Multi-touch command selection using finger identification

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. Adoiraccourcix leverages finger identification to introduce quick command invocation integrated with direct manipulation in this context (Figure 3 ). We illustrated its use in a vectorial drawing application and ran preliminary user studies comparing it to classical user interfaces. Results suggest that once mastered, it provides very powerful means of interaction [31] , [44] , [43] .
