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. Signals are communicated between indicating coils of a three-dimensional information indicating device and sensor coils by electromagnetic coupling. The signals received by each of the selected coils are detected by detecting means. The position and the direction of the indicating device in a three-dimensional apace are calculated by control means based on the detected signals.
