Abstract

A system includes a breathing apparatus, a touch screen unit and a processing unit. A first content is displayed at a first screen location of the touch screen. Upon a user input, comprising a gesture of one or more gestures, at the first screen location, a second content related to the first content is selected and displayed in dependence of the gesture and the first content. The first content (30) is free of an indication of the second content, such as an indication comprised in the list of an icon, soft-button or a menu configured to activate the second content upon user selection on the touch screen.
