本文介绍了一种触觉虚拟环境，其中两个用户可以在通过互联网连接的不同物理位置协作雕刻虚拟粘土模型。他们以 3D 方式查看虚拟雕刻工具和粘土模型，感受工作时工具对粘土的压力，并将双手与工具和模型的视图放在同一位置。由于雕塑家对同一逻辑环境具有独立的视图，因此他们可以同时在不同的缩放级别和不同的坐标系中工作，甚至是旋转坐标系。这使他们能够探索新的协作创造力方式，并在适当的情况下发挥彼此的主动性。该系统的设计允许合作的雕塑家进行不受限制的异步行为。该论文描述了粘土表面变形背后的硬件和算法以及实现远程协作的通信模型。它解释了触觉反馈促进的简单冲突解决机制，并报告了对这种协作系统的创造力优势的定性研究结果。
This paper introduces a haptic virtual environment in which two users can collaboratively sculpt a virtual clay model, working from different physical locations connected by the internet. They view their virtual sculpting tools and the clay model in 3D, feel the tool’s pressure on the clay as they work, and have their hands co-located with the view of the tool and model. Since the sculptors have independent views of the same logical environment, they can work at different zoom levels, and be in different coordinate systems, even spinning ones, at the same time. This provides them with the capability to explore new styles of collaborative creativity, working off each other’s initiative where appropriate. The system was designed to allow unrestrained, asynchronous behaviour by the collaborating sculptors. The paper describes the hardware as well as the algorithms behind the deformability of the clay surface and the communications model enabling the distance collaboration. It gives an explanation of the simple conflict resolution mechanism that haptic feedback facilitates and also reports on the results of a qualitative study into the creativity benefits of such a collaborative system.
