Abstract

An improved handheld electronic device includes an input apparatus, an output apparatus, and a processor apparatus. The input apparatus includes a multi-axis input device such as a rollerball, trackball, joystick or touchpad, allowing the focus of a user interface program to be moved about a display from one screen object presented on that display to another. Up to four screen objects are presented on the display, each of those screen objects being positioned towards a corner of the display to enable a user to blindly operate the multi-axis input device, making use of a capture effect in which the focus of a user interface program is resisted from moving beyond an edge of the display, to guide movement of the focus to a given one of the up to four screen objects.

Claims

1. A handheld electronic device comprising:

a processor apparatus comprising a processor and a memory;

an input apparatus cooperable with the processor apparatus;

an output apparatus cooperable with the processor apparatus, the output apparatus including a display; and

a housing;

the processor apparatus being adapted to receive input from the input apparatus and to provide output to the display to present a plurality of screen objects, wherein a first screen object of the plurality of screen objects is positioned towards a corner of the display formed by two edges of the display;

the input apparatus including a multi-axis input device; and

the memory having stored therein a routine that is executable on the processor, wherein the routine is responsive to inputs from the multi-axis input device to move a focus of the routine from a second screen object of the plurality of screen objects to the first screen object, and wherein the routine creates a capture effect for the corner of the display by resisting the focus from being moved by the user beyond either of the two edges, the capture effect enabling the focus to be moved to the first object through blind operation of the multi-axis input device by a user of the handheld electronic device.

2. The handheld electronic device of claim 1 wherein the multi-axis input device is comprised of a movable portion that is translatable with respect to the housing to provide an input.

3. The handheld electronic device of claim 2 wherein the movable portion is substantially spherical.

4. The handheld electronic device of claim 2 wherein the input is a selection input to select an object to which the focus has been moved.

5. The handheld electronic device of claim 1 wherein the routine provides a visual indication of the focus having been moved to the first screen object.

6. The handheld electronic device of claim 5 wherein the visual indication is a highlight applied to the first screen object.

7. The handheld electronic device of claim 1 wherein the first screen object corresponds to an application, and wherein a movement of the focus to the first screen object and a selection input with respect to the first screen object causes the application to be executed by the processor.

8. The handheld electronic device of claim 1 wherein the first screen object corresponds to a piece of data, and wherein a movement of the focus to the first screen object and a selection input with respect to the first screen object causes the piece of data to be accessed with an application corresponding to the data type of the piece of data.

9. A method of enabling selection of a first screen object presented on a display of a handheld electronic device, the handheld electronic device including a housing, a processor apparatus, an input apparatus, and an output apparatus, the input apparatus including a multi-axis input device, the processor apparatus including a processor and a memory, the memory including a routine stored therein, the output apparatus including the display, the method comprising:

presenting the first screen object on the display at a position towards a corner formed by a first edge of the display and a second edge of the display;

detecting an input from the multi-axis input device;

responsive to said input, moving a focus of the routine from a second screen object presented on the display towards a quadrant that includes the corner in response to the input;

guiding movement of the focus to the first screen object by resisting movement of the focus beyond the first edge and the second edge; and

awaiting a selection input to select the first screen object.

10. The method of claim 9, further comprising detecting a selection input from the multi-axis input device and selecting the first screen object in response to the selection input.

11. The method of claim 9, further comprising associating the first screen object with an application to enable the application to be executed by the processor in response to the first screen object being selected.

12. The method of claim 9, further comprising associating the first screen object with a piece of data to enable the piece of data to be accessed with an application associated with the data type of the piece of data in response to the first screen object being selected.
