Beyond time and error
Weidong Huang, Peter Eades, Seok‐Hee Hong · 2008
Time and error are commonly used to measure the effectiveness of graph drawings. However, such measures are limited in providing more fundamental knowledge that is useful for general visualization design. We therefore apply a cognitive approach in evaluations. This approach evaluates graph drawings from a cognitive perspective, measuring more than just time and error. Three user studies are conducted to demonstrate the usefulness of this approach.
