ABSTRACT:
A method and system is provided wherein the information displayed in a predetermined area containing the predetermined position on the screen corresponding to the plane position of the point of a substantially pen-shaped pointing means is displayed in an enlarged form on said display means when the distance between the point of said pointing means and the screen of said display means is less than or equal to a first predetermined value and greater than a second predetermined value, where said second value is smaller than said first predetermined value. The state where the information which was displayed in said predetermined area is displayed in an enlarged form is maintained regardless of the change of the plane position of the point of said pointing means while said distance becomes said second predetermined value or smaller. The information which is displayed at a contact position or at a spaced position is selected when the point of said pointing means comes in contact with the screen or, alternatively, when the point is lifted from the screen after the point comes in contact with the screen.
