USER INTERFACE DEVICE CAPABLE OF IMAGE SCROLLING NOT ACCOMPANYING FINGER MOVEMENT, IMAGE SCROLLING METHOD, AND PROGRAM
First Claim
1. A user interface device operable to perform a display function of displaying an image, a touch panel function of outputting successive locations of the user'"'"'s finger contact point on a touch screen over time, and a function of scrolling an integral image being displayed, in response to a drag motion performed on the touch screen with the user'"'"'s finger, the user interface device comprising:
- a pressing-force sensor detecting a pressing force with which the finger presses the touch screen;
a motion-recognizing unit configured to determine whether or not the drag motion has ended;
a scroll-rate determining unit configured to be operable in response to the motion-recognizing unit determining that the drag motion has ended, to determine a post-drag scroll rate that is a scroll rate of scrolling to be performed subsequently to the drag motion, based on a magnitude of the pressing force detected by the pressing-force sensor at an end time of the drag motion and/or during a period of time after the end time of the drag motion; and
a scroll controller configured to further scroll the integral image being displayed, at the determined post-drag scroll rate, after scrolling invoked by the drag motion ends.

Abstract
A process is disclosed of scrolling an image on a user interface device configured to display the image on a display screen and enable a user to input with the user'"'"'s finger touch on a touch screen in association with the displayed image, the process including: scrolling the image in response to the finger'"'"'s drag motion on the touch screen; and, in response to an event occurring in which, after the drag motion ended, the finger is held in touch with the touch screen at substantially the same location as where the finger was located when the drag motion ended, without releasing from the touch screen, further scrolling the image to perform follow-up scrolling, after experiencing an idle period or not.

11. A method of scrolling an image on a user interface device operable to perform a display function of displaying an image, a touch panel function of outputting successive locations of the user'"'"'s finger contact point on a touch screen over time, and a function of scrolling an integral image being displayed, in response to a drag motion performed on the touch screen with the user'"'"'s finger,
wherein the user interface device comprises a pressing-force sensor detecting a pressing force with which the finger presses the touch screen, the method comprising: -
a first step of determining whether or not the drag motion has ended; a second step of determining, in response to the motion-recognizing unit determining that the drag motion has ended, a post-drag scroll rate that is a scroll rate of scrolling to be performed subsequently to the drag motion, based on a magnitude of the pressing force detected by the pressing-force sensor at an end time of the drag motion and/or during a period of time subsequent to the end time of the drag motion; and a third step of further scrolling the integral image being displayed, at the determined post-drag scroll rate, after scrolling invoked by the drag motion ends. - View Dependent Claims (12, 16)

13. A process of scrolling an image on a user interface device configured to display the image on a display screen and enable a user to input with the user'"'"'s finger touch on a touch screen in association with the displayed image, the process comprising:
-
a first step of scrolling the image in response to the finger'"'"'s drag motion on the touch screen; and a second step of further scrolling, in response to an event occurring in which, after the drag motion ended, the finger is held in touch with the touch screen at substantially the same location as where the finger was located when the drag motion ended, without releasing from the touch screen, the image to perform follow-up scrolling, after experiencing an idle period or not. - View Dependent Claims (14, 15)
