1 is a block diagram of an embodiment of a mobile communication terminal capable of function control using a motion sensor according to an embodiment of the present invention.

Referring to FIG. 1, a mobile communication terminal capable of controlling a function using a motion sensor includes a display unit 110 for providing visual information to a user, a user interface 120 for receiving an input from a user, and transmission and reception for mobile communication. Module RF module 130 and the baseband processor 140, the voice processing unit 150 for inputting and outputting voice information through the microphone and the speaker, a memory for storing a program for the operation of the mobile terminal and the user's usage information ( In a general mobile communication terminal including a control unit 170 for controlling the functional blocks, the control unit detects the movement of the mobile communication terminal to enable operation control based on motion information of the mobile communication terminal. It further comprises a motion sensor 180 for transmitting to 170.

Looking at the configuration of the mobile communication terminal capable of function control using the motion sensor in more detail, first, the motion sensor 180 detects the movement of the mobile communication terminal and transfers the information to the controller 170. At this time, the detected motion information is defined as information having a direction and a magnitude. Here, the direction refers to the vertical, vertical, left and right horizontal and diagonal left and right up and down direction with respect to the center of the center of the mobile communication terminal, in the embodiment of the present invention will be described limited to the left and right horizontal and diagonal left and right direction. In addition, the magnitude of the movement is represented by a predetermined value representing the length. As described above, the motion sensor 180 detects the direction of the mobile communication terminal and the magnitude of the motion in the direction and transmits it to the controller 180 as motion information.

The motion sensor 170 for detecting such a movement can be implemented with various sensors, and the present invention illustrates the use of an acceleration sensor. The acceleration sensor used in the present invention senses the acceleration, vibration and shock of the object to detect the movement and is implemented using the application principle of the gyro.

The controller 170 controls the operation of the mobile communication terminal such as a call and data transmission and reception. In the present invention, the control unit 170 receives the motion information transmitted from the moved sensor 180, classifies the motion by using the received motion information, and maps the classified motion to a predetermined mapping preset in the memory 160. The predetermined function set according to the table is controlled to operate. Here, the predetermined functions include functions performed by the mobile communication terminal such as deleting a character in a text input window or deleting a sentence, inputting a sentence, and transmitting a written message.

Table 1 below illustrates a mapping table regarding the motion setting values proposed in the present invention and the functions of the corresponding mobile communication terminals.

number Motion settings  function One left side Small (below threshold) delete 2 left side Larger (above threshold) Delete entire sentence 3 Left diagonal Small (below threshold) menu 4 Left diagonal Larger (above threshold) Send message 5 right Small (below threshold) Confirm 6 right Larger (above threshold) Call out 7 Right diagonal Small (below threshold) message 8 Right diagonal Larger (above threshold) END

Looking at this, the mapping table can be divided into several parts for each direction, in the embodiment of the present invention illustrates the dividing into two sizes. That is, it may be detected depending on whether a predetermined threshold is exceeded and the threshold is exceeded. If there are several thresholds, it is obvious that it is possible to divide the size into more parts, so the detailed description thereof will be omitted.

Thus, in the embodiment of the present invention, the movement of interest is stored in the memory 160 as a movement setting value, the movement setting value being " 1) left small, 2) left large, 3) left diagonal small, 4) left Diagonally large, 5) right small, 6) right large, 7) right diagonal small, 8) right diagonal large ". The controller 170 may obtain the function information from the mapping table by associating the received motion information with the motion setting value and using the corresponding motion setting value.

The function information thus obtained is transmitted to the control unit 170, and the control unit 170 controls to perform operations such as deleting a character or a sentence, inputting a sentence, and transmitting a written message according to the transferred function information.

According to the present invention, the controller of the mobile communication terminal capable of controlling the function using the motion sensor receives the motion information detected by the motion sensor, classifies the motion using the input motion information, and stores the classified motion in the memory 160. The predetermined predetermined function is controlled to operate according to the predetermined predetermined mapping table stored in the "

Specifically, the process of comparing the motion information received from the motion sensor 180 with the mapping table by the controller 170 will be described below.

First, the controller 170 classifies the movement direction and the size of the mobile communication terminal based on the motion information received from the motion sensor 180. Here, the movement direction may be one direction in which the mobile communication terminal is moved among the left, right, horizontal, diagonal, left, and right four directions based on the center point of the mobile communication terminal proposed by the present invention, and the size of the movement is the mobile terminal. It becomes a predetermined numerical value which shows length.

The control unit 170 corresponds to the classified movements to the movement setting value and determines whether there is a match. If there is a matching value as a result of the determination, the function information of the matching value can be obtained from the motion setting value. Here, the function information includes functions performed by the mobile communication terminal such as deleting a character or a sentence in a text input window, inputting a sentence, and transmitting a written message.

The function information thus obtained is transferred to the controller 170, and the controller 170 controls to perform an operation according to the transferred function information.

The threshold value of the motion setting value, the function information, and the motion setting value proposed in the present invention may be changed according to a manufacturer and a user of the mobile communication terminal.

The memory 160 includes a read only memory (ROM), a random access memory (RAM), a voice memory, and the like for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal.

In the present invention, the memory 160 stores a program of the motion sensor 180 for detecting the movement of the mobile communication terminal, and a mapping table for comparing the motion information classified by the controller 170. In addition, a graphical user interface (GUI) that allows a user to change a setting of a mapping table is also stored. Here, the GUI (Graphical User Interface) is used when the user wants to change the setting of the mapping table arbitrarily or changes the already changed setting to the initial value displayed by the manufacturer of the mobile communication terminal. When the user requests a change to the setting of the mapping table, the controller 170 recognizes this and displays a graphical user interface (GUI) on the display 110.

There are two ways to change the setting of the mapping table, a method of changing a setting by a user input directly, and a method of inputting a setting displayed by a manufacturer. Here, when a method of changing a setting by directly inputting by a user is selected, the controller 170 displays a graphical user interface (GUI) on which the user can directly input a movement setting value and a predetermined function according to the display unit 110. do. The user may directly change the movement setting value and a predetermined function according to the displayed graphical user interface (GUI), and the controller 170 which receives the changed movement setting value and the predetermined function according to the changed movement setting value is input. And a predetermined function thereof are stored in the memory 160 as a mapping table. Using the stored mapping table, the controller 170 may control the function of the mobile communication terminal by movement.

When inputting the setting displayed by the manufacturer of the mobile communication terminal, the controller 170 receives the movement setting value displayed by the manufacturer of the mobile communication terminal and a predetermined function according thereto. The controller 170 may change the input motion setting value and a predetermined function according to the settings displayed by the mobile communication terminal manufacturer, and store the same as a mapping table to control the function of the mobile communication terminal with motion.

The display unit 110 displays various messages and the like under the control of the controller 170, and the display unit 110 displays a liquid crystal display (LCD), a thin film transistor (TFT), an organic electroluminescence (EL), and the like. It may be configured as.

In the present invention, the display unit 110 displays a graphical user interface (GUI) screen through which the user can directly change the setting of the mapping table. The user may change the setting of the mapping table by using a graphical user interface (GUI) displayed on the display unit 110, and input of setting change may be input by using the key button 230 of the user interface 120.

The user interface 120 includes a plurality of numeric keys and function keys, and outputs key input data corresponding to a key pressed by the user to the controller 170.

In addition, the mobile communication terminal typically performs wireless communication with the base station. For this purpose, the RF module 130 transmits / receives an RF signal with the base station through an antenna ANT. Then, the RF module 130 first converts the received RF signal into an intermediate frequency (IF) signal, outputs it to the baseband processor 140, and converts an IF signal input from the baseband processor 140 into an RF signal and transmits the signal. do.

The baseband processor 140 is a baseband analog ASIC (BAA) that provides an interface between the controller 170 and the RF module 130. The baseband processor 140 converts a baseband digital signal applied from the controller 170 into an analog IF signal. Applied to the RF module 130, and converts the analog IF signal applied from the RF module 130 to a digital signal of the baseband and applied to the control unit 170.

The voice signal processor 150 is connected to the microphone MIC and the speaker SPK, and receives a voice signal received from the microphone MIC when a call is connected through the RF module 130 and the baseband processor 140. The data is output to the controller 170, and the voice data input from the controller 170 is converted into an audible sound through the speaker SPK and output.

2 is a diagram illustrating an operation of a mobile communication terminal capable of controlling a function using a motion sensor according to an exemplary embodiment of the present invention.

Referring to FIG. 2, a mobile communication terminal applied to the present invention is divided into a main body 210 and a folder 220 as shown in the drawing.

The main body 210 includes various key buttons 230, a microphone 240, and a volume key 250. Looking at the configuration in detail, the key button 230 is provided with a button-type keypad (230a) to perform the basic function according to the operation mode of the terminal, and also to perform the operation mode function of the terminal body 210 Four-way adjustment key 230b consisting of up, down, left and right is provided.

The liquid crystal display 260 and the speaker 270 are installed in the folder 220. The hinge device 280 is configured between the main body 210 and the folder 220 to be rotatable upward from the main body 210.

Looking at the operation according to an embodiment of the present invention, first, the control unit 170 receives a text corresponding to the number or letter through the key button 230 from the user.

Subsequently, as shown in the figure, the mobile communication terminal is moved smaller (less than or equal to the threshold value) in the horizontal direction to the left (21). When the motion sensor 180 detects a motion of the mobile communication terminal, the motion sensor 180 transmits motion information to the controller. The controller 170 receiving the motion information classifies the motion information into a motion direction and a motion size, and classifies the classified motion in response to a predetermined mapping table stored in the memory 160. Do this. In other words, it can be used to delete an incorrectly input character during input during text message creation.

In addition, when the mobile communication terminal is moved largely (over the threshold) in the horizontal direction to the left (22), an operation of deleting all texts, such as all previously entered text or numbers, which is a predetermined function set according to the mapping table is performed.

More specifically, an embodiment of the case of making a call will be described as follows.

If the user wants to dial the number 010-1234-5678, the user inputs the number to be dialed using the key button 230. If the number is incorrectly inputted as 010-1235 at the time of inputting the number, the user takes small (21) movement in the horizontal direction to the left in the center of the mobile communication terminal, thereby moving from the controller 170. Delete function can be performed. In addition, if a user inputs a number incorrectly from the beginning, such as 10-1234-5678, the user must delete the entire area. Above the threshold.) By performing the moving 22 operation, the entire entered number can be deleted. In the case of finally making a call, a call is performed by performing a moving 24 operation largely (above the threshold value) in the horizontal direction to the right.

In another embodiment, a method of creating and transmitting a text message is as follows.

When a user deletes an incorrectly written character or deletes an entire sentence when the user inputs a text message, the method is performed in the same manner as when the user makes a call. The sentence may be modified by using an operation corresponding to the deletion or the entire deletion. In this case, when the sentence is completed, the user may transmit a message by performing a 26 operation that moves larger (more than a threshold value) in the left diagonal direction, centered on the center of the mobile communication terminal.

In addition, the present invention can be used in parallel with the function of inputting letters or numbers using the existing voice recognition function. That is, when a sentence is input, a voice of a user input through a microphone is recognized, converted into text such as letters and numbers, and displayed on the display unit 110, and the corresponding movement proposed by the present invention is performed, and the existing voice recognition function and movement are performed. By using, it is possible to control the function of the mobile communication terminal.

Referring to FIG. 3, first, a mapping table regarding a movement of a mobile communication terminal is set by a manufacturer or a user of the mobile communication terminal (310). When the movement of the mobile communication terminal in which the mapping table is set is detected from the motion sensor 180 (320), the motion sensor 180 transmits the motion information to the controller 170. When the controller 170 receives the motion information from the motion sensor 180, the controller 170 classifies the received motion information into a motion direction and a motion size (330). The controller 170 maps the classified motion to the mapping table and determines whether there is a match (340). If there is a matching value as a result of the determination, the function information of the matching value can be obtained from the mapping table. Here, the function information includes functions performed by the mobile communication terminal such as deleting a character or a sentence in a text input window, inputting a sentence, and transmitting a written message.

The function information thus obtained is transferred to the control unit 170, and the control unit 170 controls to perform an operation according to the transferred function information (350).

If the motion information classified by the controller 170 does not match the motion setting value, the control returns to step 320.

Accordingly, the user may directly change the movement setting value and a predetermined function according to the graphical user interface (GUI) displayed on the display 110, and the controller 180 selects the user through the graphical user interface (GUI). A motion setting value and a predetermined function are received (operation 440).

The controller 170 receiving the changed motion setting value and the predetermined function according to the change is changed to the received motion setting value and the predetermined function and stored in the memory 160 as a mapping table (450). Using the stored mapping table, the controller 170 may control the function of the mobile communication terminal by movement.

When inputting the setting displayed by the manufacturer of the mobile communication terminal, the controller 170 receives the movement setting value displayed by the manufacturer of the mobile communication terminal and a predetermined function according to the operation (460). Here, the controller 170 stores the settings displayed by the manufacturer of the received mobile communication terminal as a mapping table (470).

By doing so, the user can easily set the mapping table directly without the inconvenience of directly inputting the mapping table, thereby controlling the functions of the mobile communication terminal by the movement.
