  Interest in and development of touchless gestural interfaces has recently
exploded, fueled by the diffusion of both commercial midair gesture platforms
and public interactive displays. This paper focuses on an application based on
Microsoft Kinect that allows students to browse a university website, hosted on
a public display, through simple gestures. We present two empirical evaluations
where we evaluated how users react to this new way of interaction. In addition
to confirming the current lack of standards, our results provide some
inspiration for the design of touchless interaction.
