Our group is interested in combining computer graphics and cognitive psychology to produce effective visualizations. Our members mostly come from the Stanford Graphics Lab and the Stanford Psychology Department. One focus of our work has been to produce systems capable of generating effective visual instructions. We observed that hand-sketched route maps are usually easier to use than computer-generated route maps. By studying hand-designed maps, we extracted the cognitive principles that made these maps effective and encoded them within the LineDrive system. An example of the maps produced can be seen to the right, or on MapPoint. More recently, we studied how users assembled everyday objects. We created a system that produces step-by-step assembly instructions given a 3D model as input, with additional grouping and ordering constraints. We presented this work at Siggraph 2003. We have also looked into a method of creating more realistic technical illustrations by spatially compositing photographs of an object taken from a single view under varying light conditions. We will be presenting this work at Visualization 2003.
