Abstract
One of the embodiments of the invention provides an input-output calibration method performed by a processing unit connected to an output device and an input device. The output device and the input device correspond to an output device coordinate system and an input device coordinate system, respectively. The processing unit first derives M calibration points' coordinates in the input device coordinate system by using the input device to sense a viewer specifying the M calibration points' positions, wherein M is a positive integer. Then, the processing unit uses the M calibration points' coordinates in the output device coordinate system and coordinates in the input device coordinate system to derive the relationship between the output device coordinate system and the input device coordinate system.
