Description

Technical Field

[0001] The present invention relates to the field of perception testing technology, and in particular to a perception testing device with precise sensing and monitoring effects. Background Art

[0002] Depth perception, also known as "stereoscopic perception" or "distance perception," refers to the perception of objects in three dimensions or the distance between different objects. The retina can only receive stimulation in two dimensions; its response to three-dimensional space relies primarily on binocular vision. Depth perception is an essential instrument for psychology teaching experiments and is also widely used in depth perception-related job selection and training, such as for pilots, gunners, and athletes. Furthermore, the famous visual cliff experiment demonstrates that infants, even after they have learned to crawl, already possess quite good depth perception. Some children are born with depth perception deficits, and a key indicator of this deficit is the ability to perceive stereoscopically at different distances. Depth perception can be measured and demonstrated in nine modes: relative size of objects, occlusion, texture gradients, brightness and shadow, linear perspective, aerial perspective, motion parallax, binocular convergence, and binocular parallax. Currently, the only device capable of quantitatively measuring errors is the depth perception tester, which studies visual acuity in depth and measures the minimum threshold for binocular visual error in distance or depth.

[0003] Publication number CN118246788A discloses a method, device, electronic device, and medium for evaluating the comprehensive perceptual abilities of seafarers. The method comprises: constructing a test scenario for testing the perceptual abilities of seafarers; obtaining multiple evaluation index data input by the test seafarers based on the test scenario; the perceptual abilities include the ability to distinguish between light and sound signals, dynamic vision, dark and night vision, direction perception, time perception, motion perception, depth perception, and attention perception; and determining the evaluation results of the test seafarers' comprehensive perceptual abilities based on the multiple evaluation index data. By dividing the comprehensive perceptual abilities into the ability to distinguish between light and sound signals, dynamic vision, dark and night vision, spatial perception, time perception, motion perception, depth perception, and attention perception, the present invention constructs a multi-dimensional, comprehensive, and objective system for evaluating the comprehensive perceptual abilities of seafarers, addressing the problem that existing technologies lack comprehensive content in evaluating seafarers' professional abilities.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1

[0048] Reference Figures 1-9 ,This embodiment relates to depth perception testing;

[0049] During the actual test process, the recording personnel first starts the equipment. After the subject enters the test room, he sits facing the observation window 3. The subject selects the depth perception module through the previous button, next button, return button and confirmation button on the wireless control component 4. At this time, the signal sent by the wireless control component 4 is received by the receiving control component 5. The receiving control component 5 can control the PLC playback control component 6 and the corresponding lighting components in the observation window 3 to achieve the optimal shadowless effect in the observation window 3; avoid giving the subject corresponding prompts due to the appearance of projection, which affects the quality of the final test.

[0050] In this embodiment, the ambient light control component 12 installed in the box 1 can change the environmental conditions in the box 1, better increase the test environment conditions, and better perform depth perception testing.

[0051] In this embodiment, the motion adjustment component 10, the observation window 3 and the PLC playback control component 6 are arranged horizontally in their lengthwise direction; at the same time, the three comparison rods 71 ​​can all be observed through the observation window 3, and the belt motion component 75 in an observation and comparison component 7 is automatically started, and the component in the observation and comparison component 7 becomes a reference component, so that the moving port 73 drives the comparison rod 71 to move. At this time, the first infrared emitting component 72 corresponds to one of the infrared sensing components 92, and can realize the reception of infrared information data. The lengthwise direction of one of the infrared sensing components 92 is arranged perpendicular to the lengthwise direction of the PLC playback control component 6.

[0052] Among them, when the above-mentioned moving port 73 stops operating, the display broadcast component 2 will emit an indicator sound to remind the subject to be ready, and after the countdown, the belt motion component 75 on the other two observation and comparison components 7 will be started, so that the belt motion component 75 drives the moving port 73, the first infrared emission component 72 and the comparison rod 71 connected thereto to move. The subject can control the position of the moving port 73 by the depth and speed perception pause button on the wireless control component 4. At this time, the first infrared emission component 72 on the moving port 73 will also correspond to the other two infrared sensing components 92 to realize data transmission. The distance difference between the three first infrared emission components 72 can be quickly understood through the above data.

[0053] In this embodiment, when the reference observation and comparison component 7 stops operating, the subject can also be prompted to pay attention to observation. After that, the push-pull moving component 102 at the lower end of the observation and comparison component 7 is started to move the observation and comparison component 7 to the outside of the observation window 3 so that the subject can no longer observe it. The display broadcast component 2 can remind the subject to start the test, and the belt moving components 75 in the other two observation and comparison components 7 are operated to move the comparison rod 71 for depth testing. The distance difference between the three first infrared emitting components 72 can be understood through the cooperation of the infrared sensing component 92 and the first infrared emitting component 72.

[0054] Among them, the infrared data acquisition component 91 arranged at the lower end of the infrared sensing component 92 can receive the point where the infrared sensing component 92 receives the information of the first infrared emitting component 72, and can calculate the distance between the position and the infrared data acquisition component 91, so as to understand the depth perception ability of the subject through the deviation of the distance between the three first infrared emitting components 72 and the infrared data acquisition component 91. The above data can be quickly uploaded through the receiving control component 5, which is convenient for the staff to understand, and can also be effectively stored to form a depth perception test report of the subject.

[0055] Example 2

[0056] Reference Figures 1-9 ,This embodiment relates to a speed perception test;

[0057] During the actual test process, the motor assembly 103 is rotated to drive the mounting plate 101 to rotate, so that the longitudinal direction of the motion adjustment assembly 10 is set perpendicular to the longitudinal direction of the PLC playback control assembly 6 and the observation window 3. At the same time, the comparison rod 71 is set outside the observation window 3. At the same time, the data that need to be recorded by the infrared sensing assembly 92, the infrared data acquisition assembly 91 and the first infrared emission assembly 72 are: the operating speed of the belt motion assembly 75, the end points of the observation window 3 are based on the end points away from the side of the shielding member 84 as the starting point, the first infrared emission assembly 72 starts recording when it passes, and stops recording when it passes another point of the observation window 3. At the same time, the distance between the first infrared emission assembly 72 and the starting point is fully recorded. At the same time, the length distance of the observation window 3 is fixed data, and the distance of the shielding member 84 blocking the observation window 3 is also fixed data.

[0058] In this embodiment, the ambient light control component 12 installed in the box 1 can be used to change the environmental conditions in the box 1, thereby better increasing the test environment and better performing the speed perception test.

[0059] In this embodiment, when conducting the test, the subject can select the speed sensing module through the wireless control component 4. At this time, the PLC playback control component 6 in the box component 1 cooperates with the corresponding lighting component to enable the box component 1 to optimally achieve a shadowless environment; one of the belt motion components 75 is started to drive the comparison rod 71 to move, ensuring a constant speed, which is the reference speed, until the comparison rod 71 moves out of the range of the observation window 3, and the infrared sensing component 92 arranged parallel to the long direction of the observation window 3 receives the signal of the comparison rod 71 in the above-mentioned first infrared emission component 72 and records it to obtain comparison data. At the same time, the display broadcast component 2 starts broadcasting to prompt the subject to prepare for the test. When prompting the subject, the motor control component 88 operates to enable the screw telescopic component 87 to push the connecting plate 82 connected to it to descend, so that the shielding component 84 can follow the connecting plate 82 to descend, and the observation window 3 can be blocked. In addition, the use of shading materials can avoid light leakage and projection.

[0060] In this embodiment, after the preparation work is completed, that is, after the distance between the second infrared emitting component 85 and the infrared sensing component 92 at its lower end reaches the set distance, the motor control component 88 can stop operating, and the display broadcast component 2 prompts the subject to prepare for the test and implements the countdown prompt. Another belt motion component 75 can drive another comparison rod 71 to perform testing at a speed different from the reference speed. In order to facilitate recording and testing, the test speed can be set as an integer multiple of the reference speed for subsequent comparison.

[0061] The subjects estimated the time required for the comparison rod 71 to move out of the observation window 3 by observing the moving speed of another comparison rod 71 in the observation window 3 that was not blocked by the blocking member 84, and temporarily paused the operation by pressing the depth and speed perception pause button.

[0062] Among them, when the other comparison rod 71 starts to start, the infrared sensing component 92 arranged parallel to the long direction of the observation window 3 receives and records the signal of the first infrared emitting component 72. When the depth and speed perception pause button is pressed, the infrared sensing component 92 will also record the position of the other first infrared emitting component 72, and obtain the distance between the other first infrared emitting component 72 and the observation window 3 and the moving time of the other first infrared emitting component 72 through the preliminary data, so as to compare with the comparison data and determine the subject's perception of speed.

[0063] Then the third comparison rod 71 is controlled to operate for comparison.

[0064] In this embodiment, the other two first infrared emission components 72 can be moved at different speeds, and the speed perception of the test subject can be measured by recording the data.

[0065] Example 3

[0066] Reference Figures 1-9 ,This embodiment relates to time perception testing;

[0067] In this embodiment, the subject selects to perform a time perception test through the button on the wireless control component 4, and selects to perform a primary perception test or a perception training test, and sets the motion adjustment component 10 and the observation comparison component 7 to cooperate so that the comparison rod 71 is completely different from that observed through the observation window 3, and the shielding component 84 is reset to fully expose the observation window 3, and the primary perception test or the perception training test is started. The display broadcast component 2 broadcasts a reminder to the subject to prepare for the test, and the test is performed after the countdown is completed.

[0068] Among them, two groups of comparison films are set in the primary perception module, and the rhythm classification of the two groups of films is the same, that is, two films with slow rhythm are used as one group; two films with steady rhythm are used as one group; two films with fast rhythm are used as one group.

[0069] When the subjects are taking the test, the playing of the film group changes from slow to fast. For example, in the first test, the PLC playback control component 6 can play a slow-paced film for a certain period of time and then stop, then switch to another slow-paced film and play it again. After the subjects determine that the playing time of the two films is the same, they press the time perception pause button on the wireless control component 4 to stop playing, and the PLC playback control component 6 records the playing time of the two films.

[0070] Then, comparative tests of steady-paced films and fast-paced films were conducted in turn, and the test data were recorded to understand the time perception ability of the subjects.

[0071] In this embodiment, a perception training module is also provided, in which the two groups of videos used for comparison have different rhythms. The video played first can be a video with a steady rhythm. After setting the playback time, the comparison video can be a video with a slow rhythm or a fast rhythm, so as to facilitate the subjects to exercise their time perception.

[0072] In actual testing, the corresponding data are measured and recorded through the infrared data acquisition component 91, the infrared sensing component 92, the first infrared emission component 72, the belt motion component 75, the second infrared emission component 85, the PLC playback control component 6 and the receiving control component 5, and can also be connected to the corresponding computer components to quickly input the collected data to form corresponding tables or perform comparative calculations.

[0073] In this embodiment, the receiving control component 5 is connected to the wireless control component 4, can sense the button pressing on the wireless control component 4, can control the automated components in the observation and comparison component 7 and the motion adjustment component 10 through the receiving control component 5, and can also be connected to the display broadcast component 2, play the selection of the wireless control component 4 through the display broadcast component 2, and after confirmation, broadcast according to the process data, which is convenient for the subjects to take measurements. At the same time, the display broadcast component 2 and the receiving control component 5 are connected, and after the broadcast, the receiving control component 5 can control the PLC playback control component 6, observation and comparison component 7, shielding component 8 and motion adjustment component 10 to perform corresponding operations. At the same time, the receiving control component 5 can be connected to the infrared detection component 9 to facilitate data collection.

[0074] In this embodiment, the data collected by the infrared data acquisition component 91, the infrared sensing component 92, the first infrared emission component 72, the belt motion component 75, the second infrared emission component 85 and the PLC playback control component 6 include:

[0075] The distance between the corresponding point of the infrared data acquisition component 91 and the first infrared emission component 72 and the lower end of the infrared sensing component 92; the distance between the corresponding point of the infrared data acquisition component 91 and the first infrared emission component 72 and the long ends of the observation window 3; the distance between the second infrared emission component 85 and the infrared sensing component 92; the length of the film played by the PLC playing control component 6; the rotating speed of the belt movement component 75; the time, depth and speed perception test conditions can be perceived through the determination of the above data; and after the data is recorded, the corresponding data can be quickly collected by the receiving control component 5, and the data is transmitted to the computer equipment connected with the receiving control component 5, and the corresponding database is set in the computer equipment, so as to be stored and calculated quickly according to the corresponding formula. The formula can adopt the existing perception test formula.

[0076] For example, in the case of time perception measurement, the absolute error (absolute error, AE), the relative error (Ratio) and the coefficient of variation (CV) indicators; wherein, AE=(copying time-standard time) / standard time, the larger the AE, the greater the individual time

[0077] The lower the accuracy of the copy: Ratio=copying time / standard time, and the score is greater than 1, indicating that the individual overestimates (overestimates) the standard time; CV=standard deviation / average copying time, which reflects the consistency of judging the target time interval.

[0078] In the present application, the testee can wear the head detection component 11 on the head, and the testee can be detected by the electroencephalogram during the test, so as to understand the position of the active brain region of the testee during different tests, and the monitoring principle of the monitoring scheme is the prior art, which does not need to be described in detail, and the detected data can be uploaded, which is convenient for the technical personnel in the field and the brain science to be linked.

[0079] In the present application, the corresponding components are arranged in the display broadcast component 2, and the corresponding PLC control component is arranged, the corresponding program is arranged in advance, which is divided into three modules, corresponding to depth, speed and time perception test respectively. After the testee selects the corresponding test, the corresponding module can be entered, and after the signal receiving module receives the corresponding information, the voice broadcast module and the voice receiving module can be controlled to operate, so as to effectively prompt, for example, when the depth perception is carried out, the following prompt is carried out first:

[0080] Firstly, the display broadcast component 2 issues: whether to carry out depth perception test, please answer: yes or no; in order to perceive the voice of the testee for the next step (voice perception and through perception into the corresponding program are prior art, which need not be further described);

[0081] If the answer is yes, the second step is to display the broadcast component 2: after the "drop" sound, the depth perception test is carried out, first, the first contrast rod 71 moves and stops moving after the "beep" sound;

[0082] When the first contrast rod 71 moves and stops, the third step is carried out, and the display broadcast component 2 is prompted: please press the "confirm" key to control the second contrast rod 71 to move; and press the "depth, speed perception pause" key to stop operation;

[0083] And after pressing the "depth, speed perception pause" key, the display broadcast component 2 prompts the third contrast rod 71 to operate, and after pressing the "depth, speed perception pause" key again, the display broadcast component 2 broadcasts that the first set of perception test is completed, and the test result is recorded in the test; and prompts to test for the second time, and each test can be set to multiple sets of tests according to needs, so as to improve the test effect.

[0084] In actual operation, corresponding settings can be made according to needs, and the setting principle and corresponding operation components are prior art, and do not need to be specifically described.

[0085] The speed and time can also be set according to needs. Sound prompts are set to provide operation guidance for the test personnel.

[0086] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
