Abstract

Disclosed are methods in a slider form factor device, and slider form factor devices, for ignoring a key depression when there is a change in the position of a first housing relative to a second housing that occurs between the key depression and the release of the key depression. The method may include detecting a key depression of the first housing, detecting a change in the position of the first housing relative to the second housing, and detecting a release of the key depression. The method may further include ignoring the key depression when there is a change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

Claims

1. A method in a mobile communication device having a first housing and a second housing, the first housing having an exterior face and including at least one input key, the first housing having a position relative to the second housing and configurable to be in-line with the second housing, and the first housing and the second housing being movable with respect to one another, the method comprising:

detecting a key depression of a key of the first housing;

detecting a change in the position of the first housing relative to the second housing;

detecting a release of the key depression; and

ignoring the key depression when there is a change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

2. The method of claim 1, wherein ignoring the key depression includes ignoring the release of the key depression.

3. The method of claim 1, wherein detecting a change in the position of the first housing relative to the second housing comprises:

determining a change in an activation state or a deactivation state of the device.

4. The method of claim 1, wherein detecting a change in the position of the first housing relative to the second housing comprises:

sensing a state of a hook switch of the device or of a spring latch of the device.

5. The method of claim 1, wherein the at least one input key is a touch sensitive surface.

6. The method of claim 1, wherein the at least one input key is a navigation key.

7. The method of claim 1, wherein the at least one input key is a soft key.

8. A method in a mobile communication device having a first housing and a second housing, the first housing having an exterior face and including at least one input key, the first housing having a position relative to the second housing and configurable to be in-line with the second housing, and the first housing and the second housing being movable with respect to one another to activate or deactivate the mobile communication device, the method comprising:

detecting a key depression of a key of the first housing;

monitoring whether there is a change in the position of the first housing relative to the second housing;

detecting a release of the key depression; and

processing instructions related to the key depression and the release of the key depression of the first housing when there is no change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

9. The method of claim 8, wherein monitoring a change in the position of the first housing relative to the second housing comprises:

determining a change in an activation state or a deactivation state of the device.

10. The method of claim 8, wherein monitoring a change in the position of the first housing relative to the second housing comprises:

sensing a state of a hook switch of the device or of a spring latch of the device.

11. The method of claim 8, wherein the at least one key is a touch sensitive surface.

12. The method of claim 8, wherein the at least one input key is a navigation key.

13. The method of claim 8, wherein the at least one input key is a soft key.

14. A mobile communication device having a first housing and a second housing, the first housing having an exterior face, the first housing having a position relative to the second housing and configurable to be in-line with the second housing, and the first housing and the second housing being movable with respect to one another, the device comprising:

a controller configured to process instructions;

at least one input key on the exterior face of the first housing, the at least one input key coupled to the controller;

a key depression detection module including instructions to detect a key depression of a key of the first housing;

a position change detection module including instructions to detect a change in the position of the first housing relative to the second housing;

a key release detection module including instructions to detect a release of the key depression; and

a determination module including instructions to ignore the key depression and the release of the key depression of the first housing when there is a change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

15. The mobile communication device of claim 14 wherein the determination module is further configured to process instructions related to the key depression and release of the key depression of the first housing when there is no change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

16. The device of claim 14, wherein a change in the position of the first housing relative to the second housing comprises a change in an activation state or a deactivation state of the device.

17. The device of claim 14, wherein a change in the position of the first housing relative to the second housing includes a change in a state of a hook switch of the device or of a spring latch of the device.

18. The device of claim 14, wherein the at least one key is a touch sensitive surface.

19. The device of claim 14, wherein the at least one input key is a navigation key.

20. The device of claim 14, wherein the at least one input key is a soft key.
