“…The implementation [Huotari & Niemelä 2002] enabled the illustration and rotation of two-and three-dimensional objects on a large two-dimensional display (a 2.4 m × 2.4 m screen). The resolution was 1024 × 768 pixels on the screen.…”

Graphical information system (IS) models are used to specify and design IS from several perspectives. Due to the growing size and complexity of modern information systems, critical design information is often distributed via multiple diagrams. This slows search performance and results in reading errors that later cause omissions and inconsistencies in the final designs. We study the impact of large screens and the two promising visual integration techniques of elision and connecting lines that can decrease the designers' cognitive efforts to read diagrams. We conduct a laboratory experiment using 84 computer science students to investigate the impact of these techniques on the accuracy of the subjects' search and recall with entity-relationship diagrams and data flow diagrams. The search tasks involve both vertical and horizontal searches on a moderately complex IS model that consists of multiple diagrams. We also examine the subjects' spatial visualization abilities as a possible covariant for observed search performance. These visual integration techniques significantly reduced errors in both the search and the recall of diagrams, especially with respect to individuals with low spatial visualization ability. • 27 Additional

User evaluation is a common and useful tool for systematically generating knowledge and validating novel approaches in the domain of Immersive Analytics. Since this research domain centres around users, user evaluation is of extraordinary relevance. Additionally, Immersive Analytics is an interdisciplinary field of research where different communities bring in their own methodologies. It is vital to investigate and synchronise these different approaches with the long‐term goal to reach a shared evaluation framework. While there have been several studies focusing on Immersive Analytics as a whole or on certain aspects of the domain, this is the first systematic review of the state of evaluation methodology in Immersive Analytics. The main objective of this systematic literature review is to illustrate methodologies and research areas that are still underrepresented in user studies by identifying current practice in user evaluation in the domain of Immersive Analytics in coherence with the PRISMA protocol.
