3. Overview
 Introduction & Abstract
 Background
 Pervasive Augmented Reality
 Methodology
 Survey of Existing Approaches
 Future Scope

4. Introduction
 Augmented Reality – overlay of digital information
 Normally, for a single purpose and for a short time
 Pervasive/Ubiquitous Computing
 Continuous AR Experience -> PAR

5. Background
 Characteristics of AR:
- Combination of Virtual and Physical Elements
- Interactive in Real-time
- Visible in 3D
 Components of AR:
- Tracking Component
- Rendering Component
- Interaction Component
 Classifications Of AR:
- Stationary
- Mobile

6. Context Awareness
 Gather information about its environment at any
given time and adapt behaviours accordingly.
 Primary Context Factors:
- Location
- Identity
- Activity
- Time

7. Pervasive Augmented
Reality
 Moving from AR to PAR – from specific purposes
to an always-accessible, universal information
and communication interface.
 Integrating Larger group of Factors
 Continuous Information Overlay for Everyone.
 PAR characteristics:
- Continuous
- Present Everywhere
- Universal Interface

8. AR VS PAR
Augmented Reality Pervasive Augmented Reality
Scattered Universal
User Controlled Context Controlled
General Purpose Tailored for Each User
Task Driven Context Driven

9. Methodology
 Classifying into Context Sources & Targets
 Context Sources:
- Human Factor - Personalised for Each User
- Environmental Factor - Infrastructure
- System Factor – Computation, Battery Consumption
 Context Targets:
- Providing Data According to the need

10. Survey & Result
 Different System Inputs:
- Hybrid UI (AR + VR)
- Smart Phones
- Wearables
 Different System Configurations:
- Data Integration – sensors & devices
- Computation Modes – local & remote
 Different System Outputs:
- Content – Routes, Displays
- Presentation – Precision Overlay, Selected Items

11. Future Scope
 Low Power and Computation Usage by AR
interface
 Fast and Customisable HUD
 Shared AR
 Socially aware with Privacy
