2. Description of the Related Art In a complex society in recent years, people are sometimes required to cope with various environmental changes. In particular, the current IT (Information Technolo
gy) In the age of change, the ability to recognize changes in the daily living environment, respond to these changes, and respond appropriately is essential to maintaining a healthy social life. It is always required in daily life.

[0003] In addition, an individual retains the ability to recognize, react to, and respond to this daily change in the living environment ("recognition, reaction, response" ability). Information or how this "recognition / reaction / response" ability changes with various experiences and aging, as basic response / discrimination ability of daily life, for example, It is considered necessary for obtaining a driver's license, occupational skills such as customer service, determining the degree of a disease such as dementia (eg, so-called Alzheimer's disease, a senile dementia) and treatment method, and implementing nursing care insurance. I have.

[0004] Furthermore, in the modern society, elements of the living environment, which are expected next to material richness, extend to the pursuit of comfort, which is called personal preference or amenities.
In rehabilitation of rivers, rehabilitation of roads, granting of various subsidies to rural areas, and development of new products, efforts have begun to see how to satisfy the satisfaction of residents and related citizen groups.

[0005] For this reason, it is expected that the judgment of recognition / reaction / response / ability should be improved in accuracy and made to correspond to various personal characteristics (eg, age, gender, occupation, etc.) in detail.

[0006]

However, at the present time, regarding the determination of Alzheimer's disease (senile dementia), there are currently no methods for measuring at a clinical site, such as determination based on the speed of the pupil following light from a flashlight or the like. However, in this measurement method, if the subject is painful or if the symptoms are not considerably advanced, comparison with a healthy person cannot be performed, and the measurement accuracy may be poor. is assumed. In addition, when various types of driver's licenses that are closely related to daily life are granted to a certain individual, it is difficult to quantitatively measure the ability of “recognition, reaction, and response” as a characteristic of a certain individual. there were.

Further, a specific method has been established for quantitatively measuring individual preference, which is strongly influenced by individual subjectivity, so-called “amenity intensity (including negative direction)” for a certain group. Not at the moment, "Currently,
・ ・ ”Is in a bottleneck.

Therefore, the present inventors, using, for example, a personal computer (PC), which has been widely used, can easily and quickly realize this individual recognition, reaction, and response ability with high accuracy. We sought a method to measure quantitatively by using.

[0009] In view of the above, the present invention provides a simple, quick, and highly accurate quantitative analysis of an individual's ability to cope with environmental changes in daily life, such as "recognition, reaction, and response". It is an object of the present invention to provide an identification / reaction measurement method, a computer-readable recording medium recording an identification / reaction measurement program, and an identification / reaction measurement device.

The image database 177 stores a plurality of types of image data. The image database 177 includes, for example, various image data (for example, face, flower, animal, cry, random number table) serving as a material of a test image to be presented to a subject.
Is stored and recorded in accordance with a predetermined classification / type. The image data includes not only human faces, flowers, animals, random number tables and the like, but also desired inspection purposes (for example, obtaining a driver's license, determining the degree of a disease such as Alzheimer's disease, determining a treatment method, nursing care insurance, etc.). , Etc.) is appropriate moving image or still image data corresponding to the degree of necessity. Furthermore, data with sound (for example, animal squeal) may be included. The image data can include a plurality of patterns of data for each type of face, flower, animal, and the like.

FIG. 2 is a flowchart of the identification / reaction measuring apparatus 100 according to the present invention. Note that, for convenience of explanation, the description of the flowchart here is schematic, and a specific description will be given later. As a principle of the identification / reaction measurement method, as described above, the display (output) unit 30
Is divided into a plurality of screens, and on the divided small screens, target screens (including those in which the determination is confusing and / or ambiguous) for similar / identical determination are compared with the reference image, respectively. Presented, and the subject selects from these target images the images that are determined to match or relate to the reference image.

First, the test image creation unit 20 selects test conditions such as the degree of difficulty or the test purpose, the number of screens to be presented, and the number of questions according to the subject and the test purpose, and stores the conditions in the test condition file 171. It is stored (S101).
Next, the test image creation unit 20 checks the inspection condition file 171
Is read out, and based on the data, the frame of the screen on the display (output) unit 30 is laid out (layout) (S103). The test image creating unit 20 further reads the inspection conditions such as the difficulty level in the inspection condition file 171 selected in step S101, and reads the inspection condition correspondence file 1
Based on the correspondence between the inspection conditions and the reference image, the target image, and the like stored in the image data 76, the use range of the image for the question is determined from the image database 177, and the question data file 1 is determined.
72 (S105). Further, the test image creating unit 20 creates a screen by selecting a reference image and a target image displayed corresponding to the reference image from the question data file 172 and incorporating them into the layout determined in step S103. The created screen is presented to the subject by the display (output) unit 30 as a test image (question).

Next, the subject, for example,
Using 0, an answer to the question created in step S107 and presented on the display (output) unit 30 is given (S
109). The measurement (recording) unit 50 determines whether or not the subject's answer is correct (S111). If the answer is correct, a signal indicating the correct answer by visual and / or audible display (for example, “ping-pong” in sound or a blue lamp) Etc.) (S11)
3) If the answer is incorrect, a signal of the incorrect answer (for example, "Boon" or a red lamp in sound) is output (S11).
5). In addition, the measurement (recording) unit 50 determines, for example, the test image (combination of images) created in step S107, the time until the subject answers in step S109, and the correct or incorrect answer in step S111. Various data relating to the “recognition / reaction / response” ability are recorded in the response data file 173 (S117). Next, the measurement (recording) unit 50 determines whether the number of questions according to the inspection conditions such as the difficulty level is sufficient based on the answer data file 173 and the reference data file 174 (S119). As an example, here, the appropriate number of questions is 5 to 3
It can be about 0 times. However, the question will remain until the necessary records are obtained for the test purpose and the subject.
Any number of times can be created.

Next, the determination unit 60 determines in step S117
Response data file 173 by the measurement (recording) unit 50
The answer record of the subject recorded in the above is compared with the data in the reference data file 174 in which the judgment criteria are stored based on the difficulty level of the question and the past experience, and is analyzed quantitatively. Make a determination (S121, details will be described later)
The measurement result is stored in the test result file 175 for each subject, and is output by the display (output) unit 30 in accordance with a desired situation (display on the screen, printing, consideration for performing appropriate treatment, and the like). Hereinafter, the processing of each step of the above-described flowchart will be described in detail.

(Regarding Step S101) The inspection conditions include, for example, difficulty, purpose, number of screens to be presented, number of questions, and the like. Further, the inspection conditions can include the type and classification (male and female, age group) of the image database 177. As the selection of the degree of difficulty according to the subject, for example, in consideration of the degree of Alzheimer's disease or the like, appropriate steps can be set for healthy patients to severely ill patients (for example, about 5 to 10 steps). The greater the number of screens to be presented, the higher the difficulty level and the higher the information processing capability. Also, when the front face is used as the reference screen,
Assuming that the target screen is a face facing sideways or the like, the front face photographed from a direction having a large angle is more difficult. In addition, when a blurred face is set as the target screen, the degree of blur increases as the degree of difficulty increases. Further, when a rotated face is used as the target screen, the difficulty increases as the rotation angle increases. As described above, the table recorded in the desired search condition corresponding to the type and quantity of the question is stored in the inspection condition file 171.

(Regarding Step S103) As the number of presentation screens used for determining the frame of the screen, for example, one reference image is provided at the center of the screen, and N (for example, 8 to 15) ) Can be arranged (the case of arranging eight target screens will be described later). The number of presentation screens can be set in the inspection condition file 171.

(Regarding Step S105) FIG. 7 shows an example of an explanatory diagram of the image database 177. As described above, the database described in the image database 177 includes, for example, Mr. A to Mr. Z by gender and age (age group).
There are databases by person name and shooting angle, in which a huge number of faces up to Mr. are shot in front (angle = 0 °), appropriate angles = α, β, γ,... . In the figure,
The front image of Mr. A is indicated as A ₀ , the image from the angle α degrees as A _α , the image from the angle β degrees as A _β , and the like.

The determination of the reference image and the target image use range according to the difficulty of the subject is performed by using the image database 17.
7 from the plurality of image data included in the test condition file 171 according to the test conditions such as the difficulty level of the subject and the test purpose, refer to the test condition correspondence file 176 and use the appropriate reference screen and target screen. The range can be determined.

FIG. 8 shows an example of an explanatory diagram of the inspection condition correspondence file 176. The inspection condition correspondence file 176 stores the relationship between the reference image and the target image corresponding to the inspection condition. In this example, the types of images are stored in correspondence with the inspection conditions such as the degree of difficulty. However, the present invention is not limited to this, and a plurality of parameters (difficulty, inspection purpose, image type, image database 17
7), the number of presentation screens, etc.)
A target image may be selected. Here, the reference image and the target image at appropriate angles are obtained according to the degree of difficulty stored in the inspection condition file 171. In addition, as for each image, a plurality of types, that is, images of a plurality of angles α, β, and the like may be randomly mixed and selected.

FIG. 9 shows a question data file 172.
FIG. Here, the image _A 0 of the front as a reference _image, B 0, · · ·, _{Y 0,} the image A _beta from the angle beta as the target image, B _beta, · · ·, showing an example where Y _beta is selected.

(Step S107) Next,
The test image creation unit 20 determines the reference screen and the target screen
By applying each to the defined screen frame,
Create a screen (test image: questions) to be presented to the examiner. Ingredient
Specifically, the test image creation unit 20 stores the question data file
172, for example, as the reference screen, the center of the screen
Image C of Mr. C at an angle of 0 ° ₀As the target screen,
Image C of angle C around the reference screen_β8 paintings including
Image (A_β, B_β, ... X_βEtc.) in random or predetermined order
They are appropriately selected and arranged at appropriate positions.

Here, a specific example of the created screen will be described. FIG. 3 is an explanatory diagram illustrating a measurement example using the test image 70. Here, a human face is used as the test image. The human face is a basic movement that needs to be repeatedly determined on a daily basis for a very wide range of age groups, from infants to the elderly, and is essential for maintaining a healthy social life. I can say.

The test image 70 is composed of, for example, a screen frame of 3 rows × 3 rows and a combination of 9 small images, and includes a reference image 71 arranged at the center of the screen and a reference image 71. Images 72 randomly arranged around the object
To 79. The reference image 71 is, for example, the face of Mr. A facing front. The target image 72 is a profile of Mr. B,
The target images 73 and 78 are the profile of Mr. C, and the target image 7
4 and 76 are the side faces of Mr. D, and the target images 75 and 79
Is the profile of Mr. E, and the target image 77 is the profile of Mr. A who is the correct answer to the question. In order to clearly impress the reference image 71 on the subject, for example, the color of the surrounding frame or the background may be changed. As image data, besides human faces, flowers, plants that exist nearby, dogs,
It is possible to use an image according to the purpose of each test, such as a familiar pet such as a cow or a livestock.

As a modified example of the test image 70, the reference image 71 located at the center of the screen is a face facing the front of Mr. A, and eight target images are randomly arranged around the reference image 71. 72 to 79, 8 to A to H
It may be a profile of a person. Alternatively, the reference image 71 may be a profile of Mr. A, and all of the target screens 72 to 79 may be frontal faces. Further, the reference image and the target image may be images corresponding to the whole or a part (for example, eyes, nose, mouth, etc.).

As described above, at the time of processing by the measurement (recording) unit 50 and the determination unit 60, not only a simple comparison of a part of a test image but also an unknown part, that is, an “analog In addition, a part of “recognition reaction / judgment” is included, and several sets of this test image are selected from combinations that are easy to identify to combinations that are difficult to identify according to the desired inspection purpose.
By repeatedly presenting several tens of sets to the subject, highly reliable measurement results can be collected. In many cases, the subject does not directly know Mr. A to H randomly selected from the huge amount of image data stored and recorded in the image database 177. You will make your own analogies and guide your answers.

In addition, considering the photographing angle of the face and the like, more combinations of the reference image and the target image can be created depending on the purpose of the examination, the aging characteristics of the subject, and the like.

Here, still another display example of the test image (question image) will be described. FIG. 4 is an explanatory diagram illustrating a display example using the reference image 80. The reference image 80 is an image that is rotated at an appropriate angle and replaces the reference image 71 included in the test image 70 described above, and is an image that is rotated upside down by about 180 degrees (the forehead is lower, the chin is lower). Above) 81,
An image 82 rotated by about 135 degrees and an image 83 rotated by about 90 degrees are included.

FIG. 5 is an explanatory diagram showing a display example using the reference image 90. The reference image 90 is, for example, an image in which the clarity is changed in place of the reference image 71 included in the above-described test image 70, and the number of pixels per unit length is extremely small, and the identification of the individual is small. It includes a blurred reference image 91 that is difficult and a reference image 92 that is somewhat clearer than the reference image 91. By using the reference image 90 in this manner, how quickly the correct answer can be obtained in the change from the reference image 91 to the reference image 92, that is, in the dynamic process of gradually changing to a normal / clear image. Various "recognition / reaction / response" abilities until discrimination of information obtained from vision, such as analogy, can be clearly measured with high accuracy. In addition, in addition to this, a picture (eg,
Dog), characters that can be analogized to the target image (eg, dog,
(A dog) or a picture (eg, kennel, collar). By preparing in advance an inspection condition correspondence file 176 in which the type (type) of a predetermined image is stored in correspondence with inspection conditions such as difficulty, these various images can be appropriately selected according to inspection conditions such as difficulty. .

(Regarding Step S109) The subject
The above-described test image presented on the display (output) unit 30 (N persons including an angle of 0 ° at the center of the screen as a reference screen, and N persons including an angle β of C around the reference screen as a target screen) ,
The target image (here, Mr. C of the photographing angle β) that is determined to be the same person as the reference image is selected from the surroundings by looking at the arranged images. At this time, if the screen on the display (output) unit 30 is a touch board type display, the target image presented on the screen is directly touched with a finger. Note that, depending on the type of the display (output) unit 30, the image number of the target screen may be input using a keyboard, or the subject may read out the correct image number aloud. Note that the target image may be rotated at an appropriate angle or the clarity may be changed as in the case of the reference images 80 and 90 described above.

FIG. 10 is an explanatory diagram of the answer data file 173. Thus, the answer data file 173
Stores the correctness of each question of the subject, the reaction time, the average, and the like.

(Regarding Step S121) Here, the processing in the judgment section 60 will be described. FIG. 6 is an explanatory diagram of data stored in the reference data file. In this manner, data on the graph 95 indicating the “standard reaction speed” for each degree of failure is stored. This graph 9
5 is, for example, classified into about 10 levels of disability from a healthy person to a patient suffering from severe illness by a conventional physician's judgment, and the “standard response speed” obtained in advance in each category. (Reference Reaction Speed), a horizontal axis indicating each degree of failure, and reaction speed (for example, seconds)
, The curve 96 when the reference image and the target image are both front-facing, the reference (or target) image is front-facing, and the target (or reference) image is oblique (for example, a shooting angle of 45 degrees). , And a curve 98 when the reference (or target) image is in the front direction and the target (or reference) image is in the horizontal direction (for example, a shooting angle of 90 degrees).

The determination unit 60 includes a measurement (recording) unit 50
A reference data file created based on the subject's response records recorded in the response data file 173 based on the difficulty level of the question and the past experience (accumulated highly reliable "standard response speed") Compared with 74, it is quantitatively analyzed, the measurement result is determined, and the measurement result is processed so that it can be output according to a desired situation. Here, the data included in the subject's answer record includes the time required to answer the question and the difficulty of the question. The difficulty of this question is the easiest with the curve 96 and the most difficult with the curve 98.

Here, when the inspection conditions such as the degree of difficulty stored in the inspection condition file 171 correspond to the curve 96, the determination unit 60 determines, for example,
0 indicates the average response speed of the subject, and if it is 5 seconds, the degree of disability is determined to be “3” in the light of the conventional standard value.
5 is stored. Thus, the degree of failure is quantitatively analyzed.

In general, subjects suffering from illness depend on the date of examination, the surrounding environment (whether the family is watching by the side, etc.), the degree of disability, the condition of the disease, etc. Is not assumed. For this reason, the determination result here is such that, for example, the determination result immediately after the end is displayed one step lighter (recovered) in the determination result immediately after the completion of the same determination as the previous inspection. In addition, a psychological therapeutic effect in consideration of the condition of the subject can be expected.

Here, other features of the identification / reaction measurement method and the identification / reaction measurement device according to the present invention will be described. In order to measure the subject's “speed from the eye to the brain to the hand (voice)”, the determination unit 60 displays a set of test images (questions) on the display (output) unit 30 and then uses the keyboard, Appropriate answer input unit 40 such as touch panel and microphone
In addition to measuring the time until an answer is given, classifying and evaluating the ability of the subject by comparing the correct or incorrect answer of the answer, the difficulty of the question, the response speed of other subjects to the same question, etc. be able to.

As described above, the measurement relying on vision is
Although it has a wide range of application, it is possible to create a question including not only an image but also a sound in accordance with an examination purpose, an aging characteristic of a subject, and the like, and perform a measurement relying on hearing. Specifically, for example, cattle, horses, pigs, goats, chickens, dogs, cats, crows, and small birds are randomly arranged with respect to the above nine small images, and the sound of any of the animals (for example, , And the like, from a speaker or the like, so that the subject can hit the animal. In addition, using images that do not include characters such as human faces, flowers, animals, buildings,
By measuring it, it can be applied to people living in any language area.

In addition, the ability relating to “recognition / reaction / response” which affects all situations in daily life is quantitatively measured and measured.
By evaluating, it is possible to quantitatively evaluate individual characteristics that were extremely difficult to evaluate in the past, such as judging the necessity of nursing care, treatment methods for illness, conditions for imparting skills such as driving, and occupational aptitude tests. Can take a different approach.
In this case, as the test image used in the above-described identification / reaction measurement device 100, an image that is close to the face, such as a flower, an animal, or a building, may be used instead of the face.

Further, as test images created by the test image creating section 20, a combination of several tens to several hundreds of small images are arranged vertically and horizontally according to the degree of difficulty of discrimination. By applying an appropriate discrimination / reaction measurement program that can measure and analyze the response of the subject, the ability to evaluate and judge the abilities relating to “recognition / reaction / response” can be extremely easily performed.

In addition, as the data on the subject, the ability for "recognition, reaction, and response to various classes such as age, gender, occupation, etc." is collected, and a database is created based on these data to specify the subject. Can be presented simply and quickly (for example, immediately after the test).

Also, various image data used in the identification / reaction measuring device 100, existing data included in the above-mentioned various hierarchical databases can be bidirectionally transmitted and received using appropriate communication means and a communication network. By doing so, it is possible to judge the ability regarding “recognition / reaction / response” on an individual basis, not only from a remote location in Japan, but also from abroad. Treatment can be performed smoothly.

Further, 1 which is presented on the display (output unit) 30
Since the time corresponding to a set of images is as short as 1 to 10 seconds, for example, even if this is repeated for 20 to 30 sets, a series of measurements is completed in a few minutes. Furthermore, by presenting a combination that is substantially similar (same difficulty level) a plurality of times in the last few minutes, how much the subject's tension (concentration) lasts or how much fatigue the subject feels with the tension To accumulate in the subject at the speed of (specifically, as the concentration decreases, the evaluation and judgment on the ability decreases)
This makes it possible to measure the discriminative reaction characteristics, which were difficult to measure quantitatively.

In the identification / reaction measuring apparatus 100, for example, the same small image is
Since the measurement and evaluation can be performed in a short time and easily without using repeatedly, it is not necessary to consider “accustomed / proficient” to the image presented by the subject. This makes it possible to easily measure the daily condition (for example, fatigue, lack of sleep, etc.) of the subject, the daily variation, the weekly variation of the biorhythm, and the like. In addition, this identification
By repeatedly performing the reaction measurement method, it is expected that the individual will be trained in the ability to recognize, respond, and respond. Specifically, from the subject's eye (or ear) to the brain, from the brain to the hand (keyboard, touch screen)
Alternatively, the response speed to the voice can be increased.

The subjects most like, resonate,
Select one of the screens such as "desired", ... Conversely, the user may select one of the opposite screens, such as "I dislike", "I do not understand", "I want to keep away". These are called individual amenity strengths. These operations are repeated several times (about 10 to 40 times), and the purpose is to examine the strength of the subject's preference (even in the case of negative [dislike]) and the degree of fatigue in the process of recognizing images. , The same / similar image can be repeatedly provided in front of you to quantitatively evaluate the intensity of your preference.

Compared to the above case, although there is no correct answer, selecting one from the group of divided small images, measuring the time required to select a small screen, and selecting the same / similar image Measurement and evaluation methods, such as measuring the strength of the subject's consciousness by repeatedly displaying, and comparing the results of each individual with the results of a group conducted by a large number of people to make a relative evaluation Can do with things.

The present invention is not limited to the object of the natural environment such as “landscape”, but is used to collect consumer feelings for new products such as “acceptance” of newly developed home appliance design. Can also be used as a powerful technique.

The identification / reaction measurement method of the present invention includes a computer-readable recording medium on which the identification / reaction measurement program is recorded, a program product including the identification / reaction measurement program, which can be loaded into the internal memory of the computer, It can be provided by a program product or the like that includes a reaction measurement program and is stored in a computer-usable recording medium. Further, according to the identification / response measurement method of the present invention, the host can remotely determine the ability of “recognition / response / response” based on the input from the PC or the like using a network such as the Internet. Can be analyzed and determined.

According to the present invention, as described above, the ability to respond to environmental changes in daily life, that is, the ability to recognize, respond, and respond to individuals, can be achieved simply, quickly, and with high accuracy. It can be measured quantitatively. Also,
According to the present invention, the ability for "recognition, reaction, and response" that affects every scene of daily life is quantitatively measured,
By performing the evaluation, it is possible to present an evaluation result that is an index for determining the necessity of nursing care for each individual, a method for treating a disease or the like, a condition for imparting skills such as driving, an aptitude test for occupation, and the like. Furthermore, according to the present invention, the subject's "subjectivity" and "liking" (these are referred to as "amenity and comfort" of an individual in recent years) only with the target image without the reference image.
Can be quantitatively measured.

According to the present invention, "physiological and intellectual response speed of human", which could not be measured conventionally or was extremely difficult, can be measured "quantitatively". According to the present invention, since images and simple voices (e.g., animal sounds) are used as needed, internationally common measurements can be performed irrespective of language or custom. According to the present invention, by a simple method, by the same measurement system,
