If you have participated in this year's CES show, you must have found that everyone is emphasizing "inside-out positioning technology." Oculus, Qualcomm, Intel, and Microsoft have also demonstrated their own inside-out positioning technology VR head. Now, Sony is also applying for a practical patent that can bring inside-out location tracking to interactive VR devices.
This patent application was originally filed on December 6, 2016, and its patent application is summarized as follows, similar to the method used by the existing inside-out positioning technology.
Methods, systems, and computer programs for generating interactive space are provided. A method includes an operation of associating a first device with a reference point in 3D space; based on inertial information captured by the first device, and using dead reckoning to calculate a position of the first device in 3D space. In addition, the method includes an operation of capturing an image using a camera of the first device, and an operation of recognizing a position of one or more static features in the image. The position of the first device is corrected by the position based on the one or more identified static features, and a view of the interactive scene is presented in the display of the first device, wherein the interactive scene is bound to the reference point and includes Virtual object.
Sony previously had a patent similar to SteamVR positioning technology that enables a room-scale VR experience. However, the patent application does not mean that it will eventually be applied to actual products.
