Abstract
A visual axis input and decision transfer device operates so that when a detection-result condition, such as a visual-axis-detection success or failure, blinking, selecting of the same choice, or the like is judged based on visual-point-position data, and a user is notified of detection-result information indicating the detection-result condition in response to a judgment result by changing a selection frame color of characters, the user can confirm the detection result of the visual axis, and is prevented from repeating wasteful operations many times.
