Abstract: An information processing apparatus includes a determination unit configured to determine a playback mode of sound included in content. The information processing apparatus includes a playback unit configured to play back the sound included in the content in the playback mode determined by the determination unit, at playback of the content.

Abstract: An information processing apparatus includes a learning unit which learns sound level manipulation relating to a sound level of a terminal device used by a user based on information relating to the user. The information processing apparatus includes a determination unit which determines a reproduction mode at the time when the terminal device reproduces an audio contained in a content according to a learning result of the learning unit. The information processing apparatus includes a controller which controls an audio contained in the content in the reproduction mode determined by the determination unit.

Abstract: An agent interface device provides information suited for user preferences on the basis of a usage history. In an example implementation, the agent interface device controls the display and action of the agent. A user preference database stores user preferences. An information providing engine provides information to the user according to information in the preference database, and a timer sets a time for the information providing engine to provide information to the user.

Abstract: An example window display device on a window-system type computer system displays a main window and a sub-window. The window display device includes a sub-window moving mechanism for moving the sub-window in accordance with movement of the main window so that the sub-window may always keep a specified relative position with respect to the main window on a display screen.

Abstract: An agent interface device for providing information suited for user preferences on the basis of the user usage history.

Abstract: An on-demand interface device comprises a voice input means for voice-inputting a retrieval request and instruction by a user, a request text input means for inputting the request and instruction by text, an input starting means for informing a control means of starting input operation, a voice recognizing means for recognizing an input speech, a control means for controlling the on-demand interface device, a selecting means for selecting a user's desired one from the results output by an output means, an output means for outputting a result of retrieval from a function database, an impersonated character image and a speech of the character, a function database containing scripts of help descriptions and instructions, a fail-in-retrieval response database containing massages to be output to the output means if a retrieval result is zero and scripts of actions of the character, and a command database containing commands to instruct the control means.

Abstract: An agent interface controls display of an agent and receives a request from a user. A search engine searches for an action script describing a procedure of controlling the agent interface in accordance with the request input from the agent interface. An action script executing engine executes the action script searched by the search engine. Thus, since action scripts adapted to be used for the same kind but different types of electrical household appliances are prepared in action script DB, for example, the different types of electrical household appliances can be operated by the same procedure and interfaces can be unified.

Abstract: A retrieval apparatus is capable of simultaneously executing keyword retrieval and semantic retrieval of information.

Abstract: The present invention is intended to provide an on-demand interface device which is capable of retrieving a function corresponding in meaning to an inputted request sentence and easily executing the retrieved function. The on-demand interface device comprises a function-description database containing function-descriptive sentences for respective functional items and action scripts for realizing respective functions, retrieving means for retrieving a functional item corresponding to a requesting sentence inputted through an input means, script executing means for realizing the retrieved function by executing a corresponding script. The retrieving means can conduct the retrieval of keywords as well as the retrieval of a requesting function by determining an inner product of two sentence vectors, i.e., of a request and each of function-descriptions for respective functional items.
