Augmented Reality

What is augmented reality?

It is defined as the technology and methods that allow overlaying of real-world objects and environments with 3D virtual objects using an AR device, and allow the virtual to interact with the real-world objects to create intended meanings (Softwaretestinghelp, 2022).

There are four types of AR:

1. Marker-Based
2. Marker-Less
3. Project-Based
4. Superimposition-Based

Marker-Based:

A marker, which is a special visual object like a special sign or anything, and a camera are used to initiate the 3D digital animations. The system will calculate the orientation and position of the market to position the content effectively (Softwaretestinghelp, 2022).

Marker-Less:

It is used in events, business, and navigation apps, for instance, the technology uses location-based information to determine what content the user gets or finds in a certain area. It may use GPS, compasses, gyroscopes, and accelerometers as can be used on mobile phones (Softwaretestinghelp, 2022).

Project-Based:

This kind uses synthetic light projected on the physical surfaces to detect the interaction of the user with the surfaces. It is used on holograms like in Star Wars and other sci-fi movies (Softwaretestinghelp, 2022).

Superimposition-Based:

In this case, the original item is replaced with an augmentation, fully or partially. The below example is allowing users to place a virtual furniture item over a room image with a scale on the IKEA Catalog app (Softwaretestinghelp, 2022).

Educational-Uses of AR:

AR can be used in many ways within education. For example, it can be used in anatomy and students can perform virtual dissections and they can view animations and movement of body parts and muscles.

AR can be used for science with the focus of the stairs. Students can use an AR application that allows them to see constellations and how they work in real time.

5 Apps for AR:

1. Human Anatomy Atlas 2021: This app allows students to do virtual dissections and view how muscles move
2. Starwalk: This app allows students to observe and see different constellations in real time
3. Plantale: This app allows students to study a plants life journey and anatomy.
4. Boulevard AR: This app brings artwork from the National Portrait Gallery to life to bring a lifelike museum experience
5. Touch Surgery: This app allows for doctors and surgeons to prepare for surgeries and procedures

ISTE Standards:

1. 2.6.b I am presenting a way for students to see how they can learn through AR via different apps available to them.
2. 2.5.b I am designing authentic learning opportunities for my students by talking about AR as a possibility to engage in deep learning.
