This repository offers smart-home wearable accelerometer and Radio Signal Strength Indicator (RSSI) data acquired : 1) with low-cost hardware; 2) with high-resolution location annotations; 3) from four UK homes. The data are intended to evaluate RSSI-based indoor localisation methods with activity measurements provided from a user-worn wearable device. A wrist worn accelerometer records activity signatures which are relayed to a number of receiving Access Points (AP) placed throughout the building. Upon reception of a packet, each AP measures the RSSI of the received radio signal and timestamps the accelerometer measurements. Location labels are recorded automatically using a small camera which registers fiducial floor tags as the participant carries out their normal routines in a natural way. Approximately 14 h of annotated wearable measurements are provided. A scripted fingerprint measurement is provided along with several unscripted natural living recordings, where the participant carried out a number of daily household activities which are annotated, where possible, throughout. Codes are provided to access the data and to replicate the ground-truthing procedure.
本存储库提供智能家居可穿戴式加速度计和无线电信号强度指示 (RSSI) 数据:1)使用低成本硬件;2)具有高分辨率的位置注释;3)来自四个英国家庭。这些数据旨在评估基于 RSSI 的室内定位方法,并提供用户佩戴的可穿戴设备的活动测量结果。腕戴加速度计记录活动特征,这些特征被转发到建筑物内放置的多个接收接入点 (AP)。每个 AP 在接收到数据包时,都会测量接收到的无线电信号的 RSSI,并为加速度计测量结果加上时间戳。位置标签是使用小型摄像机自动记录的,当参与者以自然的方式进行正常日常活动时,摄像机会记录基准地板标签。大约提供了 14 小时带注释的可穿戴测量数据。提供了脚本化的指纹测量以及一些非脚本化的自然生活记录,其中参与者进行了多项日常家务活动,尽可能在整个活动中进行注释。提供了代码来访问数据并复制真实情况的处理过程。
