A METHOD AND LASER POINTING MACHINE SYSTEM FOR INDICATING ITEMS IN A DISPLAY CASE

摘要

A method for customers to indicate items within display-cases is achieved by the control of various laser pointing mechanisms. These mechanisms comprise mechanical and sensory components that limit the spatial region within which the lasers operate. Sensors determine the location and angular orientation of the laser and confine the laser to only illuminate points within a display case. A robotic machine with an end-effector is adapted to manipulate a laser diode. It is linked to a gesture recognition component which is comprised of a capture device and a computer that processes signals from the capture device. A customer points within the field of detection of the capture device and a vector corresponding to the direction of which the pointing member is pointing is computed. The robotic machine is oriented to illuminate a point that corresponds to the intersection of the vector with a topographically analyzed surface within the display-case.
