Maintaining any diet comes primarily through fixing what and when you eat. However, tracking and recording every single meal can be tricky. The experimental FitByte technology, which is being developed at Carnegie Mellon University (USA), is designed to solve this problem. Its essence lies in the use of several sensors that can be installed on glasses of any manufacturer.
The basic unit of the system is the infrared movement detection mechanism, which is located on the front of the glasses. It recognizes the characteristic hand gestures associated with eating and drinking. These movements activate the camera, which captures the image of the consumed food or drink. By linking the obtained data, the system makes it possible to identify specific patterns of human eating behavior. At this stage of development, the user still has to independently determine which foods and drinks were photographed. However, in the end, developers will completely transfer this function to an intelligent computer vision system.
FitByte also has six inertial sensors, which are located in the earhooks of the glasses and on the bridge of the nose. They record the movements of the jaw associated with chewing, as well as vibrations of the throat when swallowing.
All data is processed offline inside the glasses themselves, keeping a record of what the user ate and drank, how much and at what time. In the future, non-invasive sensors can be added to the system that will monitor blood glucose levels and other physiological parameters. It is also planned to develop a special companion application. According to reports, the product will go on sale in about three years.
