摘要： An optical navigation device includes a housing, a light source, a navigation sensor, and optics. In accordance with the invention, the light source is a vertical cavity surface emitting laser (VCSEL) that is configured to generate coherent light in the visible light spectrum. For example, the VCSEL generates red coherent light in the range of 600-700 nm. In an embodiment, the VCSEL generates red coherent light at 665 nm±20 nm. Because the light generated by the VCSEL is in the visible light spectrum, a human will sense contact with the corresponding beam and will naturally react to avoid injury. This enhances the overall safety of an optical mouse. Additionally, when using a VCSEL that generates visible red light, it is easy to visually determine whether or not the beam is focused directly on a measurement sensor during calibration.

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： 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： 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： Magnetic force is used to re-center a puck in a pointing device or similar transducer-based device. A user can apply finger pressure to move the puck laterally away from the central position. The puck has a first magnet system, and the base of the device has a second magnet system. The magnetic repulsion or other magnetic interaction returns the puck to a central position when the user removes the finger pressure.
