3. What is Augmented Reality (AR)?
 Variation of Virtual Reality (VR)
 AR extends perception; VR replaces it
 Key characteristics (Azuma,1997):
 Combines real and virtual
 Interactive in real time
 Registered in 3D
 Currently often seen a bit more
relaxed, esp. with regards to
3D registration

7. Example 2: Timewarp
 Mobile AR Game
 Playful environment for learning about the
historical background of cities
 Here: Cologne
 Quest for the vanished
„Heinzelmännchen“ of Cologne in
different epoches
 Audio visual design to give historical
impression
 Participants aid Heinzelmännchen
 Live for a month in early 2010
 Big press coverage

8. Reducing the effort of staging
 Huge efforts for staging Gandhara,
Time Warp, and similar experiences
Mobile
 Having a venue Location
 Writing the software
 Designing the content Authoring
 Providing the hardware
 Orchestrating the experience
 ...
Ease of use
 Too much effort for high impact
 Democratisation of creation

9. TOTEM – Theories and Tools for Distributed Authoring of
Mobile Mixed Reality Games
 Project start: September 2009
 3 year duration
 Partner: Fraunhofer FIT, Germany & Carnot Institut
TELECOM EURECOM, France
 Main Goals:
 Provide tools for creation and orchestration of
Mobile Mixed Reality Games
 Build a community around these tools
 Explore game design and presence research
questions concerning such games

10. From complex to simple
Time Warp
Geocaching
Complex
• Limited time Simple
• Expensive
• Few users • Always on
• Affordable
• Mass market

11. Tidy City, a mixed-reality scavenger hunt
 The world is in confusion. Landmarks have
become dislocated, cities are in disarray. Players
can tidy up by picking up misplaced items and
bring them back to their proper locations. //
Michael Straeubig
 The name of the game is a reference to the
project “tidy up art” of the Swiss artist Ursus
Wehrli
 Developed as part of the TOTEM project on
authoring mobile mixed reality games

12.  Solve location-based riddles
 Overview
 Pick-up
 Discover
 Solve & score

13.  Preparing for a workshop in-situ
with the location survey tool
 Finishing at the desktop using
the web-based authoring system
