Abstract:
A method for calibrating a sensed range of motion of a manipulandum of an interface device, the method comprising:providing a predetermined initial range of movement for said manipulandum when said interface device is initially powered, said initial range including two boundary values, said boundary values including a maximum value and a minimum value; receiving a sensor value representing a position of said manipulandum of said interface device in said range of movement as said manipulandum is moved; setting said maximum value or said minimum value to said received sensor value if said received sensor value is outside said initial range; and adjusting said other of said boundary values not set in setting said maximum value or said minimum value to maintain said initial range between said maximum value and said minimum value unless said other of said boundary values has been previously detected to be outside said initial range.
