The word “Reality” means a real world environment. Augmented Reality is the one which takes the present real world environment and projects digital (i.e. computer generated) inputs to it, including images, sounds, graphics, text, and video. It is one of the latest technologies offering a new way to educate users. As the use of mobile devices is rising globally, so is the use of AR on mobile devices.
How does Augmented Reality work?
Through augmented reality, the user can view the real world with computer generated images overlaid on various objects within the real world. The device could be a smartphone, a wearable device, or a laptop with an optical device. The device should be loaded with the software to recognize an image and help display its respective augmented model in the device.
Augmented reality (AR) enhances real life scenarios with artificial images, whereas virtual reality just swaps the real with the artificial.
Some new aspects unique to mobile AR that support learning encourage the use of:
- User’s mobility
- Geographical position of the user
- Physical place where learning can occur
- Formal learning to connect with informal learning
What are the components of AR?
- Head mounted display
- Tracking system (GPS)
- Mobile computing power
How do we classify Augmented Reality?
AR is classified according to:
- Device or technology used
- Mode of interaction
- Method of sensory feedback
- Personal or shared experience
- Character of the experience
- Learning activities or outcomes
A suggested AR taxonomy in mobile learning to categorize different aspects:
What are the levels of AR?
AR has four levels:
- Level 0: Physical World Hyper Linking: This is the oldest form of AR and the most developed. It is also the simplest and does not involve any real time rendering of graphics. The best example is QR codes (2D image recognition) that we see in every product.
- Level 1: Marker based AR: In this level, markers trigger the text, sound, or visuals. The marker is the hard copy of a black and white square image, which you place it in front of an web cam to view a 3D animation.
- Level 2: Markerless AR: It is the most powerful of all. It’s so simple that you take out your mobile device and experience the AR, which depends on a combination of GPS and compass.
- Level 3: Augmented Vision: It is a form of lightweight transparent wearable display.
What does the future hold for AR?
AR is being developed in line with mobile technologies. Some areas where AR can be used for better training include healthcare, the military, and sales and marketing training. In healthcare, we can adopt AR to better explain, for example, the anatomy of the human body, or the parts of the heart, for better understanding. In the military, AR can be used to train soldiers on the enemy location points, etc. In sales and marketing, AR can be used for training the workforce on how to promote their new product or servicing a product.

Finally, using AR for training will promote engagement and motivation among the learner’s or users. It provides an immersive learning experience to provide a unique way of making sense of the real world around us.
