[0066] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0067] From the perspective of different levels of perception by the subjects, visual field can be divided into central visual field and peripheral visual field. Central visual field is the area directly in front of the subject, where visual information can be clearly perceived and processed. Peripheral visual field is the area that the subject can perceive with their peripheral vision. Although the subject can perceive the movement or changes of objects in this area, the details and shapes of the objects may not be as clear.
[0068] Regarding the range of central and peripheral visual fields, generally speaking, the central visual field covers approximately 10-30 degrees, primarily controlled by the fovea centralis. The peripheral visual field, on the other hand, extends beyond 30 degrees. It's important to note that this division is not absolute, as individual differences and environmental factors can all influence the actual range of visual field.
[0069] From the perspective of eye movement and the function of the visual system, peripheral vision can be divided into dynamic vision and static vision. Dynamic vision refers to the peripheral range that a subject can perceive when the eyes can move. Static vision, on the other hand, refers to the peripheral range that a subject can perceive when the eyes are stationary. This division is mainly based on the function of eye movement and the visual system.
[0070] To improve the relevance and accuracy of peripheral vision testing methods, the human eye's visual field is divided into horizontal and vertical visual fields. The vertical visual field, or the field of vision in the vertical plane, can include angles above and below the standard line of sight. Peripheral perception in the vertical plane is extremely important for professionals, such as drivers who need to be aware of vertical height restrictions (e.g., bridges, tunnels, overpasses, interchanges, etc., or other easily overlooked structures like power lines, pipes, and overhead facilities). Therefore, this specification proposes a system for testing and training a subject's visual perception ability in the vertical direction, namely, a vertical peripheral perception ability testing and training system.
[0071] For example, in the field of driving, drivers need a wide field of vision in the vertical direction to promptly detect traffic signals, obstacles, and other vehicles on the road. Visual field tests assess a driver's field of vision and sensitivity, ensuring they possess the visual conditions necessary for safe driving. Visual field tests can detect whether drivers have narrow fields of vision, blind spots, or other visual problems, allowing for appropriate training and measures to improve driving safety.
[0072] For example, in the security field, especially in professions requiring high vigilance and rapid response, such as firefighters and police officers, a broad vertical field of vision is crucial for protecting individual and public safety. Visual field testing assesses the visual perception capabilities of professionals in complex and high-pressure environments, ensuring they can fully perceive potential dangers and threats. Visual field testing helps identify visual impairments and deficiencies, and provides appropriate training and equipment, improving professionals' reaction speed and decision-making abilities in emergency situations, thereby maintaining public safety.
[0073] For example, in the medical and health field, testing vertical peripheral perception ability can help identify whether an individual has a visual perception deficit in the vertical plane, and can help doctors conduct training to enhance the individual's vertical peripheral perception ability. It should be emphasized that, since this method targets the vertical peripheral perception ability of the test subject, the implementation method in this specification first requires keeping the subject's head and eyes relatively still in the vertical direction, while not restricting the left and right rotation of the subject's eyes in the horizontal direction.
[0074] It should be noted that "tendency to remain still" can be understood as maintaining relative stability, meaning no movement or only minor movement within a predetermined permissible range during the test. For example, "tendency to remain still" could mean that the subject's head remained stationary during the test, or that the subject's head made minor movements within a predetermined permissible range. Similarly, "tendency to remain still" in the vertical direction could mean that the subject's eyes did not move vertically during the test, or that the subject's eyes made minor movements within a predetermined permissible range in the vertical direction.
[0075] Please see Figure 1a This specification provides a test and training system for vertical peripheral perception capability in a scenario example. The test and training system 100 includes a main display screen 102, a first display screen 104, and a second display screen 106 distributed vertically. The first display screen 104 and the second display screen 106 are located on opposite sides of the main display screen 102. The first display screen 104 is equipped with a first Time-of-Flight (TOF) module 108 and a second TOF module 110. The second display screen 106 is equipped with a third TOF module 112 and a fourth TOF module 114.
[0076] In this scenario example, the main display screen 102 can display a first target object (such as a crosshair) to guide the subject's gaze towards the first target object and maintain the subject's head and eye movement relatively still. The first display screen 104, together with the second display screen 106, displays interfering visual information in the form of images or illuminated pixels. This interfering visual information simulates the real-world environment in which the subject performs a target task (such as driving a vehicle). It should be noted that by guiding the subject's gaze towards the first target object and focusing their line of sight on the main display screen 102, the subject can use peripheral vision in the vertical direction to perceive the first display screen 104 and the second display screen 106.
[0077] In this scenario example, the first display screen 104 and the second display screen 106 are the same size. If a first target object (such as a hollow circle) is displayed at the center of the main display screen 102 to guide the subject's gaze, the subject's line of sight to the first target object is on the same horizontal line as the center line 116 of the main display screen. The edge of the first display screen 104 near the main display screen 102 is in contact with the edge of the main display screen 102 near the first display screen 104. The edge of the second display screen 106 near the main display screen 102 is in contact with the edge of the main display screen 102 near the second display screen 106.
[0078] In this example scenario, please refer to Figure 1b The first display screen 104 and the second display screen 106 each have a first position 118 and a second position 120 symmetrically positioned relative to the center line 116 of the main display screen. The angle formed vertically between the subject's line of sight to the first target object and the first position 118 is recorded as the first angle. The angle formed vertically between the subject's line of sight to the first target object and the second position 120 is recorded as the second angle. This configuration ensures that the first angle equals the second angle, which is beneficial for accurately testing the subject's maximum viewing angle and maximum resolution viewing angle or viewing angle range.
[0079] In this example scenario, the first TOF module 108 corresponds to a first signal coverage area in the test space. The second TOF module 110 corresponds to a second signal coverage area in the test space. The third TOF module 112 corresponds to a third signal coverage area in the test space. The fourth TOF module 114 corresponds to a fourth signal coverage area in the test space. The first, second, third, and fourth signal coverage areas overlap with each other; this overlapping area is defined as the specified area for the subject, meaning the subject's head must appear within this specified area.
[0080] In this scenario example, the subject's head is determined to be within the designated area if all four TOF modules (108, 110, 112, and 114) receive the reflected signals. If at least some of these modules fail to receive the reflected signals, the subject's head is determined to be outside the designated area. Furthermore, a reminder message can be issued to prompt the subject to move so that their head appears within the designated area. After confirming that the subject's head is within the designated area, testing or training of the subject's vertical visual perception ability can begin.
[0081] Please see Figure 1c The test and training system also includes a processing unit 122 (such as a microcontroller), a power supply circuit 124, and a feedback unit 126 (such as at least one of a foot pedal and a button).
[0082] In this scenario example, the power supply circuit 124 supplies power to the main display screen 102, the first display screen 104, and the second display screen 106. The processing unit 122 is connected to the main display screen 102, the first display screen 104, the second display screen 106, the first TOF module 108, the second TOF module 110, the third TOF module 112, and the fourth TOF module 114, respectively. The processing unit 122 controls the main display screen 102 to display the first target object. The processing unit 122 controls the first display screen 104 and the second display screen 106 to display visual interference information (interference points), respectively. The processing unit 122 controls the first display screen 104 to display the second target object at a first moment. The processing unit 122 controls the second display screen 106 to display the second target object at a second moment.
[0083] In this scenario example, during the subject's fixation on the first target object, the first display screen 104 can display a second target object (such as any one of a specific image, a specific shape, or a specific shape). The second target object serves as a stimulus point to visually stimulate the subject. If the subject perceives the stimulus point (the second target object), and if the subject triggers the feedback unit 126 within a preset time period, the feedback unit 126 sends trigger information to the processing unit 122, indicating that the subject has perceived the stimulus point. If the subject does not trigger the feedback unit 126 within the preset time period, and the processing unit 122 does not receive trigger information within the preset time period, it indicates that the subject did not perceive the stimulus point in time.
[0084] In this example scenario, please refer to Figure 1dThe processing unit 122 may integrate a vertical field of view assessment unit 128. The feedback unit 126 receives the subject's perceptual feedback information in response to the subject's triggering operation. The feedback unit 126 sends the perceptual feedback information to the vertical field of view assessment unit 128. The vertical field of view assessment unit 128 receives the perceptual feedback information sent by the feedback unit 126 and determines the subject's maximum vertical viewing angle and / or viewing angle range based on the perceptual feedback information and the location of the second target object.
[0085] In this scenario example, the main display screen 102, the first display screen 104, and the second display screen 106 can be either flat screens or curved screens. Alternatively, the main display screen 102, the first display screen 104, and the second display screen 106 can be LED dot matrix screens.
[0086] This specification provides a testing and training system for vertical perimeter perception capabilities. Please refer to [link to relevant documentation]. Figure 2a The testing and training system 100 includes a display unit 210 and a feedback unit 126. The display unit 210 has an eye fixation area 220 and a stimulus display area 230 distributed along the vertical direction. Wherein:
[0087] The eye fixation area 220 is used to display the first target object 240 to guide the subject 250 to fixate on the first target object 240 and to keep the subject 250's head and eyes tending to remain still in the vertical direction.
[0088] The stimulation display area 230 is used to display the second target object 260 during the subject 250's fixation on the first target object 240, so as to stimulate the subject 250 to perceive the second target object 260.
[0089] Feedback unit 126 is used to collect and output perceptual feedback information of the subject 250 to the second target object. The perceptual feedback information and the location of the second target object are used to determine the vertical peripheral perceptual range of the subject 250.
[0090] In this embodiment, the display unit 210 can be a device for displaying at least one of a specified image, specified text, specified geometric shape, etc. The display unit 210 can consist of a flat panel and a number of light-emitting diodes (LEDs) distributed thereon. Alternatively, the display unit 210 can consist of a curved panel and a number of light-emitting diodes (LEDs) distributed thereon. Exemplarily, the display unit 210 can be any type of panel selected from liquid crystal displays (LCDs), organic light-emitting diode displays (OLEDs), and plasma displays (PDPs). Exemplarily, the pixels of the display unit 210 can be composed of small-sized light-emitting diodes (LEDs) or liquid crystal display units. Each pixel can have its brightness or color changed by controlling electrical signals, and different images, shapes, patterns, etc., can be formed on the display unit 210. Depending on the number and arrangement of pixels, the display unit 210 can be classified as a monochrome dot matrix screen or a color dot matrix screen.
[0091] In this embodiment, since the visual field can be divided into the central visual field and the peripheral visual field, in order to test or train the subject 250's visual perception ability in the vertical direction, the display unit 210 can be provided with an eye fixation area 220 and a stimulus display area 230 distributed in the vertical direction. By guiding the subject 250 to fixate on the first target object 240 in the eye fixation area 220, the subject 250's head is kept as still as possible. Furthermore, in order to test the vertical peripheral perception ability, it is necessary to keep the subject 250's eyeballs as still as possible in the vertical direction. Specifically, the first target object 240 can be understood as a mark or image displayed at a specified position (e.g., the center position) in the eye fixation area 220. The first target object 240 guides and assists the subject 250's standard line of sight as the subject fixates their central visual field on the eye fixation area 220. For example, by guiding the subject 250 to fixate on the first target object 240, the subject 250's standard line of sight is fixed on the first target object 240 or at the same horizontal plane as the first target object, thus meeting the prerequisite for testing vertical peripheral perception ability and improving the test or training results of vertical peripheral perception ability. It should be noted that in this embodiment, there is no restriction on the subject's eye movement in the horizontal direction. The movement of the subject's eyes can be determined by eye-tracking technology.
[0092] In this embodiment, by guiding the subject 250 to gaze at the first target object 240 within the eye-focusing area 220, a stimulus display area 230 adjacent to the eye-focusing area 220 can be set in the vertical direction to test or train the subject's peripheral vision perception ability. It is understood that there may be a gap between the eye-focusing area 220 and the stimulus display area 230, or the eye-focusing area 220 may be directly adjacent to the stimulus display area 230. The number of stimulus display areas 230 can be one, two, or more. If there is one, the stimulus display area 230 can be located above or below the eye-focusing area 220. If there are two or fewer, some of the stimulus display areas 230 may be located above the eye-focusing area 220, and some may be located below the eye-focusing area 220. For example, please refer to [link to example description]. Figure 2b A stimulus display area 230 is provided above and below the eye gaze area 220.
[0093] Furthermore, during the subject 250's fixation on the first target object 240, a second target object 260 is displayed in the stimulation display area 230 to stimulate the subject 250 to perceive the second target object 260, thereby checking whether the subject can perceive the second target object 260 in the vertical direction using peripheral vision. Finally, the subject 250's visual perception ability in the vertical direction is evaluated based on the perception feedback information of the second target object 260.
[0094] In this embodiment, the eye fixation area 220 can be located within the central visual field of the subject. The stimulus display area 230 can be located within the peripheral visual field of the subject. The second target image 260 is determined by pixels in the stimulus display area 230 that are suddenly lit or turned off. The second target image 260 stimulates the subject to perceive the subject's peripheral vision in the vertical direction, thereby testing or training the subject's vertical peripheral perception ability.
[0095] In this embodiment, when the subject 250 perceives the second target object, the subject 250 can trigger the feedback unit 126. The feedback unit 126 collects and outputs the subject 250's perception feedback information of the second target object. The second target object has a corresponding location, and the location of the second target object can reflect the subject 250's perspective. Therefore, the subject 250's vertical peripheral perception range is determined based on the subject 250's perception feedback information of the second target object and the location of the second target object.
[0096] In some implementations, the second target object may be displayed in one or a combination of the following ways: lighting up a specified number of pixel rows, specifying a geometric shape, specifying a pattern, appearing at random times, appearing at random positions, appearing in a preset time order, or appearing in a preset position order.
[0097] It should be noted that the eye-focusing area and the stimulus display area can be provided by a single display device, that is, by dividing the display area of the display device into eye-focusing areas and stimulus display areas distributed along the vertical direction. Alternatively, the eye-focusing area and the stimulus display area can be provided by two display devices, that is, one display device provides the eye-focusing area, and the other display device provides the stimulus display area.
[0098] In the above embodiments, by setting an eye-focusing area and a stimulation display area distributed along the vertical direction on the display unit, the visual perception ability of the subject in the vertical direction is tested or trained. During the test, on the one hand, the subject is guided to look at the first target object through the eye-focusing area, and the subject's head and eyes are kept relatively still in the vertical direction. On the other hand, while the subject is focusing on the first target object, the stimulation display area displays a second target object to stimulate the subject to perceive the second target object with peripheral vision. Based on the perception feedback information and the appearance position of the second target object, the subject's vertical peripheral perception range is determined, and the subject's visual perception ability in the vertical direction is evaluated, thus realizing a new testing and training system for vertical peripheral perception ability.
[0099] In some implementations, please refer to Figure 2c The testing and training system also includes a feedback unit 126 and a processing unit 122 connected to the feedback unit 126. The feedback unit 126 is used to collect and output perceptual feedback information of the subject to the second target object. The processing unit 122 is used to receive the perceptual feedback information sent by the feedback unit and, based on the perceptual feedback information and the location of the second target object, determine the subject's vertical peripheral perceptual range, maximum viewing angle, and / or viewing angle range in the vertical direction.
[0100] Perceptual feedback can be an interactive feedback mechanism by which the subject perceives a stimulus signal during the test. Perceptual feedback can be expressed or manipulated in various ways to indicate whether the subject has perceived the stimulus signal. For example, perceptual feedback can be interactive feedback through monitoring mouse click events. For instance, when a second target object is displayed on the screen, the subject clicks the mouse to indicate that they have perceived the stimulus of the second target object. Perceptual feedback can also be interactive feedback through monitoring keyboard events. For instance, when a second target object is displayed on the screen, the subject presses a designated key on the keyboard to indicate that they have perceived the stimulus of the second target object. Perceptual feedback can also be interactive feedback through monitoring foot pedal events. For instance, when a second target object is displayed on the screen, the subject presses a foot pedal to indicate that they have perceived the stimulus of the second target object. Finally, perceptual feedback can be interactive feedback through monitoring controller events. For instance, when a second target object is displayed on the screen, the subject performs a specific operation using a controller to indicate that they have perceived the stimulus of the second target object.
[0101] Specifically, the vertical visual field includes the angles above and below the standard line of sight. To accurately test or train the subject's vertical peripheral perception ability, the eye fixation area is set within the subject's central visual field, while the stimulus display area is set within the corresponding area in the vertical direction of the peripheral visual field. The eye fixation area displays a first target object, guiding the subject to focus on the first target object while keeping the subject's head and eyes relatively still in the vertical direction. While the subject is fixating on the first target object, the stimulus display area displays a second target object, which the subject perceives in the vertical direction using peripheral vision.
[0102] To promptly determine whether the subject has perceived a second target object appearing vertically using their peripheral vision, the testing and training system includes a feedback unit. The subject perceives the second target object vertically using their peripheral vision. If the subject triggers the feedback unit within a preset time period, it indicates that the subject has perceived the stimulus of the second target object within that time period. If the subject does not trigger the feedback unit within the preset time period, it indicates that the subject has not perceived the stimulus of the second target object within that time period. The feedback unit is connected to a processing unit. The processing unit receives the perception feedback information sent by the feedback unit and, based on the perception feedback information and the location of the second target object, determines the subject's maximum visual angle and / or visual angle range in the vertical direction. The visual angle range may include the visual angle corresponding to the highest resolution in the vertical direction.
[0103] For example, a second target object is displayed at a first position in the stimulus display area at the current moment, and the feedback unit collects and outputs the subject's current perceptual feedback information. The processing unit can determine a second position in the stimulus display area for displaying the second target object at the next moment based on the current perceptual feedback information. For instance, if the current perceptual feedback information indicates that the subject can perceive the stimulus of the second target object within a preset duration, a second position is determined in a region further outward from the eye's gaze area. This process continues, continuously moving the position of the second target object in the stimulus display area outward until the subject no longer perceives the stimulus of the second target object within the preset duration. At this point, it indicates that the position has exceeded the subject's vertical peripheral perception range.
[0104] For example, a second target object can be displayed at a first position in the stimulus display area at the current moment, and the subject's current perceptual feedback information can be collected and output through the feedback unit. The second position for displaying the second target object in the stimulus display area at the next moment can be determined according to pre-set display rules, and the subject's next-moment perceptual feedback information can be collected and output through the feedback unit. This process continues, allowing the processing unit to obtain perceptual feedback information from the subject at multiple moments. The processing unit performs statistical analysis on the perceptual feedback information from multiple moments to determine the subject's vertical peripheral perceptual range.
[0105] In some implementations, please refer to Figure 3 The stimulation display area 230 includes a first display area 310 and a second display area 320. The first display area 310 and the second display area 320 are located on both sides of the eye gaze area 220 and are symmetrically arranged with respect to the eye gaze area 220.
[0106] In some cases, the vertical field of vision includes the angle above the standard line of sight and the angle below the standard line of sight. In order to accurately test or train the subject's vertical peripheral perception ability, the eye fixation area is set within the subject's central field of vision, and the stimulus display area, including the first display area and the second display area, is set in the corresponding area in the vertical direction of the peripheral field of vision. Thus, the first display area and the second display area are located on both sides of the eye fixation area.
[0107] For details, please continue reading Figure 3The first display area 310 and the second display area 320 are located on either side of the eye-focusing area 220, for example, the first display area 310 is located above the eye-focusing area 220, and the second display area 320 is located below the eye-focusing area 220. A preset distance may exist between the first display area 310 and the eye-focusing area 220, and the same preset distance may also exist between the second display area 320 and the eye-focusing area 220, so that the first display area 310 and the second display area 320 are symmetrically arranged relative to the eye-focusing area 220. For example, the subject's standard line of sight may be on the same horizontal plane as the center line of the eye-focusing area 220, and the first display area 310 and the second display area 320 may be symmetrically arranged relative to the center line of the eye-focusing area 220.
[0108] It should be noted that the first display area 310 and the second display area 320 can have the same size.
[0109] It should be noted that the eye-focusing area, the first display area, and the second display area can be provided by a single display device, that is, by dividing the display area of the display device to obtain the eye-focusing area, the first display area, and the second display area distributed along the vertical direction. Alternatively, the eye-focusing area, the first display area, and the second display area can be provided by three display devices, that is, one display device provides the eye-focusing area, one display device provides the first display area, and one display device provides the second display area.
[0110] In this embodiment, the first display area and the second display area are symmetrically arranged on both sides of the eye's gaze area. This ensures that the two symmetrical positions in the first display area and the second display area are consistent with the relative positions of the subject's eyeballs, which facilitates subsequent evaluation of the subject and improves the accuracy of testing or training results.
[0111] In some implementations, please refer to Figure 4a The center of the eye-focusing area 220 is approximately at the same horizontal level as the subject's line of sight 410 when focusing on the first target object. The edge of the eye-focusing area 220 near the first display area 310 is positioned to contact the edge of the first display area 310 near the eye-focusing area 220. The edge of the eye-focusing area 220 near the second display area 320 is positioned to contact the edge of the second display area 320 near the eye-focusing area 220.
[0112] The preset distance between the first display area 310 and the eye-focusing area 220 is equal to the preset distance between the second display area 320 and the eye-focusing area 220, and this preset distance can be equal to 0. Specifically, the first display area 310 and the second display area 320 are arranged adjacent to each other on both sides of the eye-focusing area 220, that is, the edge of the eye-focusing area 220 near the first display area 310 is in contact with the edge of the first display area 310 near the eye-focusing area 220. The edge of the eye-focusing area 220 near the second display area 320 is in contact with the edge of the second display area 320 near the eye-focusing area 220.
[0113] For example, please refer to Figure 4b , Figure 4b The diagram shows a cross-sectional view of a test and training system for vertical peripheral perception. The second display area 320 has line 420, and the first display area 310 has line 430. The peripheral vision of the subject's eyes perceiving line 420 is line 440. The peripheral vision of the subject's eyes perceiving line 430 is line 450. Since the center of the eye fixation area 220 and the subject's line of sight 410 for the first target object tend to be on the same horizontal line, and the first display area 310 and the second display area 320 are positioned adjacent to each other on both sides of the eye fixation area 220, the angle between line 440 and line 410 is equal to the angle between line 450 and line 410.
[0114] In this embodiment, the first display area and the second display area are positioned adjacent to each other on both sides of the eye's gaze area. This ensures that the two symmetrical positions in the first display area and the second display area are consistent with the relative positions of the subject's eyeballs, which facilitates subsequent evaluation of the subject and improves the accuracy of testing or training results.
[0115] In some implementations, please refer to Figure 5 The stimulus display area 230 is also used to display interfering visual information 510 during fixation, as simulated noise to attempt to influence the subject. For example, the interfering visual information can be used to simulate the real-world environment in which the subject performs the target task.
[0116] Interference visual information can be understood as display information designed to cause negative impacts by using visually misleading or confusing methods. Interference visual information can be an image in a specified scene, or a pattern generated by randomly lighting or turning off pixels in a stimulating display area.
[0117] In some cases, the real-world environment in which the subject performs the target task has a certain influence on the subject. For example, if a driver is driving a vehicle on the road, the road environment can distract the subject. Therefore, interfering visual information is displayed in the stimulus display area. Specifically, during the subject 250's fixation on the first target object 240, interfering visual information 510 and a second target object 260 are displayed in the stimulus display area 230. The second target object 260 is used to stimulate the subject 250 to provide visual feedback, while the interfering visual information 510 interferes with the subject's perception, in order to check whether the subject's peripheral vision in the vertical direction can eliminate interference and perceive the second target object 260.
[0118] In some implementations, interfering visual information is displayed continuously or intermittently in the stimulus display area in order to more realistically simulate the real environment in which the subject performs the target task and to gain a deeper understanding of the subject's vertical peripheral perception ability.
[0119] In some implementations, the visual interference information includes the real-world environment in which the subject performs the target task, and / or irregularly distributed points generated by randomly lighting up pixels in the stimulus display area.
[0120] In the above embodiments, by displaying visual interference information as simulated noise in the stimulus display area, an attempt is made to influence the subject, thereby improving the accuracy and reliability of the test or training results.
[0121] In some implementations, please refer to Figure 6 The display unit includes three independent display modules: a first display module 610, a second display module 620, and a third display module 630. The first display module 610 provides a first display area; the second display module 620 provides a second display area; and the third display module 630 provides an area for eye gaze.
[0122] Specifically, the vertical field of vision includes the angles above and below the standard line of sight. To accurately test or train the subject's vertical peripheral perception ability, the eye fixation area is set within the subject's central field of vision. Therefore, the third display module 630 is correspondingly set within the subject's central field of vision. The first and second display areas are respectively set within corresponding areas in the vertical direction of the peripheral field of vision. Thus, the first display module 610 and the second display module 620 are located on either side of the third display module 630, that is, the first display module 610 and the second display module 620 are located above and below each other in the vertical direction of the peripheral field of vision.
[0123] Understandably, the center of the third display module can be aligned with the subject's line of sight when looking at the first target object. The edge of the third display module near the first display module is positioned in contact with the edge of the first display module near the third display module. The edge of the third display module near the second display module is positioned in contact with the edge of the second display module near the third display module.
[0124] In this embodiment, the first display module 610, the second display module 620, and the third display module 630 may each have their own corresponding power supply circuit. The first display module 610, the second display module 620, and the third display module 630 may use a common power supply circuit, which may be mounted on a motherboard, integrated into any one of the first display module 610, the second display module 620, and the third display module 630. Furthermore, the first display module 610, the second display module 620, and the third display module 630 may each have their own corresponding processing module. The first display module 610, the second display module 620, and the third display module 630 may use a common processing module, which may be mounted on the motherboard along with the common power supply circuit. It is understood that the processing module may also be communicatively connected to a computer device.
[0125] In some implementations, please refer to [the relevant documentation]. Figure 6 The first, second, and third display modules each use a flat screen. Alternatively, please refer to... Figure 7 The third display module 630 uses a flat screen, while the first display module 610 and the second display module 620 use curved screens respectively.
[0126] In this embodiment, using flat screens for the first, second, and third display modules helps control costs. The third display module, which provides the eye fixation area, uses a flat screen, while the first and second display modules, which provide the stimulus display area, use curved screens. The curved structure ensures that the distance between the subject and each row of pixels on the curved screen is the same, thereby reducing the impact of the distance between the subject and each row of pixels on the test or training results.
[0127] In some implementations, the test training system also includes a ranging unit for determining whether the subject's head is within a specified area.
[0128] The ranging unit can employ an image acquisition unit incorporating deep learning algorithms. This unit creates a 3D model of the subject's head position and determines the range of head movement, i.e., the designated area. The ranging unit can also utilize an ultrasonic Time-of-Flight (TOF) module, which measures distance using the time of flight of ultrasonic pulses. Alternatively, a lidar module can be used, which scans the subject with a laser beam and receives reflected light signals, calculating the time difference to determine the distance between the subject and the lidar. An optical TOF module can also be used, employing an infrared light source to calculate the distance between the subject and the sensor by measuring the time difference of light propagation. Finally, a time-of-flight (TOF) module can be employed, using radio waves as the transmitted signal and measuring the time it takes for the radio waves to travel through the air to calculate the distance. It should be noted that if a lidar module is used, the ranging capability of the laser and its relatively small angle can be utilized to determine whether the subject's head is within the designated area.
[0129] Specifically, please refer to Figure 8a The ranging unit 810 can be mounted on the display unit 210. See also... Figure 8b The ranging unit 810 can also be separated from the display unit 210. For example, the relative positional relationship between the eye's gaze area and the stimulus display area, and the relative positional relationship between the eye's gaze area and the subject's head, can be determined. Based on these relative positional relationships, the installation position and angle of the ranging unit can be determined to accurately detect whether the subject's head is within a specified area. The specified area can be understood as limiting the range of motion of the subject's head to maintain the subject's head tending to remain still and the eyes tending to remain still in the vertical direction.
[0130] In some implementations, the ranging unit includes multiple ranging modules, each providing a signal coverage area. The defined area is determined based on the overlapping area of the signal coverage areas provided by each ranging module.
[0131] In this embodiment, the ranging unit may include two ranging modules, denoted as ranging module A and ranging module B. Ranging module A provides a signal coverage area A. Ranging module B provides a signal coverage area B. There is an overlapping area between signal coverage area A and signal coverage area B, which is defined as a specified area. If ranging module A and ranging module B simultaneously receive reflected signals, it can be determined that the subject's head is located within the specified area. If one or both ranging modules A and B do not receive reflected signals, it can be determined that the subject's head is not located within the specified area, and a reminder message can be issued to prompt the subject to move vertically to place the subject's head within the specified area. For example, if ranging module A is located below ranging module B, and if ranging module B does not receive a reflected signal but ranging module A does, the subject is prompted to move upwards vertically.
[0132] In this embodiment, the ranging unit may include two ranging modules, denoted as ranging module A1 and ranging module A2, and ranging module B1 and ranging module B2. These modules are installed vertically from top to bottom. Ranging module A1 provides a signal coverage area A1. Ranging module A2 provides a signal coverage area A2. Ranging module B1 provides a signal coverage area B1. Ranging module B2 provides a signal coverage area B2. The overlapping area of signal coverage areas A1, A2, B1, and B2 is defined as a specified area. If all four ranging modules simultaneously receive reflected signals, it can be determined that the subject's head is within this specified area. If at least one of the four ranging modules fails to receive a reflected signal, it can be determined that the subject's head is not within this specified area, and a warning message can be issued to prompt the subject to move vertically to place their head within the specified area. For example, if the ranging module A1 does not receive a reflected signal, but the ranging modules A2, B1, and B2 all receive a reflected signal, the subject is reminded to move downwards in the vertical direction.
[0133] In the above embodiments, by determining the specified area based on the overlapping area of the signal coverage provided by each ranging module, the location of the subject can be accurately determined, thereby reducing test errors and improving the accuracy of test or training results.
[0134] In some implementations, please refer to Figure 8cThe display unit 210 includes a first display module 610 and a second display module 620 for providing a stimulus display area. The first display module 610 and the second display module 620 are located on the upper and lower sides of the eye's gaze area, respectively. Two ranging modules are respectively provided on the first display module 610 and the second display module 620, and the two ranging modules on the first display module and the two ranging modules on the second display module are symmetrically arranged.
[0135] For details, please continue reading Figure 8c The first display module 610 and the second display module 620 are located on either side of the eye fixation area 220, for example, the first display module 610 is located above the eye fixation area 220, and the second display module 620 is located below the eye fixation area 220. The first display module 610 has two ranging modules, designated as the first ranging module 802 and the second ranging module 804. The second display module 620 has two ranging modules, designated as the third ranging module 806 and the fourth ranging module 808. The subject's standard line of sight can be on the same horizontal plane as the center line of the eye fixation area 220. To improve the controllability of the experiment and the generalizability of the results, the first ranging module 802 and the fourth ranging module 808 can be symmetrically arranged with respect to the center line of the eye fixation area 220, and the second ranging module 804 and the third ranging module 806 can be symmetrically arranged with respect to the center line of the eye fixation area 220.
[0136] In the above embodiments, two ranging modules are respectively provided on the first display module and the second display module, and the two ranging modules on the first display module and the two ranging modules on the second display module are symmetrically arranged, which can improve ranging accuracy, reduce errors and deviations, and improve the repeatability and reliability of the experiment.
[0137] In some implementations, the feedback unit uses at least one of a foot pedal and a button. The display unit uses an LED dot matrix screen.
[0138] Specifically, an LED dot matrix screen can be used to provide an eye-focused area and a stimulus display area. Subjects use their peripheral vision to perceive a second target object appearing vertically. Within a preset time period, subjects may or may not trigger a foot pedal, indicating whether they perceived the stimulus of the second target object within that time period. Similarly, subjects may or may not trigger a button within a preset time period, indicating whether they perceived the stimulus of the second target object within that time period.
[0139] This specification provides a method for testing and training vertical perimeter perception capabilities. Please refer to [link / reference needed]. Figure 9 The testing and training method for this vertical perimeter perception capability may include the following steps:
[0140] S910. Display the first target object in the eye fixation area to guide the subject to fixate on the first target object, and keep the subject's head and eyes relatively still in the vertical direction.
[0141] Specifically, since this study targets the subject's vertical peripheral perception ability, it is necessary to keep the subject's head and eyes relatively still in the vertical direction. Therefore, a first target object can be displayed at a designated location (e.g., the center) within the eye's gaze area to guide the subject's focus. While the subject is focusing on the first target object, their central visual field can be fixed at the designated location within the eye's gaze area to maintain head and eye movement as much as possible in the vertical direction.
[0142] S920. During the subject's fixation on the first target object, a second target object is displayed in the stimulus display area to stimulate the subject's perception of the second target object.
[0143] The eye-focusing area and the stimulus display area are distributed along the vertical direction.
[0144] Specifically, to test or train subjects' visual perception ability in the vertical direction, a second target object is displayed in the stimulus display area while the subject is fixating on a first target object. The second target object serves as a stimulus point to visually stimulate the subject, thereby checking whether the subject can perceive the second target object in the vertical direction using peripheral vision.
[0145] For example, a second target image is determined by stimulating pixels in the display area that are suddenly lit or turned off. The second target image is then used to stimulate the subject to perceive the image using peripheral vision in the vertical direction, in order to test or train the subject's vertical peripheral vision perception ability.
[0146] S930. Obtain the subject's perceptual feedback information on the second target object.
[0147] Among them, the perceptual feedback information and the location of the second target object are used to determine the vertical peripheral perceptual range of the subject.
[0148] Specifically, to promptly determine whether the subject has perceived a second target object appearing vertically using their peripheral vision, the testing and training system includes a feedback unit. When the subject perceives the second target object vertically using their peripheral vision, if the subject triggers the feedback unit within a preset time period, it indicates that the subject has perceived the stimulus of the second target object within that time period. The feedback unit responds to the subject's triggering action and acquires the subject's perceptual feedback information. If the subject does not trigger the feedback unit within the preset time period, it indicates that the subject has not perceived the stimulus of the second target object within that time period. The perceptual feedback information identifies the second target that triggered the subject's perception, and based on the second target that triggered the subject's perception and its location, the subject's vertical peripheral perception range can be determined.
[0149] In the above embodiments, a first target object is displayed in the eye fixation area to guide the subject to fixate on the first target object, while maintaining the subject's head and eyes in a vertically fixed position. During the subject's fixation on the first target object, a second target object is displayed in the stimulus display area to stimulate the subject's perception of the second target object, and the subject's perceptual feedback information on the second target object is obtained. Based on the perceptual feedback information and the location of the second target object, the subject's vertical peripheral perception range is determined, and the subject's visual perception ability in the vertical direction is evaluated, thus realizing a new method for testing and training vertical peripheral perception ability.
[0150] In some implementations, displaying a second target object in the stimulus display area may include: if the subject's head is detected to be within a specified range, and a set time for the stimulus to occur is reached, displaying the second target object in the stimulus display area.
[0151] In some cases, when the subject's head is within a specified range, it can be assumed that the subject's head tends to remain still and the eyeballs tend to remain still in the vertical direction. Therefore, the subject's head being within a specified range can be a prerequisite for testing vertical visual perception ability.
[0152] Specifically, the display rules for the second target object during the test are determined according to the test design and requirements. For example, multiple time points for the stimulus signal are pre-set to obtain the set time for the stimulus to appear, and the stimulus signal can only appear at the set time. The head position of the subject is determined by the ranging module. Based on the head position and the specified range, it is determined whether the subject's head is within the specified range. If the subject's head is detected to be within the specified range and the set time for the stimulus to appear has arrived, the second target object is displayed in the stimulus display area.
[0153] In the above embodiments, when the subject's head is detected to be within a specified range, if the set time for the stimulus to appear is reached, a second target object is displayed in the stimulus display area to stimulate the subject to perceive the second target object, thereby determining the subject's vertical peripheral perception range.
[0154] In some implementations, the method may further include displaying distracting visual information during gaze.
[0155] Interference visual information is displayed continuously or intermittently in the stimulus display area. Interference visual information includes the real-world environment simulating the subject's performance of the target task, and / or irregularly distributed points generated by randomly lighting pixels in the stimulus display area.
[0156] In some cases, noise during the testing process can have a certain impact on the subjects when they are performing the test task. Therefore, visually interfering information is displayed in the stimulus display area.
[0157] Specifically, during the test, the subject's gaze is focused on the first target object displayed in the gaze area, while the stimulus display area corresponding to the vertical peripheral task is located on the periphery and is easily affected by the surrounding environment. Therefore, during the subject's gaze on the first target object, interfering visual information and a second target object are displayed in the stimulus display area to interfere with the subject's perception, in order to examine whether the subject can perceive the second target object in the vertical direction despite the interference.
[0158] In the above embodiments, visual interference information is displayed during fixation, thereby improving the accuracy and reliability of testing or training results.
[0159] In some implementations, displaying a second target object in the stimulus display area includes displaying the second target object in the stimulus display area along a first direction away from the eye's gaze area.
[0160] Specifically, during the training test of vertical peripheral perception ability, the second target object can be displayed first in the stimulus display area closest to the eye's gaze area. If the subject perceives the stimulus of the second target object within a preset time period, the second target object is displayed in the stimulus display area corresponding to the first direction away from the eye's gaze area. This process is repeated, continuously displaying the second target object in the stimulus display area corresponding to the first direction away from the eye's gaze area, gradually increasing the viewing angle and distance to improve the subject's vertical peripheral perception ability, until the subject no longer perceives the stimulus of the second target object within the preset time period. At this point, it indicates that the location is outside the subject's vertical peripheral perception range.
[0161] In the above embodiment, a second target object is displayed in the stimulus display area along a first direction away from the eye's gaze area, and the position of the second target object gradually moves away from the eye's gaze area in order to accurately and efficiently test the subject's vertical peripheral perception range.
[0162] In some implementations, displaying a second target object in the stimulus display area includes displaying the second target object in the stimulus display area along a second direction close to the eye's gaze area.
[0163] Specifically, during the training test of vertical peripheral perception ability, the second target object can be initially displayed in the stimulus display area furthest from the eye's gaze area. If the subject does not perceive the stimulus of the second target object within a preset time period, the second target object is displayed in the stimulus display area corresponding to the second direction closer to the eye's gaze area. This process is repeated, continuously displaying the second target object in the stimulus display area corresponding to the second direction closer to the eye's gaze area, gradually decreasing the viewing angle and distance until the subject perceives the stimulus of the second target object within the preset time period. At this point, it indicates that the position has reached the maximum boundary of the subject's vertical peripheral perception range.
[0164] In the above embodiment, a second target object is displayed in the stimulus display area along a second direction close to the eye's gaze area, and the position of the second target object gradually moves closer to the eye's gaze area in order to accurately and efficiently test the subject's vertical peripheral perception range.
[0165] In some implementations, displaying a second target object in the stimulus display area includes randomly displaying a specified number of pixel rows in the stimulus display area as the second target object.
[0166] The specified number can be either 1 or 2, and its determination depends on the size of the stimulus display area. Specifically, a specified number of pixel rows are randomly displayed within the stimulus display area and used as the second target object. In each trial, perceptual feedback information is obtained based on whether the subject perceives the stimulus of the second target object. Furthermore, by statistically analyzing the obtained perceptual feedback information, the subject's vertical peripheral perceptual range can be determined.
[0167] In the above embodiments, a specified number of pixel rows are randomly displayed in the stimulus display area as a second target object, so as to provide visual stimulation to the subject in the vertical direction and collect the subject's perceptual feedback information on the second target object, so as to provide data support for subsequently determining the subject's vertical peripheral perception ability.
[0168] In some implementations, the method may further include: determining the location of the second target object in the next trial based on the perception feedback information of the current trial.
[0169] Specifically, in the current trial, a second target object appears. The subject perceives the second target object, and the perception of the subject is collected to obtain the perceptual feedback information for the current trial. This perceptual feedback information can reflect, to some extent, the subject's current vertical perceptual boundary. Therefore, to improve testing or training efficiency, the perceptual feedback information from the current trial can be used to analyze whether the subject perceives the second target object. Based on the analysis results of whether the second target object is perceived, the location of the second target object in the next trial is determined. For example, if the perceptual feedback information from the current trial indicates that the subject can accurately perceive the second target object, the range of its appearance needs to be expanded; if the perceptual feedback information from the current trial indicates that the subject cannot perceive the second target object, the range of its appearance needs to be narrowed.
[0170] In the above implementation, determining the location of the second target object in the next trial based on the perception feedback information of the current trial can reduce the randomness and randomness of the location of the second target object, thereby improving the efficiency of testing or training and better testing or training the vertical peripheral perception range of the subject.
[0171] In some implementations, determining the location of the second target object in the next trial based on the perceptual feedback information of the current trial includes: if the perceptual feedback information of the current trial indicates that the subject perceives the second target object, the location of the second target object in the next trial is moved along a first direction away from the eye's gaze area.
[0172] Specifically, if the feedback data at the current moment indicates that the subject can perceive the stimulus of the second target object within the preset time, it means that the location of the second target object is within the subject's vertical peripheral perception range. Therefore, in the next trial, the second target object will appear in the stimulation display area far away from the eye's gaze area, so as to increase the appearance range of the second target object and obtain more comprehensive perception feedback information from the subject.
[0173] In the above embodiments, if the perception feedback information of the current trial indicates that the subject perceives the second target object, the position of the second target object in the next trial moves along the first direction away from the eye's gaze area. This can reduce the randomness and randomness of the position of the second target object, thereby improving the efficiency of testing or training and better testing or training the subject's vertical peripheral perception range.
[0174] In some implementations, determining the location of the second target object in the next trial based on the perceptual feedback information of the current trial includes: if the perceptual feedback information of the current trial indicates that the subject did not perceive the second target object, the location of the second target object in the next trial is moved along a second direction closer to the eye's gaze area.
[0175] Specifically, if the feedback data at the current moment indicates that the subject did not perceive the stimulus of the second target object within the preset time, it means that the location of the second target object may have exceeded the subject's vertical peripheral perception range. Therefore, in the next trial, the second target object will appear in the stimulation display area close to the eye's gaze area to reduce the appearance range of the second target object, so as to obtain more comprehensive perceptual feedback information from the subject.
[0176] In the above embodiments, if the perception feedback information of the current trial indicates that the subject has not perceived the second target object, the position of the second target object in the next trial moves along the second direction close to the eye's gaze area. This can reduce the randomness and randomness of the position of the second target object, thereby improving the efficiency of testing or training and better testing or training the subject's vertical peripheral perception range.
[0177] In some implementations, obtaining the subject's perceptual feedback information on the second target object includes: collecting the subject's perceptual feedback information on the second target object when a response operation of the subject to the second target object is received.
[0178] Specifically, the subject uses peripheral vision to perceive a second target object appearing vertically. If the subject triggers the feedback unit within a preset time period, it indicates that the subject was able to perceive the stimulus of the second target object within the preset time period. If the subject does not trigger the feedback unit within the preset time period, it indicates that the subject did not perceive the stimulus of the second target object within the preset time period. Upon receiving the subject's response to the second target object, the feedback unit collects the subject's perceptual feedback information regarding the second target object.
