[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment)

[0013] Fig. 1 is a diagram showing a first embodiment of an information processing system of the present invention. As shown in Fig. 1, the information processing system in this embodiment includes an information processing device 100, a plurality of user devices 200-1 to 200-m (m is a natural number), and a server 300, which are connected to each other via a communication network 400 so as to be able to communicate with each other.

[0014] The server 300 is a communication device constituting a system or site that presents a trading price of an object. Here, the object may be, for example, a card used in a competitive trading card game, clothing, shoes, a watch, an accessory, a car, or the like that a user may possess as an item (not limited to a tangible object). The server 300 determines a trading price indicating the value of the object, and stores the determined trading price as value information. The value information stored by the server 300 is a trading price of the object that changes over time. The server 300 stores the value information for each object identification information for identifying the object. The server 300 may be provided with a database accessible from the outside, and may store the object identification information and the value information in association with each other in the database.

[0015] The information processing device 100 is a device managed by a person who operates this information processing system. FIG. 2 is a diagram showing an example of components included in the information processing device 100 shown in FIG. 1. As shown in FIG. 2, the information processing device 100 shown in FIG. 1 has a communication unit 110, a reception unit 120, an acquisition unit 130, a calculation unit 140, and an output unit 150. Note that, among the components included in the information processing device 100 shown in FIG. 1, FIG. 2 shows only the main components related to this embodiment. Note that the information processing device 100 may be provided with an authentication function for authenticating a user. The information processing device 100 provided with the authentication function may authenticate a user, for example, by using a user ID and a password input and transmitted to the user devices 200-1 to 200-m.

[0016] Communication unit 110 communicates with each of user devices 200-1 to 200-m and server 300 via communication network 400. The communication standard by which communication unit 110 communicates with each of user devices 200-1 to 200-m and server 300 via communication network 400 is not particularly specified as long as they can communicate with each other.

[0017] The reception unit 120 receives, via the communication unit 110, user identification information for identifying a user, object identification information for identifying an object designated by the user, and quantity information indicating the quantity of the objects. The user identification information, object identification information, and quantity information indicating the quantity are information input to and transmitted from the user devices 200-1 to 200-m. The user identification information is information input by a user when using this system, and may be, for example, the above-mentioned user ID. The object identification information is identification information given to an object selected from a selection of multiple objects displayed on the user devices 200-1 to 200-m. The reception unit 120 outputs the received object identification information and quantity information to the acquisition unit 130. In addition, accepting unit 120 transmits a signal prompting input of user identification information, object identification information, and quantity information to user devices 200-1 to 200-m via communication unit 110, and accepts the user identification information, object identification information, and quantity information input to user devices 200-1 to 200-m and transmitted in response to the transmitted information.

[0018] The acquisition unit 130 acquires value information corresponding to the object identification information output from the reception unit 120 from the server 300. When the object identification information and the value information are stored in association with each other in the database of the server 300, the acquisition unit 130 acquires the value information associated with the object identification information from the server 300 using the object identification information output from the reception unit 120 as a search key. The acquisition unit 130 outputs the acquired value information to the calculation unit 140. The timing at which the acquisition unit 130 acquires the value information from the server 300 may be when the reception unit 120 accepts the object identification information, or may be at regular intervals after the reception unit 120 accepts the object identification information. The regular intervals may be preset intervals so as not to place an excessive load on the server 300.

[0019] The calculation unit 140 calculates the total value of the objects to which the object identification information is assigned, for each user to whom the user identification information is assigned, based on the value information output from the acquisition unit 130 and the quantity information output from the acceptance unit 120. When the acquisition unit 130 periodically acquires value information from the server 300, the calculation unit 140 may calculate the total value of the objects to which the object identification information is assigned, using an average value of the value (market price) per unit period of the value information acquired by the acquisition unit 130. The calculation unit 140 outputs total value information indicating the calculated total value to the output unit 150.

[0020] The output unit 150 outputs the total value information indicating the total value output from the calculation unit 140. At this time, the output unit 150 may display the total value information indicating the total value output from the calculation unit 140 on a display unit (display unit 220 shown in FIG. 4) included in the information processing device 100 together with the value information acquired by the acquisition unit 130 and the quantity information accepted by the acceptance unit 120. The output unit 150 may also output the total value information indicating the total value output from the calculation unit 140 together with the user identification information. The output unit 150 may also transmit the total value information indicating the total value output from the calculation unit 140 to the user device that has transmitted the user identification information via the communication unit 110. At this time, the output unit 150 transmits a signal for displaying the total value information indicating the total value output from the calculation unit 140 on the user devices 200-1 to 200-m to the user device that has transmitted the user identification information via the communication unit 110.

[0021] The user devices 200-1 to 200-m are communication devices owned and operated by users who use this information processing system. The user devices 200-1 to 200-m are equipped with an information display function, an input function, and a communication function. The display function and the input function equipped in the user devices 200-1 to 200-m may constitute a touch panel function. The user devices 200-1 to 200-m may be, for example, fixed terminals such as PCs (Personal Computers), or mobile terminals such as smartphones and tablet terminals. FIG. 3 is a diagram showing an example of components equipped in the user device 200-1 shown in FIG. 1. As shown in FIG. 3, the user device 200-1 shown in FIG. 1 has a communication unit 210, a display unit 220, an input unit 230, and a control unit 240. Note that FIG. 3 shows only the main components related to this embodiment among the components equipped in the user device 200-1 shown in FIG. 1. 3. Moreover, the user devices 200-2 to 200-m shown in FIG. 1 also include the components shown in FIG.

[0022] The communication unit 210 communicates with the information processing device 100 via the communication network 400. The communication standard by which the communication unit 210 communicates with the information processing device 100 via the communication network 400 is not particularly specified as long as they can communicate with each other.

[0023] The display unit 220 is a display that displays information. Based on a signal transmitted from the information processing device 100, the display unit 220 displays a screen for the user operating the user device 200-1 to input user identification information, object identification information, and the quantity thereof. At this time, the display unit 220 may display an image that can identify the object indicated by the object identification information in a selectable manner. A specific example of this display mode will be described later. In addition, the screen for inputting user identification information displayed by the display unit 220 may be the same as a screen for inputting a general user ID.

[0024] The input unit 230 inputs user identification information, object identification information, and the quantity thereof based on an operation from a user operating the user device 200-1. The input unit 230 inputs information based on an operation from the user in accordance with the display on the display unit 220. When the display unit 220 displays an image capable of identifying the object indicated by the object identification information in a selectable manner, the input unit 230 inputs object identification information corresponding to an image selected from the images displayed by the display unit 220.

[0025] The control unit 240 controls the communication unit 210, the display unit 220, and the input unit 230. The control unit 240 may be a CPU (Central Processing Unit) that executes an installed computer program (hereinafter, referred to as a program).

[0026] FIG. 4 is a diagram showing an example of an input screen displayed by the user device 200-1 based on a signal that prompts the user device 200-1 to input object identification information and quantity information transmitted by the reception unit 120 shown in FIG. 2 to the user device 200-1. Here, a case where the object is a card is taken as an example. As shown in FIG. 4, the display unit 220 of the user device 200-1 displays a screen that allows the user to select (input) the type of card and its quantity. In the example shown in FIG. 4, the display unit 220 of the user device 200-1 also displays the value (price) according to the quantity input for each selected card. The object identification information of the object selected according to this display and the quantity information indicating the input quantity are transmitted to the information processing device 100. The display of the object type may be an image such as a thumbnail indicating each object, or may be object identification information, or may be any display that allows the user to identify the object. When the user selects the displayed image of the object type by tapping, etc., the desired type of object is selected. Furthermore, the display for inputting the quantity may be a display for directly inputting a numerical value, or may be a display such as "+" for increasing the quantity to be input and "-" for decreasing the quantity to be input, as shown in FIG. 4.

[0027] Fig. 5 is a diagram showing an example of a screen on which the user device 200-1 displays the total value information transmitted by the output unit 150 shown in Fig. 2 via the communication unit 110. As shown in Fig. 5, the calculation unit 140 calculates the total value information for the user operating the user device 200-1, and the display unit 220 of the user device 200-1 displays the total value information transmitted via the communication unit 110 as total assets. As shown in Fig. 5, the display unit 220 of the user device 200-1 may display a user ID, which is user identification information, together with the total value information. In addition, the display unit 220 of the user device 200-1 may display objects specified by the user and their quantity together with the total value information.

[0028] The following describes an information processing method in the information processing device 100 shown in Fig. 1. Fig. 6 is a flowchart for explaining an example of the information processing method in the information processing device 100 shown in Fig. 1. Here, the processing when a user operates the user device 200-1 is described as an example.

[0029] First, the reception unit 120 receives user identification information for identifying a user via the communication unit 110 (step S1). For example, as described above, a user who uses this system may connect to a specific site using the user device 200-1, and the reception unit 120 may receive as user identification information a user ID that is input and transmitted according to a login screen displayed on the user device 200-1. Then, the reception unit 120 transmits information for displaying a screen for inputting object identification information and its quantity to the user device 200-1 that transmitted the user identification information (step S2). This screen may be a display screen that allows input (selection) of objects and their quantities as shown in FIG. 4.

[0030] When a user inputs (selects) an object and its quantity according to a screen displayed on the display unit 220 of the user device 200-1, object identification information indicating the selected object and quantity information indicating the input quantity are associated with each other and transmitted from the user device 200-1 to the information processing device 100. When the reception unit 120 receives the transmitted object identification information and quantity information via the communication unit 110 (step S3), the acquisition unit 130 acquires value information indicating the current market value of the object indicated by the object identification information from the server 300 (step S4). The specific method by which the acquisition unit 130 acquires the value information may be the method described above. When the reception unit 120 accepts multiple object identification information for one user identification information, the acquisition unit 130 acquires value information indicating the market value of each of the objects indicated by the multiple object identification information received from the server 300.

[0031] Next, calculation unit 140 calculates the total value of the objects to which the object identification information is assigned, for each user to whom the user identification information is assigned, based on the value information acquired by acquisition unit 130 and the quantity information accepted by acceptance unit 120 (step S5). When acceptance unit 120 accepts multiple object identification information and quantity information for one user identification information, calculation unit 140 multiplies the value of the object indicated by each object identification information accepted by acceptance unit 120 by the quantity, and adds them up for each user identification information to calculate the total value of all the objects specified by the user indicated by the user identification information.

[0032] Then, the output unit 150 transmits total value information indicating the total value calculated by the calculation unit 140 to the user device 200-1 via the communication unit 110 (step S6). The display unit 220 of the user device 200-1 displays the transmitted total value information as total assets. The display mode may be as shown in FIG. 5.

[0033] In this way, in this embodiment, market price information for the object specified by the user is obtained from an external source, and the total value is calculated and presented for each user. This allows the user to easily grasp the total market price of the objects specified by the user. (Second embodiment)

[0034] FIG. 7 is a diagram showing a second embodiment of the information processing system of the present invention. As shown in FIG. 7, the information processing system in this embodiment includes an information processing device 101, a plurality of user devices 200-1 to 200-m, and servers 301-1 to 301-n (n is a natural number) connected to each other via a communication network 400 so as to be able to communicate with each other. The information processing device 101 is a device managed by a person who operates this information processing system. The user devices 200-1 to 200-m are the same as those in the first embodiment. Each of the servers 301-1 to 301-n is a communication device constituting a system or site that presents a trading price of the object handled in the first embodiment. The servers 301-1 to 301-n constitute different systems or sites, and the trading price of each object is determined in each system or site. Each of the servers 301-1 to 301-n stores a trading price indicating the value of the object as value information. The value information stored in each of servers 301-1 to 301-n is a trading price of the object that changes over time. The value information stored in each of servers 301-1 to 301-n may be different from each other, or may be the same as each other. Servers 301-1 to 301-n store value information for each object identification information for identifying the object. Servers 301-1 to 301-n may be provided with a database accessible from the outside, and may store object identification information and value information in association with each other in the database.

[0035] FIG. 8 is a diagram showing an example of components included in the information processing device 101 shown in FIG. 7. As shown in FIG. 8, the information processing device 101 shown in FIG. 7 has a communication unit 110, a reception unit 120, an acquisition unit 131, a calculation unit 141, and an output unit 150. Note that, among the components included in the information processing device 101 shown in FIG. 7, FIG. 8 shows only the main components related to this embodiment. Note that the information processing device 101 may have an authentication function for authenticating a user. The information processing device 101 having the authentication function may authenticate a user, for example, by using a user ID and a password input to and transmitted from the user devices 200-1 to 200-m. Each of the communication unit 110, the reception unit 120, and the output unit 150 is the same as that in the first embodiment.

[0036] The acquisition unit 131 acquires value information corresponding to the object identification information output from the reception unit 120 from each of the servers 301-1 to 300-n. When the object identification information and the value information value are stored in association with each other in the database of the servers 301-1 to 300-n, the acquisition unit 131 acquires the value information associated with the object identification information from each of the servers 301-1 to 300-n using the object identification information output from the reception unit 120 as a search key. The acquisition unit 131 outputs the acquired multiple pieces of value information to the calculation unit 141. The timing at which the acquisition unit 131 acquires the value information from each of the servers 301-1 to 300-n may be when the reception unit 120 accepts the object identification information, or may be at regular intervals after the reception unit 120 accepts the object identification information. The regular intervals may be preset intervals so as not to place an excessive load on the server 300.

[0037] The calculation unit 141 calculates the total value of the objects to which the object identification information is assigned for each user to which the user identification information is assigned, based on the multiple pieces of value information output from the acquisition unit 131 and the quantitative information output from the acceptance unit 120. At this time, the calculation unit 141 may calculate the total value by multiplying a value obtained by averaging the multiple pieces of value information output from the acquisition unit 131 by the number of servers 301-1 to 300-n (a value obtained by dividing the sum of the multiple pieces of value information output from the acquisition unit 131 by n). Furthermore, when calculating the average value, the calculation unit 141 may multiply the value indicated by each of the multiple pieces of value information output from the acquisition unit 131 by a weighting coefficient previously assigned to each of the servers 301-1 to 300-n, and multiply the result by the quantitative information to calculate the total value. Furthermore, similarly to the acquiring unit 130 in the first embodiment, when the acquiring unit 131 periodically acquires value information from each of 301-1 to 300-n, the calculating unit 141 may calculate the total value of the objects to which the object identification information is assigned, by using an average value of the value (market price) per unit period of the value information acquired by the acquiring unit 130. The calculating unit 141 outputs the total value information indicating the calculated total value to the output unit 151.

[0038] The following describes an information processing method in the information processing device 101 shown in Fig. 7. Fig. 9 is a flowchart for explaining an example of the information processing method in the information processing device 101 shown in Fig. 7. Here, the description takes as an example the processing performed when a user operates the user device 200-1.

[0039] First, the reception unit 120 receives user identification information for identifying a user via the communication unit 110 (step S11). For example, as described above, a user who uses this system may connect to a specific site using the user device 200-1, and the reception unit 120 may receive as user identification information a user ID that is input and transmitted according to a login screen displayed on the user device 200-1. Then, the reception unit 120 transmits information for displaying a screen for inputting object identification information and its quantity to the user device 200-1 that transmitted the user identification information (step S12). This screen may be a display screen that allows input (selection) of an object and its quantity as shown in FIG. 4.

[0040] When the user inputs (selects) an object and its quantity according to the screen displayed on the display unit 220 of the user device 200-1, object identification information indicating the selected object and quantity information indicating the input quantity are associated with each other and transmitted from the user device 200-1 to the information processing device 101. When the reception unit 120 receives the transmitted object identification information and quantity information via the communication unit 110 (step S13), the acquisition unit 131 acquires value information indicating the current market value of the object indicated by the object identification information from each of the multiple servers 301-1 to 301-n (step S14). The specific method of the acquisition unit 131 acquiring the value information may be the method described above. When the reception unit 120 receives multiple object identification information for one user identification information, the acquisition unit 131 acquires value information indicating the market value of each of the objects indicated by the multiple object identification information received from each of the multiple servers 301-1 to 301-n.

[0041] Next, the calculation unit 141 calculates the total value of the objects to which the object identification information is assigned for each user to whom the user identification information is assigned, based on the average value of the multiple pieces of value information acquired by the acquisition unit 131 from each of the multiple servers 301-1 to 301-n and the quantity information accepted by the acceptance unit 120 (step S15). When the acceptance unit 120 accepts multiple pieces of object identification information and quantity information for one user identification information, the calculation unit 141 multiplies the average value of the multiple pieces of value information acquired by the acquisition unit 131 from each of the multiple servers 301-1 to 301-n for each piece of object identification information accepted by the acceptance unit 120 by the quantity, and sums them up for each user identification information to calculate the total value of all objects designated by the user indicated by the user identification information.

[0042] Then, the output unit 150 transmits total value information indicating the total value calculated by the calculation unit 141 to the user device 200-1 via the communication unit 110 (step S16). The display unit 220 of the user device 200-1 displays the transmitted total value information as total assets. The display mode may be as shown in FIG. 5.

[0043] In this manner, in this embodiment, market price information for an object designated by a user is obtained from an external source, and a total value is calculated and presented for each user. This allows the total market price of the objects designated by the user to be easily understood. Furthermore, market prices are obtained from multiple systems and sites, and the average value or a market price value according to the weighting of the systems and sites is used. This allows the total assets to be understood based on a more accurate market price.

[0044] Although the above description has been given by allocating each function (processing) to each component, this allocation is not limited to the above. In addition, the configuration of the components is also not limited to the above-mentioned forms, which are merely examples. In addition, each embodiment may be combined.

[0045] Note that the user may operate the information processing device 100 instead of operating the user devices 200-1 to 200-m. In this case, the output unit 150 may have an information display function, and the output unit 150 may display a screen (for example, the screen shown in FIG. 4) that prompts the user to input information, and the reception unit 120 may receive the input of information in response to the user's operation on the display screen displayed by the output unit 150.

[0046] The processes performed by each of the above-mentioned components may be performed by logic circuits that are created according to the purpose. Also, a program in which the process contents are described as a procedure may be recorded on a recording medium that can be read by each of the information processing devices 100 and 101, and the program recorded on the recording medium may be read and executed by each of the information processing devices 100 and 101. The recording medium that can be read by each of the information processing devices 100 and 101 refers to a removable recording medium such as a floppy (registered trademark) disk, a magneto-optical disk, a DVD (Digital Versatile Disc), a CD (Compact Disc), a Blu-ray (registered trademark) Disc, a USB (Universal Serial Bus) memory, and an SD card, as well as a memory such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a HDD (Hard Disc Drive) that are built into each of the information processing devices 100 and 101. The program recorded on the recording medium is read by a CPU provided in each of the information processing devices 100 and 101, and the same process as that described above is performed under the control of the CPU. Here, the CPU operates as a computer that executes a program read from a recording medium on which the program is recorded.
