Breakdown of the PlayStation VR communication protocols for programmers.

This Wiki is hosted on the web at This site automatically tracks the master branch.

This wiki is an attempt to collect all available and useful information for developing programs that interact with the PSVR.

As the protocol itself is not officially documented, all information collected is the result of reverse engineering.

This means that much of the terminology used will vary across sources, such as the names of commands and fields.

The goal of this project is to be the canonical reference for all things related to PSVR hacking.

The parts

The PSVR comes with two main components - the actual headset, and a small processing unit that handles most of the logic. These two parts are required - the headset cannot function without the box.

The processing unit

This device sits in-between the headset and the computer.

The processing unit has multiple IO connections

The basics

There are two connections that need to be established.

First, a USB connection must be made with the PSVR processing unit. The processing unit itself acts as a USB HID device to the host computer.

The PSVR will not display any video unless the correct initialisation commands are sent via USB.

Secondly, an HDMI connection must be established with the processing unit. Depending on the display mode, barrel distortion may need to be applied to the image in order to correct for the curvature of the lens.

A full explanation of the connection methods:

Note on projects that do not use USB

Some projects (such as the MacMorpheus video player) avoid all USB communication by having an powered-on, idle PS4 connected to the processing unit via USB. This sucks because it is a pain having a PlayStation hooked up to your system. This setup also can only be used in cinematic mode
