BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and particular embodiments are illustrated in the drawings and will be described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terms first, second, etc. used in this specification may be used to describe various elements, but the elements should not be limited by terms. Terms are used only for the purpose of distinguishing one component from another.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. Referring to the drawings, substantially identical or corresponding elements are denoted by the same reference numerals, and a duplicate description thereof will be omitted do. In the drawings, the thickness is enlarged to clearly represent the layers and regions. In the drawings, the thicknesses of some layers and regions are exaggerated for convenience of explanation.

1 is a block diagram schematically illustrating an auditory inspection system according to an embodiment of the present invention.

Referring to FIG. 1, an auditory inspection system 10 according to an exemplary embodiment of the present invention includes a display unit 100, an audio output unit 200, a detection unit 300, and a control unit 400. The auditory inspection system 10 may further include an input unit 90 and a storage unit 500.

First, the display unit 100 is worn on the head of a subject to display an image. That is, the display unit 100 may be a head-mounted display (HMD) worn on the head of a subject. In one embodiment, the display unit 100 may display a virtual reality image to a subject. At this time, the display unit 100 uses a head-mounted display that provides a closed-view so as to block the examinee from the external reality background, thereby increasing the concentration of the subject and effectively displaying the virtual reality image to the subject .

The image displayed on the display unit 100 by the display unit 100 may be various forms such as a picture, a photograph, a text, a moving picture, a video, an application execution screen, and the like,

In one embodiment, the display unit 100 may display a surrounding image providing an image corresponding to a direction in which the subject's gaze is directed. More specifically, information on the eye direction of the subject detected by the detection unit 300 is transmitted to the control unit 400, and the control unit 400 controls the display unit 100 to display an image corresponding to the direction do. Here, the surrounding image refers to an image that is displayed in all directions (for example, front, back, left, right, up, and down directions) centering on the head-mounted display. Of course, the surround image is not limited to a spherical virtual reality image, and can be transformed into various types of virtual reality images such as cylinders and hemispheres according to a design. Thus, each time the examinee wearing the display unit 100 moves his / her head, images different from each other are displayed on the examinee so that the examinee can receive a more realistic virtual reality.

However, in order to implement the display unit 100 for auditory examination purposes, it is necessary to switch the image displayed on the subject when it is determined that the subject performs a meaningful operation. Since the display unit 100 displays the surround image in the present embodiment, the image displayed on the subject can be switched when the subject rotates the head by a predetermined angle. At this time, in order to sufficiently secure the range of the angle, it is more preferable to rotate the head to the left or to the right rather than rotate the head vertically.

In another embodiment, the display unit 100 may display an image different from the existing image when performing an operation such as button pressing, sound generation, etc. in addition to the operation of rotating the head of the examinee. This is because, regardless of whether the examinee rotates the head as in the above-described embodiment, the display unit 100 switches the displayed image even when the direction in which the subject's gaze is directed is fixed. The sound generation may be, but is not limited to, touching the subject or speaking a specific word.

As described above, while the display unit 100 displays an image to the examinee, the sound output unit 200 outputs a test sound for auditory examination to the examinee. The type of the test sound may be selected appropriately in consideration of the age and health condition of the subject, and the volume may vary depending on the result of the previous test when the test is repeatedly performed. In addition, the test sound may be a pure sound having a single frequency, a note (speech sound) corresponding to a speech or an environmental sound having a specific frequency characteristic.

The sound output unit 200 may include an earphone or a headphone. The subject 1 wears the display unit 100 in the form of a head-mounted display and the sound output unit 200 in the form of an earphone or a headphone, The virtual reality realized through the display unit 100 can be more easily immersed. However, the present invention is not limited to this, and the sound output unit 200 may be configured such that an examiner can hear an examination sound as well as an examinee, such as an external speaker.

The sound output unit 200 may include a left sound output unit 210 and a right sound output unit 220. The left sound output unit 210 outputs a left test sound for auditory examination of the left ear, The output unit 220 outputs a right test tone for auditory examination of the right ear. It is needless to say that the volume and type of the left test sound and the right test sound may be changed according to the result of the previous test.

The detection unit 300 detects a specific operation of the subject. Specifically, the detection unit 300 detects a behavior reaction operation such as a head turn of the subject with respect to the inspection sound direction when the inspection sound is output from the left sound output unit 210 or the right sound output unit 220 do. Hereinafter, embodiments of the detection unit 300 related to the image of the display unit 100 will be described in detail.

In one embodiment, the detection unit 300 may detect an operation in which the subject rotates the head by a predetermined range of angles. This corresponds to an embodiment in which the display unit 100 displays a surrounding image providing an image corresponding to the direction in which the subject's gaze is directed. In this case, it is preferable that the head of the examinee is rotated to the left or to the right rather than the top or bottom to ensure a sufficient range of the angle.

In this embodiment, since the operation of rotating the subject's head is a reaction operation to the test sound output from the sound output unit 200, the direction in which the examinee rotates the head means the direction in which the test sound is output. That is, when the left test sound is output from the left sound output unit 210, the examinee rotates the head to the left, and accordingly, the detecting unit 300 determines whether the examinee rotates the head to the left by a predetermined range of angles . Likewise, when the right test sound is output from the right sound output unit 220, the examinee rotates his / her head to the right, and accordingly, the detecting unit 300 determines whether the examinee rotates the head to the right by a predetermined range of angles .

Therefore, the detecting unit 300 of the present embodiment may include a gyro sensor that senses the rotational direction and rotational angle of the examinee's head. In order that the gyro sensor can operate effectively, the gyro sensor may be installed on the display unit 100 worn on the head of the subject. Thus, the gyro sensor can detect the rotation direction and the rotation angle of the examinee's head in real time when the subject's head is rotated.

As described above, when the detection unit 300 detects the rotation of the subject's head, the image displayed on the display unit 100 is converted to an image corresponding to the rotation direction and the rotation angle.

On the other hand, in the present embodiment, the operation for detecting is almost an instinctive operation by simply turning the head in the direction in which the examinee hears the examination sound, so that the present embodiment is not particularly limited to the age and can be sufficiently applied to children of low age .

In another embodiment, the detection unit 300 can detect a specific operation other than the operation of rotating the subject's head. This corresponds to the embodiment in which the display unit 100 displays an image different from the existing image irrespective of a change in the direction of the subject's gaze. That is, even if the examinee does not turn his / her head, the display unit 100 switches the displayed image when the subject performs an operation such as button pressing, sound generation, or the like.

In the case of this embodiment, the detection unit 300 can detect the operation of pressing the button. In addition to the above-described touching operation, the detecting unit 300 may be configured to detect the touch of the user, such as touching a finger or a specific word A sound generation operation can be detected.

As described above, when the detecting unit 300 detects the pushing operation of the button of the examinee, the image displayed on the display unit 100 is switched to an image different from the existing image.

On the other hand, the detecting operation in the present embodiment requires more cognitive ability and applicability of the subject than rotating the head, which is the detecting operation in the previous embodiment. Therefore, in the case of this embodiment, it may be effective to apply to a child older than the subject of the previous embodiment.

The display unit 100 and the sound output unit 200 described above are controlled by the control unit 400. [ That is, the control unit 400 controls the image displayed on the display unit 100 and the sound output from the sound output unit 200.

Specifically, when the detection unit 300 detects the reaction action when the subject performs a reaction action on the test sound output from the sound output unit 200, the control unit 400 displays the test sound on the display unit 100 Thereby converting the image from the first image to the second image. In consideration of the inspection result obtained through the control process, the controller 400 controls the test sound output unit 200, the display unit 100, and the like again so that the follow-up examination of the subject is continued. A more specific control method of the control unit 400 will be described later with reference to FIG. 2 and FIG.

The auditory inspection system 10 according to an embodiment of the present invention may further include an input unit 90 so that the control unit 400 can perform an appropriate control operation. In this case, the input unit 90 may be a portable electronic device such as a mobile communication terminal, and in this case, the input unit 90 may perform wireless communication with the control unit 400.

The input unit 90 is a portion for receiving inspection conditions according to the information of the examinee. Here, the information of the examinee may mean the age, history, etc. of the subject. In particular, since the auditory examination system 10 according to the embodiment of the present invention differs in the embodiments that are easy to be applied according to the age of the subject, the age of the subject is important in determining the examination condition input to the input unit 90 It can be an argument.

There are a variety of test conditions input to the input unit 90, but an inspection method according to the age of the subject can be input first. Specifically, when the subject is an infant less than three years of age, the subject selects the method of performing the auditory examination of the subject by detecting the motion of turning the head, and the subject is selected as a child of three to seven years of age The user can select a method of performing an auditory examination of the subject by detecting an operation of pressing the button or the like.

In addition, the input unit 90 may receive an operation mode, which means manual control or automatic control of the control unit 400. [ Accordingly, when the operation mode is input to the input unit 90 in consideration of the progress of the hearing test, the state of the examinee, and the like, the control unit 400 performs a control operation manually or automatically.

The input unit 90 may receive information such as the type of the image displayed on the display unit 100, the type of the test sound output from the sound output unit 200, and the volume of the test sound. In this case, the information may be selected differently depending on the age of the subject.

In this way, the controller 400 repeatedly performs the auditory test on the subject based on the inspection condition set through the input unit 90. The result of each auditory test or the final auditory test may be stored in the storage unit 500 have. At this time, the storage unit 500 may perform wireless communication with the control unit 400 as a portable electronic device such as a mobile communication terminal, in the same manner as the input unit 90. Although the input unit 90 and the storage unit 500 are shown as separate components in FIG. 1, the input unit 90 and the storage unit 500 are the same as each other. Lt; / RTI > device.

Specifically, the volume and output direction of the test sound and the reaction operation information of the testee with respect to the test sound can be stored in the storage unit 500. For example, when the examinee rotates his / her head to the left by an angle of a predetermined range when the left test sound is output from the left sound output unit 210, the storage unit 500 stores the information of the left test sound and the volume of the left test sound Information indicating that the examinee has responded to the left test sound, and the like.

As another example, when the storage unit 500 stores the final auditory test result, the storage unit 500 stores the final result obtained after the test is terminated because the reaction operation of the subject is no longer detected at a specific sound output sound pressure . Specifically, the storage unit 500 stores information on the left test sound or the right test sound, the minimum sound volume information of the left test sound / the right test sound detected by the reaction operation of the subject, the hearing threshold information of the subject, and the like .

At this time, the controller 400 may also analyze the inspection results to derive the inspection results or the final inspection results stored in the storage unit. That is, the control unit 400 analyzes the response / non-response / response of the test result each time, and calculates the hearing threshold value information of the examinee based on the minimum volume information at which the reaction operation of the subject is detected. Here, the term " forward reaction " means that, when the examination sound is output from the left sound output unit 210 or the right sound output unit 220, the subject rotates the head to the left or right by an angle of a predetermined range, . On the other hand, the non-response means that the examinee does not rotate the head by an angle of a predetermined range or presses the button so that the button is turned on even when the test sound is output. In addition, the above reaction means that the examinee rotates the head or presses the button even though the test sound is not output, the examinee rotates the head in the direction opposite to the output direction of the test sound, And the patient repeatedly shakes his or her head irrespective of the age of the subject.

Meanwhile, the information on the left / right side of the inspection sound and the volume of the inspection sound may be stored in the storage unit 500 through the control unit 400 as shown in FIG. 1, but the present invention is not limited thereto. ) In the storage unit 500 directly.

2 is a conceptual diagram schematically illustrating an auditory inspection system according to an embodiment of the present invention. Hereinafter, the contents overlapping with those described in the embodiments and modifications of the above-described auditory inspection system will be omitted or abbreviated.

Referring first to FIG. 2 and FIG. 1 described above, the subject 1 wears the display unit 100 in the form of a head-mounted display capable of displaying a virtual reality image on the head. The examinee 1 also wears a headphone or an earphone which functions as the sound output unit 200.

The input unit 90 is provided with an inspection method, an operation mode, a type of an image to be displayed on the display unit 100, and a type of an image displayed on the sound output unit 200 as inspection conditions according to the age of the examinee 1, The type and the volume of the inspection sound output from the control unit 20 are inputted. In the case of this embodiment, the examination condition in the case where the examinee 1 is an infant less than 3 years old can be inputted to the input unit 90. [

The first image IM1 is displayed on the display unit 100 before the inspection sound is output from the sound output unit 200. [ The first image IM1 may include a first object OB1 that shapes an animation character or the like preferred by the examinee 1, which is an infant younger than three years of age. Thereby, the examinee 1 is interested in the first object OB1, fixes his / her eyes on the first image IM1, and refrains from moving his / her head.

The sound output unit 200 outputs an audible sound for auditory examination to the examinee 1 while the visual line of the examinee 1 is directed to the first image IM1 of the display unit 100. [ At this time, when the examinee 1 listens to the output test sound, the examinee 1 turns his / her head in a direction in which the test sound is instinctively output, and the display unit 100, which the examinee 1 perceives, Is switched from the first image IM1 to the second image IM2.

Specifically, when the examinee 1 listens to the test sound in a state in which the left test sound is outputted from the left sound output unit 210, the examinee 1 determines the first test sound in a direction in which the left test sound is output, ). At this time, the detection unit 300 detects the reaction operation in which the examinee 1 rotates the head by the first angle? 1 to the left, and transmits the detection information to the control unit 400.

Thereafter, the control unit 400 controls the display unit 100 to display the left image IM21 corresponding to the first angle? 1 of the surround image. That is, the image displayed on the display unit 100 is switched from the existing first image IM1 to the left image IM21. Here, if the first angle? 1 is within a predetermined angle range, the displayed image may be the same as the left image IM21. The left image IM21 may be an image different from the first image IM1 and may include a second object OB21 different from the first object OB1 of the first image IM1, for example. The second object OB21 may also be an animation character preferred by the age group child of the examinee 1 and can instantaneously fix the line of sight of the examinee 1 like the first object OB1.

Thereafter, the control unit 400 analyzes whether the reaction operation information of the subject 1 received from the detection unit 300 is 'forward reaction', 'no reaction', or 'reaction above'. At this time, when the control unit 400 determines that the reaction operation information is 'normal reaction', the information of the left test sound, the volume information of the left test sound, and the information that the testee has reacted to the left test sound, As shown in Fig. The controller 400 can adjust the volume of the left test sound in the subsequent test based on the test result. Of course, the volume of the left test sound in the follow-up test is adjusted to be smaller than the volume of the previous output sound in the case that the 'normal reaction' is detected in the previous test, and when the 'no response' The volume of the output sound is adjusted to be larger than that of the output sound.

When the auditory examination of the left ear of the examinee 1 is finished in this way, the auditory examination of the right ear of the examinee 1 can be performed. When the right test sound is output from the right sound output unit 220 as in the above-described auditory test of the left ear, the examinee 1 rotates the head by the second angle? 2 in the direction in which the right test sound is output . At this time, the detection unit 300 detects the reaction operation in which the examinee 1 rotates the head by the second angle? 2 to the right, and transmits the detection information to the control unit 400.

The image displayed on the display unit 100 is switched from the existing first image IM1 to the right image IM22 under the control of the control unit 400. [ Here, if the second angle [theta] 2 is within a predetermined angle range, the displayed image may be the same as the right image IM22. The right image IM22 may be an image different from the first image IM1 and may include a second object OB22 different from the first object OB1 of the first image IM1, for example.

At this time, the second angle [theta] 2 for displaying the right image IM22 may have the same angular range as the first angle [theta] 1 for displaying the left image IM21. However, the present invention is not limited to this, and the angular range of the second angle [theta] 2 and the angular range of the first angle [theta] 1 may differ depending on the behavior of the examinee 1 and the physical condition.

The second object OB22 of the right image IM22 may be different from the second object OB21 of the left image IM21. This is because if the objects OB21 and OB22 are the same, the interest of the subject 1 is reduced when iterative inspections are performed and it may be difficult to obtain a sufficient effect of fixation of gaze. Therefore, the second object OB22 of the right- Is different from the second object OB21 of the left image IM21. Of course, the objects OB21 and OB22 may be the same as each other so long as there is sufficient eye gazing effect.

For the convenience of explanation, it is explained that the auditory examination of the right ear is performed after the auditory examination of the left ear. However, the auditory examination of the right ear is performed first and the auditory examination of the left ear is performed later, You can choose to do it anyway.

The controller 400 controls the volume, the number of times of output, and the output direction of the inspection sound output from the sound output unit 200 based on the information on the presence or absence of the reaction operation of the subject 1 received from the detection unit 300 To perform subsequent auditory tests repeatedly. After repeatedly performing the same or similar tests, the control unit 400 analyzes the test results and stores the final result including the hearing threshold value of the subject 1 in the storage unit 500.

3 is a conceptual diagram schematically showing a hearing examination system according to another embodiment of the present invention. Hereinafter, differences between the embodiments of the auditory inspection method and the modification examples described above with reference to FIG. 2 will be mainly described, but redundant contents of the previous embodiments and the like will be omitted or abbreviated.

Referring to FIG. 3 and FIG. 1 described above, the subject 1 wears on the head a display unit 100 in the form of a head-mounted display capable of displaying a virtual reality image, and functions as an acoustic output unit 200 Wear headphones or earphones. Further, the subject 1 can pinch a button device that can press the button when listening to the test sound. Of course, the button device does not necessarily have to be located on the body of the subject 1, but can be located anywhere that the subject of the subject 1 can reach. In addition to the above-mentioned button device, any device for detecting the reaction operation of the subject 1 can be used. For convenience of explanation, the detection unit 300 will be described specifically with reference to the case where the button device is provided as described above and the button pressing operation of the subject 1 is detected as a reaction operation to the inspection sound.

Prior to the start of the full auditory test, the input condition can be input to the input unit 90 when the subject 1 is an infant from 3 to 7 years old.

As shown in (i) of FIG. 3, the display unit 100 displays the first image IM1. This step means a step before the test sound is output from the sound output unit 200. [ The first image IM1 may include a first object OB1 that shapes an animation character or the like preferred by the examinee 1, who is an infant of 3 years of age or over but less than 7 years of age. Thus, the examinee 1 is interested in the first object OB1, and fixes his / her eyes on the first image IM1, so that he / she can concentrate on the auditory examination.

3 (ii), while the line of sight of the examinee 1 is directed to the first image IM1 in the display unit 100, the sound output unit 200 gives the examinee 1 auditory examination And outputs the test tone for the test. At this time, the subject 1 presses the button device provided in the detection unit 300, so that the image of the display unit 100 viewed by the subject 1 is read from the first image IM1 to the second image IM2, .

At this time, the second object OB2 included in the second image IM2 may be the same as the first object OB1 included in the first image IM1. That is, the second object OB2 of the second image IM2 may be a form in which the expression, operation, clothing, etc. of the first object OB1 of the first image IM1 are partially changed. Thus, the image displayed on the display unit 100 is implemented as an image similar to the animation, and thus it can be effective to induce the interest of the infant under the age of 7 years or over only. Therefore, the concentration of the audiometric test on the subject 1 of the above-mentioned age group can be further improved. However, the objects included in the first image IM1 and the second image IM2 are not necessarily the same, and the second object OB2 of the second image IM2, as in the previous embodiment shown in Fig. 2, May be different from the first object OB1 of the first image IM1.

The controller 400 controls the volume, the number of times of output, and the output direction of the inspection sound output from the sound output unit 200 based on the information on the presence or absence of the reaction operation of the subject 1 received from the detection unit 300 So that the subsequent auditory examinations are repeatedly performed. Based on the result, the final result regarding the hearing ability of the examinee 1 is derived from the control unit 400 and stored in the storage unit 500.

As described above, according to the embodiment of the present invention, it is possible to improve the concentration of infants and to increase the persistence and participation of the auditory test. In addition, the behavioral response of the child is objectified and accurate and rapid hearing test results can be obtained. In addition, it is possible to miniaturize the equipment required for hearing examination, thereby reducing the space limitation of the examination site and minimizing the number of examiners required for auditory examination.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art . Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
