Abstract
A shared window of the same content is displayed on each display device of a plurality of computers connected through a communication network for use in a collaborative work and objects are displayed on the window. Each object is displayed based on object management data having a plurality of types of attributes set therein and the shared windows on which the objects are displayed are limited by the attribute values of the attributes. Further, participants of the collaborative work who are permitted to erase the objects are limited by the settings of the attribute values of the attributes.
Claims23
A collaborative work support system including a plurality of computers each having a display device connected through a communication network, comprising:
- means for displaying a shared window on each display device of each of said computers;
- means for accepting an entry of an object from a user of one of said computers and accepting an attribute for designating a user or a group of users as a display attribute of the object, said display attribute restricting the display of said object to the designated user or group of users;
- and
- display control means for displaying said object on the shared window displayed on the display device of said one computer and displaying said object on the shared window on each of the display devices of the computers used by the user or group of users designated by the display attribute.
A collaborative work support system including a plurality of computers each having a display device connected through a communication network, comprising:
- means for displaying a shared window on each display device of each of said computers;
- means for accepting an entry of an object from a user of one of said computers and accepting an attribute for designating a user or a group of users as an operation attribute of the object, said operation attribute restricting an effective range of an operation to said object within the designated user or the users belonging to the designated group;
- means for displaying the object on each shared window displayed on said display device of each of said computers;
- and
- operation means for accepting an operation entry of the object displayed on the shared window displayed on the display device of an arbitrary computer by the user of said arbitrary computer and applying the accepted operation to the object;
- said operation means accepting the operation of the object only when the user entering the operation is the user or one of the users belonging to the group of users designated by the operation attribute.
A collaborative work support system including a plurality of computers each having a display device connected through a communication network, comprising:
- means for displaying a shared window on each display device of each of said computers;
- means for accepting an entry of object from a user of one of said computers and accepting first information for designating a user or a group of users as a display attribute of the accepted object entry and also accepting second information for designating a user or a group of users as an operation attribute of the accepted object entry;
- display control means for displaying an object accepted in said one computer on the shared window displayed on the display device of said one computer and displaying said object on the display devices of the computers used by the user or the users belonging to the group of users designated by the display attribute of the object;
- and
- operation means for accepting an operation entry of the object displayed on the shared window displayed on the display device of said one computer by the user of said one computer and applying the accepted operation to the object;
- said operation means accepting the operation of the object only when the user entering the operation is the user or the users belonging to the group of users designated by the operation attribute of the object.
A collaborative work support system for displaying shared windows on display devices of a plurality of computers connected through a communication network, each of said computers comprising:
- means for storing object management data for determining a plurality of attributes for each of objects to be displayed on said shared windows;
- and
- means for displaying the object on the shared windows displayed on the associated display devices in accordance with the object management data;
- at least one attribute of the object in said object management data including an attribute value to limit an effective range of the attribute to a group of computers within said plurality of computers.
