Abstract
This study investigates the effect of haptic control strategies on a subject's mental engagement during a fine motor handwriting rehabilitation task. The considered control strategies include an error-reduction (ER) and an error-augmentation (EA), which are tested on both dominant and non-dominant hand. A non-invasive brain-computer interface is used to monitor the electroencephalogram (EEG) activities of the subjects and evaluate the subject's mental engagement using the power of multiple frequency bands (theta, alpha, and beta). Statistical analysis of the effect of the control strategy on mental engagement revealed that the choice of the haptic control strategy has a significant effect (p < 0.001) on mental engagement depending on the type of hand (dominant or non-dominant). Among the evaluated strategies, EA is shown to be more mentally engaging when compared with the ER under the non-dominant hand.

这项研究研究了在精细运动手语康复任务中, haptic控制策略对Subject mental engagement的影响。被考虑的控制策略包括一个减少错误(ER)和一个增加错误(EA),这两种策略都在 dominant 和 non- dominant 手分别进行测试。一个非侵入性的脑机接口被用来监测Subject的EEG活动,并使用多个频率Band的能量评估Subject的 mental engagement。对控制策略对 mental engagement 的影响进行统计分析表明,根据手的类型( dominant 或 non- dominant),选择 haptic 控制策略具有显著影响(p < 0.001)。在评估的策略中,EA 在 non- dominant 手下比 ER 更具有心理 engagement。
