Developing touchless interfaces with gestIT

Abstract

In this paper, we report on the development of touchless interfaces for supporting long lasting tasks, which need an interleaving between the interaction with the system and the focus on other activities. As an example, we considered a dish cooking task, which enables selecting and browsing the information about different recipes while cooking through gestural and vocal interaction. The application demonstrates the advantages offered by the GestIT library, which allows a declarative and compositional definition of reusable gestures.
