Technology

Summary

Images and graphics can make content more pleasant and easier to understand, especially for people with cognitive and learning disabilities. People with low vision and other visual impairments also use images to orient themselves in the content. However, images can create major barriers when they are not accessible.Images must have text alternatives that describe the information or function represented by them. This ensures that images can be used by people with various disabilities.

How it solves user need

  • Assistive technology can read text aloud, present it visually, or convert it to braille.
  • Text alternatives may help some people who have difficulty understanding the meaning of images such as photographs, drawings, graphic designs, paintings, graphs, charts, and animations.
  • People who are deaf, are hard of hearing, or who are having trouble understanding audio information for any reason can read the displayed text.
  • In the future, text alternatives will be rendered as sign language or a simpler form of the text language.
  • People who are deaf-blind can read the text in braille.
  • Text alternatives can help people more easily find and repurpose non-text content.
