1. An apparatus including a display section with a touch screen, the touch screen being adapted to display at least one graphical user interface object and detect a touch position on the touch screen, the touch position being inputted with a user'"'"'s finger or a pointing device, the apparatus comprising:

  • a haptic feedback generating unit attached to the touch screen and adapted to generating haptic feedback;

    a pressure sensing unit attached to the touch screen and adapted to detect pressure applied to the touch screen; and

    a controller section adapted to control and drive the display section;

    whereinthe graphical user interface object displayed on the touch screen has a plurality of logical states;

    the controller section determines a current logical state of the graphical user interface object using a history of detected touch positions and a history of detected pressure values;

    the controller section further determines a form of the haptic feedback to be generated depending on (i) the detected touch position, (ii) the detected pressure value and (iii) the determined current logical state of the graphical user interface object.
