Abstract

The invention discloses a method for controlling the viewing angle of an HMD and a head-mounted display device, including: identifying the motion state of the head-mounted display device in the direction of the heading angle; if the head-mounted display device is in a predetermined state in the direction of the heading angle, the The current magnetometer data reported by the magnetometer sensor of the head-mounted display device is corrected to obtain the corrected current magnetometer data; according to the corrected current magnetometer data, the viewing angle of the head-mounted display device is controlled. The above solution is used to solve the technical problem in the prior art that the data reported by the magnetometer sensor of the head-mounted display device jitters, causing the HMD to appear jittery, so as to accurately control the viewing angle of the head-mounted display device and improve the viewing effect.

Description

Technical field[0001]The present invention relates to the field of data processing, and more particularly to a method of controlling an HMD angle of view and a header display device.Background technique[0002]In the virtual world provided by the header display device HMD (English full name: Head mount display), the head wear display device determines the physical information provided to the user by detecting the user's head gesture, and the user's head attitude is usually passed. The header display device in the IMU (Inertial MeasurementUnit; Inertial Measurement Unit) sensor is captured.[0003]The IMU sensor includes a gyroscope, an accelerometer, a magnetometer, and the like, and the existing solution is a posture estimate by fusion gyroscope, accelerometer, and magnetometer measurement data. Specifically, such asfigure 1 As shown, the HMD device defines three angles (ROLL, YAW, PITCH) to determine the gesture of the headset display device, where the roll is the horizontal roller an...
