摘要

我们提出了AuraRing，一个可穿戴的电磁跟踪系统，用于细粒度的手指运动。硬件包括一个带有嵌入式电磁发射器线圈的戒指和一个带有多个传感器线圈的腕带。通过测量手腕周围不同位置的磁场，AuraRing估算出手指的五个自由度。AuraRing仅在模拟数据上进行训练，不需要运行时监督训练，从而确保了用户和会话的独立性。AuraRing的分辨率为0.1 mm，动态精度为4.4 mm，通过光学地面真实度用户评估测量。这个环是完全独立的，只消耗2.3兆瓦的能量。

Demo of AuraRing: Precise Electromagnetic Finger Tracking

We present AuraRing, a wearable electromagnetic tracking system for fine-grained finger movement. The hardware consists of a ring with an embedded electromagnetic transmitter coil and a wristband with multiple sensor coils. By measuring the magnetic fields at different points around the wrist, AuraRing estimates the five degree-of-freedom pose of the finger. AuraRing is trained only on simulated data and requires no runtime supervised training, ensuring user and session independence. AuraRing has a resolution of 0.1 mm and a dynamic accuracy of 4.4 mm, as measured through a user evaluation with optical ground truth. The ring is completely self-contained and consumes just 2.3 mW of power.
