They've learned how to communicate in many ways: from facial expressions to gestures and sounds to various signals.

We express our emotions using universal facial expressions.

Types of Communication

Communication in the wilderness is possible if you have a flashlight, colored warning flares, or use body language. Correct signaling makes it easier for the group to communicate. But it also saves lives.

Over 180 years ago, a special communication code was developed – the Morse code consisting of dots and dashes.



The Morse Code

The Morse code communication relies on standardized sequences of dots and dashes transmitted as sound signals, electric impulses, or light flashes. To start broadcasting a message, all you need is a flashlight and knowledge of basic codes, such as S.O.S.
