For multitouch and multiuser interactions on a touch surface, providing a local vibrotactile feedback is essential. Usually, vibration propagation impedes this localization. Previous work showed that narrow strip-shaped plates could allow the confinement of vibrotactile stimuli to the actuated area. Adding to this principle, periodically supported plates also provide a non-propagative effect at low frequencies. Using both geometrical properties, we provide a device allowing a multitouch
