触觉再现将人机交互模式由听觉+视觉发展到听觉+视觉+触觉三维融合的崭新阶段。静电力触觉再现具有真实感高、体验丰富和功耗低等优势，是在触摸屏上实现触觉再现最重要的方式。目前，以提升触觉真实感为目标的静电力触觉再现研究已取得显著进展，但为设计可用性强的触觉交互界面，加快其科学研究与商业化应用进程，需要解决触觉反馈对交互性能影响的有效度量与模型表征问题，现有以Fitts定律为代表的交互精度-效率模型通常依赖于视觉反馈，未考虑触觉反馈引入后交互真实感高。体验丰富等因素对交互性能的影响。为此，本项目基于课题组研制的静电力触觉再现设备，以核主成分分析和机器学习等为数学手段，研究不同静电力触觉驱动模式下交互精度和效率差异性的定量描述、静电力触觉反馈下交互精度-效率的理论建模、以及静电力触觉交互精度-效率模型的可信评测。为触觉交互界面设计及其开发标准研究提供理论依据，发展智能人机交互理论体系。

Tactile interaction promotes the development of the human-computer interaction mode from auditory + visual to auditory + visual + tactile in 3D fusion. Electrostatic tactile representation is the most important way on touch screen for its advantages of high reality, rich experience, low power consumption, and so on. At present, significant advances have been made in electrostatic tactile interaction with the sense of enhancing tactile reality. However, in order to design a highly-available tactile interface and accelerate its scientific research and commercialization application process, it is necessary to research the effect of tactile feedback on interaction performance from effective measurement and model representation issues. The existing accuracy-efficiency models, represented by Fitts law, depend on visual feedback, without considering the effect of high interaction reality and rich experience of electrostatic tactile feedback on user performance. Therefore, this project is based on the custom-designed electrostatic tactile display, exploits kernel principal components analysis and machine learning as mathematical means, researches the following three comments: 1) quantitative description methods of effect difference of electrostatic tactile excitation modes on interaction accuracy and efficiency, 2) theoretical modeling methods of interaction accuracy-efficiency under electrostatic tactile feedback, and 3) validation methods of the accuracy-efficiency model under electrostatic tactile feedback. This project will provide a theoretical basis for the design of tactile interface and the research on its standards, and develop the intelligent human-machine interaction theory system.
