Each year's conference has a theme, around which the conference planners organize discussion panels designed to integrate and promote discovery, learning, and engagement as panelists and audience members from different regions of the world take up the conversation on particular topics. The conference also includes annual plenary sessions featuring panels or keynote speakers. One of the plenaries is the Interactive Paper Session, in which participants display their work in the form of visual poster presentations and are awarded based on both the merit of their research and the visual quality of their presentations.
