In the United States, a nationwide Commercial Mobile Alert Service (CMAS) is being planned to alert cellular mobile device subscribers to emergencies occurring near the location of the mobile device. The plan specifies a unique audio attention signal as well as a unique vibration attention signal (for mobile devices set to vibrate) to identify that the incoming message pertains to an emergency. Ratings of vibration signals of varying lengths and patterns were obtained from 44 deaf users of mobile devices for the perceived effectiveness of the signal in getting their attention in an emergency situation. Longer signals received higher ratings than shorter ones, and three signals with temporal on–off patterns were rated significantly better than a constant vibration. The U.S. government's recommended vibration signal for the CMAS, an important feature for access to emergency alerts by deaf persons, is supported by the results of the study.
