Systems and methods provide for determining a location and size of a visual link to digital media on physical media such as a paper document. An authoring tool for creating a link on a paper document, such as an Embedded Media Marker (EMM), identifies and scores other EMMs and related keypoints on the document to determine similarities between a newly-created EMM and other EMMs and keypoints on the paper document. The scores are visualized for a user on a display in order to position and size the newly-created EMM in a location on the paper document that will avoid confusion with other EMMs and related content. The location and size of the newly-created EMM may be automatically adjusted based on the scoring of the keypoints and related EMMs.

A method for generating content links between a first digital file and a second digital file by detecting a content feature of a first digital file segment of the first digital file during playback of the first digital file segment of the first digital file, searching an index of a plurality of content features for a plurality of segments including a second digital file segment of the second digital file, and dynamically generating a link between the first digital file one segment of the first digital file and the second digital file segment of the second digital file when a content feature of the first digital file segment of the first digital file is related to the content feature of the at least one segment of the second digital file.

Embedded Media Markers (EMM) are optical-filter-like overlaid marks that can be printed on a part of a paper document that signify the existence of media associated with that part of the document. Users take a picture of an EMM-signified document patch using a cell phone camera, and the media associated with the EMM-signified document location is retrieved and displayed on the phone. Unlike bar codes, EMMs are nearly transparent and thus do not interfere with the document contents. Retrieval of media associated with an EMM is based on image local features of the captured EMM-signified document patch. A semi-automatically technique places an EMM at a location in a document, in such a way that the EMM encompasses sufficient identification features with minimal disturbance to the original document.

Embedded Media Barcode Links (EMBL), are optimally blended iconic barcode marks printed on paper documents that signify the existence of media associated with that part of the document. EMBLs are used for media retrieval with a camera phone. Users take a picture of an EMBL-signified document patch using a cell phone, and the media associated with the EMBL-signified document location is displayed on the phone. Unlike traditional bar code which requires an exclusive space, EMBLs are optimally blended with contents and thus have less interference with the original document layout and can be moved closer to a media associated location. Unlike Embedded Media Makers (EMM) which requires underlying document features for the marker identification, EMBL has no requirement to underlying features. Moreover, EMBL can take the advantage of users' knowledge to traditional barcode. Retrieval of media associated with an EMBL is based on the barcode identification of the captured EMBL.

An audio device management system (ADMS) manages remote audio devices via user selections in video links. The system enhances audio acquisition quality by receiving and processing human suggestions, forming customized two-way audio links according to user requests, and learning audio pickup strategies and camera management strategies from user operations. The ADMS control interface for a remote user provides a multi-window GUI that provides an overview window and selection display window. The ADMS provides users with more flexibility to enhance audio signals according to their needs and makes it more convenient to form customized two-way audio links without requiring users to remember a list of phone numbers. The ADMS also automatically manages available microphones for audio pickup based on microphone sound quality and the system's past experience when users monitor a structured audio environment without explicitly expressing their attentions in the video window.

Methods and apparatuses for identifying an image based on Embedded Media Marker (EMM) identification. A hierarchal comparison including a first coarse comparison and a second refining comparison is used. The first coarse comparison compares an image with an EMM to images in a database at a low resolution. The results are fed to the second refining comparison, which conducts a comparison at a higher resolution than the first coarse comparison. By utilizing this hierarchical comparison approach, it is possible to identify the image with fewer false positives.

The present invention provides a paper-based meeting service management tool for meeting support functions. The paper-based tool includes a digital pen that can be used to make strokes which can be transmitted from the digital pen to services that provide the meeting support functions. The paper-based tool also includes digital paper that has an underlying image pattern. The digital pen can locate itself on the digital paper by recognizing underlying dot patterns and transmitting the location information to a computer through a Bluetooth connection.

Systems and methods provide for mixed use of physical documents and a computer, and more specifically provide for detailed interactions with fine-grained content of physical documents that are integrated with operations on a computer to provide for improved user interactions between the physical documents and the computer. The system includes a camera which processes the physical documents and detects gestures made by a user with respect to the physical documents, a projector which provides visual feedback on the physical document, and a computer with a display to coordinate the interactions of the user with the computer and the interactions of the user with the physical document. The system, which can be portable, is capable of detecting interactions with fine-grained content of the physical document and translating interactions at the physical document with the computer display, and vice versa.
