Abstract

A terminal including a touch-screen display configured to be touched by a user, and a controller configured to determine a number of simultaneous touches on the touch-screen and to perform a function based on the determined number of simultaneous touches.

Claims

1. A terminal, comprising:

a touch-screen configured to receive a command from a user who touches the touch-screen; and

a controller configured to analyze the command in consideration of a number of simultaneous touches on the touch-screen,

wherein the command is a deletion command configured to delete at least one character displayed on the touch-screen by rubbing the character with a pointer, and the controller is configured to determine an area to be deleted in consideration of the number of the simultaneous touches, and

wherein the pointer is the user'"'"'s finger and the number of simultaneously touches includes the user touching the touch-screen with at least two fingers and then the controller automatically deletes at least one character on a first line based on one of the user'"'"'s fingers and deletes at least one character on a second line based on another one of the user'"'"'s finger.

2. A method for entering a command in a terminal equipped with a touch-screen, comprising:

receiving a command from a user who touches the touch-screen; and

analyzing the command in consideration of a number of simultaneous touches on the touch-screen,

wherein the command is a deletion command configured to delete at least one character displayed on the touch-screen by rubbing the character with a pointer, and the step of analyzing includes determining an area to be deleted in consideration of the number of the simultaneous touches, and

wherein the pointer is the user'"'"'s finger and the number of simultaneously touches includes the user touching the touch-screen with at least two fingers and the method further comprises automatically deleting at least one character on a first line based on one of the user'"'"'s fingers and deletes at least one character on a second line based on another one of the user'"'"'s finger.

3. A terminal, comprising:

a touch-screen configured to receive a command from a user who touches the touch-screen; and

a controller configured to analyze the command in consideration of a touched area on the touch-screen,

wherein the command is a deletion command configured to delete at least one character displayed on the touch-screen by rubbing the character with a pointer, and the controller is configured to determine an area to be deleted in consideration of the touched area of the pointer, and

wherein the pointer is the user'"'"'s finger and the number of simultaneously touches includes the user touching the touch-screen with at least two fingers and then the controller automatically deletes at least one character on a first line based on one of the user'"'"'s fingers and deletes at least one character on a second line based on another one of the user'"'"'s finger.

4. A method for entering a command in a terminal equipped with a touch-screen, comprising:

receiving a command from a user who touches the touch-screen; and

analyzing the command in consideration of a touched area on the touch-screen,

wherein the command is a deletion command configured to delete at least one character displayed on the touch-screen by rubbing the character with a pointer, and the step of analyzing includes determining an area to be deleted in consideration of the touched area of the pointer, and

wherein the pointer is the user'"'"'s finger and the number of simultaneously touches includes the user touching the touch-screen with at least two fingers and the method further comprises automatically deleting at least one character on a first line based on one of the user'"'"'s fingers and deletes at least one character on a second line based on another one of the user'"'"'s finger.
