First Claim
1. A user interface device for displaying on a display screen a zoom target, and for enabling a user to perform an input action by touching the display screen with a finger, the user interface device comprising:
- a pressing-force sensor detecting a pressing force with which the finger presses the display screen;
at least one of a virtual or physical reduction button and a virtual or physical undo button; and
a zoom controller configured to;
enlarge the zoom target in response to the detected pressing force exceeding a predetermined enlargement threshold, with an enlargement ratio of the zoom target depending on a magnitude of the pressing force, without requiring the user to operate an enlargement button,hold a size of the zoom target without restoring the size of the zoom target to an original size in response to a release of the finger from the display screen,wherein the reduction button is present, reduce the zoom target, in response to the user touching the reduction button, andwherein the undo button is present, restore the size of the zoom target so that the size becomes equal to the original size, in response to the user touching the undo button.
