• 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?

E-Meetings

• Meetings via the net
• Net-based education
• One to many with questions back
• Group discussions
• E-corridor
• 24-hours per day
• Sense of presence within a group

9
Conferencing Today

• Phone
• Most common
• H323
• Emerging into SIP based
• Web-conferencing
• Growing the most
• Trends
• Higher video quality

10
Higher Video Quality

• Web-conferencing
• H264
• CIF (352x288, 43),
• SCIF (704x576, 43)
• Going beyond TV-quality
• LifeSize
• HDTV (1280x720, 169)
• Super High Definition, SDH (4096x3112, 43)
• One-way streaming

11
Presence and Mobility
12
Mobility

• No collocation
• Different offices
• In meetings
• Travel
• Home
• Continuous presence
• E-corridor
• Active 24 per day

Scalable Group Communication
16
Always Best Communication
17
Always Best Communication, ABC

• Users want to communicate with each other
• Any place
• Any time
• Any device

18
Simple Scenario

• Session and device mobility
• A user is late for an online meeting
• The system knows this from the users calendar
• The system automatically dials the users mobile
  phone
• Audio participation

19
Step 2

• The user reaches her office
• This is noted by location awareness
• Automatically joins the online meeting
• Asks 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.

20
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?

21
Ubiquitous Human Communication
22
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)

23
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
• Video follows movements
• Ubiquitous Human Communication

24
Problems

• How to make the sensors cheap enough?
• Today old PocketPC devices (HP iPaq)
• 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.

25
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?
• Todays sensor systems targeted towards
• Low bit rate
• Low CPU

26
Mosaic of Realities
27
Mosaic of Realities

• Going even further
• Imagine displays being available everywhere
• Digital advertisements screens
• Office computer screens
• Buy access to these on demand.
• 5 minutes of bottom left corner at the bus stop
• Controlled by remote user, presenter.
• Receiver is only on phone
