Help systems for gestural interfaces and their effect on collaboration and communication
Davy Vanacken, Karin Coninx · Document Server@UHasselt (UHasselt) · 2014
Due to limited discoverability and standardization, people often have difficulties with learning and remembering all the gestures of a gestural interface. To overcome these difficulties, help systems are integrated to enable users to quickly explore the available gestures. These systems typically target single-user applications and research is mainly focused on studying the efficiency of various kinds of help. In this paper, we study textual and animated help in a collaborative tabletop game. We not only consider the efficiency of the help systems, but we also examine how they impact collaboration and communication. Our study shows that animated help has a positive effect on the level of collaboration, as users work together to explore and learn the game.
