A Wall-Sized Focus Plus Context Display

A Wall-Sized Focus Plus Context Display
In this paper we present a wall-sized input system with high accuracy input in the center and lower precision tracking on the remaining parts of the wall. This work complements the concept of focus plus context displays where output quality in the center is better than in the periphery. Our contribution is to realize a similar concept for the input direction. A high precision tracking unit in the center provides a workspace with high interactivity, while four additional cameras placed in the corners of the wall provide lower precision tracking and hence much coarser interactivity on the entire wall. In our prototype this multi-precision input solution is combined with a focus plus context display, thus providing two levels of interactivity in both the input and output direction. With this setup, we have implemented two example applications to demonstrate the benefits of variable precision input.
