(Embodiment)
FIG. 1 is a block diagram of an electronic book display device 1 according to the present embodiment.

  The electronic book display device 1 includes an electronic book storage unit 101, an operation detection unit 102, and a processing unit 103.

  The processing unit 103 includes page information acquisition means 1031, display means 1032, and power supply control means 1033.

  The electronic book display device 1 is a device for browsing electronic books. The electronic book display device 1 is realized by, for example, a so-called electronic book reader, a smartphone, a mobile phone, a mobile terminal, a computer, or the like. The electronic book display device 1 is preferably, for example, a portable device, and particularly preferably of a size that can be held with one hand.

  The electronic book storage unit 101 stores one or more pieces of electronic book information that is information on electronic books. An electronic book is a publication that can be read on a monitor screen of an electronic device. The electronic book is, for example, a book whose medium is an electronic medium. Electronic books are also called electronic books. For example, a WEB page or the like may be considered as an electronic book. For example, an electronic document generated by a so-called word processor, a text, a set of one or more images, and the like may be considered as an electronic book. The electronic book information is data of these electronic books, and the data format of the electronic book information is not limited. An electronic book has one or more pages. A cover or table of contents of an electronic book may be considered a page. The storage here is a concept including temporary storage. Information on one page of the electronic book is referred to as page information here. The electronic book storage unit 101 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The motion detection unit 102 detects the movement of the electronic book display device 1 in one or more directions specified in advance. The movement of the electronic book display device 1 may be considered as the movement of the housing of the electronic book display device 1. The motion detected by the motion detection unit 102 may be linear motion or rotational motion, and the motion does not matter. The one or more directions designated in advance may be a linear direction, or may be a rotation direction about one point or one axis. Moreover, these combinations may be sufficient. For example, the motion detection unit 102 detects a motion using motion information indicating a motion to be detected that is stored in advance in a storage unit (not shown). The motion information is information having a condition for detecting motion, for example. For example, the motion detection unit 102 detects a motion that satisfies the conditions of the motion information. The motion information includes, for example, information indicating the meaning of the motion and information indicating the motion condition. For example, the motion information includes information indicating the meaning of the motion “shake to the left” and information indicating the motion condition “the value of the x-axis vector is negative” and “the acceleration in the x-axis direction is equal to or greater than a threshold”. It is information to have. In this case, when detecting an x-axis vector having a negative value and detecting an acceleration equal to or greater than a predetermined threshold value in the x-axis direction, the motion detection unit 102 is designated in advance as “shake left”. This means that the movement is detected. Here, the x-axis vector is a vector indicating the motion in the x-axis direction.

  The motion detection unit 102 detects, for example, a motion of swinging the electronic book display device 1 left or right as a motion in one or more directions specified in advance. The movement swinging left or right may be considered as the movement swinging left or right. The shaking motion is, for example, a motion of moving the electronic book display device 1 at a speed or acceleration equal to or higher than a predetermined threshold value. Alternatively, a motion having a pre-designated feature amount may be detected as a shaking motion. Further, the motion detection unit 102 may detect, for example, a motion that swings upward or downward, or a motion that swings in the front direction or the back direction. Here, the vertical and horizontal directions of the electronic book page when the electronic book page is displayed on a display screen (not shown) of the electronic book display device 1 are the vertical and horizontal directions of the electronic book display device 1 here. . Moreover, the display screen side of the electronic book display device 1 is a front direction, and the opposite side is a back direction.

  The motion detection unit 102 includes, for example, a sensor that detects motion, and detects motion in one or more directions specified in advance by performing calculations or the like using the output of the sensor. As a sensor for detecting movement, for example, a triaxial gyro sensor, a triaxial acceleration sensor, or the like can be used. Note that processing for detecting movement in one or more directions specified in advance, such as the shaking movement described above, from the output of a sensor that detects movement is a known technique in JP 2010-94338 A and the like. Here, detailed description is omitted.

  The motion detection unit 102 can be realized by the above-described sensor, an MPU, a memory, and the like. The processing procedure of the motion detection unit 102 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  When the motion detection unit 102 detects a motion in one or more directions specified in advance, the processing unit 103 performs a process specified in advance according to the detected motion. Processing according to the detected motion is, for example, processing associated with the motion in advance according to the combination of the direction in which the motion is indicated and the type of motion indicated by the detected motion. Is to do. The process according to the detected movement is a process for displaying an electronic book page, a process for changing the displayed page, a process for switching an electronic book to be displayed, and a process for terminating the display of the electronic book. Or an operation of controlling the power supply of the electronic book display device 1. The operation for controlling the power is an operation for turning on or off the power. It does not matter what kind of processing is performed according to the movement. For example, when the motion detection unit 102 detects a right or left movement, a process of turning a page of an electronic book is performed. The page turning operation is an operation for displaying pages before and after the currently displayed page. For example, the processing unit 103 sets the page turning direction to a different direction depending on whether the detected movement is a movement to the right or a movement to the left. There are two page turning directions: a direction in which a page before the current page is displayed and a direction in which a page after the current page is displayed. Further, the processing unit 103 performs a process of turning off the power of the electronic book display device 1 when the motion detection unit 102 detects a movement that swings upward or downward, for example. Alternatively, when the electronic book display device 1 is turned off (here, “off” includes a suspend state, a sleep state, etc.), the power is turned on when a motion of shaking upward or downward is detected. You may make it perform the process to perform. In addition, when a movement to swing upward or downward is detected, instead of performing a process of turning off the power, a list of file names of electronic book information stored in the electronic book storage unit 101, a list of book names, A list of icons of electronic book information files may be displayed on a monitor or the like. The combination of the motion detected by the motion detection unit 102 and the processing performed by the processing unit 103 is an example, and the motion detection unit 102 moves other than the above (for example, in a direction perpendicular to the monitor surface). A motion of shaking back and forth) may be detected, and the processing unit 103 may perform processing other than the above, and any combination of these may be used. The operation detected by the motion detection unit 102 and the processing performed by the processing unit 103 when this motion is detected include, for example, the above-described motion information and information indicating the processing performed by the processing unit 103 (for example, processing content). And condition management information having process identification information, commands, and the like). For example, when the motion detected by the motion detection unit 102 is the motion indicated by the motion information included in one condition management information, the processing unit 103 performs a process included in the one condition management information. The condition management information is stored in, for example, a storage unit (not shown) in which the above-described movement information is stored. The condition management information may include movement information.

  In the present embodiment, the processing unit 103 includes a page information acquisition unit 1031, a display unit 1032, and a power supply control unit 1033, and executes processing according to the motion detected by the motion detection unit 102 using these. An example of the case will be described.

  Note that the processing unit 103 may further perform processing such as displaying an electronic book or turning the page of the electronic book in accordance with an operation received by a receiving unit (not shown) or the like.

  The processing unit 103 can usually be realized by an MPU, a memory, or the like. The processing procedure of the processing unit 103 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit). Further, the processing unit 103 may include a display device for displaying an electronic book.

  The page information acquisition unit 1031 acquires one or more page information from the electronic book information when the motion detection unit 102 detects a motion in one or more specified directions. For example, one or more pieces of page information are acquired according to information indicating processing included in the condition management information corresponding to the detected movement. For example, when the display unit 1032 described later does not display the page information of the electronic book information, the page information acquisition unit 1031 detects the movement in one or more directions specified in advance. One or more page information of the electronic book information stored in the electronic book storage unit 101 is read. In this case, the electronic book information read by the page information acquisition unit 1031 and the page information may be determined in any manner, and may be designated by default, for example. Alternatively, one or more pieces of page information of the electronic book information that was displayed at the end of the previous time may be displayed.

  Further, the page information acquisition unit 1031 is configured such that, for example, when the display unit 1032 described later displays one or more pieces of page information of the electronic book information stored in the electronic book storage unit 101, the operation detection unit 102 When motion in one or more directions specified in advance is detected, page information different from the currently displayed page information is acquired from the electronic book information according to the motion detected by the motion detection unit 102. Different page information is, for example, page information associated with different page numbers.

  For example, the page information acquisition unit 1031 has one or more pieces of page information before or after the currently displayed page information when the motion detection unit 102 detects a movement of shaking the electronic book display device 1 left or right. Is acquired from the electronic book information. The page information acquisition unit 1031 preferably acquires one or more pieces of page information in different directions depending on whether the motion detected by the motion detection unit 102 is shaken to the left or to the right. The different direction here is before or after the current page. Thus, page turning is performed according to the direction in which the electronic book display device 1 is swung. The page information acquisition unit 1031 normally acquires the previous or subsequent page information from the electronic book information for one page or one page of spread when detecting a shaking motion. However, when the motion detection unit 102 detects a motion that swings to the right or left due to a speed or acceleration equal to or higher than a predetermined threshold value, the previous or subsequent page information for a plurality of pages specified in advance according to the threshold value is displayed. You may make it acquire from electronic book information.

  Further, when a plurality of pieces of electronic book information are stored in the electronic book storage unit 101, the page information acquisition unit 1031 can be used when the motion detection unit 102 detects a movement that swings in one or more specified directions. One or more pieces of page information of electronic book information different from the electronic book information currently displayed may be acquired. The one or more directions specified in advance are, for example, upward or downward. Thereby, the electronic book used as a display object can be switched. The page acquired here may be, for example, page information of a page (for example, the first page) designated by default, or may be page information of a page displayed last. The electronic book information that is different from the currently displayed electronic book information may be determined in any way. For example, different electronic book information may be determined with respect to the currently displayed electronic book information in accordance with an order designated in advance. The order designated in advance is the name order of electronic books, the order of registration, and the like. Note that, depending on whether the detected motion is a motion that swings upward or downward, the electronic book is switched according to a pre-specified order, or along the reverse order of the pre-specified order. It may be different depending on whether the electronic book is switched.

  Note that the page information acquisition unit 1031 may further acquire, for example, page information of electronic book information specified by this operation in response to an operation received by a receiving unit (not shown) or the like.

  The page information acquisition unit 1031 can be usually realized by an MPU, a memory, or the like. The processing procedure of the page information acquisition unit 1031 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The display unit 1032 displays one or more page information acquired by the page information acquisition unit 1031. For example, when one or more page information is currently displayed, when the page information acquisition unit 1031 acquires page information corresponding to the operation detected by the operation detection unit 102, the display unit 1032 Update the display screen with information. The display unit 1032 may or may not include a display device. The display unit 1032 may be realized by display device driver software, or display device driver software and a display device.

  The power supply control unit 1033 turns off the electronic book display device 1 when the motion detection unit 102 detects a movement in one or more specified directions. For example, the power control unit 1033 may output a control signal instructing the end of power supply to a power supply unit (not shown) that supplies power to the electronic book display device 1 to turn off the power. For example, the power supply control unit 1033 turns off the power of the electronic book display device 1 when the motion detection unit 102 detects a movement that swings upward or downward. In addition, when the motion detection unit 102 detects a movement that turns the electronic book display device 1 back, the electronic book display device 1 may be turned off. The reverse movement is a movement of rotating the electronic book display device 1 about 180 degrees with respect to one axis.

  The power supply control means 1033 can be usually realized by an MPU, a memory, or the like. The processing procedure of the power control unit 1033 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  Here, as an example, the movement in one or more directions detected by the operation detection unit 102 corresponding to the process performed by the page information acquisition unit 1031 and the operation detection unit 102 corresponding to the process performed by the power supply control unit 1033 are detected. The movements in one or more directions are made to be non-overlapping movements. However, in the case where the processing performed by the page information acquisition unit 1031 and the processing performed by the power control unit 1033 may be executed in duplicate, the detected motions may be overlapping motions.

  Next, the operation of the electronic book display device 1 will be described using the flowchart of FIG.

  (Step S <b> 201) The electronic book display device 1 determines whether or not a reception unit (not shown) has received an instruction to display one electronic book stored in the electronic book storage unit 101. The instruction to display may include, for example, information specifying an electronic book to be displayed. If accepted, the process proceeds to step S202. If not accepted, the process returns to step S201.

  (Step S202) The page information acquisition unit 1031 acquires page information from the electronic book information stored in the electronic book storage unit 101 in accordance with the display instruction received in step S201. For example, the page information specified by default or the page information displayed at the end of the electronic book information is acquired from the electronic book information specified by the display instruction.

  (Step S203) The display unit 1031 displays the page information acquired by the page information acquisition unit 1031 on a monitor or the like (not shown).

  (Step S204) The motion detection unit 102 starts detecting motion. For example, a value indicating movement is repeatedly obtained by calculation using an output of a sensor that detects movement.

  (Step S <b> 205) The motion detection unit 102 determines whether a leftward movement is detected. For example, it is determined whether or not a value obtained by calculation from the output of the sensor is a value indicating a leftward movement. For example, it is determined whether or not the obtained value is a value indicating a motion of acceleration equal to or greater than a predetermined threshold value toward the left. If a leftward movement is detected, the process proceeds to step S206. If not detected, the process proceeds to step S208.

  (Step S206) The page information acquisition unit 1031 acquires page information next to the currently displayed page information. The next page information is, for example, page information in which the page number and the arrangement order are in the next order. If there is no next page information, the page information may be returned to the page information in the first order, or the page information of the electronic book information having the next output order with respect to the currently displayed electronic book information is acquired. May be.

  (Step S207) The display unit 1031 displays the page information acquired by the page information acquisition unit 1031 in step S206 or step S209 on a monitor or the like (not shown). For example, the monitor display is updated with the page information acquired in step S206 or step S209. Then, the process returns to step S205.

  (Step S <b> 208) The motion detection unit 102 determines whether or not a motion to swing to the right is detected. For example, it is determined whether or not a value obtained by calculation from the output of the sensor is a value indicating a rightward movement. If a motion to swing to the right is detected, the process proceeds to step S209, and if not detected, the process proceeds to step S210.

  (Step S209) The page information acquisition unit 1031 acquires the page information before the currently displayed page information. The previous page information is, for example, page information whose page number or arrangement order is the previous order. If there is no previous page information, the page information may be returned to the page information in the last order, or the page information of the electronic book information whose output order is the previous with respect to the electronic book information currently displayed is acquired. May be. Then, the process returns to step S207.

  (Step S <b> 210) The motion detection unit 102 determines whether or not a motion that swings up or down is detected. For example, it is determined whether or not a value obtained by calculation from the output of the sensor is a value indicating a movement that shakes up or down. If a motion to swing up or down is detected, the process proceeds to step S211. If not detected, the process returns to step S205.

  (Step S211) The power supply control unit 1033 turns off the power of the electronic book display device 1. Then, the process ends.

  Note that the motion detection processing of step S205 and step S208 may be interchanged.

  In the flowchart of FIG. 2, the process is terminated by powering off or a process termination interrupt.

  Hereinafter, a specific operation of the electronic book display device 1 in the present embodiment will be described. FIG. 3 is a conceptual diagram of the electronic book display device 1. Here, a case where the electronic book display device 1 is a multi-function mobile phone called a so-called smartphone will be described as an example. The electronic book display device 1 is assumed to be capable of touch panel operation. However, the electronic book display device 1 may be another device.

  FIG. 4 is an electronic book management table for managing electronic book information stored in the electronic book storage unit 101. The electronic book management table has items of “book ID” and “book data”. “Book ID” is identification information of electronic book information, and here, it is assumed that it is a file name of electronic book information. “Book ID” may be a book name of an electronic book. “Book data” is electronic book information.

  FIG. 5 is a diagram illustrating electronic book information stored in the electronic book storage unit 101. Here, electronic book information whose file name is “bk001” is shown. The electronic book information has items of “page ID” and “page information”. “Page ID” is page identification information, and here indicates a page number. “Page information” is page information and has content arranged on the page. In addition to the above, the electronic book information may include information such as the background color of the page and the font size, but the description thereof is omitted here. The electronic book information may be information in XML format, for example.

  First, it is assumed that the user operates the touch panel or the like of the electronic book display device 1 to give an instruction to display electronic book information whose file name is “bk001” on the electronic book display device 1.

  The page information acquisition unit 1031 acquires page information specified by default from electronic book information whose file name is “bk001” stored in the electronic book storage unit 101. Here, it is assumed that the page information specified by default is page information having a corresponding “page ID” of “1”. Specifically, a record whose “page ID” is “1” is detected from the electronic book information whose file name is “bk001” shown in FIG. 5, and the value of the “page information” is acquired. That is, the page information whose page number is “1” is acquired.

  The display unit 1032 displays the page information acquired by the page information acquisition unit 1031 on the monitor 30 of the electronic book display device 1.

  FIG. 6 is a diagram illustrating a display example of page information in which “page ID” is “1” by the display unit 1032.

Next, it is assumed that the user swings the electronic book display device 1 to the left. Here, the left is the direction indicated by the arrow 60 in FIG.
FIG. 7 shows information on the motion indicating the motion detected by the motion detection unit 102 and the processing performed by the processing unit 103 according to the detected motion, which are stored in advance in a storage unit such as a storage medium (not shown). It is a figure which shows the condition management information which manages. The condition management information includes items of “motion meaning”, “motion condition”, and “processing”. The “motion meaning” is information indicating the meaning of the motion to be detected, and may be considered as the name of the motion. The “motion condition” is information indicating a condition for detecting motion. For example, “x-axis vector: positive” is a condition indicating that the value of the x-axis vector is positive. “Acceleration in the x-axis direction: a or more” (where a is a positive value) is a condition indicating that the absolute value of the acceleration in the x-axis direction is a or more. Here, the x-axis direction indicates the same direction as the x-axis (lateral) direction of the monitor of the electronic book display device 1, and the right direction along the x-axis is a positive direction. Further, the y-axis direction indicates the same direction as the y-axis (vertical) direction of the monitor of the electronic book display device 1, and the upward direction along the y-axis is a positive direction. This “motion meaning” and “motion condition” are the above-described motion information. “Processing” is information indicating the processing content performed by the processing unit 103 when an operation satisfying the “motion condition” is detected. For example, when the processing content and the processing actually executed by the processing unit 103 are associated in advance, and one “processing” is selected, processing corresponding to the processing content is executed.

  A sensor that detects the motion of the motion detection unit 102 outputs information corresponding to the motion of the electronic book display device 1. Then, the motion detection unit 102 obtains information indicating the movement of the electronic book display device 1 by performing calculations and the like using this information. Here, as information indicating the direction in which the electronic book display device 1 has moved, the motion detection unit 102 acquires the value of the x-axis vector and the value of the y-axis vector. Moreover, the acceleration of the x-axis direction at the time of moving and the y-axis direction is acquired. Here, for example, it is assumed that a negative value is acquired as the vector value in the x-axis direction, and b (provided that b> a) is acquired as the acceleration in the x-axis direction. Then, the motion detection unit 102 sequentially determines in order from the top record whether or not the information indicating the acquired motion satisfies the “motion condition” of each record of the above-described condition management information. Here, since the value of the x-axis vector is negative and the acceleration b in the x-axis direction is a or more, “x-axis vector: negative,” which is the “motion condition” of the first record in the condition management information. In addition, it is determined that the condition “acceleration in the x-axis direction: a or more” is satisfied. For this reason, the motion detection unit 102 determines that the motion indicated by the “motion meaning” included in this record, that is, the motion shaken to the left is detected.

  The page information acquisition unit 1031 reads the next page information of the currently displayed page information from the electronic book information whose file name is “bk001” because the motion detection unit 102 has detected a movement to the left. . Since the “page ID” of the current page information is “1”, page information having a value “2” obtained by adding 1 to the value of “page ID” is acquired as the page information in the next order. Specifically, a record whose “page ID” is “2” is detected from the electronic book information whose file name is “bk001” shown in FIG. 5, and the value of the “page information” is acquired. That is, the page information whose page number is “2” is acquired.

  Then, the display unit 1032 updates the page information displayed on the monitor 30 with the page information acquired by the page information acquisition unit 1031.

  FIG. 8 is a diagram illustrating a display example of page information in which “page ID” is “2” by the display unit 1032.

  Next, it is assumed that the user swings the electronic book display device 1 to the right. The right here is assumed to be the direction indicated by the arrow 70 in FIG.

  The sensor that detects the motion of the motion detection unit 102 outputs information corresponding to the motion of the electronic book display device 1, and the motion detection unit 102 uses this information to indicate the direction in which the electronic book display device 1 has moved. As a result, an x-axis vector value and a y-axis vector value are obtained. Moreover, the acceleration of the x-axis direction at the time of moving and the y-axis direction is acquired. Here, for example, it is assumed that a positive value is acquired as the vector value in the x-axis direction, and c (provided that c> a) is acquired as the acceleration in the x-axis direction. Then, the motion detection unit 102 sequentially determines in order from the top record whether or not the information indicating the acquired motion satisfies the “motion condition” of each record of the above-described condition management information. Here, since the value of the x-axis vector is positive and the acceleration c in the x-axis direction is greater than or equal to a, it is determined that the “movement condition” of the first record is not satisfied. It is determined that the condition “x-axis vector: positive and x-axis direction acceleration: a or more”, which is the “movement condition” of the eye record, is satisfied. Therefore, the motion detection unit 102 determines that the motion indicated by the “motion meaning” included in the second record, that is, the motion to the right is detected.

  The page information acquisition unit 1031 reads the page information in the previous order of the currently displayed page information from the electronic book information whose file name is “bk001” because the motion detection unit 102 has detected a movement to the right. . Since the “page ID” of the current page information is “2”, page information having a value “1” obtained by subtracting 1 from the value of “page ID” is acquired as the next page information. Specifically, a record whose “page ID” is “1” is detected from the electronic book information whose file name is “bk001” shown in FIG. 5, and the value of the “page information” is acquired. That is, the page information whose page number is “1” is acquired.

  Then, the display unit 1032 updates the page information displayed on the monitor 30 with the page information acquired by the page information acquisition unit 1031. A display example of the page information is the same as that in FIG.

  Here, it is assumed that the user swings the electronic book display device 1 upward. Here, the top is the direction indicated by the arrow 61 in FIG.

  Similar to the above, the motion detection unit 102 uses the sensor values to acquire the x-axis vector value and the y-axis vector value, and the acceleration in the x-axis direction and the y-axis direction. Here, it is assumed that a positive value is acquired as the vector value in the y-axis direction and d (provided that d> a) is acquired as the acceleration in the x-axis direction. Then, the motion detection unit 102 sequentially determines whether or not the “motion condition” of each record of the condition management information is satisfied, in order from the upper record, and as a result, the “motion condition” of the first and second records. Is not satisfied, and it is determined that the condition management information satisfies the condition “y-axis vector: positive and acceleration in the x-axis direction: a or more”, which is the “movement condition” of the third record. To do. Then, the motion detection unit 102 determines that the motion indicated by the “motion meaning” included in the third record, that is, the motion to swing up is detected.

  Therefore, the power control unit 1033 performs an operation of turning off the power of the electronic book display device 1. As a result, the electronic book display device 1 is turned off. Here, the operation of turning off the power may be an operation of bringing the electronic book display device 1 into a substantially inactive state. For example, the electronic book display device 1 is put into a sleep state or a suspended state. Or a standby state. Alternatively, when the electronic book display device 1 is realized by causing a computer or the like to execute software, the software may be terminated.
