An extracorporeal blood treatment system (10, 100) comprising: extracorporeal blood treatment apparatus to perform an extracorporeal blood treatment, wherein the extracorporeal blood treatment apparatus comprises a blood circuit to circulate blood from a patient during the extracorporeal blood treatment, wherein the blood circuit is connectable to the patient using venous and arterial blood lines (130, 132); a display apparatus comprising a graphical user interface (200, 202, 204) configured to depict a human-shaped graphical element and one or more process feature graphical elements (212, 214, 216), the human-shaped graphical element corresponding to connection of a patient to the blood circuit using the venous and arterial blood lines, each process feature graphical element of the one or more process feature graphical elements corresponding to a different process feature of the extracorporeal blood treatment system; and a computing apparatus comprising one or more processors, wherein the computing apparatus is operatively coupled to the extracorporeal blood treatment apparatus and the display apparatus, wherein the computing apparatus is configured to: display on the graphical user interface (200, 202, 204) the human-shaped graphical element and the one or more process feature graphical elements (212, 214, 216) using the one or more processors, wherein the human-shaped graphical element and the one or more process feature graphical elements are separated by space, characterized in that the human-shaped graphical element is movable proximate the one or more process feature graphical elements to indicate that the venous and arterial blood lines are connecting the patient to the blood circuit; and in that the computing apparatus is further configured to: automatically moving the human-shaped graphical element proximate the one or more process feature graphical elements (212, 214, 216) to indicate that the venous and arterial blood lines are connecting the patient to the blood circuit in response to the patient being connected to the blood circuit; and/or allowing a user to move the human-shaped graphical element proximate the one or more process feature graphical elements to indicate that the venous and arterial blood lines are connecting the patient to the blood circuit. extracorporeal blood treatment apparatus to perform an extracorporeal blood treatment, wherein the extracorporeal blood treatment apparatus comprises a blood circuit to circulate blood from a patient during the extracorporeal blood treatment, wherein the blood circuit is connectable to the patient using venous and arterial blood lines (130, 132);
