面向普适环境的协同设计中,由于资源的不均衡和便携设备屏幕的限制,资源较少的站点无法以传统的协同感知方式实现感知信息交流。针对普适环境下感知方式的特点,文章提出离散系统神经网络的信息采集方式对动态多控制点感知信息进行自适应的屏蔽方法,提高了协同虚拟设计感知能力和工作效率。该技术已在CDUS原型系统中实现。 In the collaborative design for pervasive environment, due to the unbalance of resources and the limitations of portable devices’ screens, the sites with less resources can not realize the communication of perceptual information by the traditional cooperative sensing. In view of the characteristics of perceptual ways in universal environment, this paper proposes an adaptive shielding method based on the information collection method of discrete system neural network to the perceptual information of dynamic multi-control points to improve the perceived ability and work efficiency of collaborative virtual design. This technique has been implemented in the CDUS prototype system.
