1 Beyond Prototypes: Challenges in Deploying Ubiquitous Systems N. Davies and H. Gellersen IEEE pervasive computing, 2002 Presenter: Min Zhang

2 Contents Introduction Ubiquitous information and communication Experiences in deploying ubiquitous systems Research challenges Summary

3 Introduction 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!!

4 Ubiquitous information and communication 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

5 Active Bat System Conducted at AT&T lab. in Cambridge Indoor positioning system – Using sensor and badge

6 Lancaster’s Guide System Provides visitors with tour guide information – Based on visitor’s interest and movement Use – Tablet PC – WLAN deployed around major attractions

7 MediaCup Project University of Karlsruhe, Germany Cups equipped with sensors and wireless communications Not used Someone drinks Someone plays with the cup

8 Research 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

9 Research 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

10 Research 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

11 Summary 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”
