Can Be Worn More Than Collaborative Support Software System

Wearable Computing is a brand-new concept and computing mode fostered by the constant computer micromation and intelligentization with a"people-oriented"idea. In this century, with the rapid development of materials and computer technologies, wearable computers has been used in the military, industrial, aerospace, medical and other fields because of its wearable, environmental adaptability, and better human-computer interaction ability. However, as a new concept, wearable computing is still facing great difficulties. Especially in the software field, due to inherent weaknesses in limited hardware resources and the complex network environment, the traditional desktop computing software design patterns and support systems can not meet the needs of wearable computing.In view of the above problems, based on the remote collaborative applications of wearable computer in the enterprise field, we have proposed the establishment of wearable computer supported multiplayer collaborative soft system (WCSMCSS). In this paper, we have built the system framework and studied efficient collaborative technologies. The main contents and innovations can be summarized as follows: In order to satisfy the needs of WCSMCSS, the P2P (Peer-To-Peer) protocol and OSGi (Open-Services-Gateway-Initiative) technologies have been combined to design a software framework with characteristics of self-organization, modularity and extendable. Based on this framework, we have designed four layers software system, including presentation layer, service layer, middle layer and network layer.Based on the above software framework, we have studied its specific realization. Two kinds of display models (head mounted display and flat panel display) have been designed to build the presentation layer. Based on the remote collaborative applications (remote aware, remote attendance, remote communication, remote pointing, remote sensing and remote control), kinds of remote collaborative functions (online list of people, text chat, audio and video assistance, remote desktop assistance, whiteboard assistance) have been designed to build the service layer. Aim at enhancing system efficiency and saving system resources, the service manager, resource manager and event manager have been designed to build the middle layer. The network layer has been designed for the background of workshop network environment. According to the special requirements, we have proposed some optimize strategies, including dynamic services loading, aware services and services pre-fetching.According to the collaborative tasks demands for reliability and availability, we have designed the lab scene to simulate the workshop environment to assess the practical performance of the system. Through analyzing the experimental results, we have optimized the system design and refined key technologies.The experimental results show that this soft system can run better for remote collaboration, and have a good performance on the limited hardware resources. The whole software framework is reasonable and extensible. It's valuable to guide the design of wearable computer software system.
