Motion-to-Photon Latency
<5 ms End-to-End XR Rendering Latency Guarantee
The architectural guarantee that the time elapsed between a human moving their head and the display updating with matching perspective never exceeds 5 milliseconds.
Technical Explanation
If the delay between when a user rotates their head and when the virtual perspective updates (Motion-to-Photon latency) exceeds 15-20 milliseconds, the human vestibular system detects the mismatch, causing severe nausea, dizziness, and cyber-sickness. 6G guarantees an end-to-end Motion-to-Photon latency of less than 5 milliseconds across sensor capture, 6G-Uu transmission, edge GPU rendering, and display scan-out.
Key Functions
- Guaranteeing end-to-end motion-to-photon latency below 5 milliseconds across all layers
- Completely eliminating vestibular conflict, dizziness, and VR-induced motion sickness
- Ultra-fast IMU sensor polling and predictive head orientation Kalman filtering
- Zero-wait radio scheduling using dedicated HRLLC transmission slots
- Direct display scan-out hardware pipelines synchronizing with 6G packet arrivals
