There are five aspects to the hat’s user interface.
Buttons are pressed by the user in order to communicate, both with the Safety Control Center
(SCC) and with other users.
LEDs indicate to the user when there is an event or pending communication.
The speakers play standard and custom messages to be heard by the user. They also enable
two-way communication with the SCC and/or other users.
