Techniques d'interaction collaborative autour d'une table interactive

This paper describes two tabletop interaction techniques for collocated collaborative work. These techniques aim to improve the transitions between individual and collective tasks to improve the collaborative interaction. The first technique is based on common document browsing techniques with the decomposition of the browser into independent components to desynchronize the interaction and to avoid interruptions in collocated users' work. The second technique gives a means to launch graphical objects on the interface without disturbing other users. This technique allows the user to implicitly give the desired orientation and dimensions of the new window before it is displayed on the interface.
