non-verbal communication using hand movements to convey messages

A hand gesture is a form of non-verbal communication where movements or positions of the hands convey specific messages or emotions. These gestures can be culturally specific, such as a thumbs-up for approval, or universally understood, like waving to say hello or goodbye. In professional contexts, hand gestures can be used to enhance presentations, signal instructions, or facilitate silent communication in noisy environments.
