Abstract

PURPOSE:To recognize the weight of superposed cards and to realize scroll stop with natural feeling at the time of stopping scroll, by reducing the scroll speed of a picture gradually after touching off a finger. CONSTITUTION:At the time of retrieving a file 1, the content of the file 1 is displayed on a display part 3 with an image where the cards are superposed by a control part 2, and a finger input touch panel 4 is arranged at the front of the display part 3. And the pointing position coordinate and the pointing travel coordinate of the finger for the panel 4 are inputted to the control part 2, and at the control part 2, the card corresponding to the pointing position coordinate is scrolled following the pointing travel coordinate. In this case, the scroll speed of the picture displayed on the display part 3 is reduced gradually. In other words, since a way to stop the scroll after the touch off of the finger is performed in such way that the weight of a card image can be felt, it is possible to perform the scroll stop with the natural feeling.

Description

[Detailed Description of the Invention] [Summary] A file search device that searches for a file displayed on a display unit as an image of overlapping cards by scrolling the cards in accordance with the movement of a finger on a finger input touch panel. By gradually decreasing the scrolling speed and stopping the scrolling from the time you take your finger off the finger input touch panel after scrolling, we created a natural-looking stopping method that makes the weight of the overlapping cards confusing. It is something.

[Industrial application field]

The present invention relates to an improvement in a file search device that searches for a file displayed on a display unit as an image of overlapping cards by, for example, scrolling the cards in accordance with the movement of a finger on a finger input touch panel. Files such as telephone directories and employee lists are managed in card format, and the display section displays the cards in a superimposed image in a card arrangement that closely resembles the actual card arrangement.The card arrangement is then displayed on the finger input touch panel. There is a file search device that scrolls and displays cards in accordance with the movement of a finger and searches using an index or the like.

In this file search device, it is possible to stop the scrolling from the moment the scrolling of the cards is finished and the finger is removed from the finger input touch panel, but it is possible to stop the scrolling with a natural feeling in which the weight of the overlapping cards is confusing. desirable.

[Conventional technology]

This is a file search device that provides a natural operating feel by scrolling the cards by following the movement of the finger on the touch panel for finger input, while searching for files displayed on the display as an image of overlapping cards. There is a file search device for which the present applicant applied for a patent on December 2, 1986.

The contents of this will be explained below.

FIG. 4 is a block diagram of the main part of the file search device, FIG. 5 is a flowchart of a conventional program, and FIG. 6 is a display explanatory diagram of the conventional example.

In FIG. 4, 2 is a control unit, 10 is a processor, 11 is a RAM for storing files, etc., and 12 is a ROM for storing programs, etc., which also stores the programs shown in FIG. 13 is a display control unit, 3 is a display unit, and 4 is a finger input touch panel such as a transparent tablet, which is placed in front of the display unit 3. When you directly point at a display position with your finger, the coordinate information is displayed on the interface unit. 14 to the processor 10.

Using the program shown in FIG. 5, the processor 10 performs vertical scroll display control of the cards displayed on the display section 3 as an image of overlapping cards.

This vertical scroll display control will be explained below according to the program shown in FIG.

By touching the touch panel 4, the coordinates X, , Y at that time are determined in step 20 of FIG. Touch-on coordinates X+, Y input by and moved in step 21
When + is input, the movement amount d)F=
Y and -Y are calculated, and in step 23 scrolling is performed by dy.In step 24, it is checked whether touch-off has occurred, and if touch-off has occurred, scrolling is immediately stopped.

If there is no touch-off, in step 25 the coordinates X,
, Y, with coordinates X 0. As Y, repeat the same operation as above.

This scrolling operation is shown in Fig. 6.
In the figure, the touch input area that enables scrolling is set as shown by dotted lines.

In Figure 6 (A), touch on point A in the scrollable area, and move to the touched points A, B, C, and 2 as shown in (B), CC, and (D), and the card arrangement will change. The display moves following the movement coordinates, and scrolling stops when touched off.

[Problem that the invention seeks to solve]

However, the cards are displayed as overlapping images, and if the scrolling of the cards is stopped immediately upon touch-off, there is a problem that the weight of the overlapping cards will not be confused and the sense of naturalness will be lost.

[Means for solving problems]

As shown in the principle block diagram of the present invention in FIG.
A finger input touch panel 4 is disposed in front of the finger input touch panel 4, and the pointing position coordinates and pointing movement coordinates of the finger with respect to the finger input touch panel 4 are input to the control unit 2.
In the file search device that scrolls the card corresponding to the pointing position coordinates in accordance with the pointing movement coordinates, the scrolling speed of the screen displayed on the display section 3 is gradually decreased under the control of the control section 2. This problem is solved by the file search device of the present invention.

[Operation] According to the present invention, when you touch off your finger, the scrolling speed of the screen gradually decreases and then stops, so when you stop scrolling, you can feel the weight of the overlapping cards, creating a natural feeling. A certain stop is possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a flowchart of a program according to an embodiment of the present invention, and FIG. 3 is an explanatory diagram of a scroll display after the finger is released according to an embodiment of the present invention.

In the case of the present invention, the program shown in FIG. 2 is stored in the RO'M 12 in the control unit 2 of the file search device shown in FIG. 4, and after the finger touches off, the display is scrolled by this program. , then gradually reduce the scrolling speed and stop scrolling.

That is, in step 30 of FIG. 2, the y coordinate at touch-off is set to Y. Y- is the y-coordinate of the sampling point immediately before the sampling at touch-off.

In step 31, (y, −y −i /l
, (where 1. is the sampling period of the touch panel), and let this be the speed ■.

At step 32, the display screen is scrolled at this speed V.

Next, in step 33, scroll display is performed using the speed av obtained by multiplying V by a of Q<a<l. The scrolling continues exponentially (anv) until the speed v0, which takes seconds, is reached, and when the speed v0 is reached, the scrolling is stopped at step 34.

When this is shown on a display screen, it becomes as shown in FIGS. 3(A) and 3(B).

That is, after touch-off in Figure 6(D), the card is 3
The scrolling speed gradually decreases and the scrolling stops, as shown in FIG. 3(A), where the card is lowered by two cards, and then as shown in FIG. 3(B), where the card is lowered by two cards.

Note that this reduction in speed does not have to be exponential, but may be a method in which the speed is gradually reduced linearly.

〔Effect of the invention〕

As explained in detail above, according to the present invention, the weight of the overlapping card images becomes confusing when stopping scrolling after touching off the finger.
This has the effect of allowing you to stop scrolling with a natural feel.
