Touch screen apparatus and digital equipment having the same, and command-input method thereof
First Claim
1. A method of controlling a touch screen, comprising:
- determining whether at least two input signals are inputted;
when it is determined that at least two input signals are inputted, determining relative positions of the input signals based on reference position information contained in the input signals;
retrieving an execution command based on the determined relative positions of the input signals; and
executing the retrieved execution,wherein the step of determining whether at least two input signals are inputted comprises the steps of;
determining whether a preset time is elapsed after an input signal is inputted to a touch screen;
when it is determined that the preset time is not elapsed, waiting for an input of another input signal to the touch screen; and
when it is determined that the preset time is elapsed, determining whether at least two input signals are inputted.

Abstract
The present invention relates to a touch screen apparatus and a method of inputting a user command through the apparatus. A touch screen apparatus of the present invention comprises an input unit 10 having a sensing unit 12 for recognizing user'"'"'s touches and converting the touches into electrical signals; a storage unit 30 for storing execution commands corresponding to relative positions of the successive touches; and a control unit 20 for receiving the signals from the sensing unit 12 and executing an execution command retrieved from the storage unit. According to the present invention constructed as such, a variety of execution commands can be inputted without using a pattern of touches rather than an input area narrowly partitioned in a screen space.

1. A method of controlling a touch screen, comprising:
-
determining whether at least two input signals are inputted; when it is determined that at least two input signals are inputted, determining relative positions of the input signals based on reference position information contained in the input signals; retrieving an execution command based on the determined relative positions of the input signals; and executing the retrieved execution, wherein the step of determining whether at least two input signals are inputted comprises the steps of; determining whether a preset time is elapsed after an input signal is inputted to a touch screen; when it is determined that the preset time is not elapsed, waiting for an input of another input signal to the touch screen; and when it is determined that the preset time is elapsed, determining whether at least two input signals are inputted.

2. A touch screen apparatus, comprising:
-
a display unit equipped with a touch-sensing unit; a storage unit to store commands; and a control unit configured to detect at least one touch input, and retrieve and execute a corresponding command based on whether the detected at least one touch input includes only one touch input or two or more successive touch inputs, wherein, when the detected at least one touch input includes the two or more successive touch inputs, the corresponding command is determined based on a position of a last touch input of the two or more successive touch inputs relative to a position of another of the two or more successive touch inputs, and wherein the two or more successive touch inputs are determined by determining whether a preset time is elapsed after a touch input to the display unit is detected; when it is determined that the preset time is not elapsed waiting for another touch input to the display unit; and when it is determined that the preset time is elapsed, determining whether the two or more successive touch inputs are detected. - View Dependent Claims (3, 4, 5, 6, 7)

8. A method of displaying data, comprising:
-
displaying data on a display unit equipped with a touch-sensing unit; determining whether at least two successive touch inputs are detected in sequence during a preset time via the touch-sensing unit; and when the at least two input signals are detected in sequence, executing a command for controlling the displaying, according to a position of a last touch input of the at least two input signals relative to a position of another of the at least two input signals, wherein the step of determining whether at least two successive touch inputs are detected in sequence comprises the steps of; determining whether a preset time is elapsed after a touch input to the display unit is detected; when it is determined that the preset time is not elapsed, waiting for another touch input to the display unit; and when it is determined that the preset time is elapsed, determining whether the at least two touch inputs are detected.

9. A portable terminal, comprising:
-
a display unit equipped with a touch-sensing unit; and a controller configured to; detect two or more successive touches on the display unit via the touch-sensing unit, wherein the two or more successive touches are determined by; determining whether a preset time is elapsed after a touch to the display unit is detected; when it is determined that the preset time is not elapsed, waiting for another touch to the display unit; and when it is determined that the preset time is elapsed, determining whether the two or more successive touches are detected; retrieve and execute a command based on relative positions of the two or more successive touches; determine whether a last touch of the detected two or more successive touches correspond to a long-time touch; and when the last touch of the detected two or more successive touches does correspond to the long-time touch, continue to execute the command until the long-time touch is released. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A portable terminal, comprising:
-
a display unit; a touch-sensing unit; and a controller configured to; detect two or more successive touches on the display unit via the touch-sensing unit, wherein the two or more successive touches are determined by; determining whether a preset time is elapsed after a touch to the display unit is detected; when it is determined that the preset time is not elapsed, waiting for an input of another touch to the display unit; and when it is determined that the preset time is elapsed, determining whether the two or more successive touches are detected, select a command among plural commands based on a number of the detected two or more successive touches and a relative position of the two or more successive touches, and execute the selected command. - View Dependent Claims (21)

22. A portable terminal, comprising:
-
a display unit; a touch-sensing unit; and a controller configured to; determine whether at least two input signals are inputted, when it is determined that at least two input signals are inputted, determine relative positions of the input signals based on reference position information contained in the input signals, retrieve an execution command based on the determined relative positions of the input signals, and executing the retrieved execution, wherein, in determining whether at least two input signals are inputted, the controller is configured to; determine whether a preset time is elapsed after an input signal is inputted to a touch screen, when it is determined that the preset time is not elapsed, wait for an input of another input signal to the touch screen, and when it is determined that the preset time is elapsed, determine whether at least two input signals are inputted.
