LiDAR-based interactive technology—often referred to as “LiDAR sensing interaction”—is an advanced human–computer interaction solution that uses LiDAR sensors (Light Detection and Ranging) to detect human position, movement, and gestures in real time. These spatial data are then converted into interactive responses such as visual effects, sound feedback, or lighting changes, creating immersive, touch-free experiences.
This technology is widely used in interactive projection systems, digital exhibitions, smart retail spaces, museums, and entertainment venues, where traditional touch screens are limited by size, durability, or environmental conditions.
How LiDAR Interactive Systems Work (Technical Principle)
From a professional engineering and system-integration perspective, LiDAR interaction follows a clear workflow:
1. Spatial Scanning
LiDAR sensors emit laser pulses and continuously scan a predefined area, accurately capturing distance, depth, and positional data of objects—most commonly the human body.
2. Data Processing & Coordinate Mapping
The reflected laser signals are processed by algorithms and converted into precise 2D or 3D coordinates, enabling real-time tracking of footsteps, hand gestures, and body movements.
3. Real-Time Interaction Feedback
These coordinates are bound to interactive content—such as games, animations, lighting logic, or sound triggers—so that where you walk, touch, or wave, the system responds instantly.
4. Multi-Platform Output
LiDAR interaction can be applied to:
- Wall projection systems
- Floor projection systems
- LED displays
- Interactive shop windows and digital signage
Key Advantages of LiDAR Interaction Technology
1. Touch-Free & Multi-User Interaction
LiDAR interactive systems require no physical contact. Multiple users can interact simultaneously, making them ideal for public spaces, exhibitions, and high-traffic environments.
2. Large-Area Coverage
A single LiDAR sensor can cover several meters to over ten meters, supporting large-scale installations such as:
- Immersive halls
- Large LED walls
- Interactive floor projections
3. Strong Resistance to Ambient Light
Unlike camera-based or infrared systems, LiDAR interaction is highly resistant to ambient and strong lighting conditions, ensuring stable performance in bright indoor environments.
4. Hidden Installation & Clean Design
With compact hardware that can be mounted on ceilings or corners, LiDAR sensors remain virtually invisible, delivering a clean, futuristic interaction experience.
