Optical location tracking devices |
摘要 |
A practical location tracking device provides cost-efficient methods for inputting three-dimensional location information. This device comprises light sources and light receiving elements. Each light receiving element comprises two or more closely spaced planar light detectors with their light receiving surfaces facing different spatial directions. Three dimensional location is determined by comparing the relative light intensities detected by those light detectors.
