The accuracy of the current system allows to estimate the pointing target to an accuracy of 2 cm in a workspace area of 50×50 cm. The system consists of several neural networks that perform the tasks of image segmentation, estimation of hand location, estimation of 3D-pointing direction and necessary coordinate transforms. Drawing heavily on the use of learning algorithms, the functions of all network modules were created from data examples only.
