The technologies solve different sensing problems “Infrared” and “camera” are broad categories, not single products. A fair comparison separates at least four approaches: Some depth cameras also use infrared light. Therefore, “LiDAR vs infrared vs camera” is a convenient buyer’s phrase, but the actual engineering comparison must use specific device architectures and test conditions. Side-by-side…
What is LiDAR interactive projection? LiDAR interactive projection uses a light detection and ranging sensor to measure positions in or near a projected area. Software converts those measurements into interaction events, such as a touch-like contact, an entered zone, a step, or a tracked object. The application then updates the projected image. LiDAR is the…
What is floor interactive projection? Floor interactive projection places digital content under visitors’ feet and uses sensing software to respond to steps, movement, position, or gestures. Common effects include ripples, particles, trails, virtual objects, competitive games, and information that opens when a visitor enters a zone. The attraction is immediate: people see the image in…
Why interactive projection projects are easy to mis-specify An interactive projection system is a chain: surface, light, projector, sensor, computer, software, content, installation, and operations. A strong component cannot compensate for every weak link. Buyers often compare one headline number—projector lumens, touch points, or sensor range—without checking whether the complete system works in the target…
What is wall interactive projection? Wall interactive projection combines a projected image with sensing and software so users can influence content by touching, pointing, gesturing, or moving near a wall. Depending on the design, the “wall” may be a painted surface, projection screen, scenic panel, or custom architectural feature. Unlike a conventional video wall, the…
Interactive projection applications: where does the technology create real value? Interactive projection turns a wall, floor, table, or custom surface into a responsive digital experience. A typical system combines a projector, an interaction sensor, a computer, and software. The sensor observes a touch, step, gesture, or object; the software interprets that input; and the projected…
A visitor waves their hand in the air, and a menu opens. They pinch to zoom into a product model, then swipe left to rotate it. No screen. No buttons. No physical contact. This is not a concept — it is what LiDAR-powered gesture recognition delivers today, and it is reshaping how people interact with digital content…
A demo that works flawlessly in a 3-meter meeting room can fall apart when you need to cover a 10-meter exhibition wall, a curved dome, or an L-shaped corridor. The culprit is rarely sensor quality — it’s the assumption that one sensor can see everything. Multi-LiDAR cascading solves this by assigning each unit a specific zone…
Interactive floors and walls have moved from novelty to expected feature in a short window of time. Science museums, brand experience centers, hotel lobbies, and retail flagship stores are all operating interactive installations today. The question for venue owners and operators is no longer whether to invest in interactive technology — it is how to…
The brief always sounds straightforward: make the space interactive. Walk in, reach out, and the environment responds. But the gap between that vision and what the sensor hardware can actually deliver has tripped up more than a few immersive installation projects. At CPJROBOT, we hear similar stories from experience designers and creative studios: the technology…
