Deviceless Gestural Interaction for Public Displays

This paper introduces a gestures based interaction method to interact with public displays that avoids the use of any device attached to the user. To accomplish interactive tasks, the user just need to position himself in front of the display and interact with the information presented on the screen using his hands. Supported gestures provide navigation, selection and manipulation of objects, as well as panning and zooming at the screen. In order to evaluate how robust the system is in a real public scenario, some criteria that could interfere on the interactive task are evaluated, as the amount of brightness in the environment, and the presence of other persons in the same interaction place. Given the results of the performed tasks, it is possible to conclude that the system, although not behaving correctly in all situations, has potential use if its difficulties are circumvented, most of which come from the inherent limitations of the Kinect, the device used.
