TriadSense: body-worn and optical sensing of group activity in triads

TriadSense contains synchronised sensor recordings of nine groups of three people who assembled a puzzle together, with annotations of what every participant, every pair and the whole group did. Each participant wore an ear-worn device (OpenEarable 2.0) and a wrist-worn device (Xsens DOT); an optical motion-capture system (OptiTrack) recorded their positions. The record holds the raw recordings of the nine sessions, the annotations of three annotators (the final annotations, the original annotator's annotations before the review, and the reliability sample of 76 clips), the synchronised streams with the final labels on every sample, and the 5-second window table of the benchmark. Video and audio are not released. README.md describes every file and column. Access to the files requires accepting the terms of use (TERMS_OF_USE.md), which prohibit any attempt to re-identify the participants.
