Interactive control modes for robotic fish based informal science learning activities have been shown to increase user interest in STEM careers. This study explores the use of natural user interfaces to engage users in an interactive activity and excite them about the possibility of a robotics career. In this work, we propose a novel natural user interface platform for enhancing participant interaction by controlling a robotic fish in a set of tasks. Specifically, we develop and characterize a new platform, which utilizes a Microsoft Kinect and an ad-hoc communication protocol. Preliminary studies are conducted to assess the usability of the platform.
