Commercial Drivers: Why Interactive Projection Boosts Restaurant ROI
Modern dining venues use interactive projection to turn passive waiting and eating time into active engagement:
- Higher Average Check & Premium Pricing: Immersive 3D environments allow restaurants to offer premium-priced tasting menus, private banquet rooms, and signature dining experiences.
- Organic Social Media Exposure (UGC): Interactive elements—such as projected flowers blooming under a plate, virtual aquatic life scattering upon touch, or interactive tabletop games—naturally encourage guests to record videos and post to Instagram, TikTok, and Xiaohongshu.
- Reduced Perception of Wait Times: Interactive tabletop games, digital menu browsing, and virtual chef demonstrations keep guests entertained during food preparation.

Technical Superiority: PoeLidar vs. Legacy Sensing in Hospitality
Unlike industrial Lidars adapted from robotics, POELIDAR was developed by Shanghai CPJRobot Co., Ltd. specifically to address spatial touch interaction in commercial hospitality.

Key Interactive Application Scenarios in Dining Spaces
1. Interactive Dining Tables & Bar Counters
- User Experience: Tables transform into dynamic digital surfaces where guests tap to browse 3D menus, view ingredient sourcing, watch virtual chef demonstrations, or play multiplayer tabletop games while waiting.
- POELIDAR Solution: Mounted discreetly overhead or at table edges, POELIDAR-M1 creates a non-contact laser sensing plane hovering 0.5cm above the table. Because there is no physical touch screen on the table surface, spilled drinks, oil, or hot plates do not affect performance or damage hardware.
2. Immersive Private Banquet Rooms & Theme Walls
- User Experience: Room walls project continuous ambient scenes—such as bamboo forests, underwater reefs, or starry night skies—that respond dynamically when guests walk past or reach out to touch the wall.
- POELIDAR Solution: A single POELIDAR-F1 sweeps a 270° plane covering up to 11+ meters of continuous wall area. Its 30 FPS refresh rate and sub-2cm accuracy map hand gestures instantly to complex high-resolution graphics without lag.

System Integration & Maintenance Advantages
CPJRobot engineered PoeLidar hardware and software to streamline deployment for venue integrators and installers:
- Single-Cable POE Deployment: Operating under the IEEE 802.3af POE standard, both power and data transmit over a single CAT6 Ethernet cable up to 100+ meters, eliminating local power outlet runs near dining tables.
- Automated Operational Maintenance: Software auxiliary tools include automatic system boot-up and shutdown synchronized with host PCs, alongside automated loop playlists for game programs.
- Universal Protocol Output: Native support for TUIO, Windows Multi-Touch, Unity, Unreal Engine, TouchDesigner, C++, C#, and Processing allows developers to quickly deploy custom interactive themes.
Conclusion
By unifying Power over Ethernet deployment, active Time-of-Flight laser accuracy, and non-contact “air-touch” operation, PoeLidar enables restaurant operators and AV integrators to build reliable, high-margin, interactive dining environments.
