  • Patent number: 9798381
    Abstract: The present invention describes a hands-free system for controlling the movement of a cursor on one or more display devices. A tracking device including a traceable marker and one or more accelerometers and gyroscopes are used to track position and acceleration of the marker relative to a target of interest. A processing means processes the motion signals from the tracking device to determine the location of the cursor on the operator's monitor, which may also be displayed on more monitors. The tracking device is worn by the operator, optimally on the operator's head. The operator's head movements determine movement of the cursor.
