Creating 3D Projection on tangible objects

This paper uses non-planar surface, a sphere shaped object and project a visualization of rotating Earth on it. Previous research has experimented with sphere shaped interactive displays. At Microsoft, Benko et al. built and experimented with a spherical multi touch screen Sphere, and a spherical volumetric display with touch input is described. This demonstration, presented in the paper, does not currently have input functionality, but it is considered as the potential direction for future work. Bimber and Raskar presents techniques involving both hardware and software to implement spatial augmented reality (SAR) installations. Projected multimedia installations or learning material are part of everyday life in museums, exhibitions and schools. This paper takes a step further in creating more immersive and engaging multimedia presentations, and change from conventional 2D media to 3D media by projecting the visual content on a non-planar physical object, a multi-projector set-up, which we aim to use for exhibition, teaching, design and early prototyping purposes.
