Apple released the first macOS Catalina 10.15.4 beta last night, which, in addition to introducing the usual performance enhancements and system bug fixes, also brought some interesting news.
Control the cursor with your head
In this new macOS Catalina beta, Apple has introduced an accessibility feature that allows you to control the screen cursor using head movements. This feature takes advantage of the Mac camera, activate it in the accessibility settings. The primary objective is of course to help people with motor problems.
The user can also customize it, for example by ensuring that the pointer always follows the movements of the head, regardless of the location of the forehead. By default, the system receives input from the built-in camera on the Mac, but you can also choose another device by clicking the menu next to the camera.

In addition, the function can be activated or deactivated manually, or you can create your own sequence of keys to activate or deactivate it at any time.
This is the same feature already available on iOS 13.3 and iPadOS 13.3, which is now available on macOS Catalina 10.15.4.
With this feature, parents can easily limit the people with whom their children can communicate during certain periods or at any time. These limitations do not apply to known emergency numbers.
