Introduction
• Augmented reality helps present information succinctly.
• AR presents a view of the real, physical world that incorporates additional information to augment this view.
• Augmented-reality applications commonly use markers for detecting and tracking virtual objects.

AR Architecture
![Page 8: Lab Meeting - 20141028 - Augmented Reality Interfaces](https://reader036.vdocuments.site/reader036/viewer/2022070323/559826501a28abf5488b4811/html5/thumbnails/8.jpg)
Realizing Augmented Reality
• Enabling Technologies• Needs suitable sensors
• Fine-grained geolocation
• Image recognition
• Trigger matching and image augmentation• Image processing
• Subsequent user interaction• Gaze tracking, touch, gesture and speech recognition

Toward an AR App Taxonomy
• Trigger• Location trigger – Nokia City Lens
• UPC symbol – Amazon Mobile App
• Face recognition – Recognizr
• Interactivity• No interactivity – road names augmented on a satellite image
• Low interactivity – GPS Drive, Walk app
• High interactivity – advertisement icons

Toward an AR App Taconomy
• User interface modalities• Gesture
• Gaze
• Speech – Google Glass
• Touch - joysticks

Opportunities and Prospects
• Usability Challenges• Overloading users
• Can the user tell the difference between reality and the augmentation?
• Is the augmentation aligned with reality?
• How can a user transition between AR and traditional apps?
• Social Challenges
• Business Models

Conclusion
• The AR apps we see today are little more than proofs of concept, but they do succeed in showing the potential of making augmented reality a reality.
