This paper presents a novel approach on guiding people how to interact with touch screen based public displays. In our approach, we apply an additional layer of transparent plastic employing different shapes of laser cut holes that is placed on top of the public display. The holes restrict the touch screen input area, and provide a physical guidance to the user on interactive elements on the screen. This enables interaction styles with the screen that are not practical in the unguided case. Moreover, the guiding plastic layer can easily be replaced with another one with altering pattern. This provides opportunities to apply different interaction templates e.g. according to the display's location or users.
