Patent attributes
A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). The present invention provides systems, methods, and computer program products for modifying documents for shared use, and for collaborative discussion of shared documents. Captured digital images of documents or portions associated with a user are received, along with modifications to the images. Documents are recognized from the captured digital images, and the modifications to the images are applied to the documents. Alternatively, captured digital images of documents are received, and the documents are recognized along with a hotspot in the document. The user is authenticated to a website associated with the hotspot, and is provided access to an associated multimedia repository.
