What can wearable sensors and usage of smart phones tell us about academic performance, self-reported sleep quality, stress and mental health condition? To answer this question, we collected extensive subjective and objective data using mobile phones, surveys, and wearable sensors worn day and night from 66 participants, for 30 days each, totaling 1,980 days of data. We analyzed daily and monthly behavioral and physiological patterns and identified factors that affect academic performance (GPA), Pittsburg Sleep Quality Index (PSQI) score, perceived stress scale (PSS), and mental health composite score (MCS) from SF-12, using these month-long data. We also examined how accurately the collected data classified the participants into groups of high/low GPA, good/poor sleep quality, high/low self-reported stress, high/low MCS using feature selection and machine learning techniques. We found associations among PSQI, PSS, MCS, and GPA and personality types. Classification accuracies using the objective data from wearable sensors and mobile phones ranged from 67-92%.
可穿戴传感器和智能手机的使用能告诉我们关于学业成绩、自我报告的睡眠质量、压力和心理健康状况的哪些信息呢?为了回答这个问题,我们使用手机、调查问卷以及参与者日夜佩戴的可穿戴传感器,从66名参与者那里收集了广泛的主观和客观数据,每位参与者的数据收集时长为30天,总计1980天的数据。我们分析了每日和每月的行为及生理模式,并利用这些长达一个月的数据,确定了影响学业成绩(平均绩点)、匹兹堡睡眠质量指数(PSQI)得分、感知压力量表(PSS)以及SF-12心理健康综合得分(MCS)的因素。我们还使用特征选择和机器学习技术,研究了所收集的数据将参与者准确分类为高/低平均绩点、良好/较差睡眠质量、高/低自我报告压力、高/低心理健康综合得分组的程度。我们发现了PSQI、PSS、MCS、平均绩点和性格类型之间的关联。使用来自可穿戴传感器和手机的客观数据进行分类的准确率在67%至92%之间。
