Abstract:
An optical navigation device is provided for detecting movement of a pointer, such as a finger, in three dimensions. A sensor obtains images of the pointer which have been illuminated by an illumination source, and an image scaling module determines the difference in size between images acquired by the image sensor to determine the difference in height of the pointer between images.
