Abstract: A touch screen device configured to implement an auxiliary virtual keyboard on a touch screen, the device having touch/gesture sensing and image display functions, a processor, and memory storing control code and data defining the keyboard comprising a set of keys and a key layout map. The processor is configured to determine a size of a window in which the keyboard is to be displayed as a strip of keys; send instructions to display a partial view of the keyboard within the window so that a subset of keys are displayed, whereby the keyboard is scrollable in response to user input to alter the partial view to display a different subset of keys; receive touch data; map said touch data to a key using the key layout map to identify a touched key; and provide a response dependent on the identified touched key.
