During Spring term 2012, Interactive Media meet with Digital Arts instructor John Park to discuss how we could help him increase instructional engagement in large lecture classes. John wanted to use mobile devices that his students were bringing to class to add interactivity. He also wanted a system that could send Open Sound Control messages in order to visualize student responses using digital processing sketches. After surveying the current product market, Interactive media found that no existing tools met the project requirements. With this in mind, we began the design and development of Ripple.
