This document outlines augmented reality interfaces and applications. It discusses how AR presents additional information that augments the real world view using markers. Examples of AR include navigation, commerce and captioning. The document also describes AR architecture, enabling technologies, user platforms, an app taxonomy based on triggers and interactivity, opportunities and challenges of AR like usability, social impacts, and business models. It concludes that current AR apps are proofs of concept but demonstrate AR's potential to augment reality.
Lab Meeting - 20141028 - Augmented Reality Interfaces
- 1. Augmented Reality Interfaces Internet Computing, IEEE , vol. 17, 12, Dec. 2013 Mona Singh and Munindar P. Singh Advisor : Dr. Jenq-Shiou Leu Student : Bing-SyuanWang Date : 2014/10/28
- 2. Outline • Introduction • Overview • Examples • Architecture • Realizing • AR App Taxonomy • Opportunities and Prospects • Conclusion
- 3. 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.
- 4. Introduction (a) an ARToolKit-type marker (b) theEiffel Tower (c) a wine glass (d) a beer bottle.
- 5. Examples of Augmented Reality • Navigation • Commerce • Captioning
- 6. Nonexamples of Augmented Reality • Immersive virtual reality (IVR) • Photo editing • Augmented media • Quick Response (QR) codes
- 8. 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
- 9. Realizing Augmented Reality • Enabling Technologies • AR presupposes a substantial information infrastructure • Cloud services • AR requires significant computing and communications infrastructure
- 10. Realizing Augmented Reality • User Platforms – cloud services backdrop • Mobile phones • High-quality cameras • Geolocation capabilities • Other sensors • Sufficient computing • Communications capabilities
- 11. 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
- 12. 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
- 13. Toward an AR App Taconomy • User interface modalities • Gesture • Gaze • Speech – Google Glass • Touch - joysticks
- 14. 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
- 15. 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.
