Understanding collaborative usage of large-size screen systems is important for advancing the general study of human-computer interaction (HCI) as well as for guiding the designers while creating efficient interactive large-size systems. This thesis aims to provide guidance for the designers of collaborative large-size screen systems. It therefore gives background information about such systems, defines similarities and differences in existing systems, compares existing design guidelines and principles, tests and validates proposed solutions and offers new guidelines and principles for designing interactive large-size screen systems. In the first part, a literature survey of input devices, output devices, interaction methodologies and collaborative interaction used for large-size screen systems was conducted. This showed that an empirical, systematic and academic study for guiding the design process of collaborative large-size systems is missing. Following a literature review of research methods in the HCI field, an initial system was setup, a gesture library was created and user interface (UI) elements were generated to gather initial findings. Existing design guidelines and principles of well-known platforms were compared and compatible ones were used as input for creating new ones. Thereafter, an empirical laboratory experiment with four major tests, was conducted to test interaction devices, multi-user interaction, collaborative usage and UI elements on a large-size touchscreen system. The results and conclusions of this research should help to inform the design and development of similar HCI systems.
