Vive Pro Eye

Overview​

The Vive Pro Eye provides eye gaze tracking as well as detailed eye expression tracking. It is a built-in eye-tracking device (no additional hardware setup required). Eye tracking data is accessed through Vive's SRanipal interface.

Setup​

  1. Follow the Vive hardware setup instructions that came the headset. Make sure that the headset cable is not damaged, and ideally, plug in the USB connection from the linkbox to a USB 3.0 port (usually blue internal connector tab)
  2. Install the SRanipal Runtime Software
  3. Calibrate the eye tracking with the SRanipal Vive Pro Eye Calibration tool in SteamVR

Module​

Install the "SRanipalTrackingModule" from the VRCFaceTracking Module Registry](/docs/vrcft-software/vrcft#module-registry).

Common Issues​

  • A regular Vive Pro is occasionally mistaken to be a Vive Pro Eye. A Vive Pro Eye will have light blue rings around the front two passthrough cameras and a plastic covered IR LED ring surrounding each lens on the inside
Front View
Inside View
  • The headset cable can be damaged with heavy use, especially if it gets tangled around or used with a ceiling pulley system. A damaged cable may not show tell-tale “display snow” or even obvious physical indicators, but can affect USB connectivity of the Eye but more commonly, the Vive Facial Tracker connected to the accessory port of the Eye. Replacing the headset cable will often resolve “cutting out” or “fail to initialize” face and eye tracking problems.
