New AutoDietary Necklace could Help you Lose Weight
Computer scientist from the University of Buffalo, Wenyao Xu developed a necklace called AutoDietary. It uses a small microphone to listen to the sounds of chewing. Those sounds are matched up to an audio library through a smartphone app. "Each food, as it's chewed, has its own voice," Xu said.
Xu conducted a small study using 12 participants. They were each given water, apples, carrots, cookies, peanuts, walnuts and potato chips. The necklace was able to determine the right food 85 percent of the time.
