摘要： Several systems for tracking one or more radiation blocking objects on a surface are disclosed. At least three radiation sensors are provided adjacent the surface and a plurality of radiation sensers are provided adjacent the surface. Radiation from at least some of the radiation sources can reach each of the radiation sensors. One or more radiation blocking objects on the surface attenuate radiation from one or more radiation sources from reaching each of the sensors. One or more polygons is calculated based on the attenuated radiation sources and the positions of the sensors. The position of the one or more radiation blocking objects is estimated and may be tracked based on the polygons.

摘要： Several system for tracking one or more radiation blocking objects on a surface are disclosed. At least three radiation sensors are provided adjacent the surface and a plurality of radiation sources as provided adjacent the surface. Radiation from at least some of the radiation sources can reach each of the radiation sensors. One or more radiation blocking objects on the surface attenuate radiation from one or more radiation sources from reaching each of the sensors. One or more polygons is calculated based on the attenuated radiation sources and the positions of the sensors.
