Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, an implementation flow diagram of a method for determining concentration of a user according to an embodiment of the present invention is provided, where the method is applied to a VR device (e.g., a VR headset), and specifically includes the following steps:
s101, in a virtual reality-based business environment, a virtual reality space which a user should pay attention to is determined before business is carried out.
In a virtual reality-based business environment, a business initiator can specify a business participant, namely a virtual reality space which a user should pay attention to before a business is performed, and some business models which the user should pay attention to are included in the virtual reality space. Therefore, the service participant, namely the VR equipment worn by the user, can determine the virtual reality space which the user should pay attention to before the service is carried out in the virtual reality-based service environment.
Further, in a virtual reality-based business environment, a business initiator may specify a virtual reality space that a business participant, i.e., a user, should pay attention to before a business proceeds, and specify that the virtual reality space is marked in the form of a spherical marker. Thus, a service participant, i.e., a VR device worn by a user, can determine, in a virtual reality-based service environment, a virtual reality space that the user should be interested in before the service proceeds, and mark the virtual reality space in the form of a spherical marker.
It should be noted that the form of the spherical mark is simple, and other types of marks, such as a cube mark, may also be used, and the embodiment of the present invention does not limit this.
For example, in a virtual reality-based classroom environment, a virtual reality space in which a student should be focused is specified by a teacher before a classroom is performed, and the virtual reality space is specified to be marked in the form of a spherical marker, as shown in fig. 2, in which a teaching model (not shown in the figure) exists. Therefore, VR equipment worn by students can determine a virtual reality space which a user should pay attention to before a classroom is carried out in a virtual reality-based classroom environment, and mark the virtual reality space in a spherical mark mode.
It should be noted that, for a service, for example, a classroom may be used, for example, a service such as a conference may be used, a corresponding service environment, for example, a classroom environment may be used, for example, a service environment such as a conference environment may be used, and a corresponding service model, for example, a teaching model may be used, for example, a service model such as a conference model may be used, which is not limited in this embodiment of the present invention.
And S102, recording the visual focus space data of the user in the service process in real time in the service environment based on the virtual reality.
In a virtual reality-based service environment, a service participant, namely VR equipment worn by a user, can record visual focus space data of the user in a service process in real time.
For example, in a virtual reality-based classroom environment, VR devices worn by students can record visual focus spatial data of the students in the course of a classroom in real-time.
S103, determining the concentration degree of the user according to the intersection condition of the visual focus space data of the user and the virtual reality space.
For the visual focus space data of the user in the real-time recorded service process, the service participant, namely the VR device worn by the user, can determine the concentration degree of the user according to the intersection condition of the visual focus space data of the user and the virtual reality space which the user should pay attention to.
Wherein, for convenient definite user's concentration degree, carry out the in-process user's vision focus spatial data to the business of real-time recording, the business participant can be according to the crossing condition of user's vision focus spatial data and spherical mark, confirms user's concentration degree with the VR equipment of user wearing.
Specifically, as shown in fig. 3, for another implementation flow diagram of the method for determining the concentration degree of the user according to the embodiment of the present invention, the method is applied to a VR device (e.g., a VR headset), and specifically may include the following steps:
s301, determining a focus degree parameter corresponding to the visual focus space data of the user according to the intersection condition of the visual focus space data of the user and the spherical mark.
For the visual focus space data of the user in the real-time recorded service process, the service participant, namely the VR device worn by the user, can determine the attention parameter corresponding to the visual focus space data of the user according to the intersection condition of the visual focus space data of the user and the spherical mark.
Specifically, for the visual focus space data of the user during the service process recorded in real time, if the visual focus space data of the user and the spherical mark have an intersection, a service participant, that is, a VR device worn by the user, determines that the first attention parameter is the attention parameter corresponding to the visual focus space data of the user.
And for the visual focus space data of the user in the real-time recorded service process, if the intersection point does not exist between the visual focus space data of the user and the spherical mark, determining that the second attention parameter is the attention parameter corresponding to the visual focus space data of the user by a service participant, namely VR equipment worn by the user.
For example, for the visual focus space data of the student a during the classroom progression recorded in real time, if there is an intersection between the visual focus space data of the student a and the spherical marker, as shown in fig. 4, the VR device worn by the student a determines 1 as the attention parameter corresponding to the visual focus space data of the student a.
For example, for the visual focus space data of the student B during the classroom progression recorded in real time, if there is no intersection between the visual focus space data of the student B and the spherical marker, as shown in fig. 4, the VR device worn by the student B determines 0 as the attention parameter corresponding to the visual focus space data of the student B.
In addition, in the embodiment of the present invention, for the visual focus space data of the user during the service process recorded in real time, the service participant, that is, the VR device worn by the user, may determine the intersection condition of the visual focus space data of the user and the spherical mark according to a preset intersection determination period, and determine the attention parameter corresponding to the visual focus space data of the user according to the intersection condition of the visual focus space data of the user and the spherical mark.
For example, for the vision focus space data of the student a in the course of a classroom being recorded in real time, every 1 second of the VR device worn by the student a, the intersection condition of the vision focus space data of the student a and the spherical mark is determined, if the vision focus space data of the student a and the spherical mark have an intersection, 1 is determined as the attention parameter corresponding to the vision focus space data of the student a, and otherwise 0 is determined as the attention parameter corresponding to the vision focus space data of the student a.
It should be noted that, for the preset intersection determination period, for example, the interval may be 1 second, for example, the interval may be 0.5 second, and the like, which is not limited in this embodiment of the present invention. In addition, the first attention parameter and the second attention parameter may be set according to actual requirements, which is not limited in the embodiment of the present invention.
S302, determining the concentration degree of the user by using the attention degree parameter corresponding to the visual focus space data of the user.
For the visual focus space data of the user in the real-time recorded service process, the service participant, namely the VR device worn by the user, determines the attention degree parameter corresponding to the visual focus space data of the user according to a preset intersection determination period, and can determine the attention degree of the user based on the attention degree parameter, namely the attention degree parameter corresponding to the visual focus space data of the user is utilized to determine the attention degree of the user.
For example, for the vision focus spatial data of the student a during the classroom progression recorded in real time, the attention degree parameter corresponding to the vision focus spatial data of the student a is determined every 1 second by the VR device worn by the student a, as shown in table 1 below, so that the attention degree parameter corresponding to the vision focus spatial data of the student a can be utilized to determine the attention degree of the student a, that is, the classroom attention degree.
| Visual focus spatial data for student A | Attention parameter |
| Visual focus spatial data for student A at second 1 | 0 |
| Second student A's visual focus spatial data | 1 |
| Visual focus spatial data for student A at second 3 | 1 |
| …… | …… |
TABLE 1
It should be noted that, for the visual focus space data of the user during the service process recorded in real time, the service participant, that is, the VR device worn by the user, determines the attention parameter corresponding to the visual focus space data of the user according to the preset intersection determination period, which means that for the visual focus space data of the user in each intersection determination period, there is a corresponding attention parameter, as shown in table 1 above.
In addition, in order to reduce the amount of calculation and improve the efficiency of determining the concentration of the user, for the visual focus space data of the user in the real-time recorded service proceeding process, the service participant, i.e., the VR device worn by the user, may intercept the visual focus space data of the user in the target time period from the visual focus space data, so that the visual focus space data of the user in the target time period may be divided into the visual focus space data of the user in N time periods.
And searching a target attention parameter corresponding to the visual focus space data of the user in each time period from the attention parameters corresponding to the visual focus space data of the user in the real-time recorded service process, and determining the parameter number of the target attention parameter corresponding to the visual focus space data of the user in the target time period, so that the attention of the user is determined by using the target attention parameter and the parameter number.
For example, for the visual focus space data of student a during the classroom progression recorded in real time, the VR device worn by student a may intercept the visual focus space data of student a in pastN seconds from it, so that the visual focus space data of student a in pastN seconds may be divided into N1-second visual focus space data of student a, i.e., the 1 st, 2 nd, … …, N nd, etc. of student a in pastN seconds.
From the attention parameters corresponding to the visual focus space data of the user during the service progress recorded in real time, as shown in table 1 above, the target attention parameters corresponding to the visual focus space data of student a in each of the 1 st, 2 nd, … … th, nth, and so on in the past N seconds are searched, and the number of parameters of the target attention parameters corresponding to the visual focus space data of student a in the past N seconds is determined, so that the attention of the user can be determined by using the target attention parameters and the number of parameters.
For the number of parameters of the target attention degree parameter corresponding to the visual focus space data of the user in the target time period and the target attention degree parameter corresponding to the visual focus space data of the user in each time period, the VR device worn by a business participant, that is, the user, may input the target attention degree parameter and the number of parameters into the attention degree determination model, and obtain the attention degree of the user output by the attention degree determination model, where the attention degree determination model includes:
X＝Total[Average(X1，X2，……，XN)]/M；
the X comprises the user's concentration, the X1, X2, … …, XN each comprise the target concentration parameter, and the M comprises the number of parameters.
For example, for the parameter number M of the target attention degree parameter corresponding to the visual focus space data of student a in pastN seconds and the target attention degree parameter corresponding to the visual focus space data of student a in 1 st, 2 nd, … … th, nth seconds and the like in pastN seconds, the VR device worn by student a inputs the target attention degree parameter and the parameter number to the attention degree determination model, and acquires the attention degree of student a output by the attention degree determination model.
Note that X1 represents a target attention parameter corresponding to the visual focus space data of student a at the 1 st second of pastN seconds, X2 represents a target attention parameter corresponding to the visual focus space data of student a at the 2 nd second of pastN seconds, … … represents a target attention parameter corresponding to the visual focus space data of student a at the N th second of pastN seconds, XN.
In addition, different attention degree intervals are preset in the embodiment of the invention, and each attention degree interval has a corresponding attention degree grade. For example, different attention intervals are set in advance: concentration degree section 1, concentration degree section 2, concentration degree section 3, there is a corresponding concentration degree grade in each concentration degree section, as shown in table 2 below.
| Concentration interval | Concentration interval range | Concentration level |
| Concentration interval 1 | 90％～100％ | Is excellent in |
| Concentration degree interval 2 | 60％～90％ | Qualified |
| Concentration degree interval 3 | 0％～60％ | Fail to be qualified |
TABLE 2
For the concentration degree of the user, the service participant, namely the VR equipment worn by the user, can search the concentration degree interval corresponding to the concentration degree, and determine the target concentration degree grade corresponding to the concentration degree interval as the concentration degree grade of the user. For example, for the 92% concentration degree of student a, the VR device worn by student a can search for the concentration degree interval (concentration degree interval 1) corresponding to the concentration degree, and can determine the concentration degree grade (excellence) of student a.
To the degree of concentration level of user, the VR equipment that the business participant was worn by the user can be sent to the high in the clouds with it, so that the degree of concentration level of the user that corresponds can be sent to the high in the clouds with the VR equipment that a plurality of business participants were worn by the user, the high in the clouds is according to the degree of concentration level of the user, and the user quantity that each degree of concentration level corresponds is counted to according to the user quantity that each degree of concentration level corresponds, the quality of aassessment business.
For example, the VR device worn by student 1 sends the concentration level of student 1 to the cloud, the VR device worn by student 2 sends the concentration level of student 2 to the cloud, … …, and the VR device worn by student N sends the concentration level of student N to the cloud, as shown in fig. 5, so that the cloud can count the number of students corresponding to each concentration level according to the concentration level of each student, as shown in table 3 below, so that the quality of the classroom can be evaluated according to the number of users corresponding to each concentration level.
| Concentration level | Number of students |
| Is excellent in | 30 |
| Qualified | 3 |
| Fail to be qualified | 2 |
TABLE 3
It should be noted that, for the concentration level (excellent), the number of students is higher, which indicates that the classroom quality is higher, and indirectly indicates that the classroom of the teacher is more popular with the students.
