That is, the light irradiation means and photographing means necessary for field of view measurement, strabismus measurement, extraocular muscle measurement, stereoscopic vision measurement, or Ringcaster measurement performed to measure eye health can be implemented in the form of a sensor module or a camera module.

In addition, the optometry unit 230 may further include sensors capable of irradiating and receiving light to the subject's left and right eyes to measure the eye health condition to obtain refractive index measurement information for the subject's eyes.

Next, the optical unit 240 is located between the optometry unit 230 and the housing 260 to provide the most suitable optical unit 240 corresponding to the type of measurement of the subject's eye health condition.

Therefore, the light blocking part 271 has a shape corresponding to the shape from the glabellar area to the pharynx of the user, not simply supported by the wearer's nose, so that when the head mounted display 200 is worn, the left eye area and the right eye area By physically separating the regions, it is possible to block the light from escaping between them.

In addition, the light blocking portion 271 and the contact light blocking portion 272 are preferably formed of a material having low light reflection and high light absorption.

In addition, since the contact light blocking portion 272 is a portion in contact with the subject's facial skin, it is preferable to be formed of a material having a high buffering power.

The head mounted display 200 optically separates the left eye area and the right eye area in the area for measuring eye health, thereby preventing measurement errors due to optical interference that may occur during measurement.

In more detail, in an embodiment, the processor 175 may measure the eye health state of the subject based on the determined first eye health measurement method.

In detail, in an embodiment, the processor 175 may set the stereoscopic vision measurement content as the first eye health measurement method, and may measure the eye health state of the subject based thereon.

Here, the stereoscopic vision measurement content according to the embodiment may be content for measuring whether an accurate depth (depth) can be recognized using disparity between both eyes.

That is, in an embodiment, the processor 175 may perform eye health measurement based on the stereoscopic vision measurement content.

In addition, the processor 175 may display at least three targets based on the virtual reality image in conjunction with the head mounted display 200 based on the executed stereoscopic vision measurement content.

For example, the processor 175 may display four targets arranged in a line on the virtual reality image.

In addition, in the embodiment, the processor 175 may include a stereoscopic vision measurement interface (a first eye health state measurement interface) capable of selecting a displacement target, which is a target having a depth (depth) different from that of other targets, from among the plurality of displayed targets. can provide

In detail, the processor 175 may display a plurality of targets including one displacement target on the virtual reality image, and may provide a stereoscopic vision measurement interface for selecting a displacement target from among the displayed plurality of targets. .

In this case, in an embodiment, the processor 175 may adjust the position and/or size of the first target to be displayed as the displacement target in order to implement the displacement target having a depth different from that of other targets on the virtual reality image. .

9 to 11 are examples of views for explaining stereoscopic vision measurement content according to an embodiment of the present invention.

9 to 11 , in the embodiment, when the processor 175 generally outputs a virtual reality image in conjunction with the head mounted display 200 , the left eye of the subject wearing the corresponding head mounted display 200 . The virtual reality image may be output based on the first display area 10 corresponding to the area and the second display area 20 corresponding to the right eye area of the subject.

In this case, in the embodiment, the processor 175 is configured to implement the depth (depth) of the first target 1 set as the displacement target among the plurality of targets in the virtual reality image differently from the other targets. 1 A first target (1-1: hereinafter, 1-1 target) output through the first display area 10 and a first target (1-2: hereinafter, 1-1 target) output through the second display area 20 The positions between the first and second tables) can be set differently and output.

Here, the positions between the 1-1 target 1-1 displayed on the first display area 10 and the 1-2 targets 1-2 displayed on the second display area 20 are mutually The difference is that with respect to the 1-1 coordinates (1-1) and the 1-2 coordinates (1-2) that share the same three-dimensional coordinate value (that is, the three-dimensional coordinate value of the first target 1), Display coordinate values for the 1-1 target (1-1) in the first display area 10 and display coordinate values for the 1-2 targets (1-2) in the second display area 20 This could mean that they are different.

In detail, in the embodiment, the processor 175 determines the display position of each of the 1-1 targets 1-1 and 1-2 targets 1 - 2 of the subject wearing the head mounted display 200 . It can be set according to a predetermined distance (ie, depth) to be implemented between the eyeball and the first target 1 .

According to the distance between the human eye (ie, the left eye and the right eye) and the object (in the embodiment, the target) located at a predetermined distance, the position of the object recognized by the person's left eye and the corresponding It can be based on the principle that the position of the object recognized by the person's right eye is recognized differently (ie, parallax occurs), so that the person can recognize the depth (ie, perspective) of the object.

According to the embodiment, the processor 175, considering that the positions of the left and right eyes are variable according to the subject, a first lens that the optical unit 240 of the head mounted display 200 may include in order to standardize this and A second lens may be used to replace the subject's left and right eyes.

In the following description, the description is based on an embodiment in which the left eye and the right eye of the subject are replaced with the first lens and the second lens, respectively, but the present invention is not limited thereto.

In detail, the processor 175 according to the embodiment includes the distance between the first and second lenses of the head mounted display 200 (hereinafter, binocular distance), the first lens and the second lens, and the second lens gazed by the subject. According to the distance between the first targets 1 , the viewing angle at which the subject recognizes the first target 1 , that is, the stereoscopic angle may be determined.

In more detail, the processor 175 is configured to perform a first stereoscopic view for recognizing the first target 1 at a first distance, which is a different distance from other targets, from the first lens, and a first stereoscopic view for recognizing the first target 1 at a first distance from the second lens. A second stereoscopic view for recognizing the first target 1 may be determined.

The stereoscopic perspective according to the distance is preset and stored in the memory, and the processor 175 may determine the stereoscopic perspective according to the distance change for each stereoscopic perspective previously stored in the memory.

Also, in an embodiment, the processor 175 may set the positions of the 1-1 th target 1-1 and the 1-2 th target 1-2 based on the determined stereoscopic view.

Specifically, the processor 175 may derive a first position on the second display area 20 at which the first stereoscopic view determined as above can be realized.

In addition, the processor 175 may set the derived first position to the position of the first and second targets 1-2 that are the first targets 1 displayed on the second display area 20 .

In the same manner, in the embodiment, the processor 175 may derive a second position that can implement the second stereoscopic view determined as above on the first display area 10 , and use the derived second position as the second position. The position of the 1-1 target 1-1 that is the first target 1 displayed on the first display area 10 may be set.

That is, in the embodiment, the processor 175 is configured to position the first and second targets 1-2 to implement the first stereoscopic view corresponding to the left eye on the area recognized by the left eye (the second display area 20 ). may be adjusted, and the position of the 1-1 target 1-1 may be adjusted to realize a second stereoscopic view corresponding to the right eye on the area recognized by the right eye (the first display area 10).

In addition, in the embodiment, the processor 175 is configured to display the first display area 10 and the The first target 1 may be displayed on the second display area 20 .

Thus, in the embodiment, the processor 175 converts the first target 1 displayed by combining the 1-1 target 1-1 and the 1-2 target 1-2, and the 1-1 target Based on the parallax effect based on the position difference between (1-1) and the 1-2 first target (1-2), the displacement target may be displayed at a first distance (depth) that is different from other targets. .

That is, in the embodiment, the processor 175 is configured to implement a displacement target having a depth different from that of other targets (ie, the first target 1 ) on the virtual reality image through the first display area 10 . By setting the positions of the 1-1 target (1-1) of the output virtual reality image and the 1-2 target (1-2) of the virtual reality image output through the second display area 20 differently from each other, can be printed out.

In another aspect, the processor 175 may determine 3D coordinates of targets to be displayed in a 3D virtual space in which a virtual reality image is displayed for stereoscopic measurement.

In this case, the processor 175 may randomly determine one of the plurality of targets as the displacement target so that stereoscopic vision can be confirmed.

For example, when the first to fourth targets are arranged and displayed from the left, the processor 175 may randomly determine one of the first to fourth targets as the displacement target.

In addition, the processor 175 may determine the y-axis coordinate of the displacement target differently from the y-axis coordinates of the other targets in the 3D virtual space. Here, the y-axis means depth and means the direction in which the subject looks at the three-dimensional virtual space, so that the y-axis coordinates are set differently can be understood as meaning that the aforementioned distance has changed.

That is, the remaining targets may be displayed at the same depth in virtual space by matching the y-axis coordinates, and only the displacement targets may be displayed at different depths by changing the y-axis coordinates.

In addition, by differentiating the x-axis coordinates or/and z-axis coordinates of the targets, they can be displayed at different positions at the same depth. In an embodiment, the processor 175 changes only the x-axis coordinates of the targets and the z-axis coordinates match It can be displayed so that the indicators are arranged in a line.

In the embodiment, the processor 175 determines all three-dimensional coordinates of the targets in the virtual space for stereoscopic vision measurement, and then the first display area 10 and the second display area 20 so that the targets are displayed according to the three-dimensional coordinates. It is possible to determine the display coordinates of each target in .

At this time, since the first display region 10 and the second display region 20 according to the embodiment are two-dimensional planes, only the x-axis and z-axis coordinates can be changed. You must use the time difference of the right eye.

In detail, when the three-dimensional coordinates of the displacement indicator are x1, y1, and z1, the processor 175 may calculate stereoscopic views of the left eye and the right eye to be displayed on the three-dimensional coordinates.

As can be seen with reference to FIG. 11 , the stereoscopic view is based on the distance between the first lens corresponding to the left eye and the second lens corresponding to the right eye, the distance between the display area and the lens, and the three-dimensional coordinates of the displacement target. can be decided.

Then, the processor 175 calculates the two-dimensional display coordinates (eg, the x-axis coordinate and the z-axis coordinate) of the first display area 10 for displaying the displacement indicator in the three-dimensional coordinates based on the calculated stereoscopic view. may be determined, and two-dimensional display coordinates (eg, x-axis coordinates and z-axis coordinates) of the second display area 20 may be determined.

That is, by making the x-axis and z-axis coordinates in the first display area 10 and the x-axis and z-axis coordinates in the second display area 20 different from each other, a parallax between the left eye and the right eye occurs, and when the displacement The depth (y-axis coordinate) of the table may be determined.

The processor 175 may obtain the x-axis and z-axis coordinates of the first display area 10 and the second display area 20 so that the remaining targets can be displayed in the three-dimensional coordinates in the same manner. All other marks may have the same depth.

Through this, the processor 175 generates a predetermined parallax when looking at the 1-2 target displayed at the first position and the 1-1 target displayed at the second position from each of the first lens and the second lens. and may implement a predetermined depth (distance) effect corresponding to the generated parallax.

In addition, in the embodiment, the processor 175 implements the position values set for each of the 1-1 target 1-1 and the 1-2 target 1-2, a step-by-step depth (distance) can be adjusted accordingly.

For example, referring further to FIG. 11 , the processor 175 performs a disparity for realizing a displacement target (first target 1) that is as close as 3000 sec at a distance of 4 m to the first display area. The 1-1 target (1-1) of (10) is moved 29 mm to the right from the reference point of the other targets, and the 1-2 target (1-2) of the second display area 20 is moved to the left by 29 mm position can be moved.

In this case, in the embodiment, the processor 175 may also adjust the size of the first target 1 as the depth of the first target 1 to be displayed as the displacement target changes.

In an embodiment, the processor 175 may change the size of the first target 1 in inverse proportion to the depth (depth) of the first target 1 .

Returning again, in the embodiment, the processor 175 may output a plurality of targets including the displacement target implemented as above as a virtual reality image, and a stereoscopic effect for selecting the displacement target from among the plurality of output targets. A measurement interface may be provided.

In addition, the processor 175 may sequentially reduce the difference in depth between the displacement target and the remaining targets according to the subject's selection input and perform stereoscopic measurement step by step.

In detail, the processor 175 is configured to, when the subject selects and fits the first displacement target, sets a second depth difference smaller than the first depth difference between the first displacement target and the remaining targets and a target of one of the targets. It can be determined by the differential displacement table. As described above, the second displacement target may be randomly determined.

The processor 175 may determine the 3D virtual coordinates of the second displacement target and the 3D virtual coordinates of the other targets to have a second depth difference from the other targets.

The processor 175 is configured to display the three-dimensional virtual coordinates for each target based on the three-dimensional virtual coordinates of the targets, the distance between the first lens and the second lens, and the distance between the display area and the lens, in order to display the determined 3D virtual coordinates. Visualization can be calculated.

Next, the processor 175 may calculate two-dimensional display coordinates for displaying targets in the first display area 10 and the second display area 20 according to the calculated stereoscopic view.

In addition, the processor 175 may display the targets on the 2D display coordinates calculated in each of the first display area 10 and the second display area 20, respectively, and display the targets on the predetermined 3D virtual coordinates. there is.

Next, the processor 175 causes the displacement target to be selected according to the subject's input, and if the displacement target is matched, the depth difference is further reduced and then the next stereoscopic measurement is repeated, that is, the depth that the subject can recognize. Stereoscopic vision can be accurately detected.

Also, the processor 175 may acquire a stereoscopic vision measurement result score based on the subject's input to the provided stereoscopic vision measurement interface.

In an embodiment, the processor 175 may calculate a correct answer rate for correctly selecting a displacement target based on the subject's input to the stereoscopic vision measurement interface, and obtain a stereoscopic view measurement result score in proportion to the calculated correct answer rate can do.

In this way, the processor 175 adjusts the position and/or size of the target displayed in the virtual reality image to change the depth of the target, and performs a stereoscopic vision measurement process based on this, such as with polarized glasses. It can be easily implemented by digitizing the principle of stereoscopic vision measurement based on analog equipment.

Meanwhile, in an embodiment, the processor 175 may measure the eye health state of the subject based on the second eye health measurement method determined based on the survey interface.

In detail, in an embodiment, the processor 175 may set the optometry content as the second eye health measurement method, and may measure the eye health state of the subject based thereon.

Here, the optometry content according to the embodiment may be content for measuring visual acuity and focus ability.

More specifically, in an embodiment, the processor 175 may perform an eye health measurement based on the optometry content.

12 is an example of a view for explaining optometry content according to an embodiment of the present invention.

In addition, referring to FIG. 12 , in an embodiment, the processor 175 may display an optometry table based on a virtual reality image in conjunction with the head mounted display 200 based on the executed optometry content.

Here, the visual acuity table according to the embodiment is a table used to measure visual acuity, and may be a table in which various characters or pictures (symbols) enlarged or reduced according to a predetermined standard are printed.

In detail, in an embodiment, the processor 175 may display an eye chart located at a predetermined depth (depth) based on the virtual reality image.

Also in an embodiment, the processor 175 is an optometry interface capable of selecting, based on the displayed optometry table, a target symbol, which is a predetermined symbol that the subject is required to select from among a plurality of symbols in the optometry table. (a second eye health condition measurement interface) may be provided.

In more detail, in an embodiment, the processor 175 may determine a target symbol automatically randomly selected by a measurer or the processor 175 from among at least one or more symbols included in the displayed eye chart.

Also, the processor 175 may notify the subject of the determined target preference.

In an embodiment, the measurer who measures the eye health state may determine one randomly selected one among the signs in the eye chart displayed on the virtual reality image as the target sign.

In this case, the processor 175 may acquire information on the target symbol randomly determined by the measurer as described above.

In an embodiment, the processor 175 may acquire information on the target symbol selected by the measurer based on the input unit 160 .

Also, in an embodiment, the processor 175 may output audio data for the corresponding target preference and provide it to the subject based on the obtained target preference information.

For example, when '3' is determined as the target symbol, the processor 175 may output audio data for the corresponding target symbol providing the voice data of '3' and provide it to the subject.

In another embodiment, the processor 175 may itself automatically select a target symbol randomly from among the symbols in the optometry table.

Also, the processor 175 may output audio data for the automatically selected target symbol as described above and provide it to the subject.

For example, when the target symbol is determined to be '3' by its own process, the processor 175 may output audio data for the corresponding target symbol providing voice data of '3' and provide it to the subject. .

Alternatively, in another embodiment, the processor 175 may display a graphic image for the automatically selected target symbol on a perceptible depth of the subject (eg, based on the naked eye numerical value according to the subject's previous optometry, etc.) , the target symbol may be notified to the subject.

For example, the processor 175, when the target symbol is determined to be '3' by its own process, generates a graphic image (here, a graphic image indicating the number 3) indicating the target symbol to a predetermined value in the virtual reality image. It may be provided to the subject by displaying it on the depth (in the embodiment, the depth perceptible by the subject).

Continuing, in an embodiment, the processor 175 may obtain an optometry result score based on the subject's input to the optometry interface provided as described above.

In detail, in an embodiment, the processor 175 may obtain a response of the subject to the target preference determined as above, based on the optometry interface.

In an embodiment, the processor 175 may generate a symbol having a shape corresponding to the target symbol to which the audio data is provided, at least one or more symbols (eg, letters or symbols) in an optometry table displayed on a predetermined depth of the virtual reality image. An input of a subject selected from among may be obtained based on the optometry interface.

In addition, the processor 175 may obtain a response to the corresponding target preference based on the obtained target's input.

In another embodiment, the processor 175 generates a symbol having a shape corresponding to the target symbol displayed on a predetermined first depth (in the embodiment, a depth clearly recognizable by the subject) in the virtual reality image, the virtual reality image. Obtaining, based on the optometry interface, an input of a subject who selects from at least one or more symbols in the optometry table displayed on a second predetermined depth (in an embodiment, a predetermined depth set for testing optometry) of the real image can do.

In addition, the processor 175 may acquire a response to the corresponding target symbol based on the input of the subject obtained as described above.

Also, in an embodiment, the processor 175 may randomly determine a target preference as described above and repeat a series of processes of obtaining a response of the subject to the determined target preference.

At this time, in the embodiment, the processor 175, based on the user (in the embodiment, the measurer) setting and/or the automated process, the visual acuity table output as a virtual reality image is displayed in a step-by-step depth ( depth) can be changed and displayed.

In an embodiment, when the optometry content is executed, the processor 175 may obtain a response to the target preference based on the optometry table displayed on the first depth in the first step measurement.

Thereafter, when the subject correctly selects a symbol corresponding to the target symbol in the first stage measurement, the processor 175 outputs an optometry table on a second depth that is more distant than the first depth in the second stage measurement can do.

In addition, the processor 175 may perform a process of acquiring a response to the target preference based on the optometry table displayed on the second depth.

Also, the processor 175 may repeat the above process until a predetermined nth (n=1, 2, 3, ...) step.

On the other hand, in the embodiment, when the subject does not select a symbol corresponding to the target symbol in the first step measurement, the processor 175 may output an optometry table on the first depth of field also in the second step measurement.

In addition, the processor 175 may obtain a response to the second preference in the second step that is different from the target preference in the first step based on the optometry table displayed again on the first depth as above.

Also, the processor 175 may repeat the above process until a predetermined nth (n=1, 2, 3, ...) step.

In this way, the processor 175 outputs the optometry table as a virtual reality image and performs step-by-step optometry while adjusting the depth of the output optometry table, so that when using a physical optometry table, there are limitations to bear. conditions (e.g., having an optometry equipment, variability of the distance between the subject and the optometry table, limited number of symbols in the optometry table, size and/or location, etc.) can be overcome, and the subject's visual acuity can be measured.

Also, in an embodiment, the processor 175 may calculate an optometry result score based on the responses obtained by performing the above multiple times.

In an embodiment, the processor 175 may calculate an optometry result score of the subject in proportion to a correct rate at which the target symbol is correctly selected, based on the subject's input based on the optometry interface.

However, in general, in the method of displaying the eye chart through an image and providing it to the subject, when the resolution of the device (in the embodiment, the head mounted display 200) for displaying the eye chart is low, the eye chart is not displayed. Due to the inability to display clearly, a situation may arise in which the result of the optometry is determined under the influence of factors unrelated to the subject's visual acuity.

Thus, in an embodiment of the present invention, the processor 175 may set the minimum size of the displayed eye chart according to the resolution of the head mounted display 200 that outputs the virtual reality image.

In an embodiment, the processor 175 may set the minimum size of the output optometry table in inverse proportion to the resolution of the head mounted display 200 that is linked thereto.

That is, in the embodiment, as the resolution of the head mounted display 200 is higher, the processor 175 may set a smaller minimum size of the optometry table output based on the corresponding head mounted display 200, and vice versa. can do.

In addition, in an embodiment, the processor 175 may adjust the depth of the optometry table in the virtual reality image within a range that does not exceed the set minimum size.

For example, after displaying the optometry table having a predetermined size at the first depth, the processor 175 is configured to display the optometry table at a second depth having a greater depth than the first depth (ie, located at a greater distance). When the optometry table is displayed, the depth of the second depth may be determined within a range in which the optometry table does not become smaller than a minimum size set for the optometry table.

In addition, in the embodiment, the processor 175, in the case of an optometry table displayed in a minimum size, converts the form of symbols (eg, characters and/or pictures (signs), etc.) in the corresponding optometry table into a picture (symbol) format. can be converted and provided.

For example, the processor 175 may change the character symbol in the eye chart displayed in the minimum size into a predetermined pictogram (sign) symbol and provide it.

In this way, the processor 175 displays the symbols in the optometry table only in the form of a picture (sign) that is less affected by the resolution compared to the text, and outputs the corresponding virtual reality image in a situation in which the eye chart of the minimum size is displayed. Influence by the resolution of the head mounted display 200 can be minimized.

13 is an example of displaying eye health measurement results according to an embodiment of the present invention.

Specifically, in an embodiment, the processor 175, based on the subject's input to an eye health measurement interface (in an embodiment, a stereoscopic vision measurement interface and/or an optometry interface, etc.) provided in the eye health state measurement process, It is possible to obtain eye health status information for the subject.

In this case, when there are multiple times of eye health state measurement data according to the subject, the processor 175 may provide result information analyzed more precisely based on the plurality of eye health state information.

For example, the processor 175 performs an analysis based on a plurality of eye health state information obtained by measuring eye health state performed a plurality of times, such as glaucoma, which is difficult to accurately grasp only with a one-time measurement of eye health state. It is possible to more accurately predict a disease (ie, a disease that needs to be identified over a long period of time).

Through this, the processor 175 may further improve the performance of the eye health condition measurement service.

Also, in an embodiment, the processor 175 may output the eye health state information obtained as described above based on the display unit 150 as shown in FIG. 13A .

Also, the processor 175 may output eye health state information for the subject through the display unit 220 in conjunction with the head mounted display 200 as shown in FIG. 13B .

In addition, in an embodiment, the processor 175 may store and manage the acquired eye health state information into a database for each subject.

Through this, the processor 175 may digitize and conveniently manage the result data of the eye health state measurement.

In addition, in an embodiment, the processor 175 may transmit and provide the eye health state measurement result data obtained as above, ie, eye health state information, to the eye care application 611 of the computing device 600 .
