Ever since humans began to live on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier(障碍),communication is carried out through sign language in which motions stand for letters, words, and ideas. Tourists and the people unable to hear or speak have had to turn to this form of expression. Many of these symbols (标志，符号) of whole words are very clear and exact and can be used internationally; spelling, however, cannot.
Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A wink(眨眼) can be a way of indicating that the part is only joking. A nod means approval(赞同) , while shaking the head indicates a negative(否定的) reaction.
Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warn, and instruct people. While language is the most common form of communication, other systems and techniques also express human thoughts and feelings.
