Time and error measures have limitations in revealing in-depth
insights into effectiveness of graph visualizations. For better
evaluations, this book introduces a cognitive approach. Three
evaluations are presented with each using a different method
measuring more than just time and error. These methods include
purpose-designed questionnaires and interviews, cognitive load
measures and eye tracking technology. Contributions of this work
fall into two areas: evaluation methodology and domain knowledge.
Our methodological contribution is that we define and apply a
cognitive approach in evaluation of graph visualizations. A large
set of empirical results and observations are produced
demonstrating the usefulness of the cognitive approach.
Contributions in improving our domain knowledge are diverse. These
include (but not limit to) human sociogram perception conventions,
a construct of cognitive load, a model of performance, mental
effort and cognitive load, new measures of cognitive load and
visualization efficiency, a new concept of geodesic-path tendency.
This work should be useful to practitioners, researchers and
students in Visualization, User Interface and Human Factors fields.
