New #cscw paper out with my amazing collaborators! In it, we predicted and analyzed what features saliently predicted turn-taking behaviors in VR 🗣️📢

Who speaks next? @PortiaWang.bsky.social analyzed a VR dataset of 77 sessions, 1660 minutes of group meetings over 4 weeks. Verbal & nonverbal history captured at millisecond level predicted turn-taking at nearly 30% over chance. To appear @acm-cscw.bsky.social. vhil.stanford.edu/publications...
