The objective of this project is to develop a framework for anytime, anywhere collaborative virtual observation of events occurring in dynamic environments. The approach is to enhance recently developed virtual observation concepts by adapting software service composition mechanisms developed for pervasive computing systems. The observations, made at different points in time and space, are stitched together based on location, query, device, and other variables. Protocols for soft-real time delivery of data packets in heterogeneous networks comprising a combination of continuous and disruption tolerant communication channels are being developed. Middleware tools are being created to perform reactive and proactive query processing, matching, and synthesis of integrative panoramic views.The intellectual merit of the proposed work lies in the launching of the virtual observers, in retrospect, in soft real-time, on any device in a mobile environment and the concatenation of successive virtual observers to create virtual tours. Development of an integrated framework for video acquisition, stream processing, video synthesis, opportunistic networking, and integrated pervasive services in dynamic and heterogeneous environments are contributions of this project.With respect to broader impact, the research has the potential to provide new insights in the areas of video surveillance and security of public places. In general, outcomes of this project have broad applicability in such areas as science manufacturing, education, homeland defense, and entertainment. International collaboration with the Curtin University enables graduate students, including those from underrepresented groups, to interact with students and researchers in Australia, thus broadening their knowledge and skills.

这个项目的目标是开发一个框架，随时随地协作虚拟观察动态环境中发生的事件。 该方法是提高最近开发的虚拟观察的概念，适应软件服务组合机制开发的普适计算系统。 在时间和空间的不同点进行的观察基于位置、查询、设备和其他变量缝合在一起。 正在开发用于在包括连续和中断容忍通信信道的组合的异构网络中的数据分组的软实时递送的协议。 中间件工具正在创建执行反应和主动查询处理，匹配和综合的全景views.The智力的优点，所提出的工作在于推出的虚拟观察员，回顾过去，在软实时，在任何设备上的移动的环境和连续的虚拟观察员创建虚拟图尔斯的串联。 该项目的贡献之一是在动态和异构环境中开发一个视频采集、流处理、视频合成、机会网络和集成普适服务的集成框架，其影响更广泛，有可能为视频监控和公共场所安全领域提供新的见解。 总体而言，该项目的成果在科学制造、教育、国土防御和娱乐等领域具有广泛的适用性。 与科廷大学的国际合作使研究生，包括来自代表性不足群体的研究生，能够与澳大利亚的学生和研究人员互动，从而拓宽他们的知识和技能。
