Abstract

A method and device are described that provides for operating system independent gestures and a virtual keyboard in a dual screen device.

Claims

1. A method implemented by a dual screen device for operating system independent gestures, comprising:

detecting a touch point at one screen of the dual screen device;

determining the presence of a operating system independent gesture; and

initiating an action association with the operating system independent gesture.

2. The method of claim 1, wherein the detecting differentiates between finger based and shape based touches.

3. The method of claim 1, wherein the determining presence of the operating system independent gesture includes indicating to a user that the gesture is recognized.

4. The method of claim 3, wherein the indicating to a user that the gesture is recognized, initiates and places a virtual key board on the one screen of the dual screen device.

5. The method of claim 1 further comprising initiating a virtual keyboard that appears on the one screen.

6. The method of claim 5 further comprising placing applications present on the one screen to a second screen of the dual screen device, when the virtual keyboard appears.

7. The method of claim 1 further comprising providing for different user defined operating system independent gestures.

15. The dual screen device of claim 1 further comprising diverter logic than sends operating system controlled touch information to an operating system.

8. A dual screen device comprising:

one or more processors;

memory coupled to the processors;

a touch point recognizer that determines touch and shape information at one screen of the dual screen device.

a gesture recognizer that processes the touch and shape information, and determines a particular shape and associates the particular shape to an operating system independent gesture.

9. The dual screen device of claim 8, wherein touch point recognizer and gesture and gesture recognizer are part of a gesture engine that provides for customized operating system independent gestures.

10. The dual screen device of claim 8, wherein a virtual keyboard is initiated when the gesture recognizer recognizes a gesture associated with the virtual key board.

11. The dual screen device of claim 10, wherein one or more windows are moved from a first screen where the virtual keyboard appears to a second screen of the dual screen device.

12. The dual screen device of claim 10, wherein the virtual keyboard is centered on a first screen of the dual screen device, based on the gesture that is recognized.

13. The dual screen device of claim 10 further comprising tactile aides placed on the physical casing of the dual screen device.

14. The dual screen device of claim 13 wherein the tactile aides include one or more of the following on the front edge of the dual screen device:

a left edge indicator, a left bump indicator, a center rise indicator, a right bump indicator, and right edge indicator.

16. A method of initiating a virtual key and moving windows in a dual screen device, comprising:

determining a keyboard based gesture associated with the virtual keyboard from multiple point and shape based gestures;

moving the windows from a first screen to a second screen of the dual screen device;

initiating the virtual keyboard on the first screen; and

centering the virtual keyboard based on touch positions related to the keyboard based gesture.

17. The method of claim 16, wherein the determining the keyboard gesture is based on a two hands down gesture on the first screen.

18. The method of claim 16, wherein the moving the windows includes redisplaying the windows on the first screen, when the virtual keyboard is deactivated, the moving and redisplaying based on a Z-order of the windows relative to one another.

19. The method of claim 16, wherein the centering is based on finger positions and home row of the virtual keyboard.

20. The method of claim 16 further recognizing and differentiating one or more of the following shape based gestures:

two hands down, three finger tap, sweep, and grab.
