Potential limitations of multi-touch gesture vocabulary: Differentiation, adoption, fatigue

Abstract

The majority of gestural interactions in consumer electronics currently represent "direct" gestures related to the direct manipulation of onscreen objects. As gestural interactions extend beyond consumer electronics and become more prevalent in productivity applications, these gestures will need to address more abstract or "indirect" actions. This paper addresses some of the usability concerns associated with indirect gestures and their potential limitations for the typical end-user. In addition, it outlines a number of considerations for the integration of abstract gestures with productivity workspaces. © 2009 Springer Berlin Heidelberg.
