Abstract

A method and system for providing absolute coordinate mapping using zone mapping input in a vehicle includes determining a touch input received on a touchpad located in the vehicle, presenting an absolute mapped position of the touch input on a display screen located in the vehicle, presenting one or more user interface objects on the display screen, and providing a plurality of display input zones corresponding to one or more user interface objects presented on the display screen. The method and system further include determining a user input to one of the one or more user interface objects presented on the display screen based on the absolute mapped position of the touch input on at least one of the one or more user interface objects presented on the display screen, and the plurality of display input zones on the display screen.

First claim

The invention claimed is:

1. A method for providing absolute coordinate and zone mapping between a touchpad and a display screen which are separate and apart from one another, comprising:
presenting a plurality of user interface objects on the display screen at a location based on a first set of display coordinates, each user interface object associated with a first shape having a first proportion;
determining a set of active touchpad coordinates on the touchpad based on the first set of display coordinates; and
providing a plurality of touch input zones on the touchpad, each corresponding to one of the plurality of user interface objects presented on the display screen,
wherein each touch input zone includes a first area of a surface of the touchpad that corresponds to the set of active touchpad coordinates and a second area of the surface of the touchpad that is outside of the first area,
wherein each of the first areas of the touch input zones are set as a second shape associated with a second proportion different than the first proportion of the first shape,
wherein the first proportion of at least two of the plurality of user interface objects does not match the second proportion of the corresponding touch input zones by increasing the second proportion of at least one of the first areas of the touch input zones while decreasing a proportion for at least one second touch input zone;
wherein each touch input zone of different touch input zones on the touchpad correspond to one user interface object presented on the display screen.

2. The method of claim 1 , further including determining the touch input received at a portion of the surface of the touchpad and defining touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

3. The method of claim 2 , further including presenting an absolute mapped position of the touch input, wherein presenting the absolute mapped position includes determining display coordinates on the display screen that correspond to the touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

4. The method of claim 3 , wherein presenting the absolute mapped position of the touch input includes presenting an input indicator at a location of the display screen that includes the display coordinates on the display screen that corresponds to the touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

5. The method of claim 4 , wherein determining a user input to one of the plurality of user interface objects includes determining that the input indicator is presented on the first set of display coordinates, and display coordinates on the display screen that include a plurality of display input zones, each corresponding to one of the plurality of touch input zones.

6. The method of claim 1 , wherein providing the plurality of touch input zones on the touchpad, each corresponding to one of the plurality of user interface objects presented on the display screen includes determining a location of the second area of the surface of the touchpad based on a first measured distance that is determined to be the shortest from a second set of display coordinates that correspond to an edge of one of the plurality of user interface objects to a plurality of display coordinates at an edge of the display screen.

7. The method of claim 1 , wherein providing the plurality of touch input zones on the touchpad, each corresponding to one of the plurality of user interface objects presented on the display screen includes determining a location of the second area of the surface of the touchpad based on a second measured distance that is determined to be the shortest from a third set of display coordinates that correspond to a center point of one of the plurality of user interface objects to a plurality of display coordinates at an edge of the display screen.

8. The method of claim 1 , wherein providing the plurality of touch input zones on the touchpad, each corresponding to one of the plurality of user interface objects presented on the display screen includes determining touchpad coordinates that correspond to display coordinates that are determined to have a highest utilization likelihood, wherein the highest utilization likelihood is based on a shape and placement of each user interface object presented on the display screen.

9. A system for providing absolute coordinate and zone mapping between a touchpad and a display screen which are separate and apart from one another, comprising:
a memory storing instructions that when executed by a processor cause the processor to:
present a plurality of user interface objects on the display screen at a location based on a first set of display coordinates, each user interface object associated with a first shape having a first proportion;
determine a set of active touchpad coordinates on the touchpad based on the first set of display coordinates; and
provide a plurality of touch input zones on the touchpad, each corresponding to the one of the plurality of user interface objects presented on the display screen,
wherein each touch input zone includes a first area of a surface of the touchpad that corresponds to the set of active touchpad coordinates and a second area of the surface of the touchpad that is outside of the first area,
wherein each of the first areas of the touch input zones are set as a second shape associated with a second proportion different than the first proportion of the first shape,
wherein the first proportion of at least two of the plurality of user interface objects does not match the second proportion of the corresponding touch input zones by increasing the second proportion of at least one of the first areas of the touch input zones while decreasing a proportion for at least one second touch input zone;
wherein each touch input zone of different touch input zones on the touchpad correspond to one user interface object presented on the display screen.

10. The system of claim 9 , further including determining the touch input received at a portion of the surface of the touchpad and defining touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

11. The system of claim 10 , further including presenting an absolute mapped position of the touch input, wherein presenting the absolute mapped position includes determining display coordinates on the display screen that correspond to the touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

12. The system of claim 11 , wherein an input indicator is presented at a location of the display screen that includes the display coordinates on the display screen that correspond to the touchpad coordinates associated with the portion of the surface of the touchpad wherein the touch input is received.

13. The system of claim 12 , wherein the input indicator is presented on the first set of display coordinates, and display coordinates on the display screen that include a plurality of display input zones, each corresponding to one of the plurality of touch input zones.

14. The system of claim 9 , wherein the processor determines a location of the second area of the surface of the touchpad based on a first measured distance that is determined to be the shortest from a second set of display coordinates that correspond to an edge of one of the plurality of user interface objects to a plurality of display coordinates at an edge of the display screen.
