Motion sensing is of fundamental importance for user interfaces and input devices. In applications where optical sensing is preferred, traditional camera-based approaches can be prohibitive due to limited resolution, low frame rates, and the required computational power for image processing. We introduce a novel set of motion-sensing configurations based on laser speckle sensing that are particularly suitable for human-computer interaction. The underlying principles allow these configurations to be fast, precise, extremely compact, and low cost.
