As I eluded to in my post about Mac Accessibility For Severely Motor Impaired Users the release of macOS High Sierra has seen the inclusion of an onscreen keyboard increasing the accessibility of all Macs from day one of purchase. This is a feature that has been available on the Windows platform for several years but it’s eventual inclusion in macOS is a welcome addition for motor impaired Mac users. Below is a walk through about displaying the new onscreen keyboard.
First, select the System Preferences icon, I keep mine in the dock for easy access (img.1).
When the System Preferences window displays you will see an Accessibility icon in the lower region of the window, click on this (img.2).
In the Accessibility window that is displayed scroll down in the left area of the window to Keyboard and then select this (img.3).
Select the Accessibility Keyboard tab at the top of the Keyboard window (img.4).
Now just check the Enable Accessibility Keyboard checkbox and the onscreen keyboard will be displayed (img.5), the user can drag the onscreen keyboard to their desired position.
The keyboard is displayed until the above is reversed or the ‘x’ is sliced in the top left of the onscreen keyboard.
