# D.U.C.K. - XR Dynamic User Context Kit > Mixed-reality system on **Meta Quest 3** that visualizes real-time biomarker data to study how it affects behavior in social and everyday settings. --- ## What is D.U.C.K.? **D.U.C.K.** (XR Dynamic User Context Kit) collects biomarker data from the user and from people they interact with: - Heart rate, posture, sweat, voice, facial expression - Displays it in real time via mixed reality on the Meta Quest 3 - **Goal:** NeuroSwarm - study how access to this biodata changes social behavior --- ## Tech Stack | Layer | Technology | |-------|------------| | MR App | Unity, C#, Meta SDK | | Posture Sensor | Arduino, C++ | | ML | CNN (facial), RNN (auditory emotion) | --- ## Documentation | Doc | Description | |-----|-------------| | [PROJECT.md](docs/PROJECT.md) | Short plan, goals, phases | | [ProjectProposal.md](docs/ProjectProposal.md) | Full proposal, literature, hardware/software | | [PlanOverview.md](docs/PlanOverview.md) | Features, MVP, Phase 1-3 | | [ProjectBrainstorm.md](docs/ProjectBrainstorm.md) | Ideas and literature notes | --- ## Repo Layout ``` D.U.C.K/ docs/ Project plan, proposal, overview, brainstorm arduino/ Posture sensor and other sensor firmware ``` Unity project will live in a subfolder (e.g. `D.U.C.K-Unity/`) when created.
