A ubiquitous computing provides advanced dynamic
environments where humans want to make assorted types of
interface for interaction with media and information without
any physical restrictions [1]. Computers now a days are a
fundamental part of any educational core curriculum hence the
educational systems also provide a very large domain ofapplications for ubiquitous computing.
The user interfaces in
vogue are seldom designed with the dexterity performance in
desired educational and teaching assistive system. Evolution
of computer from super computers to desktops to palmtops
has made the presence of human computer interaction felt in
nearly all the aspects of life. The key board, mouse etc lack
the sensitivity desired in required application. Eventually the
researchers putting in their efforts in the field of Human
Computer Interaction made a common emphasis to design and
develop the user interfaces capable enough fulfill the intended
performance criteria desired in the dynamic environment.
Such interfaces can be developed by exploiting the
phenomena of instinctive communication and manipulation
accomplishments of humans facilitating the human computer
interaction even at the further higher degree. A dynamic
environment makes the user free to interact with the
computing devices without any physical contact with it. This
characteristic of HCI makes it particularly very much suitable
for the teaching methodology that is quite dependent on hand
gestures. Also learning for students could be made easier if the
complex commands of the dynamic applications of computers
are controlled through easier hand gestures, for example
browsing Images in an image browsers with help of hand
gestures or controlling the power point presentations with the
usage of hand gestures without need of learning various
commands involved, from a distance without the need of any
physical contact with the devices.
