[Embodiment 1]
FIG. 1 is an explanatory diagram illustrating an outline of the operation of the information processing apparatus 10. The information processing device 10 of the present embodiment is an information device such as a tablet-type electronic book reader provided with a display unit 20, a general-purpose tablet, a smartphone, or a personal computer. The case where the information processing apparatus 10 is a tablet-type electronic book reader will be described as an example.

A schematic diagram of the document file 31 of the electronic book is shown in the center of FIG. The contents of the document file 31 are described from the upper side to the lower side of the schematic diagram. A schematic diagram of the information processing apparatus 10 is shown on the left and right of FIG. The display unit 20 can display a part of the document file 31.

The white circle shown in the display unit 20 of FIG. 1 indicates a state in which the characters in the document file 31 are stopped or slowly scrolled. The upward arrow shown in the two display units 20 in the center in the vertical direction of FIG. 1 indicates a state in which the document file 31 is scrolled upward at high speed.

The left side of FIG. 1 shows an example of an operation and display when the user first reads the document file 31. The user operates the touch panel provided on the surface of the display unit 20 to select the document file 31 to be viewed. When the information processing apparatus 10 is activated, the document file 31 whose browsing was interrupted last time by the user may be automatically selected.

A document file 31 (see FIG. 2) recording the selected document is obtained from the auxiliary storage device 14 (see FIG. 2). A part of the document file, for example, a part at the beginning or a part where the user interrupted the previous browsing is displayed on the display unit 20.

The user operates the touch panel provided on the surface of the display unit 20 to scroll the document file 31. The user slowly reads the first area 311 indicated by the hatch in the document file 31. After that, the user scrolls the second area 312 shown in white at high speed and skips it. The user slowly reads the third area 313 indicated by hatching in the document file 31.

The slowly read line is displayed on the display unit 20 for a long time. The lines scrolled at high speed are displayed on the display unit 20 for a short time. In the deceleration DB 33, which will be described later, the time when each line of the document file 31 is displayed on the display unit 20 is recorded.

The right side of FIG. 1 shows an example of a display when the user reads the document file 31 for the second time. The information processing device 10 of the present embodiment has an automatic scrolling function that continues scrolling even when the user releases the touch panel.

Even when the user operates to automatically scroll at high speed, the first area 311 and the third area 313, which are recorded to have been displayed in the deceleration DB 33 for a long time, are slowly scrolled. The second area 312 in which it is recorded that the deceleration DB 33 has been displayed for a short time is scrolled at high speed as specified by the automatic scroll operation.

Even during automatic scrolling, the user can perform operations such as stopping, decelerating, or reversing scrolling by operating the touch panel. Even when the user reads the document file 31 for the second time, the time when each line of the document file 31 is displayed on the display unit 20 is recorded in the deceleration DB 33, and is reflected in the subsequent determination of the presence or absence of deceleration.

When reading a paper book, the user holds the book in his hand, flips through it, and opens the required page to read it. In particular, a user who rereads a book once read can quickly open and read an important part based on the traces such as page opening habits left unknowingly when reading the same book in the past.

According to the information processing apparatus 10 of the present embodiment, even when scrolling at high speed, the scroll speed becomes slow at a place where the user has spent a lot of time reading in the past. Therefore, the user can easily find the part that he / she felt was important in the past and took time to read it. Therefore, it is possible to provide an information processing device 10 capable of allowing a user to read an electronic book with the same feeling as when flipping a paper book.

FIG. 2 is an explanatory diagram showing the configuration of the information processing apparatus 10. The information processing device 10 includes a CPU (Central Processing Unit) 12, a main storage device 13, an auxiliary storage device 14, a communication unit 15, an input unit 17, a display unit 20, and a bus.

The CPU 12 is an arithmetic control device that executes a program according to the present embodiment. As the CPU 12, one or a plurality of CPUs, a multi-core CPU, or the like is used. The CPU 12 is connected to each part of the hardware constituting the information processing apparatus 10 via a bus.

The main storage device 13 is a storage device such as a SRAM (Static Random Access Memory), a DRAM (Dynamic Random Access Memory), and a flash memory. The main storage device 13 temporarily stores information necessary in the middle of processing performed by the CPU 12 and a program being executed by the CPU 12.

The auxiliary storage device 14 is a storage device such as a SRAM, a flash memory, a hard disk, or a magnetic tape. The auxiliary storage device 14 stores a document file 31 such as an electronic book, a deceleration DB 33, a program to be executed by the CPU 12, and various information necessary for executing the program. The document file 31 may be a file other than an electronic book, such as an e-mail, an SNS (Social Networking Service) log, or various reports.

The document file 31 can use any format such as EPUB (Electronic Publication) format, HTML (Hyper Text Markup Language) format, PDF (Portable Document Format) format, plain text format, word processor file format, and the like. Is. In the present embodiment, a document file 31 capable of performing so-called reflow type display, in which character data is taken out and scrolled and displayed, is used.

The communication unit 15 is an interface for communicating with a network (not shown).

The display unit 20 is a display panel such as a liquid crystal display panel, an organic EL (Electro Luminescence) display panel, or electronic paper. The input unit 17 is a touch sensor arranged on the surface of the display unit 20. That is, the display unit 20 and the input unit 17 integrally form a so-called touch panel.

A goggle-type or eyeglass-type head-mounted display may be used for the display unit 20. In this case, it is desirable to use a so-called motion sensor that detects the movement of the user's hand and arm, a microphone that performs voice input, a line-of-sight input device that detects the user's line of sight, or the like for the input unit 17.

FIG. 3 is an explanatory diagram showing the record layout of the deceleration DB 33. The deceleration DB 33 is a DB that records the line number of the document file 31, the time when the line is displayed in the document area 59, and the deceleration flag in association with each other. The deceleration DB 33 may be stored in an external storage device connected to the information processing device 10. The deceleration DB 33 is an example of the first recording unit of the present embodiment.

The deceleration DB 33 has a document file field, a line field, a display time field, and a deceleration flag field. In the document file field, a name or ID (Identifier) that identifies the document file 31 is recorded. In the line field, the line number of the document stored in the document file 31 is recorded. In the display time field, the cumulative time when the line corresponding to the line number field is displayed in the document area 59 is recorded.

In the deceleration flag field, a flag for whether or not to decelerate the scroll speed is recorded when the row corresponding to the row number field is displayed on the display unit 20. When the deceleration flag is "OFF", the CPU 12 does not decelerate the scroll speed. When the deceleration flag is "ON", the CPU 12 decelerates the scroll speed.

The deceleration DB 33 has one record for one line number. The deceleration DB 33 may record the deceleration flag in any unit such as a character unit, a paragraph unit, or a page unit. In this case, the deceleration DB 33 has one record for each unit for recording the deceleration flag.

The CPU 12 records "ON" in the deceleration flag field of the record whose time recorded in the display time field is longer than the threshold value. Specifically, for example, the CPU 12 calculates the mean value μ and the standard deviation σ of the display time recorded in the display time field, and sets the mean value μ + coefficient A × standard deviation σ as the threshold value. When the time when each line is displayed in the document area 59 is normally distributed, by setting the coefficient A to 3, the CPU 12 sets the deceleration flag field of the line whose display time on the display unit 20 is about 0.3%. Record "ON".

The CPU 12 can set A to any number other than 3. When A is made smaller, the threshold value becomes smaller, and the number of lines in which "ON" is recorded in the deceleration flag field increases. When A is increased, the threshold value is increased, and the number of lines in which "ON" is recorded in the deceleration flag field is reduced.

The CPU 12 may set, for example, the required time of the rows from the longest display time recorded in the display time field to a predetermined order as the threshold value. The CPU 12 may accept the input of the threshold value by the user. In addition, the CPU 12 can set the threshold value by any method.

FIG. 4 is an explanatory diagram showing the appearance of the information processing apparatus 10. As described above, the information processing apparatus 10 includes a display unit 20. The CPU 12 displays a document area 59, an acceleration button 53, a deceleration button 54, a stop button 55, and a direction button 56 on the display unit 20. The CPU 12 scrolls and displays the document file 31 in the document area 59. The CPU 12 accepts the user's selection of the acceleration button 53, the deceleration button 54, the stop button 55, and the direction button 56 via the touch panel arranged on the surface of the display unit 20.

The type and arrangement of the buttons are examples, and may be changed according to the preference of the user of the information processing apparatus 10. In the present embodiment, the case where the CPU 12 horizontally displays the document file 31 in the document area 59 will be described as an example, but the CPU 12 may display the document file 31 vertically in the document area 59. In the case of vertical writing display, the CPU 12 scrolls and displays the document file 31 in the left-right direction.

When the selection of the acceleration button 53 is accepted, the CPU 12 increases the scroll speed. When the selection of the deceleration button 54 is accepted, the CPU 12 slows down the scroll speed. When the selection of the stop button 55 is accepted, the CPU 12 stops scrolling. When the selection of the stop button 55 is accepted again, the CPU 12 restarts scrolling. When the selection of the direction button 56 is accepted, the CPU 12 reverses the scroll direction.

Further, the CPU 12 accepts a user's operation via the document area 59. For example, when a flick operation of swiping a finger up or down on the document area 59 is accepted, the CPU 12 starts scrolling in the paid direction. When the flick operation in the same direction as the scrolling direction is already accepted, the CPU 12 increases the scroll speed.

When the touch operation of touching the document area 59 for a short time is accepted, the CPU 12 stops scrolling. When the operation of sliding the finger on the document area 59 is accepted, the characters displayed in the document area 59 are displayed so as to follow the finger.

With the user interface described above, the CPU 12 accepts a scroll operation by the user. The scroll speed determined by the CPU 12 based on the accepted operation is called a reference scroll speed.

In the present embodiment, the information processing apparatus 10 in which the CPU 12 keeps the reference scroll speed constant until the user receives an additional operation will be described as an example. The CPU 12 may automatically reduce the reference scroll speed when a predetermined time has elapsed from the operation by the user.

The CPU 12 may accept the setting of the initial value of the scroll speed via a menu screen (not shown) or the like. The initial value of the scroll speed is set by the publisher of the electronic book and may be distributed together with the document file 31.

FIG. 5 is an explanatory diagram illustrating the scroll speed. The upper part of FIG. 5 is a graph illustrating the change in scroll speed. The horizontal axis indicates the line displayed on the first line of the display unit 20. The vertical axis shows the scroll speed.

At the bottom of the graph, the values recorded in the deceleration flag field of the deceleration DB 33 are shown in association with the rows on the horizontal axis of the graph. "OFF" is recorded in the deceleration flag field of the record corresponding to the lines from the 0th line to the α1st line, the (α2 + 1) line to the α3rd line, and the lines after the (α4 + 1) line. "ON" is recorded in the deceleration flag field of the record corresponding to the line from the (α1 + 1) th line to the α2 line and the line from the (α3 + 1) line to the α4th line.

That is, the rows (α1 + 1) to α2 are in the first region 311 in FIG. 1, and the rows (α2 + 1) to α3 are in the second region 312 in FIG. 1, the row (α3 + 1). To α4 line correspond to the third region 313 in FIG. 1, respectively.

The graph shown in FIG. 5 shows the scroll speed at which the CPU 12 scrolls and displays the document file 31 on the display unit 20 when the reference scroll speed is a constant value V1. At the place where the deceleration flag is "OFF", the CPU 12 scrolls at the reference scroll speed V1. Where the deceleration flag is "ON", the CPU 12 scrolls and displays the document file 31 at a deceleration scroll speed V2 slower than the reference scroll speed V1.

At the α2nd line and the α4th line where the deceleration flag changes from “ON” to “OFF”, the CPU 12 returns the scroll speed from the deceleration scroll speed V2 to the reference scroll speed V1.

FIG. 6 is a flowchart showing the flow of processing of the program. The CPU 12 acquires the document file 31 from the auxiliary storage device 14 (step S501). The CPU 12 may acquire the document file 31 from an external large-capacity storage device connected to the information processing device 10. The CPU 12 may acquire the document file 31 from a server (not shown) via the communication unit 15 and store it in the auxiliary storage device 14 or the main storage device 13. The CPU 12 may sequentially acquire a part of the document file 31 by a streaming method and temporarily store it.

The CPU 12 displays a part of the document file 31 in the document area 59 (step S502). When the document file 31 is in a format premised on page display such as PDF format, the CPU 12 extracts characters from the document file 31 and displays them on the display unit 20. Since the method of extracting characters from the document file 31 has been conventionally performed, the description thereof will be omitted.

The CPU 12 acquires a character string for one line following the portion shown in the document area 59 from the document file 31 (step S503). The CPU 12 acquires the reference scroll speed based on the operation received from the user (step S504).

The CPU 12 refers to the deceleration DB 33 and determines whether or not a portion of the document file 31 in which the deceleration flag is “ON” is displayed in the document area 59 (step S505). When it is determined that the portion where the deceleration flag is "ON" is displayed (YES in step S505), the CPU 12 calculates the deceleration scroll speed (step S506).

The deceleration scroll speed is a speed obtained by multiplying the reference scroll speed acquired in step S504 by a positive number of 1 or less. The deceleration scroll speed may be a speed obtained by subtracting a predetermined value from the reference scroll speed acquired in step S504. When the reference scroll speed is slower than a predetermined speed, the deceleration scroll speed may be the same as the reference scroll speed.

The deceleration scroll speed may be an arbitrary constant. The CPU 12 may receive a method of calculating the deceleration scroll speed according to the user's preference in advance and store it in the main storage device 13 or the auxiliary storage device 14.

Two or more deceleration stages are recorded in the deceleration flag field, and the CPU 12 may calculate the deceleration scroll speed according to the deceleration stages. The deceleration step may be determined, for example, based on the time recorded in the display time field.

The CPU 12 scrolls the document area 59 by one line using the deceleration scroll speed calculated in step S506 (step S507). When it is determined that the part where the deceleration flag is "ON" is not displayed (NO in step S505), the CPU 12 scrolls the document area 59 by one line using the reference scroll speed acquired in step S504 (step S508). ).

After the end of step S507 or step S508, the CPU 12 adds the time that the line was displayed in the document area 59 to the display time field of the scrolled line (step S525). The CPU 12 determines whether or not to end the process (step S510).

If it is determined that the process does not end (NO in step S510), the CPU 12 returns to step S503. When it is determined to end (YES in step S510). The CPU 12 activates the subroutine of DB update-1 (step S527). The subroutine of DB update-1 is a subroutine for updating the deceleration DB 33 described with reference to FIG. The processing flow of the subroutine of DB update-1 will be described later. The CPU 12 then ends the process.

FIG. 7 is a flowchart showing the processing flow of the subroutine of DB update-1. The CPU 12 determines the threshold value based on the deceleration DB 33 described with reference to FIG. 3 (step S531).

An example of how to set the threshold value will be described. The CPU 12 calculates the mean value μ and the standard deviation σ of the time recorded in the display time field of the deceleration DB 33. The CPU 12 calculates an average value μ + a coefficient A × a standard deviation σ and sets it as a threshold value. A is an arbitrary coefficient. The CPU 12 may determine the value of A based on the input by the user.

Another example of how to set the threshold value will be described. The CPU 12 extracts rows in a predetermined order counting from the one with the longest time recorded in the display time field, and sets the time recorded in the display time field of the row as a threshold value. In addition, the CPU 12 can set the threshold value by any method.

The CPU 12 sets the counter I to the initial value 1 (step S532). The CPU 12 acquires the I-th record from the deceleration DB 33 (step S533). The CPU 12 determines whether or not the time recorded in the display time field of the record acquired in step S533 is larger than the threshold value calculated in step S531 (step S534).

When it is determined that the value is larger than the threshold value (YES in step S534), the CPU 12 records "ON" in the deceleration flag field of the record acquired in step S533 (step S535). When it is determined that the value is equal to or less than the threshold value (NO in step S534), the CPU 12 records "OFF" in the deceleration flag field of the record acquired in step S533 (step S536).

After the end of step S535 or step S536, the CPU 12 determines whether or not the processing of the deceleration DB 33 is completed (step S537). If it is determined that the process has not been completed (NO in step S537), the CPU 12 adds 1 to the counter I (step S538). The CPU 12 returns to step S533. If it is determined that the process has been completed (YES in step S537), the CPU 12 ends the process.

According to this embodiment, it is possible to provide an information processing device 10 or the like that automatically reduces the scroll speed at a position where the deceleration flag is set to "ON".

According to the present embodiment, it is possible to provide an information processing apparatus 10 that changes the scroll speed based on the length of time required when reading the same document file 31 in the past.

According to the present embodiment, it is possible to provide an information processing apparatus 10 or the like that automatically reduces the scroll speed at a place where a time is longer than a threshold value in the past.

The CPU 12 scrolls the document area 59 by one line using the deceleration scroll speed calculated in step S506 (step S507). When it is determined that the part where the deceleration flag is "ON" is not displayed (NO in step S505), the CPU 12 scrolls the document area 59 by one line using the reference scroll speed acquired in step S504 (step S508). ).

After the end of step S507 or step S508, the CPU 12 adds the time that the line was displayed in the document area 59 to the display time field of the scrolled line (step S525). The CPU 12 determines whether or not to end the process (step S510).

If it is determined that the process does not end (NO in step S510), the CPU 12 returns to step S503. When it is determined to end (YES in step S510), the CPU 12 activates the subroutine of DB update-1 (step S527). The subroutine of DB update-1 is the same subroutine as the subroutine described with reference to FIG. 7. The CPU 12 then ends the process.

After the keyword is scrolled out from the display unit 20, the CPU 12 returns the scroll speed to V0.

FIG. 22 is a flowchart showing a processing flow of the program of the sixth embodiment. Since the processing up to step S633 is the same as the processing of the flowchart of the fifth embodiment described with reference to FIG. 20, the description thereof will be omitted.

When it is determined that the keyword is not included (NO in step S631), the CPU 12 scrolls the document area 59 by one line using the reference scroll speed acquired in step S504 (step S636).

When it is determined that the keyword is displayed in the deceleration area 51 (YES in step S633), the CPU 12 calculates the deceleration scroll speed (step S634). The CPU 12 scrolls the document area 59 by one line using the deceleration scroll speed calculated in step S634 (step S635).

The CPU 12 may change the scroll speed in three or more steps.

[Embodiment 7]
The present embodiment relates to an information processing apparatus 10 that smoothly changes the scroll speed. The description of the parts common to the second embodiment will be omitted.

FIG. 23 is an explanatory diagram showing a record layout of the score DB. The score DB is a DB that records the line number of the document file 31 in association with the time when the line is displayed in the document area 59 and the score determined based on the case. The score DB is stored in the auxiliary storage device 14. The score DB may be stored in an external storage device connected to the information processing device 10.

The score DB has a document file field, a line field, a display time field, and a score field. In the document file field, a name or ID that identifies the document file 31 is recorded. In the line field, the line number of the document stored in the document file 31 is recorded.

In the display time field, the cumulative time when the line corresponding to the line number field is displayed in the document area 59 is recorded. In the score field, the score calculated based on the time recorded in the line number field is recorded. The score DB has one record for one line number.

For example, the CPU 12 can standardize the time recorded in the display time field by the equation (1) so that the maximum value becomes 100 points, and determine the score.
The score of the Nth line = the display time of the Nth line / the maximum value of the display time × 100 ‥‥‥ (1)

The CPU 12 can determine the score by any other method so that the shorter time recorded in the display time field is the lower score and the longer time is the higher score.

FIG. 24 is an explanatory diagram showing a record layout of the speed coefficient DB. The speed coefficient DB is a DB that records the score recorded in the score DB in association with the speed coefficient indicating the degree of deceleration of the scroll speed. Here, the speed coefficient is a coefficient for calculating the deceleration scroll speed by integrating with the reference scroll speed. When the speed coefficient is 1, the deceleration scroll speed is equal to the reference scroll speed.

The speed coefficient DB is stored in the auxiliary storage device 14. The speed coefficient DB may be stored in an external storage device connected to the information processing device 10.

The velocity coefficient DB has a score field and a velocity coefficient field. The score is recorded in the score field. In the speed coefficient field, a speed coefficient indicating the degree of deceleration of the scroll speed is recorded. The speed coefficient DB has one record for one score.

25 to 27 are graphs illustrating an example of the speed coefficient DB. 25 to 27 show the points on the horizontal axis and the speed coefficient on the vertical axis. 25 to 27 show an example in which the CPU 12 determines a score between 0 and 100 points based on the equation (1).

FIG. 25 shows an example in which the relationship between the score and the rate coefficient is a linear function. When the score is the minimum value 0, the velocity coefficient is the maximum value 1. When the score is the maximum value 100, the velocity coefficient is the minimum value k.

When the score and the speed coefficient have the relationship shown in FIG. 26, the CPU 12 decreases the scroll speed as the score increases.

FIG. 26 shows an example in which the relationship between the score and the rate coefficient is a linear function when the score is P1 or higher. When the score is from 0 to P1, the velocity coefficient has a maximum value of 1. While the score is from P1 to 100, the relationship between the score and the rate constant is a linear function. When the score is the maximum value 100, the velocity coefficient is the minimum value k.

When the score and the speed coefficient have the relationship shown in FIG. 26, the scroll speed is the reference scroll speed for the scores from 0 to P1. When the score exceeds P1, the CPU 12 reduces the scroll speed to (reference scroll speed × speed coefficient).

FIG. 27 shows an example of a monotonic decrease function in which the relationship between the score and the rate coefficient is smooth. The velocity coefficient is 1 while the score is from 0 to P2. The velocity coefficient is the minimum value k while the score is from P3 to 100. While the score is from P2 to P3, the relationship between the score and the rate coefficient is a smooth curve.

When the score and the speed coefficient have the relationship shown in FIG. 27, the scroll speed is the reference scroll speed for the scores from 0 to P2. While the score is between P2 and P3, the CPU 12 reduces the scroll speed to (reference scroll speed × speed coefficient). That is, the scroll speed gradually slows down as the score increases. When the score exceeds P3, the velocity coefficient is the minimum value k. In this case, the scroll speed is the lowest speed.

Any other function can be used for the relationship between the score and the rate constant. For example, the relationship between the score and the speed coefficient may be changed depending on the reference scroll speed.

FIG. 28 is a flowchart showing a processing flow of the program of the seventh embodiment. The CPU 12 acquires the document file 31 from the auxiliary storage device 14 (step S501). The CPU 12 displays the document file 31 in the document area 59 (step S502).

The CPU 12 acquires a character string for one line following the portion shown in the document area 59 from the document file 31 (step S503). The CPU 12 acquires the reference scroll speed based on the operation received from the user (step S504).

The CPU 12 calculates the average score of the lines displayed in the document area 59 in the document file 31 with reference to the score DB described with reference to FIG. 23 (step S661). The CPU 12 refers to the coefficient DB described with reference to FIG. 24, and extracts the speed coefficient corresponding to the average point calculated in step S661 (step S662).

The CPU 12 calculates the scroll speed by multiplying the reference scroll speed acquired in step S504 by the speed coefficient extracted in step S662 (step S663). The CPU 12 scrolls by one line at the scroll speed calculated in step S663 (step S664).

The CPU 12 adds the time during which the line was displayed in the document area 59 to the display time field of the scrolled line (step S665). The CPU 12 determines whether or not to end the process (step S666).

If it is determined that the process does not end (NO in step S666), the CPU 12 returns to step S503. When it is determined to end (YES in step S666), the CPU 12 activates the subroutine of DB update-4 (step S667). The subroutine of DB update-4 is a subroutine for updating the score DB described with reference to FIG. 23. The processing flow of the subroutine of DB update-4 will be described later. The CPU 12 then ends the process.

FIG. 29 is a flowchart showing the processing flow of the subroutine of DB update-4. The CPU 12 searches the display time field of the score DB described with reference to FIG. 23 and extracts the maximum value (step S681). The CPU 12 sets the counter I to the initial value 1 (step S682).

The CPU 12 extracts the I-th record from the score DB (step S683). The CPU 12 calculates the score based on, for example, the equation (1) (step S684). The CPU 12 determines whether or not the processing of the deceleration DB 33 is completed (step S685).

If it is determined that the process has not been completed (NO in step S685), the CPU 12 adds 1 to the counter I (step S686). The CPU 12 returns to step S683. If it is determined that the process has been completed (YES in step S685), the CPU 12 ends the process.

In order to read a character that scrolls at high speed on the screen, the user needs to make the eyeball follow and move in conjunction with the scrolling character. Although there are individual differences, it is said that it is difficult for the user to read the characters being scrolled when the scroll angular velocity of the electronic book based on the user's eye, that is, the viewing angular velocity exceeds 10 degrees per second. .. Further, when the viewing angular velocity exceeds 15 degrees per second, it is almost impossible for the user's eyeball to follow the scrolling screen, and it is said that the scrolling screen cannot be visually recognized.

The distance suitable for reading is said to be about 30 cm to 45 cm. For example, if the distance between the information processing device 10 and the user's eyeball is 30 centimeters, the viewing angular velocity of 10 degrees per second corresponds to about 5 centimeters per second, and the viewing angular velocity of 15 degrees per second is about 8 centimeters per second. Equivalent to a meter. The upper limit scroll speed at which the user can read characters, that is, the scroll speed of 5 centimeters per second is defined as the readable speed Ve. The CPU 12 receives the designation of the readable speed Ve from the user and stores it in the main storage device 13 or the auxiliary storage device 14.

When using easy-to-read characters such as large fonts, and in the case of e-books that mainly contain pictures and contain almost no characters, the limit of the eyeball's follow-up movement is 15 degrees per second, that is, 8 cm per second. A scroll speed corresponding to meters may be used for the readable speed Ve. When using a small font, or in the case of a foreign language electronic book or the like, a scroll speed corresponding to 10 degrees per second, that is, 5 centimeters per second may be used for the readable speed Ve.

FIG. 30 is an explanatory diagram showing a record layout of the limiter DB. The limiter DB is a DB that records the line number of the document file 31 in association with the limiter flag indicating whether or not there is a speed limit at the time of scrolling. The limiter DB is stored in the auxiliary storage device 14. The limiter DB may be stored in an external storage device connected to the information processing device 10.

The limiter DB has a document file field, a line field, and a limiter flag field. In the document file field, a name or ID that identifies the document file 31 is recorded. In the line field, the line number of the document stored in the document file 31 is recorded.

In the limiter flag field, a flag is recorded as to whether or not to limit the scroll speed when the line corresponding to the line number field is displayed in the document area 59. When the limiter flag is "OFF", the CPU 12 does not limit the scroll speed. When the limiter flag is "ON", the CPU 12 limits the scroll speed to the readable speed Ve or less.

The limiter DB has one record for one line number. The limiter DB may record the limiter flag in any unit such as a character unit, a paragraph unit, or a page unit. In this case, the limiter DB has one record for each unit for recording the deceleration flag.

31 to 34 are explanatory views illustrating an outline of the operation of the information processing apparatus 10 according to the eighth embodiment. The central portion of FIGS. 31 to 34 is a graph showing the change in scroll speed. The horizontal axis indicates the line displayed on the first line of the display unit 20. The vertical axis shows the scroll speed.

FIG. 31 shows a record of the first reading state. The user of the information processing apparatus 10 scrolls the document file 31 at a high speed at a speed exceeding the readable speed Ve until the line S is displayed on the first line of the display unit 20. The upper diagram of FIG. 31 shows a situation in which the upward scrolling speed is too fast for the user to read individual characters.

After the line S is displayed on the first line, the user reads the document file 31 while appropriately changing the scroll speed. The user sets the marking 32 on the row V while reading. As shown in the lower right of FIG. 31, when the row T is displayed in the first row of the display unit 20, the row V is displayed in the bottom row of the display unit 20. Therefore, the row V is displayed on the display unit 20 while the horizontal axis of the graph is from the row T to the row V. The CPU 12 sets the deceleration flag corresponding to the line in which the marking 32 of the deceleration DB 33 is set to "ON". The detailed procedure for setting the marking 32 and the deceleration flag will be omitted.

FIG. 32 shows a record of the second reading state. The user of the information processing apparatus 10 reads the document file 31 at a speed lower than the readable speed Ve until the line N is displayed on the first line of the display unit 20. After that, the user scrolls the document file 31 at a high speed at a speed exceeding the readable speed Ve until the line Q is displayed on the first line of the display unit 20.

The user reads the document file 31 at a speed less than the readable speed Ve from the time when the line Q is displayed on the first line of the display unit 20 until the line R is displayed on the first line of the display unit 20. After that, the user inputs an instruction to the information processing apparatus 10 to scroll the document file 31 at a high speed exceeding the readable speed Ve.

The CPU 12 reduces the scroll speed to the readable speed Ve and displays the lines S and subsequent lines read by the user at a speed lower than the readable speed Ve last time. The user can read the important part that was read slowly last time without performing any special operation.

FIG. 33 shows a record of the third reading state. The user of the information processing apparatus 10 inputs to the information processing apparatus 10 an instruction to perform high-speed scrolling at a reference reference scroll speed exceeding the readable speed Ve. The CPU 12 reduces the scroll speed to the readable speed Ve and displays the scroll speed up to the row N and from the row Q to the row R that the user previously read at a speed less than the readable speed Ve.

Further, the CPU 12 reduces the scroll speed to the readable speed Ve and displays the line V in which the marking 32 is set even during the period when the line V is displayed on the display unit 20.

As described above, the CPU 12 automatically reduces the scroll speed to the readable speed Ve at the portion displayed by the user at a speed lower than the readable speed Ve and the portion where the marking 32 is set. To display.

FIG. 34 shows an example in the same situation as in FIG. 33, when the reference scroll speed input by the user is lower than that in FIG. 33. The CPU 12 reduces the scroll speed to the readable speed Ve and displays the scroll speed up to the row N and from the row Q to the row R that the user previously read at a speed less than the readable speed Ve.

Further, the CPU 12 scrolls and displays at a deceleration scroll speed determined based on the reference scroll speed during the period in which the row V in which the marking 32 is set is displayed on the display unit 20, for example, as in the first to seventh embodiments. do. When the deceleration scroll speed determined based on the reference scroll speed is faster than the readable speed Ve, the CPU 12 scrolls and displays at the readable speed Ve.

FIG. 35 is a flowchart showing the processing flow of the program of the eighth embodiment. The CPU 12 acquires the document file 31 from the auxiliary storage device 14 (step S501). The CPU 12 displays the document file 31 in the document area 59 (step S502).

The CPU 12 acquires a character string for one line following the portion shown in the document area 59 from the document file 31 (step S503). The CPU 12 acquires the reference scroll speed based on the operation received from the user (step S504).

The CPU 12 determines whether or not the reference scroll speed is less than the readable speed Ve (step S701). When it is determined that the speed is lower than the readable speed (YES in step S701), the CPU 12 refers to the deceleration DB 33 and displays in the document area 59 whether or not the deceleration flag in the document file 31 is "ON". Is determined (step S505). When it is determined that the part where the deceleration flag is "ON" is displayed (YES in step S505), the CPU 12 calculates the deceleration scroll speed (step S506).

The CPU 12 scrolls the document area 59 by one line using the deceleration scroll speed calculated in step S506 (step S507). When it is determined that the part where the deceleration flag is "ON" is not displayed (NO in step S505), the CPU 12 scrolls the document area 59 by one line using the reference scroll speed acquired in step S504 (step S508). ).

After the end of step S507 or step S508, the CPU 12 records "ON" in the limit flag field corresponding to the scrolled-out line of the limit DB (step S703).

When it is determined that the reference scroll speed is equal to or higher than the readable speed Ve (NO in step S701), the CPU 12 activates the speed limit scroll subroutine (step S705). The speed-limited scroll subroutine is a subroutine that scrolls at a scroll speed equal to or lower than the readable speed Ve in a predetermined case. The processing flow of the speed limit scroll subroutine will be described later.

After the end of step S703 or step S705, the CPU 12 determines whether or not to end the process (step S706).

If it is determined that the process does not end (NO in step S706), the CPU 12 returns to step S503. If it is determined to end (YES in step S706), the CPU 12 ends the process.

FIG. 36 is a flowchart showing the processing flow of the speed limit scroll subroutine. The CPU 12 refers to the deceleration DB 33 and determines whether or not a portion of the document file 31 in which the deceleration flag is “ON” is displayed in the document area 59 (step S721). When it is determined that the part where the deceleration flag is "ON" is displayed (YES in step S721), the CPU 12 calculates the deceleration scroll speed (step S722).

The CPU 12 determines whether or not the deceleration scroll speed is less than the readable speed Ve (step S723). If it is determined that the speed is less than the readable speed (YES in step S723), the CPU 12 scrolls the document area 59 by one line using the deceleration scroll speed calculated in step S722 (step S724). When it is determined that the speed is equal to or higher than the readable speed Ve (NO in step S723), the CPU 12 scrolls one line at the readable speed Ve (step S725).

When it is determined that the part where the deceleration flag is "ON" is not displayed (NO in step S721), the CPU 12 refers to the limiter DB and the limiter corresponding to the line displayed on the first line of the display unit 20. It is determined whether or not "ON" is recorded in the flag field (step S726).

When it is determined that ON is recorded (YES in step S726), the CPU 12 scrolls one line at the readable speed Ve (step S727). When it is determined that ON is not recorded (NO in step S726), the CPU 12 scrolls one line at the reference scroll speed (step S728).

After the end of step S724, step S725, step S727 or step S728, the CPU 12 records "OFF" in the limiter flag field corresponding to the scrolled-out line of the limiter DB (step S729). After that, the CPU 12 ends the process.

According to the present embodiment, the scroll speed is automatically reduced to the readable speed Ve and displayed at the place where the user previously displayed at a speed lower than the readable speed Ve and the place where the deceleration flag is set. It is possible to provide the information processing apparatus 10.

The part intentionally displayed by the user at a speed lower than the readable speed Ve and the part where the deceleration flag is set are likely to be important to the user and have high reading value. Such a location can provide an information processing device 10 that assists the user in preventing over-reading by reducing the scroll speed to the readable speed Ve or less.

On the other hand, there is a high possibility that the part where the user does not intentionally reduce the scroll speed while scrolling at the readable speed Ve is a part where the user's interest has already diminished. It is possible to provide the information processing apparatus 10 that does not make the user feel annoyed by displaying such a portion at the reference scroll speed without lowering the scroll speed thereafter.

The information processing device 10 may include a distance sensor that measures the distance between the display unit 20 and the user's eyes. The CPU 12 can calculate the readable speed Ve based on the measured distance.
