What is it about?

ClarIAr is a feature created to upgrade the functionality of TalkBack, improving the experience for visually impaired users in Android smartphones. It implements Artificial Intelligence to describe images on the screen with more accuracy and details. In other words, ClarIAr is an accessibility resource created to enable blind people to use their phones in a more efficient way!
