Abstract: Systems and techniques are described for path selection. A packet can be transparently intercepted at an intermediary device. Next, the intermediary device may modify one or more bits in the header of the packet. The intermediary device can then forward the packet to the next hop device. In some network configurations, the modifications to the one or more bits in the header of the packet may cause a downstream device to select a path that is different from the path that would have been selected by the downstream device if the one or more bits in the header of the packet had not been modified. A path selection policy can be used to determine whether or not one or more bits in the header of the packet are to be modified.

Abstract: A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image.

Abstract: A single device that receives communications intended for a user having multiple contact addresses associated with different user roles is provided. The single device can receive communications intended for multiple telephone numbers, email aliases, screen names, aliases, other means of contact, or combinations thereof. Since a user engaged in a particular role might not desire to be interrupted with communications intended for a different role, the communications for the other roles can be maintained until the user is actively engaged in the role for which the communication was intended. In situations where there is an important communication sent to a non-active role, selective convergence between roles is initiated and the important communication is presented to the user.

Abstract: Recording of various events in a video format that facilitates viewing and selective editing are provided. The video can be presented in a wiki-format that allows a multitude of subsequent users to add, modify and/or delete content to the original recorded event or a revision of that event. As edits and annotations are applied, either automatically or manually, such edits can be indexed based on criteria such as identification of an annotator, a time stamp associated with the edit, a revision number, or combinations thereof. The edits or annotations can be provided in various formats including video, audio, text, and so forth.

Abstract: A single device that receives communications, resources, data, and/or other information intended for a user having multiple contact addresses is provided. The single device can receive various information intended for multiple telephone numbers, email aliases, screen names, aliases, other means of contact, or combinations thereof. The device can selectively forward the information to the user based on a current user role, user preferences, contact information, or based on other criteria. If information is to be forwarded to the user at substantially the same time as receipt, automatic means of notifying the user of the role for which the communication is intended are provided.

Abstract: A facility is described for providing conference roll calls that identify participants in electronically facilitated conferences. In various embodiments, the facility receives identifiers of participants in an electronically facilitated conference and displays a list of the participants in a roll call. The list can include indications of which participant is speaking, whether participants are authenticated, and other information associated with the participant, such as the participant's name.

Abstract: A facility allows for automatic delegation of incoming real-time communications based on a delegation scheme. The delegation scheme may be rules-based and may be applied to a single real-time communication channel or multiple communication channels, including both real-time and non-real-time communication channels. The delegate information may include rules that indicate under what circumstances a communication should be rerouted, which delegate the communication should be rerouted to, and whether other associated actions should be taken in connection with the rerouting (or lack thereof). In some cases, the context of the incoming communication may play a role in how or whether a communication is rerouted to a delegate.

Abstract: A stylus for use as an input device automatically switches its mode of operation.

Abstract: Systems, methods, and computer-readable storage media are provided for conducting searches utilizing search navigation patterns. Search queries are received that include search terms that are of a particular type. It is recognized that at least one prior search session has been conducted that included a search query having search terms of an equivalent or similar type and followed a particular navigation pattern. Such prior search(es) may have been conducted by the user or by a different user and/or may have a navigation pattern that was affirmatively recorded by the requesting user or that was recorded by the system without explicit contemporaneous user instruction to do so. Upon identifying the navigation pattern associated with the prior search, the system effectively conducts a search session following the navigation pattern.

Abstract: An electronic device may include a touch screen electronic display configured to offset and/or shift the contact locations of touch implements and/or displayed content based on one or more calculated parallax values. The parallax values may be associated with the viewing angle of an operator relative to the display of the electronic device. In various embodiments, the parallax value(s) may be calculated using three-dimensional location sensors, an angle of inclination of a touch implement, and/or one or more displayed calibration objects. Parallax values may be utilized to remap contact locations by a touch implement, shift and/or offset displayed content, and/or perform other transformations as described herein. A stereoscopically displayed content may be offset such that a default display plane is coplanar with a touch surface rather than a display surface. Contacts by a finger may be remapped using portions of the contact region and/or a centroid of the contact region.

Abstract: Architecture for completing search queries by using artificial intelligence based schemes to infer search intentions of users. Partial queries are completed dynamically in real time. Additionally, search aliasing can also be employed. Custom tuning can be performed based on at least query inputs in the form of text, graffiti, images, handwriting, voice, audio, and video signals. Natural language processing occurs, along with handwriting recognition and slang recognition. The system includes a classifier that receives a partial query as input, accesses a query database based on contents of the query input, and infers an intended search goal from query information stored on the query database. A query formulation engine receives search information associated with the intended search goal and generates a completed formal query for execution.

Abstract: A bootstrapping technique for wirelessly obtaining white space data that may be used to identify an available white space channel for connecting to a service. Portable wireless devices may collaborate to provide white space data to a device requesting such data. A requesting device transmits a request for the white space data using, for example, an unlicensed band. A device receiving the request may transmit a copy of the data to the requesting device. The transmitted copy may be obtained by the receiving device from a local data store or may be provided from a database server to which the receiving device is connected. In the later case the receiving device acts as a proxy between the database server and the requesting device. Once the white space data is received by the requesting device it may be used to select a channel for communication in the white space.

Abstract: Enhanced telephony computer user interfaces seamlessly integrate and leverage the features of personal computers and telephones. The manner in which media is presented at a computing system can also be modified automatically in response to detected telephone operations. These modifications can include pausing media in response to a detected telephone call and/or adjusting a volume of the media presentation. The media presentation/volume can also be resumed/restored upon detecting that the telephone call has terminated.

Abstract: An enhanced telephony (ET) computer user interface that seamlessly integrates features of a personal computer (PC) and a telephone into a coherent user interface. The user is provided with a rich variety of functionality that leverages the fact that the PC has considerably more processing power and greater access to variety of data than the ordinary telephone. This processing power and data access is used to the user's advantage as the telephone's capabilities and functionality are greatly expanded. Notes and other documents corresponding to a previous call can be identified and presented during a call.

Abstract: A user entering information in an application might desire functionality not supported by that application. Based on an input or a subset of the input, a functionality associated with a different application can be automatically applied within a current application. Sometimes, a particular application or mode of communication can be used to send information and reply information can be sent in a different mode of communication. The communications can be automatically associated or related to each other. A user can be presented with information relating to both communications, upon request, although the communications might be associated with different modes of communication. Constraints or parameters can be placed on a subsequent communication by either a sender or a recipient.
