Research On Multi-user Multi-device Interaction For Plan Seminar In Command Post

In the conditions of systems operations based on information systems,decision-making advantage plays a conclusive role in winning the war.Efficient running of plan seminar in command post guarantees the acquisition of decision-making advantage for command and control.Multi-user multi-device interaction system in command post,which has integrated new interactive devices and concepts,can contribute to the efficient operation of plan seminar.Therefore the research on multi-user multi-device interaction for plan seminar in command post is of great significance.The interactive nature of the command post is that the commanders use the interactive resources to complete the task of command and control.The user-resource-task ternary model is established,in which the user-resource matching and task-resource matching are two core issues.User-resource matching is multi-user multi-device interaction problem.The cognitive burden between users and devices has restricted the realization of multi-user mlti-device interaction,and the gesture channel is the most important source of user burden.Therefore,the multi-user mlti-device interaction on gesture modal is research focus.The task-resource matching is task analysis and matching algorithm.Task analysis can decompose the task into terminal interaction requirements.The matching algorithm between demand and equipment needs to study the interactive resource scheduling and the interaction requirement ordering.In addition,on the basis of the above research,the creative interactive mechanism to improve the opinion quantity and quality of plan seminar is also the content of this dissertation.This dissertation studies the multi-user and multi-device interaction problem for plan seminar in command post,including user-resource-task ternary model of command post,multi-user multi-device interaction on gesture channel,resource scheduling and demand sorting algorithm of multi-user multi-device interaction,creative interaction mechanisms for plan seminar.The innovations include:(1)Establishment of user-resource-task ternary model of command post.By analyzing the case description of the plan seminar,the three basic interactive elements of the command post were modeled and the ternary model was established.The interactive difficulties of the solution were analyzed,including cognitive burden between users and resources,and perception gap between tasks and resources,and the solving ideas were proposed.(2)The realization mechanism of multi-user multi-device interaction on gesture modal.We clarified the related concepts about interactive devices and gesture interaction,and built multi-user multi-device interaction model from three modules including input,output,and information processing.Four types of gesture interaction were extended at the physical layer,and auxiliary touchless interaction based on infrared image was proposed.Then we realized multi-user single-device interaction and single-user multi-device interaction.Gesture interaction system for multiple devices was realized based on universal gesture set.Multiple human collaboration system for multi-touch platform was implemented by means of territoriality-based pattern.(3)multi-person multi-device interaction algorithm.The solution to the cognitive gap between tasks and resources includes task decomposition and matching algorithms.There are two matching problems between interactive requirements and interactive devices,including interactive resource scheduling problem for interactive requirements,and interactive demand scheduling problem for interactive devices.Audio and vision are the main equipment output channels,while voice and gesture are the main user output channels.The research on voice channel has been relatively mature,so matching problems were modeled and solved on vision and gesture modal.(4)creative application mechanism of multi-person multi-device interaction.We analyzed experimentally the interaction difficulties in plan seminar,and then put forward the interaction model which combined the peripheral brainstorming rules with the internal creative thought stimulation method.Brainstorming interaction rules for plan seminar were designed according to the benefits and obstacles of brainstorming method;Opinion flow model for plan seminar task was established,and common creative thoughts were analyzed,and on the basis,creative thought incentive method based on task library and complex networks was proposed.The final output of brainstorming rules and creative thinking motivation method was terminal interaction requirements.Finally,the dissertation put forward the design and validation method for multiple systems usability contrast experiments,and practiced three kinds of intelligent command post in research project based on intelligent interaction model and mechanism theory for plan seminar in command post and verified the validity of the theory through usability experiment.
