Abstract
A method for evaluating gestures based on data of a sensor having lateral drift-field photodetector diodes (LDPD) diodes, the method includes sequentially measuring first, extraneous light in order to obtain two dimensional (2D) data in the form of reflectance data; measuring second, laser light in order to obtain three dimensional (3D) data in the form of distance data; measuring third, residual light; obtaining movement artifacts in the 2D and/or 3D data which were caused by residual charges in a moved object; detecting a movement by processing the movement artifacts; and evaluating the detected movement with regards to a possible gesture.
