Body Sensing

Guest: Edward Sazonov, PhD, Professor of Computer and Electrical Engineering at the University of Alabama  Fitbit and Apple watches are both on the must-have list for Christmas gear this season. Wearable technology to track exercise, heart rate and other biometrics are incredibly popular. But they still have limits. None have figured out how to track calorie intake accurately, for example. There are ways to guess, but most of these devices require you to go online and record what you eat in order to make the calculations. The problem with that is that it’s a pain to keep up and people are notoriously bad at keeping accurate records of their diet, but researchers at the University of Alabama are making it easier.
