  • 摘要:

    触摸屏上的触觉再现技术增加了人机交互的真实感和丰富性。在触觉再现中,掩蔽效应改变了触觉感知特性(绝对阈值和分辨阈值),影响了触觉渲染模型的准确性及触觉再现效果的真实性。基于机械振动、空气压膜与静电力三元融合的触觉再现装置,采用“三下一上”的实验方法,研究5种不同幅度的机械振动触觉反馈作为掩蔽刺激时,空气压膜触觉反馈感知特性的变化。与静电力触觉反馈作为目标刺激时感知特性的变化进行比较,得出如下结论:在绝对阈值方面,当机械振动驱动电压幅度由0 V增加到100 V时,空气压膜绝对阈值由34.30 V增加到46.41 V,增加了35.31%,增长幅度为静电力绝对阈值增长幅度的14.95%;在分辨阈值方面,当机械振动驱动电压幅度由0 V增加到100 V时,空气压膜分辨阈值在(15.21±0.67)V范围内浮动,变化趋势与静电力触觉反馈基本相同。
