Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visually impaired individuals face significant challenges in using computers due to the reliance on visual information recognition and input methods, with existing technologies like screen readers struggling to effectively convey complex graphical information and braille terminals limited in functionality.
Innovation Solution
A method and system that utilizes a multi-array tactile cell-based smart braille device with a tactile user interface to convert visual graphic information into tactile graphics, allowing visually impaired users to intuitively interact with web pages by analyzing HTML structures, prioritizing content areas, and generating tactile outputs for browsing services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen reader is used to output visual information through voice, then visually impaired people can access computer information, but the difficulty in recognizing screen output information increases significantly when information quantity increases
Solution Approach 1:
The patent segments the web page content into multiple regions of interest (ROIs) based on HTML structure analysis, prioritizing important elements like headings, navigation, and content sections. This allows the screen reader to focus on and present information in manageable segments rather than overwhelming the user with all content at once, reducing the difficulty of detecting and measuring screen output information.
Solution Approach 2:
The patent performs preliminary action by analyzing the HTML structure of web pages before presenting information to visually impaired users. The system pre-identifies and prioritizes important content elements based on semantic analysis, so that when information is output through voice, it is already organized and prepared in a user-friendly sequence, reducing the cognitive load and detection difficulty.
2Ease of operation
If braille information terminal is used to deliver text information through tactile sense, then visually impaired people can access text content, but the device can only perform limited functions and cannot express graphic information
Solution Approach 1:
The patent makes the braille information terminal universal by integrating it with a smart device (smartphone, tablet, or computer). The terminal can now not only display text information but also access and present graphic information, multimedia content, and interact with various applications through the smart device's capabilities while maintaining tactile output. This multi-functionality resolves the limitation of performing only basic text functions.
Solution Approach 2:
The patent introduces a smart device as an intermediary between the braille terminal and the internet. The smart device processes web page content, analyzes HTML structures, and converts various types of information (text, images, videos) into tactile representations that the braille terminal can output. This intermediary enables the braille terminal to access and express graphic information that it could not handle independently before.
3Productivity
If visual information recognition method is used for computer interaction, then ordinary people can efficiently use computers, but visually impaired people face huge limitations in recognizing output information and performing instant interaction
Solution Approach 1:
The patent replaces the visual recognition mechanism with a tactile feedback mechanism. Instead of relying on users to visually perceive and recognize information displayed on screens, the system uses speakers to output auditory information and tactile display devices to provide tactile feedback. This substitution allows visually impaired users to interact with computers efficiently without visual capabilities, maintaining productivity while eliminating the barrier of visual information recognition.
Solution Approach 2:
The patent implements feedback mechanisms that provide real-time tactile and auditory responses to user actions. When users navigate through content or interact with interface elements, the system provides immediate feedback through the tactile display and speaker outputs. This feedback loop enables visually impaired users to understand the state of the system and adjust their interactions accordingly, improving ease of operation and maintaining efficient computer usage.
