摘要： A system and method for tracking the x, y and z coordinates of a position of an input device in an interactive computer system is disclosed. An image sensor situated on the input device captures images of an electronic marker displayed on a display screen. As the position of the input device changes, the features of the electronic marker as captured by the image sensor also change. Images of the electronic marker captured during game play are compared to a calibration image of the electronic marker to determine current x, y and z coordinates of positions of the input device. The game display is updated to reflect the movements of the input device.

摘要： A pointing device and method for operating the same is disclosed. The pointing device includes an illumination system, a camera system, and a controller. The illumination system illuminates a surface over which the pointing device moves. The illumination system generates a light level determined by an illumination control signal. The camera records a plurality of images of the illuminated surface. The controller records first and second images taken by the camera at different times and determines a displacement indicative of the direction and distance the positioning device moved between the two different times. The controller also generates the illumination control signal. The illumination control signal depends on at least one of the images recorded by the camera system. In one embodiment, the surface is characterized by a reflectivity and the light level generated by the illumination system is inversely related to that reflectivity.

摘要： A pointing device, such as an optical mouse, includes a light unit for illuminating a surface, a photodetector array configured to generate image information related to the illuminated surface, a navigation engine for generating navigation information at a target resolution of the pointing device, and a resolution input interface for controlling or adjusting the target resolution value of the pointing device via input of a resolution scaling ratio. The resolution input interface is configured for user input of the resolution scaling ratio, such that the target resolution of the pointing device can be readily adjusted, in real time, over a broad range of resolution values and in small increments. A technique for mitigating cursor jitter problems at high resolution values is also disclosed.

摘要： One embodiment in accordance with the invention relates to detecting a homogeneous surface. A first surface image is received. A plurality of values are generated by performing a plurality of auto correlations with the first surface image and a copy of the first surface image. The plurality of values includes a first peak value. A determination is made as to whether a normalized second peak value of the plurality of values satisfies a defined condition associated with a value. If so, a homogeneous surface image filter is utilized with a second surface image.
