  2. summary :: • traditional physical UI • examples • problems • phidgets • goals • definition • architecture • API • java API • programming • applications • references • bibliography • programming resources DIVA Group – University of Fribourg

  3. traditional physical UI ::examples Walking pad (DIUF) DIVA Group – University of Fribourg

  4. traditional physical UI ::examples Lego Mindstorms DIVA Group – University of Fribourg

  5. traditional physical UI ::examples SmartHome DIVA Group – University of Fribourg

  6. traditional physical UI ::problems • electronics • missing API • unsuited API • commercial target • lack of simulation capabilities DIVA Group – University of Fribourg

  7. phidgets ::goals • simple devices • easy to program … just as widgets make GUIs easy to develop, so could phidgets make the new generation of physical user interfaces easy to develop. DIVA Group – University of Fribourg

  8. phidgets ::definition • widget • (1931) small mechanical device • (today) ‘windows gadget’ • phidget (aka phydget) • ‘physical widget’ DIVA Group – University of Fribourg

  9. phidgets ::definition Phidgets™, or physical widgets, are building blocks that help a developer construct physical user interfaces. DIVA Group – University of Fribourg

  10. phidgets ::architecture Phidget DIVA Group – University of Fribourg

  11. phidgets ::architecture API Simulation Device Device manager DIVA Group – University of Fribourg

  12. phidgets ::API Phidget-specific properties, e.g. NumMotors Phidget-specific events, e.g. OnTag Specific phidget DeviceType IsAttached SerialNumber Generic phidget Int Count Phidget[] Item OnAttach() OnDetach() OnError() Phidgets manager DIVA Group – University of Fribourg

  13. phidgets ::java API DIVA Group – University of Fribourg

  14. phidgets ::java API DIVA Group – University of Fribourg

  15. phidgets ::programming (output) opens Phidget COM Object Device sets creates sets Application DIVA Group – University of Fribourg

  16. phidgets ::programming (input) opens Phidget COM Object Device starts creates fire events reads Listener Application DIVA Group – University of Fribourg

  17. phidgets ::programming Extend adapter Implement OnEvent methods Create COM Object Attach Listener Open connection to device Start listening DIVA Group – University of Fribourg
