Depth sensing

Definition

Depth sensing is the technology that allows devices to perceive the distance between the sensor and objects in their environment. This ability is crucial for understanding spatial relationships and creating a realistic interaction with augmented and virtual environments. It plays a significant role in accurately mapping surroundings, enabling features like object placement, occlusion, and interaction within 3D spaces.
