The first prototype of the BlindPAD as a full portable device is ready and tested at FIRR in Poland and Chiossone in Italy. In the video Prof. Herbert Shea from EPFL explains the BlindPAD.
The innovative 12×16 haptic device in action.
Luca Brayda and Fabrizio Leo explain what are the implications of delivering graphical concepts through touch to blind persons.
Haptic display from the BlindPAD consortium with 16 independent taxels (touchable pixels), to demonstrate EPFL’s electromagnetic actuation technology to provide graphical information to blind and visually impaired users.
We use an array of microfabricated coils to generate localized magnetic fields to move miniature magnets up and down. The magnets displace 3D printed taxels, which is what the user touches. This approach gives us large vertical displacement (over 0.5 mm) coupled with good holding force (25 mN) and a refresh time of under 1 second for the entire array.
In this video a journalist interviewed Fabrizio Leo (IIT) about the disseminated scientific content of the BLINDPAD project.
