Adoiraccourcix: multi-touch command selection using finger identification

Abstract

Hotkeys are a critical factor of performance for expert users in WIMP interfaces. Multi-touch interfaces, by contrast, do not provide such efficient command shortcuts. We propose Adoiraccourcix, which leverage finger identification to introduce quick command invocation integrated with direct manipulation in this context. After presenting the concept behind, we illustrated Adoiraccourcix in a vectorial drawing application and ran preliminary user studies comparing Adoiraccourcix to classical user interfaces. Results suggest that once mastered, Adoiraccourcix provides very powerful means of interaction.
