Alt text helps make visual content accessible to all students, including those using screen readers. Generative AI can support this by helping create and improve image descriptions.
For this activity you will use ChatGPT-4o to create alternative text for an image and assess its quality.
- Log into ChatGPT-4o.
- Upload an image and use the following prompt: “Act as an expert in web accessibility and write concise and meaningful alternative text for this image so that it can be described via a screen reader.”
- Use the Writing Alt Text from the BCcampus Accessibility Handbook for Teaching and Learning and review the AI-generated alt text for accuracy, clarity, and relevance.
- Share your assessment, including any refinements or improvements you made.
