Hi, I would like to start extending BIDS to cover movement data, including live motion capture as well as virtual transform data. I have asked around on ResearchGate and a couple of other threads to see if there is ongoing work along the line and have not identified any yet- Here is the Google Doc for the proposal as a starting point. We would like to converge more opinions and contribution from anyone interested : https://docs.google.com/document/d/1iaaLKgWjK5pcISD1MVxHKexB3PZWfE2aAC5HF_pCZWo/edit?usp=sharing
