Defining a mid-air gesture dictionary for web-based interaction

This paper presents an empirical evaluation of mid-air gestures in a web setting. Fifty-six (56) HCI students were divided into 16 groups and involved as designers. Then, they proposed a set of mid-air gestures to carry out the identified actions: 99 different mid-air gestures for 16 different web actions were produced in total. Designers validated their proposals involving external subjects, namely 248 users in total. Finally, we analyzed their results and identified the most recurring or intuitive gestures as well as the potential criticalities associated with their proposals.
