摘要
在对现有虚拟环境导航技术进行分析的基础上,针对单一导航方式难以同时胜任多种导航任务的问题,提出并实现了一种结合飞行的快速步行导航技术。该导航技术通过对用户交互意图和场景上下文的感知自动调整导航模式以适应不同类型导航任务的需求,从总体上提高了复杂虚拟环境下的导航效率。
Navigation in large and complex virtual worlds is a challenging interaction task that needs to meet various requirements. Most existing 3D navigation techniques usually only fit for some special virtual scenes. In order to improve adaptability and performance of navigation technique, a new 3D navigation technique, fast-speeding navigation combining walking with flying, is proposed. This technique automatically controls and switches modes and metaphors of navigation according to user's intentions and the context of virtual environment. Through seamless combination of flying and walking, the efficiency of navigation in complex virtual environments can be improved effectively.
