With the smart phones are becoming more and more advanced and universal, people also have some problems emerged with the over use of mobile phone or mobile phone addiction, but the most serious problems are the face to face communication between people."Workplace conflicts are common in most organizations. The lack of interpersonal communication only worsens the situation. It's important to remember that 55 per cent of meaning in an interaction comes from facial and body language and 38 per cent comes from vocal inflection. Only seven per cent of an interaction's meaning is derived from the words themselves." (Sunder Ramachandran) Therefore trying to resolve a conflict over phone call is often a bad idea. And "you are always under examination by people around you, awarding or denying you very high prizes when you least think of it." (Ralph Waldo Emerson) It means people should leave the comfort of cubicle and build an interaction relationship by face to face communication. However, in addition to people will lack a face to face communication between people and affect the eyes health while they play with their smart phones too much.
