Description

[Technical field]

[0001] The present invention relates to a system, a control program, and a control method for providing a skin. [Background technology]

[0002] Music playback applications installed on personal computers (hereafter referred to as "PCs"), digital audio players (hereafter referred to as "DAPs"), smartphones, etc., may offer a skin switching function that allows users to change the external design by changing the skin, which is data that records information about the appearance of the user interface windows, text, buttons, etc. on the operating screen.

[0003] However, when a user wants to use the skin switching function, he or she must check whether the application has the function and find out which screen allows skin switching. Furthermore, the user must manually perform the cumbersome tasks of searching for a preferred skin from among many skins, and, in the case of paid skins, purchasing the skin. Even if a developer prepares many paid skins, there is a high possibility that users will not be aware of the skin switching function or the paid skins that are on sale, and there are cases where purchasing opportunities are missed. This poses a problem for developers, as it does not lead to profits or sales.

[0004] Patent Document 1 discloses an invention that allows the skin to be changed without depending on the user's request, and Patent Document 2 discloses an invention that automatically switches to a skin that corresponds to a music file in a music player.

[0005] [Patent Document 1] Special Publication No. 2003-532189 [Patent Document 2] Special Publication No. 2015-531085 Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, there is a problem in that the user must manually perform cumbersome tasks when determining whether or not the skin switching function is available.

[0007] An object of the present invention is to allow a user to easily recognize whether or not a skin has been switched. [Means for solving the problem]

[0008] The system of a first invention is a system comprising an electronic device and a server, wherein the electronic device comprises a display unit and a control unit, and the control unit transmits music information, which is information relating to music, to the server, receives skin information, which is information including at least the presence or absence of a skin, transmitted from the server, and displays the received skin information on the display unit, and the server receives the music information transmitted from the electronic device, and transmits skin information corresponding to the received music information to the electronic device.

[0009] In the present invention, the control unit of the electronic device causes the display unit to display skin information corresponding to music information, which is information related to music, i.e., the presence or absence of skin. This allows the user to recognize the presence or absence of skin corresponding to the music displayed on the display unit of the electronic device. Furthermore, the skin information allows the user to easily recognize the presence or absence of a skin switching function without the need for complicated work. In this way, according to the present invention, the user can easily recognize the skin switching function.

[0010] The system of the second invention is characterized in that, in the system of the first invention, the server receives music information, searches for a skin corresponding to the received music information, and if a corresponding skin is found, sends skin information including information that a skin is found to the electronic device, and if a corresponding skin is not found, sends skin information including information that a skin is not found to the electronic device.

[0011] The system of the third invention is characterized in that, in the system of the second invention, the server sends skin information to the electronic device if a corresponding skin is available, the skin information including information that a skin is available and the contents of the skin.

[0012] It should be noted that the "contents of the skin" includes any information such as identification information (ID) indicating the skin, the title of the skin, and the like.

[0013] The system of the fourth invention is characterized in that, in any of the systems of the first to third inventions, when the control unit receives skin information from the server including information that a skin is available, it causes the display unit to display information inquiring as to whether or not to purchase the skin.

[0014] The system of the fifth invention is characterized in that, in the system of any of the first to third inventions, when the control unit receives skin information from the server, the skin information including information that a skin is available and the contents of the skin, the control unit displays information inquiring about whether or not to purchase the skin and the contents of the skin on the display unit.

[0015] In the present invention, when the server has a skin corresponding to the music information, the control unit receives the content of the skin from the server and displays it. This allows the user to easily check the content of the skin corresponding to the music information. The control unit also displays information on whether or not to purchase the skin on the display unit. This allows the user to easily proceed to the step of purchasing the skin if they check the content of the skin and wish to purchase it.

[0016] The system of a sixth invention is characterized in that, in the system of the fourth or fifth invention, the control unit displays information on the display unit inquiring as to whether or not to purchase a skin, and then accepts a selection of whether or not to purchase a skin.

[0017] The system of a seventh invention is characterized in that, in the system of the sixth invention, when the control unit accepts a selection to purchase a skin, it transmits a selection to purchase the skin to the server.

[0018] In addition, since the number of servers is not limited to one, the expression "the server" includes cases where the server is the same server and cases where the server is a different server.

[0019] The system of the eighth invention is characterized in that, in the system of the seventh invention, the server sends a skin corresponding to the music information to the electronic device when it receives a selection to purchase a skin.

[0020] The system of a 9th invention is characterized in that, in the system of the 8th invention, when the control unit receives a skin, it causes the display unit to display information inquiring as to whether or not to switch to the received skin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] Hereinafter, an embodiment of the present invention will be described. FIG. 1 is a block diagram showing a configuration of a system 201 according to an embodiment of the present invention. The system 201 includes a smartphone 1 and a server 101. The smartphone 1 and the server 101 communicate with each other via a network such as the Internet. In this embodiment, the smartphone 1 displays information about skins stored in the server 101. The smartphone 1 then accepts a purchase of a skin and receives the skin for which the purchase has been accepted from the server 101.

[0054] 1, a smartphone 1 (electronic device) includes a control unit 2, a storage unit 3, a display unit 4, an operation unit 5, a speaker 6, a headphone terminal 7, an input / output interface (hereinafter referred to as "input / output I / F") 8, a network communication unit (hereinafter referred to as "NW communication unit") 9, a Bluetooth (registered trademark) (hereinafter referred to as "BT") communication unit 10, etc. In this embodiment, the smartphone 1 is described as an example of an electronic device constituting the system 201, but the electronic device is not limited to this and may be a tablet PC or the like.

[0055] The control unit 2 includes a central processing unit (CPU), a digital signal processor (DSP), a memory, and the like, and controls each unit constituting the smartphone 1.

[0056] The storage unit 3 is composed of a flash memory that stores programs such as an OS (Operating System) program, application programs including a music playback application program (hereinafter referred to as a "music playback application P"), and various data such as digital audio data.

[0057] The storage unit 3 also stores purchase information 31, which is information indicating that a skin has been purchased. The purchase information 31 is stored in the storage unit 3 when the user selects to purchase a skin presented by the smartphone 1 and the selected skin is received from the server 101 by the smartphone 1. The purchase information 31 includes the contents of the skin (e.g., the title of the skin). In other words, the purchase information 31 corresponds to the purchase history of the skin. FIG. 2 is a diagram showing an example of the purchase information 31. As shown in FIG. 2, the purchase date and time of the skin (e.g., 2021 / 10 / 08 12:06) and the title of the skin (e.g., skin X) are stored as the purchase information 31. The storage unit 3 may also store purchase refusal information, which is information indicating that the skin will not be purchased. The purchase refusal information is stored in the storage unit 3 when the user does not select to purchase the skin presented by the smartphone 1. The purchase refusal information is information indicating that the user of the music playback app P will not purchase the skin (refuses to purchase the skin).

[0058] The storage unit 3 is not limited to the configuration shown in the example, and may be a hard disk drive (HDD) etc. The music playback application P may be installed (pre-installed) when the smartphone 1 is shipped from the factory, or may be installed after the smartphone is shipped from the factory.

[0059] The display unit 4 displays various images (including still images and moving images) and is configured with a liquid crystal panel. The operation unit 5 has operation keys for performing various settings, and a touch panel linked to the display unit 4. A user can input various characters such as a phone number and an email address, and perform communication settings, etc., via the operation unit 5. The speaker 6 outputs various sounds such as a call sound based on an audio signal. The headphone terminal 7 is for connecting headphones. An audio signal is output to the headphones via the headphone terminal 7. The input / output I / F 8 functions as an interface for the smartphone 1 to perform data communication with peripheral devices not shown.

[0060] The NW communication unit 9 is configured to be able to connect to the Internet via a mobile phone network and a mobile base station (not shown). The smartphone 1 can make calls and communicate with other terminals via the NW communication unit 9. The control unit 2 communicates with a server 101 via the NW communication unit 9.

[0061] The BT communication unit 10 is for performing wireless communication with a peripheral device (not shown) that supports the BT standard based on the BT standard.

[0062] The server 101 includes a database 102. In the database 102, music information, which is information related to music, and skins are stored in association with each other. FIG. 3 is a diagram showing an example of the database 102. As shown in FIG. 3, the music information includes, for example, a song title, an artist name, a genre, and the like. The music information and the skins (for example, information indicating a storage location of the skin) are stored in the same record of the database 102, whereby the music information and the skins are stored in association with each other.

[0063] For example, in the record numbered "1", "song A" is stored as the song title, "artist A" as the artist name, "genre A" as the genre, and "skin A (information indicating the storage location of skin A)" as the skin. The server 101 periodically updates the stored song information and skins. The database 102 is updated, for example, by information provided by the developer. For example, when the database 102 is updated, it is updated from the state shown in FIG. 3 to the state shown in FIG. 4. Here, when "skin A" associated with the song information stored in the record numbered "1" has been changed to "skin A'" in the information provided by the developer, the server 101 updates "skin A" to "skin A'". Also, when "skin B" associated with the song information stored in the record numbered "2" has been deleted, the server 101 deletes "skin B". When music information (song D, artist D, etc.) and the corresponding "skin D" have been added, the server 101 newly adds the music information and "skin D" to the record numbered "4."

[0064] (First embodiment) Next, in this embodiment, the processing operation of the smartphone 1 when the music playback application P stored in the storage unit 3 is executed will be described with reference to the flowchart shown in FIG. 5. First, in order to start the music playback application P, the user taps, for example, the icon of the music playback application P displayed on the display unit 4. The control unit 2 of the smartphone 1 accepts the tap by a touch panel linked to the display unit 4 and starts the music playback application P. After the music playback application P is started, the control unit 2 judges whether a song is being played (S1). If the control unit 2 judges that a song is being played (S1: Yes), it transmits information about the song being played (song title, artist name, genre, etc.) to the server 101, thereby inquiring whether the server 101 has a skin corresponding to the song information (S2). In this embodiment, the user is prompted (recommended) to purchase a skin corresponding to the song being played.

[0065] The server 101 receives music information transmitted from the smartphone 1. The server 101 searches for a skin corresponding to the received music information among the skins stored in the database 102. The server 101 transmits skin information, which is information including the presence or absence of a skin corresponding to the received music information, to the smartphone 1. If, as a result of the search, there is no skin corresponding to the received music information, the server 101 transmits skin information including information to the effect that there is no skin to the smartphone 1. Furthermore, if there is a skin corresponding to the received music information, the server 101 transmits skin information including information to the effect that there is a skin and the contents of the skin to the smartphone 1.

[0066] The control unit 2 receives skin information from the server 101, and determines whether or not there is a skin that corresponds to the transmitted music information based on the skin information received from the server 101 (S3). If the control unit 2 determines based on the skin information received from the server 101 that there is no skin that corresponds to the music information (S3: No), the control unit 2 ends the process. If the control unit 2 determines based on the skin information received from the server 101 that there is a skin that corresponds to the music information (S3: Yes), the control unit 2 determines based on the purchase information 31 whether or not the skin included in the skin information received from the server 101 has been purchased (S4).

[0067] When the control unit 2 determines that the skin included in the skin information received from the server 101 has already been purchased (S4: Yes), the process ends. The reason for ending the process is that the purchase information 31 includes that the skin has been purchased, and since the skin has already been purchased, there is no need to prompt (recommend) the user to purchase the skin again. When the control unit 2 determines that the skin has not been purchased (S4: No), it determines whether or not purchase refusal information is stored in the storage unit 3 (S5). When the control unit 2 determines that purchase refusal information is stored in the storage unit 3 (S5: Yes), the process ends. The reason for ending the process is that purchase refusal information is stored in the storage unit 3 and the user has no intention of purchasing the skin. When the control unit 2 determines that purchase refusal information is not stored in the storage unit 3 (S5: No), it causes the display unit 4 to display information inquiring whether or not to purchase the skin and the contents of the skin (S6). This is because purchase refusal information is not stored in the storage unit 3 and the user has an intention of purchasing the skin.

[0068] At this time, since music is being played on the smartphone 1, information inquiring whether or not to purchase a skin and the contents of the skin are displayed on the playback screen. FIG. 8(a) is a diagram showing an example of the playback screen. On the playback screen, an album jacket, a title (for example, title A), and an artist name (artist A) are displayed. On the playback screen shown in FIG. 8(a), information inquiring whether or not to purchase a skin and the contents of the skin are displayed as shown in FIG. 8(b). As the information inquiring whether or not to purchase a skin, a message "Do you want to purchase a skin?" is displayed. In addition, as the contents of the skin, the title of the skin (skin A) and, although not shown, a part of the skin (design) are displayed within a frame surrounding the title of the skin "skin A". In addition, a "YES" button and a "NO" button are displayed to accept the user's selection of whether or not to purchase the skin.

[0069] Next, the user selects whether or not to purchase a skin by touching a touch panel (display unit 4) (for example, the above-mentioned "YES" button or "NO" button). The control unit 2 accepts the selection of whether or not to purchase a skin based on the area touched by the user (S7, see FIG. 8(b)). If the control unit 2 accepts the selection to purchase a skin (S7: Yes), it transmits information to the server 101 indicating that a selection has been made to purchase a skin, as a skin purchasing process (S9). When the server 101 receives the information indicating that a selection has been made to purchase a skin, it transmits the skin corresponding to the music information to the smartphone 1.

[0070] When the control unit 2 receives the skin, it stores the contents of the skin in the purchase information 31 stored in the storage unit 3 (S10). Next, the control unit 2 displays information inquiring whether to switch to the purchased skin on the display unit 4, and accepts the selection of whether to switch to the purchased skin based on the area touched by the user (S11). FIG. 9 is a diagram showing the information inquiring whether to switch to the received skin. As shown in FIG. 9, a message "Switch to the purchased skin?" is displayed as the information inquiring whether to switch to the skin. In addition, a "YES" button and a "NO" button are displayed to accept the selection of whether to switch or not switch the skin by the user. The user selects (touches) the "YES" button or the "NO" button to select whether to switch to the purchased skin.

[0071] When the control unit 2 receives a selection to switch the skin (S11: Yes), it switches to the skin corresponding to the purchased music information (S12). When the control unit 2 receives a selection not to switch the skin (S11: No), it ends the process. Therefore, the skin cannot be switched. When the control unit 2 receives a selection not to purchase the skin (S7: No), it stores purchase refusal information in the storage unit 3 (S8).

[0072] Second embodiment Next, in this embodiment, the processing operation of the smartphone 1 when the music playback application P is executed will be described with reference to the flowcharts shown in Fig. 6 and Fig. 7. This embodiment differs from the first embodiment in that the start of the music playback application P is used as a trigger to check whether skin information is stored (S31 (Fig. 7) described later).

[0073] First, in order to launch the music playback application P, the user taps, for example, an icon of the music playback application P displayed on the display unit 4. The control unit 2 of the smartphone 1 receives the tap by using a touch panel linked to the display unit 4, and launches the music playback application P. After the music playback application P is launched, the control unit 2 determines whether or not a song is being played (S21). If the control unit 2 determines that a song is being played (S21: Yes), it transmits information about the song being played to the server 101, thereby inquiring of the server 101 as to whether or not there is a skin corresponding to the song information (S22). In this embodiment, the user is prompted (recommended) to purchase a skin corresponding to the song being played.

[0074] The server 101 receives music information transmitted from the smartphone 1. The server 101 searches for a skin corresponding to the received music information among the skins stored in the database 102. The server 101 transmits skin information, which is information including the presence or absence of a skin corresponding to the received music information, to the smartphone 1. If, as a result of the search, there is no skin corresponding to the received music information, the server 101 transmits skin information including information to the effect that there is no skin to the smartphone 1. Furthermore, if there is a skin corresponding to the received music information, the server 101 transmits skin information including information to the effect that there is a skin and the contents of the skin to the smartphone 1.

[0075] The control unit 2 receives skin information from the server 101, and determines whether or not there is a skin corresponding to the transmitted music information based on the skin information received from the server 101 (S23). If the control unit 2 determines based on the skin information received from the server 101 that there is no skin corresponding to the music information (S23: No), the control unit 2 ends the process. If the control unit 2 determines based on the skin information received from the server 101 that there is a skin corresponding to the music information (S23: Yes), the control unit 2 determines based on the purchase information 31 whether or not the skin included in the skin information received from the server 101 has been purchased (S24).

[0076] When the control unit 2 determines that the skin included in the skin information received from the server 101 has already been purchased (S24: Yes), the process ends. The reason for ending the process is that the purchase information 31 includes that the skin has been purchased, and since the skin has already been purchased, there is no need to prompt (recommend) the user to purchase the skin again. When the control unit 2 determines that the skin has not been purchased (S24: No), it determines whether or not purchase refusal information is stored in the storage unit 3 (S25). When the control unit 2 determines that purchase refusal information is stored in the storage unit 3 (S25: Yes), it ends the process. The reason for ending the process is that purchase refusal information is stored in the storage unit 3 and the user has no intention of purchasing the skin. When the control unit 2 determines that purchase refusal information is not stored in the storage unit 3 (S25: No), it stores the skin information and the contents of the skin in the storage unit 3 (S26). In order to end the music playback application P, the user taps, for example, the "Exit button" displayed on the display unit 4. The control unit 2 of the smartphone 1 receives a tap via a touch panel linked to the display unit 4, and ends the music playback application P (S27).

[0077] Next, the user taps, for example, an icon of the music playback application P displayed on the display unit 4 to start the music playback application P. The control unit 2 of the smartphone 1 accepts the tap by a touch panel linked to the display unit 4 and starts the music playback application P. After the music playback application P is started, the control unit 2 judges whether or not skin information and the contents of the skin are stored in the storage unit 3 (S31). If the control unit 2 judges that the skin information and the contents of the skin are not stored (S31: No), it ends the process. The reason for ending the process is that since the skin information and the contents of the skin are not stored in the storage unit 3, it is not necessary to prompt (recommend) the user to purchase the skin. If the control unit 2 judges that the skin information and the contents of the skin are stored in the storage unit 3 (S31: Yes), it causes the display unit 4 to display information inquiring whether or not to purchase the skin and the contents of the skin (S32). This is because the skin information and the contents of the skin are stored in the storage unit 3, and it is necessary to prompt (recommend) the user to purchase the skin.

[0078] Next, the user selects whether or not to purchase a skin by touching a touch panel (display unit 4) (for example, the "YES" button or the "NO" button in FIG. 8(b)). The control unit 2 accepts the selection of whether or not to purchase a skin based on the area touched by the user (S33). If the control unit 2 accepts the selection to purchase a skin (S33: Yes), it transmits information to the server 101 indicating that a selection has been made to purchase a skin, as a skin purchasing process (S34). When the server 101 receives the information indicating that a selection has been made to purchase a skin, it transmits the skin corresponding to the music information to the smartphone 1.

[0079] When the control unit 2 receives the skin, it stores the content of the skin, etc. in the purchase information 31 stored in the memory unit 3 (S35). Next, the control unit 2 displays information (see FIG. 9) inquiring whether to switch to the purchased skin on the display unit 4, and accepts the selection of whether to switch the purchased skin based on the area touched by the user (S36).

[0080] When the control unit 2 receives a selection to switch the skin (S36: Yes), the control unit 2 switches to the skin corresponding to the purchased music information (S37). When the control unit 2 receives a selection not to switch the skin (S36: No), the control unit 2 ends the process. Therefore, the skin cannot be switched.

[0081] As described above, in this embodiment, the control unit 2 of the smartphone 1 causes the display unit 4 to display skin information corresponding to music information, which is information related to music, i.e., the presence or absence of skin. This allows the user to recognize the presence or absence of skin corresponding to the music displayed on the display unit 4 of the smartphone 1. Furthermore, the skin information allows the user to easily recognize the presence or absence of skin switching without the need for complicated work. In this way, in this embodiment, the user can easily recognize the skin switching function.

[0082] Furthermore, in this embodiment, when the server 101 has a skin corresponding to the music information, the control unit 2 receives the contents of the skin from the server 101 and displays them on the display unit 4. This allows the user to easily check the contents of the skin corresponding to the music information. The control unit 2 also displays information on whether or not to purchase the skin. This allows the user to easily move on to the step of purchasing the skin if they wish to purchase it after checking the contents of the skin.

[0083] Furthermore, in this embodiment, when a skin is received, i.e., when a skin is purchased by the user, the control unit 2 causes the display unit 4 to display a facial expression inquiring whether or not to switch to the skin, and then accepts the selection of whether or not to switch to the skin. This allows the user to decide whether or not to switch to the purchased skin, and allows switching of skins without the need for complicated operations.

[0084] In this embodiment, when the control unit 2 receives a skin, it switches to the received skin. This allows the user to switch to the purchased skin without the need for complicated operations, simply by selecting to purchase the skin.

[0085] Furthermore, in this embodiment, when the control unit 2 receives a selection not to purchase a skin, or when the purchase of a skin corresponding to a song is rejected by the user, the control unit 2 stores purchase refusal information, which is information to the effect that the skin will not be purchased, in the storage unit 3. Then, when the purchase refusal information is stored in the storage unit 3, the control unit 2 does not display information inquiring whether or not to purchase a skin on the display unit 4. This prevents the user from having skin information displayed on the display unit 4 multiple times, and the user does not need to perform the same task multiple times, which saves the user trouble.

[0086] Furthermore, in this embodiment, the control unit 2 determines whether or not skin information and skin contents are stored in the storage unit 3 based on a predetermined trigger (for example, when the smartphone 1 is powered on, when an application for playing music is activated, or when music playback starts). If the control unit 2 determines that skin information is stored in the storage unit 3, it causes the display unit 4 to display skin information including information inquiring whether or not to purchase a skin and the skin contents. This allows the user to recognize that there are skins available for purchase, for example, when the smartphone 1 is powered on or an application is launched.

[0087] In this embodiment, the control unit 2 ends the process when purchase information 31, which is information indicating that a skin corresponding to the received skin content has been purchased, is stored in the storage unit 3. This prevents information corresponding to a skin that has already been purchased from being presented to the user again.

[0088] In this embodiment, the control unit 2 transmits music information of the music being played to the server. As a result, the control unit 2 displays skin information corresponding to the music information of the music being played, i.e., the presence or absence of a skin, on the display unit 4, so that the user can recognize the presence or absence of a skin corresponding to the music being played, which is displayed on the display unit 4.
