皮肤拉伸，当映射到关节位置时，使用类似于我们的本体感觉的机制提供触觉反馈。摇杆式皮肤拉伸装置通常在手臂的横向方向上致动，但是在肢体运动期间，围绕关节角度的拉伸是在纵向方向上。在本文中，人类的知觉性能在一个目标击中任务进行了比较两个方向的水稻触觉摇杆。由于生物学上的相似性，预期纵向方向更直观，从而产生更有效形式的触觉反馈。摇杆被放置在上臂上，并在五个垂直对齐的目标中传达光标的位置。与横向情况相比，纵向取向导致较小的误差。此外，对于纵向摇杆，达到外部目标的误差小于内部目标的误差。该结果表明，纵向拉伸比横向拉伸更容易辨别。
Skin stretch, when mapped to joint position, provides haptic feedback using a mechanism similar to our sense of proprioception . Rocker-type skin stretch devices typically actuate in the lateral direction of the arm, though during limb movement stretch about joint angles is in the longitudinal direction. In this paper, human perceptual performance in a target-hitting task is compared for two orientations of the Rice Haptic Rocker. The longitudinal direction is expected to be more intuitive due to the biological similarities, creating a more effective form of haptic feedback. The rockers are placed on the upper arm, and convey the position of a cursor among five vertically aligned targets. The longitudinal orientation results in smaller errors compared to the lateral case. Additionally, the outer targets were reached with less error than the inner targets for the longitudinal rocker. This result suggests longitudinal stretch is more easily discerned than laterally oriented stretch.
