摘　　要：网络环境中的三维交互技术应用广泛,但目前存在数据量大和带宽有限的矛盾,无法满足交互的实时性要求。以用户兴趣和网络状态为出发点,在三维场景传输策略中引入上下文感知计算,实现系统对用户意图的自动感知和相关数据的预传输,充分利用网络的空闲带宽,达到缩短响应时间的目的,并在人体经络系统中的验证了传输策略的有效性。Interactive 3D techniques have been widely used in network environment,whereas they can not meet real time demands in human computer interaction because of the conflict between the large volumes of data and the limited network bandwidth.Taking user interest and network status as a starting point,context-aware computing is imported into transmission scheme or 3D scene into context-aware transport strategy,realizing user＇s intention awareness and relevant data prefetch.As the application of the human meridian system shows,the transmission strategy makes full use of the free bandwidth for shortening the response time.
