Abstract

We present a new interaction technique for large direct-touch displays called Modal Spaces. Modal interfaces require the user to keep track of the state of the system. The Modal Spaces technique adds screen location as an additional parameter of the interaction. Each modal region on the display supports a particular set of input actions and the visual background indicates the space's use. This "workbench approach" exploits the larger form factor of display. Our spatial multiplexing of the display supports a document-centric paradigm (as opposed to application-centric), enabling input gesture reuse, while complementing and enhancing the current existing practices of modal interfaces. We present a proof-of-concept system and discuss potential applications, design issues, and future research directions.
