TUIs and Media

Amongst the operations requiring intensive manipulations media editing and visualization is certainly in the top ten. As a consequence when working with media the GUI and its related devices (especially the mouse) are highly used. This fact naturally raises issues of optimization and ergonomics³: ``is the combination $GUI+Mouse+Keyboard$ the right one when talking about media manipulation and visualization ?'' According to [17] this may not be the case. Therefore, the three articles summarized in this paper propose new approaches competing with the existing methods.
