A computer implemented method comprising: displaying , via a display of an augmented reality, AR, device, a view of image data obtained by a camera of the AR device; tracking a position of a target object within the displayed view; determining a visibility of the tracked target object and/or a virtual object to be superimposed on the tracked target object on the display, wherein the position of the virtual object is dependent on the position of the target object; and generating a trigger signal depending on the visibility; and storing the displayed view; characterized by storing a visibility matrix associated with the stored displayed view, wherein the visibility matrix comprises at least one visibility matrix element indicative of the visibility of the target object; retrieving a respective visibility matrix for a plurality of previously stored displayed views; selecting a plurality of the stored displayed views based on the retrieved visibility matrices; determining a displaying order based on the retrieved visibility matrices; and displaying the plurality of selected displayed views via the display of the AR device or another display of another AR device in the determined order, wherein the selected displayed views are displayed simultaneously and/or successively. displaying , via a display of an augmented reality, AR, device, a view of image data obtained by a camera of the AR device; tracking a position of a target object within the displayed view; determining a visibility of the tracked target object and/or a virtual object to be superimposed on the tracked target object on the display, wherein the position of the virtual object is dependent on the position of the target object; and generating a trigger signal depending on the visibility; and storing the displayed view; characterized by storing a visibility matrix associated with the stored displayed view, wherein the visibility matrix comprises at least one visibility matrix element indicative of the visibility of the target object; retrieving a respective visibility matrix for a plurality of previously stored displayed views; selecting a plurality of the stored displayed views based on the retrieved visibility matrices; determining a displaying order based on the retrieved visibility matrices; and displaying the plurality of selected displayed views via the display of the AR device or another display of another AR device in the determined order, wherein the selected displayed views are displayed simultaneously and/or successively. storing a visibility matrix associated with the stored displayed view, wherein the visibility matrix comprises at least one visibility matrix element indicative of the visibility of the target object; retrieving a respective visibility matrix for a plurality of previously stored displayed views; selecting a plurality of the stored displayed views based on the retrieved visibility matrices; determining a displaying order based on the retrieved visibility matrices; and displaying the plurality of selected displayed views via the display of the AR device or another display of another AR device in the determined order, wherein the selected displayed views are displayed simultaneously and/or successively. <EOS>
