ACKNOWLEDGEMENT
I thank my seminar guide Ms Shekha Chenthara , Lecturer, CUSAT, for her
proper guidance, and valuable suggestions. I am indebted to Mr. David Peter, the
HOD, Computer Science division & other faculty members for giving me an
opportunity to learn and do this seminars. If not for the above mentioned people my
seminars would never have been completed successfully. I once again extend my
sincere thanks to all of them.

ABSTRACT
Multi-touch technology is an advanced human-computer interaction
technique that recogonises multiple touch points and also includes the
hardware devices that implement it, which allow users to compute
without conventional input devices . Multi-touch consists of a touch
screen (screen, table, wall, etc.) or touchpad, as well as a software that
recognizes multiple simultaneous touch points, as opposed to the
standard touchscreen which recognizes only one touch point at a time.
Multi touch using Frustrated Total Internal Reflection is a simple,
inexpensive, and scalable technique for enabling high-resolution multi-
touch sensing on rear-projected interactive surfaces. Different
applications for multi-touch interfaces both exist and are being proposed.
Some uses are individualistic eg iPhone, iPod touch, MacBook Pro,
MacBook Air. The use of multi-touch technology is expected to rapidly
become common place.Page 5
