From gazing to winking, there is so much that can be expressed with the appropriate eye contact. Eye contact is a primary component of any interpersonal communications and the study of such eye behaviour is called oculesics.
LOOKING UP
When a person is thinking, they would usually look upwards. It symbolises a person visualising his or her thoughts and hence allows you to communicate concepts better with that person. Humans tend to look upwards and to the left as a natural reflex because we use our right brain to analyse and think logically. But, when a person looks upwards and to the right, this indicates imaginative construction within the mind. Such glances are always associated with betrayal and the telling of lies.
LOOKING DOWN
In most cultures, it is rude to sustain long eye contact with another person. We look down when talking with others so as to show respect. This scenario can be observe when a superior is talking to the subordinates. The subordinates look down to indicate submission. They are trying to give the signal to their boss that they pose no threat and also messaging " Please do not hurt me!". Besides, looking down also can be interpreted as a person feeling guilty. Moreover, looking down and to the left indicates a person talking to themselves. But when looking down and to the right, the person experiencing internal emotional turmoil.
The sideways look can be interpreted in so many ways. It is an action to avoid or show boredom towards a topic or conversation, with the most common interpretation being that the person is seeking some distraction. Lateral eye movement can also be interpreted as someone telling lies and projecting shiftiness and the eye movement gives the impression they are looking for an escape route in case their lies are found out. Lateral eye movements also happen when the person is being conspiratorial and they want to ensure no one else is listening in.
LOOKING AWAY
Eye contact or lack thereof can clearly be used to give the signal of boredom in interpersonal communication.
Looking away is actually a signal to tell other parties that you are ready to end the conversation, bored of the topics and probably feeling annoyed as the other person talking too much. However, looking away can also be interpreted differently and one example is when women tend to look away as a signal of submission (especially when communicating with someone whom they find attractive).
GLANCING
Glancing or flash look can be used to show a desire for a thing. For example, when you feel hungry you will indirectly glance at food. If you feel ready to leave the place, you would glance at the door to indicate the desire to leave. When you glancing at a person can indicate the interest to communicate with and talk to the person. On of the most usual glancing represent the desire to look at something forbidden. Example, if you notice a sexy lady with a very short miniskirt, men would definitely glance at her as often as they can. like this girl.....??? :)
