Abstract: One embodiment of the present invention provides a system for adjusting a number of game mechanics associated with a game system. During operation, the system obtains a psychosocial profile associated with a user, adjusts the game mechanics based on the obtained psychosocial profile, and updates the game system based on the adjusted game mechanics.

Abstract: One embodiment of the present invention provides a system for recruiting individuals with a desired socio-demographic distribution. During operation, the system receives the desired socio-demographic distribution, obtains a seed sample comprising a plurality of participants, calculates a socio-demographic distribution associated with the seed sample, calculates an incentive provided to a user for recruiting an individual with a desired socio-demographic attribute, and presents the incentive to the user, thereby motivating the user to recruit the individual with the desired socio-demographic attribute.

Abstract: One embodiment of the present invention provides a system that facilitates location-aware, mixed-reality gaming platform. During operation, the system determines a layout of a user's surrounding. The system further detects the user's location and/or nearby objects. Next, the system associates virtual content to the determined layout and associates a set of game rules with the virtual content. Subsequently, the system produces a visual and/or audio representation of a game based on the game rules and virtual content to the user, thereby allowing the user to play a game that corresponds to his surrounding and location.

Abstract: A system facilitates traversing digital records with dimensional attributes. The system stores a number of digital records. The system further associates a respective digital record with a number of attributes, wherein a respective attribute can be specified in a number of levels of abstraction. The system allows a user to control a presentation of the stored digital records based on their attributes. The user can set one or more criteria for the attributes of the digital records to be presented by: specifying the value of at least one fixed attribute of the digital records to be presented, changing at least one non-fixed attribute of the digital records to be presented, and/or specifying a level of abstraction for the fixed and/or non-fixed attribute of the digital records to be presented. The system then presents a set of digital records to the user based on the attribute criteria set by the user.
