A group working system includes a plurality of work stations interconnected through a network and each having a multi-window function. Each work station is provided with a group working user interface program executed under the control of a control program for transferring control information for a group work with the other work stations. When input operation is performed for a window of a group working mode in any one of the work stations, indication information for identifying an operator or work station performing the input operation is output to an additional window which is paired with the above-mentioned window. By making reference to the indication information, each user can avoid conflict in the input operation to the same window of the group working mode with other users.

A conference system is formed by multiple workstations which have individual conference control programs and are connected to a network, with each workstation having a destination workstation determined in advance so that a ring-shaped logical communication path is formed on the network. A conference control program which detects a fault on its receiving path during a conference sends a fault recovery request message including an identifier of the conference control program itself and the address of the workstation to the neighboring workstation, and the conference control program of the neighboring workstation relays the received fault recovery request message to the next workstation on the ring-shaped logical communication path so that the fault recovery request message is propagated on the ring-shaped logical communication path. The conference control program of a workstation which is located immediately upstream of the fault and is therefore unable to send the received fault recovery request message to the neighboring workstation carries out a procedure of establishing a new communication path to the conference control program of the workstation which issued the fault recovery request message.

In a collaborative information processing system including a plurality of terminals each having a multiwindow function and each being connected to the other terminal via a network, each terminal includes a plurality of application programs for issuing a request for an input event and a request for a window, a window server for converting input data received from the input device into a logical input event and for updating an image on a display screen depending on the content of an output request received from the application program, a plurality of window library modules connected to the window server via a logical communication path and linked with the application programs, and a control program for communicating an input event with other terminals via the network. Each window library module linked with an application program in a collaborative operation mode transfers an input event received from the window server to the control program and delivers an input event received from the control program to the application program to which it is linked therewith.

In a conferencing system including a plurality of workstations each having a multiwindow function connected to each other via a network, programs loaded in the respective workstations to control a conference are linked with each other through a logical circular control program's path. A data item inputted from a workstation not having a data effectuation floor qualification is transmitted as a data item in an ineffective state to a next workstation. When received by a workstation possessing the effectuation floor qualification, the data in the ineffective state is converted into an effective data. In each station, application programs and utility programs are responsive only to the data in the effective state, which guarantees the identity of results of data processing achieved in the respective workstations.
摘要:
A collaborative information processing system is formed of a plurality of terminal units interconnected through a network. Each terminal unit includes a microprocessor provided with a control program for controlling the execution of various application programs and the communication with other terminal units, input/output devices such as a display unit with a display screen and keyboard, and a telephone set. A plurality of users join in a conference or such a group work to create materials by making reference to a material which is displayed equally on the screen of each terminal unit and making conversation through the telephone set under control of the control program. Records of group work information including the outline of the group work, names of participants, and names of materials and data created or referenced during the group work or conference are stored automatically in a database so that the records can readily be retrieved in the future.
摘要:
A system including a plurality of terminal apparatuses connected to each other via a communication network for achieving joint information processing, such as involved in an electronic joint project and an electronic meeting. The terminal apparatuses are interconnected to each other via a logical ring path formed on the communication network. Each terminal apparatus is loaded with a control program for supervising the joint information processing. Each control program functions in cooperation with control programs of other terminal apparatuses to conduct communication procedures for establishing, for changing, or for terminating the logical ring path and to control a display operation to supply the user with information identifying those members currently participating in the joint information processing.
摘要:
There are provided a plurality of units for detecting a moving object in an image from changes of an image structure in a monitor area defined in a linear strip on a single straight line consisting of a base line and its partitions, and a height of a moving object is detected and measured easily and accurately from a code obtained from detection results obtained when the image structure is at its maximum variation.
摘要:
A system infrastructure structure formulation supporting method in which based on quality requirements, formulated examples of system infrastructure structures up to the present are grouped into a database for storing the system infrastructure structures, then being stored into a group management area in advance. At the time of a new formulation, demands presented with an expression which user uses are accepted from an input/output terminal. Then, the demands are converted into quality requirements of the system by making reference to a demand-contents management table, a quality-requirement management table, and a demand-quality-requirement correspondence table stored in a reference information storage area. Next, using the quality requirements acquired, a group stored in the group management area is selected. Moreover, elements within the group are selected from a grouping table, then sequentially presenting the formulated examples having high degrees of similarity.
