Abstract
Apparatus for information input to a computing device including imaging sensors arranged to simultaneously view an input region and enhanced triangulation signal processing circuitry receiving signal outputs from two of the imaging sensors, which signal outputs contain information indicating an angular position of an object relative to each of the two imaging sensors and information representing angles respectively subtended by the object with respect to each of the two imaging sensors, useful for indicating a relationship between the angles respectively subtended by the object with respect to each of the two imaging sensors, the enhanced triangulation signal processing circuitry providing an object location output based not only on the information indicating an angular position of the object but also on the relationship between the angles respectively subtended by the object.
