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 of applications 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.
