Description

The present invention provides information regarding the route to be used for shopping by a shopper in a store such as a department store or a supermarket (referred to as “shopping center” in this specification). It relates to the in-house guidance system provided.

  Shopping centers have grown in size in recent years, and it is difficult to find where the products you want to purchase are. In such a case, we look at the information boards installed at the entrance and near the escalator, and ask people at the information counter. However, when it is desired to purchase a plurality of products, it is often desirable to know not only the location of the product but also what route should be used to move through the hall to purchase the product.

  In order to solve such problems, Patent Documents 1 to 5 listed below disclose a system for displaying and guiding a route from the current position of a shopper to a purchase place of a product.

  By using each of the above-described inventions, a shopper can obtain a route to a product he / she wants to purchase. However, when shopping at a shopping center, for example, if he / she purchases a heavy product first, he / she must walk through the hall with the heavy product. In addition, if you buy warm or cold foods first, they may be consumed when you leave the shopping center, or on the contrary. In other words, when setting a route at a shopping center, it is necessary not only to set the route but also to set the route reflecting the product attribute and the priority of the shopper. They are not considered at all.

  Therefore, the present inventor invented an in-house guidance system that guides a route that takes into account the product attributes and the priority of the shopper for the product when guiding the route for purchasing the product to the shopper at the shopping center. .

  The invention of claim 1 is an in-house guidance system that provides shoppers with information about routes in a shopping center, wherein the in-house guidance system is at least one of the weight, size, and temperature of a product.

Ranking each product based on one or more product attributes, assigning points corresponding to the ranking, and adding the points assigned for each product attribute for each product to calculate the points for the product Based on the point calculation unit, the order of movement in each area is determined based on the calculated point, map information for storing the route in each area in the map information storage unit in the hall, and the arrangement position of the product And a route setting unit for setting a route for the shopper to purchase a product by determining the order of movement of each area based on a predetermined condition, and the set And an output unit that outputs a route.

  By configuring as in the present invention, it is possible to set a route taking into account product attributes, instead of simply providing information related to a route in a shopping center as in the prior art.

  In the invention of claim 2, the product attribute storage unit further includes a distance as the product attribute, and the point calculation unit preliminarily stores the product based on information on an arrangement position in the acquired product attribute. Classify each defined area, rank each product based on at least one product attribute among the weight, size, temperature, and distance in each area, and give points corresponding to that ranking And it is the hall guidance system which calculates the point with respect to this goods by adding the point provided for every goods attribute for every goods.

  As in the present invention, it is preferable to consider the distance as a product attribute.

  In the invention of claim 3, the in-house guidance system further includes a priority input receiving unit that receives at least one input of information indicating which of the weight, size, and temperature has priority. The point calculation unit performs a point calculation process for adding or multiplying a predetermined coefficient to the product attribute received by the priority input reception unit for the points given for each product attribute, and thereafter This is a hall guidance system that calculates points for a product by adding points for each product attribute.

  By configuring as in the present invention, it is possible to set a route in consideration of conditions preferential to shoppers and product attributes.

  In the invention according to claim 4, the in-house guidance system further moves in each area by sorting the points for each product calculated by the point calculation unit according to a predetermined condition for each product for each area. It is an in-house guidance system having a sorting unit for determining the order to perform.

  As in the present invention, the order of movement in the area is determined by sorting the points according to a predetermined condition.

  In the invention of claim 5, in the point calculation unit, the predetermined area is an in-house guidance system that is performed by receiving an input from the shopper.

  In the invention of claim 6, in the route setting unit, the order of movement of each area is an in-building guidance system that is performed by receiving an input from the shopper.

  As in these inventions, the shopper may specify the area range and the order of movement between the areas.

  In the invention of claim 7, the output unit is an in-building guidance system that further transmits an e-mail attached with the set route to an e-mail address that has received registration from the shopper.

  By configuring in this way, the shopper can browse information on the route on the mobile terminal used by the shopper.

  The invention according to claim 8, wherein the priority input receiving unit receives an input of ranking of one or more priorities among weight, size, and temperature among the product attributes, and in the point calculation unit The in-building guidance system performs an arithmetic processing of points for adding or multiplying a predetermined coefficient of the product attribute based on the priority of the product attribute received by the priority input receiving unit.

  As in the present invention, ranking may be performed regarding which of product attributes is important.

  The invention according to claim 9, wherein the selected product input receiving unit further receives an input indicating that the product is scheduled to be purchased in the last or second half of the products scheduled to be purchased, and the point calculating unit. In the in-house information system, a point calculation process for adding or multiplying a predetermined superior selection coefficient is performed for the product for which the designation has been received.

  By configuring in this way, points can be intentionally changed for the product purchased in the last or second half, so that it is possible to set a route in accordance with the designation from the shopper.

According to the present invention, when a shopping center is guided to a shopper at a shopping center, an in-building guidance system is provided that guides a route that takes into account the product attributes and the priority of the shopper.

  FIG. 1 shows an overall conceptual diagram of the hall guidance system 1 of the present invention, and FIG. 2 shows an example of the system configuration. The in-house guidance system 1 has one or more installation terminals that accept input of products desired to be purchased from shoppers and one or more servers that execute processing such as route setting based on the input information. However, all processing may be executed by a single computer terminal (or server).

  The server or installation terminal that implements the in-house guidance system 1 includes an arithmetic device such as a CPU that executes arithmetic processing of a program, a storage device such as a RAM and a hard disk that stores information, and processing results and storage devices of the arithmetic device. It has at least a communication device that transmits and receives information to be stored via a network such as the Internet or a LAN. Each function (each unit) realized on the terminal is executed when a means (program, module, etc.) for executing the process is read into the arithmetic device. When each means uses the information stored in the storage device in the processing, each means reads out the corresponding information from the storage device, and uses the read information for processing in the arithmetic device as appropriate. The server may include an input device such as a keyboard and a mouse and a display device such as a display.

  Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area. Various storage formats can be used in the storage unit, and arbitrary formats such as a database and a data file can be used.

  The installation terminal may be installed at, for example, an entrance / exit of a shopping center or a reception (information counter).

  The in-house guidance system 1 includes a selected product input reception unit 2, a priority input reception unit 3, a product attribute acquisition unit 4, a product attribute storage unit 5, a point calculation unit 6, a sort unit 7, a route setting unit 8, and a building map information storage. Part 9 and output part 10.

  The selected product input accepting unit 2 accepts identification information (information identifying a product such as a product name and product ID) of the selected product by selecting a product that the shopper wants to purchase with an installation terminal or the like.

  In the priority input receiving unit 3, the shopper inputs on the installation terminal which product attribute has priority regarding the weight, size, temperature, and distance from the doorway, and receives the input. Here, the weight is the weight of the product, the size is the size or volume of the product, and the temperature is the temperature of the product (freezing (eg, less than 0 ° C.), warm (eg, 25 ° C. or more), refrigerated (eg, 0 ° C.) The distance is a distance from a predetermined point (the origin of the area), and when the temperature is selected as the priority, the temperature is frozen. You may also accept input by selecting whether to prioritize the product or the product with a warm temperature, that is, if priority is given to frozen products, the order is (frozen, warm, refrigerated, normal temperature). If warm products are given priority, they are ranked in the order (warm, frozen, refrigerated, room temperature).

  The product attribute acquisition unit 4 acquires the attributes (weight, size, temperature, distance) of the corresponding product from the product attribute storage unit 5 based on the product identification information received by the selected product input reception unit 2.

  The product attribute storage unit 5 stores product attributes of products handled at the shopping center. A conceptual diagram of the product attribute storage unit 5 is shown in FIG. As described above, the product attributes include weight, size, temperature, distance, and product placement position.

  The point calculation unit 6 ranks each product acquired from the product attribute storage unit 5 by the product attribute acquisition unit 4 for each area where the product is arranged and for each product attribute of the product. Based on the given points, the points of each product are calculated. In calculating the points, for the high priority attribute received by the priority input receiving unit 3, a point for the attribute of the product is calculated after adding or multiplying a predetermined coefficient to the point.

  The sorting unit 7 sorts the products calculated by the point calculation unit 6 in order from a product with a high point (or a product with a low point) for each predetermined area. The predetermined area refers to an area obtained by dividing a shopping center into one or more areas in advance. For example, it corresponds to a floor or a partition of a store. The area may be set by receiving an input from a shopper in addition to being classified in advance.

  Since products with high points are products that are calculated to be purchased before products with low points, the sorting unit 7 is configured to sort products with high points in order. When the points are given so that it is better to purchase before the product with higher points, the sorting unit 7 can be configured to rearrange the products with the lower points in order. That is, for each area, rearrangement may be performed in the order in which the products are purchased based on the points given to the products. In this specification, “sorting” and “sorting” refer to general processing in which the order is changed by using, for example, a pointer without actually performing the process of changing the order. included.

  The route setting unit 8 performs route setting on the products sorted for each area based on the map information in the hall stored in the hall map information storage unit 9. In addition, after setting the route for each area, the route setting for the order of movement in the area is performed. The order of moving the areas may be set in advance (for example, in order from the top, in order from the bottom), or by receiving the input of the shopper, the order in which the areas are moved may be set accordingly. .

  The in-house map information storage unit 9 stores in-house map information of the shopping center, and stores which shelves are located in the in-house.

  The output unit 10 outputs the travel route of the shopper performed by the route setting unit 8 via a printer or a screen.

  Next, an example of the processing process of the hall guidance system 1 of the present invention will be described with reference to the flowchart of FIG. 3 and the conceptual diagrams of FIGS. In this embodiment, it is assumed that the area in the hall is divided in advance for each floor. Each floor is pre-set with an entrance and an exit. In addition, in the present embodiment, the case where the product with a high point is determined to be high in priority is described, but the product with a low point is determined to be high in priority. Those skilled in the art can similarly realize the present invention by changing the method of giving the points.

  A shopper who visits a shopping center selects a product to be purchased from an installation terminal installed at an entrance and the like and inputs it. For example, a product A, a product B, a product C, a product D, and a product E are selected and input. The product identification information of the input product is received by the selected product input receiving unit 2 (S100).

  Further, when setting a route, an input of which product attribute, that is, which of weight, size, temperature, and distance has priority is performed from the installation terminal, and the input is accepted (S110). At this time, the degree of priority over the product attribute may be one, the product attribute with the first priority, the product attribute with the second priority, the product attribute with the third priority, the fourth Ranking may be performed like priority product attributes.

  Based on the product identification information received by the selected product input reception unit 2, the product attribute acquisition unit 4 acquires the product attributes of the products (here, products A to E) from the product attribute storage unit 5 (S120). Then, for the product A, the product attributes of “weight: 50 g”, “size: 300 cubic centimeters”, “temperature: normal temperature”, “distance: 400 m”, “position: shelf on the third floor” are acquired, For product B, the product attributes of “weight: 250 g”, “size: 800 cubic centimeters”, “temperature: −10 ° C.”, “distance: 200 m”, “location: shelf 2 on the second basement floor” are acquired. For product C, the product attributes of “weight: 400 g”, “size: 200 cubic centimeters”, “temperature: 0 ° C.”, “distance: 250 m”, “position: shelf 2 on the second basement floor” are acquired. For the product D, the product attributes of “weight: 2.5 kg”, “size: 24,000 cubic centimeters”, “temperature: normal temperature”, “distance: 350 m”, “position: shelf 18 on the third floor” are set. For product E, Is: 100g "," size: 250 cm3 "," Temperature: 40 ° C. "" Distance: 300 meters "," Position: the obtaining the product attributes of the shelf 38 'of 2 basement.

  In this way, when each product attribute is acquired for the selected product, the point calculation unit 6 first classifies which area the selected product belongs to based on the product attribute (S130). This area can be set arbitrarily and is preferably divided for each area to be settled.

  Then, based on the position information in the product attribute, the point calculation unit 6 classifies the product whose position is “3rd floor” and the product “2nd floor underground”. In the above-described example, “product A” and “product D” are divided into “third floor” areas, and “product B”, “product C”, and “product E” are divided into “second basement” areas.

  Next, the point calculation unit 6 performs ranking for each product attribute to be compared for each area (S140), and calculates points for each product by adding points corresponding to the ranking (S150). ). In other words, in the area of the “3rd floor” position, the product attributes “weight”, “size”, “temperature”, and “distance” are ranked, and points corresponding to the ranking are assigned to each product attribute. Add the points to calculate the points for each product, and rank the product attributes “weight”, “size”, “temperature”, and “distance” in the “basement 2” area. Points corresponding to are added for each product attribute to calculate points for each product.

  Then, when the product attribute “weight” is ranked in the area of the position “3rd floor”, “the first heaviest product: product D” and “the second heaviest product: product A” are obtained. Similarly, in the ranking of the product attribute “size”, “first largest product: product D” and “second largest product: product A”, and the product attribute “temperature” are both at normal temperature, so the same rating (one Product of the first priority temperature). In the product attribute “distance”, “the closest product: product D” and “the second closest product: product A” are displayed. For the ranking for each of these attributes, points with higher to lower ranks are assigned. For example, 1 point is given for the first product and 2 points for the second product. Then, for product A, the product attribute other than the product attribute “temperature” is ranked second, so 7 (= 2 + 2 ++ 1) is given as a point. For product D, 4 (= 1 + 1 + 1 + 1) is given as the point because it is the first rank for product attributes other than the product attribute “temperature”.

  Similarly, in the “second basement floor” area, the product B, the product C, and the product E are ranked for each product attribute, and points are given. Then, 5 points are given for the product B, 9 points are given for the product C, and 10 points are given for the product E. FIG. 5 schematically shows points assigned to each product attribute of each product for each area.

  When the point calculation unit 6 calculates the points of each product for each area in this manner, the sorting unit 7 performs the sorting for each area based on the points so that the products with the highest points are ordered (in order). S160). That is, in the area “3rd floor”, the items are rearranged in the order of “product A” and “product D”, and in the area “second floor”, the items are rearranged in the order of “product E”, “product C”, “product B”. .

  Next, for each area, the route setting unit 8 stores the product location information stored in the product attribute storage unit 5 and the in-store map information storage unit 9 so as to move in order from the product with the highest points. A route is set based on the map information (S170).

  In other words, in the “3rd floor” area, the route from “3rd floor entrance” to “product A” (shelf 20), “product D” (shelf 18), “3rd floor exit” is set, and “underground” In the “2nd floor” area, from “entrance on the second basement floor” to “product E” (shelf 38), “product C” (shelf 20), “product B” (shelf 15), “exit on the second basement floor” Set the route of.

  Next, the route setting unit 8 performs route setting as to which order each area is to be rotated (S180). Here, the route is set on the condition that the movement from the upper floor to the lower floor is performed in order, but the condition may be that the movement from the lower floor to the upper floor is performed in order, or the area ( The condition may be that the number of products for each floor) is moved in order of increasing total points (in descending order).

  Therefore, in the above case, the route setting from the third floor to the second basement floor, that is, the route setting from the “third floor exit” to the “second basement entrance” is performed. Finally, the route setting unit 8 sets the route from the installation terminal currently used by the shopper to the entrance of the first area (route setup from the installation terminal to the “third floor entrance”) and the last area. Set the route from the exit of the shopping center to the exit of the shopping center (setting the route from the “exit on the second basement floor” to the exit of the shopping center). As a result, a route from the current position to the exit of the shopping center can be set.

  The output unit 10 outputs the route set in this way using a printer or a screen (S190). In some cases, an input of an e-mail address of a mobile terminal possessed by a shopper may be accepted, and an e-mail attached with this route may be transmitted to the e-mail address.

  In calculating the points of each area in S150, when the priority input receiving unit 3 inputs a priority for a specific product attribute, the point of the product attribute is multiplied or added by a predetermined coefficient k. Or the like, the point for each product may be calculated.

  For example, when the priority input receiving unit 3 receives an input indicating that weight is prioritized, the point added to the weight is multiplied by a predetermined coefficient k (for example, k = 6) and then added. Then, in the area “3rd floor”, the point given to the product attribute “weight” of the product A is “12”, and the point given to the product attribute “weight” of the product D is “6”. Also, in the area “2nd basement”, the point given to the product attribute “weight” of the product B is “12”, the point given to the product attribute “weight” of the product C is “6”, and the product E is the product E The point given to the attribute “weight” is “18”. Therefore, the total point of product A is “17”, the total point of product D is “9”, the total point of product B is “15”, the total point of product C is “14”, and the total point of product E is “25”. " This is schematically shown in FIG.

  Then, when there is no priority in the area “2nd basement”, the sorting in the sorting unit 7 is in the order of “product E”, “product C”, and “product B”. Accordingly, “product E”, “product B”, and “product C” are obtained, and the product B is moved to the position of the product C before the position of the product C. That is, as a result of the shopper placing importance on the product attribute “weight”, the order of the product B and the product C is switched.

The above-mentioned priority predetermined coefficient k can be set arbitrarily, and a plurality thereof may be provided. In addition, when the product attributes are superior or inferior, a predetermined coefficient may be provided for each product attribute. For example, the predetermined coefficient of the product attribute “weight” is k ₁ , the predetermined coefficient of the product attribute “size” is k ₂ , the predetermined coefficient of the product attribute “temperature” is k _3, and the predetermined coefficient of the product attribute “distance” Is k ₄ . When the shoppers input the product attributes “weight”, “size”, “distance”, “temperature” in descending order of priority, the predetermined coefficients k ₁ = 12, k ₂ = 3 , K ₃ = 1, k ₄ = 2.

  When the predetermined coefficient is set as described above, points given for each product attribute of each product in each area shown in FIG. 5 are schematically shown in FIG. Then, in the area “3rd floor”, the total point of product A is “35”, the total point of product D is “18”, in the area “2nd floor”, the total point of product B is “30”, and the total point of product C is The total point of “28” and product E is “50”. Then, as described above, when there is no priority in the area “2nd floor”, the sorting in the sorting unit 7 is in the order of “product E”, “product C”, and “product B”. By providing the degree, “product E”, “product B”, and “product C” are obtained, and the position of the product B is moved before the position of the product C.

  In addition to the above-described embodiment, a product that a shopper plans to purchase may be set to be purchased at the end (or the second half). In this case, when an input of a product is received by the selected product input receiving unit 2, information (flag) indicating that the purchase is last (or the second half) is set. And when calculating the point with respect to the said goods in the point calculation part 6, the advantage selection coefficient Y is multiplied about the calculated point about the goods with the flag. For example, when it is desired to purchase at the end, the advantage selection coefficient Y is set to be sufficiently large, and the total points of the product of the product are multiplied by the advantage selection coefficient Y to obtain a relatively large number of points. Also, if you want to make purchases in the second half, similarly, by setting a large number of dominant selection coefficients Y, even if the point of the product does not become the maximum, it can be made the top ½. The dominant selection coefficient Y may be set in advance, or may be set by receiving an input from a shopper. The dominant selection coefficient Y may be added in addition to multiplying the total points of the product.

  In addition to the above-described embodiment, the priority may be automatically determined using a membership card. In this case, the hall guidance system 1 further includes a member attribute storage unit (not shown) that stores information about members. The member information includes a member ID (information for identifying a shopper who is a member of the shopping center), name, sex, age, address, telephone number, e-mail address, and the like.

  Further, a membership card in which a member ID is recorded in advance is issued to the shopper. When using the in-house guidance system of the present invention, the shopper reads a member card into a predetermined device (R / W device), and the device reads the member ID recorded on the member card.

  Instead of accepting the input of the priority for the product attribute accepted by the priority input accepting unit 3, the sex, age, etc. of the shopper are determined based on the member ID read from the member card. And, for example, when the gender is female, the elderly person over 60 years old, the child under 15 years old, etc., among the product attributes, “weight” is set as the highest priority, and the information is obtained from the product attributes Pass to part 4.

  By providing such processing, it is possible to automatically determine the priority from information relating to members registered in advance.

According to the above-described invention, when the shopping center is guided to the shopper at the shopping center, the in-building guidance system 1 for guiding the route considering the product attribute and the shopper's priority with respect to the product attribute is possible. Become.
