[Accessibility](https://help.gideononline.com/accessibility) June 1, 2026 # GIDEON accessibility features ## Comprehensive list accessibility features available on the platform. The GIDEON web application is built to conform with Web Content Accessibility Guidelines (WCAG) 2.1 and 2.2 Level A/AA/AAA standards, the Revised Section 508 standards, and EN 301 549 requirements. The platform is designed to provide a seamless, barrier-free experience for health sciences professionals and students. ### Visual & Display Customization To minimize visual fatigue, assist individuals with low vision, and accommodate light sensitivity, GIDEON provides robust display configurations: - **Native Light and Dark Modes:** Users can freely toggle between light and dark viewing modes across the entire application to adjust foreground and background colors. - **Enhanced Text Contrast:** Text and images of text maintain a high contrast ratio against backgrounds, conforming to AAA-level contrast requirements. - **Fluid Layout Reflow:** The platform is built using responsive web design principles. Content reflows seamlessly when zoomed up to 400% on a standard browser viewport without requiring horizontal scrolling or losing functionality. - **Text Resizing:** Text can be easily magnified up to 200% using standard browser zoom layouts or keyboard commands without losing content or functionality. - **Readability Layouts:** Text across the platform is consistently left-aligned rather than justified, utilizing line, paragraph, and letter spacing optimized for maximum readability. ### Inclusive Map Layouts & Color Perception Data insights within GIDEON’s Visualize module and embedded components do not rely on color alone: - **Accessible Map Schemes:** While standard interactive maps utilize a "traffic light" data scheme, alternative high-contrast color palettes are available specifically to support colorblind users. - **Textual Substitutions:** Where graphic markers are heavily utilized to create interactive outbreak maps, all underlying information is simultaneously available in a textual list format. - **Dedicated Legends:** All colors used in map visualizations are explicitly defined and explained in local, easy-to-read text legend panels. ### Keyboard Navigation & Interaction Control The entire GIDEON platform is fully functional without a mouse, using standard system keyboard commands: - **Standard Navigation Sequences:** Progression through all elements sequentially and logically is achieved using standard `Tab` and `Shift + Tab` controls. - **Activation & Controls:** Interactive components, such as buttons, links, and checkboxes, are engaged using `Enter` or the `Spacebar`. Pop-ups and tooltips can be closed immediately using the `Esc` key. - **High-Contrast Focus Indicators:** A distinct, high-contrast rectangular outline clearly tracks the currently active component when navigating via keyboard. Focused elements always remain fully visible and are never obscured by other layers. - **Interactive Canvas Workarounds:** In complex visual tools, such as the Lab module's Decision Tree, complex pointer actions like drag-and-drop can be fully replicated using standard `Tab` and `Enter` key combinations. - **Bypass Blocks:** Hyperlinks are embedded across pages, enabling keyboard users to skip directly over repetitive blocks of content straight to the main text. ### Interoperability with Assistive Technologies GIDEON uses clean, semantic programmatic structures to ensure complete compatibility with assistive technologies like screen readers: - **Programmatic Structural Markup:** All pages are logically structured using clean HTML headings, labels, and roles to clearly map out relationships for text-to-speech tools. - **Descriptive ARIA Labels:** Non-text components, buttons without visible textual descriptors, and ambiguous system icons utilize explicit `aria-describedby` or `aria-label` tags to communicate their actual purpose. - **Search Auto-Suggestions:** Dynamic search suggestions and lookup entries are programmatically indexed, instantly communicating changes to screen readers. - **Predictable Focus Stability:** Elements never unexpectedly shift context simply by receiving focus. Error messages and system status strings appear as plain text, notifying individuals without forcefully interrupting the active workflow. - **Abuse Protection Adjustments:** Automated security verification is implemented via Google reCAPTCHA v3. This runs invisibly under normal parameters without challenging visual puzzles and contains built-in accessibility adjustments for the response fields. ### Technical Support and Alternate Documentation In compliance with Section 508 and EN 301 549 expectations: - **Accessible Digital Support:** All official technical help, product documentation, and support ticketing paths are housed online in digital formats that adhere fully to WCAG Level AA standards. - **Alternate File Formats:** Upon request, support materials and platform documentation can be supplied in alternative accessible formats, such as large print layouts or accessible PDFs. - **Trained Support Specialists:** GIDEON’s customer service staff are directly trained to address compatibility questions, troubleshoot user setup obstacles, and communicate through telecommunications relay services. - [Access](https://help.gideononline.com/access) - [Accessibility](https://help.gideononline.com/accessibility) - [FAQ](https://help.gideononline.com/faq#main-content) - [Clinical](https://help.gideononline.com/faq#clinical) - [Data questions](https://help.gideononline.com/faq#data-questions) - [Epidemiology](https://help.gideononline.com/faq#epidemiology) - [Microbiology](https://help.gideononline.com/faq#microbiology) - [General](https://help.gideononline.com/general) - [Getting started](https://help.gideononline.com/getting-started#main-content) - [Video tutorials](https://help.gideononline.com/getting-started#video-tutorials) [![GIDEON logo](https://help.gideononline.com/hs-fs/hubfs/PNG-GIDEON%20trademarked%20logo%20vector%20SMALL_BLACK%20BLUE-2.png?width=274&height=59&name=PNG-GIDEON%20trademarked%20logo%20vector%20SMALL_BLACK%20BLUE-2.png "GIDEON logo")](https://help.gideononline.com/) [mailto:info@gideononline.com](mailto:info@gideononline.com) Copyright © 2026 GIDEON Informatics Inc
