MOTION TRAIL UPDATE METHOD, HEAD-MOUNTED DISPLAY DEVICE AND COMPUTER-READABLE MEDIUM

A motion trail update method includes: receiving first pose information for a target device transmitted by a first sensor at a first frequency; selecting second pose information meeting a preset condition from a second pose information queue as target second pose information to obtain a target second pose information set; performing trail smoothing on adjacent pose information and the first pose information by using the target second pose information set to obtain a smooth pose information sequence; performing mapping on each piece of smooth pose information in the smooth pose information sequence to obtain a target pose information sequence of a virtual object, corresponding to the target device, in a virtual space; and updating a motion trail of the virtual object in the virtual space. In the embodiment, according to the first pose information and the second pose information, positioning precision and motion trail update precision are improved, and interaction experience of the head-mounted display device is optimized.
