摘要： Within a social network, users may form social groups based on shared traits, such as experiences and interests. The social network may be able to detect a user interest among the users of a social group in one or more products offered by one or more vendors (e.g., by evaluating conversations within the social group and search queries executed by users of the social group), and to notify the vendors of the detected user interest. The vendors may be willing to extend an offer to the users of the social group regarding the product, and the social network may present the offer to the users of the social group. The social network may also track acceptances of the offer by users of the social group, and may provide an e-commerce infrastructure to allow users to complete purchases of the product and to provide the rewards featured in the offers.

摘要： A system and process for providing progressively higher quality versions of an audio and/or video program over a client-server based network. In response to a user command to view a particular program, the client requests layered data associated with the program from the server. The client also specifies how many consecutive layers are to be transmitted based on the bandwidth available on the network. The client then receives the data from the server, caches it, renders it as it is received, and presents it to the viewer. Upon a request from the user for a higher quality version of the program, the client requests as many enhancement layers associated with the program as possible given the available bandwidth. The client receives the requested data, combines it with the previously stored lower-level layer data, renders the higher quality version of the program, and presents the new version to the user.

摘要： The present invention is embodied in a system and method for automatically adjusting gaze and head pose in a videoconferencing environment, where each participant has a camera and display. The images of participants are rendered in a virtual 3D space. Head-pose orientation and eye-gaze direction are corrected so that a participant's image in the 3D space appears to appear to be looking at the person they are looking at on the screen. If a participant is looking at the viewer, their gaze is set toward the “camera”, which gives the perception of eye-contact.
