摘要:

空中触觉创造了一种新的反馈模式,让人们在空中感受触觉。超声波阵列聚焦空间中的声辐射压力,以从所产生的皮肤偏转诱导触觉感觉。在这项工作中,我们提出了一个低成本的触觉机器人测试半空中的触觉。通过将桌面机器人手臂与3D打印仿生触觉传感器相结合,我们开发了一种系统,可以感知,映射和可视化由超声换能器阵列创建的半空触觉。我们评估我们的触觉机器人通过测试它的各种半空中的触觉刺激,包括未调制和调制的焦点,创建一系列的触觉形状。我们将刺激的映射与另一种用于测试半空触觉的方法进行了比较:激光多普勒振动测量,突出了触觉机器人的优势,包括成本低得多,体积小,重量轻,易于使用。总的来说,这些研究结果表明,我们的方法对于感知半空中的触觉具有多种好处,并为扩展测试以更好地模拟人类触觉感知开辟了新的可能性。

英文摘要:

Mid-air haptics create a new mode of feedback to allow people to feel tactile sensations in the air. Ultrasonic arrays focus acoustic radiation pressure in space, to induce tactile sensation from the resulting skin deflection. In this work, we present a low-cost tactile robot to test mid-air haptics. By combining a desktop robot arm with a 3D-printed biomimetic tactile sensor, we developed a system that can sense, map, and visualize mid-air haptic sensations created by an ultrasonic transducer array. We evaluate our tactile robot by testing it on a variety of mid-air haptic stimuli, including unmodulated and modulated focal points that create a range of haptic shapes. We compare the mapping of the stimuli to another method used to test mid-air haptics: Laser Doppler Vibrometry, highlighting the advantages of the tactile robot including far lower cost, a small lightweight form-factor, and ease-of-use. Overall, these findings indicate our method has multiple benefits for sensing mid-air haptics and opens up new possibilities for expanding the testing to better emulate human haptic perception.
