CART Captioning serves ADA compliance. It also serves as a communication tool to provide accessibility for the deaf and hard-of-hearing, for people with cognitive disabilities and for those who are trying to learn a second language.
CART Captioning is even beneficial to hearing people in settings where normal hearing may be impaired.
CART can be customized for font size, color and background color and displayed on a laptop for one consumer, on a larger monitor for a handful of consumer viewers or on a projector screen for a mass audience.
CART Captioning can generate a transcript or time-coded file, providing a simple record for reference and later use.
A study also found that 80% of people who use captions in general do not have difficulty hearing, which suggests that it could be beneficial for a large subset of users.
