Реферат: Several systems for tracking one or more radiation blocking objects on a surface are disclosed. A pair of radiation sensors are provided adjacent the surface and a plurality of radiation sources are provided adjacent the surface. Radiation from at least some of the radiation sources travels across the surface to 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. The position of the one or more radiation blocking objects is estimates and may be tracked based on the position of the one or more attenuated radiation sources relative to each radiation sensor.
