Abstract(ENG)

In recent years, the interactive systems with large display have been on the rise, and research on these systems is increasing. While prior research has explored various interaction techniques and input devices developed for large display, it focused on interaction devices used at specific distancesthe display. This research introduces a multi-scale user interaction approach that utilizes a multi-touch screen, freehand gestures and mobile interfaces to help users seamlessly interact with the interactive system regardless of their distancethe display. An experiment was conducted to evaluate how users adopted the multi-scale user interaction to more effectively perform various user interaction tasks. The result showed that the multi-scale user interaction helped users improve their overall task performance. It also found that users tended to utilize different multi-scale user interfaces to complete different kinds of tasks.
