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. 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 hours of annotated wearable measurements are provided.
A user wears a wearable device on their wrist, which records accelerometer data at 25Hz. This data is transmitted, at 5Hz, towards a number of Bluetooth Low Energy access points (8-11) within the home. The access points mark the packets with a Received Signal Strength Indicator (RSSI) measurement and note the accelerometer measurements. The user's actual location is derived from a camera which registers fiducial floor tags, placed at a metre apart, where the user pose and relative position is decoded using image processing code (also provided).
