LINE-OF-SIGHT-BASED CONTROL DEVICE AND MEDICAL DEVICE

The present invention provides a line-of-sight operation-apparatus, a method, and a medical device by which it is possible to appropriately determine whether a movement of a line-of-sight is intended by a user and to prevent the user from being forced to carry a burden. The line-of-sight operation-apparatus includes a display screen, a display control unit to display an icon having an animation-image on the display screen, a line-of-sight detection unit that detects a line-of-sight of a user, a following determination unit that determines, on the basis of a result of detection performed by the line-of-sight detection unit, whether a movement of the line-of-sight of the user follows a movement of the animation-image, and an output unit that outputs information indicating that the icon has been selected in the case where the following determination unit determines that the movement of the line-of-sight of the user follows the movement of the animation-image.
