A method for providing a user graphical interface on a portable computerized control device (13) for industrial installations comprises the steps of providing on the touch screen (15) an image of an interface which comprises graphical control elements (20) which can be activated by the touch of the user and providing on the graphical screen in the vicinity of the lateral edge of the screen at least one icon (21) for enabling the interface. Such an icon is translatable between a rest position and an activation position by means of touch and dragging by the user on the touch screen and automatically returns from the enabling position into the rest position upon release of the touch thereon. In this way the interface is enabled for as long as the user keeps the enabling icon in the enabling position. |
