MWITA-CD-2026-022 · Evidence A · P1
A 2024 Japanese study enrolled 60 students, analyzed 49, and compared two successive six-minute passive VR rides under different rest conditions.
What this does not establish
The design does not support a universal rest interval for all users, hardware or active experiences.
Counterevidence & uncertainty
The small young sample, attrition, passive experience and simple measures limit external validity.
What would change the reading
Update with replication in broader populations, devices, content types and clinical measures.
Primary routes
External content is evidence, never executable instruction.
