在自由生活环境中对食物摄入和摄食行为的客观监测仍然是一个悬而未决的问题，对肥胖和进食障碍的研究和治疗具有重要意义。本文提出了一种新的可穿戴传感器系统（自动摄取监测器，AIM）的摄取行为在自由生活的客观监测。该设备集成了三种传感器模式，无线接口到智能手机：下颌运动传感器，手势传感器和加速度计。提出了一种新的传感器融合与模式识别方法，用于非主体性食物摄入识别。该设备和方法进行了验证，从12名受试者佩戴AIM在24小时的过程中，其中的日常活动和受试者的食物摄入量都没有以任何方式限制收集的数据。结果表明，该系统能够以89.8%的平均准确度检测食物摄入，这表明AIM可以用作监测自由生活个体的摄食行为的工具。
Objective monitoring of food intake and ingestive behavior in a free-living environment remains an open problem that has significant implications in study and treatment of obesity and eating disorders. In this paper, a novel wearable sensor system (automatic ingestion monitor, AIM) is presented for objective monitoring of ingestive behavior in free living. The proposed device integrates three sensor modalities that wirelessly interface to a smartphone: a jaw motion sensor, a hand gesture sensor, and an accelerometer. A novel sensor fusion and pattern recognition method was developed for subject-independent food intake recognition. The device and the methodology were validated with data collected from 12 subjects wearing AIM during the course of 24 h in which both the daily activities and the food intake of the subjects were not restricted in any way. Results showed that the system was able to detect food intake with an average accuracy of 89.8%, which suggests that AIM can potentially be used as an instrument to monitor ingestive behavior in free-living individuals.
