Connectivity has become a must for many industries, including the automotive one. But if until now the connection is more between the car and other electronic devices used by the driver, little has been done to make drivers of different cars communicate with each other. However, the first rudimentary systems begin to arrive, such as the all in all intuitively simple one of 3A Productions, the Ukrainian start-up that created ‘Emodis‘. It is a display, connected to a smartphone application suitable for the purpose, facing the following cars.
Emodis can send, on an LED display installed on the rear window of a car, of the pre-set or personalized messages which can be read by the driver of the following car. Among those visible on Kickstarter, the site where the founders are trying to raise additional funds for the project, there are messages (in English, for now) like ‘thank you’, ‘baby on board’, ‘attention’, plus other directions or service signs, such as ‘Taxi’.
The system is easy to install: the display must be connected to the electric socket inside the car, thanks to a 2-meter cable, and the user must download a special application on a smartphone, which manages the messaging through Bluetooth technology. You can change colors, display special effects and combine messages. Indeed the application allows you to save four ‘standard’ messages, possibly the most used by the driver, and to send them on the display through the use of a small remote control with four buttons. The messages can be displayed sequentially.
Obviously, like all devices of this type, the effectiveness of communication it does not depend so much on the type of display, colors and configuration of the app, but on the choices of the driver or passengers. When used to insult another driver, or to show useless messages, it can be a not-so-wise stunt and can potentially be distracting. It might instead be more useful in case of emergencies or as a function of law enforcement operations.
In any case, the issue of communication aimed at the cars in front still remains unresolved. In fact, it is not yet possible for those driving behind a car to warn it of a technical problem or a potential danger, for example. Except the not always effective use of high beams.
