Abstract: An apparatus for controlling the position of a screen pointer for an electronic device having a display screen includes an imaging surface against which a portion of the tip of a human digit may be placed. A light source illuminates that portion of the tip of the digit that is placed against the imaging surface, thereby generating reflected images. The apparatus includes a motion transducer. A lens receives the reflected images and directs the reflected images onto the motion transducer. The motion transducer generates digital representations of the reflected images. The motion transducer generates a first set of movement data based on the digital representations of the reflected images. The first set of movement data is indicative of motion of the tip of the digit across the imaging surface. A controller generates a second set of movement data when the tip of the human digit is removed from the imaging surface. The second set of movement data is indicative of motion of the tip of the digit across the imaging surface prior to removal of the tip.

Abstract: A method and system for tracking attitude of a device (10) includes fixing a two-dimensional array (16) of photosensors to the device and using the array to form a reference frame (202) and a sample frame (206) of images. The fields of view of the sample and reference frames largely overlap, so that there are common imaged features (204) from frame to frame. Sample frames are correlated (42) with the reference frame to detect differences in location of the common features. Based upon detection of correlations of features, an attitudinal signal indicative of pitch, yaw, and/or roll is generated. In the preferred embodiment, the attitudinal signal is used to manipulate a screen cursor of a display system (72), such as a remote interactive video system (RIVS). However, attitudinal tracking using the invention may be employed in other applications. Another aspect of the invention is that the two-dimensional array (226) is configured to compensate for any curvilinear distortions introduced by a lens system (26) for imaging the features within the field of view of the array.
