BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a diagram showing a configuration of an apparatus for remotely controlling an electronic apparatus according to an embodiment of the present invention; FIG.

Referring to FIG. 1, an apparatus 100 for remotely controlling an electronic device according to an exemplary embodiment of the present invention includes a sensing unit 110, a range setting unit 120, a determination unit 130, and a control unit 140 .

The electronic apparatus according to the present disclosure may be an apparatus that performs an operation according to a user's control. For example, a smartphone, a tablet personal computer, a mobile phone, a videophone, an e-book reader, a desktop personal computer, a laptop personal computer, netbook computer, personal digital assistant, portable multimedia player (PMP), MP3 player, mobile medical device, electronic bracelet, electronic necklace, electronic apps, camera, Such as wearable devices, electronic clocks, wrist watches, home appliances such as refrigerators, air conditioners, vacuum cleaners, ovens, microwaves, washing machines, air cleaners, A magnetic resonance imaging (MRI), a computed tomography (CT), a camera, an ultrasound machine, etc.), a navigation system, Device, a GPS receiver em receiver, an event data recorder (EDR), a flight data recorder (FDR), a set-top box, a TV box (eg Samsung HomeSync ™, Apple TV ™, or Google TV ™) an electronic device, an electronic device, an electronic device, an electronic device, an infotainment device, an electronic equipment for ship (for example, a marine navigation device, a gyro compass, etc.), avionics, game consoles, head-mounted displays, flat panel display devices, electronic frames, electronic albums, furniture or parts of buildings / structures including communication functions, electronic boards, , An electronic signature receiving device or a projector, and the like.

The sensing unit 110 recognizes the user and recognizes the input gesture of the user. For example, the sensing unit 110 may include a proximity sensor. The proximity sensor determines whether the object containing the user is close to the electronic device. The proximity sensor is a sensor used for detecting and controlling the presence, passing, continuous flow, and rolling of an object using an electromagnetic field without physical contact. It is a high frequency oscillation system, a capacitance system, a magnetic system, a photoelectric system, an ultrasonic system The detection principle can be used.

For example, the proximity sensor may be a combination of a capacitive sensor (e.g., a sensor including a capacitor array), a proximity sensor, an IR sensor, an image sensor, an ultrasonic sensor, an electromagnetic induction sensor, a touch sensor, But it is not limited to the sensors listed above. For example, a touch sensor can operate as a proximity sensor by improving the sensitivity of the touch sensor.

For example, the sensing unit 110 may be an ultrasonic sensor that recognizes a sound wave having a frequency of 20 kHz or higher. The ultrasonic sensor can calculate the distance between the sensor and the object using the time difference between the sound waves transmitted and the reflected sound waves reflected by the object.

The range setting unit 120 may set a reference value that is a reference of a recognition range based on a user's recognition by the sensing unit 110 and may set a recognition range based on the reference value. Setting of the recognition range by the range setting unit 120 will be described later with reference to FIG. 2 to FIG.

The determination unit 130 may determine the input gesture of the user as the first motion and determine the input gesture of the user input in the different direction as the second motion. For example, when a user intends to control a change of a TV channel in a sofa by using a gesture in a living room environment in a home, a gesture in which a user's hand moves from left to right is determined as a first motion, The moving gesture can be determined as the second motion. In this case, the controller 140 controls the TV channel to be adjusted upward in response to the first motion, and controls the TV channel to be downwardly adjusted in response to the second motion. Alternatively, the determination unit 130 may determine the gesture in which the user's hand moves upward from below and the gesture in which the user's hand moves from the top to the bottom, respectively, as the second motion. In this case, the control unit 140 controls the volume of the TV to be adjusted upward in response to the first motion, and controls the volume to be adjusted downward in accordance with the second motion.

The determination unit 130 determines that the user's input gesture within the recognition range set by the range setting unit 120 is a valid gesture and determines that the user's input gesture outside the recognition range is an invalid gesture have. Therefore, it is possible to prevent the electronic device from being mis-controlled by an arbitrary movement of the user other than the user who intends to control the electronic device.

In addition, the determination unit 130 may determine whether the motion is a valid motion based on a distance generated by a user's input gesture. For example, it is determined that the first motion is determined by the input gesture but is not valid when the distance generated by the input gesture is less than a predetermined distance, and the distance at which the input gesture occurs is greater than a predetermined distance It can be determined to be valid. For example, a TV viewer can take other actions that are not intended as a motion during viewing, and can prevent erroneous control of the electronic device by determining such a small gesture as invalid.

2 is a diagram for explaining how an apparatus for remotely controlling an electronic device according to an exemplary embodiment of the present invention sets a range in which a user can sense an input gesture.

2, an electronic device 10 is shown, and the electronic device 10 may include a display portion 15. In addition, The display unit 15 may be formed of a liquid crystal display device, an organic light emitting diode, or the like, and may visually provide various menus, input data, function setting information, and the like of the electronic device 10 to a user. In addition, various information for informing the user of the operation state of the electronic device 10 can be displayed.

The electronic device control apparatus 100 may be attached to the front surface of the electronic apparatus 10 as a device separate from the electronic apparatus 10 and can be directed to the user 20 or may be a device included in the electronic apparatus 10 . In particular, the sensing unit 110, which may be, for example, an ultrasonic sensor, is positioned at the front of the electronic device 10 to recognize the user 20 and recognize the input gesture of the user 20, .

The sensing unit 110 may recognize the position of the user 20.

For example, the sensing unit 110 may recognize the position of the user 20 based on a manual input of the user 20. [ The user 20 performs the manual operation of pressing the button of the remote control to start the recognition of the position of the user 20 of the sensing unit 110 in the case of controlling the electronic device 10 which may be a TV in a living room environment in the home When the arm motion of the predefined pattern is performed, the sensing unit 110 can recognize the position where the motion occurs. The distance L to the position of the recognized user 20 can be set to a reference value and used to set the recognition range. On the other hand, when the user 20 changes the position, the user 20 can perform manual input again to set the changed reference value.

For example, the sensing unit 110 may automatically recognize the position of the user 20 without manually inputting the user 20. In the case of controlling the electronic device 10, which may be a TV in a living room environment in the home, the sensing unit 110 may count the number of occurrences of movement, and may calculate a distance L ) Can be set as a reference value. In this case, when the user 20 changes his / her position, the number of motions at that position will increase, so that the reference value can be automatically changed. In addition, a message indicating setting or changing of the reference value may be displayed on the display unit 15 of the electronic device 10 in order to display the setting or the change of the reference value to the user. The user 20 performs a remote control input for canceling a reference value setting or change in response to a message indicating setting or changing of a reference value displayed on the display unit 15 or generates a motion to set or change a reference value at an intended position Can be performed.

FIG. 3 is a diagram for explaining how an apparatus for remotely controlling an electronic device according to an exemplary embodiment of the present invention sets a range in which a user can sense an input gesture.

As described above, when the position of the user 20 is recognized by the sensing unit 110, the range setting unit 120 sets the distance L corresponding to the position of the user 20 to a shorter distance Position and a position distant by a predetermined distance can be determined as the recognition range 30. Since the constant interval is set to the recognition range 30 based on the reference value L, the recognition range 30 set in this embodiment will be a part of a circle or circle as shown in FIG.

4 is a diagram for explaining how an apparatus for remotely controlling an electronic device according to another embodiment of the present invention sets a range in which a user can sense an input gesture.

The recognition range 30 according to the present embodiment is linearized, unlike the recognition range composed of the circular or circular part shown in Fig. That is, in the case of controlling the electronic device 10, which may be a TV in a living room environment in the home, since the user generally sits on the couch and watches TV, this embodiment, which provides the linearized recognition range 30, Lt; RTI ID = 0.0 > environment. ≪ / RTI > When the position of the user 20 is recognized by the sensing unit 110, the range setting unit 120 sets the distance L corresponding to the position of the user 20 and the distance L from the front surface of the electronic device 10. [ It is possible to set the straightened recognition range 30 by using the angle with respect to the vertical line. For example, if the reference distance L to the user 20 is determined, the recognition range corresponding to the angle? May be determined as an area between (L-d) / cos? And (L + d) / cos?.

5 is a diagram for explaining how an apparatus for remotely controlling an electronic device according to another embodiment of the present invention sets a range in which a user can sense an input gesture.

The recognition range 30 according to the present embodiment is different from the linear recognition range shown in Fig. 4, and the range of the straight line is shortened. When the position of the user 20 is recognized by the sensing unit 110, the range setting unit 120 sets the distance L corresponding to the position of the user 20 and the vertical distance from the front of the electronic device 10 It is possible to set the recognition range 30 linearized by using the angle, and the angle can be limited to a specific angle by the user. For example, if the reference distance L to the user 20 is determined, the recognition range 30 may be set to correspond to a limited angle (e.g.,? = 30 占).

FIG. 6 is a diagram for explaining a method for remotely controlling an electronic device according to another aspect of the present invention, and for remotely controlling an electronic device according to a user's input gesture.

The electronic device remote control device 10 can set a recognition range 30 capable of recognizing the input gesture of the user 20 (S10). For example, the position of the user 20 can be recognized based on the manual input of the user 20, the distance L to the position of the recognized user 20 can be set as a reference value, A region between a position shorter by a predetermined distance and a position distant by a predetermined distance may be determined as the recognition range 30. [ For example, the position of the user 20 can be determined through a manual operation in which the user 20 presses a button on the remote control, or when the number of occurrences of the user's movement is counted and a movement of a predetermined number of times or more occurs, May be determined as the position of the user 20.

The electronic device remote control apparatus 10 can sense the input gesture of the user (S20), and the motion corresponding to the input gesture can be determined (S30). The input gesture of the user 20 may be determined as a first motion in one direction and a second motion in a direction different from the first direction. For example, when the user 20 intends to control the change of the TV channel with the gesture in the sofa in the home living room environment, the gesture in which the hand of the user 20 moves from left to right is determined as the first motion, The gesture in which the hand of the user moves from right to left can be determined as the second motion. As another example, the gesture in which the user's hand moves upward and downward can be determined as the first motion, and the gesture in which the user's hand moves from the top to the bottom can be determined as the second motion.

The electronic device remote control device 10 can control the function of the electronic device corresponding to the determined motion. For example, corresponding to the first motion in which the hand of the user 20 moves from left to right and from the right to the left, respectively, the TV channel is controlled to be adjusted upward and the TV channel can be controlled to be adjusted downward have. Alternatively, the volume of the TV can be controlled to be adjusted upward and the volume of the TV can be controlled to be adjusted downward, corresponding to the first motion in which the user's hand moves up and down and the second motion in which the top and bottom move upward and downward .

7 is a view for explaining a method of setting a range in which an apparatus for remotely controlling an electronic device can detect a user's input gesture according to another aspect of the present invention.

In this case, the controller 140 controls the TV channel to be adjusted upward in response to the first motion, and controls the TV channel to be downwardly adjusted in response to the second motion.

In this case, the control unit 140 controls the volume of the TV to be adjusted upward in response to the first motion, and controls the volume to be adjusted downward in accordance with the second motion.

7 is a view for explaining a method of setting a range in which an apparatus for remotely controlling an electronic device can detect a user's input gesture according to another aspect of the present invention.

The electronic device remote control device 10 can recognize the location of the user (S12). For example, when the user 20 performs a manual operation of pressing a button on the remote control to start recognition of a user's position and performs an arm operation of a predefined pattern, the position where the movement occurs can be recognized. Alternatively, the number of occurrences of the motion can be counted without the manual input of the user 20, and the position where the motion occurs can be recognized as the position of the user 20 when the counted number is greater than or equal to the predetermined number .

When the position of the user 20 is recognized, the distance from the electronic device remote control device 10 to the user 20 can be determined as a reference value (S14).

The electronic device remote control apparatus 10 can determine the recognition range of the input gesture (S16). The recognition range may be an area between a position that is shorter by a predetermined distance and a position that is a predetermined distance away from the reference value. Such a recognition range can be a part of a circle or a circle around an electronic device. This circular recognition range can be straightened using a distance corresponding to the position of the user 20 and an angle with respect to the vertical line from the front of the electronic device. Such a straightened recognition range may shorten the range of the straight line based on the angle restricted by the user.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features presented herein.
