This paper presents a novel approach to the understanding of Haptic
\nand its related fields where haptics is used extensively like in display
\nsystems, communication, different types of haptic devices, and
\ninterconnection of haptic displays where virtual environment should
\nfeel like equivalent physical systems. There have been escalating
\nresearch interests on areas relating to haptic modality in recent years,
\ntowards multiple fields. However, there seems to be limited studies in
\ndetermining the various subfields and interfacing and related
\ninformation on haptic user interfaces and its influence on the fields
\nmentioned. This paper aims to bring forth the theory behind the essence
\nof Haptics and its Subfields like haptic interfaces and its applications.
