  The processing shown in FIGS. 2 and 3 is control by the control unit 20 until the operator drags the touch panel device 10 to draw a circle on the list and scrolls the list. .

  FIG. 4 is a diagram for explaining how the circle of the drag by the operator is determined.

  Here, the operation of the present embodiment will be described with reference to FIG. 2, FIG. 3, and FIG.

  In FIG. 2, initial processing is first performed in step S01. In FIG. 3, this initial process will be described.

  In step S001 in FIG. 3, it is determined whether three XY coordinates have been notified. If not notified, it enters a standby state until notified. When notified, in step S002, a right-angle line with respect to a straight line connecting the first notified XY coordinate and the second notified XY coordinate is obtained. In step S003, a right-angle line with respect to a straight line connecting the second notified XY coordinate and the third notified XY coordinate is obtained.

  Thereafter, in step S004, an angle that can be an intersection of the right-angle lines obtained in steps S002 and S003 is calculated. At this time, when the obtained angle is clockwise (downward angle shown in FIG. 4), it is set to plus, and when it is counterclockwise (upward angle shown in FIG. 4), it is set to minus.

  In step S005, the amount of movement during scrolling is calculated from the angle obtained in step S004. The amount of movement during scrolling is large when the angle is large, and small when the angle is small.

  In step S006, the time from the first XY coordinate until the third XY coordinate is notified is measured.

  In step S007, if the angle is a positive value, it is scrolled backward in step S008. At this time, the scroll amount calculated in step S005 is scrolled, and the scroll speed is adjusted from the time measured in step S006. If the angle is a negative value, scroll forward in step S008. At this time, the scroll amount calculated in step S005 is scrolled, and the scroll speed is adjusted from the time measured in step S006.

  The above is the flow of the initial process in step S01.

  Next, after the end of the initial processing in FIG. 3, it is determined in step S02 in FIG. 2 whether there is a newly notified XY coordinate. If not, the process ends. If there is, continue processing.

  In step S03, a right angle line is obtained with respect to a straight line connecting the last notified coordinate and the newly notified coordinate in step S02. In step S04, the angle obtained from the intersection of the right-angle line obtained last time and the right-angle line obtained in step S03 is calculated. At this time, when the obtained angle is clockwise (downward angle shown in FIG. 4), it is set to plus, and when it is counterclockwise (upward angle shown in FIG. 4), it is set to minus.

  In step S05, the amount of movement during scrolling is calculated from the angle obtained in step S04. The amount of movement during scrolling is large when the angle is large, and small when the angle is small.

  In step S06, the time from when the last notified coordinate is notified until the new coordinate is notified in step S02 is measured.

  In step S07, if the angle is a positive value, scroll backward in step S08. At this time, the scroll amount calculated in step S05 is scrolled, and the scroll speed is adjusted from the time measured in step S06. If the angle is a negative value, scroll forward in step S08. At this time, the scroll amount calculated in step S05 is scrolled, and the scroll speed is adjusted from the time measured in step S06.

  After scrolling in step S08 or step S09, the process returns to step S02, and it is further determined whether there are any newly notified coordinates. The above processing is repeated until coordinate notification is received.

  The above is the description of the operation control of the present embodiment.

  5, 6 and 7 show examples in which the list is scrolled by a drag operation for drawing a circle.

  FIG. 5 shows an example of drawing a small circle in the right direction (or left direction). If the currently displayed list is (1) to (5), the list is scrolled with a small scroll amount if the drag amount when drawing a circle in the right direction is small. For example, the list for one line is scrolled to display (2) to (6).

  FIG. 6 shows an example in which a small circle is drawn in the left direction (or right direction) as opposed to FIG. If the currently displayed list is (3) to (7), the list is scrolled with a small scroll amount if the drag amount when drawing a circle in the right direction is small. For example, the list for one line is scrolled to display (2) to (6).

  FIG. 7 shows an example when dragging is larger than in FIG. 5 or FIG. When the currently displayed list is (1) to (5), the scroll amount is increased when the drag amount when drawing a circle in the right direction is large (the circle is large). For example, the list for two lines is scrolled to display (3) to (7).

  In the present invention, if a drag operation for drawing a circle on the list is performed at any position on the screen, information desired to be browsed can be obtained without repeating the operation from touching the finger to releasing it. In addition, the scroll amount and scroll speed can be adjusted according to the size of the circle and the drawing speed.

  Further, the present invention provides a list of information to be viewed when browsing a screen that cannot be displayed unless the pages are switched, such as information that cannot be displayed on the screen (for example, a list) on the display of a terminal having a touch panel. A means that can be obtained by a single operation is provided. This means realizes scrolling of the list by performing a drag operation for drawing a circle with a finger (or a touch pen) on the touch panel.

  It is also possible to recognize that a circle has been drawn at any position on the screen.

  When it is recognized that a circle is drawn from the moving direction and moving amount based on the finger position information, the list is scrolled according to the size of the circle and the drawing speed. If you keep drawing a circle, you can keep scrolling. If the direction of drawing the circle is right (or left), you can switch to the next page for the displayed page, and if it is left (or right), the previous page for the displayed page You can switch to the page.
