• Develop XR applications using OpenXR covering architecture implementation testing and iteration.
• Build interactive features including:
• Input handling (controllers hands action sets haptics)
• Scene and interaction systems (grabbing ray interactions UI in 3D)
• Rendering and performance optimizations (frame pacing latency-sensitive updates)
• Integrate platform/runtime features where applicable (tracking spaces anchor-like constructs passthrough/scene understanding via extensions).
