TTT: Time Synchronization Method by Time Distortion for VR Training including Rapidly Moving Objects

Providing an experience that includes high-speed objects, such as tennis balls, with a virtual reality (VR) training environment might provide efficient training for trainers but is challenging to achieve. Because of the drawing performance of the display, high-speed objects are perceived as poor visual information more than in reality, such as images in a stroboscope. The faster the object, the more noticeable it becomes, and the harder it is to perceive it correctly. Therefore, if the training is performed at the actual speed, the perception becomes more difficult than real space training due to the low reproduction accuracy. To solve this problem, we propose the computational time-space that controls high-speed objects in VR space, based on the user’s body movement. The method facilitates the perception of fast-moving objects by synchronizing the time of the ball with the movement of the body.
