Abstract
A technique for controlling operation of a device with a virtual touchscreen includes defining an area of a surface, associated with the device, as the virtual touchscreen. An operation within the device is then initiated based on activity within the virtual touchscreen. An overlay may be provided, on a display screen of the device, to indicate a location of the virtual touchscreen with respect to, for example, a keyboard of the device.
