The present disclosure relates to an augmented reality based user guidance system for multi-step medical procedures, the system comprising an augmented reality device (10, 30) comprising a display unit (14, 34) arranged to present artificial information that can be overlaid on an original scene, a sensor unit (18, 38), a processing unit (22, 42), at least one first marker (142, 144, 146, 148) that can be detected by the augmented reality device (10, 30), wherein the at least one first marker (142, 144, 146, 148) is associated with an object (132, 134, 136, 138) to be used in a defined step of the medical procedure, wherein the medical procedure comprises at least one step that requires a user action, wherein the augmented reality device (10, 30) is arranged to monitor a scene and to detect and track the at least one first marker (142, 144, 146, 148), provide user guidance to execute the medical procedure, detect whether user actions comply with the medical procedure, based on a detected state of the at least one first marker (142, 144, 146, 148), and when the augmented reality device (10, 30) detects an erroneous user action, provide corrective user feedback to the user. The disclosure further relates to a corresponding method and to a use of an augmented reality device (10, 30) in a system for user guidance. |
