Define Wi-Fi

• Wi-Fi does not stand for Wireless Fidelity
• It is not an acronym. There is no meaning.
• As a trademark, it isnt allowed to have a
  pre-existing meaning in the realm in which it is
  registered
• The Wi-FI Alliance wanted something catcher than
  IEEE 802.11b Direct Sequence
• hired Interbrand to come up with the name and
  logo

Why Wi-Fi Warchalking died

• "Warchalking is the practice of marking a series
  of symbols on sidewalks and walls to indicate
  nearby wireless access. That way, other computer
  users can pop open their laptops and connect to
  the Internet wirelessly."
• Challenges
• Grassroots effort
• Amateurs
• Defacing buildings is illegal
• Requires maintenance
• Wi-Fi Logo ?

Define UbiComp

• UbiComp Ubiquitous Computing
• Mark Weiser coined the term in the late 80s
• UbiComp forces the computer to live out here in
  the world with people
• Also known as Pervasive Computing

Define SmartMobs

• Consist of people who are able to act in concert
  even if they dont know each other. They emerge
  when communication and computing technologies
  amplify human talents for cooperation
• Impacts from SmartMobs have been /-
• Location-based matchmaking
• Organized gang killing using text messages
• SmartMob Technologies
• Mobile communication devices
• Pervasive Computing

System Directions for Pervasive Computing

• Pervasive computing focuses on deploying smart
  devices through our working living spaces

The infrastructure necessary to seamlessly and
ubiquitously provide applications is almost a
reality
There are difficulties when designing, building,
and deploying applications in a pervasive
computing environment
Grimm, R., Davis, J., Hendrickson, B., Lemar, E.,
et al. (2001)

System Directions for Pervasive Computing

• Argument Existing approaches to distributed
  computing are flawed along three Fault Lines when
  applied to pervasive computing.
• Application data and functionality need to be
  kept separate
• Applications need to be able to acquire any
  resource they need at any time so that they can
  continuously provide their service in a highly
  dynamic environment
• Pervasive computing requires a common system
  platform allowing applications to run across a
  range of devices

Grimm, R., Davis, J., Hendrickson, B., Lemar, E.,
et al. (2001)

T Spaces The Next Wave

• A network middleware package for the new age of
  ubiquitous computing
• Enables communication between applications and
  devices in a pervasive computing environment
• To connect all devices we must have a common
  language platform on which to run

FieldWise A Mobile Knowledge Management
Architecture

• KM, Mobility and CSCW
• Findings from empirical studies fieldwork
• Peoples tasks are time critical and driven by
  deadlines
• Results rely on the creativity of autonomous, but
  interrelated people
• There is a culture of co-operation and sharing of
  knowledge amongst people
• People are mobile and distributed
