VRdeo revolutionizes educational video creation by separating teaching from camera work. Teachers record entire scene animations in VR while focusing solely on content presentation, then camera operators craft optimal viewing experiences post-hoc. Students can explore recordings interactively in VR or watch exported 2D videos for broader accessibility.
VRdeo began as my master thesis and evolved into a published scientific paper, addressing a fundamental challenge in educational content creation: how to make complex 3D scientific visualizations more engaging and accessible.
As the solo developer and designer, I created VRdeo in close cooperation with Jan Mičan from Loschmidt Laboratories at Masaryk University. While the initial use case focused on recording molecular structures for structural biology, the platform’s design is versatile and applicable to any 3D content that benefits from dynamic, immersive presentation.
The key breakthrough of VRdeo is separating teaching from camera work. In traditional video production, presenters must simultaneously focus on their content and camera positioning, which is cognitively demanding and often results in compromised quality on both fronts.
VRdeo’s Recording Mode allows teachers to focus entirely on presenting and manipulating 3D content naturally—without worrying about camera angles, framing, or recording controls. The system captures the entire scene animation, including the teacher’s avatar for enhanced presence and engagement. Once the teaching performance is complete, camera operators can work in Camera Mode to set up and adjust camera trajectories post-hoc, crafting optimal viewing experiences by strategically positioning cameras throughout the recorded timeline.
Students can then experience the content through Replay Mode, exploring the interactive VR recording directly, or watch polished 2D videos exported for broader accessibility to those without VR equipment.
The recording and replay principle developed for VRdeo proved valuable beyond molecular visualization. This approach has been integrated throughout my subsequent projects:
The ability to record, replay, and analyze 3D interactions provides invaluable insights for researchers, educators, and designers working with immersive content.
Built in Unity for HTC Vive and Oculus Rift, VRdeo implements a three-mode workflow that separates concerns and optimizes each role:
Recording Mode: Teachers immerse themselves in the virtual space with 3D models (such as molecules loaded from the PDB database) and focus exclusively on presenting and interacting with content. The system captures the entire scene animation, including the teacher’s avatar, without requiring any attention to camera operation.
Camera Mode: After recording is complete, camera operators can review the full session and set up camera trajectories strategically. This post-hoc approach enables careful consideration of framing, pacing, and visual storytelling, resulting in high-quality MP4 video exports.
Replay Mode: Students can either explore the recorded VR session interactively, navigating the 3D space at their own pace (even interact with objects when the recording is paused), or watch the curated 2D videos for accessibility when VR equipment is unavailable.
This modular approach to VR content creation informed the architectural decisions in my later work, particularly in designing extensible VR platforms for collaborative learning scenarios.
