Abstract:
At present, there are no adequate solutions which
facilitate the interaction of computers to handicapped people.
This research addresses that issue and it provides a
comprehensive solution for the problem. The product provides
an alternative to the conventional mouse using computer vision
and voice recognition technologies as key techniques. The user
can use his or her nose's relative movements to move the mouse
pointer and use other mouse actions by voice commands.
Enhanced template matching image processing technologies have
used to track the nose position. Background light changes are
rectified with using adoptive thresholds. The voice interaction is
achieved by using Speech API calls and overall mouse events are
passed to system using system API calls. The only additional
hardware components used are, a web cam and a microphone
which come by default in most laptop computers in built. And
such external microphones and web cameras are available in
very affordable price.
