Human Computer Interaction Using Hand Gesture

Abstract

In this modern age the advancement in
ubiquitous computing has made the use of natural user
interface very much required. The presence of
computers and making use of the facilities of human
computer interaction in our societies will obviously
bring and mark a positive impact on our societies. Either
it was the day when the technologies had not been so
advanced or todays when the technologies has been
advanced so much that we spent most of our times to
communicate, play, do our jobs with the machines and
many more, even then human beings had used and are
still using a broad range of gestures to communicate or
interact with each other. Human gesture is a mode of
non - verbal interaction medium and can provide the
most intuitive, originative and natural way to interact
with computers. Our main goal is to make the
interaction between human and computer as natural as
the interaction between humans. The objective of this
paper is to recognize the static hand gesture images (i.e.
frames) based on shapes and orientations of hand which
is extracted from input video stream recorded in stable
lighting and simple background conditions. We can use
this vision based recognized gestures to control
multimedia applications (like Windows Media Player,
Windows Picture Manager, VLC Player etc.) running on
computer using different gestural commands.
