Rings are widely accepted wearables for gesture interaction. However, most rings can sense only the motion of one finger or the whole hand. We present PeriSense, a ring-shaped interaction device enabling multi-finger gesture interaction. Gestures of the finger wearing ring and its adjacent fingers are sensed by measuring capacitive proximity between electrodes and human skin. Our main contribution is the determination of PeriSense's interaction space involving the evaluation of capabilities and limitations. We introduce a prototype named PeriSense, analyze the sensor resolution at different distances, and evaluate finger gestures and unistroke gestures based on gesture sets allowing the determination of the strengths and limitations. We show that PeriSense is able to sense the change of conductive objects reliably up to 2.5 cm. Furthermore, we show that this capability enables different interaction techniques such as multi-finger gesture recognition or two-handed unistroke input.
环广泛被接受作为手势交互的可穿戴设备。然而，大多数戒指只能感知一个手指或整个手的运动。我们提出了 PeriSense，这是一种环形交互设备，能够实现多指手势交互。佩戴戒指的手指和相邻手指的手势通过测量电极和人体皮肤之间的电容接近度来感知。我们的主要贡献是确定 PeriSense 的交互空间，包括评估能力和限制。我们引入了一个名为 PeriSense 的原型，分析了不同距离下的传感器分辨率，并根据允许确定优势和限制的手势集评估手指手势和单笔画手势。我们表明，PeriSense 能够可靠地感知到 2.5 厘米范围内的导电物体的变化。此外，我们还表明，这种能力使不同的交互技术成为可能，如多指手势识别或双手单笔画输入。
