Method and system for selecting objects on a tablet display using a pen-like interface
First Claim
1. A system for selecting objects on a screen comprising:
- a display means for displaying objects on a screen,a substantially pen-shaped pointing means for pointing to a position on a screen,a detection means for detecting both the plane position of the point of said pointing means and the distance between the point of said pointing means and the screen of said display means, anda control means for displaying a plurality of objects on the screen of said display means, said control means displaying objects in an enlarged form on said screen in a predetermined enlarged image area containing the predetermined position on the screen corresponding to said plane position when the distance detected by said detection means is less than or equal to a first predetermined value and greater than a second predetermined value, said second value being smaller than said first predetermined value, said control means fixing the enlarged objects displayed in said enlarged image area regardless of the change in plane position detected by said detection means when said distance detected by said detection means is less than or equal to said second predetermined value, and said control means selecting the object at the position on said screen pointed to by said pointing means when a selecting action is taken.

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.

9. A method for selecting objects on a screen, said method comprising the steps of:
-
displaying objects on a screen of a display means; displaying a preselected number of the objects in an enlarged form in a predetermined enlarged image area containing the position on the screen corresponding to the plane position of the point of a substantially pen-shaped pointing means when the distance between the point of said pointing means and the screen of said display means is equal to or smaller than a first predetermined value and greater than a second predetermined value which is smaller than said first predetermined value; fixing the state where the objects displayed in said enlarged image area are displayed in an enlarged form regardless of the change of the plane position of the point of said pointing means when said distance is less than or equal to said second predetermined value; and selecting the object displayed at the position pointed to by said pointing means. - View Dependent Claims (10, 11, 12)
