在本文中，我们介绍了 HABits 项链的设计和实现，这是一种佩戴在脖子上的估计行为的设备。这种颈戴式设备不断发展，使研究人员能够在多种应用中使用它，包括饮食、手势和活动识别。我们提出的 HABits 项链使用三个嵌入式传感器（包括接近传感器、环境光传感器和 9 轴惯性测量单元 (IMU)）生成四个信号流。在这项工作中，我们强调了它描述饮食事件特征的能力。我们应用算法来估计咀嚼次数、喂食姿势的数量、姿势和活动强度。用户将能够在智能手机上实时直观地看到项链数据和算法结果。
In this paper, we present the design and implementation of the HABits necklace, a neck-worn device that estimates behavior. This neck-worn device is continuously evolving to provide researchers with the ability to use it in multiple applications including eating, gesture, and activity recognition. Our proposed HABits necklace generates four signal streams using three embedded sensors including a proximity sensor, ambient light sensor, and a 9-axis inertial measurement unit (IMU). In this work, we highlight its ability to characterize eating episodes. We apply algorithms to estimate chew count, number of feeding gestures, posture, and activity intensity. Users will be able to visually see the necklace data and the result of the algorithms on the smartphone in real time.
