Haptic feedback touchscreen

Consortium parner Linz Center of Mechatronics GmbH (LCM) developed an innovative touch screen with haptic feedback features. The heart of the recently patented system is a transparent plate, which is actively deformed by piezoelectric actuators. The plate provides haptic feedback precisely at the moment it is touched, rather similar to the impression obtained by physically tapping a conventional key. Interaction with touch panels becomes more intuitive, and input accuracy increases. More can be found in attached PDF.

More details on haptic-feedback can be also found on dedicated LCM webpage (EN).

The technology was recently pantented in Germany, as LCM press release says (DE).
