"...human communication relies also on vision to the degree that bodily signals and responses are perceived by the eye." (Havelock. p.98)

Our senses are another way that one is able to respond to communication. The eye, in particular, replaced the ear by reading what was written. Writing replaced oral communication. This innovation changed the human society. Storing communication was made easier as the written word was seen by the eye as opposed to hearing speech by the ear. Take for example a conversation between an interviewer and the interviewee. The interviewee listens while making proper eye contact, and sitting in an upright position. The persons body language, speech, resume(written), and their sense of hearing needs to be up to the standards of the interviewer or company that they are attempting to seek employment from. The interviewer watches the potential employee as they ask them questions, to see how they are responding by body movement and language.
The eye has replaced the ear in many ways as far as the written word is concerned. But the two rely on one another. The ear hears while the eye sees. Oral and written are communication tools that rely on the senses.
