System for training an interventionalist to perform an invasive percutaneous intervention or an endoscopic intervention on an organ, by using a tool in this organ, where a merging unit is arranged for merging in real-time in a common environment a real-time 3D model of an end portion of a tool and a pre-computed 3D model of at least a portion of the organ. A display shows to the interventionalist the common environment, so that the interventionalist can see in real-time on the display where the real-time 3D model of this end portion of the tool is located with respect to the pre-computed 3D model of the portion of the organ, thus making the training of the interventionalist possible.

The present invention concerns a clickable knob which can be placed on a touch sensor for providing a physical clickable knob on the touch sensor. The detection of the user input of the clickable knob, i.e. the click state and the rotation state, is detected based on a detection of corresponding click and rotation detection points of the clickable knob by touch pixels of the touch sensor.
