Objective
In this work, a nutrition system with Internet-enabled PDAs and web server is proposed, which can be used to keep track of user’s diet and workout history, generate warnings of unsuitable food based on users’ body information, and create periodic health reports.
The existing systems have the following main problems. First of all, somebody does not understand how to use the existing systems. To illustrate, the measurement of blood pressure is hard to certain users who do not how to know measure blood pressure. And the amount of workload is hard to measure. Second, the exiting systems do not motivate the users to enter data. Perhaps, the users forget, even detest, entering the data in certain days. Thus, the system cannot work out properly the result based on the incomplete data. Third, the existing systems do not provide notification for user under some situation. For example, when a diabetic orders a dish with high sugar, the existing systems do not give the user a warning.
The proposed system has four types of new services. Patient care service using notice and warning message to helps patients take care of their diseases. Food comparison service compare nutrition facts of different food that users want to choose from, and then recommend users of the more nutrient one. Tips service shows nutrition tips every time the system is activated. Online service includes Food recommendation, Eating pattern recommendation and Health report.
