Abstract

An information sharing method and apparatus using an object oriented technology are provided for mutually sharing any manipulation events in a shared environment which operates in a plurality of computers on a network. The method provides a plurality of objects to be used by users for information processing on their information processing apparatuses, and an environment in which the objects operate. Each of the objects transmits an event made thereto by an operator as a message. A shared field object is shared by a plurality of users, and one or more objects operate on the shared field object. These objects are distributed to the plurality of users to share the same environment among the users. A message of the event is distributed to each of the users through the shared field object to recall the event in the respective environments to share the operation of the object.

Claims

1. An information sharing method using an object oriented technology, comprising the steps of:

providing a plurality of computers connected to a network with an environment in which visual objects operate, each visual object including a model part having a structure called a slot for holding the state of the visual object itself and a view part for exchanging a message with the model part;

providing a shared field visual object which is operable as an environment of execution of said visual object to be shared and exchanges sharing information of said visual object to be shared with the other shared field visual object;

registering one or more visual objects to be shared in said shared field visual object as required at any arbitrary time;

delivering and loading said shared field visual object and said one or more visual objects to be shared, which are registered as required at any arbitrary time, onto said plurality of computers;

recording, in response to each manipulation made by an operator to said visual object to be shared, event information on said visual object to be shared;

managing said recorded event information for each visual object to be shared as an object scenario;

delivering said object scenario to said shared field visual object on said plurality of computers; and

executing said delivered object scenario for each visual object to be shared associated with said scenario by said shared field visual object on said plurality of computers.

2. The information sharing method using an object oriented technology according to claim 1, wherein:

each of said recorded one or more visual objects to be shared holds information on its position relative to said shared field visual object.

3. The information sharing method using an object oriented technology according to claim 1, wherein:

said object scenario is recorded by said shared field visual object.

4. The information sharing method using an object oriented technology according to claim 1, wherein:

said object scenario is recorded by a visual object to be shared itself which is manipulated by said object scenario.

5. The information sharing method using an object oriented technology according to claim 1, wherein:

said object scenario includes sequential recording of a change in a relative position of a visual object to be shared with respect to said shared field visual object associated with movements of said visual object to be shared, wherein said relative position is recorded at intervals of adjustable sampling time period.

6. The information sharing method using an object oriented technology according to claim 1, wherein:

said shared field visual object holds information on users who share said shared field visual object, and information on a server which has user information, wherein a destination of an object scenario is determined based on such shared information.

7. The information sharing method using an object oriented technology according to claim 1, wherein:

a visual object operating under management of said object scenario cannot be manipulated by individual sharers while an independent visual object not operating under management of said object scenario can be manipulated by the individual sharers.

8. The information sharing method using an object oriented technology according to claim 1, wherein:

said step of delivering and loading said shared field visual object and said one or more visual objects to be shared, which are registered as required at any arbitrary time, onto said plurality of computers and said step of delivering said object scenario to said shared field visual object on said plurality of computers are directly executed mutually by said plurality of computers.

9. The information sharing method using an object oriented technology according to claim 1, wherein:

said step of delivering and loading said shared field visual object and said one or more visual objects to be shared, which are registered as required at any arbitrary time, onto said plurality of computers and said step of delivering said object scenario to said shared field visual object on said plurality of computers are executed through a server computer on the network.

10. The information sharing method using an object oriented technology according to claim 1, wherein:

said step of delivering and loading said shared field visual object and said one or more visual objects to be shared, which are registered as required at any arbitrary time, onto said plurality of computers is executed through a server computer on the network; and

said step of delivering said object scenario to said shared field visual object on said plurality of computers is directly executed mutually by said plurality of computers.

11. A computer readable recording medium having recorded thereon a program which, when executed on a computer, causes the computer to execute a program comprising the steps of:

providing a plurality of computers connected to a network with an environment in which visual objects operate, each visual object including a model part having a structure called a slot for holding the state of the visual object itself and a view part for exchanging a message with the model part;

providing a shared field visual object which is operable as an environment of execution of said visual object to be shared and exchanges sharing information of said visual object to be shared with the other shared field visual object;

registering one or more visual objects to be shared in said shared field visual object as required at any arbitrary time;

delivering and loading said shared field visual object and said one or more visual objects to be shared, which are registered as required at any arbitrary time, onto said plurality of computers;

recording, in response to each manipulation made by an operator to said visual object to be shared, event information on said visual object to be shared;

managing said recorded event information for each visual object as an object to be shared scenario;

delivering said object scenario to said shared field visual object on said plurality of computers; and

executing said delivered object scenario for each visual object to be shared associated with said scenario by said shared field visual object on said plurality of computers.
