(Engineering & Operational Framework for Large-Space XR Venues)

1. Why Safety Systems Are Critical in XR Venues

Large-space XR environments—8×12m, 10×15m, 16×20m—allow players to move freely inside an arena while wearing headsets.
Without robust boundary systems and collision avoidance layers, operators risk:

• Player-to-player collisions

• Player-to-wall impact

• Motion confusion due to drifting

• Reduced throughput due to safety downtime

Modern XR solutions such as LEKE’s Glory Battlefield (Quest2 free-roam) rely on multi-layer digital safety frameworks.

2. Safety Zone Architecture (Three-Layer System)

2.1 Layer 1 — Physical Boundary Mapping

Before content runs, staff map the full playable area:

• Wall positions

• Obstacles

• Doors & entry points

• Equipment racks

• Minimum safe distance per player

This creates a static physical map stored in the XR server.

2.2 Layer 2 — Dynamic Guardian Boundary

Inside the headset, a real-time Guardian system projects boundaries when players approach limits.

Functions include:

• Grid overlay when within 50–80 cm of walls

• Fade-in boundary indicators

• Floor-level warning markers

• Haptic vibration on controllers

This prevents accidental collision with physical elements.

2.3 Layer 3 — Player-to-Player Collision Avoidance

A safety algorithm calculates:

• Each player’s position (6DoF)

• Movement direction

• Speed vector

• Predicted intersection within 0.3–0.7 seconds

If two players approach too closely:

• Outlines of others become visible

• Audio cue triggers

• Controllers vibrate

• System can temporarily enforce “slow zone”

This system is essential for high-traffic multiplayer venues.

3. How Collision Avoidance Algorithms Work

3.1 Real-Time Positional Tracking

Every headset broadcasts pose data at 30–90 Hz.
The XR server predicts:

Future position = CurrentPosition + (Velocity × Time)

When predicted vectors intersect, a soft-stop or warning is triggered.

3.2 Occlusion Handling

Since players can block headset cameras during fast motion, systems utilize:

• Redundant IMU prediction

• Server-based position correction

• Proximity-based safe override

This maintains tracking stability even when visual references are temporarily lost.

3.3 Arena Net-Zone Segmentation

Larger XR arenas (16×20m) divide the map into zones:

• Combat zone

• Interaction zone

• Safe idle zone

Players entering unsafe zones trigger automatic guardians.

4. Operational Safety Processes for XR Venues

High-quality XR attractions (such as LEKE’s XR arenas) include hardware-level emergency stop systems, mirroring mechanisms already present in devices like VR Cinema & Flight Chairs.

5. Commercial Impact

A well-designed safety & collision avoidance system yields:

• Higher daily throughput

• Lower operator risk

• Reduced headset damage

• Better customer satisfaction

• Easier mall approval for installation

For commercial XR operators, safety engineering is directly tied to ROI and venue scalability.
