Smart Wristband for Voting

摘要

Nowadays sensor networks are not solely used in industrial settings anymore but are accessible to the public and thus allow for broad and diverse applications. The technical advancement of cyber-physical systems (CPS) paved the way for an easy and fast development of Internet of Things (IoT) devices. In this work, a voting wristband that uses hand gestures and the measurement of the corresponding barometric air pressure for voting has been developed. Audience response systems are often used as a way to improve participation and spark interest in a topic during a presentation. The intuitive wrist movement allows for multiple choice voting results. Textile integration of the wristband guarantees comfort and allows for an adaptable design for different events. Furthermore, an application that makes live updating of voting results and visualization thereof possible was implemented. This illustrates the endless possibilities of wearables and approaches to IoT design with sensors in times of CPS.
