Thin Client Comment Overlay for Web Document Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thin client applications do not allow users to interact with comments in documents, specifically unable to add comments and view their positions within the document, limiting collaborative communication in web-based document editing processes.
Innovation Solution
Implementing a thin client application that enables users to view and edit documents via a web browser, with XML files sent from the server containing comments and their positions, allowing HTML overlays to highlight comment locations and providing an HTML comments panel for adding and replying to comments, which are then saved on the server and synchronized with other clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thin client application is used to access documents via web browser, then accessibility and ease of operation are improved, but functionality for interacting with comments is lost
Solution Approach 1:
The patent introduces an HTML overlay as an intermediary layer between the thin client application and the document comments. This overlay contains interactive elements (hotspots, comment indicators) that enable full comment functionality within the web browser interface, resolving the contradiction by mediating between the simplified thin client and the complex commenting requirements
2Loss of information
If comments are displayed in a thin client application, then information availability is improved, but the ability to interact with and locate comments is worsened
Solution Approach 1:
The patent adds a spatial dimension to comment display by implementing an HTML overlay that positions comment indicators and hotspots at their exact locations within the document image. This spatial mapping allows users to visually locate comments in context and interact with them directly, transforming the flat comment list into a spatially-aware interface
3Productivity
If collaborative commenting is enabled via thin client, then productivity is improved, but system complexity increases
Solution Approach 1:
The patent creates a visual copy of the document as an image within the HTML overlay, allowing comments to be anchored and displayed on this copy rather than requiring the original rich client application. This copying approach enables collaborative commenting functionality to run in the simpler web browser environment, improving productivity while managing system complexity
Data Source
AI summary
A document accessible on a network may be opened by multiple users. A user may use a thin client application to access the document, wherein an image of the document and XML data including comments and locations of the comments in the document. Hint icons are displayed in the document where comments are anchored. Upon selection of a hint, an HTML comments pane may be displayed to a side of the document, exposing comments and replies to comments currently stored in the document. The comments pane may be scrolled to the comment associated with the selected hint. Additionally, highlighting may be provided over elements in the document associated with a selected comment. Comments may be added via the comments pane and saved to the document on the network. Comments and comment location data may be communicated to other clients, allowing for collaborative communication via a thin client application.
