Indirect multitouch interaction on large screens

Participants : Géry Casiez [correspondant] , Jérémie Gilliot, Nicolas Roussel.

Multitouch interaction shows its limits with large display surfaces. Indirect interaction allows to use control surfaces that are much smaller than display surfaces. Absolute indirect interaction raises accuracy problems and relative indirect interaction only allows to interact with a single cursor. We present a relative indirect multitouch interaction technique allowing to create, control, delete several cursors without sacrifying precision for interacting with small objects (Figure 6 ) [25] .
