GazeMultiGrab allows you to aim with your eyes, move with one hand and climb with two. Understand feedback, accuracy, privacy, and interaction testing.
Direct answer
Meta XR Interaction SDK Essentials 207 adds gaze interactions, GazeMultiGrab for moving, rotating, and scaling objects with one or two hands, continuous hover, and slider and scroll support. Gaze reduces movement to select targets, but should not trigger irreversible actions alone. Projects need to provide confirmation, feedback, fallback, and careful handling of eye tracking data.
Looking points; gesture confirms
Separating visual intent from manual confirmation reduces accidental activations and makes the state of the interaction more understandable.
Two hands magnify manipulation
One hand can move while the second controls rotation and scaling. Limits, snapping, and undo help maintain accuracy in business tasks.
Hover needs to be discrete and continuous
The spotlight follows the observed target, but excessive brightness or movement can be distracting. Contrast and latency must be evaluated in the headset.
Eye tracking is sensitive data
Avoid recording raw trajectories unnecessarily. Define purpose, retention, access, and alternative for devices or people without eye tracking.
Nexus Reading
Test time, error, fatigue and abandonment against raycast and control. The best modality is the one that preserves the task for more people, not the newest one.
FAQ
Does GazeMultiGrab work with one hand?
Yes. The component allows you to move with one hand and add the second to rotate and scale.
Is the feature stable?
Building Block's documentation presents it as experimental; behavior and cost may change.
Is it necessary to store gaze data?
Not for basic interaction. Telemetry must be minimized and aggregated according to the purpose and applicable rules.
