    • 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.
    • 公开了一种用于使其指示装置在表面上的运动的指示装置和方法。 指示装置包括照明系统,成像系统和控制器。 照明系统产生多个波长带中的光并用来自波长带中的一个的光照亮指示装置下方的表面。 成像系统记录被照射表面的图像。 控制器选择用于照亮表面的波长带,比较当用该波长带照射表面时在不同时间由成像系统记录的第一和第二图像,并且确定指示定位装置在其间移动的方向和距离的位移 两个不同的时代。
