The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the attention testing device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0050] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module and an attention test program.

[0051] exist Figure 1In the attention testing device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the attention testing device of the present invention can be set in the attention testing device, and the attention testing device calls the attention testing program stored in the memory 1005 through the processor 1001, and executes the attention testing method provided by the embodiment of the present invention.

[0052] Based on the above hardware structure, an embodiment of the attention testing method of the present invention is proposed.

[0053] Reference Figure 2 , Figure 2 It is a flowchart of a first embodiment of an attention testing method of the present invention.

[0054] In this embodiment, the attention test method includes the following steps:

[0055] Step S10: Determine whether the subject enters the formal test phase.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a mobile phone, a tablet computer, a personal computer, etc., or an electronic device or an attention testing device that can realize the above functions. The following takes the attention testing device as an example to illustrate this embodiment and the following embodiments.

[0057] Step S20: When the subject enters the test scene of the formal test phase through the wearable device, the test content presented by the wearable device is determined, and the subject's response to the target stimulus and non-target stimulus in the test content is output through the operating device.

[0058] It should be noted that wearable devices include VR headsets, and operating devices refer to VR operating handles.

[0059] It should be noted that the test scene is a VR virtual scene, which can be a virtual classroom scene. The virtual classroom scene is built based on the prototype of a general primary school classroom scene in reality. It mainly includes desk and chair models, desktop decoration models (including pencil cases and books), character models (including principals, teachers and children), blackboard models and projector screens, etc. These models are all made using 3Ds Max and designed and animated using Maya.

[0060] It should be noted that the test content can be a variation of CPT, which is derived from the CPT changing the reaction rules. Among them, CPT refers to the Continuous Performance Test (CPT) proposed by Conners et al. in 1985 and a series of related variations. For example, in the CPT method, the subjects will make corresponding reactions when seeing the target stimulus, and then the attention test of the subjects can be implemented based on these reactions. Specifically, taking the target stimulus as letter stimulation as an example, in the CPT method, the subjects need to press a key to react when seeing the letter X, and not react when seeing the other letters. In the formal testing phase of this program, the subjects need to press a key to react when the letter X appears immediately after seeing the letter A, and not react at other times.

[0061] It should be noted that the target stimulus and the non-target stimulus belong to the same type of stimulus. The target stimulus or the non-target stimulus can be stimuli such as letters, numbers, pictures and audios that appear in the test content.

[0062] In a specific implementation, the target stimulus is taken as a letter stimulus for illustration. In the test content, the subject needs to press a key to respond when the letter X appears immediately after the letter A, and not respond at other times. At this time, the letter X immediately following the letter A in the test content is the target stimulus, and the letter X that is not immediately following the letter A in the test content is the non-target stimulus.

[0063] In the specific implementation, taking the key response of pulling the trigger of the VR operating handle as an example, when the target stimulus appears in the test content, the subject needs to pull the trigger of the VR operating handle. When non-target stimulus or other letters appear in the test scene, the subject does not need to pull the trigger of the VR operating handle.

[0064] It should be noted that during the formal testing phase, the subjects need to maintain continuous attention, respond correctly to target stimuli, not respond to non-target stimuli, and avoid being affected by various other interfering stimuli.

[0065] In one embodiment, when the subject enters the test scene of the formal test phase through the wearable device, determining the test content presented by the wearable device, and outputting the subject's response to the target stimulus and non-target stimulus in the test content through the operating device, includes:

[0066] Acquiring a test presentation rule of the target stimulus and the non-target stimulus;

[0067] When the subject enters the test scene of the formal test phase through the wearable device, the test content is presented on the wearable device according to the test presentation rule, and the operation device outputs responses to target stimuli and non-target stimuli in the test content.

[0068] It should be noted that target stimuli are not limited to stimuli such as letters, words, numbers, and pictures. When presenting target stimuli in the test scenario, they can be presented according to the actual content of the text; the test presentation rules can include the presentation frequency and presentation time of target stimuli and non-target stimuli.

[0069] In the specific implementation, the target stimulus is taken as the letter stimulus for explanation, and the test presentation rules include the range of letters presented and the total number of letters presented. Specifically, the range of letters presented is A, B, C, D, E, F, G, H, J, L, X, and the total number of letters presented is 520. Among them, the frequency of appearance of the target stimulus (referring to the X that appears after A) is 10%, with a total of 52.

[0070] In the specific implementation, taking the test scene as a virtual classroom as an example, the test content will be presented on the whiteboard in front of the virtual classroom. When the target stimulus appears on the whiteboard, the subject needs to pull the trigger of the VR operating handle. When the non-target stimulus appears on the whiteboard, the subject does not need to pull the trigger of the operating device.

[0071] In one embodiment, when the subject enters the test scene of the formal test phase through the wearable device, determining the test content presented by the wearable device, and outputting the subject's response to the target stimulus and non-target stimulus in the test content through the operating device includes:

[0072] Obtain distractor presentation rules for distractor stimuli;

[0073] When the subject enters the test scene of the formal test phase through the wearable device, the test content and the interference content are presented on the wearable device according to the test presentation rules and the interference presentation rules, and the operation device outputs responses to the target stimuli, non-target stimuli in the test content and the interference stimuli in the interference content.

[0074] It should be noted that interference stimuli refer to stimuli that interfere with the subjects during attention tests; interference presentation rules are not limited to presentation frequency, presentation time, presentation interval time, and presentation space, etc.

[0075] It should be noted that interference stimuli will appear in the test scenes of the formal test phase in the form of various animations or audios. Taking the test scene as a virtual classroom as an example, interference stimuli refer to interference scenes that may appear in a normal classroom.

[0076] It should be noted that there are three types of interval time between two interference stimuli, namely 10 seconds, 15 seconds and 25 seconds, and each interval time appears three times in each interval; according to the presentation time of the interference stimuli, they can be divided into two types of interference stimuli, namely ordinary interference stimuli (duration is 5 seconds) and long interference stimuli (duration is more than 5 seconds). Specifically, ordinary interference stimuli include but are not limited to basketball sounds, bicycle bells, etc.; long interference stimuli include but are not limited to the principal passing by, the principal walking into the classroom, etc.

[0077] In the specific implementation, taking the test scene as a virtual classroom as an example, the spatial locations of all interference stimuli in the virtual classroom during the formal test phase are as follows: Figure 3 shown.

[0078] In this embodiment, since frequently presenting interference stimuli at the same spatial position of the test scene will cause the subject to feel irritated, the interference stimuli can be presented in the test scene according to the spatial position of each interference stimulus, which can avoid presenting different interference stimuli at the same spatial position of the test scene and affecting the subject's attention test results.

[0079] In one embodiment, the interference stimulus includes visual interference stimulus, auditory interference information and mixed interference stimulus; wherein obtaining the interference presentation rule of the interference stimulus includes:

[0080] Determining a test time for the formal test phase, and determining a plurality of preset intervals for the formal test phase according to the test time;

[0081] Interference presentation rules are determined based on visual interference stimuli, auditory interference stimuli and mixed interference stimuli randomly determined in each preset interval, wherein the frequency of appearance of the visual interference stimuli, auditory interference stimuli and mixed interference stimuli in each preset interval in the interference presentation rules remains consistent, and the order of appearance of the visual interference stimuli, auditory interference stimuli and mixed interference stimuli in each preset interval in the interference presentation rules is random.

[0082] In the specific implementation, the test time of the formal test phase is 13 minutes. The formal test phase can be divided into 4 preset intervals according to the test time. There is no interval between two adjacent preset intervals. The test time of each preset interval is 3.25 minutes. In the four preset intervals, the target stimulus and the non-target stimulus have the same frequency of occurrence and a random order of occurrence. At the same time, it is stipulated that when the last letter of the previous preset interval is A, the first letter of the next preset interval is not X.

[0083] In this embodiment, by setting visual interference stimulation and auditory interference stimulation, the subject can be interfered with in multiple aspects, thereby avoiding the influence of the subject's attention test result due to too single interference stimulation.

[0084] In one embodiment, presenting the test content and the interference content on the wearable device according to the test presentation rule and the interference presentation rule includes:

[0085] Determine the corresponding time points of the target stimulus sequence and the interference stimulus sequence;

[0086] Based on the corresponding time point, the test content and the interference content are presented on the wearable device according to the test presentation rule and the interference presentation rule.

[0087] It should be noted that the target stimulus sequence and the interference stimulus sequence are generated at the beginning of the formal test. Specifically, the presentation of the target stimulus in the test scene is to place a text box on the whiteboard of the virtual classroom, and present the target stimulus sequence in the text box according to the presentation rules. When presenting the target stimulus sequence, it is necessary to determine the timing of the appearance of each interference stimulus according to the interference stimulus sequence, and trigger the set program animation or audio file to play at the corresponding time point.

[0088] Step S30: Obtaining behavioral data, eye movement data, physiological characteristic data, and motion data of the subject after responding to target stimulation and non-target stimulation through the wearable device and the operating device.

[0089] It should be noted that behavioral data include but are not limited to accuracy, reaction time, etc., wherein the accuracy can be calculated based on the number of correct responses to the stimulus and the total number of stimuli to obtain the accuracy of the stimulus. Physiological characteristic data include electroencephalogram (EEG), electrooculogram (EOG), electrocardiogram (ECG) and skin conductance (GSR). Among them, EEG contains local field potentials of the cerebral cortex, which characterizes the comprehensive effect of synchronous electrical activity of neurons. EEG can be used to analyze frequency band power characteristics, waveforms, event-related potentials, coherence between brain regions, and phase synchronization, etc., and the waveforms have different frequencies and amplitudes, so that the waves can be divided into multiple types, for example, δ waves, θ waves, α waves, β waves and γ waves, and α waves are most significant when the subject is in a relaxed and awake state, and β waves appear when the subject's brain is in an active state. Therefore, the above EEG can be used to determine the subject's attention test results.

[0090] In addition, the subjects' blinking frequency, heart rate, and changes in skin sweating can be understood based on electrooculogram data, electrocardiogram data, and skin conductance data, which are related to stress. Eye movement data includes but is not limited to gaze point, blinking, and gaze duration.

[0091] It should be understood that different data can be collected through different devices. For example, eye movement data and motion data can be collected through VR headsets and VR operating handles in wearable devices, and physiological characteristic data can be collected through peripheral physiological sensors in wearable devices.

[0092] In the specific implementation, Figure 4 As shown, the sensor assembly in the peripheral physiological sensor can allow a wide range of head movements, wherein 57 electrodes are used to collect EEG, and 4 electrodes are used to collect EOG, specifically, an eye electrode set above the same eye and an eye electrode set below are used to measure vertical eye movement data, and an eye electrode set at the left temple and an eye electrode set at the right temple are used to measure horizontal eye movement data; 4 electrodes are used to collect ECG, and 2 electrodes are used to collect GSR, specifically, it is necessary to determine the non-dominant hand of the subject, for ordinary users, the non-dominant hand can be the left hand, and then before collecting, it is necessary to ensure that the first electrode is in close contact with the first finger of the non-dominant hand and the second electrode is in close contact with the second finger of the non-dominant hand, wherein the first electrode can be an Ag electrode, and the second electrode can be an AgCl electrode. In order to facilitate the collection of GSR, the first finger can be the index finger of the non-dominant hand, and the second finger can be the middle finger of the non-dominant hand, and then the GSR of the subject is collected using a conductivity device, which can be a conductivity meter.

[0093] It should be noted that at the beginning of the formal testing process, the current motion data of the subject is collected through the VR headset and operating equipment at a frequency of 50HZ, and the current motion data of the subject is not affected by non-target stimuli and interference stimuli when collecting the data.

[0094] It should be noted that during the formal testing phase, the collected data was read through Unity's built-in Transform component and written into a local csv file using the CsvHelper library. Two copies were made, one for upload, with the data stored in JSON format, and the other for detailed local storage.

[0095] In the specific implementation, during the formal testing phase, the collection process of different data is carried out asynchronously, and the recording process of different data is also carried out asynchronously. Each data collection takes from 1 / 100 second to 1 / 60 second.

[0096] Step S40: determining the attention test result of the subject according to the behavior data, eye movement data, physiological characteristic data and motion data.

[0097] It should be noted that after the subject's attention test is completed, the attention test results stored in the comma-delimited file are parsed into the memory, and then divided into blocks according to a fixed number of items (for example, 1,000 data items), and the data is sent to the designated server in blocks. During the sending process, breakpoint resumption is supported to facilitate subsequent analysis and viewing of the attention test results. Breakpoint resumption means that when data upload fails due to network reasons or user exits midway, uploading will continue from the interrupted data block.

[0098] This embodiment determines that the subject enters the formal test phase; when the subject enters the test scene of the formal test phase through the wearable device, determines the test content presented by the wearable device, and outputs the subject's response to the target stimulus and non-target stimulus in the test content through the operating device; obtains the behavioral data, eye movement data, physiological characteristic data and motion data of the subject's response to the target stimulus and non-target stimulus through the wearable device and the operating device; determines the subject's attention test result based on the behavioral data, eye movement data, physiological characteristic data and motion data. In the above manner, the traditional computerized CPT technology is adapted to the VR scene for attention testing, and the multimodal data of the subject's feedback on the attention test is collected more conveniently through VR technology, and finally the attention test result is comprehensively determined based on the multimodal data, thereby effectively improving the accuracy of the attention test result.

[0099] refer to Figure 5 , Figure 5 It is a flow chart of a second embodiment of an attention testing method of the present invention.

[0100] Based on the first embodiment, the attention test method of this embodiment further includes, before step S10:

[0101] Step S01: Determine whether the subject enters the practice phase.

[0102] It should be noted that before the subjects enter the practice phase, the operator needs to make the subjects wear a VR headset.

[0103] Step S02: When the subject enters the test scene of the practice phase through the wearable device, the test content presented by the wearable device is determined, and the reaction actions of the subject to the target stimulus and non-target stimulus in the test content are output through the operating device.

[0104] It should be noted that no interference stimuli are presented during the practice phase, and the presentation of target stimuli and non-target stimuli in the practice phase and the formal test phase is basically the same. The subjects' response actions to the target stimuli and non-target stimuli in the test content can be hitting actions, wrong hitting actions, or missed hitting actions.

[0105] Step S03: If the reaction actions performed multiple times in the practice phase are all hitting actions, it is determined that the subject enters the formal test phase.

[0106] It should be noted that the hitting action refers to the action of correctly pulling the trigger of the operating device and successfully hitting the object. In each practice, the number of target stimuli and non-target stimuli presented in the test content is the same. If the subject's response action is a wrong hit or a missed hit during the practice stage, a new round of practice will be entered. The subject can only enter the formal test stage if the response actions made during the practice stage or three consecutive practice stages contain wrong hits or missed hits.

[0107] This embodiment determines that the subject has entered the practice phase; when the subject enters the practice scene of the practice phase through the wearable device, determines the test content presented by the wearable device; outputs the subject's reaction actions to the target stimulus and non-target stimulus in the test content through the operating device; if the reaction actions made multiple times in the practice phase are all hitting actions, it is determined that the subject has entered the formal test phase. In this way, it can be ensured that the subject has understood the test rules of attention when entering the formal test phase, preventing the subject's attention test results from being affected by the subject's lack of understanding of the test rules of attention.

[0108] refer to Figure 6 , Figure 6 It is a flowchart diagram of a third embodiment of an attention testing method of the present invention.

[0109] Based on the above second embodiment, the attention test method of this embodiment further includes, before step S01:

[0110] Step S001: obtaining a valid test code through a main test subject, and after confirming the subject information of the valid test code through the main test subject, determining that the subject enters the animation guidance stage.

[0111] It should be noted that the main test subject can be the operator, who can start the attention test after generating a six-digit valid test code on the attention test device. The valid test code is a hexadecimal number generated by a pseudo-random method, which can be used by the bound subject for a single attention test and will become invalid after one use.

[0112] It should be noted that after obtaining a valid test code, the attention test device will display the subject information corresponding to the test code. After the operator confirms the subject information, the subject enters the animation guidance stage.

[0113] It should be noted that in the animation guidance stage, the practice stage, and the formal test stage, the target stimuli in the preset attention test mechanism test were all presented in the form of text components.

[0114] Step S002: When the target stimulus and the non-target stimulus are presented on the projector screen, the reaction action of the subject after being prompted by the simulated animation of the projector screen is obtained.

[0115] In the specific implementation, when entering the animation guidance stage, target stimuli and non-target stimuli will be presented on the projector screen. When the target stimulus appears, a simulated animation will appear below the target stimulus. The subject will make a certain reaction after seeing the simulated animation, that is, the reaction action made by the subject. After being prompted by the simulated animation on the projector screen, the reaction action made by the subject can be a hitting action, a wrong hitting action, or a missed hitting action.

[0116] Step S003: If the reaction actions made multiple times in the animation guidance stage are all hitting actions, it is determined that the subject enters the practice stage.

[0117] It should be noted that the specific number of times can be set in advance, for example, set to two times, that is, when the subject's reaction actions twice are both hitting actions, the subject will enter the practice stage.

[0118] In a specific implementation, a fixed sequence of letters will continuously appear on the projector screen: BED AX HFAH XC AX. Each fixed sequence of letters contains two target stimuli. When AX appears, a simulated animation is used to prompt the subject to pull the trigger of the operating device and shoot. The subject needs to correctly pull the trigger of the operating device and hit twice in total. When multiple reaction actions are all hitting actions, the animation guidance stage ends and the practice stage begins. Specifically, when the target stimulus appears, the font is red.

[0119] In this embodiment, after the subject obtains a valid test code through the main test subject and confirms the subject information of the valid test code through the main test subject, it is determined that the subject enters the animation guidance stage; when the target stimulus and non-target stimulus are presented on the projector screen, the reaction action made by the subject after being prompted by the simulated animation of the projector screen is obtained; if the reaction actions made multiple times in the animation guidance stage are all hitting actions, it is determined that the subject enters the practice stage.
