Update adds selection by gaze, fallback by head and tests in the editor. Understand the gains and limits for VR interfaces.
Direct answer
On September 22, 2026, Meta updated the XR Interaction SDK for Unreal 207 with gaze interactions combined with pinch, head direction fallback, priority for nearby hands and mouse gauze testing in the editor. The features accelerate prototyping of VR interfaces, but must be validated in the headset for target, jitter, fatigue, gaze privacy, and accessibility. A technically recognized interaction does not guarantee clear intent or comfort.
Gauze reduces pointing effort
Looking can anticipate the target and the clamp confirms the action, reducing range of movement.
Fallback expands coverage
Head steering offers an alternative when eye tracking is not available, with different precision and ergonomics.
Priority avoids disputes
Giving precedence to the nearby hand helps when ray, touch, and gauze compete for the same object.
Editor accelerates, headset validates
Mouse reproduces logic, but does not represent eye noise, display adjustment, or stereo perception.
Nexus Reading
Set tolerant targets, explicit confirmation and input alternatives, then test with different profiles.
FAQ
Does version 207 require eye tracking?
Not necessarily; Meta reports fallback by head direction.
Is it possible to test without a headset?
The editor offers mouse-controlled gauze to iterate logic.
Should Gaze activate actions alone?
For sensitive actions, additional confirmation reduces unintended activations.
