<p>PURPOSE:To provide a three-dimensional coordinate input device capable of operating a coordinate input without limiting operation space and a cursor display control system expressing selective operation, etc., of a subject on a picture according to the perspective of a distance of a displayed pointer cursor. CONSTITUTION:The three-dimensional coordinate input device 10 is constituted of speed sensors 11-13, integration circuits 14-16 outputting a signal showing displacement and coordinate value calculation means 17-19 in respective directions of a depth axis, a horizontal axis and a vertical axis. A cursor display control means 20 is constituted of a cursor shape control part 21 deciding the shape of the pointer cursor from the coordinate value of the depth axis, a shadow shape control part 22 deciding the shape of a shadow added to the pointer cursor from the coordinate value of the depth axis, a cursor position control part 23 and a shadow position control part 24 deciding the display positions of the pointer cursor and the shadow on the picture.</p> |
