Advanced interface technologies for interactive multi-user displays

Imagine trying to share electronic documents on a communal digital work surface just as you would share paper documents at a meeting table. Fundamental limitations of conventional personal computer technology make this scenario difficult. To address this issue, researchers have begun to explore the use of interactive, multi-user displays, such as interactive wall and tabletop display systems to support collocated collaboration. These systems enable collaborators to interact with digital information, such as maps, images, documents, and sensor data, on large, digital work surfaces. However, designing effective interfaces for these systems is challenging due to their large size, shared input space, and, in the case of a digital tabletop, horizontal display orientation. This research program addresses the lack of suitable interfaces and associated software applications for these systems. It will contribute improved software user interfaces for interactive, multi-user display systems. It will also improve our understanding of how interactive wall and tabletop systems can be effectively utilized in the context of real world collaborative activities. Through this research, students will be trained in human-computer interaction, collaborative technology design, and qualitative and quantitative research methods, which are critical skills for industries developing information technologies to support teamwork, including the defence, healthcare, education, and corporate industries.
