Abstract
A system for predicting a touch position of a pointer on a touch-enabled unit includes a 3D imaging unit, a processing unit coupled to the 3D imaging unit, and a touch-enabled unit coupled to the processing unit. The 3D imaging unit is configured to monitor an interaction zone in front of the touch-enabled unit. The processing unit includes a prediction module that is configured to predict where a pointer that approaches the touch-enabled unit and is monitored by the 3D imaging unit will touch the touch-enabled unit, and a calibration module that is configured to generate at least one calibration parameter by comparing the predicted touch position to the actual touch position of the pointer detected by the touch-enabled unit and to transfer the at least one calibration parameter to the prediction module in order to calibrate the prediction module.
