Techniques d'interaction exploitant la mémoire pour faciliter l'activation de commandes

Abstract : To control an interactive system, users usually have to select commands by browsing lists and hierarchical menus. To go faster, they can perform gestural shortcuts. However, to be effective, they must memorize these shortcuts, which is a difficult task when activating a large number of commands. In a first part, we study the advantages of positional (pointing) and directional (Marking menus) gestures for command memorization, as well as the use of the user's body as an interaction surface and the impact of two types of semantic aids (stories, images) on the effectiveness to memorize. We show that positional gestures make learning faster and easier, and that suggesting to users to create stories related to commands significantly improves their recall rate. In the second part, we present bi-positional gestures that allow the activation of a large number of commands. We demonstrate their effectiveness using two interaction contexts: the touchpad of a laptop (MarkPad) and a smartwatch (SCM).
