Abstract

A computing device is described herein which collects input event(s) from at least one contact-type input mechanism (such as a touch input mechanism) and at least one movement-type input mechanism (such as an accelerometer and/or gyro device). The movement-type input mechanism can identify the orientation of the computing device and/or the dynamic motion of the computing device. The computing device uses these input events to interpret the type of input action that has occurred, e.g., to assess when at least part of the input action is unintentional. The computing device can then perform behavior based on its interpretation, such as by ignoring part of the input event(s), restoring a pre-action state, correcting at least part of the input event(s), and so on.

Claims

1. A computing device, comprising:

plural input mechanisms for responding to an input action, including;

at least one contact-type input mechanism for providing at least one contact input event that indicates contact with the computing device; and

at least one movement-type input mechanism for providing at least one movement input event that indicates one or more of orientation and motion of the computing device; and

an interpretation and behavior selection module (IBSM) configured to detect a type of the input action that has occurred using a combination of said at least one contact input event and said at least one movement input event.

2. The computing device of claim 1, wherein the computing device is a handheld computing device.

3. The computing device of claim 1, wherein said at least one contact-type input mechanism comprises a touch input mechanism for sensing contact of a hand with the computing device.

4. The computing device of claim 1, wherein said at least one movement-type input mechanism comprises one or more of an accelerometer and a gyro device.

5. The computing device of claim 1, wherein the IBSM is configured to repeatedly analyze contact input events and movement input events in a course of the input action to improve a level of confidence at which the IBSM detects the type of input action.

6. The computing device of claim 1, wherein the IBSM is configured to conclude that at least part of the input action is unintentional when said at least one movement input event exceeds a prescribed threshold.

7. The computing device of claim 6, wherein the input action is associated with picking up or setting down the computing device.

8. The computing device of claim 6, wherein the IBSM is configured to also conclude that said at least part of the input action is unintentional based on an output of a light sensor.

9. The computing device of claim 1, wherein the IBSM is configured to conclude that at least part of the input action is unintentional when said at least one movement input event exhibits noise-like motion characteristics indicative of operation of the computing device in a noisy environment.

10. The computing device of claim 1, wherein the IBSM is configured to conclude that at least part of the input action in unintentional due to unintentional movement that occurs during application or removal of a touch contact.

11. The computing device of claim 1, wherein the IBSM is configured to detect a type of gesture associated with the input action based on a combination of said at least one contact input event and said at least one movement input event.

12. The computing device of claim 1, wherein the IBSM is configured to determine whether the input action is associated with an unintentional application of a touch contact based on a determined orientation of the computing device.

13. The computing device of claim 1, wherein the IBSM is further configured to execute a behavior in response to detection of the type of the input action, and wherein, as one behavior, the IBSM is configured to reject at least part of said at least one contact input event when the IBSM determines that at least part of the input action is unintentional.

14. The computing device of claim 1, wherein the IBSM is further configured to execute a behavior in response to detection of the type of the input action, and wherein, as one behavior, the IBSM is configured to restore a prior state when the IBSM determines that at least part of the input action is unintentional.

15. The computing device of claim 1, wherein the IBSM is further configured to execute a behavior in response to detection of the type of the input action, and wherein, as one behavior, the IBSM is configured to correct an interpretation of said at least one contact input event to remove effects of said at least one movement input event when the IBSM determines that at least part of the input action is unintentional.

16. A method for controlling a computing device in response to unintentional movement of the computing device, comprising:

receiving at least one contact input event from at least one touch input mechanism in response to contact with the computing device in a prescribed manner;

receiving at least one movement input event from at least one movement-type input mechanism in response to movement of the computing device;

detecting a type of input action associated with the contact with the computing device based on said at least one contact input event and said at least one movement input event; and

rejecting at least part of said at least one contact input event when at least part of the input action is determined to correspond to an unintentional input action.

17. The method of claim 16, wherein the input action is associated with picking up or setting down the computing device
