The VBD is a 1D laterotactile display composed of 12 stacked piezoelectric bending sheets. The amount of bending of each piezo-sheet is controlled independently of the others. The display can be mounted on a linear slider whose position is monitored by an encoder.
This movie shows a sinusoidal wave traveling over the display. See the virtual Braille dots project page for more movies of the VBD.
