Abstract: An information processing apparatus and method configured to display content in a content display screen area, which is at least one of a plurality of screen areas, displayed. The information processing apparatus includes an event detector configured to detect generation of a predetermined event concerning a content, a notifying unit configured to notify a user of the information processing apparatus of the detection of the predetermined event upon detecting the predetermined event, a work concentration state detector configured to determine whether the user is in a work concentration state, and an inhibiting unit configured to inhibit the notifying unit from notifying the user of the detection of the predetermined event upon determining the work concentration state of the user.

Abstract: There is provided a preference data generation device for generating preference data of a viewer pertinent to content to be displayed in a content display screen area that is one of a plurality of screen areas displayed on a display unit in an information processing system apparatus provided with the display unit, the device including a state information acquisition unit that acquires state information pertinent to the plurality of screen areas displayed on the display unit; a preference evaluation value calculation unit that calculates a preference evaluation value pertinent to the content, based on the state information acquired by the state information acquisition unit; and a preference data generation unit that generates preference data pertinent to the content, based on the preference evaluation value calculated by the preference evaluation value calculation unit.

Abstract: A device for executing a main program written in an interpreter language includes a processing unit for executing a program written in the interpreter language and a monitor program which is written in the interpreter language for monitoring the execution of the main program. The device further includes a first switching unit for switching the processing unit from executing the main program to executing the monitor program after an execution of one execution unit of the main program, and a second switching unit for switching the processing unit from executing the monitor program to executing the main program after an execution of the monitor program.
