Defining gestural interactions for large vertical touch displays

Abstract

As new technologies emerge, so do new ways of interacting with the digital domain. In this paper, the touch interaction paradigm is challenged for use on large touch displays of 65 in. in size. We present a gesture elicitation study with 26 participants carried out on twelve actions commonly used on touch displays. The results and analysis of 312 touch gestures revealed agreement rates for each action. We report several findings including the results of a set of ten unique (and a few secondary) gestures, a taxonomy classifying the defined gestures, a pilot study on the defined gestures, and explicit design implications. We discuss the results and include several important factors for future considerations. We aim at helping future designers and engineers to design interactions for large touch displays.
