Many input devices for computers have been proposed, keyboards are used for symbolic information and mice for two dimensional one.The effect of input in a virtual environment must be appealed to the sense organs because humans perceive the outside world from the five senses in real world.Important perceptual information while handling 3D objects is obtained from vision, haptic sensation, auditory sense, etc.The handling of three dimensional(3D) objects in a virtual environment requires an efficient input device which can handle these virtual objects as humans handle objects in real world.In this study, we proposed a 3D spatial interface device using strings, pulleys, and motors.The position of an operator's fingertip is measured by the lengths of the strings that are connected with a finger cap.The strings tensed by motors make force sensations.The operator can easily wear the cap, and move his/her fingers without restraint.We constructed a virtual environment for pick-and-place tasks with the device and 3D computer graphics.The operator could both see and feel the results of his/her hand motions in a very natural way.

人们已经提出了许多计算机输入设备，键盘用于符号信息，鼠标用于二维输入。由于人类从现实世界的五种感官感知外部世界，因此在虚拟环境中输入的效果必须引起感官的注意。处理三维对象时，重要的感知信息是从视觉、触觉、听觉等获得的。虚拟环境中的三维对象的处理需要一种高效的输入设备，它可以像处理现实世界中的对象一样处理这些虚拟对象。本文提出了一种使用弦、滑轮和鼠标的三维空间接口设备，该设备使用绳索、滑轮和鼠标来处理虚拟环境中的对象和马达。操作者的指尖位置是通过连接指帽的弦的长度来测量的。马达拉紧的弦产生力感。操作者可以很容易地戴上指帽，移动他/她的手指不受约束。我们利用该设备和3D计算机图形构建了一个虚拟的拾取放置任务环境。操作者可以非常自然地看到和感受他/她的手运动的结果。
