Braille Chording Accessory for Game Controller Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Game controllers are challenging for visually-impaired or blind users due to their complex operation and inability to provide accessible input and output methods, as existing solutions inadequately translate game text and audio into braille, limiting accessibility in gaming experiences.
Innovation Solution
A braille chording accessory for game controllers that includes a braille display and paddles, allowing users to input and output braille characters, translating game text and audio into tactile braille for reading and inputting, with a design that fits standard hand sizes and customizable for user preference, using electronic circuits and sensors to detect touch forces and translate signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard game controller controls are used, then device complexity is reduced and ease of manufacture is improved, but accessibility for visually-impaired users deteriorates
Solution Approach 1:
The controller is divided into distinct functional zones: standard controls for able-bodied users and braille-specific controls for visually-impaired users. The braille display module and braille input paddles are separate attachable components that segment the controller into modular units, allowing each user type to access their specialized controls without interference.
Solution Approach 2:
Braille translators serve as intermediary devices that convert visual game text and audio information into tactile braille representations. These translators mediate between the game system and visually-impaired users, translating inaccessible visual information into accessible tactile form through the braille display module.
2Adaptability or versatility
If braille display and input controls are added, then accessibility for visually-impaired users is improved, but device complexity increases
Solution Approach 1:
The controller design incorporates universal functionality by integrating both standard controls and braille-specific controls into a single device. The braille display module and braille paddles can be attached to enable braille functionality, while the standard controls remain available for all users, making the controller universally accessible to different user types.
Solution Approach 2:
The controller configuration is dynamic and adaptable rather than fixed. Braille components can be attached or removed based on user needs, allowing the controller to dynamically adjust its functionality. The system can switch between standard mode and braille mode depending on which components are present and which user type is operating it.
3Loss of information
If existing braille translation solutions are used, then accessibility is partially improved, but information completeness deteriorates due to inadequate translation of game text and audio
Solution Approach 1:
Braille translators act as intermediary devices that bridge the gap between visual game content and tactile braille output. They translate game text and audio information into braille characters displayed on the braille display module, preserving information completeness by converting all visual information into accessible tactile form rather than losing any game content.
Solution Approach 2:
The system replaces visual information delivery mechanisms with tactile braille mechanisms. Instead of relying on visual displays and audio alone, the system substitutes these with a braille display module that provides tactile feedback, and braille paddles that provide tactile input capability, thereby substituting mechanical tactile systems for visual and auditory systems.
