A remote assistance workstation configured for being operatively coupled to a portable device that comprises at least a pair of stereoscopic augmented reality glasses, the portable device for use by a first responder to carry out at least one action using a first object at a scene in connection with at least one of (i) a subject and (ii) a second object at the scene, the remote assistance workstation comprising: a communications module, configured for communicating with the portable device in response to a remote assistance request initiated from the portable device; the remote assistance request including at least a live video stream captured via a camera of the stereoscopic augmented reality glasses at the scene; a user interface module configured for (a) rendering a remote assistant graphical user interface on a display device and (b) receiving remote assistant inputs from a remote assistant, wherein the remote assistant graphical user interface includes at least (i) a first pane for displaying the live video stream of the remote assistance request, and (ii) a second pane for displaying a 2D representation of the first object at the scene, wherein the rendered 2D representation is moveable within the second pane in response to one or more remote assistant inputs, the remote assistant graphical user interface further for rendering within the first pane at least one item of 3D virtual content that corresponds to the rendered 2D representation of the first object at the scene within the second pane, relative to at least a reference point within the first pane, wherein the reference point is based upon a content of the live video stream; and a controller for generating one or more remote assistance signals to be output, via the communications module, to the portable device for displaying, in response to the one or more remote assistant inputs moving the rendered 2D representation of the first object at the scene within the second pane, the at least one item of 3D virtual content on the stereoscopic augmented reality glasses to the first responder within a live view of the scene as is captured by the camera of the stereoscopic augmented reality glasses, such that the at least one 3D item of virtual content appears at a correct location with respect to the reference point within the live view for assisting the first responder to carry out the at least one action using the first object in connection with the subject or the second object at the scene. a communications module, configured for communicating with the portable device in response to a remote assistance request initiated from the portable device;
