The advances in the computational and semiconductor
technology made the intelligent devices affordable to extent
by which many a applications have been developed. It
involves multimedia technologies empowered virtual and
augmented reality as there key component. These applications
involve different users varying from children, to elderly,
disabled, and peoples with heterogeneous proficiency,
aptitude, dexterity, and reflex skills lacking the training and
capabilities to use numerolittral keys and selection processes.
The user may benefit from such means of interaction in
communicating with computing devices used in dynamic
environment. Most of the users abhor the complexities of the
present interaction devices and methods because of the time
and attempts needed for understanding the functionalities and
the chances of failures arising out of the cognitive burden.
Besides some interaction steps involving the swiftness in
reflex such as double-click, and drop & drag dissuades users
particularly elderly or affected by some physical or cognitive
disorder [2]. Hence Human computer Interaction (HCI) is
persistently in pursuance of being inexpensive, easier in use,
versatile and fast so that it may direct to the virtual
environment to make a world where the interaction feels real.
