Hereinafter, the operation of an embodiment of the present invention will be described in detail with reference to the method of FIG. 1 and the configuration of FIG. 2.

Figure 3 shows the overall configuration of a computer network for carrying out the present invention. The server or server device 310 manages the auction through a communication network 350 such as the Internet. This server 310 is typically a computer device provided by a company hosting an online auction. The server 310 includes a database for storing auction data, that is, information on bid details, a database of products, and the like, and stores a program for general auction processing and a program for performing two-way real-time auctions. The server 310 determines a successful bidder and a successful bid price in real time while auctioning in both directions according to price information presented by buyers according to the method according to the present invention described below.

The online auction is executed through a communication network 350, such as the Internet, which is an example of a communication network, which may be a wired or wireless network, or may be a telephone network. Or it may be a mobile communication network. Hereinafter, the communication network where the auction is made will be described as the Internet.

The seller who intends to sell the product by providing the auction is connected to the server 310 through the Internet 350 using the seller terminal 200. In addition, the purchasers who want to purchase the auction goods are connected to the server 310 through the Internet using the purchaser terminal 220. The auction is carried out between the seller and the buyer via the server 310.

In FIG. 3, both the seller terminal device 200 and the purchaser terminal device 220 are computers, but this is only an example, and each terminal device 200 or 220 may be a web TV, a mobile phone, a PDA, or the like. It could be a device like a palm-top.

In addition, an apparatus 290 such as FIG. 2 according to the present invention may be included in the server 310 of FIG. 3.

A seller who wants to sell a product through an auction accesses the server 310 through the Internet 350 using the terminal device 320 and provides information about the product to be sold, the start time of the auction, and the auction starting price. Set the information (step 100). This information is stored in the auction product register 210. The information about the merchandise registered by the seller may be such as a product name, the number of merchandise, the manufacturer, the model name, the date of purchase of the product and the condition of the product. The time at which the auction is started may be arbitrarily determined by the seller or may be selected and determined by the seller at a predetermined time at the server 310. The starting price of the auction is determined by the seller, but the predetermined price is determined by the seller. If the bid is made at this predetermined price during the auction, it may be possible to bid without proceeding any further auction. It is also possible for the seller to determine the minimum bid price and automatically bid if the bid price is entered below this minimum bid price until the auction closes.

The auction product display unit 230 displays the information on the auction product stored in the auction product registration unit 210 and the information on the auction start time and proceeding time to the buyer through the terminal device 220 of the buyer to participate in the auction, the buyer The application for participation in the auction is accepted (step 110). Naturally, more detailed information about the auction item can be displayed to the buyer. You can also tell buyers how to proceed with the auction.

At this point, the auction may be in progress to determine in advance. For example, you can decide that the auction will close 30 minutes after the auction starts. In this case, just before the 30 minutes have passed, the auction product could be auctioned off by a buyer who bids at a slightly higher price than the bid price so far, which results in a loss of time for the buyer's chance to bid at a higher price. Can bring To prevent this, in step 110, the auction product display unit 230 extends the auction closing time by a predetermined time if the buyer has a new bid within a predetermined time before the auction closing time determined from the auction starting price and the auction progress time. It is also desirable to indicate information about the auction extension time. For example, if there is a new bid within three minutes before the auction closes, let the buyer know that the auction will be extended for five minutes, letting the buyer know that they have time to respond to the new bid. Naturally, these are not values, and they can be changed depending on the auction's operation. However, if the duration of the auction presented at 110 is long, these values should be relatively large. If the auction is short (for example 5 minutes), these values should be relatively small (for example 20 seconds). Would be desirable. Properly adjusting the auction run time and the extended values will have the effect of creating tension and urgency to close the auction in the same short time as the actual auction among buyers participating in the auction.

The auction start notification unit 240 notifies the buyers who have indicated their intention to participate in the auction before the auction start time (step 120). Buyers who sign up for auctions often forget about auction times if they do something else before the auction begins. Especially if the auction time is short, you will not be able to participate in the auction you applied for. To prevent this, buyers who sign up for a certain time before the auction starts will be notified that the auction will start.

To this end, in step 110, the buyer who applies for an auction participation designates a time to notify that the auction starts, and in step 120, the auction start notification unit 240 sets the buyer's terminal device at the time preset by the buyer. It is desirable to generate an acoustic signal via 220 to inform the buyer that the auction is starting. The buyer is still connected to the Internet 350, and the auction start notification unit 240 transmits a data stream to the buyer's terminal device 220 at the time set by the buyer, For example, via a sound card to inform the buyer that the auction is starting. In the terminal device 220 of the purchaser, a program capable of driving streaming data such as real audio is installed, and the program should be executed in the terminal device 220 of the buyer before the set time. Real Audio means the name of a commercial program owned by Real Audio Corporation.

As another method of notifying the buyer, the buyer who applies for the auction at step 110 designates a time for notifying that the auction starts, and at step 120, the auction start notification unit 240 sets the time previously set by the buyer. It is preferable to display the auction start screen on the screen of the buyer's terminal device 220 to inform the buyer that the auction starts. The purchaser may have connected to the server 310 by executing a web browser program, and if the user continues to access the Internet and uses his terminal device 220, the auction start notification unit 240 may purchase the purchaser at a time preset by the buyer. On the screen of the terminal device 220 of the active window that can participate in the auction or displays the active window containing the message that the auction starts.

As another method of notifying the buyer, the buyer applying for an auction at step 110 designates a time and a communication means for notifying that the auction is started, and at step 120, the auction start notification unit 240 is provided by the buyer. It is preferable to notify the buyer that the auction starts through the communication means designated by the buyer at the preset time. The means of communication specified by the purchaser may be a mobile phone, for example, or may specify an address from which to send mail. The above two methods require that the buyer to participate in the auction must always be connected to the Internet 350 or connected to the server 310 via the Internet 350, but this method requires that the buyer remain connected to the Internet. There is no.

FIG. 4 illustrates an example of a screen for designating a time and delivery method of notifying that the auction is started in step 110 to notify the buyer that the auction starts.

When the buyer selects a function for informing the start of the auction, a screen as shown in FIG. 4 appears, and when the buyer enters reference numerals 400 to 430, the contents are set in the auction product display unit 230. In the portion 400 for describing the auction identification code, the buyer enters the auction code to participate. If you select the reservation function on the screen to participate in the auction to proceed to the screen of Figure 4 will automatically enter the identification code. Once the auction code is entered, the time remaining until the auction is displayed. The buyer can directly enter the time to start the auction in the alarm box 410 or select the inverted triangle using a mouse-like means to select a preset value to specify the time to start the auction. For example, if 5 is selected and the confirmation portion 440 is selected, the auction start notification unit 240 notifies the buyer that the auction starts through a sound signal or an auction start screen 5 minutes before the auction starts. Alternatively, when notifying through a mobile phone, enter a telephone number in the reference number 420, set the time in the reference number 430, and select the confirmation part of the reference number 440, and the auction start notification unit 240 at the designated time as described above. Sends a text message indicating the start of the auction to the mobile phone listed at 420.

In addition, the auction start notification unit 240 preferably informs the seller of the auction to start. Informing the buyer of the start of the auction may use the same method as the above method.

After the auction start time, the real-time auction proceeding / management unit 250 auctions the information including the message between the seller and buyers participating in the auction in real time to the seller and buyers in progress (step 140). The real-time auction proceeding / management unit 250 transmits a message that the buyer sends to the seller, the seller sends to the buyer, or the message between the buyers in real time to provide a chat service between the people participating in the auction. This enables two-way auctions among those who participated in the auction, so that the buyer can participate in the auction while asking the seller about the product. During the auction, the seller who provided the product should not be able to bid on the product to avoid confusion.

The information transmitted to the seller and the buyer by the real-time auction proceeding / management unit 250 preferably includes information transmitted to the seller and the buyer by the server 310 as well as a message between the seller and the buyer. This is because the server 310 may also display information necessary for the seller and the buyer on the chat screen included in the auction progress screen participating in the auction.

The information transmitted to the seller and buyers by the real-time auction proceeding / management unit 250 includes information on the current bid price, the number of bids, the number of auction participants, waiters, the buyer with the highest bid price, and the time remaining until the auction closes. It is preferable to include the information to include. A waiter is someone who is looking at the auction progress window but is not participating in the auction.

In this case, the information transmitted to the seller and the buyer may preferably include information on the purchasers of a predetermined number of persons who have presented the next bid price except the highest bid price. This is because marking buyers who offered the next highest bid price in addition to the one who gave the highest bid price would be beneficial to keep the auction bid high by inducing competition in the auction.

In addition, the auction server 310 may send a message to help the buyer to proceed to the auction progress window. For example, if a bid comes in at a higher price than the current price, it is notified in the auction progress window, or if the auction close time is 30 seconds, for example, the auction progress window informs people participating in the auction. You will be able to wake up. That is, it can play a role of conducting an actual offline auction.

Reference 500 shows information about the item being auctioned, the auction status displays the current maximum bid in the current price (505) section, the auction participant (510) section displays the number of people who participated in the current auction, Waiting is indicated at 515. In reference numeral 520, the IDs, bid amounts, and bid times of two upper bidders are displayed. The number of top bidders may be increased, which will depend on the auction run. Reference numeral 525 indicates the remaining time. Reference numeral 530 shows a chat window for sending and receiving messages between auction participants. Entering a post in the conversation 535 and selecting Send 540 will enter the post into the upper chat window where it will be visible to others. Participants' IDs are shown in 545. In order to display the seller differently from the buyers, the seller was further labeled. Alternatively, the ID may be displayed in a different color inside the chat window to identify the seller. As shown in FIG. 5, the auction may be performed while inquiring the seller about the product. Reference numeral 550 indicates the current highest bid. In order to participate in the auction, the auction price is selected by selecting the '+' and '-' portions of the reference numeral 555 and the quantity 560 is selected. When the bidding price and the quantity of the product are determined and the bidding is selected (565), the bidding price is determined. To stop the auction while participating in the auction or while waiting, select Exit (570) to exit and select the reference number 575 to switch to the home page of the auction site.

The real-time auction proceeding / management unit 250 stops the bidding after the auction closing time and closes the auction by bidding the product to the buyer who presented the highest amount up to that time (step 150).

At this time, if there is a new bid within a predetermined time before the auction closing time / management unit 250 preferably extends the bid closing time by a predetermined time. When the remaining time 525 is within 3 minutes as described above, when a new bid comes in, the time display of the remaining time 525 portion is changed to 5 minutes. As mentioned above, the three or five minute units are subject to change depending on the auction conditions.

The real-time auction proceeding / management unit 250 preferably transmits and receives a message transmitted between the seller and the buyers participating in the auction on the screen of the terminal device of the seller and the buyer for a predetermined time after the auction is closed. . That is, after the auction is closed, the real-time chat screen as shown in FIG. 5 is maintained, for example, for 5 minutes to maintain a dialogue after the auction ends between the auction participants.

In addition, the real-time auction proceeding / management unit 250 preferably informs each auction participant that the auction is over and notifies the successful bidder. This may be displayed on the screen of the terminal device 220 of the successful bidder or executed through a separate e-mail.

Through such a step, the real-time auction proceeding / management unit 250 enables a real-time auction by enabling a chat while the auction is carried out between the seller and the buyer who participated in the auction. In addition, two-way communication between sellers and buyers is possible through chat, and the auction proceeds while inquiring about the product, so that the real auction can be felt.
