Abstract: Various mounting systems and methods for mounting position sensing systems about a sensing region are described. The mounting system includes mounting brackets for mounting system modules. The system modules include radiation sources and sensors that are used to estimate the position of a radiation blocking object about the sensing region. The mounting system may be modular and may be dimensioned to match the dimensions of a display modules that are assembled in a matrix to form a display screen having a display surface. All or part of the display surface defines the sensing region in such embodiments.

Abstract: 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.

Abstract: Two dimensional position sensing system and sensors for use in such systems are disclosed. The sensors incorporate linear array sensors having sensor elements and an aperture plate. Some embodiments include a radiation source that directs radiation onto some of the sensor elements. Other embodiments including radiation blocking objects that block radiation from reaching some of sensor elements. The direction or position of the radiation source or radiation blocking object may be estimated from the radiation incident on the sensor elements.

Abstract: Two and three dimensional position sensing systems and sensors for use in such systems are disclosed. The sensors incorporate linear array sensors and an aperture plate to block light or other radiation from reaching most elements of the sensors. A direction of a radiation source relative is determined based on illuminated sensor elements in each sensor. The sensors are combined in systems to allow the position of a radiation source to be estimated.
