A team of students at the Georgia Institute of Technology has designed a device that allows individuals to constantly compute the amount of calories they burn - even while sleeping.
The device, dubbed HappyHR, is a personal monitor that allows users to measure and compare day-to-day physical and caloric activity.
The name is a reference to the euphoric feeling that follows an intense round of exercise - the 'happy hour.'
"It's a completely converged device. It's a single unit that provides complete fitness monitoring and management," said Garrett Langley, 21, a senior in the School of Electrical and Computer Engineering (ECE) who spearheaded the project.
The small, rectangular-shaped instrument straps to the wrist or ankle, gathering data related to heart rate and exercise.
The information is then transferred via Bluetooth to a PC, where the statistics can be analyzed through Web-based software.
Although the device focuses on calorie counting, Langley envisions more thorough health applications including respiratory and glucose monitoring.
