![1] MARKER-BASED AR
10
âą This type uses physical markers, like QR
codes or special images, which are
recognized by a device's camera. Once
detected, digital content is overlaid onto or
around the marker.](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/75/Augmemted-reality-and-it-s-fundamentals-10-2048.jpg)
![2] MARKERLESS AR
11
âą Also known as location-based AR, it doesn't
rely on markers but instead uses GPS, or
other sensors to place digital content based
on the user's location or movement.](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/75/Augmemted-reality-and-it-s-fundamentals-11-2048.jpg)

3] PROJECTION-
BASED AR
âą This type involves projecting digital
content directly onto physical surfaces.
The projected images are interactive
and respond to user input](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/75/Augmemted-reality-and-it-s-fundamentals-12-2048.jpg)

4] SUPERIMPOSITION-
BASED AR
âą This type replaces or enhances parts of the
real-world view with digital content. It can
change how the user perceives reality by
replacing or adding digital elements.](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/75/Augmemted-reality-and-it-s-fundamentals-13-2048.jpg)

OUTLINING
AR
âą This technique focuses on enhancing the
visibility of objects in the real world by outlining
them or highlighting certain features, often
used in industrial applications.
âą Highlighting an objectâs edges to make it easier
to identify or track in real-time.](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/75/Augmemted-reality-and-it-s-fundamentals-14-2048.jpg)

- 2. OVERVI EW 2 âą Introduction âą KeyComponents âą History âą Key characteristics âą Different Types of ar
- 3. WHAT IS AUGMENTEDREALI (AR)? âą Augmented Reality (AR) is a technology that overlays digital content on the real-world environment, providing a composite view that enhances a personâs interaction with the world around them 3

- 6. HARDWARE SOFTWARE AR Devices: Smartphones, tablets,AR glasses (e.g., Microsoft HoloLens, Magic Leap), and headsets. These devices display augmented content by overlaying it on the real world. Sensors and Cameras: These capture the real- world environment and track the user's position and movement Processors: Devices need powerful CPUs and GPUs to render AR content in real time. AR Software Development Kits (SDKs): Tools like ARKit (Apple), ARCore (Google), SLAM Technology: Ensures accurate mapping of the environment and positioning of AR objects in real-time. 6
- 7. HISTORY OF AUGMENTED REALITY 1960s-1980s: Earlyconcepts, like Sensorama (1962) and Ivan Sutherland's Sword of Damocles (1968), laid the groundwork for immersive technologies. 2000s: The release of ARToolkit (2000) and apps like Layar (2008) brought AR to the mobile space. 2010s: Google Glass (2013) and Pokémon GO (2016) made AR mainstream, while Apple and Google launched ARKit and ARCore for app development. 2020s: AR is now used in industries like healthcare and education, with AR glasses and AI integration shaping its future. AR has transitioned from experimental tech to a mainstream tool with growing applications across various sectors. 7
- 8. 8 âą Integration withthe Physical World: Digital content interacts with the real environment. âą Contextual Awareness: AR adapts based on location or surroundings. âą 3D Content: Often uses 3D models for a more immersive experience. âą Tracking and Mapping: Uses sensors to track and align virtual content. âą Device Dependent: Requires devices like smartphones, tablets, or AR glasses. âą User-Centric: Allows interaction via touch, gestures, or voice. âą Location-Based: Provides location-specific experiences.
