Description

  The present invention relates to a display system for displaying information in a mobile phone that transmits and receives information via a network. The present invention also relates to a merchandise sales system and merchandise sales method, a videophone system, and a device remote control system using the display system.

  In recent years, with the advancement of IT technology, various items can be processed by using a terminal (personal computer, mobile phone, etc.) at hand of the user via the Internet.

  For example, a product sales system called so-called online shopping or Internet shopping is used, in which product information and product delivery information are exchanged between a customer and a store using a terminal at hand of the customer, and a product ordering procedure is performed. (For example, see Patent Document 1, Patent Document 2, and Patent Document 3). In this system, a customer can access a management server of a store from a terminal at hand, start up the website, and obtain desired product information. Thus, for example, the appearance, specifications, and the like are displayed on the display of the terminal at the customer's hand, and the customer determines which product to order by looking at it. When the determined information is input to a page in the website by the customer, this information is transmitted from the terminal to the management server of the store. If the product is digital content such as music or software, the product can be downloaded to the terminal at hand of the customer immediately after this. If the product is not digital content and is a regular product that needs to be delivered to the customer, this information can also be entered by entering the product's delivery information (delivery location, specified time, etc.) on a page within the website as well. Information is transmitted and registered in the customer database of the management server. The dealer refers to this information when delivering the product and delivers the product. According to this system, the flow from when an order is placed to when it is delivered to a customer can be managed by the management server without human effort. If there are many, there are effects of reducing sales costs and reducing human error. And the biggest advantage for customers is that they can check the details of the products at the customer's hand without going to the dealership, and can go from ordering to delivery procedure at any time regardless of the opening time of the dealership. .

  At this time, a mobile phone can be used as a terminal used by the customer. In this case, the above advantages can be maximized by the feature of the mobile phone that is convenient to carry and can be accessed anytime and anywhere.

In addition to the merchandise sales system, the mobile phone is connected to a network as a terminal and used, for example, includes a videophone system (see, for example, Patent Document 4) and a device remote control system (see, for example, Patent Document 5).

  However, in any of the above applications, when a mobile phone is used as the above-described terminal, the display of the mobile phone is generally only 2 to 3 inches in size, so that the user can display the screen displayed on the display. Therefore, there is a problem that it is difficult to obtain sufficient information. For example, in the product sales system described above, since a customer is considering purchasing a product, the appearance photo is displayed by accessing the website of the store, but the product appearance photo is sufficiently detailed. It may not be displayed. In particular, when selecting one product from multiple products, if you want to select products to order by displaying candidate products side by side on the same screen and comparing them, you can identify the details on the small display of your mobile phone. It is often difficult to do. Even if the resolution of the display is sufficient, it may not be discernible with human vision unless it is enlarged. Therefore, when a mobile phone is used, there is a high possibility that a customer will order an incorrect product.

  In addition to displaying product information, a mobile phone display may be insufficient when a customer specifies a delivery location for a product. For example, in the map display on the website, when the customer specifies the delivery location by specifying the delivery location with the cursor, when the map is displayed as image information on the small display of the mobile phone, the detailed location identification is Have difficulty. Therefore, there is a high possibility that the customer designates an incorrect delivery location.

  The same problem exists not only in the merchandise sales system but also in other applications when a mobile phone is used as a terminal, for example, a videophone system or a device remote control system. That is, since the display of the mobile phone is small, it is difficult to see the screen, and the user is likely to perform an erroneous operation.

Therefore, a highly reliable device remote control system can be obtained.

  Hereinafter, the best mode for carrying out the present invention will be described.

  FIG. 1 is a diagram showing the configuration of the first embodiment when the display system of the present invention is applied to a merchandise sales system. In the figure, a customer's mobile phone 10 is connected to a sales management server 30 of a store through a network 100. The mobile phone 10 is connected to the personal computer 20 via a communication network 200 under the customer's condition. The sales management server 30 is connected to a product database 35 and a delivery database 36. Both the mobile phone 10 and the personal computer 20 have a display, and an LCD (Liquid Crystal Display) type or a CRT (Cathode Ray Tube) type is used. The size of the first display of the mobile phone 10 is 2 Usually, the size of the second display of the personal computer 20 is about 15 inches or more. The display system of the present invention uses a combination of the first display of the mobile phone 10 and the second display of the personal computer 20.

  As the network 100 for connecting the mobile phone 10 and the sales management server 30, the Internet is generally used, and for this purpose, for example, a high-speed communication line of 10 Mbps or more using a telephone line or an optical fiber is used. Therefore, the mobile phone 10 needs to have a function capable of connecting to this network.

On the other hand, the mobile phone 10 and the personal computer 20 are connected by a local network using a communication network 200. The data transfer performance required for the communication network 200 may be 1 Mbps or higher, and wireless LAN communication complying with Bluetooth, HomeRF, Wi-Fi standards, etc., and infrared communication complying with IrDA standards can be used. Therefore, the mobile phone 10 and the personal computer 20 need to have these communication functions.
When connecting the mobile phone 10 and the personal computer 20 through the communication network 200, for example, in the method described in Japanese Patent Application Laid-Open No. 2003-032261, a method using the mobile phone 10 as a master and the personal computer 20 as a slave can be used.

  The mobile phone 10 can exchange information via the sales management server 30 and the network 100. For example, when information specifying a product desired by a customer is transmitted from the mobile phone 10 to the sales management server 30, the product information can be obtained from the sales management server 30 based on the product database 35. The mobile phone 10 transmits this information to the personal computer 20 via the communication network 200. Both the mobile phone 10 and the personal computer 20 can display this information, but the first display displays, for example, character information relating to the size and material of the product as a first display screen that simply represents the information. To do. For example, an image of the appearance of a product is displayed on the second display as a second display screen that displays the information in more detail than the first display screen. Selection of these display contents may be performed by the mobile phone 10 or the personal computer 20.

  The mobile phone 10 is directly connected to the sales management server 30. The relationship between the mobile phone 10 and the personal computer 20 is such that the former is a parent device and the latter is a child device. That is, the personal computer 20 is used as the slave unit of the mobile phone 10 to perform the display. Therefore, the information transmitted from the mobile phone 10 to the personal computer 20 does not have to be all the information obtained from the sales management server 30 by the mobile phone 10, and may be only the minimum information necessary for display on the personal computer 20.

  The communication network 200 does not have to be wireless, and cable communication conforming to the USB standard can also be used.

  The same screen may be displayed on the first display and the second display. Even in this case, the customer can obtain detailed information by viewing a clearer image on the large display of the personal computer 20.

  The personal computer 20 has a display larger than that of the mobile phone 10 and can have a communication function compatible with the communication network 200. However, a notebook personal computer is preferable because it is convenient to carry. Since the customer uses the mobile phone 10 to directly access the sales management server 30 and the personal computer 20 is used only as a slave unit, the personal computer 20 has a communication function via the communication network 200 with the mobile phone 10. It is possible to use arbitrarily what is provided with. For example, a customer can borrow a personal computer for a short time and use it. At this time, since only the mobile phone 10 is connected to the Internet, the cost required for the Internet connection is imposed only on the mobile phone 10. Further, since the personal computer 20 is used only as a slave unit of the mobile phone 10, information when the customer accesses the sales management server 30 does not unnecessarily remain in the personal computer 20. Accordingly, even if another person's personal computer is borrowed as the personal computer 20, personal information of the customer does not unnecessarily remain on the personal computer 20, so there are few security problems even if another person's personal computer is borrowed and used as the personal computer 20. . As described above, the personal computer 20 described above mainly uses the display function as a display device. Therefore, instead of this, it is possible to connect to the mobile phone 10 through the communication network 200, and it is possible to use a TV or a car navigation device having a display larger than that of the mobile phone, and it can be used similarly as a display device.

  The process flow of the merchandise sales system according to the first embodiment of the present invention will be described below. FIG. 2 is a flowchart showing the processing flow.

  The customer connects the mobile phone 10 to the personal computer 20 through the communication network 200 (S11). Next, the mobile phone 10 is connected to the sales management server 30 via the network 100 (S12). Next, the mobile phone 10 requests the sales management server 30 for sales product information, which is information about the desired product (S13). This is done, for example, by accessing the website opened by the store with the mobile phone 10 and entering the desired product name in the page. Sales merchandise information is information including the appearance, specifications, prices, etc. relating to merchandise that the customer wishes to purchase. Here, the desired product does not have to be one, and information on all of the plurality of products that are candidates for purchase can be requested as one piece of sales product information.

  Based on the product database 35, the sales management server 30 transmits the sales product information to the mobile phone 10 via the Internet (S31).

After receiving the sales merchandise information, the mobile phone 10 passes through the communication network 200.
This is transmitted to the personal computer 20 (S14).

  The mobile phone 10 displays the first sales product screen on the first display of the mobile phone 10 based on the sales product information (S15). This screen shows product information in a simplified manner. For example, the name and price of the product are shown in characters.

  The personal computer 20 displays the second sales merchandise screen on the second display of the personal computer 20 (S41). This screen shows product information in more detail than the first sales product screen. For example, this screen shows an appearance photograph of the product as an image.

  When the sales product information includes only one product information, the customer determines whether to select the product and place an order or to continue to check other products based on the first and second sales product screens. To do. In addition, when the sales product information includes information on a plurality of products, which product is selected and ordered based on the first and second sales product screens, or other items not included in this It is determined whether to continue to check the product (S16).

  When examining other products, the sales management server 30 requests the sales product information of other products from the mobile phone 10 in the same manner as described above (S13), and after receiving new sales product information, the same as described above. The information is displayed on the screen, and the procedure is repeated until the customer determines the product to order.

  When the product to be ordered is determined, the customer transmits order information specifying the name and specification of the product to be ordered from the mobile phone 10 to the sales management server 30 (S17). This is done, for example, by inputting the order information on a page different from the case where the sales merchandise information in the website is requested. Further, for example, on the screen of the mobile phone 10 or the personal computer 20, the order information is confirmed by moving the cursor to a location where the name or specification of the product is displayed and clicking, and the order information is transmitted by the customer's key operation. It may be set. After receiving the order information, the sales management server 30 registers it in the connected delivery database 36 (S32).

  Next, the sales management server 30 transmits to the mobile phone 10 information for the customer to specify the delivery location of the product (for example, map information) and product delivery information that is information including the time at which delivery is possible (S33). ).

  After receiving the merchandise delivery information, the cellular phone 10 transmits it to the personal computer 20 via the communication network 200 (S18).

  The mobile phone 10 displays the first product delivery screen on the first display of the mobile phone 10 (S19). In this screen, the place where the product can be delivered and the delivery time are indicated by characters. For example, the customer's address is indicated by characters.

  The personal computer 20 displays the second product delivery screen on the second display of the personal computer 20 (S42). This screen is a detailed representation of the location and time at which the product can be delivered in characters and images. For example, a map image near the customer's address, and the date and time at which the product can be delivered are shown in a table.

  After determining the delivery location and time after viewing the above display, the customer transmits product delivery designation information, which is information for designating the delivery location and time, from the mobile phone 10 to the sales management server 30 (S20). ). This is done, for example, by inputting a delivery location and time on a delivery specification information transmission page in the website. Further, for example, on the map screen displayed on the screen of the personal computer 20, the delivery location may be determined by moving the cursor to a location indicating the delivery location and clicking the desired location. When the customer selects and clicks the delivery designation information, the delivery designation information may be confirmed, and the delivery designation information may be transmitted by the customer's key operation. The sales management server 30 registers this information in the connected delivery database 36 (S34).

  In the processing flow shown in FIG. 2, if there is one request for sales product information once, the sales product information is transmitted only once, but actually, the sales product information is transmitted multiple times. Also good. Further, it is possible to request sales product information for each product in a plurality of times, and it is also possible to send the sales product information a plurality of times accordingly. In fact, on the first and second sales merchandise screens, the customer selects and clicks on one of the displayed items, and the sales merchandise information is requested, and the sales including detailed information about the item is requested. The product information may be transmitted from the sales management server 30 to the mobile phone 10. The request and transmission of the merchandise delivery information may be performed multiple times in the same manner.

  The sales product information is transmitted from the mobile phone 10 to the personal computer 20, but it is not necessary to transmit all of the sales product information received by the mobile phone 10 from the sales management server 30 at that time. Only information necessary for displaying the product screen may be transmitted. This is particularly effective when it takes time to transmit because the data transfer rate of the communication network 200 is not sufficient. In FIG. 2, the sales product information is transmitted to the personal computer 20 only once. However, only necessary information is transmitted a plurality of times according to, for example, switching of the second sales product screen display. May be. The product delivery information from the mobile phone 10 to the personal computer 20 may be transmitted a plurality of times in the same manner.

  In FIG. 2, the case where information is transmitted from the personal computer 20 to the mobile phone 10 is not described. For example, in the second sale product screen or the second product delivery screen, the customer moves the product or delivery with the cursor. You can specify items about the contents of. In this case, the personal computer 20 can transmit the information designated here to the mobile phone 10.

  In the embodiment described above, both the display of the sales product information and the display of the product delivery information are performed using the display system of the present invention, but only one of these information is displayed. It is also possible to use the display system of the present invention. For example, if the customer's address and the delivery date / time are simply input from the screen of the mobile phone 10 as the product delivery information, the display of the second product delivery screen is unnecessary, and the personal computer 20 is not necessary in this step. In addition, when the product name and specifications of the product are determined in advance and the customer does not need detailed information on the product, the display of the second product delivery screen (S42) is unnecessary, and the personal computer 20 is not required at this step. It is.

  In the present embodiment described above, the customer can easily select a product, place an order, and specify delivery using the display system of the present invention using the first and second displays. In particular, for items that require detailed image information, the large display of the personal computer 20 can be used, so that the possibility of a customer making an incorrect designation is reduced.

  The first and second sales merchandise screens in the present embodiment will be described in more detail with specific examples. First, as a first example, the flow from the sales merchandise information request to the order information registration in FIG. 2 when a customer purchases a bag using the merchandise sales system will be described.

  The customer requests the sales management server 30 for the sales product information regarding the product “bag” from the mobile phone 10 (S13).

The sales merchandise information transmitted as a result includes, for example, information on four types of bags (product names A to D). At this time, as shown in FIG. 3A, on the first sales merchandise screen (S15), the product names and prices of A, B, C, and D are displayed in characters. On the other hand, as shown in FIG. 3 (b), appearance pictures of A, B, C, and D are displayed side by side on the second sales merchandise screen (S41). Thereby, these can be compared on the same screen. In particular, when the customer decides to see bag A in detail, as shown in FIG. 3 (c), by selecting and clicking A on the first sales merchandise screen, as shown in FIG. 3 (d). In addition, the second sales merchandise screen displays only the bag A in an enlarged manner and also displays its detailed specifications.

By looking at this, the customer can judge by looking at the combination of shirt and pants. Also in this example, the first sales merchandise screen is displayed on a small display having a size of about 2.5 inches of the mobile phone 10, but the above character information can be sufficiently identified. On the other hand, since the 2nd sale merchandise screen is displayed on the big display which personal computer 20 has, the fine parts of each shirt and each pants and the appearance in the form which combined these can be seen in detail.

  The shirt and trousers ordered by the customer are determined as described above, and the order information is transmitted from the mobile phone 10 in the same manner as in the first example (S17).

  As a third example, a case will be described in which the customer specifies the delivery place and time and transmits the product delivery designation information (S20) after receiving the product delivery information by the product sales system.

  In this case, the sales management server 30 that has received the order information receives the information (for example, map information) for the customer to specify the delivery location of the product and the product delivery information, which is information including the deliverable time. (S33). This merchandise delivery information includes map information around the customer's address. On the first product delivery screen (S19), first, as shown in FIG. 5A, a “delivery location designation screen” and a “delivery date designation screen” can be selected. When the delivery location designation screen is selected here, the customer selects the delivery location address, and for example, as shown in FIG. 5B, “Oita Prefecture” and “Usa City” are displayed. On the other hand, on the second merchandise delivery screen, an entire map of Oita Prefecture is displayed correspondingly, as shown in FIG. 5C, and Usa City is highlighted and displayed (S42). . Further, when the AB product CD address is designated on the first product delivery screen as shown in FIG. 5D, the second product delivery screen displays “AB town CD in Usa City, Oita Prefecture, as shown in FIG. 5E.
