Cloud Computing

Cloud computing enables AI health apps to process massive health data in real time, run machine learning models, and detect anomalies across millions of users. It provides scalable infrastructure that adjusts to demand and keeps data synchronized across devices and regions.

It also ensures instant global access to health records while supporting secure storage, encryption, and compliance systems needed to protect sensitive medical data.

Computer Vision Health Tracking

Computer vision analyzes facial and visual data from smartphone cameras to assess health indicators. Subtle changes in blood flow, skin tone, eye movement, and facial expressions help estimate heart rate, stress levels, fatigue, and oxygen levels.

It also studies blink rate, pupil dilation, and voice-related signals to understand emotional and physical states. However, accuracy may vary with lighting conditions, skin tones, and camera angles, so results should be interpreted as supportive insights rather than medical diagnoses
