Augmented Reality (AR) is a technology that combines the physical world with digital elements in real-time. Unlike Virtual Reality (VR) which takes users to a fully virtual world, AR enriches the real world with layers of information, visuals, and digital interactions. In recent years, AR has grown rapidly and is used in various fields: education, retail, industry, healthcare, to entertainment. However, not all ARs work in the same way. Based on the technology and the way it interacts, AR can be classified into several main types. 

1.Marker-Based AR 

Marker-Based AR uses visual markers (such as QR codes, images, or custom symbols) to bring out digital objects. 

When the camera detects a marker, the system will: 

  • Identify patterns 
  • Calculating positions 
  • Display a 3D object on top of a marker 

Example: 

  • Interactive brochures 
  • AR education card 
  • AR Books 

This type is widely used in education and marketing because it is easy to implement and cheap. 

2.Markerless AR 

Markerless AR does not require a physical marker. The system uses: 

  • GPS 
  • Accelerometer 
  • Gyroscope 
  • Computer vision 

to determine the position of digital objects in the real world. 

This is the type of AR used by: 

  • Pokémon GO 
  • Google Live View 
  • AR navigation 

Markerless AR allows for a more natural and flexible experience. 

3.Projection-Based AR 

Projection-Based AR projects light or images directly onto a physical surface, not onto a screen. 

The system will: 

  • Projecting visuals 
  • Detecting hand or object interactions 
  • Provide real-time responses 

Example: 

  • Interactive Tables 
  • Industrial simulator 
  • Technology exhibition 

This type is widely used in design, manufacturing, and training. 

4.Superimposition-Based AR 

This type replaces part or all of the display of real objects with a digital version. 

For example: 

  • Displays the version of the machine that has been repaired 
  • Visualization of the body organs above the patient’s body 

Used in: 

  • Medical 
  • Maintenance 
  • Engineering 

AR superimposition helps users understand the condition and structure of objects more clearly. 

5.Location-Based AR 

Location-Based AR combines location data with digital visuals. 

AR will appear only in certain places. 

Example: 

  • LA tourism guide 
  • AR museum 
  • Location-based AR games 

This type creates an experience that is tied to physical space. 

 6.Wearable AR 

Wearable AR uses devices such as: 

  • Smart glasses 
  • Head-mounted display 
  • AR headset 

Users don’t need to hold the phone. 

Used in: 

  • Industry 
  • Military 
  • Logistics 
  • Health 

This is the direction of the future of more hands-free and immersive AR.
