A virtual keyboard displayed on a touch screen of a conventional portable terminal will be described with reference to FIGS. 1A and 1B. BACKGROUND ART A large number of keyboards, such as a Windows 102 key, a 104-key keyboard, and the like have been developed and used on an actual computer keyboard. Among them, QWERTY keyboard is generally used as alphabet key (English or other language). On the other hand, the virtual keyboard ("virtual keyboard") displayed on the touch screen of the portable terminal does not use the keyboard layout of the computer keyboard due to the limited space of the touch screen, It is adjustable to fit on the screen. This is referred to in the present application as "virtual keyboard of computer keyboard layout" (including claims). More specifically, the alphabet key is used to maintain a keyboard layout (e.g., a QWERTY layout) of a computer keyboard, while the other keys are adjusted by adjusting the keyboard layout to fit a limited space of the touch screen. For example, in order to save the space of the touch screen, numeric keys ('1' to '0' keys) are not provided separately on the virtual keyboard, It is common to input while switching the input mode. Other function keys are also available, such as simplified or omitted keyboards.

FIG. 1A is an example of a virtual keyboard of a computer keyboard displayed on a touch screen of a conventional portable terminal. FIG. 1A schematically shows a virtual keyboard of a computer keyboard type keyboard of a commonly used portable terminal of Apple Inc. of the United States. Here, a character input key group (group) 216 having a plurality of character input keys for inputting characters, and a key for controlling the function when the character input key is input Quot;). More specifically, a Shift key 210 for inputting uppercase letters in English, a "Language selection key" 214 for selecting a language input mode such as English and Korean, and a mode for inputting numbers and symbols And a "number and symbol switching key" For example, even when a keyboard at the same position is input, a number or a symbol is input instead of an alphabet in a state where a number and a symbol are input by the number and symbol switching key 212 are selected. For example, in the case of alphabetic characters, pressing the Shift key 210 and pressing the alphabetic key sequentially inputs an uppercase alphabetic character. Of course, for example, a variety of variations such as pressing the alphabetical key while pressing the Shift key 210 or switching the state to Caps Lock mode by pressing the Shift key 210 twice in succession, and then inputting an uppercase letter are possible Do.

However, in the conventional virtual keyboard, the character input key control key is disposed at the lower portion (lower portion) of the virtual keyboard, and more specifically, the character input key control key is provided in the lower row or the lower row to be. The upper, lower, left, and right directions in the present application are upward, downward, leftward, and rightward directions when the touch screen screen of the portable terminal is viewed in plan view. In the present application, when the planar area of the keyboard is bisected vertically, the upper portion is referred to as the upper portion of the keyboard, and the lower portion thereof is referred to as the lower portion of the keyboard. The arrangement tendency of the above-described character input key control keys not only originates from the space utilization aspect of the touch screen but also has a strong side derived from the conventional computer keyboard and typewriter keyboard, And the like. However, in the case of the portable terminal, if the terminal is to be held with both hands and the thumb is to be input, the input operation is troublesome and troublesome because the user has to accurately aim and press the thumb with a lot of bends every time the character input key is pressed. For example, as shown in FIG. 1B, in order to input one number, the thumb is severely bent and the number / symbol switching key 212 is pressed to switch to the number / symbol input mode, and the desired number is input. Then, in order to return to the alphabet input mode again, it is necessary to return to the alphabet input mode by pressing the number and symbol switch key 212 again, and then input the desired alphabet. Repetition of this difficult process can cause fatigue of the fingers and cause the speed of the letter input operation to be slowed down.

Next, a virtual keyboard of a portable terminal according to an embodiment of the present invention will be described. 2 is a block diagram illustrating a main configuration of a portable terminal according to an embodiment of the present invention. 2, the terminal includes a memory unit 100, a control unit 102, and a touch screen 104, and the touch screen 104 includes an input unit 108 and a display unit 106.

In addition, the terminal may further include various components such as a mobile communication module, an internet communication module, a short-range communication module, an audio processing unit, a digital broadcast receiving module, and a camera module. However, since they are not directly related to the present invention, .

The display unit 106 displays various information or the like on the screen and informs the user of the information. For example, the display unit 106 may display a graphic user interface and information related to the status and operation of the terminal. You can also display a virtual keyboard that allows you to enter text. Specifically, the display unit may include an LCD (Liquid Crystal Display) or an OLED (Organic Light Emitting Diode).

The input unit 108 allows a user to input a command, and can input a command of a user through a touch operation using, for example, a virtual keyboard. Specifically, the touch panel may be configured to include a touch panel that detects a touch operation of the user.

The memory unit 100 may store various programs and data to be executed and processed in the terminal, including an operating system, and may include one or more nonvolatile memories and volatile memories.

The control unit 102 may be configured to include a processor such as a CPU (Central Processing Unit) or an AP (Application Processor), and controls the overall state and operation of the terminal. When the operating system of the terminal starts up, the control unit waits for a command input by the user. In particular, the user watches whether the user touches the touch screen to input a command and waits. A signal generated by the touch operation of the touch screen is transmitted to the controller, and the controller determines what the command corresponding to the signal is and performs the command.

Next, a virtual keyboard of a portable terminal according to another embodiment of the present invention will be described. As shown in FIG. 4A, in this example, a plurality of character input key control keys form one row, which is referred to as a 'character input key control key row' 300. More specifically, it includes a Shift key 210, a number and a symbol switching key 212, and a language selection key 214, which are arranged in a bilaterally symmetrical structure. The character input key control key row 300 is provided on the character input key group 216. Accordingly, the user can input various characters without bending the thumb with a large number of characters using the character input key control key provided on the keyboard. 4B, for example, when it is desired to input an uppercase letter P in English, the Shift key 210 provided in the character input key control key row 300 is conveniently pushed with the left thumb, and then the alphabet key is pressed with the right hand do. When a command is input by the key input, the corresponding signal is transmitted to the controller 102 of the portable terminal, and the controller 102 determines the content of the signal and displays a capital letter P corresponding to the command.

5, a modifier key such as a ctl key 217 and an alt key 218 may be added to a character input key control key row 300 provided at the upper part of the virtual keyboard, . In actual operation, if the user presses the ctl key 217 and then presses the alphabet P key, the control unit of the portable terminal recognizes the key input as a command to output a document, As shown in FIG.

In the above embodiment, numeric and symbol switching keys are provided for switching to numeric and symbol input mode. However, numeric switching keys for switching to a mode for inputting numbers and symbols for switching symbols into symbols A switching key may be separately provided. In the above embodiment, the English alphabet key is shown as an example of a character input key, but it may be a key for inputting characters in other languages including Hangul.

Although the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited thereto. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.
