Abstract

We investigate the feasibility of a vibrotactile device that is both battery-free and electronic-free. Our approach leverages lasers as a wireless power transfer and haptic control mechanism, which can drive small actuators commonly used in AR/VR and mobile applications with DC or AC signals. To validate the feasibility of our method, we developed a proof-of-concept prototype that includes low-cost eccentric rotating mass (ERM) motors and linear resonant actuators (LRAs) connected to photovoltaic (PV) cells. This prototype enabled us to capture laser energy from any distance across a room and analyze the impact of critical parameters on the effectiveness of our approach. Through a user study, testing 16 different vibration patterns rendered using either a single motor or two motors, we demonstrate the effectiveness of our approach in generating vibration patterns of comparable quality to a baseline, which rendered the patterns using a signal generator.

激光驱动的振动触觉渲染
我们研究了一种无需电池和电子设备的振动触觉设备的可行性。我们的方法利用激光作为无线电力传输和触觉控制机制,它可以用直流或交流信号驱动 AR/VR 和移动应用中常用的小型致动器。为了验证我们方法的可行性,我们开发了一个概念验证原型,其中包括连接到光伏(PV)电池的低成本偏心旋转质量(ERM)电机和线性谐振致动器(LRA)。该原型使我们能够从房间的任何距离捕捉激光能量,并分析关键参数对我们方法有效性的影响。通过用户研究,测试使用单个电机或两个电机呈现的 16 种不同振动模式,我们证明了我们的方法在生成与使用信号发生器呈现模式的基线质量相当的振动模式方面的有效性。
