摘要： A computer-readable recording medium storing a displacement determination program is disclosed. First and second face areas of a person are extracted, respectively, from first and second images captured by first and second imaging devices arranged at certain positions where first and second available ranges for detecting a gaze are overlapped. First and second feature points are detected based on light reflections in the first face area and the second face area being extracted. First and second gaze positions of the person are calculated based on the first and second feature points being detected. An arrangement displacement is determined from both or one of the certain positions of the first and second imaging devices based on a relative position relationship between the first and second gaze positions.

摘要： A detection system for detecting an eye gaze of a subject includes an image sensor configured to generate an image by capturing reflected light from a subject side irradiated with light from a light source; and a processor. The processor is configured to extract a region from the image, the region having an intensity of the reflected light which is equal to or larger than a specific value, when there are two or more regions, as a extraction result of the region, in which a first region having a characteristic indicating movement over time coexist with a second region having another characteristic indicating no movement over time, determine the first region as a corneal reflection, and detect the eye gaze of the subject based on the corneal reflection.

摘要： A tablet terminal receives a triggering indication to enable a detection result of eye gaze, and sets a target area in which the presence of a target object is assumed on a screen of a touch panel using a detection position of eye gaze. The tablet terminal further displays a partial image displayed in the target area out of an image displayed on the screen in an aiming area in which a touch operation to the target area is received in place of the target area, and records a correspondence relation between coordinates of the aiming area and coordinates of the target area. When a touch operation is received within the aiming area, the tablet terminal converts the coordinates of the aiming area in which the touch operation is received into the coordinates projected to the target area using the correspondence relation recorded, and then outputs the converted coordinates.
