Gesture-based communication refers to the use of physical movements, such as hand signs or body language, to convey messages or emotions. This form of communication can be found in various cultures and is often used alongside spoken language to enhance understanding. It plays a crucial role in expressing feelings, intentions, and social cues. Many communities, including those using American Sign Language (ASL), rely on gestures as their primary means of communication. Additionally, gestures can vary significantly across different cultures, making it essential to understand their meanings in specific contexts to avoid misunderstandings.
