Update for Unreal adds gauze and controller-driven hands. See how to align representation, collision, feedback, and testing across modalities.
Direct answer
The Meta XR Interaction SDK for Unreal 207 adds gaze interactions on eye-tracking devices and enables controller-driven procedural hands in the Native OpenXR way. The representation can preserve the presence of hands when the user uses controls, but it needs to match the real action, avoid impossible poses, and provide consistent feedback when switching between control, hand, and gaze.
Virtual hand needs to explain control
Pose, scope, and animation should communicate what the button or axis performs. A beautiful but misaligned hand reduces confidence and precision.
Gaze reduces movement, but asks for confirmation
Gaze can quickly select a target; Critical actions should require explicit gesture, button, or step to avoid unintended activations.
Modality switching is a state of the product
When switching between controls, hands and gaze, preserve focus, grasped object and instruction. Silent transitions generate errors that are difficult to reproduce.
Procedural does not mean universal
Hand size, laterality, accessibility and amplitude vary. Collision, occlusion, two-handed testing, loss of tracking and recapture.
Nexus Reading
Define an interaction contract per task and validate time, error and fatigue in each modality. Use procedural representation for operational clarity, not just decoration.
FAQ
Do procedural hands require hand tracking?
Not necessarily; the note describes hands directed by the controls in the Native OpenXR path.
Does gauze work on any headset?
Depends on device with eye tracking and integration and runtime support.
Is it necessary to maintain fallback for control?
Yes. Capacity, preference and accessibility vary between devices and users.
