1. A gaze detection apparatus comprising:
a gaze detection section that detects gaze of a target person; a display section that includes a display screen for displaying an image; a first gaze position determination section that operates to determine whether or not the display screen lies in the gaze of the target person based on a result of detection by the gaze detection section; a first display control section that operates to display a first detection result image at an intersection point between the gaze of the target person and the display screen when the first gaze position determination section determines that the display screen lies in the gaze of the target person, wherein the first detection result image is a preset image and indicates the result of detection of the target person's gaze, wherein the first detection result image moves accordingly with the gaze of the target person, the first display control section further displays an allowable error indication image that indicates a range of an allowable gaze detection error of the gaze detection section, and a center of the allowable error indication image is at a display position of the first detection result image, the gaze detection apparatus further comprising: a first gaze movement detection section; a first prohibition section, wherein after the first display control section displays the first detection result image, the first gaze movement detection section determines whether or not the gaze of the target person is moved equal to or more than a preset fixing display determination distance based on the result of the detection by the gaze detection section, and when the first gaze movement detection section determines that the gaze of the target person is moved equal to or more than the preset fixing display determination distance, the first prohibition section performs a first prohibition operation which prohibits the first display control section from operating; a second gaze position determination section that determines, based on the result of the detection by the gaze detection section, whether or not a screen-outside displayable region lies in the gaze of the target person, wherein the screen-outside displayable region is a preset region surrounding the display screen; a third display control section that displays a third detection result image at a particular place when the second gaze position determination section determines that the screen-outside displayable region lies in the gaze of the target person, wherein the particular place is on an outer edge of the display screen and is set in a vicinity of an intersection point between the gaze of the target person and the screen-outside displayable region; and a guidance display control section that displays a guidance image on the display screen after the third display control section displays the third detection result image, so that
the guidance image is located on an opposite side of the third detection result image from the screen-outside displayable region, andthe guidance image guides the gaze of the target person into the display screen. |
