Abstract: The frame rate of existing stereo cameras is not enough to track quick hand or finger actions. It also requires lots of computational cost to find correspondence between stereo images to compute distance. The recently commercialized 3D position sensors such as TOF cameras or Leap Motion needs strong illumination to ensure sufficient optical energy for the high frame rate sensing. To overcome these problems, this paper proposes to use a pair of optical-mouse-sensors as a stereo image sensor to measure 3D-velocity and use it to extrapolate 3D position measured by a low-frame-rate stereo camera. It is shown that quick hand actions are tracked under ordinary in-door lighting condition. As 2D velocities are computed inside the optical-mouse-sensors, computation and communication costs are drastically reduced.
