ParkiScan — An Educational AI Demo on Facial Motion Analysis

⚠️ EDUCATIONAL DEMONSTRATION ONLY ⚠️

ParkiScan is a student research project, NOT a medical device, NOT FDA-approved, and NOT a diagnostic tool. It cannot detect, diagnose, treat, cure, or prevent Parkinson's disease or any other condition. The output is a model demonstration only — not a health assessment, screening, or medical result. Always consult a licensed healthcare professional for any medical concerns.

WHAT THIS APP IS

ParkiScan is a hands-on educational demo that shows how artificial intelligence and computer vision can analyze patterns of facial motion. It was built as a student research project to help learners, educators, and curious users explore AI in a transparent, accessible way.

HOW THE DEMO WORKS

1. Open the app and acknowledge the educational-use disclaimer

2. Tap "Start Demo Scan"

3. Record a short video of your face making natural expressions

4. The app extracts 468 facial landmarks and runs them through a machine learning model

5. View the model's raw output and feature breakdown for educational discussion

WHAT YOU'LL LEARN

ParkiScan is designed as a teaching tool that demonstrates:

• Real-time facial landmark detection using Google's MediaPipe Face Mesh

• Feature engineering from raw landmarks:

- Eye Aspect Ratio (EAR)

- Mouth Aspect Ratio (MAR)

- Jaw angles

- Movement velocity and acceleration

• How a machine learning model produces an output from these features

• Why ML model outputs include uncertainty and require careful interpretation

• Why responsible AI in healthcare requires transparency, disclaimers, and human oversight

EDUCATIONAL FEATURES

✓ First-launch acknowledgment that clearly explains the app's purpose

✓ Demo output labeled as model output, not a health result

✓ Educational breakdown of facial motion features

✓ "Known Limitations" section explaining where the model can fail

✓ Designed for classroom demos, science fairs, and self-study

✓ Encourages critical thinking about AI in medicine

WHO THIS APP IS FOR

• Students learning about AI, machine learning, or computer vision

• Educators teaching applied AI or biomedical engineering concepts

• Science fair and research project participants

• Anyone curious about how AI models analyze visual data

KNOWN LIMITATIONS (TRANSPARENCY MATTERS)

• Trained on a small, non-clinical dataset

• May not generalize across age, ethnicity, or gender

• Sensitive to lighting, camera quality, and camera angle

• Produces false positives and false negatives

• Has not been validated against any clinical standard

• Cannot detect, diagnose, or rule out any disease

PRIVACY

ParkiScan respects your privacy. Videos are sent to a processing server only to run the AI demo and are not retained. Saved demo outputs live only on your device, not in the cloud.

IMPORTANT DISCLAIMERS

• ParkiScan is NOT FDA-approved.

• ParkiScan is NOT a clinical or diagnostic tool.

• Demo outputs have NO medical validity and should NEVER be used as a health assessment.

• The model can produce false positives and false negatives.

• Do not use this app to self-diagnose or to evaluate anyone else.

• If you have health concerns, consult a qualified healthcare professional — only a licensed neurologist can diagnose Parkinson's disease.

BUILT WITH

ParkiScan was built using open-source tools including Google MediaPipe, scikit-learn, OpenCV, Flutter, and Python. It is shared as an academic learning project, not a commercial product.

OUR GOAL

We hope ParkiScan inspires students and educators to explore how AI can responsibly support human health — while always recognizing that real medical decisions belong with qualified medical professionals.

Thank you for using ParkiScan as a learning tool.
