In this embodiment, the electronic document of the student roster or the employee roster may be provided in an excel, csv, or word format, and both the vision detecting device 110 may recognize and utilize the electronic document to generate the list of the detected objects.

In the embodiment, the executing subject is the vision testing apparatus 110, and the vision testing apparatus 110 can communicate with the answering machine 120. The answering machine 120 is provided with a device identifier, the device identifier represents the unique identity of the answering machine 120, the device identifier can be a number, and the number can be constructed by at least one of numbers, letters, symbols and figures.

In this embodiment, the answering machine 120 can generate the vision test question (the first vision test question) and determine the vision result, but the present invention is not limited thereto, and in other embodiments, the vision test question and the vision result may be generated by the processor 112 and then sent to the answering machine 12 via the collector 113. The first vision detection problem includes information on the location of a character on the chart 111. If the character of the common visual acuity chart is E, the first visual acuity test question is to ask the opening direction of the character E of the tested object at a certain position on the visual acuity chart. The answering machine 120 is provided with a display screen, the display screen can display a first vision detection question sent by the vision detection device 110, a tested object can answer the vision detection question based on a key on the answering machine 120, so that the answering machine 120 obtains vision answer information, specifically, the answering machine 120 is provided with four direction keys which are respectively up, down, left and right, the up, down, left and right direction keys respectively represent the up, down, left and right of a character opening direction, when the tested object presses an 'up' key, the vision answer information is that the character opening is upward; the answering machine 120 is further provided with four keys a, B, C and D, wherein the four keys a, B, C and D represent the upper, lower, left and right sides of the opening direction of the character respectively, and if the tested object presses the key a, the eyesight answer information is that the opening direction of the character is upward. The answering machine 120 is also provided with a confirm and cancel key, the object to be tested can answer the identity confirmation questions based on the confirm key, and when the object to be tested presses the confirm key, the identity information of the object to be tested, which is confirmed by the holder of the answering machine 120, is matched with the object to be tested; when the tested object presses the cancel button, it indicates that the holder of the answering machine 120 perceives that the identity information of the holder does not match the tested object, or there is a difference in information, such as a problem of correct name but wrong academic number. When the holder of the answering machine 120 finds that the own identity information does not match the subject to be tested, the holder should return the answering machine 120 to the worker or the person in charge so that the answering machine 120 can be redistributed to the correct hand of the subject to be tested.

When the answering machine 120 obtains the vision result, the vision result can be fed back to the vision detecting device 110. After the vision testing apparatus 110 receives the vision result fed back by the answering machine 120, the device identifier of the answering machine 120 is determined, and then the vision result is associated with the device identifier, whereas the vision result is actually associated with the tested object because the device identifier is associated with the tested object, that is, the vision result is recorded under the tested object.

In this embodiment, the visual acuity chart is obtained by improving a standard visual acuity chart, and includes a character area located in the middle and an indication area located on the periphery of the character area, where information displayed in the indication area includes line sequence information corresponding to the position of a certain character. The efficiency and the accuracy rate of understanding the vision detection problem of the tested object can be improved through the visual chart. It should be noted that the font size of the line sequence information is generally set to be larger, and the font sizes of different line sequence information are basically consistent and do not change with the change of the character size in the character area, so that the tested object can quickly and accurately find the character specified in the vision detection problem. For example, the font size of the line sequence information is selected so that a person with an eye level of five-point notation 4.0 or five-point notation 4.2 can still accurately identify it at the 5-meter line. The line sequence information can be a number, and the number can be constructed by at least one of numbers, letters, symbols and figures; if the row sequence information is represented by a number, the row sequence information may be arranged on the visual chart from top to bottom in sequence, or may be arranged on the visual chart from top to bottom in a disordered sequence, such as "row 3, row 1, row 6, and row 4".

In this embodiment, the eye chart further includes the light-passing board and locates the LED lamp of light-passing board one side, and character district and indicating area locate the one side that deviates from the LED lamp of light-passing board. The backlight function of the visual chart is realized through the light-transmitting plate and the LED lamp, so that the visual detection in a dark environment is facilitated, and the use flexibility of the visual detection system is improved.

In the invention, one visual chart or a plurality of visual charts can be arranged to carry out vision detection on a plurality of tested objects; when the visual chart is one, a plurality of tested objects needing visual detection can be informed to enter visual detection positions corresponding to the visual chart, so that the visual acuity of the plurality of tested objects can be tested through one visual chart; when the eye chart is a plurality of, each eye chart corresponds and sets up one or more eyesight test position, and each eyesight test position can hold a measurand and carry out eyesight test. It can be understood that the vision testing apparatus can simultaneously send corresponding vision problems to a plurality of answering machines so as to test the vision of a plurality of tested objects at one time. The vision detection device can greatly shorten the total duration of vision detection by simultaneously carrying out vision detection on a plurality of detected objects, reduce the queuing time of the detected objects, improve the detection efficiency of the vision detection device and facilitate the realization of large-scale vision detection. In addition, when a plurality of visual charts are used for performing visual inspection on a plurality of tested objects, the row sequence information of two adjacent visual charts can adopt different numbering types, or adopt digital numbering but different numerical arrangement sequences, for example, the row sequence information of the first visual chart from top to bottom is the 1 st row, the 2 nd row, the 3 rd row and the 4 th row, and the row sequence information of the second visual chart from top to bottom is the 4 th row, the 3 rd row, the 2 nd row and the 1 st row. The arrangement is favorable for avoiding the problem that the tested objects participating in vision test simultaneously assist cheating mutually.

Alternatively, the vision test question (the first vision test question) is displayed in text form on the display screen of the answering machine, and the text contents of the vision test questions displayed by different answering machines have information difference. It is understood that a standard eye chart typically has 69 characters, and the total number of position information corresponding to the characters is at least 69, and considering that a row with multiple characters can be counted from the left or right, the total number of position information corresponding to the characters is at least more than 120. When the answering machine generates the vision detection question containing the character position information by a random algorithm, the text contents of different answering machines in the vision detection stage basically have information difference, and particularly, the probability that the text contents on the answering machines of adjacent tested objects are completely consistent is basically zero. It can be understood that if the first one of the two adjacent answering machines displays the "5 th character starting from the left on the 3 rd line", and the second one displays the "1 st character starting from the right on the 3 rd line", such text content difference can effectively avoid the problem of cheating assistance between the tested objects participating in the vision test at the same time.

When the vision test is carried out, the height of the character line corresponding to the five-point recording method 5.0 of the visual chart needs to be ensured to be aligned with the height of the eyes of the tested object when the tested object stands, and the vision result of the tested object only accords with the real vision of the tested object. Therefore, when adopting a plurality of visual acuity test charts to carry out visual acuity test to a plurality of measurands, can set up a plurality of visual acuity test charts of co-altitude not, each visual acuity test chart corresponds a visual acuity test position, and visual acuity test device need arrange measurand to with this measurand height assorted visual acuity test chart. Particularly, as the students in the school are in the physical development stage, the heights of all the students are different, and the vision detection devices can be sorted and then grouped according to the heights of the students so as to generate a more scientific and reasonable list of the tested objects. For example, 50 students in a certain class are arranged according to the height from small to large and then are divided into 5 groups, the height of the first visual chart corresponding to the 1 st group is the lowest, and the height of the fifth visual chart corresponding to the 5 th group is the highest, so that the visual results obtained by testing all the tested objects are close to the real visual level as much as possible.

Referring to fig. 3, in a second embodiment of the present invention, based on the first embodiment, before the step of generating the first vision inspection question by the answering machine when the identity answer information is a positive match, the inspection program further includes:

s90, when the identity answer information is determined to be matched, the answering machine generates a questionnaire survey question;

step S100, the answering machine acquires and sends the survey answer information of the questionnaire survey questions to the processor, wherein the tested object replies to the questionnaire survey questions through the answering machine so that the answering machine obtains the survey answer information;

in step S110, the processor associates the survey answer information with the object to be tested.

In this embodiment, by performing questionnaire survey while performing visual acuity test, there is no need to specifically organize a questionnaire survey after the fact, which saves time and labor costs. And the closer the completion time of vision detection and the completion time of questionnaire survey aiming at the recent personal condition, the higher the correlation degree between the vision result of the tested object and the recent personal condition, and the more scientific and reasonable the correlation between the vision result and the recent personal condition can be analyzed subsequently. Secondly, when the tested objects in the sequence are subjected to vision detection, the tested objects in the sequence can participate in questionnaire survey within the time of waiting in a queue; when the sequenced tested objects finish vision detection, the sequenced tested objects can go to a vision detection position to participate in vision detection after the questionnaire survey is finished, so that the efficiency of the whole detection process can be improved. Furthermore, according to the arrangement, the tested object can directly leave the test field after completing the vision test without being retained on the test field to complete the questionnaire survey, for example, the tested object can be selected to return to a classroom or an office to avoid seriously influencing the study or work progress, which is also beneficial to the management of the on-site order by on-site workers or teachers and avoids the problem of scene confusion caused by frequent walking of the people. In this embodiment, the questionnaire questions are pre-stored in the answering machine and then displayed one by one for the tested object to answer, and finally, all the obtained survey answer information is packaged and sent to the processor together, so as to reduce the communication frequency between the answering machine and the processor. However, the present design is not limited thereto, in other embodiments, the questionnaire questions may be calculated and generated by the processor and then sent to the answerer via the collector, and each questionnaire question may be set in association, for example, if the answer of the first question is 3, the first question may jump to the third question, instead of sequentially displaying each question in sequence.

Optionally, the questionnaire subjects include personal information queries of the age, and/or family eye disease history, and/or residential area, and/or eye usage habits, and/or work and rest habits, and/or eating habits, and/or exercise habits of the student or employee.

Referring to fig. 4, in a third embodiment of the present invention, based on the second embodiment, the step of associating, by the processor, the device identifier of the answer device with the measured object in the measured object list includes:

step S21, dividing the tested objects into a plurality of batches to be tested by taking a class or a department as a unit, wherein the batches to be tested comprise a plurality of tested objects;

step S22, when one of the batches to be tested is in the detection stage, each object to be tested of the batch to be tested is distributed with a question answering device;

and S23, associating the device identification of the answering machine with the tested object in a one-to-one manner according to a preset sorting mode.

In this embodiment, every object that is surveyed all distributes an answer ware, is favorable to avoiding the problem that the vision detection position is idle to appear, and then saves the time of whole vision detection work. Specifically, taking students in 1 class in three years in a certain school as an example to perform vision test on the same batch to be tested, before performing vision test on 1 class in three years, rosters of the students in the class are firstly led into a memory. The information of the student roster comprises a class, a school number, a name, a height, a weight and the like, fifty students are assumed to be in the class, ten visual charts and ten vision test positions are provided, the processor conducts sequencing according to the school numbers of the students, then the vision test device associates the equipment identifications of 50 answering machines with 50 students one by one, and when ten students conduct vision test, the rest 40 students waiting in line can finish questionnaire investigation in the period of time. When the vision detection position is idle, other students can go to the idle vision detection position quickly to perform vision detection, so that the problem that the vision detection position is idle due to the fact that other students continuously complete questionnaire survey is avoided, the vision detection position can be continuously used, and the time of the whole vision detection work is saved. Particularly, when the time required for vision testing is significantly shorter than the time required for questionnaire survey, and each tested object is provided with a question answering device, the speed of completing questionnaire survey by some people is abnormally high, the people can go to the vision detection position first, and buffer time is provided for other people who finish questionnaire survey at a slower speed, so that the vision detection position can be used continuously.

Referring to fig. 5, in a fourth embodiment of the present invention, based on the third embodiment, the vision testing apparatus further includes a speaker communicatively connected to the processor, and after the step of the processor associating the vision result with the object to be tested, the testing program further includes:

step S120, the processor records the timestamp information of the received survey answering information, sorts the equipment identification of the answering machine and the associated tested object according to the timestamp information and generates a detection sorting table;

step S130, the processor detects whether the vision detection position corresponding to the visual chart is idle;

step S140, when the vision detection position is in an idle state, the processor sends test preparation prompt information to the loudspeaker and the answering machine, wherein the test preparation prompt information comprises identity information of a tested object which is positioned at the forefront position of the detection sequencing list in the tested objects waiting for the vision detection;

step S150, the loudspeaker receives and broadcasts the prompt message of test preparation;

step S160, the answering machine obtains the confirmation information of test preparation, wherein, the holder of the answering machine autonomously confirms whether the answering machine is ready to participate in the eyesight test, and replies through the answering machine so that the answering machine obtains the confirmation information of test preparation;

when the test preparation confirmation information is determination preparation, the answerer generates a first vision examination question, that is, performs step S50.

In this embodiment, the detection sequencing of all the detected objects is automatically completed through the processor, and the loudspeaker is used for broadcasting and calling the number, so that the process does not need manual participation, and the labor cost of vision detection is saved. Specifically, taking students in 1 class in three years in a certain school as the same batch to be tested for vision test as an example, before the vision test is performed in 1 class in three years, the roster of the students in the class is firstly imported into the memory. The information of the student roster comprises a class, a school number, a name, a height, a weight and the like, and if the class has fifty students and the visual acuity test chart and the visual acuity test positions have ten, the visual acuity test device sorts according to the school number of the student, and then the processor associates the device identifications of the 50 answering machines with the 50 students one by one. All students participate in the questionnaire survey firstly, and it can be understood that even if the questionnaire survey questions are the same, the response speeds of different people are different, so that the time for all students to finish and submit the survey answer information is different, the processor can sort the fifty students according to the timestamp information of the received survey answer information, namely, the student who finishes the questionnaire survey is preferentially arranged to go to the vision detection position for vision detection. The student who finishes the questionnaire survey at first is arranged as first and carries out eyesight test, and the speaker finishes the suggestion of calling out the number to first student through reporting test preparation suggestion information to make this student go to appointed eyesight test position fast, and this student just can reply through the answer machine if consciously ready, so that the answer machine obtains test preparation affirmation information. The answering machine then begins to generate a first vision examination question, and the first student can begin vision examination. The second student who completes the questionnaire survey is arranged as the second to carry out vision detection, and can call the number to the appointed vision detection position according to the broadcast of speaker, and this student also answers through the answer ware and confirms that it is ready to begin to carry out vision detection, and so on, until ten vision detection positions are all used. The student of the eleventh position of sequencing this moment needs patience to wait for, if one in the first ten students accomplished visual acuity detection, then this visual acuity detection position can be idle and come out, this moment eleventh student just can call the number according to the report of speaker and go to appointed visual acuity detection position, analogize with this, every time there is visual acuity detection position idle back of coming out, other students who accomplish the questionnaire survey just can call the number according to the report of speaker and go to this idle visual acuity detection position fast, and then can make visual acuity detection position use coherently, and save the time of whole visual acuity detection work. Moreover, the processor automatically finishes the detection sequencing of all students and utilizes the loudspeaker to broadcast and call the number, and the process does not need manual participation, thereby saving the labor cost of vision detection. In addition, the vision inspection system automatically and orderly manages personnel for the tested objects on site, and can well maintain the site order management.

Optionally, the processor detects whether the vision detection position corresponding to the eye chart is idle, and may detect and determine according to whether the tested object on the vision detection position submits a vision result, that is, when the tested object detects vision results of both eyes and sends the vision results to the processor via the answering machine, the processor determines that the tested object has completed all vision detections and makes the vision detection position idle. However, the present design is not limited thereto, and in other embodiments, an infrared sensor disposed at the vision detecting position and in communication with the processor may be used, and the infrared sensor may sense whether there is a person at the vision detecting position, and send a sensing signal to the processor to enable the processor to detect and determine whether the vision detecting position is free.

In a fifth embodiment of the present invention, based on the first or second embodiment, the step of associating the device identifier of the answer device with the measured object in the measured object list includes:

step S21', the tested objects are divided into a plurality of to-be-tested batches by taking a class or a department as a unit, each to-be-tested batch comprises a plurality of groups, and each group comprises a plurality of tested objects;

step S22', when one of the batches to be tested is in the testing stage, at least two answering machines are distributed to each group of the batches to be tested for circulating among a plurality of tested objects in the group;

in step S23', the device identifiers of the answering machines are associated with the tested objects one to many in a preset sorting manner.

In the embodiment, in the case that the time required for the vision test is close to the time required for the questionnaire survey, the answering machines and the tested object are associated in a one-to-many manner, so that the input quantity of the answering machines can be saved, and the management cost of the answering machines and the product cost of the vision detection system can be further reduced. Specifically, taking the example that the students in 1 class in three years in a school perform vision testing, before performing vision testing in 1 class in three years, the roster of students in the class is imported into the memory. The information of student's roster includes class, school number, name, height, weight etc. and supposes that this class has fifty students and visual acuity test position has five, and the treater carries out the sequencing according to student's height and divides into groups again, equally divides into 5 groups this fifty students, and 5 groups of students can carry out the visual acuity test on corresponding 5 visual acuity test positions simultaneously. The teacher arranges students into 5 groups in advance according to the list of the tested objects, and the students are arranged into 5 teams in sequence. The processor then associates the device identifications of the 10 responders to 50 students in a one-to-five relationship, each group being assigned two responders, the device identifications of the two responders being arranged in spaced relationship to the students in the group, i.e., the first responder of the group being associated with the students ranked as 1 st, 3 rd, 5 th, 7 th, 9 th, and the second being associated with the students ranked as 2 nd, 4 th, 6 th, 8 th, 10 th. When the students in the first order perform vision test, the students in the second order can participate in the questionnaire survey by using the time, and because the time required by the vision test is close to the time required by the questionnaire survey, the students in the second order complete the questionnaire survey when the students in the first order complete the vision test. The first student of sequencing this moment can give the answer ware in hand to this group the first group member behind the student who finishes the questionnaire survey, just so can make two answer wares circulate between the different group members of same group in an orderly manner to can guarantee whole eyesight detection work's efficiency, save the input quantity of answer ware simultaneously again.

And the vision detection can be periodically repeated after the decision is executed to obtain data feedback, the development situation of vision improvement caused by the improvement decision is continuously followed, and data support can be provided for further guidelines or improvement decisions.

In a seventh embodiment of the present invention, based on the sixth embodiment, after the step of counting and analyzing the question answering information and the vision result, and generating the analysis report, the detection program further includes: s180, pushing eye protection suggestion information to the tested object and/or the mobile intelligent terminal of the guardian of the tested object according to the analysis report, the survey answer information of the tested object and the vision result; wherein the eye protection advice information comprises information of eye use habit adjustment advice, work habit adjustment advice, eating habit adjustment advice and/or exercise habit adjustment advice.

In this embodiment, eye protection advice information is actively pushed to the measured object and/or the mobile intelligent terminal of the guardian of the measured object, which is beneficial to implementing eye protection measures for improving the vision of the measured object or preventing the vision from continuously deteriorating as soon as possible, and social benefits and economic benefits brought by the whole vision detection work can be improved by combining the eye protection measures of individuals with eye protection improvement decisions of governments or enterprises and public institutions. In addition, some commercial advertisements can be pushed in a targeted manner to meet eye protection requirements of users, and user experience is further improved.

Referring to fig. 7, in an eighth embodiment of the present invention, based on any one of the first to seventh embodiments, the step of determining the vision result of the examinee according to the vision answer information and sending the vision result to the processor includes:

step S71, determining vision answers corresponding to the tested object according to the vision answer information;

step S72, obtaining correct answers corresponding to the first vision detection questions, and comparing the vision answers with the correct answers to obtain answer results;

step S73, determining the type of the answer result;

step S74, when the answer result is a wrong result, the answering machine generates a second vision detection question according to the first vision detection question, and the step of executing the answering machine to obtain vision answer information is returned; the size of the character corresponding to the second vision detection problem is larger than or equal to the size of the character corresponding to the first vision detection problem;

after the answer is obtained by the answer device, determining the type of the answer, if the answer is a wrong answer, determining that the vision of the tested object is less than or equal to the vision corresponding to the characters in the current vision detection question (the tested object may have misjudgment, and therefore, the vision of the tested object can be determined to be equal to the vision corresponding to the characters in the current vision detection question), so that a second vision detection question can be generated according to the first vision detection question, namely, the dimension of the characters in the second vision detection question is set to be larger than the dimension of the characters in the first vision detection question, and the vision of the tested object is further determined; for example, the first vision testing question is a second character in the fifth row of the visual chart, if the direction of the character returned by the tested object is wrong, the character in the generated second vision testing question may be the opening direction of the third character in the fifth row to further judge whether the tested object is misjudged, or the character in the generated second vision testing question is the opening direction of the second character in the fourth row of the visual chart (the higher the number of rows of the character is in the position of the visual chart, the larger the size of the character) to judge the vision of the tested object again. After the second vision test question is generated, the process returns to step S60, step S71, step S72, and step S73 for a new round of vision test.

Step S75, when the answer result is the correct result, updating the continuous times of correct answer, wherein the current answer result is the last correct result in the continuous times;

step S76, when the continuous times are less than the target times, generating a third vision detection question according to the first vision detection question, and returning to the step of executing the answering machine to obtain vision answer information, wherein the size of the characters corresponding to the third vision detection question is less than or equal to that of the characters corresponding to the first vision detection question;

and S77, when the continuous times reach the target times, determining the vision result of the tested object according to the vision answer information, sending the vision result to the processor, and returning to the answer device to obtain the identity answer information of the identity confirmation question.

When the answer result is the correct result, the answering machine needs to obtain each historical answer result of the tested object in the vision detection process, then the correct continuous times of answering are determined according to each historical answer result and the current answer result, and the correct result of the last time in the continuous times is the current answer result. For example, the subject has performed 5 responses of visual acuity tests in total, and the responses are sorted in the order from morning to evening, and the results are sequentially wrong, correct, and correct (the first four are historical responses, and the fifth is the current response), so that the number of times is 2. Therefore, when the current answer result is the correct result, the continuous times are updated.

The answering machine is provided with target times, the target times can be any suitable value, for example, 3 times, if the number of times of continuous correct answering is smaller than the target times, a third vision detection question needs to be generated according to the first vision detection question, because the answering result corresponding to the first vision detection question is a correct result, the size of characters in the third vision detection question is larger than or equal to the size corresponding to the characters in the first vision detection question, and at the moment, the execution of S60, the step S71, the step S72 and the step S73 needs to be returned to perform a new round of vision detection. If the correct times of continuous answering reaches the target times, the vision result of the tested object can be determined according to the current vision answering information, specifically, the answering machine acquires the vision detection problem corresponding to the current vision answering information, so that the position of the character corresponding to the vision detection problem in the vision chart is determined, the position corresponds to a vision value, and the vision value is the vision result of the tested object. The answering machine may then enter a new round of vision testing of the other eye of the test subject or the next test subject, after sending the vision results to the processor for recording in association with the test subject. It can be understood that, since the tested object is tested by one eye and the other eye is needed to perform vision test of the other eye after the left eye or the right eye of the tested object completes the vision test, there is a possibility that a certain tested object transfers the answering machine to the next tested object after completing the vision test of one eye and the next tested object continues the vision test without knowing the situation, which may cause a series of information confusion problems. In order to avoid such a problem, after each round of the steps of obtaining the vision result and associating the vision result with the tested object is completed, the processor sends an identity confirmation question to the answering machine, then the answering machine obtains answer information of the identity confirmation question to start a new round of vision detection, that is, after the step of associating the vision result with the tested object, the processor returns to the step of executing the step S20.

It should be noted that the target times may be determined according to the preset times and the current vision detection problem, for example, when the consecutive times reach the preset times, the vision detection apparatus determines the position of the character in the current vision detection problem, and then determines the position of the character in the previous vision detection problem, and if the positions of the two are located in the same row, the preset times may be the target times; if the positions of the two are not in the same row, it is further determined whether the vision result of the tested object is the vision corresponding to the character position in the current vision detection problem, that is, the preset number of times +1= the target number of times.

In this embodiment, the answering machine generates the next vision test question or obtains the vision result of the tested object according to the vision answer information corresponding to the current vision test question, that is, the generation of the vision test question and the determination of the vision result in the vision test process can be executed by the answering machine, the vision test process does not need manual participation, and the labor cost of the vision test is saved.

Optionally, the collector is provided with a first radio frequency module, and the answering machine is provided with a second radio frequency module in wireless communication connection with the first radio frequency module. The first radio frequency module and the second radio frequency module are in multi-channel communication connection, so that the use flexibility of the vision detection device is improved. Particularly, when a certain radio frequency channel cannot be used in the vision detection working environment, the first radio frequency module and the second radio frequency module can be flexibly adjusted to other channels to meet the working requirement. However, the design is not limited thereto, and in other embodiments, the collector and the answering machine may be connected through Wi-Fi or bluetooth for wireless communication.

Referring to fig. 1, the vision testing apparatus 110 further includes a holographic projection module 114 located between the test object and the eye chart 111, and the holographic projection module 114 is communicatively connected to the processor 112. The holographic projection module 114 is used for displaying the answer result each time, so as to increase the operation interest of the vision detection. For example, the characters corresponding to each vision detection problem are enlarged and projected to be displayed in front of the student, if the answer result is correct, the character image is inserted into the wing and flies upwards to gradually disappear or change a smiling face expression, and if the answer result is wrong, the character image is gradually cracked or changes a crying face expression, so that the interest of vision detection is enhanced. Particularly for use in younger groups such as pupils of lower grades.
