HEAD-MOUNTED DISPLAY APPARATUS AND AUTOMATIC CALIBRATION METHOD OF TOUCH DEVICE THEREOF

Document Type and Number:

WIPO Patent Application WO/2019/100299

Kind Code:

A1

Abstract:

A head-mounted display apparatus (100) and an automatic calibration method of a touch device (54) thereof, said method comprising: predetermining an original coordinate system of the touch device (54), and a coordinate conversion formula between the actual coordinate values and the calibration coordinate values of an effective touch point of the touch device; when a relative rotation occurs between the display device (51) and the head- mounted device (53) of the head-mounted display apparatus (100), acquiring an actual angle value between a plane where the display device (51) is located and a plane where the head-mounted device (53) is located; when the actual angle value is not equal to a preset angle value and a touch operation is detected, acquiring actual coordinate data of a touch point corresponding to the touch operation in the original coordinate system; calculating, according to the coordinate conversion formula and the actual coordinate data, calibration coordinate data of the touch point in the original coordinate system; and generating a touch instruction according to the calibration coordinate data, so as to trigger a corresponding touch operation, thereby avoiding the case that the actual operation is inconsistent with the touch operation expected by the user.
