论文摘要
我们开发了一种新的握力测量概念，该概念允许将触觉刺激机制嵌入抓手中。该概念基于单个力传感器，以测量施加在抓地力的每一侧的力，并且大大降低了由触电运动引起的力测量的伪像。为了测试这个新概念的可行性，我们构建了一种设备，该设备可根据移动触觉者的触觉刺激来衡量控制力的控制。首先，我们使用了带有第二个力传感器的自定义设计的测试设置来校准我们的设备在0到20 N的范围内，而无需移动触觉者。其次，我们测试了触电运动对测得的握力的影响，并测量了测量力的1％的伪影。第三，我们证明了在施加动态变化的抓地力时，握把的左侧和右侧的平均误差分别为2.9％和3.7％。最后，我们进行了一项用户研究，发现在响应于触电运动的情况下，参与者增加了握力，并且对于较小的目标力量而言，增加的抓地力较大，并取决于触觉刺激的量。
We developed a new grip force measurement concept that allows for embedding tactile stimulation mechanisms in a gripper. This concept is based on a single force sensor to measure the force applied on each side of the gripper, and it substantially reduces artifacts of force measurement caused by tactor motion. To test the feasibility of this new concept, we built a device that measures control of grip force in response to a tactile stimulation from a moving tactor. First, we used a custom designed testing setup with a second force sensor to calibrate our device over a range of 0 to 20 N without movement of the tactors. Second, we tested the effect of tactor movement on the measured grip force and measured artifacts of 1% of the measured force. Third, we demonstrated that during the application of dynamically changing grip forces, the average errors were 2.9% and 3.7% for the left and right sides of the gripper, respectively. Finally, we conducted a user study and found that in response to tactor movement, participants increased their grip force, and that the increase was larger for a smaller target force and depended on the amount of tactile stimulation.
