该论文提出了一种基于声音分析的可穿戴用户活动识别设备的原型。它专注于适合小型化实施的低功耗实现。我们描述了识别性能和计算复杂度之间的权衡分析。此外，我们还介绍了硬件原型及其识别性能的实验评估。这包括逐帧识别、连续数据流中的事件检测以及背景噪声的影响。
The paper presents a prototype of a wearable, sound-analysis based, user activity recognition device. It focuses on low-power realization suitable for a miniaturized implementation. We describe a tradeoff analysis between recognition performance and computation complexity. Furthermore, we present the hardware prototype and the experimental evaluation of its recognition performance. This includes frame by frame recognition, event detection in a continuous data stream and the influence of background noise.
