A data entry device (10) having an integral input element (12) capable of recording input movement in two dimensions (including Chinese strokes and characters, Roman letters and Arabic numerals) and delivering resultant signals to a processor (11). The processor (11) is programmed for identifying a handwriting input represented by the signals. The apparatus includes an array of switching elements (20) capable of recording input movement between at least four discrete points arranged in two dimensions and providing a series of discrete input. An electronic display (13) is provided for displaying a first subset of two-dimensional information, while a memory (15) is provided for storing a larger second two-dimensional information set. The memory (15) has storage capacity for the second two-dimensional information of a size greater than the first two-dimensional information capable of being displayed on the electronic display (13). Accordingly, a processor (11) coupled with the array of switching elements (20) is provided for information processing such that the display (13) and the memory (15) are selectable by the processor program (14) for correlating the first two-dimensional information with a series of discrete inputs received from the array of switching elements (20). The display (13) of the first two-dimensional information is provided as representative of information taken from the second two-dimensional information stored in the processor memory (15).
