Marker-Based AR

  1. Utilizes Visual Cues: Marker-based AR relies on visual cues, often in the form of QR codes or specific images, which are scanned by a device’s camera to trigger the display of AR content.
  2. Precise Positioning and Orientation: The markers provide exact positioning and orientation to the AR system, enabling it to overlay digital information accurately onto the physical world.
  3. Common in Interactive Learning and Gaming: This type of AR is widely used in educational applications and interactive games, where scanning a marker can bring up 3D models, animations, or additional information.

Markerless AR

  1. Location and Object Recognition: Markerless AR uses a device’s sensors, like GPS, gyroscope, and accelerometer, to detect the user’s location and surroundings, and to overlay AR content accordingly.
  2. Flexible and Diverse Applications: This flexibility allows for a wide range of applications, from AR navigation tools that display directions in real time, to furniture placement apps in interior design.
  3. Enhanced Real-World Interaction: By not relying on predefined markers, this AR provides more dynamic interaction with the real world, such as overlaying digital information onto landscapes or cityscapes based on user location.

Projection-Based AR

  1. Projecting Light onto Physical Surfaces: This AR technology involves projecting artificial light onto real-world surfaces and often allows interaction with this light projection.
  2. Detection of User Interaction: It can detect user interaction with the projection, such as hand movements, enabling a tactile interaction experience without physical touch.
  3. Used in Industrial Design and Medical Training: Projection-based AR is often used in fields like industrial design or medical training, where it can project a virtual keyboard or complex anatomical structures onto surfaces for educational purposes.

Superimposition Based AR

  1. Replaces Original View with an Augmented View: Superimposition-based AR replaces the original view with an augmented, enhanced version by superimposing a digital image over a user’s view of a real object.
  2. Object Recognition Vital: This type of AR heavily relies on object recognition technology to replace or augment the original view with relevant digital information.
  3. Applications in Retail and Medical Imaging: It’s extensively used in retail for virtual try-ons, like seeing furniture in a room, and in medical imaging, where it can superimpose 3D models of organs or systems over a patient’s body for diagnosis or educational purposes.
