Gaze detection

           
Eye detection is an accessibility that can be done by operating the device.
It was made mainly for people with upper body disabilities.
It determines where the user is looking, moves in accordance with their gaze, and determines that they are tapping with a specific movement (such as blinking).
In Windows 10, there is a feature called "Eye control" that enables these operations by using a specific third party (i.e. a machine to be attached externally).
It is also possible to read out the input text, so that people who can only move their eyes due to illness can communicate with each other.
