Embodiment Construction

[0020] Embodiments related to augmented reality environments are disclosed in the context of mobile computing. AR authoring tools accessible via mobile devices enable mobile device users to define an AR environment and deploy media such as images, video, animation, text, and audio, including photographs or other graphical elements, within the AR environment content. Media content deployed by a particular mobile device user can be accessed by other mobile device users exploring the augmented reality environment via their respective mobile devices.

[0021] Target objects such as magazine advertisements, bulletin boards, documents and other real world 2D and 3D objects are captured in the mobile device's AR view mode. The augmented reality information may be determined, for example, by applying object recognition techniques to obtain an electronic representation of the target object. This electronic representation may include a number of (key) points and their associated descr...

Abstract

The present invention provides methods, apparatuses and systems to translate 3D spatial information detected in an augmented reality AR view of a mobile device into screen alignment information on the mobile device. In at least one embodiment, a method comprises: determining augmented information associated with an object of interest, including a model-view (M1) matrix and a projection (P1) matrix; displaying the augmented information on top of the video image of the subject; generating a second model-view (M2) matrix and a second projection (P2) matrix such that the matrices M2 and P2 represent the screen alignment of the augmented information in the final position; and displaying the amplification information using the M2 and P2 matrices.

Description

technical field [0001] The subject matter disclosed herein relates to electronic devices, and more particularly to methods, apparatus, and systems for use in and / or with augmented reality (AR) environments for mobile electronic devices . Background technique [0002] Mobile computing devices (mobile devices) provide users with access to a variety of information via wireless communication systems. As an example, mobile devices capable of working with wireless cellular networks and / or wireless local area networks (eg, Wi-Fi or WiMAX) provide users with access to the vast information resources of the Internet. Mobile devices may also enable users to explore augmented reality environments that provide real-time views of target objects merged with or augmented by computer-generated graphical content. For example, an on-board camera resident on a mobile device can be used in conjunction with a graphical display to present the user with supplemental information about a target of ...
