VR medical training for a Dutch hospital — MVP in 2 weeks.
VR Gorilla — a Dutch studio specializing in 360° video — needed an MVP VR training app to demo for a Dutch hospital. Medical students and interns would navigate realistic hospital scenarios, make clinical decisions, and be evaluated. We shipped on Meta Quest in 2 weeks — and the engagement expanded to 5 additional VR / mobile / video projects.

The challenge
Three problems — all at once.
VR Gorilla, a Dutch studio specializing in 360° video, needed to demonstrate VR training capabilities to a Dutch medical institution. The hospital wanted an interactive platform for medical students and fresh healthcare professionals — where 'their decisions determine their journey.'
The MVP had to support Meta Quest with and without controllers, and ship as an internal tool — no public app store distribution, but still polished enough to evaluate VR as a real training medium.
Initial documentation was thin — a few videos and a superficial description. We had to architect the scenario engine, evaluation system, and interaction model from a brief, on a compressed 3-week timeline.
What we did
Seven specific things.
- 01Built an intuitive in-VR UI for navigation, scenario selection, and in-app tasks — usable on Meta Quest with and without controllers (eye-gaze + 2-second hold for selection)
- 02Implemented 360° video playback in stereo with branching decision points — users participate in realistic hospital scenarios and their choices unlock the next round
- 03Designed the scoring + evaluation system — points based on multiple-choice answers and response time, with final performance reports for the institution
- 04Architected a tree-like scenario plot model with rounds (video episodes), each ending in a quiz that determines the next branch
- 05Built two app versions: bundled (all scenarios + assets in the app) and server-loaded (dynamic content downloads for scalability and easier content updates)
- 06Built a custom transition editor for non-engineers to author scenario branches via JSON configuration
- 07Tested and locked optimal video specs for the device: stereo H.264 MP4 at 3840×3840, 30 fps with MPEG AAC audio
