本文研究的是力反馈手控器AirGlove的设计与实现。该设备使用在笛卡尔坐标系设置中排列的六个端口来对用户的手施加点力。压缩空气通过排气口排出，产生推力。合力的大小和方向是通过改变空气喷射的流量和通过激活不同的端口来控制的。AirGlove可以对用户的手施加任意点力。然而，这项研究的主要目的是向用户反映引力，以便能够产生虚拟对象的重量感觉。在介绍了气动手套的主要概念后，给出了该装置的设计和实现细节。接下来将解释AirGlove与名为VADE的虚拟装配系统的集成。最后，给出了利用该装置进行的实验细节并进行了讨论。结果表明，佩戴AirGlove的用户可以感觉到最小质量约为100克(~1N体重)，并且该设备可以创造出相当逼真的重量感觉。
: The research presented in this paper is the design and implementation of a force feedback hand master called AirGlove. The device uses six ports arranged in a Cartesian coordinate frame setting to apply a point force to the user's hand. Compressed air is exhausted through the ports, creating thrust forces. The magnitude and direction of the resultant force are controlled by changing the flow rate of the air jets and by activating different ports. The AirGlove can apply an arbitrary point force to the user's hand. However, the main goal of this research is to reflect gravitational forces to the user so that sensation of weight of a virtual object can be created. After introduction of the main concept of the AirGlove, the paper presents design and implementation details of the device. Integration of the AirGlove with a virtual assembly system called VADE is explained next. Finally, details of experiments with the device are presented and discussed. Results indicate that users wearing the AirGlove can feel a minimum mass of about 100 grams (~1N weight) and the device can create a fairly realistic weight sensation.
