Plastic pollution in oceans and freshwater sources is now considered one of the most significant environmental threats facing aquatic plants, animals, and humans globally. This research project aims to design a mobile application prototype to investigate the possibilities of technology to potentially communicate ideas in order to raise awareness. Experience design plays an increasingly substantial role in human-computer interaction. The project investigates human actions by providing gamification tasks, and it studies user feedback through a step-bystep building process. The research project studies the interface design and user experience design methods before designing Low-fidelity prototypes (Paper prototypes) and High-fidelity prototypes (Digital prototypes) to create an application design along with a step-by-step user feedback process. The project further studies the potential of a mobile application to identify, observe, and convey this issue with narrative gamification methods. It examines the behaviour impact through user feedback to help prevent plastic from affecting the planet.
