PROFILE
Yiren Ding
Worked on the revisit-studies/study repository, delivering interactive data visualization features and experiment management tools over five months. Developed Vega-based visualization components and integrated signal tracking to enable real-time analytics and replay functionality, using React and TypeScript for robust UI and state management. Enhanced experiment workflows by introducing an RGB color matching game and a Stroop color-word experiment, both with provenance-aware replay and improved audio handling. Addressed backend integration with Firebase and Firestore for progress tracking, implemented dynamic data models, and refactored code for maintainability. Focused on clear documentation, schema validation, and UI/UX improvements to support reliable, reproducible research workflows.

Feb 1, 2026February 2026 monthly summary for revisit-studies/study. Key features delivered: RGB Color Matching Game introduced with real-time RGB feedback, replacing the previous color task; Stroop Color-Word Experiment deployed with new state management, UI changes, and provenance-aware replay (including introduction page updates); Audio Recording UX improvement ensuring recording stops when navigating to trials that do not require audio. Major bugs fixed: fixed a state-missing bug in the Stroop demo to ensure reliable experiment replay; bug fix for audio recording not stopping when navigating to a completed trial. Documentation and Comment Cleanup across components to improve clarity and maintain maintainability. Overall impact: enhanced user engagement and data quality for experiments, improved reliability of playback and provenance tracking, reduced risk of unwanted audio capture, and better developer onboarding and maintenance. Technologies/skills demonstrated: React-based UI work, modern state management patterns, provenance-aware replay with trrack integration, audio lifecycle handling, and thorough code/documentation hygiene.
