A Multi-user Interactive Public Display with Dynamic Layout Optimization

In this paper, we propose a user interface that allows multiple users to obtain information interactively and perform simultaneous operation on a public display. Users can interact with the display using hand gestures, which enables many users to easily and remotely use the system. A window pops up when a user selects an item on the screen, and information about the item is displayed in the window. In order for each user to effectively use the screen and also not to be interfered with by other users, the system dynamically optimizes the position and size of each window. We created a map guidance application to confirm the effectiveness of the proposed user interface.
