Original description

VTT-ConIoT, a new publicly available dataset for the evaluation of HAR from inertial sensors in professional construction settings.The dataset contains data from 13 users and 16 different activities, collected from three differentwearable sensor locations.

The dataset contains also body/pose keypoints obtained from complementary video.

The dataset has been validated in a real construction site.
