OrthoZoom: 1D Multi-Scale Navigation

OrthoZoom Scroller is a novel interaction technique that improves target acquisition in very large one-dimensional spaces. OrthoZoom Scroller requires only a mouse to perform panning and zooming in a 1D space. Panning is performed along the slider dimension while zooming is performed along the orthogonal one. We conducted a controlled experiment showing that OrthoZoom Scroller is about twice as fast as Speed Dependant Automatic Zooming to perform pointing tasks whose index of difficulty is in the 10-30 bits range.
