项目摘要

We proposed and made a prototype of a new force display device which is wearable. With the prototype, we examined technical requirement and solution when to integrate the system with IPT (Immersive Projection Technology).In terms of the proposal and prototype of a wearable force display, we proposed a guideline of the design and specified a means of quantitative analysis for its usability.We planned a mechanism of the device not to constrain user's mobility. Taking this plan into consideration, we realized the optimum interface for a user which is less constrained to carry so as to extend a user's working area especially around upper front of the body.Talking about the integration of the device with IPT, we developed software environment in order to synchronize visual and haptic display. In general, it is said haptic display requires high refreshing rate comparing to that of visual display for smooth communication. Therefore, visual and haptic display needs to be computed separately, but at the same time, share the model information.The concrete solution for the requirement, we proposed and installed the system called "haptic server." We verified the system is in well function to realize the visual and haptic environment to expand sensory display. We expect this environment will fit virtual cooperative work by many users. It is said sense of touch is effective to manage cooperative work.Therefore we applied the idea of haptic server to monopolize haptic information among remote places and realized virtual cooperative environment among remote places. We conducted several experiments and proved the efficiency of the environment for tele-cooperative work.

提出并制作了一种新型的可穿戴式力显示装置的样机。结合样机，研究了系统与IPT(沉浸式投影技术)集成的技术要求和解决方案；针对可穿戴式力显的方案和原型，提出了可穿戴式力显的设计指导思想和具体的可用性定量分析方法；规划了一种不限制用户移动的装置机制。考虑到这一方案，我们为用户实现了携带限制较少的最佳界面，从而扩展了用户的工作区域，特别是在身体的前部附近；谈到该设备与IPT的集成，我们开发了软件环境，以实现视觉和触觉显示的同步。一般来说，与视觉显示相比，为了顺畅地交流，触觉显示需要更高的刷新率。因此，视觉显示和触觉显示需要分开计算，但同时要共享模型信息。针对这一需求，我们提出并安装了一个名为“触觉服务器”的系统。验证了系统功能良好，实现了视觉和触觉环境下的扩展感官显示。我们希望该环境能够适应多个用户的虚拟协同工作。据说触觉是管理协同工作的有效手段，因此我们将触觉服务器的思想应用到远程位置间的触觉信息独占，实现了远程位置间的虚拟协作环境。我们进行了多次实验，证明了该远程协同工作环境的有效性。
