Embodiment Construction
[0031] The exemplary embodiments described herein provide details regarding systems and methods for determining the position of one or more radiation blocking objects relative to various radiation sources and radiation sensors. In some embodiments, the radiation sources and sensors may be mounted in a frame. In some embodiments, the system may include or be used with various underlying devices, such as whiteboards, display monitors, and other devices. In some embodiments, the system may include or be used on an underlying surface, such as a whiteboard, wall, the surface of a display screen, or any other generally planar surface. The radiation source may emit radiation in the visible spectrum or other spectrum such as the ultraviolet or infrared spectrum. The embodiments described herein are exemplary only and other implementations and configurations are possible.
