Abstract: Disclosed are a method, a system and a navigation device for generating and controlling an interaction object, which is preferably in the form of a context menu, on a display unit. In at least one embodiment, the method includes presentation of the interaction object by way of at least one presentation signal from the navigation device and selection of at least one functional element from the presented interaction object by way of at least one selection signal from the navigation device, wherein the selection can be made independently of a movement by the navigation device and wherein the at least one functional element to be selected and/or the selected at least one functional element is presented at a constant location on the display unit by moving within the interaction object or by moving the interaction object.

Abstract: A method is disclosed for controlling the display of activation elements for tools for editing medical data on a user interface in a computer-based, medico-technical system. In at least one embodiment, the activation elements are displayed in an activation element area, divided into various segments, of the user interface on the basis of the medical context. The doctor is thus able to select the tools clearly on a task- or indication-specific basis without an image data area of the user interface being concealed by the activation elements.
