Interaction in Semi-Immersive Large Display Environments

This paper evaluates interaction methods within the general framework of navigation, selection, and manipulation. It considers large display environments and, in particular, the virtual workbench, comparing this system with HMD and CAVE systems. The paper addresses three issues: (a) identifying the characteristics that set the workbench apart from other virtual environments; (b) determining types, organization, and examples of interaction techniques: (c) evaluating how these techniques perform on the workbench to determine which perform best. The evaluations are based on an extensive set of user observations. Also discussed are some problems that stereoscopic display coupled with interaction bring out
