*** Explanation of operation ***
Next, the display control method 510 of the display control apparatus 100 and the display control process S100 of the display control program 520 according to the present embodiment will be described with reference to FIG.
The display control process S100 according to the present embodiment includes a document display process S110 and a display change process S120.

<Document Display Processing S110>
First, document display processing S110 in which the display device 14 displays an electronic document will be described. In the document display process S110, the display device 14 receives a scroll instruction for instructing scrolling of the electronic document, and scrolls the electronic document based on the scroll instruction. The display device 14 receives a scroll instruction by a touch operation. When the display device 14 is not a touch screen display, a scroll instruction may be received by an input device other than the touch operation.

In step S101, the display device 14 determines whether or not there is a touch operation by the user. If there is a touch operation, the process proceeds to step S102. If there is no touch operation, the process proceeds to step S105.

In step S102, the touch data generation unit 201 converts a touch operation on the display device 14 by the user into touch data, and sends the touch data to the gesture recognition unit 202. Specifically, the touch data includes touch coordinates, a touch state indicating Up or Down, and a time stamp. The touch data is an example of a scroll instruction that instructs to scroll the electronic document.

In step S103, the gesture recognition unit 202 replaces the touch data acquired from the touch data generation unit 201 with a gesture.
In step S <b> 104, the gesture recognition unit 202 generates a gesture event for calculating the movement amount 203 of the electronic document corresponding to the gesture. That is, the gesture recognition unit 202 analyzes the touch data, converts the touch data into a gesture event, and sends the gesture event to the movement amount update unit 204. More specifically, the gesture recognition unit 202 calculates the speed from the touch coordinates and the time stamp of the previous touch data at the timing when the touch state Up is entered. The gesture recognition unit 202 determines that a flick has been input when the speed is equal to or greater than a threshold value. Then, the gesture recognition unit 202 refers to the touch area of the electronic document from the document data 207 and determines whether the flick is in the touch area. If the gesture recognition unit 202 determines that the flick is for an electronic document, the gesture recognition unit 202 sends a flick gesture event to the movement amount update unit 204. Note that the gesture recognition unit 202 may calculate the movement amount 203 of the electronic document from the flick gesture event and send the movement amount 203 to the movement amount update unit 204.

In step S105, the movement amount update unit 204 calculates the movement amount 203 of the electronic document in the next drawing from the gesture event, and updates the movement amount 203 of the storage unit 150. The processing of the movement amount update unit 204 is executed periodically, specifically for each drawing, and updates the movement amount 203 from the received gesture event. More specifically, when a flick gesture event is received, the movement amount update unit 204 calculates the movement amount 203 based on a simulation of an equation of motion having friction with the flick speed as an initial speed, and calculates the calculated movement amount. 203, the movement amount 203 of the storage unit 150 is updated.

In step S106, the position changing unit 205 calculates the display position of the electronic document in the next drawing from the movement amount 203 and the document data 207 stored in the storage unit 150. The position changing unit 205 refers to the display position of the current electronic document from the document data 207, and adds the movement amount 203 to the display position of the electronic document, thereby calculating the display position of the next electronic document to be displayed.

In step S107, the position changing unit 205 determines whether or not the display position of the electronic document calculated in step S106 exceeds the end of the electronic document. If so, the process proceeds to the display change process S120. If not, the process proceeds to step S108. The end of the electronic document is a position indicating an edge opposite to the direction in which the electronic document is scrolled. Specifically, when the electronic document is scrolled upward, it means the lower end of the electronic document. When the electronic document is scrolled downward, it means the upper end of the electronic document. Thus, the end of the electronic document is an edge portion that is finally displayed when the electronic document is scrolled.

If the display position of the electronic document does not exceed the end of the electronic document, the position changing unit 205 sets the display position according to the movement amount 203 and rewrites the document data 207 in step S108.
In step S109, the drawing unit 208 draws the document data 207 in the frame buffer 209.
In step S111, the display unit 210 of the display device 14 displays the frame buffer 209.
In step S112, the display unit 210 of the display device 14 determines whether or not the document display is finished. When it is finished, the operation is finished. If not completed, the process returns to step S101.

<Display change processing S120>
Next, when the vibration unit 206 as the display change unit 250 includes an instruction to scroll to the end of the electronic document, the electronic document is displayed without changing the display range of the electronic document displayed to the end by the display device 14. The display change process S120 for changing the display is executed. In the display change process S120, the vibration unit 206, which is the display change unit 250, changes the display of the electronic document so as to indicate that the end of the electronic document is displayed on the display device 14. At this time, the vibration unit 206 serving as the display change unit 250 may change the display of the electronic document in accordance with the movement amount 203 of the display position of the electronic document when the electronic document is scrolled.
The vibration unit 206 serving as the display changing unit 250 changes the display of the electronic document without changing the display range of the electronic document displayed to the end by the display device 14. The vibration unit 206 serving as the display change unit 250 displays at least a part of the electronic document displayed on the display device 14 so that the end of the electronic document is displayed on the display device 14. Represents that.

In step S121, the position changing unit 205 rewrites the document data 207 so that the display position of the electronic document ends. When the display position of the electronic document exceeds the end of the electronic document, the position changing unit 205 displays the electronic document so that the display position does not exceed the end. In addition, the position changing unit 205 sends the movement amount 203 to the vibration unit 206. Here, the range of the electronic document displayed so that the display position of the electronic document is at the end is set as the end display range 1411 (see FIG. 4 and the like). The end display range 1411 is an example of a display range of an electronic document displayed to the end by the display device 14.

In step S122, the vibration unit 206 rewrites the document data 207 so that the electronic document appears to vibrate. Specific examples of the vibration method of the electronic document are as follows.
As a first specific example, there is a method of moving the position of document data up and down, moving left and right, and moving it smoothly. Moreover, you may move by combining up and down, right and left, and licking. In other words, the display contents of the electronic document or the position of the display area is vibrated by a combination of up / down, left / right, and sleek movement.
The second specific example is a method of making document data appear to vibrate by being enlarged or reduced. That is, the display contents or display area of the electronic document is vibrated by enlarging, reducing, or a combination thereof.
The third specific example is a method of making the document data appear to vibrate by being deformed. That is, it is a method of vibrating the display contents or display area of the electronic document by deforming it.
The fourth specific example is a method of making text and image lines of document data appear to vibrate by making them thicker or thinner. That is, it is a method of vibrating the display contents or display area of the electronic document by deforming it.
As another specific example, there is a method of changing the font when the document data is text. Moreover, the method which combined said specific example may be sufficient. Any vibration method can be used as long as the electronic document displayed on the display device 14 can be recognized as vibrating. Further, the vibration width of the electronic document may be changed according to the movement amount 203 or may be constant. As for the vibration time, vibration may be continued until the movement amount 203 becomes 0, or a method of vibrating for a certain time from the start of vibration may be used.

As described above, even if the display of the electronic document is changed by vibration, the end display range 1411 of the electronic document displayed on the display device 14 is not changed.

In step S123, the drawing unit 208 draws the document data 207 in the frame buffer 209.
In step S124, the display unit 210 of the display device 14 displays the frame buffer 209.
The processes in steps S123 and S124 are the same as the processes in steps S109 and S111.
After step S124, the process proceeds to step S112.

This completes the description of the display control process S100 of the display control apparatus 100 according to the present embodiment.

Next, a user interface when the display control process S100 according to the present embodiment is executed will be described using a specific example. Here, description will be made assuming that the electronic document 141 is a list.

In FIG. 4, as a result of the gesture input 35 of FIG. 3, the list item 33 reaches the end, the end display range 1411 including the end of the list item 33 is displayed in the display area 142, and the list item 33 vibrates. It is a figure showing a mode. Here, only the list item 33 may be vibrated, or what is displayed in the display area 142 excluding the list item 33, specifically, the background or the like of the display area 142 may be vibrated or displayed. The region 142 itself may be vibrated or a combination thereof.

Next, with reference to FIGS. 5 and 6, when the display device 14 according to the present embodiment scrolls downward in a state where the end of the list that is the electronic document 141 is displayed, the end is displayed. A user interface for notifying will be described.
FIG. 5 is a diagram showing a state in which the list item 33 in the display area 142 of the display device 14 has reached the end, and the end display range 1411 including the end of the list item 33 is displayed. FIG. 6 is a diagram showing a state in which the list item 33 vibrates when the user tries to scroll the display device 14 by the gesture input 35 with the hand 34 in the state of FIG.
