In VR, a user's field of view is limited and it is hard to perceive the entire space at once. Off-screen visualizations can help to overcome this issue. In this project, you will explore and implement different offscreen visualization possibilities for various scenarios and evaluate their performance.
VR environments can be used to visualize abstract visualizations of data, such as a 3D scatterplot. Prior research led to notion of error caused by "self-occlusion" - i.e. objects were occluded by the viewer himself (viewer stands in object) or objects were at unfortunate positions relative to the viewer (above, underneath, behind). Aim of this project is to find a way to reduce this error by giving the observer hints where objects outside the field of view are, to draw his attention to clusters or spots of interest.
