METHODS AND APPARATUS FOR AUGMENTED REALITY TARGET DETECTION

摘要

Systems and methods are disclosed for target-based AR devices to perform low-power front-end passive scanning of targets to alert users to AR content linked to any image targets the users may be viewing. Passive scanning by AR devices relieves users of the need to manually activate a camera for AR image target identification, and helps to identify image targets the users may be unknowingly viewing. To conserver power, AR devices may autonomously activate a camera to perform an exploratory scan when the AR devices detect from users' movement patterns that users may be interested in certain targets or is in a state of attentiveness. AR devices may identify one or more image targets from the exploratory scans. If users elect to interact with the AR content, AR devices may activate the camera to perform a full capture or real-time tracking of the image targets to augment the AR content.

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.
