Abstract: An optical mouse configured to track motion on a broad range of surfaces is disclosed. In one embodiment, an optical mouse includes a light source configured to emit light having a wavelength in or near a blue region of a visible light spectrum, an image sensor positioned relative to the light source such that light from a specular portion of a distribution of light reflected by the tracking surface is detected by the image sensor, and a controller configured to receive image data from the image sensor and to identify a tracking feature in the image data.

Abstract: Various embodiments of optical mice are disclosed. One embodiment comprises a light source configured to emit light having a wavelength in or near a blue region of a visible light spectrum toward a tracking surface at an oblique angle to the tracking surface, an image sensor positioned to detect non-specular reflection of the light from the tracking surface, and one or more lenses configured to form a focused image of the tracking surface on the image sensor at the wavelength in or near the blue region of the visible light spectrum emitted by the light source. Further, the optical mouse comprises a controller configured to receive image data from the image sensor and to identify a tracking feature in the image data.

Abstract: Embodiments of diffuse optics in an optical mouse are disclosed. In one embodiment, an optical mouse comprises a light source configured to emit light toward a tracking surface, an image sensor, an optical diffuser disposed optically upstream of the tracking surface and configured to diffuse light from the light source that illuminates the tracking surface, and a controller configured to receive image data from the image sensor and to identify a tracking feature in the image data.
