What feature should be added to multimedia for people who might have trouble seeing content?

The inclusion of alt text is essential for making multimedia content accessible to individuals who may have difficulty seeing. Alt text, or alternative text, is used to describe images and visuals within the content. This descriptive text is read aloud by screen readers, which assist visually impaired users in understanding what the images depict. By providing context and information about the visual elements, alt text ensures that users who rely on assistive technologies can experience the content in a meaningful way, equal to that of sighted individuals.

While interactive elements, sound descriptions, and high-contrast colors can enhance the user experience and accessibility for different needs, they do not specifically address the needs of those who have visual impairments as effectively as alt text does. Alt text directly aids users in comprehending images, making it a fundamental requirement for ensuring accessibility in multimedia.
