Abstract:
In recent years, augmented reality technology is being widely used in various areas.
Augmented Reality (AR) is basically a real view modified by a computer. It uses computer
generated imagery and sounds to enhance one’s current perception of reality. While virtual
reality describes an imaginary world that exists in computers and our minds, augmented
reality is a mixture of real world and virtual world. It is therefore different for the human
mind to tell the difference between real world and augmented reality. In this paper, we
describe the development of a prototype that uses augmented reality to control electrical
devices like fan, motors, AC etc. by hand gestures. Up to 8 electrical devices can be
controlled. A virtual plane is present between user and display. The user interacts with this
virtual plane and hands and fingers are tracked and gestures recognized. These gestures are
then used to select the button on the display which are used for selecting a particular device
and to turn it on or off as per the requirement of user. This project is very helpful for people
of physical limitations like old age people, physically disabled people and also used for
industrial and office work.
