A voice-operated, interactive message display system designed for inter-vehicle and extra-vehicle communications. The system includes one or more display units having a matrix of light-emitting elements to transmit a message to other vehicles either to the front, rear, side, or combination thereof. The display units are controlled by a central control unit having a voice recognition and voice synthesis system, which is used to interactively determine a message to display and on which displays to present it. Upon manual activation, the message system vocally prompts the user for the message to display and the parameters for its display. The system may be implemented in at least two different embodiments. In one embodiment a powerful vocabulary memory unit is used and the content of the message is run-time programmable. If a less expensive vocabulary unit is used, the user may choose from a series of preprogrammed messages. Once specified, the message can then be delivered to the displays (front, rear, or side) in normal or mirror imaged formats. The display system can also monitor ambient light conditions to make appropriate brightness and contrast adjustments to maximize message readability. |
