Abstract

A collaborative work support system that is performed on plural computers each of which is assigned for an operator, and supports collaborative work in which the plural computers display common data and each operator operates the displayed common data through his own computer. The collaborative work support system includes: a shared data storage for storing shared data to be displayed on each computer; an individual data storage for storing individual data, which is individually created by a specific operator and individually displayed on any of the computers; an individual data sender for sending the individual data to other computers in response to a command from the specific operator who created the individual data so as to display the individual data on other computers as created shared data; and a manager for managing so that the individual data is stored in the shared data storage with other data associated with the individual data as a unit of storage.

Claims

1. A collaborative work support system that supports collaborative work on a plurality of computers that are connected with each other and each of which is assigned for an operator and displays shared data, and each operator can change the displayed shared data on his own computer while other computers display the shared data, comprising:

shared data storage means for storing shared data to be displayed on each computer;

individual data storage means for storing individual data, which is individually created by a specific operator and individually displayed on any of the computers;

individual data sending means for sending the individual data to other computers in response to a command from the specific operator who created the individual data so as to display the individual data on other computers as created shared data;

management means for managing so that the individual data is stored in said shared data storage means with other data associated with the individual data as a unit of storage; and

associating means for associating a plurality of units of storage with each other based on attributes regarding an association therebetween.

2. The collaborative work support system as set forth in claim 1, wherein each computer further comprises:

mode selecting means for selecting either a synchronous mode or a asynchronous mode of the computer;

the synchronous mode is the mode when the computer receives input data from the operator or receives data from other computers, the computer displays the input data or the data from the other computers, sends the input data to other computers, and stores the input data or the data from the other computers into said shared data storage means; and

the asynchronous mode is the mode when the computer receives input data from the operator, the computer individually displays the input data and stores the input data into the individual data storage means.

3. The collaborative work support system as set forth in claim 2, wherein each computer further comprises:

permission getting means for getting permission for the computer to change the shared data; and

said mode selecting means assigning the asynchronous mode to the computer, when the computer receives input data from the operator while the computer does not have the permission.

4. The collaborative work support system as set forth in claim 2, each computer further comprising:

automatic recovering means for controlling said mode selecting means to assign the synchronous mode to the computer, when a prescribed time lapses on the asynchronous mode after the operator stops inputting data.

5. The collaborative work support system as set forth in claim 2, each computer further comprising:

permission getting means for getting permission for the computer to change the shared data either before or after said individual data sending means sends the individual data;

said mode selecting means assigning the synchronous mode to the computer after said permission getting means gets the permission.

6. The collaborative work support system as set forth in claim 2, each computer further comprising:

permission getting means for getting permission for the computer to change the shared data either before or after said individual data sending means sends the individual data; and

said individual data sending means sending the individual data when said permission getting means get the permission.

7. The collaborative work support system as set forth in claim 1, further comprising:

display control means for determining whether each unit of storage should be displayed or not.

8. The collaborative work support system as set forth in claim 1, further comprising:

display control means for displaying a page, which includes a set of layers overlapping with each other, each of the layers corresponding to each unit of storage.

9. The collaborative work support system as set forth in claim 8, further comprising:

page creation means for specifying a plurality of layers, and for creating a page from the specified set of the layers.

10. The collaborative work support system as set forth in claim 8, further comprising:

layer selecting means for selecting a layer to be displayed on each computer for operating.

11. The collaborative work support system as set forth in claim 1, further comprising:

data integrating means for selecting a plurality of the units of storage, and integrating the selected units of storage into a new unit of storage.

12. The collaborative work support system as set forth in claim 1, further comprising:

visualizing means for displaying a plurality of layers, each of which is corresponding to each unit of storage, arranged in the order of created date of each layer.

13. The collaborative work support system as set forth in claim 1, further comprising:

visualizing means for displaying a plurality of layers, each of which is corresponding to each unit of storage, arranged according to the attributes provided by said associating means.

14. The collaborative work support system as set forth in claim 1, further comprising:

said management means managing the shared data by associating each unit of storage with data of time when each unit of storage is being displayed;

multimedia data record/playback means for storing multimedia data regarding the collaborative work from when the collaborative work started; and

multimedia data playback instruction means for instructing said multimedia data record/playback means to play back the multimedia data corresponding to the unit of storage according to the data of time associated with the unit of storage by said management means.

15. A method for managing data for collaborative work on a plurality of computers that are connected with each other and each of which is assigned for an operator and displays shared data, and each operator can change the displayed shared data on his own computer while other computers display the shared data, comprising the steps of:

receiving individual data, which is individually created by a specific operator and individually displayed on any of the computers;

sending the individual data to other computers in response to a command from the specific operator who created the individual data so as to display the individual data on other computers as created shared data;

managing so that the individual data is stored in said shared data storage means with other data associated with the individual data as a unit of storage; and

associating a plurality of units of storage with each other based on attributes regarding an association therebetween.
