Imagine a worker being able to know
when all his colleagues are available,
where they are, and what they are
doing and to be able to interact with
them on the colleagues’ own terms
anytime, anywhere?

Human communication
1995
“Programvaruteknik”
(CDT)
Face to Face
Electronic Meeting
Dick’s vision
The Electronic Meeting
1998 – Marratech spin-off from Media Technology
E-Meetings
1. Meetings via the net
2. Net-based education
•
•
One to many with questions back
Group discussions
3. E-corridor
•
•
24-hours per day
Sense of presence within a group
Meetings via the net
• Different meeting patterns
• Planned meetings
• Project meetings, administrative meetings,
discussion meetings
• Spontaneous meetings
• One to one
• Group
• With or without an agenda
Advantages with e-meetings
• Participants can do other things while they
wait for the meeting to start.
– Somebody is always late
• Independent of locality
• Partly time independent
– Recording
Advantages…
• One ear participation
• Minutes are created in real-time
– Everybody can see the results
– Available directly after the meeting
Net-based Education
Lectures
Group work
Lab-assistance
E-corridor
eKorridoren
Net “addiction” * 2
• Must have network access
– Internet...
– Phone…
• You get dependant on using the tools!
Augmented meetings
•
•
•
•
•
Extend physical meetings
All present part of local e-meeting
Additional value to meeting
Archiving
Conferences…
Recording!
• All meetings can be archived
• Identical copy!
• Access for students
– Exam study
– Exam correction!!!
• Old Courses
– Own education
– Advertisement via free courses (student recruiting)
– Transfer between teachers
History online
• Record everything – all the time!
Always Best Communication
Always Best Communication - ABC
• Users want to communicate with each
other
– Any place
– Any time
– Any device
• How can we utilize wireless networks in
supporting ABC?
Simple Scenario
• Session and device mobility
– A user is late for an online meeting
• The system knows this from the user’s calendar
– The system automatically dials the user’s
mobile phone
• Audio participation
Step 2
– The user reaches her office
• This is noted by location awareness
– The system automatically joins the online
meeting and ask the user where she wants
the audio
• In the mobile, PC audio or desktop phone?
• User selects desktop phone on the PC screen and
the call is transferred from the mobile.
Problems
• How to detect locality with good enough
precision?
• How to swap between different wireless
and fixed carriers?
– Carrier mobility
• How to swap between devices
– Session mobility
• How to keep the current session running?
Effortless Communication
How can human communication be
improved?
• Improved group feeling
• What does users perceive as better?
– Sound- and image quality
– New media sources
• How can communication be adapted to
different network conditions?
– ABC
• How to handle new mobile devices?
Scalability
Mobile e-meetings
Scalable Group Communication
Nomadic communication
Wearable systems
• How to create usable wearable systems?
• Combination of existing hardware
• User Interface
– Interaction with devices in the vicinity
– Change of screen (handheld <> HMD)
– Dynamic change of media format
• (speech – text)
Eventcasting
Use of wearable systems
• Care (in the home, elders)
– Nurse sees journal in the eye monitor
– Patient communicates with doctor using flat
screen
– Doctor comments privately to the nurse
iceBear
Wearable and Tele-Presence
• Participate through other eyes
• Mediated Communication
– Knowledgeable beacon
Applications for mobility,
not applications used
in a mobile setting!
Situation aware systems
• Systems that know what is happening
around them
• User state
– Stress, position, calendar, email queue,
time/day
• How to gather this information?
• How to present it?
– Locally vs. other users -> privacy!!!
• How to use this information?
Applied Research
• Scenario driven research
• Dual results:
– Academic results
– Prototypes (running software)
• The results should be used!
It should just work!
Vision:
Thelma
Thelma
• Better spontaneous real-time group
support via the net
Standard web technology
+ Ajax / Web 2.0
+ Conferencing
• Allow for web conferencing where place is
defined by the web
Light vs. Heavy clients
• Light weight
– Web version – Thelma
– Separate tools
– Connected to certain web-areas
– Spontaneous interaction
• Heavy weight
– Downloaded version – Marratech
– Webstart vs . Installed
Problems
• How to make it general?
• Media synchronization?
• Heavier media support?
– Microphones, video cameras
• User interface when many join / leave
Vision:
Ubiquitous Human
Communication
Ubiquitous Human Communication
• Imagine rich media sensors
– Includes audio in (microphone) and audio out
(speaker)
• but not necessarily in the same device
– Includes video in (camera) and video out
(display)
• but not necessarily in the same device
– Not all in same device (might be 4 different)
– “Cheap”
– Doesn’t have to run on batteries
– WLAN
Available everywhere
• We put these all over a work place
– Offices
– Corridors
– Homes
• Use together with good enough positioning
of all users
• Allow for “free” communication anywhere
Ubiquitous Human Communication
Problems
• How to make the sensors cheap
• Distributed echo canceling/suppression
and multi-channel audio playback
• Multi-view video grabbing presented
– Several video views to multiple video display
devices on the other side.
Problems…
• WLAN model when using high quality
video feeds (sustained 1-25Mbps per
video channel and several channels).
• Power?
– Perhaps skip WLAN and go for ethernet +
power over ethernet instead?
Collaborative Work Environments
• Mix everything already mentioned
–
–
–
–
–
Smart buildings
Distributed team support
Maintenance
Mobile Communication (4G)
Synchronous plus asynchronous communication
• Conference: CWE-Europe
– Brussels 2006 May 10-11
– Luleå 2007 June 14-15
