Abstract

The invention provides an input-output calibration method performed by a processing unit connected to an output device and an input device. The output and the input device correspond to an output and an input device coordinate systems, respectively. The processing unit uses the input device to derive a plurality of lines in the input device coordinate system for M calibration points by sensing a viewer specifying the M calibration points' positions, the plurality of lines are between the M calibration points and the viewer's the predetermined object's different positions, M is a positive integer equal to or larger than three. The processing unit derives the M calibration points' coordinates in the input device coordinate system according to the plurality of lines and uses the M calibration points' coordinates in the output and the input device coordinate systems to derive the relationship between the output and the input device coordinate systems.
