Accessibility Lock for Collaborative Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with visual impairments or learning disabilities accessing collaborative documents via real-time collaborative editing platforms may not be notified of simultaneous changes, leading to a mistaken view of the document's content due to the lack of awareness of edits made by others while using screen readers.
Innovation Solution
Implementing an accessibility module that provides a time-based lock or pause on collaborative documents, allowing users to lock the document for exclusive editing or pause edits, alerting others when a screen reader user is accessing the document, and queuing changes for review when the user is ready.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time collaborative editing is enabled, then multiple users can edit simultaneously and productivity is improved, but users with screen readers cannot be notified of simultaneous changes and reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting when a screen reader user is accessing a document and proactively applying an accessibility lock or pause before simultaneous edits can occur. This preventive measure ensures that changes are queued and applied only when the screen reader user is ready, maintaining document view accuracy while preserving collaborative editing capabilities.
2Adaptability or versatility
If screen reader access is provided, then accessibility is improved, but simultaneous changes are not notified and information completeness deteriorates
Solution Approach 1:
The system introduces an intermediary accessibility lock mechanism that mediates between screen reader users and other collaborators. When a screen reader user is detected, the lock prevents simultaneous changes from being applied immediately, instead queuing them for later application. This intermediary layer ensures that all changes are communicated to the screen reader user, preventing information loss while maintaining accessibility.
3Ease of operation
If document editing is unrestricted, then ease of operation is improved, but concurrent edits create confusion and device complexity increases
Solution Approach 1:
The system dynamically adjusts document editing restrictions based on the detected accessibility needs of users. When a screen reader user is identified, the system automatically applies an accessibility lock or pause, temporarily restricting simultaneous edits. When no accessibility needs are detected, normal unrestricted collaborative editing resumes. This dynamic approach maintains ease of operation for able-bodied users while providing necessary protections for screen reader users, without requiring permanent complex coordination systems.

AI summary
A computer-implemented method in a document editing module is provided. The document editing module comprises a processor configured by programming instructions encoded in non-transient computer readable media. The method comprises providing, by the processor, contents of a document to a user interface; providing via the user interface, by the processor, an object that when selected indicates a desire to lock the document from editing by another document editing module or another instance of the document editing module for a fixed time period; and modifying, by the processor, one or more attributes of the document that indicate that the document is locked for editing and a fixed length of time the document is locked for editing when the object has been selected.
