Abstract:
1. A method of controlling an encrypting touch-sensitive display, the method comprising: creating a pad zone on a screen to be rendered on the touch-sensitive display; creating touch areas within the pad zone, each touch area having a value; assigning an operating mode to the touch areas within the pad zone, where the operating mode is either: (i) secure, for which the value associated with each touch area is not returned to an application on selection of that touch area; or (ii) open, for which the value associated with each touch area is returned to an application through a touch area input queue on selection of that touch area; providing an option to create a mouse area outside the pad zone on the screen to be rendered on the touch-sensitive display, but only where the operating mode of the touch areas within the pad zone is the open mode; and enabling a touch selection within the mouse area to be transferred to an operating system input queue instead of the touch area input queue.
