Abstract:
A multi-user collaborative system in which the contents as well as the current status of other user activity of a shared structured data object representing one or more related structured data objects in the form of data entries can be concurrently accessed by different users respectively at different workstations connected to a common link.
Independent claims (as numbered):
1. A method for operating a collaborative system that includes a plurality of workstations each having a respective display and a respective user input device, the collaborative system further including shared data, each of the workstations being connected for accessing the shared data, the shared data including a set of parts, the method comprising the steps of:
presenting on the respective display of a first one of the workstations a local representation of the shared data; the local representation of the shared data including, for each of the parts of the shared data, a respective small-scale representation occupying a small part of the first workstation's respective display;
presenting on the respective display of a second one of the workstations a full-scale representation of a first one of the parts of the shared data, the full-scale representation occupying a substantial part of the second workstation's respective display; and
after receiving from the second workstation's respective user input device a signal requesting an operation affecting the first part of the shared data, including in the first part's respective small-scale representation an indication of the operation affecting the first part.
18. A collaborative system comprising:
a plurality of workstations each having a respective display and a respective user input device;
shared data means for storing shared data, the shared data including a set of parts; and
user interface means connected for accessing the shared data stored by the shared data storing means and for presenting on the respective display of each of the workstations a respective local representation of the shared data; the local representation of the shared data including, for each of the parts of the shared data, a respective small-scale representation occupying a small part of the respective display; the user interface means further being for presenting on the respective display of any of the workstations a full-scale representation of any of the parts of the shared data, the full-scale representation occupying a substantial part of the respective display; the user interface means further being for receiving from the respective user input device of any of the workstations at which the full-scale representation of a first one of the parts of the shared data is presented a signal requesting an operation affecting the first part of the shared data and, after receiving the signal requesting the operation, including in the first part's respective small-scale representation on the respective display of each workstation an indication of the operation affecting the first part.
