Augmented Reality has a great potential, it is not possible to deny the applications of AR. In every field, AR has enormous potential where rapid and vital information is required. It has been applied experimentally to school, business, and training. AR systems have been used in medicine, manufacturing, robotics, entertainment, tourism, and recently in social networking and education.
Augmented Reality in Medical
Doctors use AR for visualization of the human body and to train medical staff for a surgery. This is very useful for training, medical students using AR for practice in a controlled environment. AR provides hidden information to the surgeon such as the heartbeat, the blood pressure, etc.. Doctors also use AR to look inside a patient by combining X-ray with video. Live overlays of ultrasound, CT, and MR scans is another application of AR in medicine.
Augmented Reality in Tourism
AR is also currently used in the tourism sector, the aim of this technology in tourism is to improve the tourist experience. It provides personalized content and services to the tourist and citizens. By providing real-time information AR increasing the expertise of tourist. The tourist guide based application is developed with an
aim to locate, guide and give information related to a place. Augmented Reality in Manufacturing Manufacturing is another category of AR applications. Assembly, maintenance, and repairing of complex machinery is easier with AR, 3D information is overlaid upon the actual equipment which showing step-by-step process of the assembly.
The instruction is automatically adjusted to the actual conditions. AR in manufacturing reduces the training required for assembly operators . In the field of manufacturing, it is a good technology for training.
Augmented Reality in Entertainment
AR is also applied to entertainment to create AR games. Several games have been developed using AR, such as the alien-battling, dolphin-juggling, AR-Hockey. In live sports broadcasting, AR increases the visibility of important and interesting scenes. Tangible Cubes is an application of AR games the aim of this application is learning about animals characteristics, habit, and reasons for possible loss . Sightseeing Guidance is another application, it enhances the real environment with virtual objects and provides virtual tour guides to help tour.
Augmented Reality in Education
In traditional teaching methods, everything is under the control of teacher and the educational systems not offer required ways to enhance students creativity, for this purpose AR is one of the most recent technology to be used. AR application in education is very wide. In every field of education, it can be used. Researchers progressively recognized AR for teaching-learning. The application of AR receiving attention day by day first it was used in the 1990s for training pilots. Per the Horizon Report 2011 in next two-three years, AR will provide new opportunities for teaching and learning. AR has the advantage of virtual information overlaying on real-world which offering a meaningful way to the users to increase learning experiences. AR games have the potential to change the classroom into a new and exciting situation where the students are engaged in real scenarios and gaining knowledge through activity and learning through action. AR system supplementing real-world objects with computer generated objects. It is not restricted only to the visual information it can also be applied to hearing, touch, and smell. It can be applied to a much wider range area and education is an area in which AR technology is more valuable, for example
using AR technology interface children can be seated in a classroom and see each other at the same time and a virtual heart is there between children and trying to learn about heart. This result is much better than other methods because that is more like a natural environment. Researchers divided it into five groups Discovery-based learning, Object Modeling, Skills Training, AR Gaming, and AR Books. Discoverybased learning is usually used in museums, in astronomical education, and at historical places. Object modeling AR applications allow users to know physical properties or interaction between objects. Skills training is used to train individuals such as airplane maintenance and repair. AR games provide educators with highly interactive and visual forms of learning. AR books offer students a new way of learning to engage and motivate learners. Nowadays different new technologies are used to enhance the
classrooms, such as multi-touch and computer gaming. AR is also one of the new technology and research shows that AR is the best technology for classrooms and it is the classroom of the future. On different methods AR is used in education, for example, AR in mathematics and geometry education, AR in geography, AR in chemistry, AR
in books, etc. In AR, the learners see and listen to additional computer-generated information and this is the main advantage of AR as compared to traditional teaching methods.
AR is an interactive educational technology for teaching chemistry. AR shows students that how an atom or molecule consists. It is most applicable when the phenomenon cannot be explained or to show visually to students. It is also very helpful to perform different experiments which are dangerous or expensive in the real world. Ion and electron are usually invisible but using AR it becomes visible. Experiments and repeating experiments are important but due to non-availability of chemicals and instruments, this is not possible. AR can reduce cost, risk and provides a realistic environment for experiments. Augmented Biology Biology is the study of life and organisms. Human structure and anatomy are the main approaches to biology. Students have difficulty with visualization and to know the relationship of one organ with another. AR has great potential to provide 3D visualization of the human body and meaningful information of organs in a realistic environment. Augmented Mathematics and Geometry Several AR applications were developed for mathematics and geometry. Using these applications teachers and students can construct geometric shapes together in virtual space and share information with each other. The main advantage of
using AR in mathematics and geometry is that visualization and construction of 3D objects instead of using traditional methods (pen and paper). Using AR users can naturally explore properties of different geometric shapes such as curves and surfaces. Several researchers recommended that AR can be used to enhance and fortify
students motivation and learning. Nowadays with the use of mobiles and computers, AR is much more powerful than ever before and very helpful to deliver AR experiences.
Researchers are trying to use AR in classroom-based learning in different subjects and
to adopt it into augmented books and student guides. Research on AR in education
shown that using AR increases students motivation for learning. The benefits of AR in
learning is better understanding and engagement.
