One of our biggest design concerns for First EMT is creating an interface that is universally accessible regardless of language, culture, or education. To make language selection universally accessible we are using a combination of a flag icon, text, and audio stating the language a button selects.
One part of the program will have phrases that a health care provider may want to say to a patient. We originally were going to record audio of each phrase. After speaking with Dr. James Sutton we actually learned that some cultures can be pretty "freaked out" by random talking boxes. As a solution we plan on recording video of translators speaking. This will also allow us to incorporate American Sign Language.
