Future wearable devices will help you keep track of your diet. At least, that is what Dr. Edward Sazonov, an associate professor of electrical and computer engineering at The University of Alabama, is working on. This is a sensor you can wear around your ear to automatically track your diet. This Automatic Ingestion Monitor detects and captures imagery of food intake to estimate the mass and the energy content of ingested food. The sensor analyzes the movement in the jaw when you are eating and filters out jaw motions.
A wearable device like this can give you a better idea how much you are eating, and what you can do to keep your weight under control. It will be interesting to see how this turns out. The idea is creative though.
