手势接口越来越多地集成在人机接口中，但它们通常依赖于视觉和听觉反馈，而忽略了触觉通道。随着在半空中提供触觉反馈的技术变得越来越成熟，研究它们的具体特性非常重要。在本文中，我们专注于指向手势和浮动显示器的组合，更精确地点击按钮。我们报告的用户研究的结果，详细调查通过超声换能器创建的反馈的不同参数。结果表明，当调制频率为150- 200 Hz时，反馈被认为是最合适的，这证实了对表面振动触觉刺激敏感性的研究结果。50或130 ms的信号持续时间没有显著影响。此外，我们提出了一个由词对组成的问卷，以评估触觉特征的主观感知，为未来的研究提供基础。
Gestural interfaces are increasingly integrated in human-machine interfaces, but they often rely on visual and auditory feedback and neglect the haptic channel. With technologies providing tactile feedback in midair becoming more mature, it is important to investigate their specific properties. In this paper, we focus on pointing gestures and the combination with floating displays, more precisely tapping buttons. We report the results of a user study investigating in detail different parameters of feedback created through ultrasonic transducers. The results show that the feedback is perceived as most suitable when a modulation frequency of about 150--200Hz is used, which confirms the findings on sensitivity for vibro-tactile stimuli on surfaces. The duration of the signal of either 50 or 130ms did not have a significant effect. Moreover, we present a questionnaire consisting of word pairs to rate the subjective perception of haptic characteristics, to provide a basis for future research.
