1. A method for interacting with a user wearing an augmented reality (AR) device, comprising: detecting by the AR device that the user is in a first state; capturing by the AR device a low resolution frame of a field of view of the user in response to said detecting of the first state; determining from the low resolution frame an image target, wherein the image target has a linked AR content; alerting the user that the image target is available; receiving by the AR device a command from the user on whether to interact with the linked AR content; capturing by the AR device a full resolution frame of the field of view of the user if the command indicates the user wants to interact with the linked AR content; and displaying by the AR device the linked AR content to the user.
