<p>The present invention describes a data input apparatus and a data input method that implement a large number of key values with a small number of switches to improve a text input and implement an efficient text input with small volume. The data input apparatus of the present invention is configured of press switches including touch sensors on a plate and forms a unit cell configured of neighboring switches, each cell and neighboring unit cells shares the switches. The data input step selects the unit cell by a simultaneous touch of two touch switches positioned at each diagonal direction in the unit cell, activates the selected unit cell on the display, and inputs the corresponding key values by means of any one switch of four switches included in the selected unit cell.</p> |
