Recently, a research team at the University of Passau, Germany, developed a very interesting Diet Eyeglasses using 3D printing technology. This special lens can accurately detect your chewing activity through sensors, so that you know exactly what you are eating. What and how much to eat. The researchers presented the invention at the EEE Body Sensor Networks conference in San Francisco. According to Tiangong, it is part of the WISEglass project led by Professor Oliver Amft of Passau University. In addition, the researchers will detail the results in the forthcoming paper "Diet eyeglasses: Recognising food chewing using EMG and smart eyeglasses", which will Published at the International Conference on Wearable and Implantable Human Sensors. It is reported that the WISEglass project itself is completely built around smart glasses. “WISEglass's vision is to embed electronic components with sensing and processing functions into ordinary glasses.†The project leader said: “WISEglass can be used to distinguish between different activities of daily life.†Monitoring your eating habits is just an application of WISEglass that can be embedded. Part of it - other applications include physical health monitoring, behavior recognition, wireless gaming and more. From the outside, this 3D printed prototype glasses looks very normal, but in fact it is equipped with an electromyography (EMG) sensor inside its frame. These flexible fabric electrodes are capable of detecting the contraction of the facial muscles, the diaphragm, when the user is in contact with the skin behind your ear. In addition, the location of these sensors is behind the ear, as Amft and his team found that this position provides the best skin contact and therefore the best signal quality. And this 3D printed prototype glasses also has a small processor and battery behind the ear. “Although we all know that EMG can be used to assess chin contraction in a clinical setting, we believe that the use of EMG to detect inconspicuous chewing is a critical step toward viable dietary testing. The end result shows that EMG can provide highly accurate chewing tests that help with timing analysis of food intake," they said. In fact, studies have shown that a variety of different foods can cause different muscle contractions, and this contraction can be distinguished. Eight subjects carried out various activities with eating glasses, including eating various foods, drinking water, coughing, talking and turning their heads. The researchers found that the lens's ability to recognize is quite amazing, it can distinguish the muscle contraction produced by biscuits, bananas, bread, carrots and candy of different textures. Although this 3D printed diet glasses can't identify every kind of food – many foods have similar textures – but its application prospects are still very large. Researchers believe that by connecting with other sensors and Bluetooth applications, these smart glasses can be used to create "personalized meal monitoring systems." For example, a microphone can be added to monitor the sound of your chewing and biting, providing more information for finding the right food in a database.
