This study investigates how controllability of force is influenced by concurrent vibrotactile feedback that is generated proportionally to the applied force. Three different models to provide tactile feedback are introduced: amplitude and frequency modulation and granular synthesis. Then, an experiment investigating the effect of the feedback models on force control is reported. The tactile feedback conditions were compared to each other and to a condition with no feedback in a force repetition and a force hold tasks. In the force repetition task, all the feedback conditions yielded significantly better accuracy compared to no feedback condition. In the force hold task, there was no difference in the accuracy between the conditions including the no feedback condition. The results suggest that dynamic vibrotactile feedback assists the force control in force repetition tasks.
本研究探讨了与施加力成比例产生的同步振动触觉反馈如何影响力的可控性。介绍了三种提供触觉反馈的不同模型：幅度和频率调制以及颗粒合成。然后，报告了一项研究反馈模型对力控制影响的实验。在力重复任务和力保持任务中，将触觉反馈条件相互比较，并与无反馈条件进行比较。在力重复任务中，与无反馈条件相比，所有反馈条件的准确性均显著提高。在力保持任务中，包括无反馈条件在内的各条件之间的准确性没有差异。结果表明，动态振动触觉反馈有助于力重复任务中的力控制。
