Three-dimensional information detecting device, three-dimensional information detecting sensor device, and three-dimensional information indicating device |
摘要 |
A three-dimensional information sensor device is disclosed in which sensor coils thereof are sequentially selected by a control section; the transmission/reception of signals are performed between the indicating coils of a three-dimensional information indicating device and sensor coils by electromagnetic coupling; the signal received by each of the selected coils are detected by detecting section; and the position and the direction of the indicating device in a three-dimensional apace are calculated by the control section, based on the detection signals detected. <IMAGE>
