Abstract
A data acquisition method and apparatus for a head-mounted display device, a host and a head-mounted display device are provided. The method includes: acquiring user head posture information collected by a head posture sensor; determining a predicted head position at a next rendering moment based on the user head posture information and a current display scene of the head-mounted display device; and acquiring a current video rendering corresponding to the current rendering moment based on the predicted head position and video data at the current rendering moment, in order that the head-mounted display device displays a rendered video at the current rendering moment and a target time warped frame, where the current video rendering includes the rendered video and one or more time warped frames for the next rendering moment, and the target time warped frame is one of the one or more time warped frames.
