触觉提示是智能眼镜的一种有价值的反馈机制。之前的工作已经表明，它们可以支持导航、发送通知和提示目标。然而，对机械手柄或风扇等驱动技术的关注限制了研究范围，仅限于在固定位置呈现的少量线索。为了超越这一限制，我们探索了空气中超声波触觉在面部的感知。我们提出了两项研究，考察了适合戴眼镜的三个面部部位的定位、持续时间和运动知觉的基本特性：脸颊、前额中心和眉毛上方。额头中心的定位误差为3.77 mm，持续时间(80%)和运动知觉(87%)准确。我们将这些发现应用于一项研究，该研究提供了八种不同的超声波通知，报告的平均识别率高达92.4%(峰值：98.6%)。最后，我们给出了面部超声波触觉提示的设计建议。
Haptic cues are a valuable feedback mechanism for smart glasses. Prior work has shown how they can support navigation, deliver notifications and cue targets. However, a focus on actuation technologies such as mechanical tactors or fans has restricted the scope of research to a small number of cues presented at fixed locations. To move beyond this limitation, we explore perception of in-air ultrasonic haptic cues on the face. We present two studies examining the fundamental properties of localization, duration and movement perception on three facial sites suitable for use with glasses: the cheek, the center of the forehead, and above the eyebrow. The center of the forehead led to optimal performance with a localization error of 3.77mm and accurate duration (80%) and movement perception (87%). We apply these findings in a study delivering eight different ultrasonic notifications and report mean recognition rates of up to 92.4% (peak: 98.6%). We close with design recommendations for ultrasonic haptic cues on the face.
