GelForce是一种新型的界面，可以测量力的大小和方向的分布。该传感器由透明弹性体、两层蓝、红标记和CCD摄像机组成。力矢量是从捕获的标记运动中计算出来的。力传感器的历史很悠久，但要获得力矢量的分布一直非常困难，因为几乎所有现有的传感技术都使用某种传感单元，其电阻或电容取决于力。对于旨在测量力矢量分布的这种类型的传感器，布线变得极其复杂，并且随着测量信息量的增加，单元的大小急剧膨胀。另一方面，我们开发的传感器的光学系统是简单的，因此各种应用是可能的，如机器人指尖的触觉，和一个通用的基于力的计算机接口。
GelForce is a novel type of interface that measures the distribution of both the magnitude and direction of force. The sensor is composed of a transparent elastic body, two layers of blue and red markers and a CCD camera. Force vectors are calculated from the captured movement of the markers.The history of the force sensor is ancient, yet it has always been exceedingly difficult to obtain the distribution of force vectors, because nearly all existing sensing technologies use some sort of sensing unit for which electric resistance or capacitance depends on force. For sensors of this type intended to measure the distribution of force vectors, the wiring becomes extremely complex, and the size of the unit expands dramatically as the amount of measured information is increased. On the other hand, the optical system of our developed sensor is simple, and various applications are therefore possible such as tactile sensation for a robotic fingertip, and a versatile force-based computer interface.
