Haptic interaction between two humans, for example, a physiotherapist assisting a patient regaining the ability to grasp a cup, likely facilitates motor skill acquisition. Haptic human-human interaction has been shown to enhance individual performance improvement in a tracking task with a visuomotor rotation perturbation. These results are remarkable given that haptically assisting or guiding an individual rarely benefits their individual improvement when the assistance is removed. We, therefore, replicated a study that reported that haptic interaction between humans was beneficial for individual improvement for tracking a target in a visuomotor rotation perturbation. In addition, we tested the effect of more interaction time and a stronger haptic coupling between the partners on individual improvement in the same task. We found no benefits of haptic interaction on individual improvement compared to individuals who practised the task alone, independent of interaction time or interaction strength.
例如，在人类之间进行触觉交互，例如，理疗师协助患者恢复抓握杯子的能力，可能有助于运动技能的获得。触觉人际交互已被证明可以提高在具有视觉运动旋转干扰的跟踪任务中的个体表现。鉴于在去除辅助时，触觉辅助或引导个体很少有益于其个体改善，这些结果是显著的。因此，我们复制了一项研究，该研究报告称，在视觉运动旋转干扰中跟踪目标时，人类之间的触觉交互对个体改善是有益的。此外，我们测试了在相同任务中增加更多交互时间和增强合作伙伴之间的触觉耦合对个体改善的影响。与单独练习任务的个体相比，我们没有发现触觉交互对个体改善有任何好处，无论交互时间或交互强度如何。
