Abstract

Touch sensitive mechanical keyboards and methods of configuring the depressibility of one or more keys of a keyboard are provided. A touch sensitive mechanical keyboard can accept touch events performed on the surface of the keys. Additionally, the keyboard can accept key depressions as textual input. The keyboard can be placed in a gesture operation mode, which can lock the keys to prevent a user from inadvertently depressing a key while attempting to perform a touch event on the surface of the keys. The keyboard can also be placed in a key press mode, which can allow depression of the keys by a user.

Claims

1. A keyboard comprising:

a plurality of keys, one or more of the keys being selectively depressible such that depression of the one or more keys is physically prevented by an actuator of the keyboard in a gesture mode and the actuator moves in a key press mode to physically allow depression of the one or more keys; and

a touch sensor co-located with one or more of the keys for detecting touch events on the one or more keys.

2. The keyboard of claim 1, further comprising:

a plurality of actuators co-located with the one or more selectively depressible keys;

wherein one or more actuators are collapsible in the key press mode; and

wherein the one or more actuators are rigid in the gesture mode.

3. The keyboard of claim 2, wherein the rigidity of the one or more actuators in the gesture mode prevents the one or more keys from depressing, cambering, sliding, and rotating.

4. The keyboard of claim 2, wherein the one or more actuators comprise a shape-memory material.

5. The keyboard of claim 2, wherein the one or more actuators comprise an electromechanical device.

6. The keyboard of claim 2, wherein the one or more actuators comprise a magnetorheological fluid.

7. The keyboard of claim 2, wherein the touch sensor is situated between the one or more keys and the one or more actuators.

8. The keyboard of claim 1, wherein an operation mode of the keyboard is determined by a touch event detected by the touch sensor.

9. The keyboard of claim 8, wherein the touch event is the initiation of a gesture.

10. The keyboard of claim 1, further comprising a button for setting an operation mode of the keyboard.

11. The keyboard of claim 1, wherein the keyboard is configured to allow depression of additional keys in the gesture mode.

12. The keyboard of claim 1, wherein the keyboard is incorporated within a computing system.

13. A method for configuring depressibility of one or more keys of a keyboard comprising:

determining an operation mode of the keyboard as a gesture mode;

in response to determining the operation mode as the gesture mode, configuring an actuator of the keyboard to physically prevent depression of the one or more keys that were previously depressible;

determining the operation mode of the keyboard as a key press mode; and

in response to determining the operation mode as the key press mode, moving the actuator to physically allow depression of the one or more keys.

14. The method of claim 13, further comprising:

detecting a touch event,

wherein the operation mode is determined based on the touch event.

15. The method of claim 14, wherein the touch event is the initiation of a gesture.

16. The method of claim 14, wherein the touch event is fingers resting on the keys in a home row configuration.

17. The method of claim 13, further comprising:

detecting a depression of a button on the keyboard,

wherein the operation mode is determined based on the depression of the button on the keyboard.

18. The method of claim 13, further comprising:

determining a status of a text input field on a device connected to the keyboard,

wherein the operation mode is determined based on the status of the text input field.

19. The method of claim 13, further comprising:

determining a default operation mode of the keyboard,

wherein the operation mode is determined based on the default operation mode.

20. The method of claim 13, wherein configuring the keyboard to physically prevent depression of the one or more keys includes configuring one or more actuators to be rigid.

21. The method of claim 20, wherein configuring the one or more actuators to be rigid includes stimulating the one or more actuators with an electric charge.

22. A non-transitory computer readable storage medium having computer-executable instructions stored therein, which, when executed by an apparatus including a keyboard, configures depressibility of one or more keys of the keyboard by causing the apparatus to perform a method comprising:

determining an operation mode of the keyboard as a gesture mode;

in response to determining the operation mode as the gesture mode, configuring an actuator of the keyboard to physically prevent depression of the one or more keys that were previously depressible;

determining the operation mode of the keyboard as a key press mode; and

in response to determining the operation mode as the key press mode, moving the actuator to physically allow depression of the one or more keys.

23. The non-transitory computer readable storage medium of claim 22, wherein the method further comprises:

detecting an initiation of a touch event,

wherein the operation mode is determined based on the initiation of the touch event.

24. The non-transitory computer readable storage medium of claim 22, wherein the method further comprises:

determining a status of a text input field on a device connected to the keyboard,

wherein the operation mode is determined based on the status of the text input field.

25. A computing system comprising:

a processor;

a memory; and

a keyboard;

wherein the keyboard comprises

a plurality of actuators,

a plurality of keys, one or more of the keys being selectively depressible such that depression of the one or more keys is physically prevented by one or more of the actuators in a gesture mode and the actuator moves in a key press mode to physically allow depression of the one or more keys, and

a touch sensor.
