1. A touch screen device comprising:
- a touch screen having one common active surface area which extends in three physical dimensions, said touch screen produces an output signal when said active surface area is activated by the positioning of an object at the surface of said active surface area, said output signal comprises information about the position of said object within said active surface area, said touch screen is characterized in that at least a part of said active surface area has a form in said three physical dimensions such that, when a user slides the object over the active surface area, the tactile feedback gives information to said user about the position of the object within said active surface area;
the touch screen including a ridge shaped screen portion; and
a pivot button for interaction between the tip of a finger of a user and said active surface area of said touch screen wherein the form of the pivot button is tied to the form of the active surface area of said touch screen such that the pivot button is slidable along said screen portion and is locked-on to the touch screen.

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.
