User-Evaluated Gestures for Touchless Interactions from a Distance

Abstract

Very big displays are now commonplace but interactions with them are limited, even poorly understood. Recently, understanding touch-based interactions have received a great deal of attention due to the popularity and low costs of these displays. The direct extension of such interactions, touch less interactions, has not. In this paper we evaluated gesture-based interactions with very big interactive screens to learn which gestures are suited and why. In other words, did ‘Minority Report’ get it right? We aim to discover to which extend these gesture interfaces are technology-driven and influenced by prototyped, commercial and fictive interfaces. A qualitative evaluation of a gesture interface for wall sized displays is presented in which subjects experienced the interface while completing several simple puzzle tasks. We found that simple gestures based on the act of pressing buttons was the most intuitive.\ud \u
