Abstract

A method is provided for transforming ordered pairs of keystrokes entered on a keypad with eight or more keys into a full complement of alpha-numeric characters, as might be enterable from a computer keyboard. The method can be utilized with any device that permits an operator to select one of eight keys or other means of generating a distinct electrical or other signal. The keys or positions are arranged radially around a center point in locations corresponding to keys 1-4 and 6-9 of the telephone keypad. Examples of input devices include a numeric keypad, a telephone keypad, and a "joystick." The method employs an alphabet in which each character is represented by a two-stroke pictographic figure. The first stroke proceeds from the position of the first key to be pressed, thence to the center of the keypad or device. The second stroke proceeds from said center to a the position of the second key to be pressed. For the majority of letters, the figure thus formed bears a pictographic resemblance to the printed letter. The operator presses keys corresponding to the beginning and ending points of the pictograph of the desired character or key equivalent.

Claims

1. A method for entering alpha-numeric data from a data entry device, comprising the steps of

providing a data entry device having eight actuation points arranged in an array,

entering alpha-numeric data by entering sequential actuation points on the keys of the array, wherein the sequential keystrokes define pictographs, the pictographs having endpoints defined by the sequential keystrokes, each pictograph corresponding to a respective character of an alpha-numeric data set.

2. The method of claim 1 wherein the pictographs have a midpoint defined by a center point of the array.

3. The method of claim 1 wherein the array of eight actuation points comprise a first key, a second key, a third key, a fourth key, a fifth key, a sixth key, a seventh key, and an eighth key, the array defining a square in which the first, second and third keys define a first side of the square, the third, fifth, and eighth keys define a second side of the square, the sixth, seventh, and eighth keys defining a third side of the square, and the first, fourth, and sixth keys defining a fourth side of the square.

4. The method of claim 1, wherein each pictograph is defined by a pair of keystrokes.

5. The method of claim 1 wherein each pictograph which corresponds to a letter in the alphanumeric data set is defined by a first stroke passing from an actuation point to be actuated, to the center of the keypad, and a second stroke leading from said center to the second actuation point to be actuated.

6. The method of claim 1, wherein the data entry device is a telephone keypad, and the eight actuation points comprise keys 1,2, 3, 4,6, 7,8, and 9 on the telephone keypad.

7. The method of claim 1, wherein said eight actuation points are arranged radially around the center point so as to correspond to compass points of North, Northeast, East, Southeast, South, Southwest, West and Northwest.

8. The method of claim 1, wherein the data entry device is a joystick.

9. The method of claim 1, wherein the providing step further includes providing a ninth actuation point.

10. The method of claim 9, wherein the ninth actuation point is at a centerpoint of the array.

11. The method of claim 9, further comprising the step of activating a position control function when the ninth actuation point is actuated, the array of eight actuation points controlling movement of a position indicating member when the position control function is activated.

12. The method of claim 1, wherein one or more of the pictographs resemble the letters of the alphabet to which they correspond.

13. The method of claim 3, wherein the alphanumeric data set includes the following characters:

"q w e r t y u i o p a s d f g h j k l z x c v b n m,. Q W E R T Y U I O P A S D F G H J K L Z X C V B N M".

14. The method of claim 13, wherein the alphanumeric data set further includes the following characters:

"1 2 3 4 5 6 7 8 9 0,./<

>

?`;

15. A data entry device, comprising an array of eight actuation points, the data entry device defining an alphanumeric data set as a function of a sequential actuation of the actuation points, the data set including a plurality of characters, each character being defined by a sequential activation of no more than two actuation points, wherein said actuation points defining each character forming a corresponding pictograph, each pictograph having endpoints defined by the actuation point.

16. The method of claim 15 wherein each pictograph has a midpoint defined by a center point of the array.

17. The device of claim 15 wherein the array of eight actuation points comprise a first key, a second key, a third key, a fourth key, a fifth key, a sixth key, a seventh key, and an eighth key, the array defining a square in which the first, second and third keys define a first side of the square, the third, fifth, and eighth keys define a second side of the square, the sixth, seventh, and eighth keys defining a third side of the square, and the first, fourth, and sixth keys defining the fourth side of the square.

18. The device of claim 15 wherein each pictograph which corresponds to a letter in the alphanumeric data set is defined by a first stroke passing from a actuation point to be actuated, to the center of the keypad, and a second stroke leading from said center to the second actuation point to be actuated.

19. The device of claim 15, wherein the data entry device is a telephone keypad, and the eight actuation points comprise keys 1,2, 3, 4,6, 7,8, and 9 on the telephone keypad.

20. The device of claim 15, wherein said eight actuation points are arranged radially around the center point so as to correspond to compass points of North, Northeast, East, Southeast, South, Southwest, West and Northwest.

21. The device of claim 15, wherein the data entry device is a joystick.

22. The device of claim 17, further including a ninth actuation point at the center point of the array.

23. The device of claim 22, wherein the ninth actuation point, when actuated, causes the array of eight actuation points to control movement of a position indicating member.

24. The device of claim 23, wherein the position indicating member is a cursor.

25. The device of claim 15, wherein one or more of the pictographs resemble the letters of the alphabet to which they correspond.

26. The device of claim 15, wherein the alphanumeric data set includes the following characters:

"q w e r t y u i o p a s d f g h j k l z x c v b n m,. Q W E R T Y U I O P A S D F G H J K L Z X C V B N M".

27. The device of claim 15, wherein the alphanumeric data set further includes the following characters:
