Blindly Beautiful: Crafting Image Descriptions for Complex Graphics
A Picture Says a Thousand Words, But What if You Can’t See?
As web developers and sysops, we strive to create inclusive online experiences. One crucial aspect of accessibility is providing alternative text (alt text) for images. However, when it comes to complex graphics, simply describing the visual elements can be insufficient. In this article, we’ll explore how to craft effective image descriptions that convey the essence of intricate graphics.
The Problem with Simple Descriptions
Imagine a graphic illustrating the different stages of a process, such as a software development workflow. A simple description like “image of a developer coding” might not accurately convey the complexity and context of the graphic. This can lead to users who rely on screen readers or have visual impairments missing out on important information.
Creating Effective Image Descriptions
So, how do we create image descriptions that effectively convey complex graphics? Here are some best practices:
1. Focus on Functionality
Instead of describing what’s in the graphic, focus on its purpose and functionality. For example: “image showing the different stages of a software development workflow, highlighting key milestones and responsibilities.”
2. Use Clear and Concise Language
Avoid using jargon or technical terms that might confuse users. Use simple language to describe complex concepts. For instance: “image depicting the various components of a web application, including user interface and backend systems.”
3. Emphasize Key Takeaways
Highlight important information or key takeaways from the graphic. This can be especially useful for complex data visualizations or infographics. For example: “image illustrating the correlation between website engagement metrics and marketing campaigns, highlighting areas for improvement.”
Code Example: Using ARIA Attributes
When adding alt text to images, don’t forget to include ARIA attributes (Accessible Rich Internet Applications) to provide additional context for screen readers and other assistive technologies. Here’s an example using HTML5:
<img src="complex-graphic.jpg" alt="Software development workflow"
aria-label="Stages of software development process: planning, design, coding, testing, deployment, maintenance."
role="img">
In this example, we’ve added ARIA attributes to provide a more detailed description of the graphic for users who rely on screen readers.
Conclusion
Crafting effective image descriptions for complex graphics requires attention to detail and a focus on functionality. By following best practices and using clear, concise language, you can ensure that your images are accessible to all users. Remember to include ARIA attributes when adding alt text to provide additional context for assistive technologies. With these tips in mind, you’ll be well on your way to creating inclusive online experiences that “blindly” beautiful graphics will never hold back.
