Meta Quest 3 Development Guide

Design XR interactions that feel natural on the Meta Quest 3 by focusing on comfort, clarity, and responsiveness.

Interaction Principles

• Hands-first: Prioritize hand tracking and pinch gestures; controllers are secondary.
• Clear affordances: Use sizing, color, and subtle animation to show what can be grabbed or pushed.
• Short sessions: Keep each flow under 15 minutes to avoid fatigue.

Input Patterns

Scenario	Recommendation
Selection	Use ray pointer with confirmation haptics as fallback for hand tracking.
Manipulation	Rely on two-handed scaling gizmos with position constraints.
System actions	Implement palm-up menu; include voice shortcuts for expert users.

Performance Targets

• 90 FPS sustained with ASW disabled.
• GPU frame time under 8 ms and CPU frame time under 10 ms.
• Memory footprint under 2.5 GB.

Testing Checklist

• Verify guardian boundary prompts appear correctly.
• Validate mixed reality capture composition with standard lighting.
• Test both color passthrough and fully immersive modes.

Document usability findings in the shared IRIS testing template after each playtest.
