Browser Switching Video to Text for Screen Reader Voicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen readers struggle to voice video content on web pages, such as Flash movies, QuickTime movies, and Java applets, making it difficult for visually impaired users to understand the content displayed on personal computers.
Innovation Solution
A data processing device and computer-readable storage medium that acquires and displays alternate web pages with greater potential for voicing, allowing the screen reader to voice text-based content instead of video, by determining the user's visually impaired status and controlling the acquisition and display of web data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the browser displays video content on web pages, then the visual experience for sighted users is improved, but the screen reader cannot voice this data making it inaccessible for visually impaired users
Solution Approach 1:
The patent introduces an intermediary mechanism (the browser's detection and switching system) that mediates between video content and text-based alternatives. When the browser detects screen reader usage, it automatically switches from displaying video to displaying text-based web data, ensuring accessibility without requiring direct integration between screen readers and video formats.
Solution Approach 2:
The system dynamically adjusts the display format based on detected user needs. The browser continuously monitors for screen reader usage and automatically transitions between video and text-based content delivery, making the system adaptable to different user requirements in real-time.
2Loss of information
If the browser acquires web data with video display commands, then the completeness of web content is improved, but the screen reader fails to voice the data reducing accessibility
Solution Approach 1:
The browser performs preliminary detection of screen reader usage before fully processing and displaying web content. By detecting the presence of a screen reader in advance, the browser can proactively switch to text-based web data formats that are reliable for screen reader voicing, preventing accessibility issues before they occur.
Solution Approach 2:
The system changes the format parameter of web data from video-based to text-based when screen reader usage is detected. This parameter change ensures that the content remains complete and accurate while becoming reliable for screen reader voicing.
3Adaptability or versatility
If the browser displays text-based web data, then the screen reader can voice the content improving accessibility, but the video content experience for sighted users is lost
Solution Approach 1:
The browser dynamically switches between text-based and video-based content display based on real-time detection of screen reader usage. When a screen reader is detected, the system transitions to text-based content for accessibility; when no screen reader is detected, it displays video content for optimal visual experience.
Data Source
AI summary
A data processing device is connected to a web data providing unit that provides web data via a network. The web data has at least one of first web data and second web data corresponding to the first web data. A screen reader can be installed on the data processing device. The displaying unit displays the web data. The screen reader voices the first web data displayed on the displaying unit and fails to voice the second web data displayed on the displaying unit. The acquiring unit acquires the web data from the web data providing unit. The determining unit determines, based on visually impaired information indicating that the user is a visually impaired, whether or not the acquiring unit should acquire the first web data from the web data providing unit even if the user instructs the acquiring unit to acquire the second web data from the web data providing unit.
