Abstract

Techniques are described herein that are capable of causing a control interface to be presented on a touch-enabled device based on a motion or absence thereof. A motion, such as a hover gesture, can be detected and the control interface presented in response to the detection. Alternatively, absence of a motion can be detected and the control interface presented in response to the detection. A hover gesture can occur without a user physically touching a touch screen of a touch-enabled device. Instead, the user'"'"'s finger or fingers can be positioned at a spaced distance above the touch screen. The touch screen can detect that the user'"'"'s fingers are proximate to the touch screen, such as through capacitive sensing. Additionally, finger movement can be detected while the fingers are hovering to expand the existing options for gesture input.

Claims

1. A method comprising:

detecting one or more fingers in a hover position, the one or more fingers being a spaced distance from a touch screen;

detecting a motion of at least one of the one or more fingers, the motion being a user command to present a control interface configured to control content associated with a virtual element that is displayed on the touch screen, the motion occurring without the at least one of the one or more fingers touching the touch screen; and

causing the control interface to be presented on the touch screen based on the motion.

2. The method of claim 1, wherein causing the control interface to be presented on the touch screen comprises:

transitioning from a first state in which the control interface is not shown on the touch screen to a second state in which the control interface is shown on the touch screen.

3. The method of claim 1, wherein causing the control interface to be presented on the touch screen comprises:

causing the control interface to change from a first state in which the control interface is partially transparent to a second state in which the control interface is opaque.

4. The method of claim 1, wherein causing the control interface to be presented on the touch screen comprises:

causing the control interface to change from a first state to a second state;

wherein, in the first state, the control interface is partially transparent to provide a first extent of transparency; and

wherein, in the second state, the control interface is partially transparent to provide a second extent of transparency that is less than the first extent.

5. The method of claim 1, wherein causing the control interface to be presented on the touch screen comprises:

causing the control interface to change from a first state in which a portion of the control interface is shown on the touch screen to a second state in which an entirety of the control interface is shown on the touch screen, the portion being less than all of the control interface.

6. The method of claim 1, wherein detecting the motion comprises:

detecting that the motion occurs for at least a specified period of time.

7. The method of claim 1, wherein detecting the motion comprises:

detecting a finger hover pan performed by the at least one of the one or more fingers.

8. The method of claim 1, wherein the at least one of the one or more fingers includes a plurality of fingers;

and

wherein detecting the motion comprises;

detecting that the plurality of fingers are moved together, or

detecting that the plurality of fingers are moved apart.

9. A system comprising:

a touch screen sensor configured to detect one or more fingers in a hover position, the one or more fingers being a spaced distance from a touch screen;

a gesture engine configured to detect a motion of at least one of the one or more fingers that occurs without the at least one of the one or more fingers touching the touch screen in response to detection of the one or more fingers, the motion being a user command to increase visibility of a control interface that is at least partially visible on the touch screen, the control interface configured to control content associated with a virtual element that is displayed on the touch screen; and

a rendering engine configured to cause the visibility of the control interface on the touch screen to increase based on the motion.

10. The system of claim 9, wherein the rendering engine is configured to cause the control interface to change from a first state in which the control interface is partially transparent to a second state in which the control interface is opaque.

11. The system of claim 9, wherein the rendering engine is configured to cause the control interface to change from a first state to a second state;

wherein, in the first state, the control interface is partially transparent to provide a first extent of transparency; and

wherein, in the second state, the control interface is partially transparent to provide a second extent of transparency that is less than the first extent.

12. The system of claim 9, wherein the rendering engine is configured to cause the control interface to change from a first state in which a portion of the control interface is shown on the touch screen to a second state in which an entirety of the control interface is shown on the touch screen, the portion being less than all of the control interface.

13. The system of claim 9, wherein the gesture engine is configured to detect a finger hover flick performed by the at least one of the one or more fingers.

14. The system of claim 9, wherein the gesture engine is configured to detect a high-velocity flick performed by the at least one of the one or more fingers, the high-velocity flick defined by the at least one of the one or more fingers traveling at a velocity that is greater than or equal to a threshold velocity.

15. The system of claim 9, wherein the gesture engine is configured to detect a finger hover circle performed by the at least one of the one or more fingers.

16. A computer program product comprising a computer-readable medium having computer program logic recorded thereon for enabling a processor-based system to cause a control interface to be presented on a touch screen, the computer program product comprising:

a first program logic module for enabling the processor-based system to detect one or more fingers in a hover position, the one or more fingers being a spaced distance from the touch screen;

a second program logic module for enabling the processor-based system to detect a user command to present the control interface configured to control content associated with a virtual element that is displayed on the touch screen, the user command characterized by the one or more fingers remaining in the hover position for at least a specified period of time and further characterized by the one or more fingers remaining motionless for at least the specified period of time; and

a third program logic module for enabling the processor-based system to cause the control interface to be presented on the touch screen based on detection of the user command.

17. The computer program product of claim 16, wherein the third program logic module comprises:

logic for enabling the processor-based system to cause a transition from a first state in which the control interface is not shown on the touch screen to a second state in which the control interface is shown on the touch screen.

18. The computer program product of claim 16, wherein the third program logic module comprises:

logic for enabling the processor-based system to cause the control interface to change from a first state in which the control interface is partially transparent to a second state in which the control interface is opaque.

19. The computer program product of claim 16, wherein the third program logic module comprises:

logic for enabling the processor-based system to cause the control interface to change from a first state to a second state;

wherein, in the first state, the control interface is partially transparent to provide a first extent of transparency; and

wherein, in the second state, the control interface is partially transparent to provide a second extent of transparency that is less than the first extent.

20. The computer program product of claim 16, wherein the third program logic module comprises:

logic for enabling the processor-based system to cause the control interface to change from a first state in which a portion of the control interface is shown on the touch screen to a second state in which an entirety of the control interface is shown on the touch screen, the portion being less than all of the control interface.
