ABSTRACT:
A method and device for entering data is provided wherein the pressing of up to two combinations of proximate keys on a keypad concurrently sends a signal or signals from the keypad to a processor. The processor receives the signal or signals and identifies a character, symbol, or function associated with the signal or signals and reports the same. In one embodiment, the keypad used for entering the data has a configuration of three columns and four rows. A method of identifying a character, symbol, or function comprises comparing the signal or signals to a data set of associated characters, symbols, or functions wherein the data set is mapped to said signal or signals with a modified Braille cell.
