Web: All content is described via semantic markup, ARIA landmarks, roles, and labels. NOTES: 1) the aXe plugin states that forms that are initially hidden (e.g. our 'Send Feedback' form) have hidden labels. When the form becomes active, all of its content - including labels - is visible. 2) The jQuery-ui library we use attaches roles to elements that the aXe plugin complains are non-standard, such as adding the 'button' role to <button> tags. We can alter the library to prevent this if it is an issue for screen readers.

VisualDx supports multiple log-in methods, including IP-based authentication, and embedding credentials in the url. All application state is stored in the web application's querystring, so even if the session expires no work will be lost.

302.1 Without Vision

Supports

VisualDx is a web application that uses semantic HTML and WAI-ARIA attributes to provide text equivalents for all visual elements.

302.2 With Limited Vision

Supports

As a web application, VisualDx supports standard browser-based accessibility features for size and contrast. VisualDx is a responsive web application, and all elements are styled based on font-size. Changing font size in the browser causes the application to resize all content responsively.

302.3 Without Perception of Color

Supports

Color is only used to present information in measures of differential strength - and in those cases is always paired with a text description; e.g. a green bar followed by 'Excellent'.

302.4 Without Hearing

n/a

VisualDx does not contain audio content or features.

302.5 With Limited Hearing

n/a

VisualDx does not contain audio content or features.

302.6 Without Speech

n/a

VisualDx does not require speech for input, control, or operation.

302.7 With Limited Manipulation

Supports

VisualDx does not require fine motor control or simultaneous manual operations.

302.8 With Limited Reach and Strength

n/a

VisualDx supports any keyboard or pointing devices that are compatible with a web browser. Users' reach or strength should not affect their ability to use VisualDx.

302.9 With Limited Language, Cognitive, and Learning Abilities

Supports

VisualDx is designed to be simple, consistent, clear, multi-modal, error-tolerant, and attention-focusing.

• Navigation is consistent throughout a site
• Similar interface elements and similar interactions produce predictably similar results

• VisualDx supports increased text sizes
• Images are readable and comprehensible when enlarged
• Color alone is not used to convey content
• VisualDx remains readable and functional when images or styles are disabled.

• VisualDx uses Photographs with captions, illustrations, diagrams, icons, and animations to convey complex information and enhance content
• VisualDx pairs icons or graphics with text to provide contextual cues and help with content comprehension

• VisualDx uses stylistic differences to highlight important content, but does so conservatively
• Content is organized into well-defined groups or chunks, using headings, lists, and other visual mechanisms
• White space is used for separation and to focus attention

• Reading level of medical content is consistent and adequate for the audience
• All medical content begins with an introductory summary and table of contents
• Content is succinct, condensed to 'handbook' length instead of 'medical textbook' length.
• Line height and Line length are set to ensure text readability
• VisualDx uses content appropriate Sans-serif fonts (which are found to be more readable) with adequate text size
• All text elements have a color contrast ratio of at least 4.5:1
• No horizontal scrolling

• No interaction has a time-out of less than an hour
• All inputs are labeled clearly
• VisualDx gives users clear and accessible form error messages and provide mechanisms for resolving form errors and resubmitting the form
• Breadcrumbs are consistently used in the navigation header to give the user context for each page
• All functions can be easily canceled or reversed
• VisualDx provides adequately-sized click-targets and ensures that functional elements appear clickable
• VisualDx uses underline styling for links only
• There are multiple methods for finding content. e.g.: search, sitemap, building a differential diagnosis, and links from other diagnosis texts can all be used to navigate to a diagnosis details page
