (220) for extracting, from the acquired data representing the eye movements, data representing the respective eye movements during the two or more time intervals determined by the test interval-determining unit (190); an eye movement-comparing unit (230) that compares the eye movements in the two or more time intervals on the basis of the extracted data; and a fatigue-assessing unit (240) that assesses the visual fatigue of the player (100) from the results of the comparison.

Description

technical field [0001] The present invention relates to a device and method for measuring a degree of visual fatigue for measuring a state of visual fatigue (degree of visual fatigue) of a player watching a three-dimensional video such as a game. Background technique [0002] 3D images are popularized not only in movies, but also as images for TV content and games as home TVs and computer monitors capable of 3D display become popular. Three-dimensional video creates the illusion of depth for the viewer by designing a parallax between the image presented to the right eye and the image presented to the left eye. According to such a three-dimensional video, it is possible to feel the depth more three-dimensionally, and to enjoy an exciting video with a more realistic sense, especially in a game, so that the player can enjoy it with more immersion. However, 3D images are considered to cause more visual fatigue than previous 2D images. One of the reasons is that although the li...
