institutions and citizens.
• Based in the IT-city Katrinebjerg in Aarhus and the IT-University
in Copenhagen.

4. Click to edit Masterparadigm
The current app title style
• Social networking, games,
photography,…
• Simple focused apps
• Rich in detail
• Rich interaction
– Touch and gesture based
• Lot of attention to design and detail
• However, apps are often monolithic
• Developed for their own digital niche
• Not much integration with the user’s
world

6. Click to edit Master “smart” devices
Smartphones as title style
• Very powerful devices
– Quad core CPUs, Dedicated GPUs, etc
• Many physical sensors:
– Camera (ID, Object tracking, light levels)
– Microphone (audio levels, voice commands)
– 3G/4G (location, proximity)
– Bluetooth (location, proximity)
– Wi-Fi (location, proximity)
– Accelerometer (movement)
– Compass (direction)
– GPS (location)
– Gyroscope (movement)
– NFC/RFID (identification)
– …

7. Digital-physical apps
Click to edit Master title style
• Next generation apps should utilize this technology
• Apps should be aware of the user’s context
– Adapt functionality and application behavior
– Present and filter relevant information
– Allow the user to control and interact with the surroundings
• Not an “easy” task of course…
• So new software tools and ideas are needed

8. 1. Overlaying the world
Click to edit Master title style
November 25, 2012 Page 8
Minority Report (2002)
9. Location-based AR
Click to edit Master title style
• Digital Threads (Digitale Tråde)
• Location-based augmented reality
– GPS, Accelerometer, Compass
• Developed with Museum
Midtjylland
• Displays excavation sites and
historical buildings in the landscape
• Challenge:
– Turned out to be “complex” to
implement
– Accuracy depends on the
smartphone sensors
November 25, 2012 Page 9
10. Vision based AR
Click to edit Master title style
Storm P Museum • Storm P Museum
• Skovgaard Museum
• Developed for Redia
– http://www.redia.dk/
• Vision based
• Based on feature models
Skovgaard Museum • Overlays graphics, animation
and control over the camera
image.
• Challenge:
– Very dependent on light conditions
November 25, 2012 Page 10 – Scalability: hard to model everything
11. Challenges for mobile augmented reality
Click to edit Master title style
• AR is “complex” to implement
– Sensor fusion
– Advanced tracking
• Location based augmented reality is only as
good as the accuracy of the mobile phone's
sensors
• Vision based augmented reality requires
models and a lot of computation
– (i.e. you can’t model the entire world)
• But, when you combine the two:
– You can filter the models based on the user’s
location and orientation!
– Can potentially make it much easier to create
advanced digital-physical visualization apps!

12. 2. Interacting with objects and
Click to edit Master title style
controlling the environment
• Idea: using the smartphone as a information and control
device for the environment.
– Smartphones can be used to identify physical objects
– Using the camera, GPS, NFC, etc
– Apps can present relevant information to the user
– Smartphones can adapt to the environment,
– eg. as an advanced and dynamic remote control

14. Interacting with objects –
Click to edit Master title style next generation
• RFID (Radio Frequence Identifier)
• Radio based tag
• Can be hidden inside object
– No camera needed
• Support simple “swipe”-based
interaction
• Killer app: mobile payment
• App: AudioMove.org
• Developed for Katapult and KMD
• Audio-based theater for system
developers
• User scans props to hear the story
November 25, 2012 Page 14
15. Controlling the environment
Click to edit Master title style
• Car controller, Mercedes and B&O
• Mercedes-Benz Viano Vision Diamond
• Standard iPhone / iPad is used as
control device
– Television, audio system, lights, …
– Different scenes:
• Office,
cinema,
concert,
internet,
live or relax

3. Apps as glue for digital
• Not all interaction has to go through the smartphone
• Other forms of interaction:
– Interactive installations in the city
– Installations in the home (heat control)
– Fitness or life style equipment
• But smartphone apps may be the glue or hub that
connects it all…

17. Health monitors
Click to edit Master title style
• Jawbone UP
– “Use the UP wristband
and iPhone app to track
your steps, distance,
calories burned, pace,
intensity level, active vs
inactive time, GPS routes
and more.

• All interaction is through a more natural interface but
heavy lifting and data communication is handled by the
smartphone apps

Think of it as a Livestrong bracelet that keeps track of your body’s inner goings-on while you wear it. Working in conjunction with your iPhone, Up tracks your daily physical activity, monitors your sleep habits and quality, and also acts as a meal tracking aide. All of the data is stored within the app on your phone, synced by plugging Up’s 3.5mm jack into the iPhone earbud port.
