Investigating uni-stroke gesture input for diagram editors on large wall-mounted touchscreens

Nowadays, touch-input devices are widely available. The use of such touch input devices, e.g., large wall-mounted touchscreens in (team) meeting rooms appear appropiate and desirable. Thus, team meetings can change from one-man-presentation-shows towards collaborative and interactive developing of plans and processes via designing and creating its corresponding diagrams. In this paper, we present an approach for interacting with diagrams using uni-stroke touch gestures. We focus on large wall-mounted touchscreens and present an editor design for such environments. In order to validate the usability of our approach we report on the results of a user study with a diagram editor for Business Process Modeling Networks.
