Best Practice 1.10 – Provide captions for videos (Baseline level*)
Provide captions for all videos so that they are accessible by persons with hearing impairment. Captions not only present the content of a conversation but also the important cues and surrounding noises.
* To attain the Baseline level, mobile applications are required to adopt any of the best practices in 1.9, 1.10 and 1.11.
Before Rectification For a video without caption, it is not perceivable by persons with hearing impairment. |
After Rectification Captions as shown in the example above should be provided so that persons with hearing impairment can fully understand the content of the video. |
