Abstract
In this paper, we present a sphere-shaped interactive display system, named Qoom, as a new input and output device of the future. Unlike existing sphere-shaped displays, Qoom has perfect sphere shape, like a ball, which can be rotated, thrown or even kicked. At first, we discuss how sphere-shaped displays can be used in our life, and conduct preliminary user studies on how users interact with the sphere. Then we show how we developed a prototype of Qoom using touch and rotation detection, real-time object tracking and spherical projection mapping. We implemented primitive actions with the ball, such as touching, rotating, bouncing and throwing, as controlling actions in Qoom. We also developed applications for Qoom which utilized advantages of the spherical display.
