三维交互任务的描述和结构设计

主要讨论了三维交互中交互任务的归纳描述和结构设计问题.首先归纳出三维交互中的基本交互任务和普遍交互任务,对二者之间的联系进行了描述,提出了一个三维交互任务的产生框架,最终建立起三维交互中通用的核心模块.三维交互核心模块描述了三维交互中通用的底层结构,模块中定义了三维交互中通用的一系列交互原语和交互任务,实现了原语的产生和任务的整合工作.在开发三维用户界面构造系统(3D UI toolkit或3D UIMS)或具体的三维/虚拟现实应用时,可以直接用它来建立系统的底层交互结构,而程序员将只关注于交互风格的建立等高层工作.

Specification and Structure Design of 3D Interaction Tasks

This paper aims at 3D interaction task analysis and construction, summarizes interaction tasks in 3D interaction field, presents the integration process from basic interaction tasks to universal interaction tasks in 3D/VR application, and finally constructs a core toolkit which can be widely used in 3D interaction field. This core toolkit specifies the low level structure of 3D interaction. A set of interaction primitives, interaction tasks and the process about primitive creation and task integration are defined in it. It can be used as the low level platform in 3D UI toolkit, 3D UIMS or 3D/VR application development. Therefore programmer can just pay attention to the high level work such as interaction style construction.
