Abstract

A method and system for providing a user interface for a handheld device that can be operated with one hand renders multiple items on the screen of the handheld device that are designed to match the footprint of a thumb or other finger. A user selects an item in the user interface by pressing it with their finger. The handheld interface system receives the user'"'"'s selection as an area of the screen that the user touched. The handheld interface system determines a probability that each of the multiple items rendered on the screen was the focus of the user'"'"'s selection. Then, the handheld interface system displays a subsequent screen based on the determined probability.

Claims

1. A method in a computer system of selecting items in a handheld device using a finger, the method comprising:

rendering multiple items on a screen of the handheld device;

receiving a selection of an area of the screen that indicates an area of the screen that was touched by the finger;

determining a probability that each item was the target of the selection; and

displaying a subsequent image based on the determined probability.

2. The method of claim 1 wherein the probability is based on the distance from the center of the area of the screen that was touched by the finger to the center of each of the multiple items.

3. The method of claim 1 wherein the probability is based on a majority area selected.

4. The method of claim 1 wherein the probability is based on the pressure applied within the area selected.

5. The method of claim 1 wherein rendering multiple items comprises rendering items with a size based on a probability of being selected.

6. The method of claim 1 wherein rendering multiple items comprises rendering items with a placement based on a probability of being selected.

7. The method of claim 1 wherein rendering multiple items comprises rendering items with a size based on pending actions for each item.

8. The method of claim 1 wherein rendering multiple items comprises rendering items with a size based on the number of children of each item in a hierarchy of items.

9. The method of claim 1 further comprising dynamically determining groups of items and wherein rendering multiple items is based on the determined groups.

10. The method of claim 1 wherein displaying a subsequent image comprises displaying an image containing a subset of the multiple items based on the probability that one of the subset of items was the target of the user'"'"'s selection.

11. A computer-readable medium containing instructions for controlling a computer system to display items in a user interface of a device based on the frequency of selection of the items, by a method comprising:

providing a group of items to render on a display;

determining a probability of being selected for each item in the group; and

rendering the items on the display in such a way that the items with the highest probability of being selected are easier to select than the items with a lower probability of being selected,

such that items can be selected by a user with one finger.

12. The computer-readable medium of claim 11 wherein determining a probability of being selected comprises determining the past frequency of selection.

13. The computer-readable medium of claim 11 wherein rendering the items on the display comprises determining the size and placement of the items.

14. A computer system for using a handheld device with one hand, comprising:

a render display component configured to render multiple items on a screen of the handheld device;

a receive input component configured to receive a selection of an area of the screen that indicates an area of the screen that was touched by a user;

a determine selection component configured to determine a probability that each item was the target of the selection; and

a select next display component configured to select a subsequent display based on the determined probability.

15. The system of claim 14 wherein the render display component is configured to render multiple items based on a selection by a user among multiple input methods.

16. The system of claim 15 wherein one of the multiple input methods is a stylus.

17. The system of claim 15 wherein one of the multiple input methods is a finger-based input method.

18. The system of claim 14 wherein the determine selection component determines the probability based on a majority area selected.

19. The system of claim 14 wherein the render display component-renders the multiple items with a size and placement based on the past frequency of selection of each item.

20. The system of claim 14 wherein the render display component dynamically determines groups of items and renders the items based on the determined groups.
