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.

Summary form only given. Our work explores the possibilities of using 3D projection on physical objects - a multi-projector set-up, which we aim to use for exhibition, teaching, design and early prototyping purposes. We also aim to create more immersive and engaging multimedia presentations, and change from conventional 2D media to 3D media by projecting the visual content on a physical object. This video demonstration presents two examples of tangible 3D projections. In our first demonstration we used a sphere shaped object and projected a visualization of rotating Earth on it with five projectors. We have recently done a study [1] that focused on audience's perceptions of 3D projection. Results were encouraging, and we will continue our work with the subject. In another demonstration we used a human shaped model and projected various datasets on it, including muscles, bones and digestive system. This setup contains two projectors, one in the back and the other one in the front of the body. 3D world contains 3D model of the human body and two camera views. In the future we will focus on enabling functional interactions to make projections more useful and interesting e.g. for teaching purposes. Interactions and automatic projector calibrations are the next steps to be implemented and examined in our project.

In this paper we present our work on exploring the possibilities of using 3D projection, instead of 2D displays, for a media installation set-up, which we aim to use for exhibition and teaching purposes. We compare two visual media installations presenting a rotating Earth, one presented on a 2D display and the other projected on a physical 3D object, and present the feedback collected by using the product evaluation cards method.

In this paper we evaluate the possibilities of autostereo-scopic three-dimensional displays in aiding the user in a selection task on a mobile touch-screen user interface. We describe a user study which measures the effectiveness of realistic depth illusion as an emphasizing method in a conventional mobile user interface concept. In our experiment, 35 people completed simple thumbnail visual search tasks, where horizontal disparity, color shading, and their combination were used as the emphasizing method. The results indicate that using disparity alone as a visual indicator does not provide enough support in find-and-select tasks to improve the user performance or perceived comfort with the task. However, when combined with other visual cues, disparity can significantly improve performance and satisfaction.
