Time-of-flight sensor
The time-of-flight sensor (also referred to as a ToF sensor) emits an infrared laser and uses the reflected
infrared energy to measure the distance and depth of objects in front of it. The data collected by the sensor
can be used to detect human presence or recognize gestures.
Note: The infrared laser emitted by the ToF sensor is invisible to the human eye.
Screen
The screen of the built-in display is where text, graphics, and videos are displayed.
Some models offer touch-enabled screens, which allow you to interact with your PC by intuitively touching
buttons, icons, and menu items displayed on the screen. Touch-enabled screens also support multi-finger
gestures.
