depth sensor
Proximity detection device
A depth sensor is a device that measures distance to objects or surfaces, creating data about three-dimensional space.
Common in smartphones, gaming systems, and autonomous vehicles, depth sensors enable features like facial recognition, gesture control, and obstacle detection.
They work through various technologies including infrared projection, time-of-flight measurement, or stereo cameras: The phone's depth sensor creates portrait-mode blur by mapping distance to the subject.
