Abstract

A tool for performing a computer action based on a user'"'"'s touch on a touch screen. The user'"'"'s touch is characterized by certain parameters which are compared to predefined parameters which correspond to the hand that was used to touch the screen and a specific computer action. If the parameters match, within a specific error tolerance, the computer action is performed.

Claims

1. A method for performing a computer action based on a user input on a touch screen of a computing system, the user input entered by a user by holding the computing system in a right or left hand and touching the touch screen with the other hand, the method comprising the steps of:

the computing system receiving the user input on the touch screen of the computing system, wherein the touch screen is capable of displaying information;

the computing system receiving a shape of the user input on the touch screen;

the computing system determining which hand is used to enter the user input on the touch screen;

the computing system receiving an angle of rotation of the computing system with respect to gravity during entry of the user input;

the computing system determining a specific computer action to perform, based on the specific computer action being associated with predefined input parameters corresponding, within a specific error tolerance, to;

the received shape of the user input on the touch screen,

the determined hand used to enter the user input on the touch screen, and

the angle of rotation of the computing system with respect to gravity during entry of the user input on the touch screen; and

the computing system performing the specific computer action.

2. The method of claim 1, wherein the step of the computing system determining which hand is used to enter the user input on the touch screen, comprises the steps of:

the computing system receiving an indication, from each sensor in a plurality of sensors on the computing system, whether the user is touching the sensor during the user input on the touch screen, wherein each sensor of the plurality of sensors is a proximity sensor;

the computing system receiving an indication of the orientation of the computing system during the user input on the touch screen; and

the computing system determining the hand used to enter the user input on the touch screen.

3. The method of claim 1, wherein the shape of the user input is an ordered list of points describing a path that forms the bounds of the input.

4. The method of claim 1, wherein the shape of the user input is an ordered list of two-dimensional geometric segments describing a path that forms the bounds of the input.

5. A computer program product for performing a computer action based on a user input on a touch screen of a computing system, the user input entered by a user by holding the computing system in a right or left hand and touching the touch screen with the other hand, the computer program product comprising:

one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more storage devices, the program instructions comprising;

program instructions to receive the user input on the touch screen of the computing system, wherein the touch screen is capable of displaying information;

program instructions to receive a shape of the user input on the touch screen;

program instructions to determine which hand is used to enter the user input on the touch screen;

program instructions to receive an angle of rotation of the computing system with respect to gravity during entry of the user input

program instructions to determine a specific computer action to perform, based on the specific computer action being associated with predefined input parameters corresponding, within a specific error tolerance, to;

the received shape of the user input on the touch screen, and

the determined hand used to enter the user input on the touch screen; and

the angle of rotation of the computing system with respect to gravity during entry of the user input on the touch screen;

program instructions to perform the specific computer action.

6. The computer program product of claim 5, wherein the program instructions to determine which hand is used to enter the user input on the touch screen, comprise program instructions to:

receive an indication, from each sensor in a plurality of sensors on the computing system, whether the user is touching the sensor during the user input on the touch screen, wherein each sensor of the plurality of sensors is a proximity sensor;

receive an indication of the orientation of the computing system during the user input on the touch screen; and

determine the hand used to enter the user input on the touch screen.

7. The computer program product of claim 5, wherein the shape of the user input is an ordered list of points describing a path that forms the bounds of the input.

8. The computer program product of claim 5, wherein the shape of the user input is an ordered list of two-dimensional geometric segments describing a path that forms the bounds of the input.

9. A computer system for performing a computer action based on a user input on a touch screen of a computing system, the user input entered by a user by holding the computing system in a right or left hand and touching the touch screen with the other hand, the computer system comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices and program instructions which are stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising;

program instructions to receive the user input on the touch screen of the computing system, wherein the touch screen is capable of displaying information;

program instructions to receive a shape of the user input on the touch screen;

program instructions to determine which hand is used to enter the user input on the touch screen;

program instructions to receive an angle of rotation of the computing system with respect to gravity during entry of the user input

program instructions to determine a specific computer action to perform, based on the specific computer action being associated with predefined input parameters corresponding, within a specific error tolerance to;

the received shape of the user input on the touch screen, and

the determined hand used to enter the user input on the touch screen; and

and the angle of rotation of the computing system with respect to gravity during entry of the user input on the touch screen;

program instructions to perform the specific computer action.

10. The computer system of claim 9, wherein the program instructions to determine which hand is used to enter the user input on the touch screen, comprises program instructions to:

receive an indication, from each sensor in a plurality of sensors on the computing system, whether the user is touching the sensor during the user input on the touch screen, wherein each sensor of the plurality of sensors is a proximity sensor;

receive an indication of the orientation of the computing system during the user input on the touch screen; and

determine the hand used to enter the user input on the touch screen.

11. The computer system of claim 9, wherein the shape of the user input is an ordered list of points describing a path that forms the bounds of the input.

12. The computer system of claim 9, wherein the shape of the user input is an ordered list of two-dimensional geometric segments describing a path that forms the bounds of the input.
