Abstract

An electronic device utilizing an input component that is configured to receive various types of inputs is disclosed. The electronic device may include an enclosure including a top surface, a set of keys exposed on the top surface of the enclosure, and an input component. The input component may be a space bar included in the set of keys. Alternatively the input component may be a touchpad positioned adjacent the set of keys, which may not include a space bar. The input component is configured to receive or have various inputs performed thereon. The various inputs can include keypress inputs and touch-based gesture inputs. Additionally, the electronic device includes a process in electrical communication with the input component. The processing unit is configured to determine an input performed on the input component and subsequently provide a corresponding signal (e.g., keystroke signal, touch-based gesture signal) to the electronic device.

Claims

1. A portable computing device comprising:

an enclosure defining a top surface;

a set of keys extending through the top surface, the set of keys including a depressible key having a touch-sensitive surface and configured to actuate in response to a keystroke input;

a touchpad positioned along the top surface and along a side of the depressible key; and

a processing unit in electrical communication with the set of keys and the touchpad,

wherein;

the touchpad is configured to receive a first touch input having a first travel path along a surface of the touchpad;

the depressible key is configured to receive a second touch input having a second travel path along a surface of the depressible key; and

the processing unit is configured to;

determine whether the first touch input and the second touch input are portions of a single input; and

in response to determining that the first touch input and the second touch input are portions of the single input, invoke a touch-based command corresponding to the single input.

2. The portable computing device of claim 1, wherein:

the portable computing device is a notebook computing device;

the set of keys defines an alpha-numeric keyboard;

the depressible key is a space bar of the alpha-numeric keyboard; and

the space bar is positioned adjacent to a side of the touchpad.

3. The portable computing device of claim 2, wherein:

the space bar includes a capacitive sensor array configured to detect a location of a touch on a surface of the space bar; and

the space bar includes a force sensor configured to detect a force applied by the touch that exceeds a programmable threshold.

4. The portable computing device of claim 3, wherein:

the space bar is configured to invoke a keystroke command when the force applied by the touch exceeds an actuation threshold; and

the programmable threshold is less than the actuation threshold.

5. The portable computing device of claim 4, wherein the space bar is configured to actuate a dome switch when the touch exceeds the actuation threshold.

6. The portable computing device of claim 4, wherein the actuation threshold is programmably defined.

7. The portable computing device of claim 1, wherein:

the touch-sensitive surface of the depressible key defines multiple touch-sensitive regions; and

each touch-sensitive region is associated with a different function.

8. The portable computing device of claim 7, wherein the multiple touch-sensitive regions define four quadrant regions of the depressible key.

9. The portable computing device of claim 1, wherein the single input is configured to control a cursor of a graphical user interface.

10. The portable computing device of claim 1, wherein the processing unit is configured to determine that the first touch input and the second touch input are portions of the single input by determining that at least a portion of the first travel path is aligned with at least a portion of the second travel path.

11. A notebook computing device comprising:

an enclosure having an upper portion pivotally coupled to a lower portion;

a display positioned in the upper portion of the enclosure;

a touchpad positioned in the lower portion of the enclosure and having a first touch sensor configured to detect a first touch having a first travel path over a touchpad area;

a keyboard positioned along a side of the touchpad and including a space bar, the space bar configured to depress and comprising;

a second touch sensor configured to detect a second touch having a second travel path over a space bar area; and

a dome positioned below the space bar and configured to collapse when the space bar is depressed; and

a processing unit positioned in the lower portion of the enclosure and configured to;

determine whether the first touch and the second touch are portions of a touch input that extends across parts of both the touchpad area and the space bar area; and

in response to determining that the first touch and the second touch are portions of the touch input, invoke a command corresponding to the touch input.

12. The notebook computing device of claim 11, wherein the processing unit is further configured to:

determine if the second touch is a keypress or a gesture input; and

in accordance with the determination that the second touch is the gesture input, ignore an actuation of the space bar.

13. The notebook computing device of claim 12, wherein the determination is based on at least one of a duration of the second touch on a surface of the space bar or a duration since a previous keystroke was received by the keyboard.

14. The notebook computing device of claim 11, wherein:

the keyboard further comprises a force sensor configured to detect a force applied along the space bar area; and

in response to the force exceeding a first threshold, the notebook computing device is configured to initiate a touchpad press command; and

in response to the force exceeding a second threshold, the notebook computing device is configured to initiate a keystroke command.

15. The notebook computing device of claim 11, wherein the processing unit is configured to determine that the first touch and the second touch are portions of the touch input by determining that at least a portion of the first travel path is aligned with at least a portion of the second travel path.

16. An electronic device comprising:

an enclosure having an upper portion coupled to a lower portion;

a keyboard at least partially positioned within the lower portion of the enclosure and comprising a key configured to;

receive a first gesture input;

receive a second gesture input having a first travel path along a surface of the key; and

depress when actuated;

a touchpad positioned adjacent the key of the keyboard and configured to receive a third gesture input having a second travel path along a surface of the touchpad; and

a display at least partially positioned within the upper portion and configured to depict;

a cursor; and

a user interface for an application executing on the electronic device, wherein;

the second gesture input and the third gesture input manipulate a position of the cursor in response to a determination that the second gesture input and the third gesture input are portions of a single input; and

the first gesture input controls a function of the application.

17. The electronic device of claim 16, wherein:

the key is a space bar having a touch-sensitive surface configured to detect the first and second gesture inputs; and

the electronic device comprises a dome switch positioned below the key and configured to detect actuation of the key.

18. The electronic device of claim 16, wherein:

the determination that the second gesture input and the third gesture input are portions of the single input comprises a determination that a least a portion of the first travel path is aligned with at least a portion of the second travel path.
