The detection and simulation of contact events between virtual objects and real-world physical elements in mixed and augmented reality environments. Virtual-physical collision systems generate haptic alerts, visual boundary warnings, and passthrough camera activations to prevent user injury and to produce physically plausible interactions between digital content and the real world.

Overview
- Virtual physical collision systems detect and manage interactions between digital content and real-world objects. In VR, guardian/chaperone systems warn users of physical boundaries. In AR, collision detection enables virtual objects to interact realistically with real surfaces. Haptic feedback enhances immersion by simulating touch sensations.
