This research primarily applies Processing, a framework language for image-processing and Arduino, an open-source electronic prototyping platform to achieve human-computer interaction. The communication between Arduino and Processing completes the combination of software and hardware, thus presenting widespread application and strong visual expression. Moreover, through employing programming languages, designers and artists can create high-quality interactive device art, freely turning their ideas into reality. With the core focus on the global desertification, this research aims to design and produce an interactive device for publicizing the hazards of desertification via connecting hardware (a hand pressure bellow, light strips and wind sensors, etc.) and screen images which can show the continuous spread of desertification across the globe.
