Abstract : During the last decade, touch interfaces have become more and more ubiquitous. A lot of software applications initially designed for desktop computers have now a tactile counterpart. However, the limited expressiveness of the touch modality restricts drastically the amount of features available on touch applications. Researchers have been exploring different tracks on how to augment this expressiveness, notably through finger identification. While the literature mainly focuses on tackling the technological challenge, this dissertation aims at better understanding its use in order to provide guidelines for designing interaction techniques. We first summarize existing technologies, present our prototypes and evaluate the use of fingerprint recognition, that we perceive as the most promising solution with the aim of being integrated in consumer devices. Through controlled experiments, we study the differences of performance and preference between fingers, the influence of finger identification on user strategies to complete tasks. We also explore how to integrate this new information along existing interaction techniques and help users grasp the rich vocabulary provided. Our works lead to guidelines for designing interaction techniques leveraging finger identification that we implement in three different interaction contexts (tabletops, tablets and smartphones) through Adoiraccourcix, an interaction technique combining command selection and parameter manipulation.
