OnScreen is the virtual on-screen keyboard. OnScreen with CrossScanner includes a program called CrossScanner that can interface with a "switch" Usually these switches are large button (single contact, NO-Normally Open) switches that can be tied into a keyboard, mouse, or joystick device (advanced switches can be laser based, pressure based, etc. including eye-blink contacts, muscle & other biometric based approaches (but still need to be tied to a keyboard, mouse, or joystick device). A switch closure can then be monitored by CrossScanner to create a "switch hit" - Using a LineScan (scans down the screen), and a FingerScan (scans across the screen along the line scan stopped position), CrossScanner can generate clicks, double-clicks etc., allowing an individual to operate Windows by using a single switch. If you can operate any type of pointing device at all, then you do not need CrossScanner. If all you can do is operate a single device (switch), then CrossScanner is useful.
