Pan-zoom coordination in multi-scale pointing

We report some data from an experiment on multi-scale pointing with right-hand panning and left-hand zooming. We use a new metric derived from Zhai and Milgram [6] to quantify pan-zoom coordination, and we show that two-handed input allows parallelism.
