本研究的目的是确定的效果，除了二进制振动触觉刺激的连续听觉反馈（元音合成）的人机界面（HMI）控制。16名健康参与者控制面部表面肌电图，以实现2-D目标（元音）。八名参与者仅使用实时听觉反馈来定位目标，而其他八名参与者则额外警告已实现目标，并在食指处进行确认性振动触觉刺激。所有参与者在三天的三次会议上使用他们指定的反馈方式（单独听觉或听觉和振动触觉相结合）进行训练，并在第三天使用新目标完成第四次会议以评估泛化。对1）达到目标的百分比和2）在目标上的试验时间百分比进行的方差分析揭示了反馈方式的主要影响：使用听觉和振动触觉反馈相结合的参与者比单独使用听觉反馈的参与者表现得更好。没有发现会话或反馈模态和会话的相互作用的影响，表明成功的推广到新的目标，但缺乏改进的培训课程。未来的研究是必要的，以确定在HMI控制过程中与听觉和振动触觉反馈相结合的认知成本。
The purpose of this study was to determine the effect of the addition of binary vibrotactile stimulation to continuous auditory feedback (vowel synthesis) for human-machine interface (HMI) control. Sixteen healthy participants controlled facial surface electromyography to achieve 2-D targets (vowels). Eight participants used only real-time auditory feedback to locate targets whereas the other eight participants were additionally alerted to having achieved targets with confirmatory vibrotactile stimulation at the index finger. All participants trained using their assigned feedback modality (auditory alone or combined auditory and vibrotactile) over three sessions on three days and completed a fourth session on the third day using novel targets to assess generalization. Analyses of variance performed on the 1) percentage of targets reached and 2) percentage of trial time at the target revealed a main effect for feedback modality: participants using combined auditory and vibrotactile feedback performed significantly better than those using auditory feedback alone. No effect was found for session or the interaction of feedback modality and session, indicating a successful generalization to novel targets but lack of improvement over training sessions. Future research is necessary to determine the cognitive cost associated with combined auditory and vibrotactile feedback during HMI control.
