  • 1.
  • 2. Broadband Communications and Distributed Systems
    AXARMAn Extensible Remote Assistance and Monitoring Tool for Tele-rehabilitationJose L Marzo<joseluis.marzo@udg.edu>Barcelona, 4 June, 2010
  • 3. Outline
    Motivation
    Project description
    Design features
    Internal structure / Modularity
    Main features
    Future work
    Demo (Video clips)
  • 4. Motivation
    At the province of Girona three main aspects to develop the project can be highlighted:
    Geographical dispersion
    Difficult to reach adapted transport
    Patients’ handicaps
  • 5. Geographicaldispersion
  • 6. Difficult to reach adapted transport
  • 7. Patients’ handicaps
  • 8. Project description
    Video conference oriented and enhanced system which allows specialized professionals of a rehabilitation center (such as psychologists, neurologists and rehabilitators) to carry out distant rehabilitation sessions. Patients can remain at home using broadband communications and Internet services.
  • 9. Design objectives
    Area of influence: Girona province
    Geographical dispersion, budget limitations, patient exhaustion and discomfort
    Well developed Broadband access & 3G mobiles
    TRiEMapplication
    Use of standard available low-cost hardware
    Usual broadband connection: 1000/300 kbps
    On-line and off-line rehabilitation activities
  • 10. Mainbenefits
    Patient
    Better accessibility to treatment
    Cost and stress of transport reduction
    Continuous treatment
    Complications prevention
    Patient can easily keep their laboral and social activities
    • Rehabilitation center (RC)
    • 11. Better reenrollment ratio
    • 12. Audio-video recording facilities
    • 13. Virtual structure enlargement
    • 14. The RC can offer better and more advanced services
    • 15. Improvement in clinic records management
  • AXARM common hybrid P2P architecture
    Sessionmanagement, information and remote control messages
    Remote center orpatient’s home
    Doctor/specialist
    Audio, video, and real-time information
  • 16. Application architecture
    Hybrid P2P architecture
    Heterogeneous nature of broadband home connections
    Java + Java Media Framework JMF (cross-platform)
  • 17. The User Interface (configurable)
  • 18. AXARM is modular, multiplatformandsecure
    Modular
    • Based on a set ofplugins
    Multiplataform
    • AXARM doesnotdepend on a particular OperatingSystem
    Security/ Confidenciality
    • Atpatientlevel
    • 19. Atsystem (server) level
  • Implementation details (communications)
    Communication Technology: Jabber
    Decentralized
    Anyone can run their own Jabber server
    Open Standard
    Lightweight, human-readable and understandable messages
    No royalties required
    Security
    Server isolation and data encryption
    Flexibility
    Easy to extend via new message types
    Communication Library: Smack (JBother)
  • 20. Implementation (multimedia)
    RTP Protocol and Codecs
    H.263/RTP CIF video (352x288, 200 kbps)
    GSM/ULAW audio
    Java Media Framework (JMF)
    Capture, playback, streaming, and transcoding
    Isolates the application of OS interfaces
    Media4j
    Framework built on top of JMF
    Simplifies working with JMF
  • 21. User interface
    Contacts list
    • Roster
    • 22. Classical instantaneous messenger systems
    • 23. UI: Multimedia windows
    • 24. 3 permanent panels (docking windows)
    • 25. Remote Video, Local Video Local and Chat room
    • 26. Notes book, multimedia Library and file transfer
  • Currentdevelopment
    Re-factorization of the program (new code same functionalities)
    Easy activities extension (about 3 week cycle)
    Synchronous and Asynchronous activities (recording results)
    Asymmetric interface, doctor’s side is more powerful managing the applications
    Physicalactivities(dancingpad)
    Cognitiveactivities
  • 27. Comunicacions i Sistemes Distribuïts
    FUTUR INMEDIAT
    • Incorporació de maquinari adaptat
    • 28. Dispositius existents modificats
    • 29. Dispositius dissenyats específicament per l’aplicació
    • 30. Acceleròmetres i ultrasons per mesurar angles i distàncies
    • 31. Sensors de contacte i pressió
    • 32. Versió “caixa negra” del sistema
    • 33. Netbook o subnotebook (<400€) amb Linux adaptat a TRiEM
    • 34. Perfil d’usuari a un dispositiu físic (tarja de memòria o memòria USB)
  • Comunicacions i Sistemes Distribuïts
    Evolució de TRiEM
    Modularitat
    • Basat en programari lliure (control total de les funcionalitats)
    • 35. Ús i adaptació de dispositius de control de videojocs
    • 36. Per ara, joysticks i dancepads
    • 37. Properament, dispositius sense fils de la consola Wii
    • 38. Una extensió pot fer-se servir per més d’una activitat de telerehabilitació
    • 39. Variació de recorreguts a “Carretera”
    • 40. Seqüències a “Catifa de Ball”
    • 41. Noves funcionalitats
    • 42. Streamingd’audio/vídeo en diferit
  • New devices to be integrated
