面向任务的空基信息系统用户化人机交互设计

Design of task-oriented customized human-computer interaction for air-based information system

根据任务目标要求和执行过程,用户化定制空基信息系统人机交互界面和操作流程,使得系统人机交互功能更贴近于用户业务需求,更有效地协助用户实现其任务目标。具体方法是,以任务执行过程为主线,按照信息的获取、加工、存储、应用、分发等处理流程将任务分解为多个子任务,并以此为参照,将空基信息系统细化分解为多个子系统,然后根据各个子系统的操作要求定义系统操作员席位职责。一方面,面向任务目标要求和执行过程的系统功能分解方法确保了用户需求的落实;另一方面,多用户并行处理模式简化了用户操作视图,增强了系统的易用性和人机交互效率。该方法不仅可以在新系统研制过程中发挥良好作用,还可以在已有系统改造项目中得以应用。

According to the objective requirement and execution process of the task,the customized human-computer interaction interface and operation process of the air-based information system can make the human-computer interaction function more satisfactory to the customers’business needs and more effective for helping customers to finish their mission. Setting the execution process of the task as baseline,the task is disassembled to few subtasks based on the processing flow of information capture,handling,storage,application,distribution. As a reference,the air-based information system is disassembled to several subsystems,and then operator duty is defined according to the operation requirement of every subsystem. On one hand,the method that faces to the objective requirement and executing process of the task can ensure the realization of user’s requirements. On another hand,the parallel processing mode of multi-user simplifies the operation view,and enhances the usability and human-computer interaction efficiency of system. The method can be used not only in development of new systems,but also in reconstruction of the existing systems.
