![1] MARKER-BASED AR
10
• 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-250318131657-771f8ab4/85/Augmemted-reality-and-it-s-fundamentals-10-320.jpg)
![2] MARKERLESS AR
11
• 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-250318131657-771f8ab4/85/Augmemted-reality-and-it-s-fundamentals-11-320.jpg)

3] PROJECTION-
BASED AR
• 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-250318131657-771f8ab4/85/Augmemted-reality-and-it-s-fundamentals-12-320.jpg)

4] SUPERIMPOSITION-
BASED AR
• 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-250318131657-771f8ab4/85/Augmemted-reality-and-it-s-fundamentals-13-320.jpg)

OUTLINING
AR
• 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.
• Highlighting an object’s edges to make it easier
to identify or track in real-time.](https://image.slidesharecdn.com/augmemtedreality-250318131657-771f8ab4/85/Augmemted-reality-and-it-s-fundamentals-14-320.jpg)

- 1. AUGMEN TED REALI TY 1 • NAME : HEER PATEL • ENROLLMENT NO : 12302130501018 • BRANCH : CSD • SUBJECT : SEMINAR(202040404) • ACADEMIC YEAR : 2024-25 • TOPIC : AUGMENTED REALITY
- 2. OVERVI EW 2 • Introduction • Key Components • History • Key characteristics • Different Types of ar
- 3. WHAT IS AUGMENTED REALI (AR)? • Augmented Reality (AR) is a technology that overlays digital content on the real-world environment, providing a composite view that enhances a person’s 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: Early concepts, 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 • Integration with the Physical World: Digital content interacts with the real environment. • Contextual Awareness: AR adapts based on location or surroundings. • 3D Content: Often uses 3D models for a more immersive experience. • Tracking and Mapping: Uses sensors to track and align virtual content. • Device Dependent: Requires devices like smartphones, tablets, or AR glasses. • User-Centric: Allows interaction via touch, gestures, or voice. • Location-Based: Provides location-specific experiences. KEY CHARACTERISTICS OF AR

- 17. POKEMON GO • Pokémon GO,developed by Niantic, is one of the most famous AR applications, allowing players to find and catch virtual Pokémon in the real world. 17
- 18. IKEA • IKEA launched the IKEA Place app, allowing users to visualize furniture in their homes using AR before purchasing. • Customers could view true-to- scale 3D models of products in their rooms, 18
- 19. LENSKART • USING AR TECHNOLOGY, YOU CAN CREATE A 3D MESH OF YOUR FACE WITHIN 5 SECONDS AND TRY ON AS MANY AS 10,000 DESIGNS IN ONE SEATING. 19
- 21. • AR TRANSFORMS TEXTBOOKS INTO INTERACTIVE LEARNING EXPERIENCES BY BRINGING STATIC IMAGES TO LIFE, MAKING LEARNING MORE ENGAGING. EDUCATION AND TRAINING 21
- 22. MILITARY AND DEFENSE • THE MILITARY USES AR FOR REALISTIC TRAINING SIMULATIONS, HELPING SOLDIERS PREPARE FOR REAL- WORLD MISSIONS IN A VIRTUAL ENVIRONMENT. 22
- 23. ARCHITECTURE AND CONSTRUCTION • ARCHITECTS AND DESIGNERS USE AR TO OVERLAY 3D MODELS OF BUILDINGS AND STRUCTURES ONTO PHYSICAL SPACES, HELPING CLIENTS VISUALIZE PLANS BEFORE CONSTRUCTION BEGIN 23
- 24. 24 Healthcar e: • In medicine, AR helps in surgery planning and education. Surgeons can overlay critical information (like 3D models of organs) during procedures. • AR can also assist with patient rehabilitation by providing guided exercises.
- 25. 25 NAVIGATI ON: • AR can improve navigation experiences. • For example, apps can display directions in real time on the road, like showing arrows or points of interest overlaid on the street view.
