摘要： A pointing device and method for using the same to measure the motion of that pointing device over a surface is disclosed. The pointing device includes an illumination system, an imaging system, and a controller. The illumination system generates light in a plurality of wavelength bands and illuminates a surface below the pointing device with light from one of the wavelength bands. The imaging system records images of the illuminated surface. The controller selects the wavelength band used to illuminate the surface, compares first and second images recorded by the imaging system at different times when the surface is illuminated with that wavelength band, and determines a displacement indicative of the direction and distance the positioning device moved between the two different times.

摘要： An optical computer mouse has a support structure that can be moved across a surface. An illumination source that illuminates a region of the surface is coupled to the support structure. An imaging system in the mouse includes an optical sensor array that receives light from the illuminated region of the work surface and an image processor that receives data from the optical sensor array. The optical computer mouse may be switched between a navigation mode of operation, in which the image processor detects motion of the optical computer mouse over the work surface, and a barcode reading mode of operation, in which the image processor senses a barcode as the optical computer mouse is moved across a barcode.

摘要： An optical navigation device containing an adjustable depth of field light source is positioned with respect to a surface such that the depth of field of light source can be adjusted to match the Z dimension of a particular surface. In one embodiment, a plurality of individual light sources are used each having a different angle of reflection from the surface. By selecting the light source having an angle of reflection to match the Z dimension of the surface to be navigated the device can be used over a wide range of Z dimensions. In one embodiment, the selection of the proper light source is accomplished upon start-up of the device with respect to a particular surface and in another embodiment a user can adjust the light surface to obtain optimal performance.
