How do groups behave in VR? Monique Santoso coded 9,000 speech acts to develop Virtual Reality Interaction Dynamics Scheme, 10 speech acts (e.g., disagreements, context-dependent commentary). Prior speech acts and current nonverbal behavior predict group action. vhil.stanford.edu/publications...

Years went into the large-scale study that honed the cognitive load algorithm for HP Omnicept, measuring pupillometry, saccade, gaze direction, and heart-rate variability. 738 participants, 4 continents, ages 19-61, tasks varying in cognitive load. Now published! vhil.stanford.edu/publications...

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...
