Evaluation of Visualization Techniques for Communicating Off-Screen Data

Worldwide, the use of mobile devices like tablets has begun to integrate themselves in people’s daily lives. People have thus begun to bring over desktop applications, more specifically visualization applications, into the mobile atmosphere. However, this brings forth some challenges, like how to manage screen space and how the visualizations should present the relevant information. Our take on this was to use various aggregations that would allow users to see data elements that would otherwise be off-screen. We thought it was best to create a variety of different aggregations, allowing us to figure out the best method of the group. While creating our survey questions however, we realized that it would better suit us to figure out the strengths and weaknesses of each aggregations instead of looking for the best one. Our survey asks a variety of questions to the respondents on various different topics within visualization, so that we can figure out the purpose and best use of each of our aggregations.
