Sample Beiwe Dataset

This is a public release of Beiwe-generated data. The Beiwe Research Platform collects high-density data from a variety of smartphone sensors such as GPS, WiFi, Bluetooth, gyroscope, and accelerometer in addition to metadata from active surveys. A description of passive and active data streams, and a documentation concerning the use of Beiwe can be found here. This data was collected from an internal test study and is made available solely for educational purposes. It contains no identifying information; subject locations are de-identified using the noise GPS feature of Beiwe. As part of the internal test study, data from 6 participants were collected from the start of March 21, 2022 to the end of March 28, 2022. The local time zone of this study is Eastern Standard Time. Each participant was notified to complete a survey at 9am EST on Monday, Thursday, and Saturday of the study week. An additional survey was administered on Tuesday at 5:15pm EST. For each survey, subjects were asked to respond to the prompt "How much time (in hours) do you think you spent at home?".

本数据集为Beiwe生成数据的公开发布版本。Beiwe研究平台（Beiwe Research Platform）可从各类智能手机传感器采集高密度数据，涵盖全球定位系统（GPS）、无线局域网（WiFi）、蓝牙（Bluetooth）、陀螺仪（gyroscope）与加速度计（accelerometer），同时还可收集主动调研产生的元数据。有关被动与主动数据流的说明，以及Beiwe平台使用文档均可在此处查阅。本数据集源自一项内部测试研究，仅用于教育用途公开发布。该数据集未包含任何可识别身份的信息，研究对象的位置数据通过Beiwe的噪声GPS功能完成去标识化处理。作为本次内部测试研究的一部分，数据采集周期为2022年3月21日至2022年3月28日。本研究采用的本地时区为东部标准时间（EST）。每位研究对象会在研究周的周一、周四及周六的东部标准时间上午9时收到完成调研的通知。此外，研究对象还需在每周二的东部标准时间下午5时15分完成一项额外调研。每次调研中，研究对象均需回答如下问题：「你认为自己在家度过了多少小时？」
