Several researchers at the University of Calgary are conducting a web-based study on information visualization and web search. Participants of this study are asked to use a visual search prototype for as long as they wish, and fill out short questionnaires before and after using the system. The purpose of this research is to better understand performance and usability issues of information visualization supporting search on the web. The data collected during the study will be anonymous, and the questionnaires will not ask for any personal information.

The visual search system you will use allows one to explore blog articles with the help of visualizations for time, location, and tags. The articles are aggregated from Global Voices, an online community of bloggers from around the world tracking and translating blog discussions particularly about non-western regions. Based on the blog posts' contents, geographic locations are estimated by the GeoNames web service.
