Abstract: An operation sequence user adaptive system for use in a processing system. The system including a central processing unit in which after objects displayed on a display screen of a display are specified from a mouse or a keyboard, and when a function to be effected for the objects are specified through selection of a function selective menu, a pertinent function of an application program is executed. The adaptive system includes a function of storing a data structure for storing therein a usage frequency of each of the functions, an update function of monitoring an operation conducted by the user for each function and updating a weight between particular functions successively operated, and a combining function of combining, when the weight updated by the update function exceeds a predetermined threshold value, the particular functions associated with the weight.

Abstract: A user adaptive system in a computer system executing an application program. The user adaptive system includes a storage area for storing therein a data structure corresponding to a combination of values for parameters to be arbitrarily set by a user for a job to be executed in the application program, a storage area for updating the combination of values in the structure, each time a parameter setting operation is conducted by the user, and a storage area operative, when a particular combination of values for the parameters is used more than a predetermined number of times, for registering the particular combination of values for the parameters.

Abstract: A user information management device exploits the contents of all communications as information about an individual user, to allow the system to access and update information about the user without modifying the overall system. The system includes a task execution device and a user interface device which interact to perform a task as directed by a user by message communication through a shared medium. The system includes a user information management device and a reference table which includes message patterns for accessing and updating the information about the user and for launching access and update procedures corresponding to a matched pattern.

Abstract: An information processor, which manages operational history data or status data to revert an application back to any desired point in the past or make use of the past operations, includes an interface screen having cards thereon, as objects, that are manipulated by a user so as to make use of history. Contents of the history are represented while the order of the cards, placed one upon another, is associated with the time series of the history. A card representation is provided on the screen presented by the application to the user at any point in a past or to provide a card representation defined by images which alternately display screen representations before and after a change in the application screen by the operation performed by the user at any point in the past, while the before-change and after-change representations are displayed for different periods of time.

Abstract: With the purpose of automatically and efficiently finding and selecting a collection of software functions truly useful for a user from a collection of software functions and of adequately and easily judging whether the software function selected by the user should be adopted or not, the computer system according to the present invention comprises task description holding means for holding a collection of task descriptions formally describing individual utilization patterns of various types of software functions, and filtering means for finding and selecting a task description describing a utilization pattern, not tried by the user in the past and regarded as useful for the user, from a collection of task descriptions held by said task description holding means and for disclosing it to the user. By adding the task description selected by the filtering means to a task model, said task model can be changed during task execution.
