摘要:

我们开发了一种新的握力测量概念,允许嵌入触觉刺激机制的抓手。该概念基于单个力传感器来测量施加在夹持器的每一侧上的力,并且它大大减少了由触觉器运动引起的力测量的伪影。为了测试这一新概念的可行性,我们建立了一个设备,测量控制的握力响应于触觉刺激从一个移动的触觉。首先,我们使用了一个定制设计的测试装置,其中有第二个力传感器,在0到20 N的范围内校准我们的设备,而不移动触觉器。其次,我们测试了触觉器运动对测得的握力的影响,并测量了1%测得的力的伪影。第三,我们证明了在动态变化的夹持力的应用中,平均误差为2.9%和3.7%的左右两侧的夹具,分别。最后,我们进行了一项用户研究,发现在对触觉运动的反应中,参与者增加了他们的握力,并且对于较小的目标力,增加的幅度更大,并且取决于触觉刺激的量。

英文摘要:

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.
