Demo of picoRing mouse: an ultra-low-powered wireless mouse ring with ring-to-wristband coil-based impedance sensing
中文摘要#
无线鼠标指环为可穿戴计算平台提供了微妙且可靠的指针交互，但微型指环中的小型电池低于 27 mAh，由于当前低功耗无线通信（如 BLE）的功耗，限制了指环的连续使用时间仅为 1-2 小时。 然而，picoRing 鼠标通过一种称为半主动电感遥测的基于线圈的阻抗感应方法，实现了超低功耗的指环到手环的无线通信，从而解决了这一问题。 这使得手环线圈可以通过敏感的电感耦合捕捉附近指环线圈的独特频率响应，并通过一个 820 uW 的鼠标驱动调制模块将用户的鼠标输入转换为独特的频率响应。 因此，picoRing 鼠标的连续使用时间在单次 20 mAh 电池充电的情况下，可以达到 92 小时以上，同时支持微妙的滚动和按压交互。
英文摘要#
Wireless mouse rings offer subtle, reliable pointing interactions for wearable computing platforms, but the small battery below 27 mAh in the miniature rings restricts the ring's continuous lifespan to just 1-2 hours due to the power consumption of current low-powered wireless communication like BLE. However, the picoRing mouse addresses this by enabling continuous ring-based mouse interaction with ultra-low-powered ring-to-wristband wireless communication through a coil-based impedance sensing method called semi-passive inductive telemetry. This allows a wristband coil to capture a unique frequency response of a nearby ring coil via sensitive inductive coupling, converting the user's mouse input into the unique frequency response via an 820 uW mouse-driven modulation module. Thus, the continuous use of picoRing mouse can potentially last over 92 hours on a single charge of a 20 mAh battery while supporting subtle scrolling and pressing interactions.
