| Research Abstract |
In this study, we proposed and developed a wireless magnetic position sensing system that uses LC resonant magnetic markers (LC markers), which is considered as a useful candidate of an input device of fingers motion for a virtual environment. The measurement apparatus composed of multi channels A/D convertors, which has 32 simultaneous analog inputs at 4 MS/s per channel with 16-bit resolution, was constructed. According to evaluation result, the total capturing speed of the system was around 100 Hz (one capturing per second) for two markers detection under synchronized operation of 32 A/D convertors. In addition, the capturing speed are 53 Hz for five LC markers and 20 Hz for ten LC markers.
