HTC Vive XR Elite 'Full Face Tracker' Addon With Eye Tracking Is Out Now
The HTC Vive XR Elite 'Full Face Tracker' addon is now available for purchase at $200. It attaches magnetically under the facial interface of the Vive XR Elite headset and connects to the secondary USB-C port. The addon features two 120Hz eye tracking cameras and one 60Hz lower face tracking camera. HTC claims that it accurately portrays facial expressions and matches them with spoken words in real-time. The eye tracking cameras are also used for foveated rendering and measuring IPD for automatic lens separation adjustment. A software update to support the addon will be released tomorrow for Vive XR Elite, and developers can access the face and eye tracking data using either the Vive Wave SDK or OpenXR. The addon is not available for Meta's Quest 3 headset. Users can read the full story on UploadVR.
