Mixed Reality headsets trigger a subconscious caution mode in the brain that makes users move their hands more slowly and reach wider than they do in real life.

Sensorimotor Reorganization of Reach-to-Grasp Movement in Mixed Reality: A Kinematic and EMG Comparison with Physical Reality

The Takeaway
Digital mediation of vision causes the brain to reorganize how it controls body movements even when the objects being touched are physically real. People wearing these headsets display more cautious and exaggerated grasping patterns during simple tasks. The human brain does not treat the combination of digital images and real touch as a perfect substitute for the physical world. This effect persists even when the visual information is technically accurate and synchronized. Engineers designing these systems must account for this inherent lack of trust the brain has in a digitally rendered environment.
From the abstract
PurposeMixed Reality (MR) is increasingly used to simulate ecological interactions by combining virtual visual feedback with real-world haptics. However, it remains unclear whether MR serves as a neutral proxy for Physical Reality (PR). This study investigates how the digital mediation of vision modulates the sensorimotor loop during a reach-to-grasp task, even when tactile consistency is preserved.MethodTwenty-four participants performed an identical reach-to-grasp task in PR and an immersive M
