        MIS deals with computer-based system that provides managers with the tools to
organize, evaluate and efficiently manage departments within an organization.
MIS phase one was dealing with programming languages and in this second phase, applications of
soft-wares in real life is yet to be learnt. One such application is HCI(Human-Computer Interaction)and
BCI(Brain-Computer Interfaces).

          Human-Computer Interaction is
the study of how humans interact with machines especially computers. Many
people are realizing the importance of HCI, and are learning a lot to
understand its concepts. Different
users form different models about its interactions and have variety of ways in
learning and keeping knowledge and skills (different models for
“left-brained” and “right-brained” people). Cultural
and  sometimes national differences play
a part. Another consideration in studying or designing HCI is that user
interface technology changes fast, hence it leads the way to the new
interaction possibilities to which previous research findings may not apply.
Finally, user preferences also change as they gradually master new interfaces1.

        BCI is the collaboration with a brain
and a devices which enables signals from brain to guide/direct some external
activities. The interface enables a direct communications pathway between the
brain and the object to be controlled. Examples like in the case of cursor
control, the signal is transmitted directly from the brain to the mechanism which
directs the cursor, rather than taking the normal route through the body’s
neuromuscular system from the brain to the finger on a mouse2.

of BCI include military mind-control, where The US Defense Advanced Research
Projects Agency (DARPA), did a test run in US army and found successful. Other
applications deals with the use of sensors to detect the electrical signals of
the user’s brain(tele presence), and controlling mobile robot agents is one
area where BCI appears to hold much promise(to overcome injuries), and in some
applications like silence talking3.

        Sebastien Grange et al.,(2003) did a computer vision software library which seems to be
the key component of vision-based applications. There already exists several
libraries, but most of them are large and complex or limited to a particular
hardware/platform combination. This lead to the development of TLIB, an
easy-to-learn, easy-to-use software library with the help of HCI that provides
a complete set of real-time computer vision functions, including image
acquisition, 2D/3D image processing, and visualization 4.
