Imagine a world with a technology that creates the 3 dimensional images of a virtual object around you with which you can interact, see, hear, smell, and even touch it. Technologies such as computer graphics, virtual reality, and augmented reality together can be used to implement this in real world. Augmented reality actually superimposes virtual objects into the real environment with the real objects for enriching the viewer’s experience Augmented reality with virtual reality in virtual space, also enhances the audience perception by displaying additional information. In this survey we present the different technologies that are involved in the implementation of augmented reality. These technologies are displays which are used for displaying or combining the virtual object by the real environment, tracking or gesture recognition helps in real time interaction part while the modelling is used to register the objects into 3D for enhancing the quality and perception of the viewer.
