Abstract
A touch screen 1111 having an active surface area 1112 which extends in three physical dimensions (x-, y- and z-dimensions) is provided. In the figure the active surface area has an U-shaped form. When a user slides his finger over the active surface area the tactile feedback gives him information about the position of the finger. The touch screen is activated when the active surface area senses a certain pressure from the finger. The use of the touch screen is facilitated especially when the user is on the move or when the touch screen is out of sight. Such use is common when operating hand-held terminals.
