Referring to FIG. 3, the remote controller 10 according to the present invention is largely composed of a gyro sensor 12, a controller 13, a state display unit 14, and a signal transmitter 15.

The gyro sensor 12 serves as a position / acceleration sensor for detecting a movement (or vibration) of the remote controller 10 according to a user's manipulation. The gyro sensor 12 is a sensor for detecting an angular velocity using a vibration-corrected tuning fork. The gyro sensor 12 generates a rotational movement about a longitudinal axis of the sensor using a Coriolis effect at a DC voltage proportional to the rotational angle. Mainly used for motion control, 3D game machine, image stabilization device.

The controller 13 recognizes the movement pattern detected by the gyro sensor 12, and determines whether the recognized pattern is a movement pattern registered in the remote controller 10. As a result of the determination, when the recognized pattern is a movement pattern registered in the remote controller 10, the state display unit 14 indicates that the corresponding movement pattern is input. Then, a remote control signal corresponding to the recognized movement pattern is generated.

The signal transmitter 15 transmits a remote control signal generated from the controller 13 to a corresponding electronic device to be controlled remotely. Such a signal is transmitted in the form of a radio frequency (RF) signal or an infrared signal.

The status display unit 14 serves to inform that the movement pattern has been successfully input. To this end, the status display unit 14 may be configured as a sound generating device or a light emitting device, or may be configured as a small liquid crystal display (LCD) that displays an inputable pattern graphically.

Referring to FIG. 4, in the remote control method according to the present invention, when the user moves the remote controller 10 (step 110), the gyro sensor 12 detects the movement of the remote controller 10 and the remote controller 10. (Step 120). When the movement pattern of the remote controller 10 is recognized, the controller 13 determines whether the pattern is a pattern registered in the remote controller 10 (step 130). As a result of the determination in step 130, when the movement pattern is a pattern registered in the remote controller 10, a specific sound (for example, a beep sound) or a text is input through the status display unit 14 that the movement pattern is input. (Step 140). To this end, the remote controller 10 according to the present invention is provided with a speaker, a small LCD, or a light emitting device.

As such, when a predetermined movement pattern is input, a remote control signal corresponding to the input movement pattern is transmitted to the corresponding electronic device, and the electronic device is remotely controlled by the transmitted remote control signal (step 150).

As described above, the remote controller 10 according to the present invention generates a predetermined remote control signal by recognizing the movement of the remote controller 10 itself instead of the operation of the command input button provided in the remote controller 10. do. Therefore, the electronic device can be remotely controlled by the movement of the remote controller 10 without a separate command input key. In addition, the layout of the existing complicated input keys may have a simple structure such as a bar like FIG. 1 and FIG. 2.

In addition, the remote controller 10 according to the present invention may integrate and control not only one electronic device but a plurality of electronic devices. The method is as follows.

5 is a flowchart illustrating a remote control method according to another embodiment of the present invention. Referring to FIG. 5, in the remote control method according to the present invention, when the user moves the remote controller 10 (step 210), the gyro sensor 12 detects the movement of the remote controller 10 and the remote controller 10. In step 220, the movement pattern is recognized. When the movement pattern of the remote controller 10 is recognized, the controller 13 determines whether the pattern is a pattern registered in the remote controller 10 (step 230). As a result of the determination in operation 230, when the movement pattern is a pattern registered in the remote controller 10, it is determined whether the movement pattern is for selecting an arbitrary electronic device to be controlled remotely (operation 240).

As a result of the determination in operation 240, when the corresponding movement pattern is not for selecting an electronic device to be controlled remotely, a remote control signal corresponding to the movement pattern is transmitted to the recently selected electronic device (operation 250). As a result of the determination in step 240, when the corresponding movement pattern is for selecting an electronic device to be remotely controlled, it is determined whether the power of the electronic device is turned on (step 250).

As a result of the determination in step 250, when the selected electronic device is powered on, the corresponding electronic device is selected as the electronic device to be remotely controlled by the movement pattern (step 280). In operation 250, when the selected electronic device does not have power, the power of the electronic device is turned on (step 270), and the electronic device to be remotely controlled by the movement pattern is selected (step 280). As such, when the electronic device to be remotely controlled by the movement pattern is selected, the corresponding electronic device is remotely controlled by the input movement pattern, as described in steps 210 to 250 described above. Although not shown in the drawing, when the movement pattern is normally input as in the case of FIG. 4, a specific sound (for example, a beep sound) or text indicates that the movement pattern is input through the status display unit 14. Will be displayed.                     

FIG. 6 is a diagram illustrating an example of a movement pattern used to perform the method illustrated in FIGS. 4 and 5. Referring to FIG. 6, respective electronic devices, such as a TV, a VCR, and an audio, are divided into predetermined movement patterns that can distinguish each electronic device. For example, a TV is divided into a square shape, a VCR is its initial V shape, and audio is its initial a shape. In addition, operations performed in each electronic device may also be displayed by being divided into movement patterns as shown in FIG. 6. Such a pattern may be set and changed by an application included in a personal computer (PC) or a digital television, and a new pattern may be added. The pattern is set in association with the actual operation so that the user can easily recognize it, and each pattern can be clearly distinguished to prevent a malfunction. In addition, when controlling a device having a display such as a TV, or when the remote controller 10 is provided with a display device such as an LCD, the shape and operation of a pattern that can be input through the LCD provided in the TV or the remote controller may be Can be displayed.

7A and 7B illustrate an example of selecting and manipulating an electronic device through recognition of a specific movement.

First, referring to FIG. 6 and FIG. 7A, the series of movement patterns shown in FIG. 7A relates to an operation in which the user turns on (or selects) the TV and continuously moves a channel to the next channel twice.

For example, when a user picks up the remote controller 10 and inputs a pattern corresponding to the TV, the remote controller 10 sends a power ON signal to turn on the TV and internally sends the next signal. You are ready to send it to the TV. At this time, all the input commands are considered to be transmitted to the TV until a signal for selecting another electronic device is input. Therefore, when the user inputs a pattern for selecting the next channel, the channel of the TV is changed to the next channel.

6 and 7B, the series of movement patterns shown in FIG. 7B can be described by the user turning on (or selecting) the TV and turning up the volume, and the user turning on (or selecting) the audio volume of the audio. It relates to a continuous operation of reducing.

For example, when a user inputs a pattern corresponding to a TV while holding the remote controller 10, the remote controller 10 controls the TV to input all patterns until a movement pattern for selecting another electronic device is input. Use to At this time, when a movement pattern for selecting audio is input as shown in the drawing, the remote controller 10 transmits a power-on signal for turning on power to the audio and prepares to transmit the next signal to the audio internally. Therefore, when the user inputs a pattern for lowering the volume, the volume of audio, which is a recently selected electronic device, is reduced.

In the above, the remote control apparatus and method for remotely controlling the electronic devices used in the home, such as a TV, based on the motion recognition of the remote controller as an embodiment of the present invention has been specifically illustrated. The present invention can also be applied to remote control such as off and door lock.

In addition, the remote controller according to the present invention can be implemented by adding a recognition function moved to the existing remote controller, even if the bar structure as described above.

As described above, according to the remote control apparatus and method according to the present invention, the user can perform a remote control by recognizing the movement of holding the remote controller itself instead of a series of operations of pressing a button provided in the remote controller. Thus, it is possible to remotely control one or more electronic devices with a simple configuration without a complicated arrangement of buttons.

Further, according to the remote control apparatus and method according to the present invention, the electronic devices remotely controlled by the movement pattern and the remote control signals for remotely controlling these electronic devices are set and combined by the movement pattern of the remote controller. you can change it.
