[0017] Figure 1 4 is a structural block diagram of a vestibular-ocular reflex function detection and evaluation system according to a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, this embodiment provides a vestibular-ocular reflex function detection and evaluation system, which includes a treadmill 100, a random screen projection device 200, a wireless transponder 300 and a control host 400, and the wireless transponder 300 has a letter E with different opening directions.

[0020] The control host 400 is used to control the random screen projection device 200 to randomly project the letter E of different font sizes and opening directions on the screen when the person being tested is in a stationary state, and all the letters E of different font sizes are projected, and the projection start timestamp, font size and opening direction of each letter E are recorded; receive the response signal sent by the person being tested through the wireless transponder 300 for each letter E projected, record the response timestamp of the response signal and identify the opening direction of the letter E in the response signal, analyze and record the font size of each letter E projected, the reaction time of the person being tested, and whether the person being tested accurately identifies the opening direction of the letter E.

[0021] The response time of the subject corresponding to the letter E = the response timestamp of the letter E - the delivery start timestamp of the letter E.

[0022] Whether the person being tested accurately identifies the opening direction of the letter E: if the opening direction of the letter E is consistent with the opening direction of the letter E in the response signal, the person being tested accurately identifies the opening direction of the letter E; otherwise, the person being tested does not accurately identify the opening direction of the letter E.

[0023] Test subject response plan: The test subject is equipped with a wireless transponder. After seeing the letter E on the screen, the test subject presses the corresponding button on the wireless transponder to indicate the opening direction of the letter E. The transponder is wirelessly connected to the control host to ensure that the test subject's operation is convenient and fast during the test, and the test subject's reaction time and answer can also be accurately recorded.

[0024] Furthermore, when the person being tested is in a stationary state, for a certain letter E that is placed, determine whether the reaction time of the person being tested corresponding to this placed letter E is greater than the preset stationary feedback time. If so, it indicates that the reaction time of the person being tested is too long, and the answer of the person being tested is a random guess, not observed by the eyes, and needs to be tested again. Then, a letter E with the same font size as the letter E placed this time and a different opening direction is placed again, until the reaction time of the person being tested corresponding to the letter E placed again is no greater than the corresponding preset stationary feedback time, and then proceed to the placement of the next letter E with a different font size, analyze and record the font size of each letter E placed corresponding to the reaction time of the person being tested within the preset stationary feedback time, the reaction time of the person being tested, and whether the person being tested accurately identifies the opening direction of the letter E.

[0025] For example: in a stationary state, the person being tested stands next to a treadmill or on a stationary treadmill 100, and the person being tested is in a stationary state, facing the screen for vision testing. At this time, the random projection device 200 randomly projects the letter E of different font sizes and opening directions on the screen, and all the letters E of different font sizes are projected. The images of these letters E enter the eyes of the person being tested through light reflection, and the retina of the human eye receives the light signal and converts it into a neural signal and transmits it to the visual center of the brain for processing. After the person being tested visually identifies the opening direction of the letter E, he presses the button of the letter E corresponding to the opening direction on the wireless transponder 300. In this way, the wireless transponder 300 transmits the response signal of the person being tested to the control host 400. The control host 400 records the recognition accuracy of the person being tested for the letters E of different sizes (whether the person being tested accurately identifies the opening direction of the letter E), the font size, and the reaction time from the appearance of the letter E to pressing the button.

[0026] The control host 400 is also used to control the treadmill 100 to provide different movement speeds and movement slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states, the random screen projection device 200 is controlled to randomly project the letter E of different font sizes and opening directions on the screen, and all font sizes of the letter E are projected, and the start timestamp of the projecting of each letter E and the font size and opening direction are recorded in each exercise intensity state. The response signal sent by the subject through the wireless transponder for each letter E projected in each exercise intensity state is received, and the response timestamp of the response signal and the opening direction of the letter E in the identified response signal are recorded. The font size of each letter E projected in each exercise intensity state, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E are analyzed and recorded, and N is a positive integer.

[0027] Furthermore, when the subject is in any state of motion intensity, for a certain letter E that is placed, determine whether the subject's reaction time corresponding to this placed letter E is greater than the preset motion feedback time corresponding to the motion intensity. If so, it indicates that the subject's reaction time is too long, and the subject's answer is a random guess, not observed by the eyes, and needs to be tested again. Then, a letter E with the same font size as the letter E placed this time and a different opening direction is placed again, until the subject's reaction time corresponding to the letter E placed again is no greater than the corresponding preset motion feedback time, and then proceed to the next placement of a letter E with a different font size. Analyze and record the font size of each letter E placed corresponding to the subject's reaction time within the corresponding preset motion feedback time under each motion intensity state, the subject's reaction time, and whether the subject accurately identifies the opening direction of the letter E.

[0028] When entering the motion state detection, the person being tested runs on the treadmill 100, and the speed and slope of the treadmill 100 can be adjusted to simulate different exercise intensities. During the running process, the body of the person being tested is in motion, and the head and eyeballs will produce motion-related changes such as shaking. At the same time, the random projection device still projects the letter E on the screen. The person being tested observes the letter E in motion, the retina receives the constantly changing light signals, and the visual center of the brain processes these signals under the interference of body movement. The person being tested makes a judgment on the opening direction of the letter E in the motion state and sends a signal to the control host 400 through the wireless transponder 300. The control host 400 also records the recognition accuracy of the letter E of different sizes under different exercise intensities of the person being tested (whether the person being tested accurately recognizes the opening direction of the letter E), the font size, and the reaction time from the appearance of the letter E to pressing the button. By comparing the data in the static state and the motion state, the difference in visual resolution between the static and motion states can be analyzed.

[0029] In the static state, the subject stands beside the treadmill or on the static treadmill, faces the screen, observes the letter E on the screen, and undergoes a vision test. In the dynamic state, the subject runs on the treadmill, observes the letter E on the screen, and undergoes a vision test.

[0030] The control host 400 is also used to analyze the minimum font size for the subject to accurately identify the opening direction of the letter E in a static state, and the minimum font size for the subject to accurately identify the opening direction of the letter E in each motion intensity state, and calculate the actual difference between the minimum font size for the subject to accurately identify the opening direction of the letter E in each motion intensity state and the minimum font size for the subject to accurately identify the opening direction of the letter E in a static state to obtain N actual difference values, and fit the function f(x)=ax+b to the N actual difference values ​​to obtain the a value, and determine whether the a value is greater than a set threshold. If so, output information that the subject's vestibular-ocular reflex function is impaired, otherwise output information that the subject's vestibular-ocular reflex function is normal.

[0031] This embodiment also provides a method for detecting and evaluating vestibular-ocular reflex function, which comprises the following steps:

[0032] When the person being detected is in a stationary state, the control host 400 controls the random screen projection device 200 to randomly project the letter E of different font sizes and opening directions on the screen, and all font sizes of the letter E are projected, and the projected start timestamp, font size and opening direction of each letter E are recorded; a response signal sent by the person being detected through the wireless transponder 300 for each projected letter E is received, and the response timestamp of the response signal and the opening direction of the letter E in the identified response signal are recorded; the font size of each letter E projected, the reaction time of the person being detected, and whether the person being detected accurately identifies the opening direction of the letter E are analyzed and recorded; the reaction time of the person being detected corresponding to the letter E = the response timestamp of the letter E - the projected start timestamp of the letter E; whether the person being detected accurately identifies the opening direction of the letter E: if the projected opening direction of the letter E is consistent with the opening direction of the letter E in the response signal, then the person being detected accurately identifies the opening direction of the letter E; otherwise, the person being detected does not accurately identify the opening direction of the letter E.

[0033] When the subject is in a static state, for a certain letter E placed, determine whether the subject's reaction time corresponding to the letter E is greater than the preset static feedback time. If so, place a letter E again with the same font size as the letter E placed but with a different opening direction, until the subject's reaction time corresponding to the letter E placed again is no greater than the preset static feedback time, then proceed to place the next letter E with a different font size, analyze and record the font size of each letter E placed corresponding to the subject's reaction time within the preset static feedback time, the subject's reaction time, and whether the subject accurately identifies the opening direction of the letter E.

[0034] The control host 400 controls the treadmill 100 to provide different movement speeds and movement slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states, the random screen projection device 200 is controlled to randomly project the letter E of different font sizes and opening directions on the screen, and all font sizes of the letter E are projected, and the projected start timestamp, font size and opening direction of each letter E in each exercise intensity state are recorded. The response signal sent by the subject through the wireless transponder 300 for each projected letter E in each exercise intensity state is received, and the response timestamp of the response signal and the opening direction of the letter E in the identified response signal are recorded. The font size of each letter E projected in each exercise intensity state, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E are analyzed and recorded, and N is a positive integer.

[0035] When the subject is in any state of motion intensity, for a certain letter E placed, determine whether the subject's reaction time corresponding to the placed letter E is greater than the preset motion feedback time corresponding to the motion intensity. If yes, place a letter E again with the same font size as the placed letter E and a different opening direction, until the subject's reaction time corresponding to the second placed letter E is no greater than the corresponding preset motion feedback time, and then proceed to place the next letter E with a different font size. Analyze and record the font size of each placed letter E corresponding to the subject's reaction time within the corresponding preset motion feedback time under each motion intensity state, the subject's reaction time, and whether the subject accurately identifies the opening direction of the letter E.

[0036] The control host 400 analyzes the minimum font size for the subject to accurately identify the opening direction of the letter E in a static state, and the minimum font size for the subject to accurately identify the opening direction of the letter E in each motion intensity state, and calculates the actual difference between the minimum font size for the subject to accurately identify the opening direction of the letter E in each motion intensity state and the minimum font size for the subject to accurately identify the opening direction of the letter E in a static state to obtain N actual difference values, and fits the function f(x)=ax+b to the N actual difference values ​​to obtain a value, and determines whether the a value is greater than a set threshold. If so, outputs information that the subject's vestibular-ocular reflex function is impaired, otherwise, outputs information that the subject's vestibular-ocular reflex function is normal.
