Abstract
A method includes receiving a wireless warning signal. The method also includes identifying a type of warning associated with the wireless warning signal. In addition, the method includes generating at least one stimulus based on the identified type of warning and capable of being detected by a user. As particular examples, the at least one stimulus includes visual and/or tactile stimuli that differ based on the identified type of warning. The visual stimuli may be produced by a stimulator on a hardhat worn by the user. The tactile stimuli may be produced by a stimulator in a wristband worn by the user.
