Hand signals
Non-verbal communication using hand gestures
Hand signals are a form of non-verbal communication that involve the use of hand gestures to convey messages. These signals are used in various contexts, including traffic control, sports, military, and emergency services. Hand signals can be an effective way to communicate when verbal communication is not possible or practical.
