AR2.0, UVR is H-Green IT
GHIT, Human-centered Green IT
 To improve human wellness and happiness
 To reduce the use of hazardous materials, maximize energy
efficiency during the product's lifetime, and promote the
recyclability or biodegradability of defunct products and
factory waste.

Virtual vs. Augmented Reality
Virtual Reality (out there):
 Puts people in a computer-generated world
Augmented Reality (here & now):
 Puts virtual content in a real physical world


What is Augmented Reality?
P. Milgram's Reality-Virtuality Continuum
[94]

R.Azuma's definition on AR [97]
 combines real and virtual
 is interactive in real time
 is registered in real 3D world

AR Applications
Possible Applications
 Consumer products, furniture, decoration
 Construction, houses, apartments
 Augmented ads, packages, products
 Entertainment, infotainment, games
 Fashion, trends, digital arts
 Sharing by communities
 Maintenance & Repair
 Medical, training

Mobile AR
Smart Phone for Physical Interaction
 Connecting People, Places, Things, and Ideas
• The environment as part of the interface
• Camera phones as “bridging” devices
• Integration with the user’s activities
 Click real world !!!
 AR Apps in iPhone AppStore
• 54 in July, 2010 and 605 total. (260K Apps in Oct., 2010)

Social AR
Issues of Social AR
 Physical self along with a digital profile
 Unauthorized Augmented Advertising
 Privacy: Augmented Behavioral Targeting
 Safety: Physical danger
 Spam


Social AR: Issues

What’s ubiquitous VR?
Ubiquitous VR for DigiLog Life (Woo)
 3D Link between dual (real & virtual) spaces with additional
information
 CoI (Context-of-Interest) Augmentation, not just sight:
sound, haptics, smell, taste, etc.
 Bidirectional UI/UX for H2H/H2S/S2H/S2S communication in
dual spaces
Virtual space

Seamless U-Content

General Space Social Networks


What’s Ubiquitous VR?
Core of UVR
 CoI localization
 Ubiquitous augmentation
 Smart UI for organic visualization
 Networking and public DB access
 3D Interaction & collaboration
 U-VR ecosystem with SNS, LBS, CaS


Ubiquitous VR
Platform for DigiLog Experience
 Augmented Content is a King, then Context is a
Queen consort controlling the King! • Multicore/GPGPU
• Object
How to avoiding the fate of recognition/tracking
VR? • Light source estimation
"to look for DigiLog, the • Physics engine
• AI engine
intersections between the
digital world (3D, SNS) and
analog world (CoI)”

• Interaction
• CoI-aware • Mash-up authoring
• Environmental context: • SNS
• User context: knowledge, experience, • Extension of human
preference perception
• Just-in-time visualization


UVR Authoring & Mash-up
Augmented World Builder with ARWand
 ARWand is a smartphone-based 3D user interface for a
wearable augmented reality environment


UVR Interaction
Organic AR UI
 Input Equals Output:
• Where the space is the input/output
 Function Equals Form:
• Where the AR output can take on any shape
 Form Follows Flow:
• Where AR output can change its shape


What’s Next?
What to Expect in 2013?
 Qualcomm snapdragon 800: 2.3 GHz Quad Krait CPU
 Vuzix M-100, Google glasses, Verizon glasses, etc.
Trans-Spaces with Wearable CAMAR 2.0
 <Open + Participate + Share>
 LBS + In-situ Mashup + SNS + CAMAR for sustainable AR
eco-system
