It is reported that the project using PlayStation VR2 as a PC SteamVR head-mounted device has successfully realized the position tracking function of the head-mounted display.
PSVR 2 is technically already available on PC without any third-party tools or drivers, but only in "theater mode" that shows your monitor floating in front of you, and only with specific NVIDIA 20-series GPUs. On PC, the mode also lacks location tracking.
All along, iVRy, the developer of the third-party SteamVR driver for the original PlayStation VR, has been experimenting with PSVR 2 since gaining access to it in late February of this year. Two weeks ago, iVRy enabled SteamVR output to the headset, but with one important constraint: they used a Linux PC and custom software as a "middleman" between the PSVR 2 and the PC.
At the time, another important limitation we noticed was the lack of tracking, neither position nor rotation. However, iVRy said today that they have figured out how to read the PSVR 2's 6DoF positional tracking data and pass it to SteamVR. iVRy told us they verified by walking around in SteamVR wearing a PSVR 2.
iVRy calls it possible because the PSVR 2 can do positional tracking in the headset, like a standalone headset, and send its location coordinates to the PlayStation 5 — or in this case, the PC.
However, iVRy currently only reads 60Hz optical computer vision tracking data and cannot read 2000Hz accelerometer and gyroscope (IMU) data. All VR tracking systems actually use IMU data as the primary input to minimize latency and maximize accuracy, optical tracking data is technically only used for drift correction.
The project has not yet implemented tracking for the Sense controllers, but iVRy says controller ring IR LED pattern tracking is also done on the PSVR 2 headset, so they have "no reason to think" they won't be able to get it to work eventually.
However, iVRy is currently primarily focused on replacing the Linux PC middleware -- which essentially tricks the PSVR 2 headset into connecting to the PS5 to enter VR mode -- using Raspberry Pi microcontrollers (PICOs).PICOs)。
This will serve as a reference design for providing end users with an adapter to connect the PSVR 2 to their PC via DisplayPort. iVRy stated that while they are designing this adapter, they have no intention of manufacturing it. Another company will need to actually manufacture and sell it.
So, the PlayStation VR2 can now function as a PC SteamVR headset, and it even has positional tracking, but it still requires a specific custom hardware and software setup. A finished adapter for end users is still a long way off, and no company has announced an intention to produce one yet.
