Abstract: A line-of-sight input device includes a line-of-sight identification section that identifies a line of sight of a user, a reference setting section that causes a storage section to store, as a reference line of sight, the line of sight being identified when the user is looking at a reference position in a display fixed to the head of the user; a display control section that causes the display to display a partial region of an entire region representing input elements that can be inputted, and changes a position of the partial region in the entire region, the partial region being displayed to the display on the basis of a relationship between the reference line of sight and the line of sight; and an input receiving section that receives an input of an input element positioned in a region including the reference position within the partial region displayed on the display.

Abstract: The present invention enables information associated with a person who provided a business card to be acquired when a user stores the business card in a business card case. A business card management system according to an aspect of the present invention includes a business card case, and a business card management apparatus, wherein the business card case includes an accommodation part that is capable of accommodating a plurality of business cards in a stacked manner, and a reading part that reads an image of a business card accommodated in the accommodation part, and the business card management apparatus causes a display to display additional information related to character information acquired from the image of the business card read by the reading part.

Abstract: A line-of-sight input device includes a detection means that detects a point of gaze or an eyeball rotational movement of the user, a movement control means that moves the input element; and an input determining means that determine an input of the input element near a predetermined position when a predetermined condition is satisfied; wherein the movement control means increases a movement speed of the input element as the point of gaze is farther from the predetermined position or a rotation angle of the eyeball rotational movement is larger, and makes the movement speed closer to zero as the point of gaze becomes nearer to the predetermined position or a rotation angle of the eyeball rotational movement becomes smaller.
