Abstract
A data entry system is provided using a virtual dynamic keypad having at least four keys, wherein to four of the keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined during the entry of text. A text entry system is also provided using a virtual keypad having at least four keys wherein to four of its keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined based on a calibrating procedure provided by the user. A data entry system is provided using a pointing device providing different pointing directions wherein each of the pointing directions duplicates a key of a predefined virtual keypad model wherein to at least some of its keys substantially all of the letters of a language are distributively assigned.
