Reviving a medical wearable computer for teaching purposes

In 1978 the author constructed a medical wearable computer using an early CMOS microprocessor and support chips. This device was targeted for use by health-conscious consumers and other early adopters. Its expandable functions included weight management, blood pressure control, diabetes care, medication reminders, smoking cessation, pediatric growth and development, simple medical database, digital communication with a doctor’s office and emergency alert system. Various physiological sensors could be plugged-into the calculator-sized chassis. The device was shown to investor groups but funding was not obtained; by 1992 the author ceased pursuing it. The Computing and Mathematics Chair at a local University, a NASA acquaintance, approached the author to mentor a CS capstone course for Summer 2012. With the author’s guidance, five students proceeded to convert this medical wearable computer design to an iPhone-based implementation using the Apple Xcode Developer Kit and other utilities. The final student device contained a body mass index (BMI) calculator, an emergency alert for 911 or other first responders, a medication reminder, a Doctor’s appointment feature, a medical database, medical Internet links, and a pediatric growth & development guide. The students’ final imple-mentation was successfully demonstrated on an actual iPhone 4 at the CS capstone meeting in mid-Summer.
