Exploration on the Use of AR in Teaching Fields

 

Introduction:

Augmented reality(AR) is the integration of digital information with the user's environment in real time. Unlike virtual reality(VR), which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it.

In the past few years, AR has combined with our lives at a very fast pace, and our education is no exception. Below, we will discuss the use and topic of AR in education through several thematic units.

Learning Objectives:

1.Introduce "augmented reality"(AR) to let learneres know this important issue in technology.

2.Show some examples of AR's applications(especially in education) in life to let learners be aware of its wide influence.

3.Introduce an AR software application tool(MAKAR) to provoke learners to think about the advantages and disadvantages of AR(MAKAR) in teaching.

The Definition of Augmented Reality (AR)

What is Augmented Reality ?

Augmented reality (AR) is a type of interactive and reality-based display environment, or simply said as the new level of integration of digital information that has the capabilities of computer generated display, sound, text and effects to enhance the user's real-world experience. Augmented reality combines real and computer-based scenes and images to deliver a unified but enhanced view of the world. Unlike virtual reality (VR), which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it.

Augmented reality has many different implementation models and applications, but its primary objective is to provide a rich audiovisual experience. AR works by employing computerized simulation and techniques such as image and speech recognition, animation, head-mounted and hand-held devices and powered display environments to add a virtual display on top of real images and surroundings.

The basic goal of an AR system is to enhance the user’s perception of and interaction with the real world through supplementing the real world with 3D virtual objects that appear to coexist in the same space as the real world. AR systems have the following properties:

1) Blend real and virtual, in a real environment

2) Real-time interactive

3) Registered in 3D

Here, registration refers to the accurate alignment of the virtual and real objects. Without accurate registration, the illusion that the virtual objects exist in the real environment is severely compromised.

With the Layar Creator, a self-service web application for activating print pages with digital content, Layar is pioneering the interactive print movement and paving the way for a more robust future for the publishing industry in a digital age.

Pro and Cons of AR

The Advantage of AR

  • Blurs the line between what is real and what is computer-generated.
  • Information about the surrounding in real world becomes interactive and digitally manipulable.
  • Reality with more information added that is normally not available in real world.

The Disadvantage of AR

  • People are missing out on what is right in front of them in real world.
  • Lack of privacy.
  • Quite expensive to develop and maintain.

2. AR applications in life

Applications in Game

Gaming is one of the hottest industry when it comes to augmented reality and virtual reality. There are plenty of augmented reality examples in the gaming space. In a typical AR gaming experience, the developer superimposes a pre created game environment over real world objects.

EX:Pokémon GO

The game Pokémon Go uses camera, gyroscope, clock, and GPS to provide a breakthrough gaming experience to the user. The game brings in Pokémon on the user's’ screen which is blended in the real environment using camera and GPS technology. The game made thousands of users leave the comforts of their desks and go out to hunt Pokémons.

Applications in Retail

In retail, augmented reality can be used to improve the buyer’s experience by bridging the gap between the perception of the product and the actual product. By using augmented reality, buyers can know the size and look of the product in a much realistic way. This solves one of the biggest problem faced by online retailers today.

EX:IKEA PLACE

Built using Apple’s new Augmented Reality ARKit, the app includes 3D and true to scale models of everything from sofas and arm chairs, to foot stools and coffee tables. Giving you an accurate impression of the furniture’s size, design and functionality in your home.

Applications in Military

Augmented reality is used by the military to simulate real war experiences and situations in order to provide better training to the soldiers. Augmented reality is not only beneficial for field troops but also for the air force. Data like altitude, enemy location and airspeed can be provided seamlessly to the pilots through the heads-up display. Though it sounds like a small advantage, it can save precious seconds in emergencies and war situations.

Heads-Up Display (HUD):

The term "heads-up" name applies because the pilot doesn't have to look down at the aircraft's instrumentation to get the data he needs.

Head-Mounted Display (HMD):

The term is used by ground troops. Critical data such as enemy location can be presented to the soldier within their line of sight. This technology is also used for simulations for training purposes.

Applications in Advertising or Marketing

From creating a better buying experience for the customers to increasing the level of engagement, augmented reality is proving to be very helpful for the marketers. Many advertising campaigns are planned using augmented reality technologies to stand-out from the competition.

EX:Starbucks in 2012

By using a dedicated Starbucks AR app to scan their cups users could watch the design come to life.

Applications in Medicine

Medical students use AR technology to practice surgery in a controlled environment. Visualizations aid in explaining complex medical conditions to patients. Augmented reality can reduce the risk of an operation by giving the surgeon improved sensory perception.

3. What can AR be applied in teaching?

Augmented Reality in Education Introduction

In this video we will introduce you with AR in Education, so please watch it until the end. 

Usage of Augmented Reality in Education

The perspective of engaging smartphones and usage of augmented reality for education process is amazing, but meantime only few educators really move this way. AR may help in various ways to give students and pupils extra digital information about any subject, while making complex information is easier to understand.


Explain abstract and difficult concepts

AR technology has an ability to render in 3D model anything that may be hardly visualized in a classroom, at a computer, in minds of students. Inverse abstract and difficult content in visual models help students get deeper understanding about lesson topic.

That works especially good with visual learners and also helps others get alternative ways of integration theoretical material into real concept.

Involving and interacting

Including AR into lessons may help educators directly involve students in the studying process by interacting 3D model. Taking part in such kind of things helps motivate students, capture their attention for the whole augmented reality classes and helps them understand subject deeper.

Interaction with AR may be part of lesson like a teaser, support of main topic providing extra info to students or be the main content of a lesson.

Canadian tech company CASE transformed a wall of school gym into huge skee-ball game by adding augmented reality layer to it. Therefore, children should launch rubber balls onto wall to destroy the model of floating shapes visualized on it by the projector.

Discover and Learn

Visitors of museums by using their mobiles may access AR and discover historical events by exploring various additional content in connection to objects. AR provides visitors with extra information about what they see or even allows to virtually equip some stuff to themselves or take tour to the past.

On the other side museums mostly can not show whole collection to visitors due to space limitation, lack of resources or just high value of objects. Using AR capabilities provides great opportunities for museums to present more than it is possible in normal conditions.

Augmented reality give visitors ability to use their mobile devices as pocket-tool through which area around them receive endless additional layers of information.

Objects modeling

Manual elements in education, such as the usage of their hands in practice or solving some quiz, may help learners better understand a lesson. By using apps medical students may easily learn human anatomy. Usage augmented reality in education enable them exploring different parts of body individually and discover its unique features.

AR allows students to interact with 3D model. Whatever, rotating, customizing it by setting transparency, changing colors, styles and even parts.

Interactive books

AR books provide deeper understanding of complex content. It also help make process of learning brighter and engaging.

Sadly but, reading common books didn’t motivate children to study science. If so, using books that includes digital AR content can make a deal. For example, revising pages through devices that support AR features may give access to additional content. As a result, springing to life 3D models with animations, sound and interaction actions attracts children attention.

Skills training

In many cases theoretical knowledge is hardly enough to become a good specialist in the wide range of professions.

In measure to give students skills they need in practice education system should change. So, today concepts of teaching should move to way more active position. Finally, as more practical learning method would be included in learning process as less students would stay as passive observers.

Technical students need practice and hands-on experience to get skills of maintenance and assembly suitable for their profession. Sadly, but often skills can’t be practiced in a classroom.

In addition, using AR features may help them by virtual study and practice with fully digital content, or additional 3D models linked to real parts. AR tutorial animations and graphics content also may give extra knowledge about new methods and innovative concepts.

Meantime, AR technology could create different situations and simulations suitable for the practical process where students may acquire some experience.

How does it feel to have AR in Classroom?

Students' Feedback

Let us figure out what they said!

The Limitations of AR in Classroom

The Limitation of AR in Classroom

Issue :

Many participants in an AR learning exercise agree that the AR tools are good but most participants do not consider the tools to be as effective as reading textbooks. They find that using AR tools to obtain information is not easy. The reason might be that although the AR tool itself is easy to operate, the procedure of sending the image, recognizing the text and then getting the meaning of the text is time-consuming. This is because the technology used the 3G network to connect to the Internet. Accordingly, the participants may need to wait a short time for the information to be sent back from the server.


Solution:

Increased Internet access will give students the opportunity to use AR via a smartphone. This has the potential to make AR a powerful learning tool that can help students to gain content knowledge and maintain that knowledge through their interactions with the smartphone activities. 

The Future of AR in Education

The Future of AR in Education

The advantages and beneficial uses of AR features are able to help improve their visualization skills and engage students in learning processes. These features can also help teachers to explain well and make the students understand better what they are taught in class. 

The use of AR technology has also received mixed feedback from participants and students who have shown their interest in using AR in their learning processes. The good responses are important because they indicate the willingness of students to actively engage in their studies through AR tools. 

As we know, AR technology is still very new in education and there are still some limitations. However, the review of the research indicates that most of the limitations are related to technical issues (read-network issue). Such limitations can be overcome over time as research on the integration of AR in education is replicated and improved. 

When the potential of AR technologies is more fully explored, the beneficial functions of AR can begin to be used widely in all fields of education and the efficiency of the teaching and learning process will be improved.

6. Conclusion

Conclusion

Nowadays, the development of technology has a lot to do with teaching methods. Virtual reality(VR) and augmented reality(AR) are two very popular issues concerning education. Besides education, they are also being applied in various areas like games, military, medicine and so on. Although these great technologies brings us lots of possibilities and conveniences, they still have some disadvantages that are worth thinking. What we need to do is keep track of the development of AR (VR also) and pay attention to both its strengths and weaknesses. In the end, never stop thinking the issue on your own!
