Visual techniques for exploring alternatives and preferences in Group Preferential Choice

University of British Columbia

Group Preferential Choice is when two or more individuals must collectively choose among a competing set of alternatives based on their individual preferences. In these situations, it it can be helpful for decision makers to visually model and compare their preferences in order to better understand each others’ points of view. Although a number of tools for preference modelling and inspection exist, none are based on a comprehensive understanding of the demands of Group Preferential Choice in particular. The goal of our work is to understand these demands and explore the space of possible visualizations to support them. We make progress toward this goal in three steps. First, we characterize the scope of Group Preferential Choice by examining a diverse set of real-world scenarios. In particular, we identify sources of variation in preference models, goals, and contexts. Second, we produce a detailed model of abstract tasks to support the goals identified in the first step. Finally, we analytically evaluate various designs with respect to these tasks and conclude with recommendations for different classes of users. We believe that these contributions will help designers produce more effective visual support tools for Group Preferential Choice.
