Sensory spectacle frame for objectively determining children's screen time (Screentime)

In the Screentime project, Hahn-Schickard is working on the development of a spectacle frame for children that is equipped with various sensors and should therefore make it possible to determine the actual time spent in front of all types of screens (smartphones, tablets, PCs, TVs, etc.).

In the Screentime project, Hahn-Schickard is working on the development of a spectacle frame for children that is equipped with various sensors to enable the time actually spent in front of all types of screens (smartphones, tablets, PCs, TVs, etc.) to be determined. The spectral composition of the light and the distance to the nearest object in the field of vision and the subject's head movements are measured. Hahn-Schickard was commissioned by the Center for Health Promotion and Disease Prevention at the University of North Carolina, where the development is to be used in a large-scale medical study. For this reason, the tasks in the project also include implementing the data infrastructure, namely a smartphone app that downloads the recorded sensor data from the smart glasses via Bluetooth Low Energy and transmits it in encrypted form to a central server. Furthermore, the topic of deriving the actual screen time from the recorded data using machine learning algorithms was dealt with in a master's thesis.
