The Driver feedback bar device consists of a bar of LEDs (used to display the driving behavior during a trip); a buzzer; an iButton reader for driver identification; and two buttons: a home button and a work button.
During a trip, the Driver feedback bar displays the current driving behavior, by lighting LEDs from left (green) to right (red).
