Abstract: A display system and method for use in controlling movement of a virtual image version of a physical object is described. A physical object may be placed on or near a display surface, which may sense the presence of the object and display a virtual image version of the object.

Movement effects, such as blurring, fading, animation, etc. may be applied to the image during the movement. The movement may change direction as the physical object is detected in different positions, and the movement effects may be applied to smooth the change in direction (e.g., curving trajectory).

Abstract: An optical mouse system with an illumination guide includes a concave lens for spreading light to create a uniform, low contrast, illumination pattern. The uniform illumination pattern increases the accuracy of mouse movement detected by the sensor. The illumination source and optical sensor are mounted in the same plane, directly on the PCB. The higher angle of the optical path causes more light to be reflected to the optical sensor, increasing optical efficiency and allowing a smaller, lower powered LED to be used. This also results in increased sensitivity of the optical sensor. Lower power usage increases battery life for mobile or wireless-mouse use, while reducing thermal waste considerations. This allows the creation of a significantly smaller form factor for the overall package, thereby reducing materials costs and giving designers more flexibility for external design considerations.
