Brief description of project goal

Type II Diabetes is fast becoming one of the most pervasive and costly diseases to treat in the United States. Emerging data shows that lifestyle changes in the early-diabetic stage can potentially reverse the condition or at least postpone dramatically the full onset of the disease. Furthermore, learning to control full type II diabetes is a task that requires a great deal of individualized experimentation and monitoring. Better glucose control will have remarkable quality of life improvements for patients and remarkable cost savings possibilities for the medical care system.

This development effort will become a component in the comprehensive physiologic monitor for patients with chronic diseases that our team is developing on the PDA/Smartphone platform. The goal this semester is to develop a Type II-Diabetes Lifestyle Coach (TDLC) system that will enable patients to learn to control their blood glucose levels via a PDA-assisted data logging process that tracks reactions to food (type, quantity, and combinations) and monitors the effects of regular walking, jogging, or running. Long term trend analysis will demonstrate to the patient the value of continuous attention to their disease and the mitigation of adverse side-effects.

The Type II-Diabetes Lifestyle Coach (TDLC)

A software package needs to be developed than runs on a PDA, either HP IPAQ or Apple IPod Touch. Gait data along with body temperature will be sampled by sensors and comprise the exercise data-set. A detailed food journal must be made available to the patient users and will form the basis of dietary input on the hardware via an appropriate GUI. This food information, together with patient-user entered blood glucose values will be used for blood glucose analysis. Pre, post and 2 hr post eating blood glucose data as well as daily weight and blood pressure values will be entered by the user. The PDA passes this physiologic & user lifestyle data from the ambulatory unit to a PC via USB connection or via SC-card.

A PC based software system will perform data processing, report generation, and user interface. The PC also performs both long-term and short-term data visualization and performs trend and event analysis on the entire set of stored data residing within the PC. The data analysis will be specified by the project sponsor for the team.

This project build on the iPAQ hardware & sensor system developed by a CS 5150 project in 2009.
