History
 Created 1995 as Software Engineering as
part of CDT
 Long history of working with real-time IPbased communication
 mStar – Marratech AB
 Changed into formal research area 2002
 First PhD 1999, second 2002
 (Computer Science – “Datalogi”)
Current Research
 Human Communication
 Always best connected (ABC)
 Mobile wearable systems (Borderland)
 Context-Aware systems (Alipes)
Human Communication
 How can human communication via
electronic means be enhanced?
 Then: Technology view
 Now: User view
 What does the user perceive as better ?
 Different from situation to situation!
 Primarily group communication
 Scalable media distribution (Rome)
 EFamily
Scalable Group Communication
mPocketPro
Mobile
E-Meetings
Always Best Connected
 The user should be able to move between
different networks
 Shouldn’t need to reconfigure
applications/computers when switching
networks or network operators
 Challenge: Make usage of mobile internet
useable
 It should just work!

Wearable Computing
 How to create wearable systems for
human communication
 Not building new hardware
 Combining existing components
 User interface issues
 Device Interaction, switching screens
(handheld to HMD), switching media (text to
audio etc).
 Application migration
Borderland
Wearable
Computing
Context Aware Systems
 Systems that are aware of their surrounding
 The user “state”
 Stressed
 How to gather this information
 How to present that information to
 System
 Other humans
 How to utilize this information in other ways.
 Dr. Kåre Synnes
Applied Research in Action!
 Scenario driven applied research
 Results:
 Prototypes (running
software/systems)
 Good academic results
 We want the results to be utilized!
It should just work!
Future Interest
1. Scalable really high quality
media distribution
 10Kbps – 270 Gbps
 Anywhere, Any device
2. Shared consumption
 Consume media at several
locations with your friends
 Group viewing
More interest…
3. Mobile Media Production:
 How to produce high quality
media “on the go”?
 Quick setup
 Combination of (remotely) stored
and real-time media
 Directed reruns based on cached
media at the receiver
 Events, education, meetings
