Introduction
As demand for large-scale, non-contact interaction continues to grow, single LiDAR units often fall short in range and responsiveness. That’s where multi-LiDAR cascading comes in. By integrating multiple LiDAR devices into a unified system, developers can unlock broader coverage, finer precision, and a more immersive experience—perfect for large projection walls, spliced LCD displays, exhibitions, and public spaces.
In this article, we break down the key benefits of multi-LiDAR cascading in interactive projection systems and explain why it’s becoming a standard in advanced gesture-based environments.
1. Expanded Interactive Coverage
Cascading multiple LiDAR sensors significantly extends the active detection area, making it ideal for:
- Oversized interactive walls
- Seamless tiled displays (LCD/LED)
- Exhibition booths or museum zones
- Outdoor interactive installations
The system ensures consistent sensing across a large surface without dead zones, enabling a truly immersive, borderless user experience.
2. Improved Multi-Point Precision and Stability
Multiple LiDAR units working together achieve:
- Sub-centimeter gesture tracking accuracy
- Enhanced point stability with anti-jitter algorithms
- Smooth operation in complex environments or under high user loads
This is especially valuable in multi-user scenarios where multiple fingers or hands must be tracked simultaneously without interference or lag.
3. Superior Resistance to Environmental Interference
LiDAR technology already offers strong resistance to ambient light, making it more reliable than camera- or IR-based systems in:
- Bright indoor settings
- Full sunlight
- Darkened environments
With multi-LiDAR cascading, the system can dynamically compensate for signal obstruction or blind spots, maintaining reliable tracking even in partially blocked or cluttered spaces.
4. True Multi-User, Multi-Touch Interaction
A cascading system supports simultaneous detection of 256 or more touch points, allowing:
- Multiple users to interact at the same time
- Rich, collaborative, and playful experiences
- Complex gesture combinations (e.g., pinch, zoom, swipe)
Perfect for interactive education, group games, retail, or public engagement.
5. Scalable Architecture and Long-Distance Installation
LiDAR devices are compact and support Ethernet (LAN/POE) for:
- Long-distance deployment (up to 100 meters from the host PC)
- Easy concealment of control hardware
- Flexible placement in large or modular spaces
Adding new LiDAR units is simple—just connect, calibrate, and extend. This makes the system highly modular and future-proof.
6. Software Compatibility and Protocol Flexibility
Multi-LiDAR systems are compatible with popular gesture and interaction protocols, such as:
- TUIO
- Windows Touch
- Simulated Mouse Events
They can be easily integrated into engines like Unity3D, Unreal, Processing, or Flash, speeding up development cycles for interactive games, educational tools, or artistic installations.
