Abstract: A method for determining an emotional state of a subject taking an assessment. The method includes eliciting predicted facial expressions from a subject administered questions each intended to elicit a certain facial expression that conveys a baseline characteristic of the subject; receiving a video sequence capturing the subject answering the questions; determining an observable physical behavior experienced by the subject across a series of frames corresponding to the sample question; associating the observed behavior with the emotional state that corresponds with the facial expression; and training a classifier using the associations. The method includes receiving a second video sequence capturing the subject during an assessment and applying features extracted from the second image data to the classifier for determining the emotional state of the subject in response to an assessment item administered during the assessment.

Abstract: The present disclosure relates to games and applications in general and in particular to computer-implemented online games, such as online role-playing games, playable by more than one person from more than one location.

Abstract: Methods, systems, and computer programs are presented for limiting transfer of virtual currency in an online game. One method includes an operation for receiving, at a server, a purchase order for virtual currency from a first player. The purchase order is made with legal currency, and the virtual currency is usable within a computer-implemented gambling game. Further, the method includes operations for crediting an account of the first player with virtual currency, and for enabling the first player to make transfers of the virtual currency to other players. The transfers of virtual currency from the first player to other players are then limited, such as by limiting the amount, the frequency, or the recipients of the transfers.

Abstract: A method, data processing system, and computer program product for locating people. A mobile data processing system identifies a number of degrees of separation from a requestor for use in searching for the people. The mobile data processing system searches a network data processing system for data structures that contain information about associations between the people that are within the number of degrees of separation from the requestor to generate an initial group of people. The mobile network data processing system identifies a group of people from the initial group of people that are within a geographic location based on a location of the mobile data processing system and a portion of the group of people who are online. The mobile data processing system displays the portion of the group of people on a display device for the mobile data processing system.

Abstract: A physical security system having multiple server nodes may be built as a distributed network. To send data between the nodes in the network, a first node may access a node identifier identifying a second node, with both the first and second nodes forming at least part of a server cluster, and the first node may then send the data to the second node. The node identifier forms at least part of cluster membership information identifying all and accessible by all server nodes in that server cluster. Functionality such as the ability to share views between system users and the ability for those users to control an unattended display may be implemented on a distributed network, a federated network, or another type of network.
