Custom Summary View for Screen Reader Data Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blind and visually impaired users face difficulties in navigating and analyzing large datasets in applications like Microsoft Excel, as existing screen readers do not provide efficient means to summarize and quickly access important data, leading to increased time and effort in data manipulation and analysis.
Innovation Solution
The development of a custom summary view feature in screen reader software that allows users to create and manage summaries of important data, including monthly totals and grand totals, by assigning labels to cells or regions, enabling quick navigation and updating of data summaries without re-specifying data, and automatically detecting title rows and columns, even without the screen reader installed at file creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen readers read all data in a spreadsheet sequentially, then complete data accessibility is achieved, but navigation time and user effort increase significantly
Solution Approach 1:
The patent segments the spreadsheet data into meaningful groups or categories (e.g., by column, by data type, by importance). Instead of reading all data sequentially, the screen reader allows users to navigate through segmented data structures, presenting information in organized chunks that reduce navigation time while maintaining complete accessibility to all data elements.
Solution Approach 2:
The patent extracts and highlights key information or summary data from the spreadsheet, presenting it first to give users an overview. Users can then drill down into specific sections as needed, rather than navigating through every single data point in sequential order. This extraction of essential information reduces initial navigation time while preserving full data accessibility.
2Productivity
If screen readers provide detailed data analysis features, then data utility is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service features where the screen reader automatically performs common data analysis tasks such as identifying data patterns, summarizing information, or navigating to relevant sections based on user context. This automation provides enhanced data utility without requiring complex manual configuration or processing, thereby improving productivity while controlling system complexity.
3Speed
If custom summary views are implemented, then data retrieval speed is improved, but initial setup time increases
Solution Approach 1:
The patent allows users to create custom summary views that pre-process and organize data according to specific criteria before actual data retrieval occurs. These pre-configured views store the organization logic and data groupings, enabling rapid data retrieval subsequent to the initial setup. The preliminary action of creating these views trades off initial setup time for significantly improved ongoing data retrieval speed.
Data Source
AI summary
A screen reader software product feature referred to as a custom summary view, or custom summary, has been developed. The custom summary feature solves the major problem faced by blind users when working with large sets of data. That problem occurs as a result of an inefficiency of gleaning important data from within these larger sets. The custom summary provides the ability to gather such data into a summary that can be navigated easily. This ease of navigation greatly levels the playing field in the competitive workplace for blind workers and students alike. Also taught is a feature, referred to as a multiple region support, which allows users to define blocks of contiguous cells containing data as “regions” when a document such as a spreadsheet is displayed by a screen reader. Regions can either be named by the user or be defined simply by the top left and bottom right cell addresses that represent the boundaries of the block of contiguous cells containing data.
