Abstract: A computer-implemented method is for identifying the presence of an image trigger in a digitally captured scene. The method includes, at a component installed on a client device and upon commencement of an image trigger matching operation: a) obtaining, from a multiplicity of image triggers, a subset of image triggers; b) subdividing the subset of image triggers into a plurality of image trigger sub-subsets; and c) for each sub-subset of image triggers in turn, and at predefined time intervals, submitting the sub-subset of image triggers to an Augmented Reality (AR) core Application Programming Interface (API), to cause the client device to cache the received sub-subsets of image triggers, search the digitally captured scene for the presence of one or more of the cached image triggers, and identify a positive match of an image trigger to said component using said AR core API.

Abstract: A method comprises: obtaining content, a content location search term, and an image trigger; submitting the content location search term to a web mapping service so that a service API searches with the content location search term; receiving content locations corresponding to the content; adding the content, image trigger, and content locations to a distribution database that is searchable by location; receiving from a consumer device a location of the consumer device; searching the database using the location of the consumer device to identify any content having content locations that correspond to the consumer device's location, and obtaining the associated image trigger(s); performing an image recognition process on image data captured by the consumer device to identify the presence of the or each said associated image trigger in the image data; and if the presence of any of the image triggers is detected, serving the content to the consumer device.

Abstract: A computer-implemented method of distributing location-based message contents over a messaging system comprises, for each message of a set of messages, obtaining a message content, defining for the message a multiplicity of message locations, and adding the message content and the defined locations to a message distribution database or set of linked databases that is or are searchable by location. The method further comprises receiving from a consumer device a consumer update request including a location of the consumer device or a consumer defined location, searching the database using the consumer device location or consumer defined location to identify, for each of one or more of said messages, a single message location that is within a first predefined range of the consumer device location or consumer defined location and/or that is closest to the consumer location or consumer defined location, and sending the identified message location(s) to the consumer device.

Abstract: A computer-implemented method of distributing location-based message contents over a messaging system and that are displayable on consumer devices present at associated locations. The method comprises, for each message of a set of messages, obtaining a message content, defining for the message a multiplicity of message locations, and adding the message content and the defined locations to a message distribution database or set of linked databases that is or are searchable by location.
