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.
