The front display unit 20 and the back display unit 30 will be described with reference to FIG.

FIG. 2 is a diagram showing an example of the appearance of the display device 10. The display device 10 includes a plate-shaped housing 40. 2A shows the front surface 41 of the housing 40, and FIG. 2B shows the back surface 42 of the back side of the housing 40. FIG. The front display unit 20 is a display provided with a front display surface 21 on the front surface 41, and is controlled by the control unit 11 to display an image on the front display surface 21. The back display unit 30 is a display provided with a back display surface 31 on the back surface 42, and is controlled by the control unit 11 to display an image on the back display surface 31. In the example of FIG. 2, the back display surface 31 is smaller than the front display surface 21 and has a different shape, but may be the same size and the same shape.

The front surface 41 and the back surface 42 (hereinafter referred to as “housing surface” if not distinguished from each other) have a rectangular shape with rounded corners. In the following, the direction along the short side of the casing surface is the X-axis direction, the direction along the long side is the Y-axis direction, and the direction along the perpendicular to the casing surface, that is, the direction perpendicular to the X-axis and Y-axis is the Z-axis. Let's say direction. In addition, the directions indicated by the arrows indicating the X axis, the Y axis, and the Z axis shown in the figure are each referred to as a positive direction, and the opposite direction is referred to as a negative direction. For example, FIG. 2C shows the display device 10 viewed in the positive direction of the X axis.

The angular velocity sensor of the sensor unit 15 shown in FIG. 1 is provided at the center A1 of the housing 40, for example, and the angular velocity (hereinafter “ The first angular velocity ”) and the angular velocity (hereinafter referred to as“ second angular velocity ”) when the apparatus rotates on the axis B2 that also passes through A1 and extends along the X-axis direction. The sensor unit 15 outputs a positive first angular velocity when the display device 10 rotates clockwise as viewed in the positive direction of the Y-axis (in the direction indicated by the arrow C1 in the figure), and in the opposite direction. When rotating in the negative direction, a negative first angular velocity is output.

The sensor unit 15 outputs a positive second angular velocity when the display device 10 rotates clockwise as viewed in the positive direction of the X axis (in the direction indicated by the arrow C2 in the figure).

Hereinafter, the rotation direction when the display device 10 rotates in the direction indicated by the arrow C <b> 1 is referred to as “lateral positive direction”, and the rotation direction when the display device 10 rotates in the opposite direction is referred to as “lateral negative direction”. The rotation direction when the display device 10 rotates in the direction indicated by the arrow C2 is referred to as “vertical positive direction”, and the rotation direction when the display device 10 rotates in the opposite direction is referred to as “vertical negative direction”.

[1-3] Functional Configuration The storage unit 12 of the display device 10 stores a display control program for controlling content display. The control unit 11 executes the display control program to control each unit, thereby realizing each function described below.
FIG. 3 is a diagram illustrating an example of a functional configuration of the display device 10. The display device 10 includes a first display unit 101, a second display unit 102, a detection unit 103, an acquisition unit 104, and a display control unit 105.

[1-3-1] First Display Unit and Second Display Unit The first display unit 101 is a unit that displays content on one side of the casing 40 (hereinafter referred to as “first side”). The display means 102 is a means for displaying content on the other surface (hereinafter referred to as “second surface”) of the housing 40. Content refers to web pages, SNS (Social Networking Service) posts, maps, e-mails, games, and the like, and each is represented by an image including a pattern, a character string, and the like. These contents are executed by executing a program (hereinafter referred to as “display program”) for displaying each content, such as a browser, SNS software, and mail software. 2 is displayed by the display means 102.

The first surface described above may be either the surface provided with the front display surface 21 or the surface provided with the back display surface 31. Further, the second surface described above may be either the surface on which the front display surface 21 is provided or the surface on which the back display surface 31 is provided. That is, in the display device 10, the front display unit 20 may be the first display unit 101 and the back display unit 30 may be the second display unit 102, or the front display unit 20 may be the second display unit 102 and the back display unit 30. May be referred to as the first display means 101.

Note that the display device 10 holds information (hereinafter referred to as “surface specifying information”) that specifies a surface that is visually recognized by the user among the first surface and the second surface. The surface indicated by the surface identification information as being visually recognized by the user is a so-called “front”, and the surface indicated as not being visually recognized is the “back”. Here, the display portion of the surface visually recognized by the user before the reversal is started is “first display means 101”, and the display portion of the opposite surface is “second display means 102”. For example, when the user is looking at the front display unit 20, the front display unit 20 is the first display unit 101, and the back display unit 30 is the second display unit 102. Alternatively, when the user is looking at the back display unit 30, the back display unit 30 is the first display unit 101, and the front display unit 20 is the second display unit 102.

[1-3-2] Detection Unit The detection unit 103 is a unit that detects that the direction of the one surface (first surface) and the direction of the other surface (second surface) are reversed. Hereinafter, “inversion” refers to rotation that satisfies a predetermined inversion condition. Specifically, inversion means that the direction of the first surface and the direction of the second surface are rotated by 180 °, for example. The detecting unit 103 acquires the above-described direction change information (information indicating a change in the direction of the display device 10), and the acquired direction change information satisfies a condition (inversion condition) set for determining whether or not to invert. When it is detected, it detects reverse.

In this embodiment, the detection means 103 acquires the measurement result by the sensor part 15 mentioned above, ie, the 1st and 2nd angular velocity, as direction change information. For example, the detection unit 103 may set one of values obtained by integrating the first and second angular velocities measured during a predetermined time (for example, 1 second or 3 seconds) as a threshold (for example, 170 degrees or 180 degrees). If it exceeds, it is determined that the inversion condition is satisfied, and inversion is detected.

For example, when the user who has been viewing the front display surface 21 rotates the display device 10 about the axis B1 in order to view the back display surface 31, the integrated value of the first angular velocity is 180 degrees. In this case, if a value less than 180 degrees is set as the threshold value, the detection means 103 detects the inversion because the integrated value of the first angular velocity exceeds the threshold value. In this way, in the present embodiment, the detection unit 103 detects the reversal about the axis B1 and the reversal about the axis B2 shown in FIG. When detecting the inversion, the detecting unit 103 supplies the display control unit 105 with detection notification information for notifying that and the direction change information used for the detection.

[1-3-3] Acquisition Unit The acquisition unit 104 is a unit that acquires a plurality of second contents related to the first content displayed by the first display unit 101. In the present embodiment, the acquisition unit 104 acquires the second content by the following two methods.
[1-3-3-1] First Acquisition Method In the first acquisition method, the acquisition unit 104 acquires the second content based on the history of content displayed by the user (hereinafter referred to as “display history”). get. This first acquisition method will be described with reference to FIG.

FIG. 4 is a diagram for explaining the first acquisition method. The acquisition unit 104, for example, each time content is displayed on the front display unit 20 and the back display unit 30, information for identifying the displayed content (hereinafter referred to as "identification information". For example, content URL (Uniform Resource Locator) Etc.) and the displayed time (hereinafter referred to as “display time”. In addition to the hour and minute, it may include second and year / month / day) are stored in the display history DB (Data Base). In this case, the identification information and the display time are accumulated in the display history DB as a display history. FIG. 4A shows an example of identification information and display time accumulated in the display history DB. In this example, content A is displayed first, followed by content B and then content C.

For example, it is assumed that the display device 10 is operated by the user and the content A is displayed on the table display unit 20. In this case, the acquisition unit 104 sets the table display unit 20 as the first display unit 101 and the content A as the first content. The acquisition unit 104 refers to the display history DB, and has the highest number of times the content is displayed next to the first content (hereinafter referred to as “next display number”) from content other than the first content (content A in this example). Content is acquired as second content. More specifically, the acquisition unit 104 executes a display program for displaying the second content (the above-described browser, SNS software, mail software, etc.), and acquires the second content by its function. Note that the acquisition unit 104 is not limited to this, and may execute an acquisition-dedicated program having a function for performing only acquisition without displaying the content, and may acquire the second content by the function.

FIG. 4 (b) shows other contents arranged in order from the one with the largest number of subsequent displays when the content A is the first content. In this example, the next display count of the content B is the largest, 20 times, and the contents E and G (the next display count is 10, 5 respectively) are in the following order. In this case, the acquisition unit 104 acquires the content B having the largest number of next displays as the second content. When the second content is acquired, the image of the display program and the second content are not displayed, and only reading and writing in the RAM and the storage unit 12 are performed. The acquisition unit 104 supplies the second content acquired in this way to the display control unit 105.

Note that the content described above may be, for example, a web page showing each end article, for example, in the case of a portal site of “XX newspaper company”, but is not limited thereto. For example, if a newspaper company provides articles by dividing them into categories such as social, economic, overseas, and sports, web pages showing articles included in those categories may be combined and handled as one content. . For example, the acquiring unit 104 determines that web pages that include a common domain name (such as “www.XX.com/sports/”) in the URL are the same content. In this way, for example, when the user displays the content “□ △ Newspaper Sports” ten times after the content “XX Newspaper Sports”, the displayed web page is different each time. Even so, the next display count is handled as 10 times.

On the other hand, in the above case, a single content includes a plurality of web pages. The acquisition unit 104 may acquire all of the plurality of web pages when acquiring the second content, but is not limited thereto. For example, when the URLs of the web pages have a hierarchical structure, the acquisition unit 104 may acquire only the top web page of them as the second content. In this case, for example, the acquisition unit 104 acquires, as the second content, a web page that is transmitted when only the domain name common to each web page is the destination.

[1-3-3-2] Second Acquisition Method In the second acquisition method, the acquisition unit 104 displays information for displaying other content on the first content (hereinafter referred to as “display information”. For example, hyper. If the link) is included, the content displayed by the display information is acquired as the second content. If the first content includes a plurality of pieces of display information, the acquisition unit 104 displays, for example, the content displayed by the display information whose displayed position is closest to a predetermined position (for example, the upper left corner) on the display surface. Obtained as second content. In addition, when the display information is included in the sentence, the acquisition unit 104 acquires the content displayed by the display information closest to the beginning of the sentence as the second content.

Note that the acquisition unit 104 selects, for example, the content that has been displayed by the user most frequently among the plurality of contents displayed by the plurality of pieces of display information based on the display history described in the first acquisition method. You may get as In this case, not only the number of times that the first content is displayed next but also the number of times that the other content is displayed next is included. The acquisition unit 104 also supplies the second content acquired in this way to the display control unit 105.
In the present embodiment, as described above, the acquisition unit 104 acquires two types of second content, that is, the second content acquired by the first acquisition method and the second content acquired by the second acquisition unit. .

[1-3-4] Display Control Unit When the inversion is detected by the detection unit 103, the display control unit 105 outputs the second content corresponding to the inversion method among the plurality of acquired second contents. 2 is a means for displaying on the display means 102. When the detection notification information is supplied from the detection unit 103, the display control unit 105 determines that reversal has been detected, and similarly determines the reversal method based on the direction change information supplied from the detection unit 103. The display control means 105 stores a determination table for determining how to invert (that is, a plurality of inversion definitions different from each other (in other words, inversion conditions)).

The “first display unit 101” and the “second display unit 102” here are the first display unit 101 (that is, the display unit of the surface specified by the surface specifying information) before the latest inversion is detected. And the second display means 102 (the display portion on the opposite side). That is, “display the second content in accordance with the manner of inversion on the second display means 102” means that the second content is displayed on the display unit that was the second display means 102 before the inversion is detected. Say. When the surface identification information is updated, the correspondence relationship between the front display unit 20 and the back display unit 30, and the first display unit 101 and the second display unit 102 is switched. Regardless of the timing of the replacement, The second content is displayed on the display unit which is the second display means. The surface identification information may be updated immediately when reversal is detected (in this case, the second content is displayed by the first display means 101 at that time), or the second content is displayed. It may be updated later (in this case, the second content is displayed by the second display means 102 at that time).

When the predetermined switching condition is satisfied, the surface identification information is updated. The switching condition may be, for example, the same as the inversion condition (that is, the surface specifying information may be updated at the same time as the inversion is detected). Alternatively, the switching condition may be a combination of an inversion condition and another condition (for example, a condition that the user touches the second display unit 102).

FIG. 5 is a diagram illustrating an example of the determination table. In this example, the direction change information “first angular velocity (positive)”, “first angular velocity (negative)”, “second angular velocity (positive)”, and “second angular velocity (negative)” includes “horizontal positive direction”. : “Α”, “horizontal negative direction: β”, “vertical positive direction: γ”, and “vertical negative direction: δ” are associated with each other (ie, four different inversion modes). Is defined). “(Positive)” and “(Negative)” described in the direction change information indicate whether each angular velocity is a positive value or a negative value. In addition, “α”, “β”, “γ”, and “δ” described in the method of inversion are symbols assigned to the methods of inversion for convenience of explanation. It is represented by the rotation direction of the display device 10 described before each symbol (the rotation direction described using the arrows C1 and C2 in the description of FIG. 2). The display control unit 105 determines the rotation direction associated with the supplied direction change information in the determination table as the reversal method in the detected reversal.

The display control means 105 stores a control table that associates the determined inversion method with the content to be displayed.

FIG. 6 is a diagram illustrating an example of the control table. In this example, “α” (horizontal positive direction), “β” (horizontal negative direction), “γ” (vertical positive direction), and “δ” (vertical negative direction) are reversed. , “Second content acquired by the first acquisition method”, “first content before inversion”, “second content acquired by the second acquisition method”, and “first content before inversion” The content to be associated is associated. The display control means 105 causes the second display means 102 to display the content associated with the determined inversion method in the control table by the function of the display program for displaying the content.

As described above, the acquisition unit 104 acquires two types of second content (obtained by the first and second acquisition methods, respectively). The display control unit 105 uses the control table shown in FIG. 6, so that when the inversion in the first inversion method (for example, α shown in FIG. 6) is detected, one type of second content (the first content) 1 is acquired), and when the inversion in the second inversion method (for example, γ shown in FIG. 6) different from the first inversion method is detected, the other The type of second content (obtained by the second acquisition method) is displayed.

The transition of content when content is displayed using the control table shown in FIG. 6 will be described with reference to FIG.

FIG. 7 is a diagram showing an example of content transition. In the example of FIG. 7, an initial state D1 in which the content A is displayed by the table display unit 20 is shown. When the inversion method α is determined in this state D1, the content B acquired by the first acquisition method is in the state D11 displayed by the back display unit 30. When the inversion method α is determined in the state D11, the content C acquired by the first acquisition method in the state D11 becomes the state D12 displayed by the front display unit 20.

When the surface identification information is updated, the display control means 105 turns off the display of the display portion (that is, the second display portion 102 at that time) of the surface that is not visually recognized by the user. Note that turning off the display may be turning off the backlight of the liquid crystal display or stopping the power supply to the liquid crystal display. Note that the display control means 105 may remain turned on without turning off the display of the second display unit 102.

Further, when the surface specifying information is updated, the display control unit 105 writes the identification information and the display time for the content displayed on the first display unit 101 after the switching in the display history DB.

On the other hand, when the inversion method β is determined in the state D11, the content A, which is the first content before the inversion, is displayed on the front display unit 20 and returns to the state D1. As described above, the display control unit 105 displays the second content (in this example, content B) on the second display unit 102 and then the inversion detected when the second content is displayed (in this example). If the reverse in the direction opposite to α) is detected by the detection unit 103, the first display unit 101 displays the first content (content A in this example) that was displayed before displaying the second content. To display. In the present embodiment, the horizontal positive direction and the horizontal negative direction are in a relationship opposite to each other, and the vertical positive direction and the vertical negative direction are in a relationship opposite to each other.

When the reversal method γ is determined in the state D1, the content D acquired by the second acquisition method is in the state D2 displayed by the back display unit 30. When the inversion method α is determined in this state D2, the content E acquired by the first acquisition method is in the state D21 displayed by the back display unit 30. In the state D21, display control similar to that in the state D11 is performed. When the reversal method γ is determined in the state D2, the content G acquired by the second acquisition method in the state D2 becomes the state D3 displayed by the front display unit 20. In the state D3, display control similar to that in the state D2 is performed. On the other hand, when the inversion method δ is determined in the state D2, the content A, which is the first content before the inversion, is displayed on the table display unit 20, and the state D1 is returned to.

For example, in the state D1 before inversion, there is no first content before inversion. When the inversion method β or δ is determined in this state, the display control unit 105 does not display any content even if it is inverted in this embodiment. However, the present invention is not limited to this. When the display control unit 105 determines the inversion method β (or δ) in a state where the first content before inversion does not exist, for example, when the inversion method α (or γ) is determined. Similarly, the second content may be displayed. Further, in that case, the display control means 105 may reverse the rotation directions corresponding to α and β and γ and δ in the subsequent inversion determination. That is, the horizontal positive direction is determined as β, the horizontal negative direction as α, the vertical positive direction as δ, and the vertical negative direction as γ. As a result, the second content is displayed even if the reversal is started from either the positive direction or the negative direction, and when reversed in the opposite direction, the first content is displayed again.

When the inversion method α is determined and displayed in the state D11, D12, D21, D22, D31, and D32 and displayed, the display control unit 105 determines that the inversion method γ is in the state D1. The display control is performed in the same way as. For example, in the state D11, the display control unit 105 uses the back display unit 30 on which the content B is displayed as the first display unit 101, and uses the content B as the first content and the second content acquired by the second acquisition method. Is displayed on the table display unit 20 which is the second display means 102. In the state where the inversion method γ has been determined once or more in the past as in the states D21, D22, D31, and D32, the display control unit 105 determines the inversion method δ and determines the latest inversion method γ. The first content before inversion when it is determined may be displayed on the display unit on the opposite side (the back display unit 30 in the state D21 and the front display unit 20 in the state D22). In this case, if the state is D21 and D22, the process returns to the state D1, and if the state is D31 and D32, the process returns to the state D2.

[1-4] Operation Based on the above configuration, the display device 10 performs a reverse display process for displaying the second content along with the reverse. The operation of the display device 10 in the reverse display process will be described with reference to FIG.

FIG. 8 is a flowchart showing an example of the operation of the display device 10 in the reverse display process. The reverse display processing is started when the user performs an operation for starting the display control program described above, for example (it may be started when the power is turned on. In this case, the operation for turning on the power is the starting operation). Is done. The display device 10 first activates a display control program (step S11). Next, the display device 10 determines whether content is displayed on the first display means 101 (one of the front display unit 20 and the back display unit 30) (step S12). The display device 10 initializes the surface specifying information at any timing so far. For example, the display device 10 determines that the display unit facing upward with respect to gravity is a display unit visually recognized by the user. Alternatively, the display device 10 may determine that the touch-operated display unit is a display unit visually recognized by the user.

If the display device 10 determines NO (NO) in step S12, the display device 10 performs the operation of step S12 again, and if it is determined that the content is displayed (YES), the displayed content is the first content. As described above, a plurality of second contents related to the first contents are acquired (step S13). Subsequently, the display device 10 determines whether or not inversion is detected (step S14). When the display device 10 determines NO (NO) in step S14, the display device 10 determines whether or not new content is displayed on the first display means 101 (step S15). In step S14, the operation returns to step S14. If the display device 10 determines that the new content is displayed (YES) in step S15, the display device 10 returns to step S13, and sets the new content as the first content (that is, updates the surface specifying information). 2 Acquire content.

The display device 10 displays new content when the user performs an operation to display another content while looking at the first display means 101 without performing inversion. Steps S13 and S15 are operations performed by the acquisition unit 104. If the display device 10 determines that reversal has been detected in step S14 (YES), the display device 10 determines the reversal method (step S16), and the determined reversal method among the plurality of second contents acquired in step S14. The second content corresponding to is displayed on the second display means 102 (step S17). Step S14 is an operation performed by the detection unit 103 and the display control unit 105. Step S16 is an operation performed by the display control unit 105, and step S17 is an operation performed by the display control unit 105 and the second display unit 102.

[1-5] Effects According to the First Embodiment In this embodiment, when the user displays any of the plurality of second contents on the second display means 102, a plurality of inversions as shown in FIG. It is only necessary to invert the display device 10 using any one of the methods. Therefore, when a plurality of contents can be displayed on the second display unit 102, for example, it is not necessary to perform an operation of selecting what is to be displayed from a list of these contents. As described above, according to the present embodiment, it is possible to reduce the trouble for a user who is looking at one side of the display device when viewing the content displayed on the other side even when a plurality of contents can be displayed. Can do.

In the present embodiment, the second content is acquired based on the display history described in the explanation of FIG. The display history, that is, the history of the content displayed by the user can easily represent the tendency of the user to display the content, as in the example of FIG. 4, the content B is often displayed next to the content A. According to this embodiment, by using such a display history, it is possible to acquire content that is relatively likely to be displayed by the user as the second content.

Further, in this embodiment, it is possible to display a certain type of second content or to display a different type of second content by using two ways of inversion. Thereby, when the user is not interested in one type of content, the user can try the other type of content. In the present embodiment, the display of content can be returned by performing the reverse in the opposite direction. Thereby, the user can display the content that has been displayed before and that the user wants to see again by an intuitive operation.

[2] Second Embodiment Hereinafter, a second embodiment of the present invention will be described focusing on differences from the first embodiment. In the second embodiment, the second content is acquired by two methods different from the first selection method.
[2-1] Third Acquisition Method In the third acquisition method, the acquisition unit 104 acquires second content according to the current time. The term here refers to a specific time of the day (such as commuting hours), a specific time of the week or January (such as the beginning of the week, the weekend, the beginning of the month or the end of the month), or the specification of the year (Such as year-end and New Year holidays, Golden Week, summer holidays, etc.). The acquisition unit 104 stores information indicating a predetermined specific time range by date and time, and specifies a time when the current date and time is included in the range.

The acquisition unit 104 extracts, for example, the display history including the display time at the specified time from the display history DB described in the first embodiment, and the next display shown in FIG. 4 when only the extracted display history is used. The content with the largest number of times is acquired as the second content. For example, when the specific time is a commuting time zone (from 7:00 to 9:00, etc.), in the example of FIG. 4, the next display count of the content B is the largest in the entire display history, but in the commuting time zone, for example, It is assumed that the next display number of the content E is the highest. In this case, the acquisition unit 104 acquires the content E as the second content.

For example, even if a user browses the content B most frequently after the content A in the entire display history, the content C related to that time is next to the content A at a specific time such as a commuting time zone. There are times when you browse the most. When the user is browsing the content A at that time, the user is more interested in the content C than the content B, and the third acquisition method acquires such content C as the second content. Accordingly, it is possible to easily display content that is likely to be displayed by the user as compared to the case of acquiring content regardless of the current time.

Note that the acquisition unit 104 may acquire the second content according to the current time by a method other than the above. For example, when a plurality of display information is included in the first content, the acquisition unit 104 includes a word / phrase related to the current time (hereinafter referred to as “time-related word / phrase”) among the contents displayed by the display information. ) Is acquired as the second content. In this case, the acquisition unit 104 stores a time-related phrase table in which a specific time is associated with a time-related phrase.

FIG. 9 is a diagram showing an example of the time-related phrase table. In the example of FIG. 9, a time related phrase “operation, traffic jam, weather, probability of precipitation, umbrella,. Are associated with time-related phrases such as “Year-end party, Christmas, New Year's Eve, Hatsumode, First sunrise, New Year's card, etc.”. When the acquisition unit 104 specifies that the current time is “commuting time zone”, the content is displayed in correspondence with the “commuting time zone” in the time-related phrase table among the contents displayed by the plurality of display information included in the first content. Get the ones that contain the most relevant terms.

In the example of FIG. 9, as described above, the content that includes the most time-related phrases is acquired as the second content. For example, a content in which a time-related phrase in the attendance time zone appears ten times tends to be more interested by a user in the attendance time zone than a content in which the same term-related phrase appears only once. Therefore, also in this case, it is possible to easily display the content that is likely to be displayed by the user, compared to the case of acquiring the content regardless of the current time.

[2-2] Fourth Acquisition Method In the fourth acquisition method, the acquisition unit 104 acquires the second content corresponding to the position where the own device is located. As shown in FIG. 1, the display device 10 includes a positioning unit 16. The positioning unit 16 measures the position of the own device using, for example, a GPS (Global Positioning System) technique. The positioning unit 16 supplies the control unit 11 with information indicating the measured position of the device, for example, as latitude and longitude. The acquisition unit 104 stores information indicating a predetermined area range by latitude and longitude, and specifies an area in which the measured position is included in the range. The area includes, for example, a city that covers Shibuya and Shinjuku, a city, a city, and a prefecture.

When acquiring the identification information and the display time in the display history DB described in the first embodiment, the acquiring unit 104 stores position information indicating the position of the own device in association with them. In this case, identification information, display time, and position information are accumulated in the display history DB as a display history. The acquisition unit 104 extracts the display history including the position information indicating the position included in the range of the area specified as described above, and the content having the largest number of next display times illustrated in FIG. 4 when only the extracted display history is used. Is acquired as the second content.

For example, even if a user browses the content B most frequently after the content A in the entire display history, the content C related to a store frequently visited in Shibuya is the second most popular after the content A. I often browse. When the user is in Shibuya and browsing the content A, the user is more interested in the content C than the content B. In the fourth acquisition method, such content C is acquired as the second content. As a result, it is possible to make it easier to display content that is likely to be displayed by the user than when content is acquired regardless of position information.

The acquisition unit 104 may acquire the second content according to the position where the own device is located by a method other than the above. For example, when a plurality of display information is included in the first content, the acquisition unit 104 includes a word / phrase (hereinafter referred to as “position-related”) related to the position where the device is located among the contents displayed by the display information. The content containing the largest number of “phrases” is acquired as the second content. In this case, the acquisition unit 104 stores a position-related phrase table that associates a specific area with a position-related phrase.

FIG. 10 is a diagram showing an example of the position-related phrase table. In the example of FIG. 10, a specific area “Near Shibuya” is associated with a location-related phrase “Dogenzaka, Shibuya Koen-dori, scramble intersection, center town,. Are associated with location-related phrases such as “Tokyo Metropolitan Government, Shinjuku Central Park, Shinjuku Street, Kabukicho,...”. When the acquisition unit 104 specifies that the current area is “Near Shibuya”, the acquisition unit 104 associates “Near Shibuya” with the position-related word / phrase table among the plurality of display information included in the first content. Get the one that contains the most position related phrases.

In the example of FIG. 10, as described above, the content that includes the most position-related words / phrases is acquired as the second content. For example, content in which a location-related phrase in the vicinity of Shibuya appears 10 times is more likely to be related to Shibuya than in content in which the same location-related phrase appears only once. User interest is likely to increase. Therefore, also in this case, it is possible to easily display the content that is likely to be displayed by the user as compared to the case of acquiring the content regardless of the position information.

[Modification]
Each embodiment mentioned above is only an example of implementation of the present invention, and may be modified as follows. Moreover, you may implement each embodiment mentioned above and each modification shown below, combining each as needed.

[3-1] Inversion Speed Display control means 105 may display the second content according to the inversion speed. In the present modification, for example, when the acquisition unit 104 acquires the second content, the acquisition unit 104 repeatedly acquires the content related to the acquired second content as new second content. The display control unit 105 acquires the second content (contents B, C, and J in the example of FIG. 11) acquired in order by the acquisition unit 104 in the order according to the reversal speed detected by the detection unit 103. The displayed second content is displayed. The display control unit 105 stores an order table in which the reversal speed and the order are associated with each other.

FIG. 11 is a diagram illustrating an example of the order table. In the example of FIG. 11, “3rd” and “2nd” are inversion speeds of “V1 or higher”, “less than V1 V2 or higher”, and “less than V2” (V1 represents a speed higher than V2). And the order “first” is associated. V1 or more means that the speed is faster than V1, and less than V1 means that the speed is slower than V1. A method in which the display control unit 105 displays the second content using the order table will be described with reference to FIG.

FIG. 12 is a diagram illustrating an example of the second content acquired in order. In the example of FIG. 12, as an example of the second content acquired in order, content B related to content A is acquired, content C related to content B is acquired, and content J related to content C is acquired. ing. When the inversion of the speed “V1 or higher” is detected while the content A is displayed on the first display unit 101, the display control unit 105 displays the content J, which is the second acquired second content. It is displayed on the second display means 102.

Further, when the reversal of the speed of “less than V1 and V2 or more” is detected, the display control unit 105 causes the second display unit 102 to display the content C that is the second acquired second content, and displays “less than V2”. ”Is detected, the second display unit 102 displays the content B that is the first acquired second content. According to this modification, for example, when it is not desired to view the second content directly related to the first content (when the same second content is displayed many times and the content is known, for example) The second content acquired after skipping the two content can be displayed.

In the example of FIG. 11, the order becomes earlier as the speed becomes smaller. On the contrary, the order may become later, and “No. 1”, “No. 3”, “No. 5” The order may be discontinuous. Also, the order may be neither ascending nor descending, such as “No. 1,” “No. 5,” and “No. 3.” Further, if the reverse rotation direction is opposite, the display control means 105 displays the first content that has been displayed retroactively in the order corresponding to the speed.

[3-2] Guide Image The display control unit 105 may display a guide image for guiding a display control method. The display control unit 105 displays, for example, an image (hereinafter referred to as “related image”) representing a method of inversion and a relationship between the second content corresponding to the inversion method as a guide image.
FIG. 13 is a diagram illustrating an example of the displayed relationship image. In the example of FIG. 13, the related image E10 displayed on the table display unit 20 is shown. The related image E10 includes an image E11 showing how to invert and images E12 and E13 showing contents displayed when the display device 10 is inverted.

The image E11 shows the display device 10, the axis of reversal, and an arrow indicating the rotation direction of the display device 10. The image E12 shows the second content displayed on the back display unit 30 when reversed in the horizontal positive direction, and the image E13 is displayed on the back display unit 30 when reversed in the vertical positive direction. The second content is shown. The second content shown in these images is a thumbnail image of the second content acquired by the acquisition unit 104, for example. As described above, the display control unit 105 displays the related image using the second content acquired by the acquisition unit 104.

Note that the display control means 105 may display a related image expressed by a method different from the example of FIG. For example, instead of a thumbnail image of the second content, a character string that briefly explains the method of acquiring the second content is displayed. For example, in the case of the first acquisition method, the display control means 105 displays a character string such as “the content that you will often browse next is displayed”. The content that you often browse among the linked content is displayed. " As described above, according to the present modification, it is possible to inform the user what content is displayed when the display device 10 is inverted.

[3-3] Guide image 2
In addition to the example of FIG. 13, for example, the display control unit 105 may display, as a guide image, an image representing a list of second contents to be displayed every time the image is reversed (hereinafter referred to as “list image”).
FIG. 14 is a diagram illustrating an example of the displayed list image. In the example of FIG. 14, a list image F10 displayed on the table display unit 20 is shown. Content A is also displayed on the table display unit 20, and the list image F10 is displayed so as to overlap the content A.

The list image F10 includes the content A that is the first content that is currently displayed, the contents B, C, and J that are the second content that are displayed when the display device 10 is flipped horizontally. Contents D and G, which are the second contents displayed when the apparatus 10 is inverted in the vertical direction, are shown. Each second content shown in the list image F10 is a thumbnail image of the second content acquired by the acquisition unit 104, for example. As described above, the display control unit 105 displays the list image using the second content acquired by the acquisition unit 104. According to this modification, it is possible to inform the user what content is displayed when the display device 10 is repeatedly inverted.

[3-4] Inversion Detection The method by which the detection unit 103 detects inversion is not limited to the above. For example, if the sensor unit 15 includes an acceleration sensor and the acceleration sensor is provided at a position away from the center A1 of the housing 40, the acceleration sensor also moves and accelerates when the display device 10 is inverted. Will be measured. For example, the detection unit 103 stores a range of acceleration measured at the time of inversion, and can detect the inversion when the inversion condition is satisfied when the acceleration included in the range is measured. When the sensor unit 15 includes a geomagnetic sensor, the change in orientation indicated by the measurement result of the geomagnetic sensor represents the change in orientation of the display device 10. Good.

Moreover, the detection means 103 may detect inversion based on the measurement results of a plurality of types of sensors. In that case, the reversal can be detected with higher accuracy. In addition, when the display device 10 includes an imaging unit that captures images on both the front surface 41 side and the back surface 42 side, the detection unit 103 may detect inversion based on the captured images. For example, the detection unit 103 recognizes a face included in the photographed image, and detects reversal when a face recognized on one surface side of the housing 40 is recognized on the other surface side. In addition, the detection unit 103 may detect inversion using a known technique.

[3-5] Inversion Method The definition of inversion (that is, the inversion condition) is not limited to that described in the embodiment. The inversion condition may be any as long as it limits one or more (preferably two or more) of the rotation axis, rotation direction, rotation amount (rotation angle), and rotation speed. For example, rotation about an axis that forms an angle in the X-axis direction or the Y-axis direction (that is, an axis inclined obliquely with respect to the vertical direction or the horizontal direction) as a rotation axis may be defined as inversion. Rotation with the axis away from A1 as the rotation axis may be defined as inversion. In the example of FIG. 5, four ways of reversal (definition) are shown. However, the number may be three or less, or may be five or more. Further, the number of inversion axes may be three or more, or one. When there is one reversal axis, for example, different reversal methods may be expressed depending on the reversal speed. In short, in the display device, two or more different inversion methods (definitions) may be used.

[3-6] Second Content Acquisition Method The acquisition unit 104 may acquire the second content by a method different from the embodiment. For example, the acquisition unit 104 may acquire the second content according to the user attribute. In this case, the acquisition unit 104 reads the user attribute stored in the storage unit 12 of the own device or the external device, and includes the most words / phrases related to the user attribute (hereinafter referred to as “attribute-related words / phrases”). Content is acquired as second content. The acquisition unit 104 stores an attribute-related phrase table in which user attributes are associated with attribute-related phrases.

FIG. 15 is a diagram illustrating an example of an attribute-related phrase table. In this example, an attribute-related phrase “sports, soccer, baseball, rugby, basketball,...” Is associated with a user attribute “hobby is sport or sports experience”, An attribute-related phrase such as “dinner, dinner, lunch, restaurant, French, Italian,...” Is associated with the user attribute “meal cost is a certain amount or more”. Using the attribute-related phrase table, the acquisition unit 104 acquires the second content, for example, in the same manner as when using the time-related phrase table shown in FIG. As a result, content that is related to user attributes and that is likely to be of high interest to the user is acquired as the second content.

[3-7] Acquisition of Two or More Second Contents In the above example, the acquisition unit 104 acquires one second content by one acquisition method. However, the present invention is not limited to this, and two or more second contents are acquired. You may get it. For example, in the example of FIG. 4, the acquisition unit 104 acquires the second content B, E from the one with the highest next display count as the second content. Thus, as the second content acquired by the acquisition unit 104 increases, the choices of the second content that can be displayed by the user can be increased.

[3-8] Display of a plurality of second contents The display control means 105 may cause the second display means 102 to display two or more second contents. For example, when the acquisition unit 104 acquires three or more second contents, the display control unit 105 stores a display control table in which two or more contents to be displayed for one reversal method are associated. . The display control unit 105 causes the second display unit 102 to display two or more contents associated with the inversion method in the display control table. In that case, the display control means 105 displays two or more contents in each area obtained by dividing the display surface of the second display means 102, or displays a list of contents to display the contents selected from the list. Just do it. Thereby, the user can browse more contents.

[3-9] Category of Invention The present invention can also be regarded as a display method for realizing the processing performed by the display device. The process here is, for example, the display control process shown in FIG. The present invention can also be understood as a program executed by a computer such as a display device. This program may be provided in the form of a recording medium such as an optical disk storing the program, or may be provided in the form of being downloaded to a computer via a network such as the Internet, and making it available for installation. You may do.
