IntroductionUbiquitous information and communicationExperiences in deploying ubiquitous systemsResearch challengesSummary
IntroductionIntroduction
Mark Weiser’s vision of Ubiquitous Computing in 1991
– Still futuristic today
Many technical and sociological challenges– Creating system beyond mere laboratory prototypes
Discuss research challenges!!
Ubiquitous information and Ubiquitous information and communicationcommunication
Technology has advanced towards Ubiquitous computing
– Global Positioning System (GPS)– Radio Frequency Identification (RFID)
Striking developments– The emergence of the Web
• a global information and service resource
– Mobile telephony• Widespread adoption

Research ChallengesResearch Challenges
Component interaction– Should be designed in an open and
extensible manner
Adaptation and Contextual sensitivity– might reconfigure applications involving
multiple components
Appropriate management mechanism– Unlikely occurs within the context of a single
administrative domain
Research ChallengesResearch Challenges
Component association and Task analysis– Accurately determine a user’s task and
intention– Develop associations between components
Viable economic models– A single “killer” application is unsuccessful– Many small contributions from applications
that use the component
Research ChallengesResearch Challenges
User interface integration– Need coordination between applications – To ensure a reasonable user interface
Privacy and Security– Empower users to evaluate the trade-off
• Protection of privacy VS. improved service
– Legislation must define the boundaries
SummarySummary
Technology has advanced towards UbiComp– GPS, RFID, Web, Mobile Phone
Many researches for developing prototypes
Research Challenges for Ubiquitous Computing– Technical and sociological challenges– Mainly focus on “integration”
