Terminologies Used in Virtual Reality.
Virt ual R e ality (VR ) and Virt ual E nv ironme nt s (VE) are used in digital
communities interchangeably. These terms are same as Synthetic
Experience, V irtual Worl ds, Artificia l Worl ds or Artificial Real ity.
There may be sl ight v ariations but they al l essentially mean an
interactiv e and immersiv e (w ith the feel ing of presence)
experience in a simul ated (autonomous) w orld.
T e lepre senc e is the tel eoperation systems for remote manipul ation of
physical objects. It is a specific kind of v irtual reality that simulates
a real but remote (in terms of distance or scal e) env ironment.
C y be rspac e is consensual hallucination w ith graphical representation
of data abstracted from the banks of ev ery computer on the w eb.
T e lex istence enables a human being to hav e a real -time sensation
of being at a pl ace other than w here he or she actually exists, and
being abl e to interact w ith the remote env ironment, w hich may be
real , v irtual, or a combination of both.
HC I (Human- C omput e r Int e rac t ion) refers to the study and process by
w hich humans interact w ith computers. V ery basic HCI is something
as simpl e as a keyboard and mouse w hil e adv anced HCI coul d be
thought-controlled interactions be tween a person and a computer.
Hapt ic s refers to the capabil ity to sense a natural or synthetic
mechanical env ironment through touch. Haptics al so incl udes
kinaesthesia , the abil ity to perceiv e one’s body position, mov ement
and w eight.
Hapt ic s t e c hnologies prov ide force feedback to users about the
physical properties and mov ements of v irtual objects represented
by a computer. Haptics incorporates both touch (tactil e) and
motion (kinaesthetic) el ements.
