A simple handshake and a pulling motion can replace the entire multi-step digital menu process needed to share a virtual reality space.

Allow Me Into Your Dream: A Handshake-and-Pull Protocol for Sharing Mixed Realities in Spontaneous Encounters
arXiv · 2604.19423
The Takeaway
Digital consent protocols in mixed reality become significantly more efficient when they are tied to primitive human gestures. This handshake-and-pull protocol collapses complex synchronization tasks into a single socially intuitive action. Traditional methods require users to navigate buttons, prompts, and menus to grant access to a shared digital world. Returning to embodied movements makes the technology feel more natural and reduces the cognitive load of interacting with virtual objects. Future social interfaces will likely rely more on these ancient physical habits than on new digital icons or voice commands.
From the abstract
Mixed reality systems support shared anchors and co-located interaction, yet they lack a socially legible protocol for entering another person's mixed reality in public settings. We frame this as a protocol problem: co-located MR sharing requires a staged sequence -- Discover, Consent, Confirm, Allow, Spatial Colocation, Sync Objects, Permission Management -- each demanding user understanding and agreement. Using AirDrop and Apple Vision Pro SharePlay as a baseline, we show that MR encounter com
