An information display unit for an automobile includes a display screen
and a user interface presented on the display screen that simultaneously
presents at least two display elements each depicting information
relating to a different subsystem of the automobile (e.g., a navigational
subsystem and an audio subsystem). The user interface visually emphasizes
one of display element relative to another other display element in
response to a predetermined stimulus such as a user's hand actuating or
coming near a radio control knob or an approaching turn recommended by a
navigation system.
