PACK DEVICE, ITS SENSE TABLE DEVICE, COORDINATE POSITION DETECTION SYSTEM, COORDINATE POSITION DETECTION PROGRAM, AND ITS RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To collect the moving locus of a pack device including space information.

SOLUTION: The pack device 1 is constituted of at least three light emitting diodes 11 and a light emission control device 12 for emitting respective light emitting diodes 11 at prescribed time differences. A sense table device 2 comprises: an optical signal receiving part 21 for receiving light emission signals from the light emitting diodes to which IDs are respectively attached; and an operation part 23 for calculating three-dimensional coordinates from the light emitting signals by a three-point measurement principle and then calculates a rotational angle from the coordinate positions of the light emitting diodes 11 identified by the respective IDs.
