VR Half Moon Talk No. 29: HTC Releases New VR Head Display, Ministry of Industry and Information Technology Issues Document to Promote VR Industry Application

From the information revealed so far, it is speculated that Vive Cosmos should use the Inside-Out tracking principle, which can be confirmed by the features of the four cameras on the front and side of the distribution head, and the aperture on the handle. The Inside-Out tracking mechanism is widely used in high-end all-in-ones including HTC’s own Vive Focus and Microsoft’s MR head display. It is quite good in terms of actual use effect, and a large number of experiencers can maintain 80% of the positioning ability.  __

Currently, top VR head-ends such as HTC Vive and Oculus Rift have independent external positioning systems. For example, Vive uses Valve’s Lighthouse technology to continuously scan the user’s actual space, head and handle with a pair of independent laser base stations. The receiver can determine the position and displacement by the phase change of the laser signal to achieve precise positioning. Inside-Out uses the camera on the head to scan the environment, establishes the corresponding model and performs its own positioning. For the somatosensory handle, it often needs to be illuminated by its own light.__

Camera recognition. However, since the camera on the head is often unable to cover the user’s 360-degree environment, the typical Microsoft HP’s MR head has two cameras on the front. This configuration is easy to bring up when the handle needs to be displaced.__

When the arrow is ready to pull the bow, the handle is temporarily out of the tracking range of the camera, and can only rely on its own inertial positioning, which is prone to jitter or loss and cause the user to play. In addition to the two cameras on the front side, Vive Cosmos also has cameras on both sides, totaling four, which can alleviate the embarrassing situation of the handle tracking to a certain extent, and of course contribute to its own positioning.
