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.
Introduction
(a) an ARToolKit-type marker
(b) theEiffel Tower
(c) a wine glass
(d) a beer bottle.
Examples of Augmented Reality
• Navigation
• Commerce
• Captioning
Nonexamples of Augmented Reality
• Immersive virtual reality (IVR)
• Photo editing
• Augmented media
• Quick Response (QR) codes
AR Architecture
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
Realizing Augmented Reality
• Enabling Technologies• AR presupposes a substantial information infrastructure
• Cloud services
• AR requires significant computing and communications infrastructure
Realizing Augmented Reality
• User Platforms – cloud services backdrop• Mobile phones
• High-quality cameras
• Geolocation capabilities
• Other sensors
• Sufficient computing
• Communications capabilities
Realizing Augmented Reality
• User Platforms – cloud services backdrop• Vehicles - windshield
• Practically unlimited (electric) power
• Support powerful computing and communications
• Wearable computers – Google Glass• Numerous sensors
• Close access to user
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.
