A section detection section that detects the section, a viewpoint position detection section that detects the user's viewpoint position within the section, and a movement amount that converts the viewpoint movement amount into the cursor movement amount on the screen using the output of this viewpoint position detection section as input. A converting section, a cursor moving section for moving a cursor on the screen by inputting the output of the section detecting section and the output of the movement amount converting section, and an instruction means for giving an instruction, the cursor moving section and the instruction means The output is used to select and instruct items for instructing operations on the screen.

[0008]

[Operation] In the input device having the above-mentioned structure, the section detecting section first detects one section on the screen from among the plural sections divided by the dividing means in order to limit the range on the screen. Next, the position within the selected section is detected as the user's viewpoint by the viewpoint position detection section. Since the user's viewpoint is detected only for the section specified by the section detection section, processing data is small. This simplifies the circuit configuration and makes it easier to calibrate to improve accuracy, so the cursor can be moved to the exact position on the screen that a person expects in any usage situation.
