中文摘要： 人机交互触觉再现研究中，检测真实触觉与虚拟触觉的触觉神经兴奋状态，客观分析触觉刺激的电生理功效，一直是国内外研究机构感兴趣的课题。目前，人机交互领域的主要方法是根据使用者主观感觉调整触觉刺激，使虚拟触觉接近真实触觉。然而主观调整触觉刺激，不同时间和不同人体，主观感觉存在差异，这导致触觉再现缺乏普适性和实时性。即使采用微电极或探针刺入神经的检测方法，又会导致痛觉干扰触觉感觉。因此，本项目根据触觉诱发肌电变化的原理，采用皮肤表面阵列电极获取微弱的表面肌电，通过提取与触觉刺激和神经兴奋关联的表面肌电特征，间接获取触觉神经信号。再运用时频分析、统计模式识别、集成学习等方法，探索体表触觉刺激与触觉诱发表面肌电之间的的关联机理，构建基于触觉诱发表面肌电的触觉再现检测方法。本项目的预期成果，将为触觉再现的电生理检测提供体表检测技术和理论方法，为运用电生理学分析人机交互领域的触觉再现提供新的研究途径。

英文摘要： As for study of the tactile representation (TR) in the field of human-computer interaction (HCI), it is always an interesting research program of the domestic and foreign research institutions that detecting the real tactile (RT) and the virtual tactile (VT) in the firing state of antennal nerve, and objective analysing the electrophysiological effect of tactile stimulation (TS). At present, the primary method in the the field of HCI is adjustment of tactile stimulation close VT to RT according to the user's feeling to. However, there is the temporal difference and individual difference of tactile sense. Adjusting TS based on subjective feeling always makes TR lack of universality and real-time. Even using microelectrode or probe to penetrate into neural, the tradional detection method can cause pain interference with tactile sensation. Therefore, this project will base on the principle of the tactile evoked surface electromyography (eSEMG) to follow these steps: (1)use skin surface electrode array to get weak eSEMG; (2)extract eSEMG characteristics associated with tactile stimulation and neural excitation to indirectly obtain tactile neural signal; (3)use time-frequency analysis, statistical pattern recognition, ensemble learning method to explore the associated mechanism between the surface TS and subcortical
