AR in the Education Industry

What is Augmented Reality?
Augmented reality abbreviated as AR is an interactive experience of a real-world environment where the objects that reside in the real-world are enhanced by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. The information can be additive (adding more feel to the environment) or destructive (masking off the unnecessary natural environment).

Some common examples of the vast use of AR are mobile games like Pokemon Go and the popular social media photo app, Snapchat. These apps use AR for analyzing real-time user surroundings and further enhance user experience.

AR exhibits certain similarities with VR but has quite a few differences as well. Virtual Reality (VR) is entirely based on the virtual reception of the information, while in Augmented Reality (AR), the user is provided with more computer-generated information that enhances the perception of reality.

Taking a real-life example, VR can be used to create a walk-through simulation of a building under construction while AR can be used to show the building’s structures on a live view.

Uses of AR in Education
The field of AR recently showed some massive development after the immense popularity of apps like Pokemon Go. Recent upgrades have started to find its uses in the vast education industry. The traditional method of education is slowly becoming obsolete, and with the increasing technological growth, the education system is being digitized. The education technology industry giant, namely EdTech, is slowly adopting the use of AR and is predicted to reach around $252 billion by 2020, growing at a 17% annual rate.

Augmented Reality serves several purposes. It helps the students acquire, remember, and process the information. Additionally, AR makes learning easy and fun. Its use is not limited to the pre-school level but can be used equally till college and even at work.

Benefits of Augmented Reality
Due to a large number of benefits of Augmented Reality, its usage has become very frequent in learning. Its main advantages are –

  • Accessibility of Material – Augmented reality has the unique potential to replace the traditional paper textbooks, physical models, or printed manuals. It offers portable and less expensive learning materials. As a result of this, education becomes more accessible and mobile.
  • No special equipment requirements – Apart from a typical smartphone, Augmented Reality doesn’t need any more sophisticated equipment as in the case of VR.
  • Higher Engagement and Interest – Interactive AR based learning has a significant impact on students helping them in understanding and remembering the concepts for a more extended period.
  • Faster and effective Learning Process – Through visualization and immersion in the subject, AR ensures that the concept is deeply instilled in mind. A picture is worth a thousand words, Isn’t it? So instead of thousands of words of theory, the user can visualize the matter with their own eyes.
  • Practical Learning – The use of AR in professional learning gives an accurate reproduction of in-field conditions that can help in mastering the practical skills required for a specific job.
  • Improved Collaboration Capabilities – AR offers vast opportunities to diversify and shake up boing classes. Interactive lessons involving the whole level at the same time help in building qualities of team-work.
  • Safe and Efficient Workplace – Consider the field of heart surgery or a Space Shuttle. Without the introduction of actual dangerous equipment, the students can be taught in real life, how to solve problems.
  • Universality – Augmented Reality applies to any form of education and can significantly enhance the learning experience.

Challenges faced by Augmented Reality

There are certain challenges that you should take into account while using Augmented Reality:

  • Necessary Training Required – Conventional Teachers can find it difficult using new technologies into practice. Only the innovative and open-minded teachers will be ready to apply Augmented Reality in education.
  • Hardware Dependency – Requirement of AR equipment is necessary to make full use of this technology. All the students might not have a smartphone capable of supporting AR applications.
  • Platform-Based Issues – The AR app built must run equally well on the various available platforms.

 

Examples and Use Cases

The most popular application of Augmented Reality is unarguably in the field of education.

  1. It can help a teacher explain using a visual representation of the subject, which would help the students understand a subject better.
  2. Another case of Augmented Reality is distance learning. Students can learn even outside the classroom anytime, anywhere.

 

On a final note, Augmented Reality is a blessing in the education industry. It is not only beneficial to the students but also makes the work of teachers more comfortable and convenient.

Virtual Reality Explained – A deep insight

Virtual Reality (VR) is coined from the combination of two words – ‘virtual’ and ‘reality’. Virtual as from definition means near, and Reality is what we experience in our daily life. You probably won’t do things like diving deep in the oceans, standing beside a volcano, or going on a voyage to Antarctica, but with Virtual Reality, you might be able to do it all without even leaving your cozy sofa. All of this sounds tempting and proves that the future of virtual reality and artificial intelligence is bright and their scope is immense. Virtual reality is created in the real world using high-performance computers and some sensory equipment, like a headset and gloves. The idea of VR originated in the minds of the great Thomas Edison, who pioneered it with the name “Kinetograph.”

Here are a few examples of Virtual reality (VR) usage-

  • Virtual reality in education (e.g., military training, or pilots)
  • Virtual reality in games. VR systems use either the Virtual reality headsets for a portable VR experience or multi-projected environments for generating realistic images, sounds and other sensations that ensure a user’s physical presence in a virtual environment.

 

A person using VR can look around 360 degrees and can move around. This virtual effect is mainly created by the VR headsets that consist of a head-mounted display, with a small screen in the front of the eyes. Virtual Reality usually packages auditory as well as video feedback. Following are very crisp descriptions of everything you need to know about virtual reality.

Experiencing Virtual Reality can be categorized into various types:

  • Fully Immersive – Three things help in fulfilling a complete VR experience, a computer model, a powerful computer that can adjust to the actions made by the user, and some surround-sound loudspeakers.
  • Non–Immersive – An alternative way is using a widescreen and using headphones. It doesn’t fully immerse a user, though it is a kind of Virtual reality.
  • Collaborative – The virtual experience is the same as in the fully immersive state, but it offers the idea of sharing the virtual world with other people.
  • Web-based – This is a web-based virtual reality analogous to HTML namely VRML (Virtual reality markup language)
  • Augmented Reality – Mobile devices nowadays are as capable as computers used to be. It spawned the idea of Augmented Reality (AR). There are close links between virtual reality and augmented reality. (Augmented Reality also has numerous applications in the education industry).

With the introduction of power-packed features in personal computers and smartphones, Virtual Reality devices saw significant development and grew rapidly. On a large scale, Virtual Reality is used in the entertainment industry, particularly in the gaming industry for the enhanced gaming experience.

Which devices are used for VR on a Commercial Scale?

Datagloves

Giving people the ability to touch objects and feel things in the virtual world is one of the most significant achievements of the VR industry. One technical method of implementing this is using fiber-optic cables that records the data about how much a finger is stretched. Other technologies include strain gauges, electromechanical devices, or the piezoelectrical sensors to measure the finger movements.

Head-Mounted Display(HMDs)

It is the most critical component for a VR experience. The difference between a computer and a VR is the presence of a 3D screen on a VR screen which moves according to the user movements. The HMD looks like a giant motorbike helmet, which consists of two screens, a blackout blindfold that blocks outwards light and stereo headphones (not necessarily). They usually have built-in accelerometers that keep a check on the user’s movement and the direction.

Wands

Even more straightforward than a dataglove, a wand is like a stick that can be used to touch, to point to, or to otherwise interact with a virtual world. It has the position sensors or the motion sensors (such as accelerometers) built-in, along with some mouse-like buttons or scroll wheels. The advantage that the wands take over the conventional VR equipment is that they are wireless.

Concluding, Virtual Reality is instrumental in the gaming industry and the commercial use of Virtual Reality for the education industry for pilots and military training is a very creative use of VR. It is also extensively used for enhanced entertainment purposes for short VR shows for a deep insight into Virtual Reality.

Now the question arises – how much does virtual reality cost? A long time ago, the VR equipment was very costly for its personal use. However, the recent VR equipment by Google, namely Google Cards is a cheap and efficient solution for experiencing Virtual Reality in your own home. Virtual reality seems to be the future of extensive development.
