1. Emulating the Future with/of Pervasive Computing R&D 1 Laurent Ciarletta LORIA & ENSMN Pervasive 2005, Workshop “What make for good application-led research in ubiquitous computing?”

2. Emulating the Future with/of Pervasive Computing R&D 2 Visibility of Ubicomp : News and Internet Browsing on Pervasive Computing Applications  PDAs, smart phones, WiFi, 3G, RFID : where/what are pervasive applications?  Smart fridge, smart cars, robotic hovers/mowers : where are the mainstream offers, where is the interoperability?  Weather /mood connected lamp, (AR) PacMan in the streets of Taiwan: where is the public?  Etc. Are we there yet? Why?

3. Emulating the Future with/of Pervasive Computing R&D 3 Personal Background and Experience: Pervasive Computing Work at NIST  Application-led R&D Building test-bed & applications Collaborating with industry and academics (networking, systems, software, embedded systems, AI)  Standardization Evaluation: metrics, tools Reference implementation Modeling and simulation 1998-2002

4. Emulating the Future with/of Pervasive Computing R&D 4 Pervasive Computing is User-centric  User is part of the LPC model  New metrics Usability Reliability Service vs. Cost  Various users: Consumer/client/patient Disabled/Senior/Child John Doe (is not a designer, nor a researcher!)

5. Emulating the Future with/of Pervasive Computing R&D 5 From Application-led R&D to Emulation: Aroma Smart Conference Room, EXiST  Resource consuming : Money-wise Time and energy  Moderately rewarding Demo effect Emerging technologies Quick prototyping techniques Maintenance issue Quickly obsolete (although) Non usable, lost when gone  Isolated, can’t keep up with the big players  -> Emulation/Simulation EXiST 1999-2000

6. Emulating the Future with/of Pervasive Computing R&D 6 The 2 Faces of Emulation  Existing Bricks Architectures  In computer science and other scientific fields To emulate: (Computer Science) To imitate the function of another system (not necessary at the same speed) Effort or ambition to equal or surpass another To strive to equal/match or excel, especially through imitation Hardware emulators Network emulators Virtual Reality Toolkit Tangible User Interface Intelligent agents DIS HLA Missing parts ?

7. Emulating the Future with/of Pervasive Computing R&D 7 Real Test-beds vs. Emulation Real Test-bedEmulation/simulation Expensive Difficult to set up/maintain Limited scale Quick obsolescence Fixed location Replay difficult Class of applications - oriented Safety and privacy issues for specific applications Reduced cost Quick set-up, prototyping, development Scalability Consistent/coherent replay Safe Reality check!It’s not reality Reality is more complex Modeling is difficult Real-time is even more difficult Validity?

8. Emulating the Future with/of Pervasive Computing R&D 8 Tools for Application-led Development Tools for the Community  Development tool (toolkit/commonly agreed on architecture) Large-scale / distributed Mixed-mode: Integration of real applications, devices, architecture with emulation/simulation Scenario-based Methodology Allows: Test, evaluation, incremental development Emulation of creativity, showroom  Model/classification, for cooperation between Research teams Communities  Large scale « open » community test-bed: Pervasive Computing Bone  Taskforce / workgroup Common tools Standards Mailing list/ Forum Publicize/advertise What features would you like to see? Developing applications shouldn’t/doesn’t imply lots of money and hardware and rebuilding almost everything from scratch
