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 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 method and apparatus for focusing an image of a work surface on an optical sensor array in an optical pointing device. Light from a region of the work surface is captured by an imaging system incorporating an optical coupling system and the optical sensor array. The focus of the imaging system is adjusted in accordance with the distance between the optical pointing device and the work surface. The distance may be sensed, or inferred by adjusting the imaging system to maximize the focus of the image.

摘要： A system for optical navigation includes an optical navigation sensor integrated circuit (IC) configured to generate image information for use in navigation sensing and a collapsible structure which sets the distance between the optical navigation sensor IC and a navigation surface and which can be expanded or collapsed as needed. The collapsible structure includes a collapse system configured to allow the collapsible structure to be in an expanded state or a collapsed state. The collapse structure has a smaller profile dimension in the collapsed state than in the expanded state. The collapsible structure is placed in the expanded state for navigation sensing and in the collapsed state for storage and/or charging.
