Virtual reality departs from conventional Human-Computer
Interaction (HCI) and naturally requires a different set of user
input tools. This paper will examine the various types of input
devices that have been developed for use with virtual reality.
When you move your hand, the glove picks up the movement and
sends an electrical signal to the computer which then translates
the movement from real space into virtual space. Often, you are
able to see your virtual hand in the virtual world. This greatly
aids in the hand-eye coordination, necessary for any kind of
positioning in a three dimensional world. Besides being used to
perform tasks that we use our hands in the real world for,
researchers soon realized that this same glove could be used for
architectural walk-throughs, scientific visualization, or any
number of other applications. [AUKS92] This is done by assigning
meaning to hand gestures. The second tool measures the absolute
position (X, Y, and Z axis) andthe orientation (roll, pitch, and
yaw) of the han
