CONSTITUTION:This device is provided with a display part 10 having a screen presenting visual information, a visual point position estimating part 16 which estimates the user's visual point position on the screen based on presented visual information, an eyeball motion detecting part 17 which detects the direction of user's eyeball, and a sight direction calculating part 15 which calculates the visual point position on the screen based on the direction of the eyeball detected by the eyeball motion detecting part 17 and the visual point position estimated by the visual point position estimating part 16. The visual point position estimating part 16 estimates the visual point position by the distance between the user and the display part 10.</p> |
