12-key QWERTY text entry method

Abstract

New QWERTY key layout text entry method, which is designed to allow users to achieve high-speed text entry such as alphabet, numbers and symbols, on relatively small-sized devices such as cellular phones, smart phones, IP phones, landlinc phones, PDAs, watches, remote controllers, game controllers, Karaoke controllers, car navigation controllers, single-hand use assistive PC keyboard and other devices. Three different characters arc assigned for each single keypad, and one extra character is assigned to the gap space in between two keypads, comprising manually operated two actuator elements beneath each keypad. Single key press operation at the position of left, right, or middle part of the key-top convert three different states including simultaneous activation of the two actuator elements. Single key press operation at the middle gap space area between two neighboring keypads generate additional unique state, by right side of actuator clement of left side keypad and left side of actuator clement of right side keypad arc simultaneously activated. Three keypads in a same row can generate total 11 unique states by single key press operation. 12-key device such as cellular phone, keys ( 1,2.3,4,5.6,7,8,9,O,*,#) in three columns by four rows, can adopt Standard QWERTY keyboard's key layout with this invention, such as 1st row [QWERTYUIOP@], 2nd row [ASDFGHJKL;' ], 3rd row [ZXCVBNM,. / ], 4th row [SHlFT, SPACE, ENTER], and also double the key entry to cover numbers and all standard symbols on QWERTY keyboard with SHIFT+ key operation. Furthermore, the existing multiple key press text entry method for standard phone number-alphabet key assignment such as [2abc] method can also achieve by single key press operation without changing key assignment by adopting this invention.
