Different Types of Augmented Reality

Augmented reality does not end with your smartphone. There are many more ways to enhance your perception of the world. However, it is important to understand that AR is not a monolithic technology. As is often the case, subtle (and sometimes not so subtle) differences in implementation can play a key role in how successful a technology is for a specific use case. Several categories of augmented reality technology exist, each with varying differences in their objectives and applicational use cases.

1.Marker Based Augmented Reality

Marker-based (also called Image Recognition) uses a camera and some type of visual marker, such as a QR/2D code, to produce a result only when the marker is sensed by a reader. Marker based applications use a camera on the device to distinguish a marker from any other real world object. Distinct, but simple patterns (such as a QR code) are used as the markers, because they can be easily recognized and do not require a lot of processing power to read. The position and orientation is also calculated, in which some type of content and/or information is then overlaid the marker.

2.Markerless Augmented Reality

As one of the most widely implemented applications of augmented reality, markerless (also called location-based, position-based, or GPS)AR, uses a GPS, digital compass, velocity meter, or accelerometer which is embedded in the device to provide data based on your location. A strong force behind markerless technology is the wide availability of smartphones and location detection features they provide. It is most commonly used for mapping directions, finding nearby businesses, and other location-centric mobile applications.

3.Projection Based Augmented Reality

Projection based AR  works by projecting artificial light onto real world surfaces. Projection based  applications allow for human interaction by sending light onto a real world surface and then sensing the human interaction (i.e. touch) of that projected light. Detecting the user’s interaction is done by differentiating between an expected (or known) projection and the altered projection (caused by the user's interaction). Another interesting application of projection based augmented reality utilizes laser plasma technology to project a three-dimensional (3D) interactive hologram into mid-air.

4.Superimposition Based Augmented Reality

Superimposition based AR either partially or fully replaces the original view of an object with a newly augmented view of that same object. In superimposition based AR, object recognition plays a vital role because the application cannot replace the original view with an augmented one if it cannot determine what the object is. A strong consumer-facing example of superimposition based augmented reality could be found in the Ikea augmented reality furniture catalogue. By downloading an app and scanning selected pages in their printed or digital catalogue, users can place virtual ikea furniture in their own home with the help of augmented reality.
