Abstract

Touch typing on a telephone keypad is achieved by representing each letter as a combination of two separate symbols appearing on separate keys of a keypad. The keys may be operated by using the thumbs of both hands. In one embodiment, six symbols appearing on six separate keys are used to represent all of the letters A-Z. The six keys may be grouped together or may be split apart with one portion arranged on one side of a device display and another portion arranged on an opposite side of the display. Input may be accelerated in various ways using multiple key presses at the same time.

Claims

1. A method of controlling a mobile electronic device to receive text input, comprising, detecting presses of no more than N keys of some number of keys, receiving input of most or all of the letters A-Z of the alphabet by, for at least some letters, inputting that letter in response to exactly two sequential key presses.

2. The method of claim 1, wherein most or all of the letters are input in response to exactly two sequential key presses.

16. A method of user assistance for text input to a mobile electronic device having a keypad and a display, comprising displaying most or all of the letters A-Z, each letter being displayed as a combination of two separate symbols appearing on separate keys of the keypad.

17. The method of claim 16, wherein one symbol of said combination of two symbols is distinguished from the other using at least one of the following:

color, shading, line weight, dotting.

18. The method of claim 17, wherein said one symbol distinguished from the other is found on a key that is to be pressed first in order to enter a letter.

19. (canceled)

20. A method of controlling a mobile electronic device to receive graphical selection or cursor positioning information, comprising:

displaying an element on a display of the electronic device;

logically dividing the display into sections;

detecting a user input corresponding to a section of the display in which the display element is displayed;

logically dividing a section previously selected into smaller sections; and

repeating the immediately preceding steps of detecting and logically dividing as necessary.

21. The method of claim 20, further comprising indicating on the display said sections for selection by the user.

22. The method of claim 21, wherein the sections are quadrants.

23. The method of claim 20, wherein the user inputs are key presses or key combinations.

27. A keypad for use with a mobile electronic device, the keypad having an arrangement of keys, wherein respective keys have formed thereon respective indicia substantially as follows:

left angle, right angle, up angle, down angle, horizontal line, vertical line.

28. A keypad for use with a mobile electronic device, the keypad having an arrangement of keys, at least four of the keys having raised indicia formed thereon.

29. The apparatus of claim 28, wherein at least six of the keys have raised indicia formed thereon.

33. A mobile electronic device comprising a housing, a display and a keypad means having an arrangement of key means, wherein respective key means have formed thereon respective indicia substantially as follows:

left angle, right angle, up angle, down angle, horizontal line, vertical line.

34. The apparatus of claim 33, further comprising a controller for controlling said keypad means, the controller recognizing various sequences in which multiple key means are sequentially activated as representing various corresponding letters or symbols of an alphabet.

35. The method of claim 34, wherein for each of the letters of the English alphabet, each letters is represented by sequential activation of exactly two key means.
