Spatial Intelligence

Spatial Intelligence is AI's ability to understand, reason about, and interact with the three-dimensional physical world. This emerging field combines computer vision, robotics, and physics simulation to enable AI systems to perceive depth, spatial relationships, and physical properties—moving beyond 2D understanding to true 3D world comprehension.

🎯 Overview

What is Spatial Intelligence?

  • Perceive and reason about 3D space
  • Understand physical relationships between objects
  • Navigate and manipulate the real world
  • Build persistent spatial maps
  • Simulate physics and predict outcomes

This technology powers autonomous vehicles, robotics, AR/VR, and the next generation of AI agents that interact with physical environments.

Embodied AI

AI agents that learn through physical interaction with the environment, building spatial understanding through experience (like humans do).
