Abstract

A touch-sensitive display screen has at least two input modes for touch input. In an absolute input mode, positional information is interpreted in an absolute sense: an on-screen object or cursor can be moved, selected or activated by tapping or touching the screen at the location of the object itself or at a desired location for the object. In a relative input mode, touch input provided on the display screen is interpreted in a manner similar to a virtual joystick or a virtual touchpad. In the virtual joystick relative mode, input is interpreted relative to a reference point on the screen. In the virtual touchpad relative mode, input is interpreted according to a direction of motion of a contact point.

Claims

1. A method for operating a computing device, the method being performed by one or more processors and comprising:

determining an input mode for operating the computing device;

in response to the computing device being operated in an absolute input mode;

receiving a user input on a touch-sensitive display screen of the computing device;

determining an absolute location of the user input; and

performing a first operation that includes at least one of (i) moving a cursor or a displayed object on the touch-sensitive display screen to the absolute location, or (ii) selecting an interface feature that is provided at the absolute location; and

in response to the computing device being operated in a relative input mode;

establishing a reference location on the touch-sensitive display screen;

receiving a user input at a second location on the touch-sensitive display screen;

comparing the second location with the reference location to determine a direction and a magnitude of a vector having a start point at the reference location and an end point at the second location; and

performing a second operation that includes causing the cursor or the displayed object to move on the touch-sensitive display screen by an amount corresponding to the direction and the magnitude of the vector.

2. The method of claim 1, wherein determining an input mode includes at least one of (i) receiving a user selection of the absolute input mode or the relative input mode, or (ii) determining the input mode based on content that is displayed on the touch-sensitive display screen.

3. The method of claim 1, wherein performing the second operation includes continuing to move the cursor or the displayed object on the touch-sensitive display screen by the amount corresponding to the direction and the magnitude of the vector until user input at the second location is completed.

4. The method of claim 1, further comprising, in response to the computing device being operated in the relative input mode:

receiving additional user input indicating that an object being in contact with the touch-sensitive display screen is moving from the second location to a third location; and

in response to receiving the additional user input, (i) comparing the third location with the reference location to determine a second direction and a second magnitude of a second vector having a start point at the reference location and an end point at the third location, and (ii) continuing to move the cursor or the displayed object on the touch-sensitive display screen by an amount corresponding to the second direction and the second magnitude of the second vector.

5. The method of claim 1, wherein establishing the reference location includes receiving an initial the user input at an initial location on the touch-sensitive display screen.

6. The method of claim 1, further comprising:

displaying a graphical indicator to identify the determined input mode.

7. The method of claim 1, further comprising:

in response to the computing device being operated in the relative input mode and subsequent to establishing the reference location on the touch-sensitive display screen, displaying an indication of the reference location.

8. The method of claim 1, wherein performing the second operation comprises performing an operation having a speed based on the direction and the magnitude of the vector.

9. The method of claim 1, wherein the computing device comprises at least one selected from the group consisting of:

a telephone;

a smartphone;

a personal digital assistant;

a computer;

a handheld computer;

a kiosk;

an input terminal; and

a remote control.

10. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, causes the one or more processors to:

determine an input mode for operating a computing device;

in response to the computing device being operated in an absolute input mode;

receive a user input on a touch-sensitive display screen of the computing device;

determine an absolute location of the user input; and

perform a first operation that includes at least one of (i) moving a cursor or a displayed object on the touch-sensitive display screen to the absolute location, or (ii) selecting an interface feature that is provided at the absolute location; and

in response to the computing device being operated in a relative input mode;

establish a reference location on the touch-sensitive display screen;

receive a user input at a second location on the touch-sensitive display screen;

compare the second location with the reference location to determine a direction and a magnitude of a vector having a start point at the reference location and an end point at the second location; and

perform a second operation that includes causing the cursor or the displayed object to move on the touch-sensitive display screen by an amount corresponding to the direction and the magnitude of the vector.

11. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to determine an input mode by at least one of (i) receiving a user selection of the absolute input mode or the relative input mode, or (ii) determining the input mode based on content that is displayed on the touch-sensitive display screen.

12. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to perform the second operation by continuing to move the cursor or the displayed object on the touch-sensitive display screen by the amount corresponding to the direction and the magnitude of the vector until user input at the second location is completed.

13. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to, in response to the computing device being operated in the relative input mode:

receive additional user input indicating that an object being in contact with the touch-sensitive display screen is moving from the second location to a third location; and

in response to receiving the additional user input, (i) compare the third location with the reference location to determine a second direction and a second magnitude of a second vector having a start point at the reference location and an end point at the third location, and (ii) continue to move the cursor or the displayed object on the touch-sensitive display screen by an amount corresponding to the second direction and the second magnitude of the second vector.

14. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to establish the reference location by receiving an initial the user input at an initial location on the touch-sensitive display screen.

15. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to display a graphical indicator to identify the determined input mode.

16. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to, in response to the computing device being operated in the relative input mode and subsequent to establishing the reference location on the touch-sensitive display screen, display an indication of the reference location.

17. The non-transitory computer-readable medium of claim 10, wherein the instructions cause the one or more processors to perform the second operation by performing an operation having a speed based on the direction and the magnitude of the vector.

18. The non-transitory computer-readable medium of claim 10, wherein the computing device comprises at least one selected from the group consisting of:

a telephone;

a smartphone;

a personal digital assistant;

a computer;

a handheld computer;

a kiosk;

an input terminal; and

a remote control.
