Abstract

A display system includes: a user interface configured to detect a finger movement for detecting a finger movement on a trackpad; and a control unit, coupled to the user interface, configured to process a control for both a directional mode and a coordinate mode based only on the finger movement for controlling a device. The display system also includes a communication unit configured to receive a control for both a directional mode and a coordinate mode based only on a finger movement; and a control unit, coupled to the communication unit, configured to extract a directional command, a positional command, or a combination thereof from the control for controlling a device.

Claims

1. A display system comprising:

a user interface configured to detect a finger movement for detecting a finger movement on a trackpad; and

a control unit, coupled to the user interface, configured to process a control for both a directional mode and a coordinate mode based only on the finger movement for controlling a device.

2. The system as claimed in claim 1 wherein the control unit is configured to provide a directional command and a positional command from the control.

3. The system as claimed in claim 1 wherein:

the user interface configured to detect a first touch of the finger movement;

the control unit configured to form a grid of cells based on the first touch.

4. The system as claimed in claim 1 wherein the control unit is configured to:

form a grid of cells based on the finger movement;

determine a flick gesture with the finger movement within one of the cells; and

process the control includes to issue a directional command based on the flick gesture meeting or exceeding a flick threshold.

5. The system as claimed in claim 1 wherein the control unit is configured to:

determine a flick gesture with the finger movement; and

process the control includes to issue a directional command based on a contact length of the finger movement meeting or exceeding a contact length threshold.

6. The system as claimed in claim 1 wherein the control unit is configured to form a grid of cells based on the finger movement and each of the cells having a buffer zone.

7. A display system comprising:

a communication unit configured to receive a control for both a directional mode and a coordinate mode based only on a finger movement; and

a control unit, coupled to the communication unit, configured to extract a directional command, a positional command, or a combination thereof from the control for controlling a device.

8. The system as claimed in claim 7 wherein the control unit is configured to operate on an actionable item based on the directional command.

9. The system as claimed in claim 7 wherein the control unit is configured to move a cursor to a coordinate location based on the positional command.

10. The system as claimed in claim 7 wherein the control unit is configured to move a cursor to a coordinate location not related to an actionable item based on the positional command.

11. A method of operation of a display system comprising:

detecting a finger movement for detecting a finger movement on a trackpad; and

processing a control for both a directional mode and a coordinate mode based only on the finger movement for controlling a device.

12. The method as claimed in claim 11 wherein processing the control for both the directional mode and the coordinate mode includes providing a directional command and a positional command, respectively.

13. The method as claimed in claim 11 wherein:

detecting the finger movement include detecting a first touch;

further comprising;

forming a grid of cells based on the first touch.

14. The method as claimed in claim 11 further comprising:

forming a grid of cells based on the finger movement;

determining a flick gesture with the finger movement within one of the cells; and

wherein;

processing the control for both the directional mode and the coordinate mode include issuing a directional command based on the flick gesture meeting or exceeding a flick threshold.

15. The method as claimed in claim 11 further comprising:

determining a flick gesture with the finger movement; and

wherein;

processing the control for both the directional mode and the coordinate mode include issuing a directional command based on a contact length of the finger movement meeting or exceeding a contact length threshold.

16. The method as claimed in claim 11 further comprising forming a grid of cells based on the finger movement and each of the cells having a buffer zone.

17. A method of operation of a display system comprising:

receiving a control for both a directional mode and a coordinate mode based only on a finger movement; and

extracting a directional command, a positional command, or a combination thereof from the control for controlling a device.

18. The method as claimed in claim 17 further comprising operating on an actionable item based on the directional command.

19. The method as claimed in claim 17 further comprising moving a cursor to a coordinate location based on the positional command.

20. The method as claimed in claim 17 further comprising moving a cursor to a coordinate location not related to an actionable item based on the positional command.
