Abstract
A motion capture system includes a motion capture detecting device with sensor coils that are sequentially selected by a control section. Signals are communicated between respective input coils of input elements of an input device and the sensor coils by electromagnetic coupling. The signals received by each of the selected coils are detected by a detecting section. Three-dimensional coordinates and directions of each of the input elements are calculated by a control section so that the input elements become continuous, based on the detected signals by the detecting section.
