Reality Splits: Seeing Different Worlds in Mixed Reality | Psychology Today www.psychologytoday.com/us/blog/vrtu...
What if each of us saw a different reality? From personalization to artefacts, immersive technology is already taking us there, where no two users share the same visual reality.
Our new study investigates this perceptual conflict in collaborative MR @stanfordvr.bsky.social @ufresearch.bsky.social
Mixed reality promises shared digital spaces. But what if collaborators see different worlds? New research reveals how even small perceptual mismatches may reshape interaction.
📢New Pub📢 led by @portiawang.bsky.social (soon out in #CSCW2025 ) investigates turn-taking behaviors in social #VR by extracting features based on social dynamics literature 🗣️
Not all cues in immersive virtual environments are consistent with physical-world expectations, but can be transformed, resulting in different perceiv…
New paper out! We explore avatar embodiment experiences of 52 Black users in social VR from ethnographic interviews + lab study. Findings unpack embodied consequences of racial representation in immersive VR and how users navigated challenges to expressing identity. vhil.stanford.edu/publications...

5 robust, replicated, & meta-analyzed findings from 30 years of psych research in VR. Timeline of events in experiment history, recommendations for consumers & scholars new to the medium, and the DICE model on when to use (and not use) VR.

Augmented Reality eliminates "perceptual common ground".
What happens when 2 people see very different versions of the world around them?
New study by @eugyhan.bsky.social shows greater discrepancies resulted in less nonverbal synchrony and affected decisions.

What if you had a real encounter, then used genAI to model it, and weeks later relived the memory in VR?
Largescale, longitudinal study by @portiawang.bsky.social at JCMC.
Reliving past memories caused groups to be better, in speech, in gestures, and in outcomes.

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.

People become attached to places they spend time in. 3D maps allow visits in VR. Santoso & colleagues show that visiting distant locations makes even politically conservative participants care about real climate change news in that city, compared to static images.

💡Can we trust synthetic data for statistical inference?
We show that synthetic data (e.g., LLM simulations) can significantly improve the performance of inference tasks. The key intuition lies in the interactions between the moment residuals of synthetic data and those of real data

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.
