Eye Tracker VR Add-On – Magnetic Module with Foveated Rendering

Focus 3 eye tracker add-on: overview

This eye tracker is a magnetic add-on that brings precise eye tracking to the VIVE Focus 3, capturing blinks, eye openness and pupil position.

Two tracking cameras with built-in IR illuminators follow the eyes continuously; the data enables gaze heat maps and user-behaviour insights for training, research and marketing.

Supported apps can use foveated rendering, sharpening the image where you look while reducing peripheral detail to ease GPU load.

How to choose the right VR accessory

Check the exact headset model first. VR accessories are rarely universal: a Quest 3 strap does not fit a Quest 3S facial interface slot, a VIVE Pro link box is different from a VIVE Pro 2 link box, and base stations 1.0 and 2.0 cannot be mixed. The compatibility section above lists every headset the part is designed for.

For PC VR connections, confirm your graphics card's outputs (DisplayPort, USB-C with DisplayPort, HDMI) and your USB ports before buying cables, link boxes or wireless adapters. Longer cables add freedom of movement but need careful routing to avoid tripping.

For comfort and hygiene, shared headsets benefit from wipeable silicone or leather-style covers and spare facial interfaces, while battery straps and charging docks make long sessions and quick turnarounds easier.

Setup and use

1. Remove the face insert.
2. Attach the eye tracker magnetically.
3. Refit the face insert and connect USB-C.
4. Calibrate in the headset settings.

Care and maintenance

Keep tracking sensors and IR windows clean and free of stickers or tape, charge devices regularly, and update firmware through the companion software to keep tracking accurate.
