Abstract

A button for efficiently displaying indicia on a hand-held device. A button constructed according to a first embodiment includes a main section and an integral extension having indicia positioned thereon. A second embodiment includes a main body section having at least one end containing indicia. Both embodiments provide for the user to actuate the button while still maintaining visible contact with the indicia. The present invention may also include an active character position within the button in which indicia is cycled through by actuating the button. The value of the indicia displayed in the active character position may then be input by an enter function.

Claims

1. A push-button for use on a handheld device comprising a main section and an extension integral with and extending from said main section, said extension further including indicia positioned to be visible when said main section is concealed.

2. The push-button of claim 1, further including at least a second extension integral with and extending from said main section, said second extension including indicia positioned to be visible when said main section is concealed.

3. The push-button of claim 1, wherein said main section includes indicia.

4. The push-button of claim 1, further including a stylus point positioned is on the push-button.

5. The push-button of claim 1 wherein said extension and said main section each have independent and distinct shapes.

6. The push-button of claim 1, wherein said main section has a circular shape and said extension has a circular shape.

7. The push-button of claim 1, wherein said main section has a main surface area and said extension has an extension surface area, said main surface area being sized larger than said extension surface area.

8. The push button of claim 2, wherein said main section has a main surface area and said extensions each have an extension surface area, said main surface area being larger than each of said extension surface areas.

9. The push-button of claim 1, wherein a common peripheral edge extends around said main section and said extension.

10. A handheld portable device comprising:

an outer housing;

a display positioned on said outer housing for displaying input characters; and

a plurality of buttons positioned on said outer housing for inputting values into the device, each of said buttons having a main section and an extension connected with and extending from said main section, each of said buttons further including indicia positioned on said extension to be visible when said main surface area is concealed.

11. The device of claim 10, further including indicia positioned on said main section.

12. The device of claim 10, wherein actuation of said main section allows for said indicia to be displayed on said display.

13. The device of claim 10, wherein a majority of said buttons on the device have the same shape and size.

14. The device of claim 10, wherein said main section has a main section surface area and said extension has an extension surface area, said main section surface area being larger than said extension surface area.

15. The device of claim 10, wherein each of said plurality of buttons further includes a second extension integral with and extending from said main section.

17. The button of claim 16, wherein said button has a uniform geometric shape.

18. The button of claim 16, wherein said ends with said indicia comprises less than about 10 percent of the total surface area of the button.

19. The button of claim 16, wherein each of said ends includes indicia.

16. A button for use on a handheld portable device comprising:

a button having an outer edge, a center point, and at least one end positioned within said outer edge farthest from said center point; and

indicia visibly positioned within at least one of said ends adjacent to said outer edge, wherein concealment of a majority of the button within said outer edge allows for said indicia to remain visible.

20. A handheld portable device comprising:

an outer housing for containing components of the handheld portable device;

a display screen positioned within said outer housing for displaying messages; and

a plurality of input buttons spaced about said outer housing, each of said buttons having an outer edge, a center point, and at least one end positioned a distance farthest from said center point, said plurality of input buttons further including indicia visibly positioned within at least one of said ends adjacent to said outer edge, wherein concealment of a majority of the button within said outer edge allows for said indicia to remain visible.

21. The device of claim 20, wherein a majority of said buttons positioned on said outer housing have the same shape and size.

22. A button for inputting information into a device comprising an active character position for visibly displaying a plurality of indicia one at a time, wherein actuation of the button results in one of said plurality of indicia being visibly displayed within said active character position.

23. The button of claim 22, further including at least one non-active character position located on the button, each of said non-active character positions visibly displays one of said indicia.

24. The button of claim 23, wherein the button includes one active character position and three non-active character positions.

25. The button of claim 22, wherein the button includes a main section having a main surface area and an extension connected with and extending from said main section, said active character position being located within said extension allowing for said indicia displayed in said active character position to be visible when said main section is concealed.

26. The button of claim 25, wherein at least one non-active character position is located within said main section.

27. The button of claim 25, further including at least a second extension connected with and extending from said main section, said second extension including indicia positioned to be visible when said main section is concealed.

28. The button of claim 25, further including a stylus point positioned on said main section.

29. The button of claim 22, wherein said push-button is used on a wireless communication device.

30. The button of claim 22, wherein the button has an outer edge, a center point, and at least one end positioned within said outer edge farthest from said center point, said active character position being positioned adjacent to at least one of said ends.

31. The button of claim 30, wherein the button has a uniform geometric shape.

32. The button of claim 30, further including a non-active character position located away from said end.

33. A method of displaying and inputting information through a button of a device comprising the steps of:

assigning a plurality of values to the button with one of the values being active;

providing an active character position on the button and displaying an indicia corresponding to the active value within the active character position;

detecting a button actuation and in response thereto changing the active value of the button and displaying the indicia corresponding to the active value within the active character position; and

detecting actuation of an enter function and in response thereto entering the current active value into the device.

34. The method of claim 33, further including displaying the indicia corresponding to the active value on an extension of the button.

35. The method of claim 33, further including displaying the current value entered into the device on a display.

36. The method of claim 33, wherein the button has an outer edge, a center point, and at least one end positioned a distance within the outer edge farthest from the center point.
