Detail of Perspective ?

Tell me about the detail of  perspective ?

Perspective is actually a specific view of any thing. We see only that details/information which is relevant to us due to any reason. For example as discussed in lecture a person may have role of student and teacher at a time, by considering it from student perspective we only collect those details which are related to student role. Similarly when we consider it as a teacher we only view that details which are a related to his/her teaching role and will ignore the details of his/her student role.
