6. DIVA Group – University of Fribourg traditional physical UI :: problems 1.electronics 2.missing API 3.unsuited API 4.commercial target 5.lack of simulation capabilities

7. DIVA Group – University of Fribourg 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.

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

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

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