  This paper describes an intelligent system ABHIVYAKTI, which would be
pervasive in nature and based on the Computer Vision. It would be very easy in
use and deployment. Elder and sick people who are not able to talk or walk,
they are dependent on other human beings and need continuous monitoring, while
our system provides flexibility to the sick or elder person to announce his or
her need to their caretaker by just showing a particular gesture with the
developed system, if the caretaker is not nearby. This system will use
fingertip detection techniques for acquiring gesture and Artificial Neural
Networks (ANNs) will be used for gesture recognition.
