â–¼ Sony applies for new patent to improve VR tracking technology from Baidu VR Sony is applying for a Lighthouse-style VR tracking system. Sony wrote in the patent description: A method for determining the orientation of a controller light sensor relative to a projector, which involves generating a light beam through a beam generator of a projector. . The method further includes the steps of: adjusting a direction of travel of the light beam by a microelectromechanical system (MEMS) mirror moving in a particular mode; deflecting the light beam; calculating a time when the light beam is monitored and based on the mode and The time is used to determine the orientation of the light sensor. Although this may sound confusing, it basically outlines a device similar to that used by Vive: a beam projector that uses light beams and mirrors (similar to the principle of sonar) to determine the player's play space. s position. For those who do not understand the difference between an external system (such as HTC Vive) and the PSVR built-in system, this all boils down to immersion. Currently, PSVR uses a built-in system that relies on beams from heads-up and PlayStation cameras to allow players to stay in the virtual world, but gives the player little mobility. Although there are disadvantages in the external tracking solution, the accuracy will be higher, so that the PSVR will compete with Oculus and Vive in tracking performance. Although the performance of the PlayStation 4 may not be comparable to the latest technology game computers, at least when developers develop games, they are given a similar set of tools. Regarding this patent, we have already basically understood, but whether it will be applied in PSVR second generation, we cannot guarantee, but this patent is a relatively big help to PSVR unstable tracking performance.
