ABSTRACT:
An optical navigation device for operation in a surface navigation mode and a free space navigation mode is described. One embodiment of the optical navigation device includes a microcontroller, a surface navigation sensor, and a free space navigation sensor. The surface and free space navigation sensors are coupled to the microcontroller. The microcontroller is configured to process a movement of the optical navigation device. The surface navigation sensor is configured to generate a surface navigation signal in response to a surface navigation image. The free space navigation sensor is configured to generate a free space navigation signal in response to a free space navigation image. Embodiments of the optical navigation device facilitate an integrated optical solution to provide desktop navigation and scene navigation in a single optical navigation device.
