超声波触觉反馈是一种很有前途的方法，可以在空中提供触觉，而不会妨碍用户使用致动器。然而，需要控制和严格的HCI研究来了解这种新反馈介质感知的基本特征，以及如何在界面中最好地利用超声波触觉。本文介绍了超声触觉感知的两个基本方面的两个实验：1)静态点的定位和2)运动的感知。了解这些将有助于我们了解1)超声波界面的空间分辨率，2)哪种反馈形式能产生最令人信服的运动错觉。结果表明，平均定位误差为8.5mm，沿纵轴方向误差较大。当行驶更长的距离时，使用更长的刺激持续时间和刺激轨迹上的多个点，就会产生令人信服的运动感觉。给出了反馈设计的指导原则。
Ultrasonic haptic feedback is a promising means of providing tactile sensations in mid-air without encumbering the user with an actuator. However, controlled and rigorous HCI research is needed to understand the basic characteristics of perception of this new feedback medium, and so how best to utilise ultrasonic haptics in an interface. This paper describes two experiments conducted into two fundamental aspects of ultrasonic haptic perception: 1) localisation of a static point and 2) the perception of motion. Understanding these would provide insight into 1) the spatial resolution of an ultrasonic interface and 2) what forms of feedback give the most convincing illusion of movement. Results show an average localisation error of 8.5mm, with higher error along the longitudinal axis. Convincing sensations of motion were produced when travelling longer distances, using longer stimulus durations and stimulating multiple points along the trajectory. Guidelines for feedback design are given.
