Expanding Research Methods for a Realistic Understanding of Personal Visualization

Personal visualizations have the great potential to provide the benefits of visualizations to everyone in their everyday lives. Their diverse goals combined with the personal data they contain and the contexts in which they are being used, however, make their evaluation particularly challenging and call for a wider perspective on empirical approaches. We need to devise new methods and adapt existing methods from other fields to account for the specific goals and challenges in this emerging research area. An open-minded approach to empirical methods may help us to gain a more realistic understanding of personal visualizations.
