Abstract
A calibration system configured to calibrate a handheld controller is disclosed. The calibration system includes a tracking camera, a displayer and a processing unit. The tracking camera is configured to capture streaming images involving the handheld controller. The displayer is configured to display a calibration test instruction. The processing unit is configured to receive first movement data generated by the handheld controller while the handheld controller moving; receive the streaming images captured by the tracking camera generated while the handheld controller moving; calculate second movement data according to the streaming images; calculate calibration parameters by comparing the first movement data and the second movement data; and, transmit the calibration parameters to the handheld controller. The calibration parameters are utilized by the handheld controller in generating a third movement data.
