在许多触觉训练系统中，用户需要佩戴手指保持器以便与系统交互并学习精细运动技能。众所周知，使用手指保持器的这种程序要求会降低用户指尖的力检测能力，从而可能导致学习效果不佳。为了增加用户的指尖力检测能力，一种可能的方式是使用随机共振（SR）。然而，SR对放置在手指保持器内的指尖的影响迄今为止是未知的。在本文中，首先，我们研究了当指尖被放置在手指保持器内时，SR对用户触觉性能的影响。然后，我们提出了一种新的触觉训练方法，利用触觉反馈和SR，以提高用户的性能结果。结果表明，即使当指尖被手指保持器包围时，用户指尖灵敏度也显著增加。我们执行了一个力学习任务，比较用户的性能在两个条件下：（i）触觉反馈SR（建议的方法），和（ii）触觉反馈没有SR。结果表明，用户的性能，通过任务的准确性，增加与建议的方法。这些研究结果表明，建议的触觉训练方法和SR在运动技能学习中的应用的有效性。
In many haptic training systems, the users need to wear a finger holder in order to interact with the system and learn fine motor skills. This procedural requirement of using a finger holder is known to decrease the user force-detection capability at the fingertip, which could lead to poor learning outcomes. In order to increase the fingertip force-detection capabilities of the user, one possible way is to use Stochastic Resonance (SR). However, the effects of SR on a fingertip placed inside a finger holder are hitherto unknown. In this paper, first we investigate the effects of SR on the user haptic performance when the fingertip is placed inside a finger holder. Then, we propose a new haptic training method that utilizes haptic feedback and SR to improves the user performance outcomes. The results show that the user fingertip sensitivity significantly increases even when the fingertip is enclosed by a finger holder. We performed a force learning task to compare the user performance under two conditions: (i) haptic feedback with SR (proposed method), and (ii) haptic feedback without SR. The results demonstrate that the user performance, measured through task accuracy, increases with the proposed method. These findings indicate the effectiveness of the proposed haptic training method and application of SR in motor-skill learning.
