PROBLEM TO BE SOLVED: To calibrate a display system for detecting a position where a user touches, more properly.SOLUTION: A calibration method includes: processing S405 of causing a display device to display a figure indicating a touch route; processing S407 of causing a detection device to repeatedly detect a touch position on a surface where the figure is displayed; processing S409 of extracting a consecutive touch trajectory, on the basis of the detected touch position; processing S411 of selecting a trajectory corresponding to or approximate to the figure when a plurality of trajectories are extracted; processing S413 of generating data for associating a position of a feature point in the figure with a position of a feature point in the selected trajectory; and calculation processing S415 which calculates a parameter to be used for coordinate conversion between a coordinate system displayed by the display device and a coordinate system detected by the detection device, on the basis of the data.SELECTED DRAWING: Figure 4 |
