A health management application with QR-Code input and rule inference

Abstract

Mobile phone is an indispensable tool in modern life. Each person can have more than one mobile phones, or even smart phones. Apple iPhone, leading the trend of smart phone applications, has brought many previously unthinkable possibilities in recent years. We have developed a health management application (app) run on iPhone. It uses the QR-Code to input calorie and nutrition information of food, snacks and drinks. This is a novel way to record what the user eats/drinks. A set of diet rules is also built within the app. With these data, the app can provide diet recommendations to the user following the rules. We aim to utilize the ease-of-use of the smart phone to achieve personal health management anytime, anywhere.
