This paper presents a method to control pointer with
the help of camera for a person who is not able to control the pointer with
hands. Physical problems result from brain paralysis
are the most dominant obstacles for pointer control. This paper aims to control
pointer with the help of human-computer interaction technologies instead of
hands. The proposed design is similar to common pointer control. According to
disability condition, people can choose the usage of the system because of the
adjustability of the system. One can control the pointer by wearing a colored
wristband or any item on body parts like arms, feet or any other moving part of
the body. The designed system requires software, a camera, and a table lamp.
The working principle of the system is inferring information from camera and
transforming this information to pixels to control the pointer on the screen.
In this paper, computer vision system was combined with Java class to control
the pointer. When the camera gets the first snapshot from a real-time video,
first, the software finds the location of the colored item on the screen then
moves the pointer towards to location. In this real-time system, clicking is a
problem because of the physical inabilities. In order to solve this problem, we
use another colored item on the field vision of the camera. According to the
location of the second object, the software decides about left or right clicks.
