The chamber 100 may include a spacer 111, a ball 112, diaphragms 113-1 to 113-4, and fixing grooves 114-1 to 114-4.

The spacing 111 allows the ball 112 to move along the edge of the chamber 100 and to vibrate repeatedly in both directions in the diaphragms 113-1 to 113-4.

The movement of the ball 112 by the user vibrates the diaphragms 113-1 to 113-4 and moves along a specific path to stop the fixing grooves 114-1 to 114-4.

The fixing grooves 114-1 to 114-4 mean grooves that are more concave than the peripheral surface, and allow the moving ball to stop.

The sensor unit 120 serves to detect a movement pattern of the balls 112 moving by vibrating the diaphragms 113-1 to 113-4. The diaphragm includes an upper diaphragm 113-1, a lower diaphragm 113-2, a right diaphragm 113-3, and a left diaphragm 113-4, and is connected to the sensor unit 120.

The storage 140 stores the movement pattern of the ball 112 and the character set corresponding thereto, which can be described with reference to FIG. 2.

2 and 3 are schematic diagrams for explaining an example of a movement pattern and a character set corresponding thereto according to an embodiment of the present invention.

2 illustrates a movement pattern displaying consonants and a set of consonants corresponding thereto. Here, the movement pattern may be easily used by the user by using a form that matches the consonant set and the vowel set. That is, with respect to the movement pattern of the form of "a", it is possible to match the similar consonants "a, ㅈ, ㅊ, ㅋ".

If the ball 112 is moved in the form of "a" as shown in Figure 2 (a), the ball 112 is moved by vibrating the diaphragm in the order of the upper diaphragm 113-1, the right diaphragm 113-3. . The sensor unit 120 senses this, and outputs "AB" at the screen of the video display device as a consonant set corresponding to the "AB" movement pattern.

When the ball 112 is moved in the shape of “□” as shown in FIG. 2 (b), the ball 112 has an upper diaphragm 113-1, a right diaphragm 113-3, a lower diaphragm 113-2, and a left side. The vibration plate vibrates in the order of the vibration plate 113-4. The sensor unit 120 senses this and outputs "ㅁ, ㅂ, ㅇ, ㅍ, ㅎ" as a consonant set corresponding to the "□" movement pattern.

In this manner, FIG. 2 (c) outputs "b, c, b, s" as a consonant set corresponding to the "c" movement pattern, and FIG. 2 (d) corresponds to the "d" movement pattern. It outputs "ㄹ" as a set of consonants.

3 illustrates a movement pattern for displaying a vowel and a corresponding vowel set. When the ball 112 is moved in the form of "b" as shown in Figure 3 (a), the ball 112 is moved by vibrating the vibration plate in the order of the left diaphragm 113-4, the lower diaphragm 113-2. . The sensor unit 120 senses this and outputs "ㅏ, ㅑ, ㅗ, ㅛ" on the screen of the video display device as a collection set corresponding to the "b" movement pattern.

When the ball 112 is moved in the form of "b" as shown in Figure 3 (b), the ball 112 is moved by vibrating the diaphragm in the order of the upper diaphragm 113-1, the right diaphragm 113-3. . The sensor unit 120 senses this, and outputs "ㅓ, ㅕ, TT, ㅠ" on the screen of the video display device as a collection set corresponding to the "A" movement pattern.

In this manner, FIG. 3 (c) outputs "|" as a vowel set corresponding to the "ㅣ" movement pattern, and FIG. 3 (d) is a vowel set corresponding to the "＿" movement pattern. 3 (e) vibrates the right diaphragm 113-3 twice in succession with the movement pattern "∥", and displays "ㅐ, ㅒ, ㅔ, 영상" as a vowel set. Output on the screen of the device.

The signal output unit 130 reads the key value corresponding to the movement pattern detected by the sensor unit 120 from the storage unit 140. To output the read key value to the outside to convert the remote control signal corresponding to the key value. The remote control signal may be an infrared signal or an RF signal.

On the other hand, the character display as described above can be applied to not only Korean, but also English and numbers.

4 is a flowchart illustrating a text display method according to an embodiment of the present invention. When the text input mode key is selected (S410), the user can move the ball of the remote control. When the remote controller detects a movement pattern of the ball (S420), the remote controller transmits a remote controller signal for displaying a character set corresponding to the detected movement pattern (S430). The video display device displays the received character set in a predetermined region (S440). When the user selects a predetermined character, the selected character is displayed in the input window (S450).

Check whether there is a next character input (S460), when there is a next character input is switched to the state for the next character input (S470). When one character is entered, the cursor moves to the right of the entered character and blinks. When this condition is reached, the next character can be entered.

On the other hand, when there is no next character input, the input completed character is stored (S480). When the character input is completed, the character input mode key ends (S490).

5 is a flowchart illustrating a Hangul input according to an embodiment of the present invention. When the movement pattern of the ball is input (S510), the remote controller signal for displaying the consonant set corresponding thereto is transmitted (S515). When the movement pattern is input again (S520), it is checked whether the movement pattern is the same as the previously input movement pattern (S525).

When the same pattern is input as before, a remote controller signal for displaying a corresponding consonant set and a vowel set is transmitted (S530), and when a consonant is selected here (S535), the movement pattern is re-input (S520). Repeat the same operation. On the other hand, if the vowels other than the consonants are selected, it is checked whether there is a next movement pattern input (S540).

On the other hand, when it is different from the previously input movement pattern (S525), by transmitting a remote control signal for displaying a different collection set than the previous movement pattern (S545), it is checked whether there is an input of the next movement pattern (S540).

When the movement pattern is confirmed, a remote controller signal for displaying the corresponding consonant set is transmitted (S550), and it is checked whether there is no next character input (S555). On the other hand, if there is no movement pattern input, the process is terminated immediately, and when there is a next character input, the state is switched to a state in which the next character can be input, and the character is repeatedly completed from the first movement pattern input step.

6 is a schematic view for explaining a character display method according to an embodiment of the present invention. When a user wants to input a title by recording a TV program, the user may input the title on the TV screen through the text input mode of the remote controller to store the recorded data. When the user wants to input the title 'When the flowering spring comes', the user moves the ball by moving the remote controller according to the movement pattern assigned in the text input mode.

An input window 610 of the video display device 600 displays an input title. On the current screen, "flower blooming" is input, and the cursor 611 is blinking on the right side of "blood" to receive the next character input. If the movement pattern of the form "c" is inputted here, the key values "b, c, ㅌ, ㅅ" corresponding thereto are displayed on the selection window 620, and a character may be selected using the direction keys.

In order to display the values input to the current video display device 600, the ball of the remote controller is a pattern of movement of "ㄱ" → "ㄱ" → "b" → "ㄱ" → "□" → "ㅣ" → "c" Move along.

In detail, when the first input pattern "a" is input, the sensor unit detects the detected consonant set and the character set window "620" of the video display device 600 is detected. ). When the user selects "a", "a" is input to the input window 610 of the video display device 600.

When the second input has the same "a" movement pattern as the first input, the character selection window 620 corresponds to the consonant set "ㄱ, ㅌ, ㅊ, ㅋ" and the vowel set "ㅓ, ㅕ, ㅜ, ㅠ". Is aligned. Among these, when the user reselects "ㄱ", it is input as "ㄲ" in the input window 610. Next, when the input of "b" is input, the corresponding vowel set "ㅏ, ㅑ, ㅗ, ㅛ" is sorted, and if "ㅗ" is selected, the character is "co" in the input window 610. After inputting the word "ㄱ" as the fourth input, sort the values of the corresponding consonant sets "ㄱ, ㅈ, ㅊ, ㅋ". When there is an input, the cursor 611 moves to the right and waits for the next character input, in which way the next character can be input.

As described above, according to the present invention, the vibration sensor detects a ball movement inside the remote controller, and wirelessly transmits a corresponding key value to the video display device to display a character. As a result, a character is displayed on the screen of the video display device by a simple operation without the user pressing the buttons of the remote control keypad, thereby facilitating user convenience.
