As shown in Fig. 5 (a), the concrete methods of realizing of sensor model is as follows：By visualization means, propose to feel based on visual collaboration
Perception model, using a variety of information cognition modes suitable for collaborative perception.The cooperative awareness model, is defined as：VAM=O,
M, G, R, TA }, O represents perceptive object, includes the renewal of mission bit stream, the exchange of parameter information etc., usually by collaborator
What operation when carrying out task design triggered, thus it is related to collaborator information, it is equally also related to cotasking information；M generations
The form of expression or mapping mode of table perceptual model, i.e. perceptive object, mainly comprising graphic model；G represents awareness granularity, represents
The quantitative criteria that perceptive object matches with perceptual model, i.e., it is suitable one or more of for its matching according to the type of perceptive object
Perceptual model；R is sensing range, i.e., the spatial dimension that the map of perception can influence；TA is mission bit stream and the role of collaborator
Information.
Collaborative perception between multi-user mainly defines the interactive region of user by the rational perceptual strategy of application,
Realize the collaboration between user, the perception in cooperative surroundings between user refers to the cognitive ability to residing scene information, including
The renewal of shared object, text, the relevant information of voice and other users, by defining different sensing ranges, perception
Spend, different degrees of interaction between achievable user.The perceptual strategy controlled using multimodal user, is provided in perception
The method that a variety of users or shared object control its sensor model, first, user can pass through its position in holographic scene, side
To change in real time control it to perceive focus and mapping area accordingly；Secondly, focus and mapping area are perceived by setting
Parameter user is directly changed relevant feature parameters, and call in sensor model in real time；Finally, user's sensor model can root
Respective sensor model is called according to certain spatial areas in holographic scene.
Fig. 5 (b) illustrates Concurrency Control Algorithm flow.Con current control means mainly include locking method, affair mechanism, concentration
Control methods, rely on detection, reversible execution, master control entity etc..According to the characteristics of city planning design, using centralized Control method with
The method that token control method is combined, this method all provide a priority, main algorithm flow to the user for participating in collaboration
It is as follows：(1) a token is distributed to each shared resource；(2) if certain user needs to use certain shared resource, user chooses first
The shared resource, the token of the request application resource is sent from trend server；(3) server receives the application of user terminal；(4)
If now the resource is currently being used, refusal signal is sent, is otherwise gone to step (6)；(5) it is same if multiple user's applications be present
Individual resource, server then issue the token of the shared resource according to the priority of setting the user of highest priority, and to its
His user sends refusal signal, if race condition is not present, the token of the shared resource is just issued the applicant；(6) if with
Family obtains the token of a shared resource, then obtains to the operating rights of the shared resource, if receiving refusal signal, without pair
The operating rights of the shared resource；(7) any moment only has the token that a user possesses certain shared resource, and he is to the shared resource
Operation by server broadcast to other users, and it is occupied to identify the resource；(8) in each client, according to local
The operation of user and the copy operated to change the communal space in local from other people；(9) shared when user's use finishes this
After resource, the token discharged to the shared resource should be just reported to server.
