ABSTRACT:
There is a described a user interface device having first and second imaging means for forming first and second images of a three-dimensional zone from two different viewpoints, and image data generating means for generating image data corresponding to the first and second images. A processor determines the position of an object within the three-dimensional zone from the image data for the first and second images, associates the determined position with corresponding information and generates a data signal in accordance with the information corresponding to the determined position. In an embodiment, the user interface device is in the form of a virtual keyboard. In another embodiment, the user interface device is in the form of a tablet for handwriting recognition.
