Abstract

A device and method for adjusting the target size of display images based on the detection of an input device is disclosed. The device (10) includes an input device detection circuit (56) operative to provide a detection signal (57) in response to the detection of an input device (36); and a device controller (50) operative to adjust the size of a target (16-26) presented on a display (14) in response to the detection signal (57). The method of the present invention includes detecting the presence of an input device; and adjusting the size of the targets present on a display in response to input device detection.

Claims

1. A method, comprising:

detecting a change in a presence or an absence of a non-finger input device within an input device holding chamber, wherein the detecting comprises providing a detection signal indicating whether or not the input device is present within the input device holding chamber; and

adjusting a size of targets presented on a display in response to the detecting, wherein the adjusting is based on the change in the presence or the absence of the input device within the input device holding chamber.

2. The method of claim 1, wherein adjusting the size of the targets includes resizing an aspect ratio of the targets.

3. The method of claim 1, wherein the targets are icons having scalable sizes.

4. The method of claim 1, wherein detecting the change in the presence or the absence of the input device includes detecting a state of an input device detection circuit.

5. The method of claim 4, wherein the input device detection circuit is a switch that alternates between a closed state and an open state.

6. The method of claim 5, wherein the targets each have a first size when the switch is in the closed state, and a second size when the switch is in the open state.

7. The method of claim 5, wherein the targets each have a first aspect ratio when the switch is in the closed state, and a second aspect ratio when the switch is in the open state.

8. The method of claim 5, further comprising providing a first layout when the switch is in the closed state.

9. The method of claim 5, further comprising providing a second layout when the switch is in the open state.

10. A method, comprising:

receiving a detection signal indicating a detection of a change in a presence or an absence of a non-finger input device within an input device holding chamber; and

adjusting a size of icons presented on a display in response to the receiving, wherein the adjusting is based on the change in the presence or the absence of the input device within the input device holding chamber, and wherein the icons are each presented in a first size or a second size.

11. The method of claim 10, wherein adjusting the size of the icons further includes presenting the icons in the first size when the detection signal indicates the detection of the input device.

12. The method of claim 10, wherein adjusting the size of the icons further includes presenting the icons in the second size when the input device is not detected.

13. A device, comprising:

a processor; and

a memory coupled to the processor, the memory including instructions that when executed cause the processor to;

(a) receive a detection signal representing a change in a presence or an absence of a non-finger input device within an input device holding chamber; and

(b) adjust a size of icons to be presented on a display in response to receiving the detection signal, wherein the adjusting is based on the change in the presence or the absence of the input device within the input device holding chamber.

14. The device of claim 13, wherein the detection signal is provided by an input device detection circuit located about the holding chamber operative to determine the presence of the input device.

15. The device of claim 14, wherein the input device detection circuit is a switch.

16. The device of claim 15, wherein the switch is one of:

a mechanical switch, an optical switch, a digital switch or a capacitance field.

17. The device of claim 13, wherein the memory further includes instructions that when executed cause the processor to swap a first screen layout for a second layout in response to receiving the detection signal.

18. A device, comprising:

an input device detection circuit operative to provide a detection signal in response to a detection of a change in a presence or an absence of a non-finger input device within an input device holding chamber, wherein the detection signal indicates whether or not the input device is present within the input device holding chamber; and

a device controller operative to adjust a size of a target presented on a display in response to the detection of the change in the presence or the absence of the input device within the input device holding chamber.

19. The device of claim 18, wherein the input device detection circuit is a switch.

20. The device of claim 19, wherein the switch is selected from the group consisting of:

a mechanical switch, an optical switch, a digital switch and a capacitance field.

21. The device of claim 18, wherein the device controller provides the target in a first size when the input device is detected within the input device holding chamber and a second size when the input device is not detected within the input device holding chamber.

22. The device of claim 18, wherein the device controller provides the target in a first aspect ratio when the input device is detected within the input device holding chamber and a second aspect ratio when the input device is not detected within the input device holding chamber.

23. A method, comprising:

detecting a change in a presence or an absence of a non-finger input device within an input device holding chamber, wherein the detecting comprises providing a detection signal indicating whether or not the input device is present within the input device holding chamber; and

changing from a first screen layout to a second screen layout presented on a display in response to the detecting, wherein the adjusting is based on the change in the presence or the absence of the input device within the input device holding chamber.
