Abstract

A method and new user interface are provided for tracking content change of an on-line document in a real-time collabrative editing environment. Given a collaborative document model composed by content fragment with change attributes such as user information, operation type and operation location, the method considers the impact of time continuity of operation in the perception of changes to present editing changes to users. The new method and accordingly new user interface provides the capablility to filter and consolidate editing changes in real-time via the timeline control.

Analysis and Timeline visualization for content change track in a collaborative editing application

Many methods and systems are for detecting and listing changes and/or differences between an original document and a modified version of the document. This kind of method has no concept of timeline an just archive every change into revisions and list the changes all at a time in the user interface. Our method focus on tracking the change history by given time period and given collaborative editor.

Some existing methods consolidate a combination of keystrokes into one change by its location, author and type of action for readability.

However keystrokes that are made in different times are usually consolidated into one change which is not intuitive to users. For example, Bob created a document which contains "Hello Beautiful World" as the content. Bob typed "Hello" three days ago and "Beautiful World" yesterday

Most products will present "Hello Beautiful World" as one change because they didn't take the time as one of the factor when consolidating the changes.

In a real-time collaborative editing environment, users want to track the real-time changes, not only provided by different people but also made in different time periods. Accordingly, there is a need for a new approach along with an improved user interface for content track change in real-time collaborative editing.

We propose the following method and accordingly novel visual facades for content track change:

Given a collaborative document model composed by content fragment with change attributes( user information, operation type, operation location), capability to present editing changes to users in consideration of the impac...
