| 摘 要： | 借鉴真实世界的认知心理学原理,将虚拟场景的可视表达和语义信息结合起来共同服务于用户的交互过程,多种3D交互技术被融合在一个统一的交互框架内,使复杂虚拟环境中的3D用户界面更容易被用户理解和使用.通过增强场景图的语义处理能力,建立支持高层语义的3D用户界面体系结构,3D交互系统不仅在几何层上而且还能在语义层上支持交互任务的执行.最后介绍了一个应用实例.

| Abstract: | Benefiting from the principles of cognitive psychology in the real world,we combine visual representation of virtual scene with their semantic information in VEs to support the user's interaction process.As a result,various types of 3D interaction techniques can be integrated into a consistent interaction framework,which makes 3D UIs more understandable and usable for users in complex VEs.By enhancing semantic-process ability of scene graph,we construct a special 3D interface architecture that supports high-level interaction semantics.Using this architecture,3D interactive systems can directly implement interaction tasks in geometric level and in semantic level.A VR application of guidance to touring in Children's Amusement City is presented. |
