This paper presents computationally and physically augmented desktop objects - “Things that hover” - that is capable of moving autonomously on desktop, and discusses about technical mechanisms, future possible interaction styles and applications based on this architecture. A goal of the design is to create self-moving robotic modules on top of a flat surface. Integrating lightweight piezoelectric air-blow actuators and contact-less power providing technology from desktop surface, tiny robots can hover and control the direction of movement without any battery, which illustrates that our approach is practically feasible.
