Famous Death Row Last Meals
A Swiss lab has created a system of sensors and microphones to help dieters keep track of what they eat. A report from The Wearable Computing Laboratory describes how an in-ear microphone (right) was used, with very high accuracy, to identify various foods based on what they sounded like as they were eaten. Other parts of the system include a collar to detect swallowing and hand sensors to detect "food intake related motions." The lab hopes that all of this automation will make it easier for people to keep track of what they eat, as opposed to having to manually take notes about everything they consume in a day.
