## Long description

The HTC VIVE Focus 3 Eye Tracker is an add-on eye-tracking module designed for the VIVE Focus 3 head-mounted display. It connects via USB‑C and adds gaze-tracking capabilities to virtual reality sessions. The compact black accessory weighs 54 g and ships as a single unit with the required cable. The module attaches magnetically to the headset, supports IPD adjustment and provides data suitable for foveated rendering, user research, accessibility features and interactive VR applications.
Advantages
The eye tracker enables precise measurement of gaze origin, gaze direction, pupil size, pupil position and eye openness through a dual-camera arrangement with IR illumination. It supports dynamic foveated rendering to reduce GPU workload by prioritising rendering where the user is looking. The magnetic, low-profile design preserves headset ergonomics while remaining easy to attach and remove. Integration of eye-based input allows hands-free navigation and interaction, which can simplify controls and improve accessibility for users with limited mobility.
Suitable for
User research and behaviour analysis, including heat maps and gaze analytics
Developers implementing foveated rendering and GPU optimisation
Accessibility solutions and hands-free interaction methods
Virtual collaboration, avatar animation and realistic non-verbal expression in VR meetings
Performance capture and facial animation for games, AR and VR content

How to use
Attach the eye tracker magnetically to the front of the VIVE Focus 3 headset and connect the USB‑C cable to the compatible port. Use the headset software to complete any required calibration and IPD adjustment guided by the eye-tracking feedback. After calibration, launch compatible VR applications or development tools that accept eye-tracking input to enable gaze-driven features such as foveated rendering, gaze-based menus, avatar eye animation and analytics capture.
Usage recommendations
For reliable tracking results, perform a calibration step each session and ensure the IR illuminators are not obstructed. Keep the lens area and tracker cameras clean and avoid high-glare lighting directly facing the sensors. Use compatible applications and follow developer guidance when implementing gaze-driven rendering or user analytics to make best use of the data provided by the eye tracker.
