To move beyond passive viewing, many immersive spaces now incorporate interaction technology. Viewers can influence the content in real time using body movements or gestures, transforming the experience from observation to active participation
Common Interaction Sensing Technologies
- Infrared Sensing: Detects interruptions in an infrared grid. Low cost, fast response, suitable for indoor walls or floor interaction.
- Radar Sensing: Uses millimeter-wave or radar to detect motion. Offers longer range, immunity to lighting conditions, and good performance in larger or multi-user spaces.
- Laser Sensing: Provides the highest precision (millimeter-level tracking) and supports long-distance touch-free interaction. Frequently used in premium education, museum, and high-end brand installations.
How Interaction Integrates with Content
- Curved Projection + 360° Content + Interaction Viewers can enjoy full 360-degree video without wearing VR headsets, and use gestures to interact — such as pushing aside elements, triggering changes, or exploring hidden details within the scene.
- Professional Content Creation Tools
- TouchDesigner: Industry-leading real-time visual engine, excellent for generating dynamic effects (particles, fluids, shaders) that respond instantly to body movement. Commonly used in art installations, brand activations, and high-impact interactive experiences.
- Unity: Powerful 3D engine ideal for building narrative-driven, physics-based, or character-interactive content. Frequently applied in educational simulations, training modules, or extended immersive scenarios.
