In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

The terms first, second, etc. used herein may be used to describe various components, but the components should not be limited by the terms. The terms are only used to distinguish one component from another.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings, and in the following description with reference to the drawings, substantially identical or corresponding components are given the same reference numbers, and redundant description thereof will be omitted. do. In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. In the drawings, the thicknesses of layers and regions are exaggerated for clarity.

Referring to FIG. 1, the auditory examination system 10 according to an exemplary embodiment includes a display unit 100, a sound output unit 200, a detector 300, and a controller 400. In addition, 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 the examinee. In an embodiment, the display 100 may display a virtual reality image to the subject. In this case, the display unit 100 may block a subject from an external reality background to increase the concentration of the subject, and provide a closed-view head mounted display to effectively display a virtual reality image to the subject. Can be.

The image displayed by the display unit 100 to the subject is information recognizable through the subject's perspective, and may be in various forms such as a picture, a photo, a text, a video, a video, and an application execution screen.

In one embodiment, the display unit 100 may display a surrounding image providing an image corresponding to a direction in which the subject's eyes are directed. Specifically, information about the direction of the examinee's eye detected by the detector 300 is transmitted to the controller 400, and the controller 400 controls the display unit 100 to display an image corresponding to the corresponding direction. do. Here, the surrounding image refers to an image which is unfolded in all directions (for example, before, after, left, right, up, and down) around the head mounted display. Of course, the surrounding image is not limited to a spherical virtual reality image, and may be transformed into various types of virtual reality images such as a cylinder and a hemisphere according to a design. As a result, each time a subject wearing the display unit 100 moves his / her head, different images are displayed to the subject, thereby providing a more realistic virtual reality.

However, in order to implement the display unit 100 for the purpose of auditory examination, it is necessary to switch the image displayed to the examinee when it is determined that the examinee has performed a meaningful operation. In the present exemplary embodiment, since the display unit 100 displays the surrounding image, the image displayed to the subject may be switched when the subject performs an operation of rotating the head by an angle within a preset range. At this time, in order to sufficiently secure the range of the angle, it is more preferable to rotate the left and right than to turn the head up and down.

In another embodiment, the display unit 100 may display an image different from the existing image when the examinee performs an operation such as pressing a button or generating a sound in addition to the operation of rotating the head. This is the same as in the above-described embodiment, regardless of whether the subject rotates his head, even if the direction in which the subject's eyes are directed is fixed, the display unit 100 switches the displayed image. The sound generation may be the same as a subject clapping hands or saying a specific word, but is not limited thereto.

While the display unit 100 displays an image to the examinee as described above, the sound output unit 200 outputs a test sound for an auditory test to the examinee. The type of test sound may be appropriately selected in consideration of the age, health condition, etc. of the test subject, and the volume of the test sound may vary depending on the results 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 speech 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, and the examinee 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 together with the actual surroundings. As it is disconnected from the environment, it becomes easier to immerse in the virtual reality implemented through the display unit 100. However, the present invention is not limited thereto, and the sound output unit 200 may have a form in which not only the examinee but also the examiner can hear the test sound together with the 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 and a right sound. The output unit 220 outputs a right test sound for an auditory test of the right ear. The left test sound and the right test sound may of course vary in volume, type, etc., depending on the results of the previous test.

The detector 300 detects a specific operation of the examinee. Specifically, the detection unit 300 detects behavior response behavior such as a head turn of the subject with respect to the test sound direction when the test 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 detector 300 may detect an operation in which the subject rotates his head by an angle within a preset range. This corresponds to an embodiment in which the display unit 100 displays a surround image that provides an image corresponding to a direction in which the subject's gaze is directed. In this case, as described above, it may be preferable that the head of the examinee be rotated left and right rather than being rotated up and down to sufficiently secure the range of the angle.

In the present exemplary embodiment, since the subject rotates his head in response to the test sound output from the sound output unit 200, the direction in which the subject 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 subject rotates his head to the left, and accordingly, the detector 300 determines whether the subject rotates the head to the left by a predetermined range of angles. Will be detected. Similarly, when the right test sound is output from the right sound output unit 220, the examinee rotates his head to the right, and accordingly, the detection unit 300 determines whether the subject rotates the head to the right by a predetermined range of angles. Will be detected.

Therefore, the detector 300 of the present exemplary embodiment may include a gyro sensor for detecting the rotation direction and the rotation angle of the head of the examinee. In order to effectively operate the gyro sensor, the gyro sensor may be installed in the display unit 100 worn on the head of the examinee. As a result, when the subject's head is rotated, the gyro sensor may detect the rotation direction and the rotation angle of the subject's head in real time.

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 into an image corresponding to the rotation direction and the rotation angle.

On the other hand, the operation detected in the present embodiment is almost instinctive operation by simply turning the head in the direction in which the examinee hears the test sound. Therefore, the present embodiment is sufficiently applicable to children of low age without being particularly age-sensitive. .

In another embodiment, the detector 300 may detect a specific motion other than the subject rotating the head. This corresponds to an embodiment in which the display unit 100 displays an image different from the existing image regardless of a change in the direction in which the subject's eyes are directed. That is, even if the subject does not necessarily turn his head, when the subject performs an operation such as pressing a button or generating a sound, the display unit 100 switches the displayed image.

In the present embodiment, the detector 300 may detect an operation of pressing the button. Of course, the present invention is not limited thereto, and the detection unit 300 may detect an operation of touching various touch means. In addition to the above-described operation of the touch, the detection unit 300 may be used by a subject to clap or say a specific word. The sound generating operation can be detected.

As described above, when the detector 300 detects a button press operation of the subject, the image displayed on the display 100 is switched to an image different from the existing image.

On the other hand, the detecting operation in the present embodiment requires the subject's cognitive and application ability more than to rotate the head, which is the detecting operation in the previous embodiment. Therefore, in the case of the present embodiment it may be effective to apply to children older than the subject of the previous embodiment.

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

Specifically, when the detection unit 300 detects the reaction operation when the examinee performs the reaction operation on the test sound output from the sound output unit 200, the controller 400 is displayed on the display unit 100. The image is switched from the first image to the second image. In consideration of the test result obtained through the control process, the control unit 400 again controls the test sound output unit 200, the display unit 100, and the like, thereby following up the test of the subject. Meanwhile, a more specific control method of the controller 400 will be described later with reference to FIGS. 2 and 3.

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

The input unit 90 receives a test condition according to the information of the examinee, and the information of the examinee may mean an age, a medical history, or the like of the examinee. In particular, in the case of the auditory examination system 10 according to an embodiment of the present invention, there is a difference in the easy-to-apply embodiment according to the age of the examinee, the age of the examinee is important to determine the test conditions input to the input unit 90 It can be an argument.

There may be a variety of test conditions input to the input unit 90, but first, a test method according to the age of the examinee may be input. Specifically, when the subject is an infant under 3 years old, the subject detects the motion of turning the head and selects a method of performing the auditory examination of the subject, and the subject is an infant of 3 to 7 years old. In this case, the method may detect an operation of pressing the button and the like to select a method of performing the auditory examination of the subject.

In addition, the input unit 90 may receive an operation mode. Here, the operation mode means manual control or automatic control of the controller 400. Therefore, 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, the control unit 400 performs a control operation manually or automatically.

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

As described above, the control unit 400 repeatedly performs an auditory test on the subject based on the test condition set through the input unit 90. Each auditory test result or the final auditory test result may be stored in the storage unit 500. have. In this case, like the input unit 90, the storage unit 500 may perform wireless communication with the controller 400 as a portable electronic device such as a mobile communication terminal. 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 components, and the input of the test condition and the output of the test result are one. It can also be done in the device.

In detail, the storage unit 500 may store the volume and output direction of the test sound and the response operation information of the test subject to the test sound. For example, when the examinee rotates his head to the left by a predetermined range of angles when the left test sound is output from the left sound output unit 210, the storage unit 500 has information indicating the left test sound and the volume of the left test sound. Information, information indicating that the test subject responds to the left test sound, and the like may be stored.

As another example, when the storage unit 500 stores the final auditory test result, the storage unit 500 stores the final result derived after the test is finished because the reaction of the test subject is no longer detected at a specific sound output sound pressure. Done. In detail, the storage unit 500 may store information on whether the test sound is a left test sound or the right test sound, the minimum volume information of the left test sound / right test sound from which the reaction operation of the test subject is detected, the hearing threshold information of the test subject, and the like. Can be.

In this case, the controller 400 may also perform an operation of analyzing the test results to derive the test results or the final test results each time stored in the storage. That is, the controller 400 may analyze whether the test result is positive, no response or gastric reaction each time, and calculate the hearing threshold information of the test subject based on the minimum volume information from which the test reaction was detected. Herein, the positive reaction means that when the test sound is output from the left sound output unit 210 or the right sound output unit 220, the subject rotates his head to the left or right by an angle in a predetermined range, or presses a button. Means that. On the other hand, the non-response means that the examinee does not rotate the head by an angle of a preset range or press the button to be on even though the test sound is output. In addition, the above reaction means that the subject turns the head or presses the button even when the test sound is not output, the subject turns the head in the direction opposite to the output direction of the test sound, and the output direction of the test sound. Regardless, it means that the subject repeatedly shakes his head.

On the other hand, information on whether the test sound is left / right and the volume of the test sound may be stored in the storage unit 500 through the control unit 400 as illustrated in FIG. 1, but is not limited thereto. May be stored directly in the storage unit 500.

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

First, referring to FIG. 2 and FIG. 1 described above, the examinee 1 wears the display unit 100 in the form of a head mounted display capable of displaying a virtual reality image on the head. In addition, the examinee 1 wears headphones or earphones that function as the sound output unit 200.

On the other hand, prior to starting a full-fledged auditory examination, the input unit 90 includes a test method, an operation mode, a type of image displayed on the display unit 100, and an audio output unit 200 as test conditions according to the age of the examinee 1. The type and volume of the test sound output from the system are input. In the present embodiment, the input unit 90 may input a test condition when the subject 1 is an infant under 3 years old.

Before the test sound is output from the sound output unit 200, the first image IM1 is displayed on the display unit 100. The first image IM1 may include a first object OB1 in which an animation character or the like that is preferred by the examinee 1 who is under 3 years old is preferred. As a result, the examinee 1 is interested in the first object OB1 and fixes his / her eyes in the first image IM1, thereby refraining from moving his head.

As described above, while the gaze of the examinee 1 is directed toward the first image IM1 on the display unit 100, the sound output unit 200 outputs an inspection sound for the auditory examination to the examinee 1. At this time, when the examinee 1 listens to the output test sound, the examinee 1 instinctively turns his head in the direction in which the test sound is output, and thus the display unit 100 recognizes the examinee 1. The image of is switched from the first image IM1 to the second image IM2.

Specifically, when the examinee 1 listens to the test sound while the left test sound is output from the left sound output unit 210, the test subject 1 has a first angle θ1 in the direction in which the left test sound is output. Turn your head by). At this time, the detector 300 detects a reaction operation in which the examinee 1 rotates the head by the first angle θ1 to the left, and transmits the detection information to the controller 400.

Thereafter, the control unit 400 controls the display unit 100 to display a left image IM21 corresponding to the first angle θ1 of the surrounding image. That is, the image displayed on the display unit 100 is switched from the first image IM1 to the left image IM21. The displayed image may be the same as the left image IM21 as long as the first angle θ1 is within a predetermined angle range. The left image IM21 is an image different from the first image IM1 and may include, for example, a second object OB21 different from the first object OB1 of the first image IM1. The second object OB21 may also be an animation character preferred by the age group children of the examinee 1, and like the first object OB1, the gaze of the examinee 1 may be fixed instantaneously.

Thereafter, the control unit 400 analyzes whether the reaction operation information of the examinee 1 received from the detection unit 300 is 'positive reaction', 'no response' or 'stomach reaction'. In this case, when the control unit 400 determines that the reaction operation information is 'positive response', the test result includes information indicating that the test sound is left, information about the volume of the test sound left, information about the test subject's response to the test sound left, and the like. Can be stored in a storage unit. In addition, the controller 400 may adjust the volume of the left test sound in a 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 lower than the volume of the previous output sound when the 'exact response' is detected in the previous test, and if the 'no response' or 'false reaction' is detected in the previous test, The volume is louder than the output sound.

As described above, when the hearing test of the left ear of the examinee 1 ends, an auditory test of the right ear of the examinee 1 may be performed. Like the hearing test of the left ear described above, when the right test sound is output from the right sound output unit 220, the examinee 1 rotates his head by a second angle θ2 in the direction in which the right test sound is output. . In this case, the detector 300 detects a reaction operation in which the examinee 1 rotates the head by the second angle θ2 to the right, and transmits the detection information to the controller 400.

Subsequently, the image displayed on the display unit 100 under the control of the controller 400 is switched from the first image IM1 to the right image IM22. The displayed image may be the same as the right image IM22 as long as the second angle θ2 is within a predetermined angle range. The right image IM22 is an image different from the first image IM1 and may include, for example, a second object OB22 different from the first object OB1 of the first image IM1.

In this case, the second angle θ2 for displaying the right image IM22 may have the same angle range as the first angle θ1 for displaying the left image IM21. However, the present invention is not limited thereto, and the angle range of the second angle θ2 and the angle range of the first angle θ1 may be different according to the behavioral habits or the physical condition of the examinee 1.

In addition, 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 when the objects OB21 and OB22 are the same, the interest of the examinee 1 may be reduced when performing the repetitive inspection, and thus it may be difficult to obtain the effect of sufficient gaze fixation, so that the second object OB22 of the right image IM22 Is different from the second object OB21 of the left image IM21. Of course, as long as there is sufficient effect of eye fixation, both objects OB21 and OB22 may be identical.

On the other hand, for the sake of convenience, the hearing test of the left ear is performed after the hearing test of the left ear, but the hearing test of the right ear is performed first and the hearing test of the left ear is performed later, or the left and right hearing test is arbitrarily performed. It is also possible to choose and perform.

Thereafter, the controller 400 appropriately controls the volume, the number of outputs, the output direction, and the like of the test sound output from the sound output unit 200 based on the information on the presence or absence of the reaction operation of the examinee 1 received from the detector 300. Subsequent hearing tests are repeated. As described above, after repeatedly performing the same or similar tests, the controller 400 analyzes the test results and stores the final result including the hearing threshold of the examinee 1 in the storage 500.

3 is a conceptual diagram schematically illustrating an auditory inspection system according to another exemplary embodiment of the present invention. Hereinafter, with reference to FIG. 2 will be described based on the difference between the embodiment of the auditory inspection method and its modifications, the content overlapping with the previous embodiment and the like will be omitted or abbreviated.

Referring to FIG. 3 and FIG. 1 described above, the examinee 1 wears the display unit 100 in the form of a head mounted display capable of displaying a virtual reality image to the head, and functions as a sound output unit 200. Wear headphones or earphones. In addition, the examinee 1 can pinch the button device capable of pressing the button when listening to the test sound. Of course, the button device does not necessarily need to be located on the body of the examinee 1, and may be located anywhere within the reach of the examinee 1. In addition to the button device, any device may be used as long as it is a device for detecting a reaction operation of the subject 1. For convenience of explanation, the detection unit 300 includes the above-described button device, and will be described in detail with reference to a case in which the button pressing operation of the examinee 1 is detected as a reaction operation to the test sound.

Prior to starting a full-fledged auditory examination, the input unit 90 may input a test condition when the examinee 1 is an infant of 3 to 7 years old.

As shown in (i) of FIG. 3, the first image IM1 is displayed on the display unit 100. This step means a step before the test sound is still output from the sound output unit 200. The first image IM1 may include a first object OB1 in which an animation character or the like that is preferred by the examinee 1 who is 3 years old to 7 years old is preferred. As a result, the examinee 1 may be interested in the first object OB1 and may fix the gaze on the first image IM1 to concentrate on the auditory examination.

Thereafter, as shown in (ii) of FIG. 3, while the gaze of the examinee 1 faces the first image IM1 on the display unit 100, the sound output unit 200 performs an auditory test on the examinee 1. Outputs a test tone for At this time, the examinee 1 presses the button device provided in the detector 300, and accordingly, the image of the display unit 100 viewed by the examinee 1 is from the first image IM1 to the second image IM2. Is switched to.

In this case, 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 have a form in which the facial expression, motion, clothes, etc. of the first object OB1 of the first image IM1 are partially changed. Accordingly, the image displayed on the display unit 100 may be implemented as an image similar to animation, which may be effective to induce interest of infants aged 3 to 7 years. Therefore, the concentration of the hearing test can be further improved for the subjects 1 of the age group. However, the objects included in the first image IM1 and the second image IM2 are not necessarily limited to the same, and as in the previous embodiment illustrated in FIG. 2, the second object OB2 of the second image IM2 is not limited to the same. May be different from the first object OB1 of the first image IM1.

Thereafter, the controller 400 appropriately controls the volume, the number of outputs, the output direction, and the like of the test sound output from the sound output unit 200 based on the information on the presence or absence of the reaction operation of the examinee 1 received from the detector 300. Subsequently, subsequent hearing tests are repeatedly performed. Based on this, a final result regarding the hearing of the examinee 1 is derived and stored in the storage unit 500.
