I believe in creating open datasets to contribute to research.

ContextAct @ A4H Dataset

A dataset of Activities of Daily Living containing 1 month of real-life data collected in a smart apartment with over 200 sensors. Download

Nurse Care Activity Recognition

Two datasets of wearable sensors and motion capture containing data about nurse care activities collected in a laboratory and real life settings (second challenge)

The first challenge Download

Data for the second challenge Download

Cooking activity Recognition

Contains data from 4 accelerometers (smartphones and smartwatches) and motion capture collected in a laboratory setting during cooking sessions of 3 recipes. Download
