Abstract
Compact opto-electronic sensor modules are described that allow detection of an object's motion occurring in spatial regions (e.g., quadrants) that are located primarily directly about the surface of a device in which the module is located. For example, light (e.g., infra-red) from a light emitting element in the module can illuminate substantially all, or at least a significant percentage of, areas in a plane directly above the surface of the device. Each of multiple light detecting elements in the module can be arranged to receive light from a respective detection zone directly above the surface of the device.
