The Copelabs/Usense Dataset

This dataset comprises experiments carried out with the open-source middleware NSense (fomerly named as USense), available at https://github.com/COPELABS-SITI/NSense. The data has been collected based on four sensors: bluetooth; Wi-Fi; microphone; accelerometer. NSense then relies on four different pipelines to compute aspects such as relative distance (Wi-Fi); social strength (based on bluetooth contact duration); sound activity level; motion. We set up experiments making use of Samsung Galaxy S3 devices. For each experiment, there is the following set of data files: - SocialProximity.dat has three columns: Timestamp, DeviceName, Encounter Duration, Average Encounter Duration, Social Strength (Per hour) and Social Strength(Per minute) towards DeviceName - DistanceOutput.dat has three columns: Timestamp, DeviceName, and Distance towards DeviceName - Microphone.dat has two columns: Timestamp, and Soundlevel(QUIET, NORMAL, ALERT and NOISY) - PhysicalActivity.dat has two columns: Timestamp, and Activity as STATIONARY, WALKING and RUNNING There are two tracesets. A first traceset has been collected relying on a first NSense version in 2015. Then, a second traceset has been collected in 2016, with a refined version of NSense. In all tracesets, devices have been carried around by people that share the same affiliation during their individual daily routines (24 hour periods).

本数据集包含基于开源中间件NSense（前身为USense）开展的实验数据，该中间件的开源获取地址为https://github.com/COPELABS-SITI/NSense。本次实验的数据采集依托四类传感器完成：蓝牙（Bluetooth）、Wi-Fi（Wi-Fi）、麦克风（Microphone）以及加速度计（accelerometer）。NSense依托四种不同的数据处理流水线，可计算相对距离（基于Wi-Fi信号）、社交亲密度（基于蓝牙接触时长）、声音活跃度以及运动状态。实验采用三星Galaxy S3设备开展。

每项实验均对应如下数据集文件：
- SocialProximity.dat：包含以下字段：时间戳、设备名称、接触时长、平均接触时长、每小时社交亲密度以及每分钟社交亲密度（针对目标设备）
- DistanceOutput.dat：包含以下字段：时间戳、设备名称以及与目标设备的相对距离
- Microphone.dat：包含以下字段：时间戳与声音等级，涵盖QUIET、NORMAL、ALERT与NOISY四个档位
- PhysicalActivity.dat：包含以下字段：时间戳与运动状态，涵盖STATIONARY（静止）、WALKING（行走）与RUNNING（奔跑）三类

本数据集包含两个追踪集：第一个追踪集于2015年基于初代NSense版本采集完成；第二个追踪集则于2016年依托优化后的NSense版本采集得到。所有追踪集的采集场景均为：参与者在每日日常活动周期（24小时时段）中随身携带设备，且所有参与者隶属于同一团体。
