1. PLATINE description • Offers a lot of mechanisms that can be used in different contexts: e-learning, co-design, cooperative work, ….. • Software platform used to support remote collaboration among users. • Two main kinds of interactions can be found within collaborative groups: – asynchronous collaboration, that does not require the group members to be present at the same time; – synchronous collaboration, where remote users work at the same time. • PLATINE is mainly devoted to synchronous collaboration. • Developed since 1998, used and deployed in European and French projects. November 17 2009 FOSSa - Grenoble 3

1. PLATINE description • 3 kinds of components – A module for off-line session preparation – Asynchronous session state display with an “asynchronous” chat – Synchronous components • a synchronous session state display • a multi user visioconference • a multipoint chat • an application sharing • a shared whiteboard • a session manager • A PLATINE session is composed of – an asynchronous phase, – a synchronous phase. • Some roles can be defined for one session, and the chairman attribute can be assigned to some roles. • The chairman can manage the synchronous phase of a session. November 17 2009 FOSSa - Grenoble 4

1. PLATINE description • Technical characteristics – Mainly developed using JAVA – External components: • VNC for application sharing • VIC and RAT alternatives for the visioconference tool – Automatic deployment for session participants • JAVA WebStart – Multicast visioconference • Optional reflector module November 17 2009 FOSSa - Grenoble 5

1. PLATINE description • Requirements – Hardware: Pentium (or Centrino) PC minimum 1Ghz, 512 Mbytes RAM – Input/output multimedia devices: webcam, microphone, headset, ... correctly configured and installed. These devices should be recognized by jmstudio (from jmf2.1.1e) – Operating Systems: Windows XP , Fedora , MacOSX – Java : • You can use jre 1.4.2_10 version (less than jre1.5.0 version) . • On your WebStart install, you have to verify the selected jre version • 1.4.2-11 for the Java Runtime Environment (see item J2SEv1.4.2_11) • 2.1.1e for the Java Multimedia Framework November 17 2009 FOSSa - Grenoble 6

2. Use case demonstration • Lab@Future (IST project 2002-2005) objectives: – The experiments realized correspond to learning cases where students gain knowledge by themselves. – Teachers are present in the same student session to answer to students and to remotely help them in case of difficulty. – Difficulties appear in handling the experiment specific tool but also while resolving the problem. • Experiment from the mechatronics domain using the FluidSim software November 17 2009 FOSSa - Grenoble 7

2. Use case demonstration • E-learning use case German FluidSim expert-teacher French teacher office French students LAAS ground floor Multimedia room LAAS first floor November 17 2009 FOSSa - Grenoble 8

2. Use case demonstration • Deployed architecture November 17 2009 FOSSa - Grenoble 9

2. Use case demonstration • Specific tools • Generic – FluidSim (Bremen) communication – Mixed reality platform components (Bremen) – Vic, Rat – VNC server (Bremen) – Session State Display – VNC client November 17 2009 FOSSa - Grenoble 10

User Interface for asynchronous phase User connection to a selected session November 17 2009 FOSSa - Grenoble 12

Specific URL for sync phase User Interface for synchronous phase Synchronous WhiteBoard Session State Display Application Sharing (VNC) JVisioConf November 17 2009 FOSSa - Grenoble 13

2. Use case demonstration November 17 2009 FOSSa - Grenoble 14

3. Technology transfer • Observations • PLATINE is a prototype developed in a research lab in order to demonstrate new transport protocols and new cooperative protocols • No human ressources apart from research projects • We have not found any company to support the industrial completion of the prototype November 17 2009 FOSSa - Grenoble 15

3. Technology transfer • Which result can be transferred ? • Some PLATINE components for academic or industrial partners • Why this choice ? • In the fields of network transport protocols and of computer supported cooperative work (CSCW), the researchers need communicating components • PLATINE components can be used, so we decide to share them easily • Which licence ? • CeCILL-B because it « follows the principle of the popular BSD license and its variants (Apache, X11 or W3C among others). In exchange for strong citation obligations (in all software incorporating a program covered by CeCILL-B and also through a Web site), the author authorizes the reuse of its software without any other constraints.. » http:// www.cecill.info/index.en.html November 17 2009 FOSSa - Grenoble 16

3. Technology transfer • PLATINE website • Source code for the whole PLATINE • Users guides: install and admin and user guidelines http://www.laas.fr/PLATINE November 17 2009 FOSSa - Grenoble 17

3. Technology transfer • PLATINE on PLUME-Feather (RELIER project) http://projet-plume.org/en/relier/platine-0 http://projet-plume.org/relier/platine November 17 2009 FOSSa - Grenoble 18

4. Learned lessons • Unfortunate aspects – Not enough time and human ressources at LAAS to complete our platform – No community created – Not enough time to support external projects • Tokushima University (Japan): cooperation with a phd student (2004-2006) • Lakehead University (Canada): cooperation with a teacher after the ED-MEDIA Conference 2005 (2005-2006) November 17 2009 FOSSa - Grenoble 19

4. Learned lessons • Nice surprises – A very good entry point for new research projects: • 2002-2005: IST Lab@Future using all PLATINE components + automatic deployment with JavaWebStart • 2006-2008: IST Sat6 using JVisioConference + SIP • 2004-2008: IST EuQoS using JVisioConference + QoS • 2007-2010: ITEA UseNET using Jchat + automatic deployment for mobile phones (J2ME, OSGi, Android, …..) – Always available, interesting for a lot of people: • 892 reads of French RELIER card since 09 2008, • 299 reads of English card since 04 2009 November 17 2009 FOSSa - Grenoble 20

5. Conclusion • PLATINE : an enriching experience from both technical and human point of view • A nice way to introduce me in RELIER project November 17 2009 FOSSa - Grenoble 21

Tokushima University (Japan) 2004 Questions ? LIRM Tokyo – Toulouse – 05 2005 Tokushima - 2006 Santa-Catarina University Brasil – Toulouse 06-2005 November 17 2009 FOSSa - Grenoble 22
