Evaluation of multi-touch gestures

Abstract

Interaction possibilities are perceived as being diverse and self-evident, especially caused by rapid technology developments. The availability of interaction possibilities is not consciously experienced as something special but it rather appears as an unconscious perception. The process of interaction via touch gestures is nowadays a standard in many technologies. Additional technologies, such as headand eye-tracking have become of great interest regarding agriculture adoption, and they were apparent shown at the Agritechnica 2013- the world's largest trade fair for agricultural machinery and equipmentin Hannover, Germany.The study 'Evaluation of Multi-Touch Gestures' was conducted in co-operation between John Deere GmbH \& Co. $KG(Intelligent Solutions Group)$ and the DFKI GmbH (German Research Center for Artistic Intelligence GmbH). The research objective was to find out, if multi-touch gestures on machines - with a particular focus on tractors - will be applicable for users. In this study, users who used different gestures, while the machine was not moving and while they were driving on the field were interviewed afterwards. To receive their impressions/ and to analyze the results, users had to answer a questionaire including 5 additional further questions to explicite write down their individual feedback. . Users reacted positively towards the applications of gestures. The entire range of testing for this study, the results, a summary, as well as an outlook will be presented in this paper.
