Abstract: A system for automatically tracking movement of a user participating in a video chat application executing in a computing device is disclosed. A capture device connected to the computing device captures a user in a field of view of the capture device and identifies a sub-frame of pixels identifying a position of the head, neck and shoulders of the user in a capture frame of a capture area. The sub-frame of pixels is displayed to a remote user at a remote computing system who is participating in the video chat application with the user. The capture device automatically tracks the position of the head, neck and shoulders of the user as the user moves to a next location within the capture area. A next sub-frame of pixels identifying a position of the head, neck and shoulders of the user in the next location is identified and displayed to the remote user at the remote computing device.

Abstract: Systems and methods for sharing personalizable cards via a computerized card service are provided. One disclosed method includes, at a card client program executable on a computing device, creating a personalizable card having extensible data, and sending a first instance of the personalizable card to a card service program. The method may further include, at the card service program, propagating the first instance of the personalizable card to a peer of the user, and at the card client program, updating the extensible data of the personalizable card. Upon updating the extensible data, the method may further include sending a second instance of the personalizable card to the card service program, and propagating the second instance of the personalizable card to the peer of the user. The personalizable card may be propagated according to propagation permissions set by the user.

Abstract: Methods, systems, and computer program products for maintaining current contact and metadata information for one or more contacts. A mobile phone stores contact information for multiple forms of mobile phone communication with the contacts. Each contact is identified as either an automatic live contact to be synchronized as new information becomes available or as another contact that will not be synchronized as new information becomes available. The mobile phone communicates the contacts to a data service provider for backup storage and update processing. From automatic contact and metadata information updates initiated by and received from the data service provider the mobile phone periodically updates automatic live contacts. Based on the synchronized contact and metadata information, the mobile phone initiates communication with one of the contacts.

Abstract: A programming object can comprise an executable method for loading a state of the object and an executable method for saving the object's state. The programming object can be an instance of a programmer-defined class. The executable method of the object for loading the state of the object can load the object's state as markup language text, and the executable method of the object for saving the object's state can save the object's state as markup language text.
