Demo of picoRing mouse: an ultra-low-powered wireless mouse ring with ring-to-wristband coil-based impedance sensing
中文摘要#
無線鼠標指環為可穿戴計算平台提供了微妙且可靠的指針交互，但微型指環中的小型電池低於 27 mAh，由於當前低功耗無線通信（如 BLE）的功耗，限制了指環的連續使用時間僅為 1-2 小時。 然而，picoRing 鼠標通過一種稱為半主動電感遙測的基於線圈的阻抗感應方法，實現了超低功耗的指環到手環的無線通信，從而解決了這一問題。 這使得手環線圈可以通過敏感的電感耦合捕捉附近指環線圈的獨特頻率響應，並通過一個 820 uW 的鼠標驅動調製模塊將用戶的鼠標輸入轉換為獨特的頻率響應。 因此，picoRing 鼠標的連續使用時間在單次 20 mAh 電池充電的情況下，可以達到 92 小時以上，同時支持微妙的滾動和按壓交互。
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.
