Study Notes
What is Augmented Reality?
- Combines the view of the real environment with virtual content presented through computer graphics.
- Ensures virtual content is aligned and registered with real objects.
- Allows users to overlay computer-generated content in the real world.
- Typically done in real-time and in semantic context with environmental elements.
Types of Reality
- Virtual Reality (VR): fully immersive, tricks senses into thinking it's a different environment or world.
- Augmented Reality (AR): combines the view of the real environment with virtual content.
- Mixed Reality (MR): integrates and interacts with the real-world.
- Extended Reality (XR): a universal term inclusive of all real-and-virtual combined environments and human-machine interactions.
Architecture of AR Systems
- Infrastructure Tracker Unit: collects data from the real world, sends it to the Processing Unit.
- Processing Unit: mixes virtual content with real content and sends the result to the Video Out module of the Visual Unit.
- Visual Unit: can be classified into two types of systems - Video see-through and Optical see-through.
Challenges of AR
- HMDs (Head Mounted Displays) lack in ergonomics, are expensive, and have limited mobility due to size and connectivity features.
- Collision: difficulty to interact with multiple points in different depths causes collisions between interactive zones.
Applications of AR
- Engineering Design: 3D prototyping, design augmented with computer-generated images.
- Manufacturing, Maintenance, and Repair: augmented images of equipment with annotations and information pertinent to repair.
- Collaborative AR: addresses two major issues with collaboration, enhancing practice by supporting remote and co-located activities.
Learn about the infrastructure and components of Augmented Reality systems, including the Infrastructure Tracker Unit and Processor Unit, and their role in integrating virtual content with the real world.
