I. INTRODUCTION

Augmented reality (AR) is a view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sound, video, graphics or 3d Models, in other words, it is an overlay of computer graphics on real life objects. This paper provides a thorough introduction to this fairly new

This visualization could aid in training for surgery, through ultrasound images, Computed Tomography scans or MRI scans that provide an useful view of the patient in real time. With this system, the information is captured by sensors and displayed on the patient, thus showing exactly where to perform the operation.These virtual drawings show in an easy and graphical way the tasks that need to be done and how to do them efficiently. With ultrasound imaging, for example, the doctor can view a three-dimensional virtual image of the fetus overlaid on the abdomen of the pregnant woman. Moreover, AR could guide doctors to find the site of a tumour during needle biopsies. Future applications of Augmented Reality in the medical field will be craniofacial surgery visualization and guide in reconstructive surgery.

5.2 Advertisements

Special techniques have been developed to insert advertisements into certain areas of a specific place during the broadcast. We often see 3D advertising in football games promoting products or services. These images are perfectly integrated using reference points in the stadium. Using this system, production costs are reduced by creating virtual sets than can be stored in a database.

The next development of AR will be initially on the aircraft manufacturing. On the other hand, its introduction to the medical field, will take longer than in other areas. AR will probably be used in medical training before than surgery. Another area where AR will develop strongly in the coming years will be in tours through outdoor environments by wearing a Head-mounted display, facilitating the development of advanced navigation systems and visualizations of past and future environments. After solving the basic problems of Augmented Reality, advanced virtual elements will be developed that will be perceived as realistic as the real world. To achieve this purpose, the conditions of lighting, texturing, shading and registration will be almost perfect, so we will wear a pair of glasses outdoors that will show us realistic virtual elements with which we will interact normally.

ACKNOWLEDGMENT

I would like to express my greatest gratitude to my teacher Asst. Prof. Kavindra Singh for his continuous support for the paper, from initial advice & contacts in the early stages of conceptual inception & through ongoing advice & encouragement to this day.
