基于VRML的3D人—人交互界面的研究与实现

Research and Realization on the 3D Human-Human Interaction Interface Based on VRML

提出用 Ｖ Ｒ Ｍ Ｌ 技术实现 Ｃ Ｓ Ｃ Ｗ 系统中的３ Ｄ 人—人交互界面， 论述了基于 Ｖ Ｒ Ｍ Ｌ 的３ Ｄ 人—人交互界面的基本特性、实现方法及其通用性这种基于 Ｖ Ｒ Ｍ Ｌ 的３ Ｄ 人—人交互界面，较２ Ｄ 人—人交互界面，能为群体提供更丰富的协作信息，尤其是协作者身体活动的状态信息，使群体人员能更直观、更自然地交互；它实现了虚拟现实的效果，又可以不需要虚拟现实设备的支持，且与平台无关；它包含了２ Ｄ 界面和３ Ｄ 界面，两者可相互通信，协调工作，适用于需要集成２ Ｄ 和３ Ｄ 界面的 Ｃ Ｓ Ｃ Ｗ 系统，具有较广的通用性利用 Ｖ Ｒ Ｍ Ｌ 技术来构造 Ｃ Ｓ Ｃ Ｗ 系统中的３ Ｄ 人—人交互界。

The paper develops a new method to create 3D Human-Human Interaction Interface (HHII) in CSCW system by VRML technique and discusses the essential characteristics, realizing method and wide applicability of 3D HHII based on VRML . Compared with the 2D HHII, the VRML-based 3D HHII can provide a group with more information for cooperative work especially for collaborator's body language so that the cooperative group can interact more naturally and directly. The VRML-based 3D HHII,without support of the equipment for Virtual Reality (VR), can achieve the effect of VR and has no relationship with OS platform. The VRML-based 3D HHII consists of both 2D and 3D interface that can communicates and works in line, so it fits for the CSCW system that needs both 2D and 3D interface with wide applicability. Constructing 3D HHII by VRML technology can shorten the period of study and development greatly.
