A mobile phone app asks the user to point the phone's camera at a room and then applies the phone's LIDAR scanning function.

What does this technology do$?$

measures distances between objects to create a virtual representation of the room

scans the room to locate and connect to other Extended Reality enabled devices

records a video of the room and automatically adjusts the brightness and color balance

optimizes the frame rate of the phone's display based on the strength of the network
