Abstract:
Optimizing computer game play necessitates an understanding of specific game design goals
and general presentation strategies, wherein game play can be both challenging and fun. Although only rarely utilized in this context, the ever-advancing field of computer graphics, and particularly non-photorealistic rendering (NPR), hold untapped potential in optimizing game play. We introduce the concept of supportive presentation, wherein graphical presentation planning aims to maximize player enjoyment. To this end, we provide (1) tools and empirical psychological evidence utilizing NPR-specific presentation methods; (2) tools for advanced camera control; and (3) a system for integrating key aspects of game design and
development for supportive presentation. Lastly, drawing on examples of supportive presentation in potential game applications, we outline directions for future research between graphics and psychology to promote a better understanding of the influence of presentation methods.
