How to control OnScreenKeys
OnScreenKeys comes into action when the normal computer keyboard cannot be used.The following input devices can be used:
- Touch-sensitive screens
E. g. Touchscreen/Tablet-PC - Mouse
If the user can still move the computer mouse but cannot press down the mouse buttons, OnScreenKeys' auto-click (Dwell click) will automatically click the mouse button or key on the keyboard after a freely definable time period. - Eye tracker
A camera notices where the eyes of the user is looking at. Blinks of the eye or simply staring at one position for some time causes a click or the pressing of a button. - Head mouse
A camera notices in which direction the user moves his head. OnScreenKeys triggers a click or a key press at the wanted position after a certain dwell time. - Mouth mouse By the use of a mouth mouse, the mouse pointer can moved to the wanted position on the screen. The click is done automatically by OnScreenKeys.
- Simple switch/ button (with Mouse Scanning) In mouse scanning mode, a line moves from the top to the screen to the bottom of the screen. By triggering a click, the desired row is being highlighted. Afterwards, the desired vertical position ("Column") is selected by the same procedure.
