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.

a control unit, coupled to the user interface, configured to;

generate a grid of cells, including buffer zones between the cells, on a control device based on finger position on the trackpad, wherein

the grid of cells is for mapping finger movement to movement of a cursor, and

a size of the buffer zones is adjusted in response to movement granularity of the cursor corresponding to reduced sensitivity of the finger movement on the trackpad to prevent vacillation of the cursor when the cursor is between two of the cells,

process a control operating in either a directional mode and a coordinate mode determined based on the contact length, the acceleration, or a combination thereof of the finger movement for controlling a device,

wherein the directional mode is for moving the cursor in a discrete direction from a current item to a next item simultaneously displayed on a screen with the next item displayed along the discrete direction in relation to the current item, and

wherein the coordinate mode is for moving the cursor on the screen without constraint to the current item and the next item.

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 is configured to detect a first touch of the finger movement; and

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

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

form the 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 the 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 generate the grid of cells centered around detection of a first touch on the trackpad.

7. A display system comprising:

a communication unit configured to receive a control operating in either a directional mode and a coordinate mode determined based on a contact length, an acceleration, or a combination thereof of a finger movement; and

a control unit, coupled to the communication unit, configured to extract a directional command based on detection of the finger movement, on a grid of cells on a control device, representing a position on a trackpad, a positional command, or a combination thereof from the control for controlling a device, wherein;

the grid of cells is for mapping the finger movement to movement of a cursor and includes buffer zones between the cells and a size of the buffer zones is adjusted in response to a movement granularity of the cursor corresponding to the reduced sensitivity of finger movement on the trackpad to prevent vacillation of the cursor when the cursor is between two of the cells,

the directional command is for moving the cursor in a discrete direction from a current item to a next item simultaneously displayed on a screen with the next item displayed along the discrete direction in relation to the current item, and

the positional command is for moving the cursor on the screen without constraint to the current item and the next item.

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

9. The system as claimed in claim 7, wherein the control unit is configured to move the 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 the 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 the finger movement contacting on a trackpad, the finger movement corresponding to a contact length, an acceleration, or a combination thereof; and

generating a grid of cells, including buffer zones between the cells on a control device, based on finger position on the trackpad, wherein;

the grid of cells is for mapping the finger movement to a movement of a cursor, and size of the buffer zones is adjusted in response to a movement granularity of the cursor corresponding to reduced sensitivity of the finger movement on the trackpad to prevent vacillation of the cursor when the cursor is between two of the cells,
