Apparatus and Method for Measuring Personal Memory and Concentration based on Recognition Memory }

The present invention is for measuring a person's memory and concentration, and more particularly, an apparatus and method for measuring memory and concentration based on recognition memory using an image, and a computer for executing such a method It relates to a recording medium on which a program is recorded.

Dementia, one of the geriatric diseases, is increasing with the global increase in the elderly population, and although studies for the treatment of dementia are actively conducted, there is no complete treatment method yet.

According to the prevalence survey of the Ministry of Health and Welfare, the number of dementia patients in Korea was 540,000 in 2012, and it is expected to increase rapidly and reach 840,000 by 2020. The dementia population in Korea is growing the fastest in the world, and its social cost is expected to reach 1.5% of GDP in 2050.

Various drugs can be used as a treatment method for dementia, but these drugs only have the effect of slowing the progression, not the underlying treatment of dementia.

However, in the early stages of dementia, if prescribed and treated, it shows a relatively high effect. Therefore, early prediction and early diagnosis of dementia can play a decisive role in alleviating dementia symptoms.

If symptoms are alleviated through early prediction of dementia, unnecessary social/economic costs can be reduced. Early prediction of dementia is an urgent problem in order to solve the rapid increase in the number of dementia patients and high social costs.

The present invention has been devised to meet the above needs, so that ordinary people can easily and easily test memory and concentration without special equipment within a short time to determine early whether or not dementia is suspected. An object of the present invention is to provide an apparatus for measuring memory and concentration based on recognition memory, a method thereof, and a recording medium in which a program for executing such a method is recorded.

In order to achieve the above object, an apparatus for measuring memory and concentration based on recognition memory according to the present invention includes: an image storage unit for storing an image for examination; a display unit for displaying an image for examination on a screen; an input unit for receiving a user's response; and displaying the image for examination stored in the image storage unit on the display unit, and repeating the process of receiving a user's response as to whether the image for examination has been previously displayed through the input unit during the examination time. It consists of an inspection unit that performs.

A method for measuring memory and concentration based on recognition memory according to the present invention comprises: displaying an image for examination on a screen; and receiving a user's response as to whether the image for examination has been previously displayed may be repeatedly performed during the examination time.

The examination image displayed during the examination time includes a general image displayed only once and a repeated presentation image displayed repeatedly.

In this case, the repeated presentation image is displayed secondarily at a first time interval after the first display, and is displayed tertiarily at a second time interval after the second display.

The repeated presentation image is divided into a plurality of types according to the first time interval, and each type is configured to include a plurality of different repeated presentation images.

The first time interval may be configured to be less than or equal to a preset short-term memory retention time, and the second time interval may be configured to be longer than the short-term memory retention time.

The short-term memory retention time may be 20 seconds or more and 40 seconds or less.

(n은 정수)에 비례하도록 구성될 수 있다.The first time interval corresponding to each type of the repeated presentation image is

It may be configured to be proportional to (n is an integer).

The inspection unit according to the user information, the first time interval, the second time interval, the time to display the image for inspection, the time to wait for the user's response, the inspection time, the number of the repeatedly presented image types, and at least one of the number of repeated presentation images belonging to each type may be set.

In this case, the user information may include one or more of age and educational background.

Memory and concentration measuring apparatus based on recognition memory according to the present invention, a response storage unit for storing the user's response; and an evaluation unit for evaluating memory and concentration according to the user's response stored in the response storage unit.

The evaluation unit may be configured to evaluate memory and concentration by using one or more of a correct answer rate and a response time for each displayed image for examination.

According to the present invention, even ordinary people can easily measure memory and concentration using images for examination.

Since the inspection is performed through a simple method of determining whether a periodically visible inspection image has been previously viewed, the stress on the inspection is low and the inspection can be carried out comfortably.

In addition, it can be easily implemented using various computer devices such as personal computers (PCs), smart phones, tablet computers, and notebook computers.

Because images are used, measurement can be performed regardless of the user's language and education level, and there is no learning effect on the test method itself, and repeated measurement is possible because image sets can be replaced.

Since the test images are presented appropriately distributed so that both short-term and long-term memory can be evaluated, memory and concentration can be accurately measured.

As simple and easy accurate measurement is made, it is possible to receive a prescription at an early stage of dementia, which can play a decisive role in alleviating dementia symptoms and reduce unnecessary social and economic costs.

Referring to FIG. 1 , an apparatus 100 for measuring memory and concentration based on recognition memory according to the present invention includes an image storage unit 110 for storing an image for examination and a display unit 120 for displaying an image for examination on a screen. , an input unit 130 that receives a user's response, and an inspection unit 140 that performs an examination using an image for examination stored in the image storage unit 110 .

In addition, the memory and concentration measuring apparatus 100 may further include a response storage unit 150 for storing the user's response, and an evaluation unit 160 for evaluating the user's memory and concentration according to the user's response.

The memory and concentration measuring apparatus 100 may be configured in various ways. For example, according to the present invention, it may be configured as a dedicated device for measuring a user's memory and concentration, or by installing software in various computer devices such as a personal computer (PC), notebook computer, tablet computer, and smart phone. may be configured. In addition, it may be implemented in the form of providing a memory and concentration measurement service through a wired or wireless Internet network by being implemented on the server side.

The display unit 120 visually displays information required for measuring memory and concentration through a screen, and the input unit 130 receives various information and commands required for measuring memory and concentration from the user.

The input unit 130 may be variously configured such as a touch screen, a mouse, a keyboard, a joystick, a button or a switch, and the user's response regarding whether the image for the examination has been previously displayed through the input unit 130 is input. do.

The inspection unit 140 displays the inspection image stored in the image storage unit 110 through the display unit 120 according to a predetermined time interval (image display cycle), and inputs the user's response through the input unit 130 . receive

Here, the user's response relates to whether the corresponding examination image has been previously displayed.

The process of displaying an image for examination, processing it so that the user can see it, and receiving the user's response is repeatedly executed for a prescribed examination time, thereby performing a memory and concentration test based on recognition memory.

In general, the recognition memory refers to a memory for recognizing whether information a user encounters is already memorized information.

2 is an example of an image display period Tu, which is a time interval during which the inspection unit 140 displays each inspection image on the display unit 120 .

The inspection unit 140 displays the k-th examination image on the screen at a time point t1, removes the k-th examination image from the screen at a time point t2, and waits for a user's response from time t2 to time t3. Here, the image display section is between time points t1 and t2, the response waiting section is between time points t2 and t3, and the image display period Tu is the sum of the image display section and the response waiting section.

Then, when the image display period Tu elapses from the time t1 when the k-th examination image is displayed on the screen, the 'k+1'-th examination image is displayed on the screen, and the process of waiting for a user response is repeated.

2 shows an example in which the response waiting section and the image display section are separated, however, since the user may input a response immediately after viewing the image for examination in the current order, the response waiting section is the time when the k-th examination image is displayed on the screen From t1 until the 'k+1'th inspection image is displayed on the screen, it may be set to an arbitrary section.

Response re-input within the response waiting period may be configured to be possible or may be configured to be impossible.

The image display section and the response waiting section may be configured in various ways as needed. As a specific example, an image display section in which an image for examination is displayed may be configured for 0.1 seconds or more and 1 second or less, and a response waiting section waiting for a user's response may be configured for 5 seconds or less.

The inspection image displayed by the inspection unit 140 on the screen through the display unit 120 may be largely divided into a general image and a repeated presentation image.

Here, the general image is an image for examination that is displayed only once during the examination time, and the repeated presentation image refers to an image for examination that is repeatedly displayed twice or more.

Referring to FIG. 3 , the repeated presentation image is displayed primarily at an arbitrary time point during the examination time, and is displayed secondarily after the first time interval Ps has elapsed. Then, after the second time interval Pl has elapsed, it is displayed as a third time again.

That is, the repeated presentation image is repeatedly displayed with a first time interval Ps, and is displayed once again after the second time interval Pl has elapsed, so that it is displayed a total of three times.

The repeated presentation image is composed of a plurality of types classified according to the first time interval. That is, the repeated presentation images exist from the repeated presentation image group having the first time interval Ps of T1 to the repeated presentation image group having the first time interval Ps of Tm. Here, m is an integer greater than or equal to 2, and 'T1 < T2 <...< Tm'.

In addition, each repeatedly presented image group includes a plurality of different repeatedly presented images.

The number of different repeated presentation images belonging to each type may consist of 5 or more and 15 or less, but is not limited thereto.

In addition, the type of the repeated presentation image may be composed of 3 or more and 10 or less types, but is not limited thereto.

Referring to FIG. 4 , in the entire examination image displayed to the user during the examination time, general images displayed only once, and 'repeated presentation images with a first time interval (Ps) of T1' to 'first time interval Repeated presentation images where (Ps) is Tm are included.

Table 1 below shows a specific example of the repeated presentation image to help the understanding of the description. The repeated presentation image is divided into m image types (groups) with different first time intervals (Ps), and each image group includes An example with 10 different repeated presentation images.

Image type first time interval Primary and secondary display images second time interval tertiary display image
#One T1 Image 1-1 Tl Image 1-1 T1 Image 1-2 Tl Image 1-2 ... ... ... ... T1 Image 1-10 Tl Image 1-10
#2 T2 Image 2-1 Tl Image 2-1 T2 Image 2-2 Tl Image 2-2 ... ... ... ... T2 Image 2-10 Tl Image 2-10 ... ... ... ...
#m Tm image m-1 Tl image m-1 Tm image m-2 Tl image m-2 ... ... ... ... Tm image m-10 Tl image m-10

In the example shown in Table 1, 10 different repeated presentation images are included in image group #1 with a first time interval Ps of T1, and 10 images in image group #2 with a first time interval Ps of T2. Different repeated presentation images of the branch are included, and in this way, 10 different repeated presentation images are also included in image group #m with the first time interval (Ps) of Tm.

In the example shown in Table 1, if all repeated presentation images are used for the examination, 'm × 10' repeated presentation images are displayed three times each during the examination time.

The first time interval corresponding to each type of the repeated presentation image may be variously set according to various factors, such as the efficiency of the test, the accuracy of the measurement of memory and concentration, and the like.

As an example, the first time interval corresponding to each image type may be set to have a linear difference.

That is, assuming that the image display period (Tu) is 2 seconds, the first time interval from image type #1 to #m can be set as 2 seconds, 4 seconds, 6 seconds, ... , '2m' seconds. . Then, when the repeated presentation images are displayed in the first and second stages, the repeated presentation images belonging to type #1 are displayed at an interval of 2 seconds, and the repeated presentation images belonging to the type #2 are displayed at an interval of 4 seconds, and the type Repeated presentation images belonging to #3 are displayed at intervals of 6 seconds.

에 비례하도록 설정할 수 있다. 여기서 n은 정수다.As another example, the first time interval corresponding to each image type is

can be set to be proportional to where n is an integer.

That is, assuming that the image display period (Tu) is 2 seconds, when the repeated presentation images are displayed in the first and second stages, the repeated presentation images belonging to the type #1 are displayed at an interval of 2 seconds, and the repeated presentation images belonging to the type #2 are displayed at an interval of 2 seconds. Repeated presentation images are displayed at intervals of 4 seconds, and repeated presentation images belonging to type #3 are displayed at intervals of 8 seconds.

As a criterion for determining the first time interval Ps and the second time interval Pl, a time commonly known as a short-term memory retention time may be used.

In this case, the first time interval may be configured to be less than or equal to the preset short-term memory retention time, and the second time interval may be configured to be longer than the short-term memory retention time. An example of the second time interval may be about 2 minutes, but is not limited thereto.

Repeatedly displaying the primary and secondary within the short-term memory retention time can be an evaluation factor for the user's short-term memory. In addition, since it can be checked whether the image rehearsed within the short-term memory retention time is remembered even after the short-term memory retention time elapses, displaying it once again in the third time can be an evaluation factor for the user's long-term memory and concentration.

The short-term memory retention time may be variously configured according to various factors or research results for accurate measurement of memory and concentration. As a specific example, it may be configured for about 30 seconds, but is not limited thereto, and the short-term memory retention time may be configured for about 20 seconds or more and 40 seconds or less.

에 비례한다고 가정한다.5 is an example showing a state in which a series of images for examination are displayed, in order to help understanding of the description, the image display period (Tu) is 2 seconds, and the first time interval corresponding to each image type is

is assumed to be proportional to

The examination images 31 and 33 are repeated presentation images. The examination image 31 belongs to an image type having a first time interval of 16 seconds, and the examination image 33 belongs to an image type having a first time interval of 4 seconds.

Image 31 for examination was displayed as the primary at an arbitrary time point, then repeatedly displayed in the fourth order, and again displayed in the third after the second time interval elapsed after the second display.

In order to obtain more information that can be used to measure the user's memory and concentration, a method for displaying the repeatedly presented image may be variously configured.

For example, if the first time interval set for an image type exceeds the short-term memory retention time, repeated presentation images belonging to this image type will omit the tertiary display, and only the primary display and the secondary display may be executed. have.

에 비례한다고 가정할 때, 이미지 종류가 6종류이고, 각 이미지 종류에 설정되는 n 값이 1~6이라면, 이미지 종류 #1 내지 #6에 설정된 제1 시간 간격은 각각 2초, 4초, 8초, 16초, 32초, 64초이다.As a specific example, the image display period (Tu) is 2 seconds, and the first time interval corresponding to each image type is

Assuming that there are 6 types of images and n values set for each image type are 1 to 6, the first time intervals set for image types #1 to #6 are 2 seconds, 4 seconds, and 8, respectively. Seconds, 16 seconds, 32 seconds, 64 seconds.

At this time, if the short-term memory retention time is 30 seconds, the repeated presentation images belonging to image types #1 to #4 may be displayed 3 times up to the 1st, 2nd, and 3rd times, but the repetitions belonging to image types #5 and #6 In the presented image, only the 1st and 2nd order are displayed, and the 3rd mark is omitted.

In this way, the percentage of correct answers to the repeated presentation image displayed secondarily after the short-term memory retention time is reduced, but this information can be a great help in accurate memory evaluation through statistics such as setting evaluation criteria and machine learning.

Meanwhile, since the appropriateness of the user's memory and concentration measurement may be changed according to the user's personal situation, the test unit 140 displays the first time interval, the second time interval, and the test image according to the user information as the subject. It may be configured to set at least one or more of a time to wait, a time to wait for a user's response, an examination time, the number of types of repetitively presented images, and the number of repeatedly presented images belonging to each type.

User information that may affect the examination process may be configured in various ways, and specific examples may include the user's age and educational background.

That is, as physical reactivity may decrease with increasing age, a response waiting time may be increased, and an image display time may be increased. In addition, the examination time may be appropriately adjusted according to convenience or age.

For example, users in their 20s and 30s may display an image for 0.1 seconds and set the response latency to around 2 seconds, but for users in their 60s or older, display an image for 0.2 seconds and set the response latency to 3 It can be set to more than seconds.

The response storage unit 150 stores the user response received through the test unit 140 , and the evaluation unit 160 evaluates the subject's memory and concentration according to the user response stored in the response storage unit 150 .

A method for the evaluation unit 150 to evaluate memory and concentration according to a user's response may be variously configured and is not particularly limited.

For example, the evaluation unit 150 may evaluate memory and concentration by using a correct rate for each displayed test image, a response time required for a response, and the like.

Since the repeated presentation images belonging to the same image group are displayed at the same first time interval, they have properties common to the evaluation of memory and concentration, so the user's memory and concentration can be improved by using the correct answer rate and response time for each image group. can be evaluated

Also, the evaluation unit 150 may be configured to evaluate memory and concentration using machine learning.

After evaluating the memory and concentration of the user, the evaluation unit 150 may provide the current location of the user in a group having similar conditions such as the age and academic background of the user.

As a specific example, the evaluation unit 150 quantifies the short-term memory of the user based on the correct answer rate and response time for the repeated presentation images displayed in the first and second order, and based on the correct answer rate and the response time for the repeated presentation image displayed in the third order can quantify the user's long-term memory, and display the user's location in the distribution by age group as a percentage index, etc.

Then, the user can know the level of his or her memory and concentration in comparison with other users whose age and academic background are similar to the user.

6 is an embodiment of a method for measuring memory and concentration based on recognition memory according to the present invention, the process of displaying an image for examination on the screen, and the user's response regarding whether the image for examination has been previously displayed The receiving process is repeated during the inspection time.

Specifically, when the measurement of memory and concentration is started, an image for examination of the current sequence is displayed on the screen (S210, S211).

The image display section in which the examination image displayed through step S211 maintains the displayed state on the screen may be configured in various ways. For example, the image display section in which the image for examination is displayed may be configured for 0.1 second or more and 1 second or less.

Then, during the response waiting period, the user's response as to whether the corresponding examination image has been previously displayed is input (S212, S213).

The response waiting period may be configured in various ways. For example, the response waiting period may be configured to start after the display of the image for examination is finished, or may be configured to start immediately after the image for examination is displayed.

The user may input a response corresponding to 'yes' if the image for examination of the current order displayed through step S211 has been previously displayed, and otherwise may input a response corresponding to 'no'. If a user response is not received during the response waiting period, it may be processed as input of 'no'.

When the response waiting period ends, the process proceeds to step S211 again depending on whether the examination time remains, and the image for the next examination is displayed on the screen or the examination is terminated (S214, S215).

If the time point at which the response waiting period ends and the time point at which the next examination image is displayed do not match, after waiting until the time point at which the next examination image is displayed, step S211 may be performed.

The image display section and the response waiting section may be configured in various ways as needed. As a specific example, an image display section in which an image for examination is displayed may be configured for 0.1 seconds or more and 1 second or less, and a response waiting section waiting for a user's response may be configured for 5 seconds or less.

The image for examination displayed on the screen in step S211 may be largely divided into a general image and a repeated presentation image. Here, the general image is an image for examination that is displayed only once during the examination time, and the repeated presentation image refers to an image for examination that is repeatedly displayed twice or more.

As described with reference to FIG. 3 , the repeated presentation image is displayed primarily at an arbitrary time during the examination time, and is displayed secondarily after the first time interval Ps has elapsed. Then, after the second time interval Pl has elapsed, it is displayed as a third time again.

The repeated presentation image is composed of a plurality of types classified according to the first time interval. That is, the repeated presentation images exist from the repeated presentation image group having the first time interval Ps of T1 to the repeated presentation image group having the first time interval Ps of Tm. Here, m is an integer greater than or equal to 2, and 'T1 < T2 <...< Tm'.

In addition, each repeatedly presented image group includes a plurality of different repeatedly presented images.

The number of different repeated presentation images belonging to each type may consist of 5 or more and 15 or less, but is not limited thereto.

In addition, the type of the repeated presentation image may be composed of 3 or more and 10 or less types, but is not limited thereto.

The first time interval corresponding to each type of the repeated presentation image may be variously set according to various factors, such as the efficiency of the test, the accuracy of the measurement of memory and concentration, and the like.

에 비례하도록 설정할 수 있다. 여기서 n은 정수이다.As an example, the first time interval corresponding to each image type may be set to have a linear difference. As another example, the first time interval corresponding to each image type is

can be set to be proportional to where n is an integer.

As a criterion for determining the first time interval Ps and the second time interval Pl, a time commonly known as a short-term memory retention time may be used. In this case, the first time interval may be configured to be shorter than the short-term memory retention time, and the second time interval may be configured to be longer than the short-term memory retention time.

That is, repeating the primary and secondary display within the short-term memory retention time can be an evaluation factor for the user's short-term memory. In addition, since it can be checked whether the image rehearsed within the short-term memory retention time is remembered even after the short-term memory retention time elapses, displaying it once again in the third time can be an evaluation factor for the user's long-term memory and concentration.

The short-term memory retention time may be variously configured according to various factors or research results for accurate measurement of memory and concentration. As a specific example, it may be configured for about 30 seconds, but is not limited thereto, and the short-term memory retention time may be configured for about 20 seconds or more and 40 seconds or less.

In order to obtain more information that can be used to measure the user's memory and concentration, a method for displaying the repeatedly presented image may be variously configured.

For example, if the first time interval set for an image type exceeds the short-term memory retention time, repeated presentation images belonging to this image type will omit the tertiary display, and only the primary display and the secondary display may be executed. have.

Then, the correct answer rate for the repeated presentation image displayed secondarily after the short-term memory retention time decreases, but this information can be a great help in accurate memory evaluation through statistics such as setting evaluation criteria and machine learning.

Since the appropriateness of the user's memory and concentration measurement can be changed according to the user's personal situation, depending on the user information, the first time interval, the second time interval, the time to display the image for examination, the waiting time for the user's response It may be configured to set at least one of a time, an examination time, the number of repeated presentation image types, and the number of repeated presentation images belonging to each type.

Here, the user information that may affect the examination process may be configured in various ways, and specific examples may include the user's age and educational background.

In describing the method for measuring memory and concentration based on recognition memory according to the present invention, portions overlapping with the description of the apparatus 100 for measuring memory and concentration shown in FIG. 1 are briefly described or omitted.

However, the display of the examination image, receiving a response from the user as to whether the examination image has been previously displayed, the composition of the image display period, the composition of the normal image and the repeated presentation image, the first time interval and the second time interval, Each of the contents described for the concentration measuring apparatus 100, such as the type of the repeated presentation image and the short-term memory retention time, may be applied as long as it does not go against its properties.

The method for measuring memory and concentration based on recognition memory according to the present invention may be implemented as a computer-readable code in a computer-readable recording medium.
