Quest Pro and Mixed Reality: New Requirements for VPS

How Quest Pro's mixed reality capabilities change the requirements for visual positioning - higher accuracy, lower latency, always-on.

Quest Pro brings full-color passthrough and mixed reality. VPS needs to level up to match.

Quest Pro Capabilities

  • High-resolution color passthrough cameras
  • Better tracking (more cameras, faster IMU)
  • Improved processors (more compute available)
  • Eye tracking and face tracking

MR mode: Digital content mixed with real world.

VPS Requirements Shift

Higher Accuracy Needed

VR: Virtual content in virtual world. Small errors invisible. MR: Digital content on real surfaces. Errors are jarring.

VR target: 10cm accuracy acceptable MR target: 2cm accuracy needed for believable placement

Lower Latency Needed

VR: Content locked to headset. Latency to world doesn't matter. MR: Content locked to real world. Latency causes visible drift.

VR target: 500ms initial localization fine MR target: under 200ms initial, continuous refinement

Always-On Requirements

VR: Localize once at session start. MR: Continuous localization as user moves through space.

Power budget implications: Can't be a power hog if always running.

Technical Adaptations

Continuous Localization

VPS becomes part of the tracking pipeline:

VIO tracks frame-to-frame
VPS corrects drift periodically
Combined: Accurate + responsive

VPS queries every few seconds, not just at startup.

Tighter Integration

VPS and VIO share information:

  • VIO provides motion prior to VPS
  • VPS provides absolute correction to VIO
  • Kalman filter combines both

Previously separate systems, now fused.

Quality of Service

MR needs predictable performance:

  • Bounded latency (no 5-second queries)
  • Graceful degradation (don't freeze on failure)
  • Confidence indication (know when uncertain)

Development Timeline

Quest Pro ships October 2022. VPS MR support target: Launch readiness for Quest Pro.

We have 6 months. It's aggressive but achievable.

Key milestones:

  • Q1: Architecture for continuous localization
  • Q2: Integration with VIO team
  • Q3: Performance optimization
  • Q4: Polish and launch

The Opportunity

Quest Pro positions VPS as core infrastructure:

  • Every MR experience potentially uses VPS
  • Pre-installed on millions of devices
  • Foundation for spatial computing future

Higher stakes, higher visibility, higher impact.
