Overview • Clarify terms • Review related readings • References
Define: Wi-Fi • Wi-Fi does not stand for “Wireless Fidelity” • It is not an acronym. There is no meaning. • As a trademark, it isn’t 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 • More WiFi news: Wi-Fi Net News
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 80’s • 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 don’t 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 • More information: SmartMobs, Howard Rheingold
Pervasive computing focuses on deploying smart devices through our working & living spaces System Directions for Pervasive Computing 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 runacross 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 • Lehman, T., McLaughry, S.W., Wycko, P. (1999)
FieldWise: A Mobile Knowledge Management Architecture • KM, Mobility and CSCW • Findings from empirical studies & fieldwork: • People’s 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 • Fagrell, H., Forsberg, K., Sanneblad, J.. (2000)
