This research project aims to create an interactivity system for an interactive art exhibit named StairWELL. The StairWELL project is a sculpture that focuses on the emotional wellness of students through art. The interactive technology design is broken down into three components: a mobile device interface, a data processing server, and sculpture visualization. Each of these components has been defined to help the larger StairWELL team achieve its artistic goals. The goal of this paper is to show that mobile devices can be used as an effective participation method for interactive art installations. It also aims to show how an interactive art piece can accept data from many users in rapid succession.
