Spatial Computing

Spatial computing is a collection of technologies that let digital information exist and interact within three-dimensional physical space. It blends sensors, computer vision, graphics, and real-time processing to map the geometry of an environment and overlay data onto that map.

Apple Vision Pro is the most prominent recent example, blending virtual interfaces with the user's physical surroundings. In retail, smartphones scan store aisles to show product reviews and stock levels. In construction, depth-sensor helmets project wiring diagrams onto walls. In education, any surface can become an interactive display for 3D molecular models or historical artifacts.

The technology stack includes SLAM (Simultaneous Localization and Mapping) for environment understanding, LiDAR for depth sensing, and GPU-accelerated rendering for real-time graphics. As these components get cheaper and smaller, spatial computing will move from specialized headsets into everyday glasses and eventually contact lenses.
