AvatarX is a next-generation health monitoring application that leverages AI-powered facial recognition to measure user health vitals.
Project Overview
AvatarX is a next-generation health monitoring application that leverages AI-powered facial recognition to measure user health vitals. The platform has dual portals User and Doctor enabling patients to track their own vitals, while healthcare professionals can invite, monitor, and proactively manage patients in real time. Doctors can also prescribe or share medications through the system, streamlining remote care and clinical workflows.
Objective
- Full Stack Development: Built backend REST APIs (Node.js, Express.js, Knex, PostgreSQL) and integrated them with a responsive frontend (Next.js, Tailwind CSS, JavaScript).
- API Design & Integration: Collaborated on robust APIs for seamless data exchange between user and doctor portals, ensuring secure transmission and real-time accuracy.
- Responsive UI: Developed user-friendly, device-agnostic interfaces for doctors and patients, guiding users through health scans and report review.
Research & Development
Motivation & Market Relevance:
Growing need for remote health solutions, especially post-pandemic, drives innovation in digital monitoring and telehealth. Traditional sensors (wearables) present issues with user compliance and accessibility; facial recognition offers a contactless, user-friendly alternative. Visual avatar technology improves information transfer, situational awareness, and patient engagement, as shown in recent studies.
Core Technology & Architecture :
AI Health Vitals via Facial Recognition: AvatarX uses video-based AI algorithms to analyze facial image data, extracting metrics like heart rate, respiratory rate, and stress levels. This technology is similar to solutions that offer real-time, contactless monitoring validated by clinical research.
Two-Portals System:
- User Portal: Individuals scan their faces for instant feedback on health vitals and receive visualizations or recommendations.
- Doctor Portal: Clinicians invite patients, monitor real-time health data, and prescribe care remotely streamlining workflows and making proactive intervention possible.
- Live Monitoring & Medication Sharing: Doctors can review patient vitals with avatar-based visualizations, communicate recommendations, and share prescriptions instantly.
Project Challenges
The platform was engineered to ensure reliable AI outputs, HIPAA-compliant data security, seamless user flows, and scalable real-time processing.
Accuracy & Reliability
Key challenge is maintaining consistency in facial recognition metrics across varied lighting, backgrounds, and skin tones. Extensive testing and calibration are required to ensure clinical relevance.
Privacy & Data Security
Meeting HIPAA and related privacy standards by encrypting sensitive health data and implementing strict access controls.
User Experience
Designing intuitive flows for non-technical users so that vitals scans and doctor interactions remain straightforward.
Scalability
Building efficient APIs and real-time data piplines for numerous concurrent scans and doctor-patient sessions.
