中文摘要:

      目的 完成假肢交互中振动反馈的设计方法，选择合适的振动反馈信号，为假肢反馈端的设计提供科学依据。方法 选择振动作为反馈信号，通过人机交互实验测量不同振动强度下人体的差别阈限，模拟截肢者在振动反馈下使用假肢完成任务的过程。结果 得出相应的用户数据并对其进行分析，在实验结果基础上提出假肢交互中振动反馈的设计方法。结论 振动对于人体是一种新的信号，截肢者可以通过训练逐渐掌握振动反馈，提升其对假肢产品的认同感，将假肢真正作为自己身体的一部分。以振动反馈的设计流程为例所提出的振动反馈的设计方法，为假肢产品反馈端的信号选择提供了包括用户灵敏度、人体对交互方式的适应期和用户的心理学数据等量化信息，提升截肢者对假肢产品的体验。

英文摘要:

      The work aims to complete the design of vibrotactile feedback in prosthetic interaction and select the proper vibrotactile feedback signal to provide scientific basis for the design of prosthesis feedback. Vibration was selected as the feedback signal. Through human-computer interaction experiment, the difference threshold of human body under different vibration intensities was measured, and the process of amputee using prosthesis to complete task under vibrotactile feedback was simulated. The corresponding user data were obtained and analyzed, and based on the experimental results, the design method of vibrotactile feedback in prosthetic interaction was put forward. Vibration is a new signal to the human body and amputee can gradually master vibrotactile feedback through training to improve the sense of identity with prosthetic product and regard prosthetic product as a part of body. With the design process of vibrotactile feedback as an example, the proposed design method of vibrotactile feedback provides quantitative information such as user sensitivity, adaptation period of human body to interaction mode and user's psychological data for signal selection at the feedback end of prosthetic product and improves amputee's experience of using prosthetic product.
