The set value includes “number of empty seats”, “number of empty seats + α (arbitrary value)”, “fixed value (arbitrary value)”, and the like.
　「空席数分」は、そのときの空席数と同数の特典が発行されることを意味する。例えば、空席数が２０の場合、特典（例えば、割引クーポン）の発行数は２０である。 “The number of empty seats” means that the same number of benefits as the number of empty seats at that time is issued. For example, when the number of seats is 20, the number of benefits (for example, discount coupons) issued is 20.
　「空席数分＋α（任意値）」は、空席数に加えて任意値数分の特典が発行されることを意味する。例えば、空席数が２０の場合、αを２０％とすると、発行数は２４である。 ““ Number of seats available + α (arbitrary value) ”means that in addition to the number of seats available, privileges for any number of seats are issued. For example, when the number of vacant seats is 20, if α is 20%, the number of issues is 24.
　また、「固定値（任意値）」は、任意値数分の特典が発行されることを意味する。そのときの空席数に関わらず、発行数は「固定値（任意値）」である。 Also, “Fixed value (arbitrary value)” means that benefits for the number of arbitrary values are issued. Regardless of the number of vacant seats at that time, the number of issued tickets is a “fixed value (arbitrary value)”.
　使用期限９０７は、利用者に発行される特典の使用期限（有効期限）を入力する欄である。設定値は、「空席数に応じて自動」、「固定値」などがある。 The expiration date 907 is a column for inputting the expiration date (expiration date) of the privilege issued to the user. The set value includes “automatic according to the number of seats available”, “fixed value”, and the like.
　例えば、「空席数に応じて自動」が設定された場合、空席状況に応じて、空席数が多いときほど使用期限は短く、空席数が少ないときほど使用期限は長くなるよう自動調整された発行される。また、「固定値（任意値）」が設定された場合、設定された使用期限の特典が発行される。 For example, when “Automatically according to the number of seats” is set, the issuance automatically adjusted so that the expiration date is shorter as the number of seats is larger and the expiration date is longer as the number of seats is smaller, depending on the seat availability. Is done. Further, when “fixed value (arbitrary value)” is set, a privilege for the set expiration date is issued.
　満席時の扱い９０８は、満席時利用者に提供される特典が使用可能となる時期を入力する欄である。店舗が満席である場合、利用者は特典をすぐに使用できない。設定値は、「α（任意値）から使用可能な特典を発行する」、「特典を発行しない」などがある。 “Full occupancy treatment 908” is a column for inputting a time when a privilege provided to a full seat user can be used. When the store is full, the user cannot use the privilege immediately. The set values include “issue a privilege that can be used from α (arbitrary value)” and “do not issue a privilege”.
　「α（任意値）から使用可能な特典を発行する」が設定された場合、その時点の現在時間を基準としてα後経過後から特典が使用可能となる。一方、「特典を発行しない」が設定された場合、満席時の積極的な店舗集客を一時停止すべく、利用者に対して特典が発行されなくなる。 When “Issuing a privilege that can be used from α (arbitrary value)” is set, the privilege can be used after α has elapsed with reference to the current time at that time. On the other hand, when “do not issue a privilege” is set, the privilege is not issued to the user in order to temporarily stop active store attracting when the seats are full.
　登録９０９は、入力情報を登録するための登録ボタンである。 Registration 909 is a registration button for registering input information.
　以上、新規登録画面６００において入力された入力情報は、特典管理ＤＢ１０４ａに格納される（図４参照）。 As described above, the input information input on the new registration screen 600 is stored in the privilege management DB 104a (see FIG. 4).
　＜デジタルサイネージの表示画面例＞
　図１０は、本実施形態に係るデジタルサイネージの表示画面の一例を示す図である。図１０のデジタルサイネージ２０は、店舗の入り口付近など、店舗外からも利用者の人目に付きやすい位置に配置される。 <Example of digital signage display screen>
FIG. 10 is a diagram illustrating an example of a display screen of digital signage according to the present embodiment. The digital signage 20 in FIG. 10 is arranged at a position that is easily visible to the user from outside the store, such as near the entrance of the store.
　デジタルサイネージ２０の表示画面において、表示領域１００１には、制御サーバ１０から配信された店舗のロゴや営業案内などが表示されている。店舗の看板をアピールすることで、利用者の興味を留める。 On the display screen of the digital signage 20, a display area 1001 displays a store logo distributed from the control server 10, a business guide, and the like. Stop appealing to users by appealing the store signboard.
　表示領域１００２には、制御サーバ１０から配信された店舗の空席情報が「空」という空席表示形態で表示されている。リアルタイムに空席状況をアピールすることで、目を留めた利用者に待ちなしで今すぐの入店を促す。 In the display area 1002, the vacant seat information of the store distributed from the control server 10 is displayed in a vacant seat display form of “empty”. By appealing the availability of seats in real time, prompt users to enter the store immediately without waiting.
　表示領域１００３には、制御サーバ１０から配信された店舗の特典コンテンツデータの一例として、現在利用可能なクーポン情報が表示されている。例えば、「すぐ使えるドリンククーポンＧｅｔ！３０％ｏｆｆ」及びＱＲコード（登録商標）が表示されているように、今すぐ特典が利用可能である旨、そのときの空席状況に応じた割引率、及びクーポンサイトへのアクセスコードが示されることで、利用者に今すぐの入店を更に促す。 In the display area 1003, currently available coupon information is displayed as an example of store privilege content data distributed from the control server 10. For example, as shown in “Ready-to-use drink coupon Get! 30% off” and QR code (registered trademark), the benefit is available immediately, the discount rate according to the seat availability at that time, and By showing the access code to the coupon site, the user is further urged to enter the store immediately.
　割引率は、空席状況に応じて一定の範囲（例えば、１０～３０％）で変化する。即ち、店舗の座席が多く空いている場合には（店舗の空席数が多いほど）、提示されるクーポンの割引率が大きくなり、座席が多く空いていない場合には（店舗の空席数が少ないほど）、提示されるクーポンの割引率が小さくなる。 The discount rate varies within a certain range (for example, 10-30%) depending on the seat availability. In other words, when the number of seats in the store is large (the number of seats in the store is large), the discount rate of the coupon presented becomes large, and when there are not many seats available (the number of seats in the store is small) The discount rate of the presented coupon becomes small.
　利用者の中には飲食店を選ぶ際、「直ぐに店に入れるかどうか」、「席が空いているかどうか」、「待ちたくない」という欲求に基づいて、飲食店を選択することがある。 When selecting a restaurant, some users may select a restaurant based on the desires of “whether to enter the store immediately”, “whether seats are available”, or “do not want to wait”.
　利用者は、デジタルサイネージ２０の店舗の看板により興味を惹かれるとともに、一見で店舗には空席があることが分かる。よって、利用者は待ち時間なく入店後直ぐに席に着くことができるため、安心して入店できる。足を運び入店はしてみたものの、席が空いていなかった（満席で入れなかった）という経験をすることはない。 The user is attracted by the signboard of the digital signage 20 store, and at a glance it can be seen that the store has empty seats. Therefore, since the user can get to the seat immediately after entering the store without waiting time, the user can enter the store with peace of mind. I went there and tried to enter the store, but I never experienced that the seats were not available (they were not full).
　このように、座席が空いている場合、店舗側は空席が多いほど積極的に席を埋めたいと考えるが、デジタルサイネージ２０に、リアルタイムに空席情報を大きく表示することで、待ち時間なく入店できることを効果的にアピールできる。 In this way, when the seats are vacant, the store side wants to fill the seats more actively as there are more seats. However, it is possible to enter the store without waiting by displaying the seat availability information on the digital signage 20 in real time. You can effectively appeal what you can do.
　また、店舗側としては空席の多い場合・時間帯において少しでも空席を埋めたいところ、店舗の座席が多く空いている場合には、割引率の大きいクーポン情報が表示されるため、利用者により強く積極的に入店を促し空席を埋めることが可能である。 Also, if there are many vacant seats on the store side, or if you want to fill a vacant seat even a little in the time zone, if there are many vacant seats in the store, coupon information with a large discount rate will be displayed. It is possible to actively entice stores and fill vacancies.
　図１１は、本実施形態に係る携帯端末の特典発行画面の一例を示す図である。携帯端末４０は、店舗の利用者（お客）が所持するスマートフォンである。 FIG. 11 is a diagram illustrating an example of a privilege issue screen of the mobile terminal according to the present embodiment. The portable terminal 40 is a smartphone owned by a store user (customer).
　利用者は携帯端末４０を用いて、デジタルサイネージ２０上に表示されたＱＲコード（登録商標）を読み取る（図１１（Ａ））。ＱＲコード（登録商標）には、制御サーバ１０のＵＲＬ、店舗ＩＤや特典情報等がコード化されて埋め込まれており、ＱＲコード（登録商標）のアプリケーションを介してこれら情報を取得する。 The user reads the QR code (registered trademark) displayed on the digital signage 20 using the portable terminal 40 (FIG. 11A). In the QR code (registered trademark), the URL of the control server 10, the store ID, privilege information, and the like are encoded and embedded, and the information is acquired through an application of the QR code (registered trademark).
　次いで、携帯端末４０はこれら情報に基づきネットワーク５０を介してクラウド上の制御サーバ１０にアクセスすると、携帯端末４０上にはクーポン情報が表示される（図１１（Ｂ））。 Next, when the portable terminal 40 accesses the control server 10 on the cloud via the network 50 based on these pieces of information, coupon information is displayed on the portable terminal 40 (FIG. 11 (B)).
　そして、利用者が「クーポンをＧＥＴする」を押下すると、画面上にクーポン券が発行される（図１１（Ｃ））。利用者は携帯端末４０上に表示されたクーポン券を店舗に提示することで、割引等の特典を得ることができる。 Then, when the user presses “Get Coupon”, a coupon is issued on the screen (FIG. 11C). The user can obtain a privilege such as a discount by presenting the coupon displayed on the mobile terminal 40 to the store.
　＜情報処理＞
　本実施形態に係る制御サーバの情報処理について説明する。 <Information processing>
Information processing of the control server according to the present embodiment will be described.
　（空席情報の更新処理）
　図１２は、本実施形態に係る制御サーバの空席情報の更新処理を示すフローチャート図である。 (Vacancy information update process)
FIG. 12 is a flowchart showing the vacant seat information update process of the control server according to the present embodiment.
　Ｓ１：制御サーバ１０は、監視機器３０から、店舗ＩＤを含む起動信号を受信したか否かを判定する。監視機器３０は、起動時、店舗ＩＤを含む起動信号を制御サーバ１０に送信する。 S1: The control server 10 determines whether or not the activation signal including the store ID is received from the monitoring device 30. The monitoring device 30 transmits an activation signal including the store ID to the control server 10 at the time of activation.
　Ｓ２：制御サーバ１０は、配信処理を実行する。配信処理は、店舗の看板、空席情報、及び特典情報等を配信する処理である。配信処理については後述する（図１２参照）。 S2: The control server 10 executes distribution processing. The distribution process is a process of distributing store signboards, vacant seat information, privilege information, and the like. The distribution process will be described later (see FIG. 12).
　Ｓ３：制御サーバ１０は、監視機器３０から、店舗ＩＤ、座席番号及び座席が非空席状態になったことを示す情報を受信したか否かを判定する。 S3: The control server 10 determines whether the store ID, the seat number, and the information indicating that the seat is in a non-vacant seat state have been received from the monitoring device 30.
　Ｓ４：制御サーバ１０は、Ｓ３の情報に基づいて空席情報を更新する。即ち、店舗ＩＤで特定される店舗において、座席番号で特定される座席の空席状況（ステータス）を、空席状態から非空席状態へ変更する（例えば、図４の「座席番号」が太字表示）。上述したように、監視機器３０は、空席検知デバイスの検知信号に基づいて座席が非空席状態になったことを検知すると、店舗ＩＤ、座席番号及び座席が非空席状態になったことを示す情報を、制御サーバ１０に送信する。 S4: The control server 10 updates the vacant seat information based on the information of S3. That is, in the store specified by the store ID, the vacant seat status (status) of the seat specified by the seat number is changed from a vacant seat state to a non-vacant seat state (for example, “seat number” in FIG. 4 is displayed in bold). As described above, when the monitoring device 30 detects that the seat is in the non-vacant seat state based on the detection signal of the vacant seat detection device, the store ID, the seat number, and the information indicating that the seat is in the non-vacant seat state. Is transmitted to the control server 10.
　次いで、再びＳ２へ進み、更新後の空席情報に応じた配信処理が実行される。 Next, the process proceeds to S2 again, and distribution processing according to the updated vacant seat information is executed.
　（配信処理）
　図１３は、本実施形態に係る制御サーバの配信処理を示すフローチャート図である。本配信処理は、配信部１０２が実行する。 (Delivery process)
FIG. 13 is a flowchart showing distribution processing of the control server according to the present embodiment. This distribution process is executed by the distribution unit 102.
　Ｓ２１：制御サーバ１０は、特典管理ＤＢ１０４ａを参照し、店舗ＩＤに基づいて、「特典管理ＩＤ」、「特典コンテンツデータ」、「割引範囲」、「使用期限」、「満席時の扱い」の特典情報を取得する。 S21: The control server 10 refers to the privilege management DB 104a and, based on the store ID, benefits of “privilege management ID”, “privilege content data”, “discount range”, “expiration date”, “handling when full” Get information.
　Ｓ２２：制御サーバ１０は、空席管理ＤＢ１０４ｂを参照し、「総席数」、「空席数」の空席情報を取得する。 S22: The control server 10 refers to the vacant seat management DB 104b, and acquires vacant seat information of “total seats” and “vacant seats”.
　Ｓ２３：次に制御サーバ１０は、店舗の空席数に応じて、利用者に提示する特典（例えば、クーポン）の割引率を決定する。即ち、店舗の空席数が多いほど大きな割引率となるよう決定し、店舗の空席数が少ないほど小さな割引率を決定する。 S23: Next, the control server 10 determines the discount rate of the privilege (for example, coupon) presented to the user according to the number of seats in the store. That is, a larger discount rate is determined as the number of vacant seats in the store increases, and a smaller discount rate is determined as the number of vacant seats in the store decreases.
　決定方法の一例としては、まず店舗規模によって空席数多寡の重みが異なるため、「空席数」を「総席数」で除算し空席率を算出する。そして「割引範囲」の最小値を空席率０％、最大値を１００％と対応させ、空席率に応じて対応する「割引範囲」の値を、割引率として決定することができる（図１４（Ａ）参照）。例えば、「割引範囲」１０％から３０％の場合、空席率２５％のときは割引率１５％、空席率５０％のときは割引率２５％、空席率７５％のときは割引率２５％、空席率１００％のときは割引率３０％である。なお、「割引範囲」に対応する空席率を必ずしも均等に分布する必要はなく、例えば空席率が高くなるほど割引率の度合いが一気に大きくなるよう偏らせてもよい（図１４（Ｂ）参照）。 As an example of the determination method, first, since the weight of the number of vacant seats varies depending on the store size, the “vacant seat ratio” is calculated by dividing the “vacant seat count” by the “total seat count”. Then, the minimum value of the “discount range” is associated with the vacancy rate 0% and the maximum value is 100%, and the corresponding “discount range” value can be determined as the discount rate according to the vacancy rate (FIG. 14 ( A)). For example, when the “discount range” is 10% to 30%, the discount rate is 15% when the vacancy rate is 25%, the discount rate is 25% when the vacancy rate is 50%, the discount rate is 25% when the vacancy rate is 75%, When the vacancy rate is 100%, the discount rate is 30%. Note that the vacancy rates corresponding to the “discount range” do not necessarily need to be evenly distributed. For example, the vacancy rates may be biased so that the discount rate increases rapidly as the vacancy rate increases (see FIG. 14B).
　Ｓ２４：次に制御サーバ１０は、店舗の空席数に応じて、利用者に提示する特典（例えば、クーポン）の使用期限を決定する。即ち、Ｓ２１で取得した「使用期限」の設定値が「空席数に応じて自動」となっている場合、店舗の空席数が多いほど使用期限を短くなるよう決定し、店舗の空席数が少ないほど使用期限を長くなるよう決定する。店舗側としては空席の多いときに少しでも早く空席を埋めたいところ、特典の使用期限を短くすることで、利用者により今すぐの入店を促すことができる。 S24: Next, the control server 10 determines the expiration date of the privilege (for example, coupon) presented to the user according to the number of seats in the store. That is, when the setting value of “expiration date” acquired in S21 is “automatic according to the number of vacant seats”, it is determined that the expiration date becomes shorter as the number of seats in the store increases, and the number of seats in the store is smaller. Decide to extend the expiration date. If the store wants to fill a vacant seat as soon as possible when there are many vacant seats, the user can be encouraged to enter the store immediately by shortening the expiration date of the privilege.
　なお、使用期限の範囲は、店舗側の利便性を考慮し、例えば３０分（短使用時間）～２時間（最長使用期限）といったように予め制御サーバ１０側で所定の範囲期間を保持しうる。但し、具体的な使用期限をどの程度にするかは、経験則等に応じて店舗側が適切な値を採用することも可能であり、最短使用時間は例えば１０分、最長使用期限は本日中などと定めることもできる。制御サーバ１０は、このように事前に与えられた使用期限の範囲から、店舗の空席数に応じた使用期限を決定する。 Note that the range of the expiration date can hold a predetermined range period in advance on the control server 10 side, for example, 30 minutes (short usage time) to 2 hours (longest usage expiration date) in consideration of convenience on the store side. . However, it is also possible for the store side to adopt an appropriate value for the specific expiration date according to the rule of thumb, etc. The minimum usage time is 10 minutes, the maximum usage date is today, etc. It can also be determined. The control server 10 determines the expiration date according to the number of vacant seats in the store from the range of the expiration date given in advance.
　これに対して、Ｓ２１で取得した「使用期限」の設定値が固定値（例えば、３０分）となっている場合、その固定値に従えばよい。 On the other hand, when the set value of “expiration date” acquired in S21 is a fixed value (for example, 30 minutes), the fixed value may be followed.
　Ｓ２５：次に制御サーバ１０は、デジタルサイネージ２０に、店舗の看板、空席情報、及びクーポン情報を配信する（図１０参照）。 S25: Next, the control server 10 delivers a store signboard, vacant seat information, and coupon information to the digital signage 20 (see FIG. 10).
　具体的に、店舗の看板については、店舗所定の看板の画像や映像が配信されればよい。空席情報については、Ｓ２２で取得した空席情報に基づいて、空席表示形態６０５に従った形態で配信される（図６）。また、クーポン情報は、「特典コンテンツデータ」及びそれにＳ２３で決定した割引率、並びに、制御サーバ１０のＵＲＬと、「特典管理ＩＤ」（又は店舗ＩＤ）と、Ｓ２３で決定した割引率と、及びＳ２４で決定した使用期限との情報を埋め込んだＱＲコード（登録商標）として配信される。 Specifically, for store signboards, it is only necessary to distribute images and videos of store predetermined signboards. The vacant seat information is distributed in a form according to the vacant seat display form 605 based on the vacant seat information acquired in S22 (FIG. 6). The coupon information includes “privilege content data” and the discount rate determined in S23, the URL of the control server 10, “privilege management ID” (or store ID), the discount rate determined in S23, and It is distributed as a QR code (registered trademark) in which information on the expiration date determined in S24 is embedded.
　なお、Ｓ２３において、Ｓ２２で取得した空席情報に基づいて空席が無い場合（満席の場合）、Ｓ２３で「割引範囲」の最小値の割引率を決定し、Ｓ２４で最長の使用期限を決定する。また、Ｓ２１で取得した「満席時の扱い」に従ってクーポン情報を発行する。例えば、「翌日から使用可能な特典を発行する」場合には、図１０の表示領域１００３に「翌日から使えるドリンククーポンＧｅｔ！」と表示されうる。満席時、利用者が今すぐ来店してしまうと空席待ちが発生してしまい、店舗側としてそれほど積極的には今すぐ集客しなくともよい。 In S23, if there is no vacant seat based on the vacant seat information acquired in S22 (when the seats are full), the lowest discount rate of the “discount range” is determined in S23, and the longest expiration date is determined in S24. Also, coupon information is issued according to the “handle when full” acquired in S21. For example, in the case of “issue a privilege that can be used from the next day”, “Drink coupon Get! That can be used from the next day” can be displayed in the display area 1003 of FIG. When the user is full, if the user visits the store immediately, waiting for a vacant seat will occur, and the store does not have to be as active as it is.
　また、ＱＲコード（登録商標）に埋め込まれる情報はあくまで一例であり、利用者が携帯端末４０で読み込んで最終的にクーポン券を発行できればよい。 In addition, the information embedded in the QR code (registered trademark) is merely an example, and it is sufficient that the user can read the information with the mobile terminal 40 and finally issue a coupon.
　（特典発行処理）
　図１５は、本実施形態に係る制御サーバの特典発行処理を示すフローチャート図である。本特典発行処理は、発行部１０３が実行する。 (Bonus issue processing)
FIG. 15 is a flowchart showing privilege issue processing of the control server according to the present embodiment. The issue unit 103 executes the privilege issue process.
　Ｓ３１：制御サーバ１０は、携帯端末４０から特典の発行要求を受信したか否かを判定する。受信した場合、Ｓ３２へ進む。なお、発行要求には、ＱＲコード（登録商標）に埋め込まれていた特典管理ＩＤ（又は店舗ＩＤ）と、割引率と、使用期限との情報が含まれる。 S31: The control server 10 determines whether or not a privilege issue request has been received from the mobile terminal 40. If received, the process proceeds to S32. The issue request includes information on the privilege management ID (or store ID) embedded in the QR code (registered trademark), the discount rate, and the expiration date.
　Ｓ３２：制御サーバ１０は、特典管理ＤＢ１０４ａを参照し、特典管理ＩＤ（又は店舗ＩＤ）に基づいて、「特典コンテンツデータ」、「発行数」、「本日発行済数」の特典情報を取得する。 S32: The control server 10 refers to the privilege management DB 104a, and acquires privilege information of “privilege content data”, “number of issues”, and “number issued today” based on the privilege management ID (or store ID).
　Ｓ３３：制御サーバ１０は、空席管理ＤＢ１０４ｂを参照し、「空席数」の空席情報を取得する。 S33: The control server 10 refers to the vacant seat management DB 104b and acquires vacant seat information of “the number of vacant seats”.
　Ｓ３４：制御サーバ１０は、{「発行数」－ 「本日発行済数」＞０}が成立するか否かを判定する。成立する場合、Ｓ３５へ進む。成立しない場合、Ｓ３７へ進む。 S34: The control server 10 determines whether or not {“issued number” − “number issued today >> 0} is satisfied. If established, the process proceeds to S35. If not, the process proceeds to S37.
　ここで、「発行数」について、図４に示されるように設定値が「空席数分」の場合、Ｓ３３で取得した「空席数」の値を入力する。また、例えば「空席数分＋２０％」の場合、Ｓ３３で取得した{「空席数」＋「空席数」×０．２}の値を入力する。 Here, regarding the “issued number”, when the set value is “for the number of vacant seats” as shown in FIG. 4, the value of “the number of vacant seats” acquired in S33 is input. For example, in the case of “the number of vacant seats + 20%”, the value of “{number of vacant seats” + “number of vacant seats” × 0.2} acquired in S33 is input.
　そして、「発行数」の値から「本日発行済数」の値を減算した値が現在発行可能数であり、現在発行可能数が正数である場合、現在発行可能数がまだ残っている、即ち特典発行が可能となる。一方、現在発行可能数が正数でない場合、現在発行可能数は残っていない、即ち特典発行は不可となる。 And, if the value of “issued today” is subtracted from the value of “issued today” is the current issuable number, and the current issuable number is a positive number, the currently available number still remains, That is, a privilege can be issued. On the other hand, when the current issuable number is not a positive number, the present issuable number does not remain, that is, the privilege cannot be issued.
　店舗側としては空席数分相当枚数の特典（例えば、クーポン券）を発行することで、現在の空席を埋めたいという意図があるため、特典の発行数は、現在の空席数に基づき決定され、具体的には空席数に等しいか、空席数＋α分の特典が発行される。つまり、現在の空席数が多いとき発行数は多く、逆に空席数が少ないとき発行数は少ない。よって、例えば現在の空席数が３０であれば、特典の発行数（例えば、クーポン券）は、３０枚又は３０＋α枚であるし、例えば現在の空席数が５であれば、特典の発行数は、５枚又は５＋α枚である。 Since the store side intends to fill the current vacancies by issuing as many awards as the number of vacancies (for example, coupons), the number of awards issued is determined based on the current number of vacancies, Specifically, benefits equal to the number of vacant seats or the number of vacant seats plus α are issued. In other words, when the number of vacant seats is large, the number of issued seats is large. Thus, for example, if the current number of vacant seats is 30, the number of benefits issued (for example, coupons) is 30 or 30 + α. For example, if the current number of vacant seats is 5, 5 sheets or 5 + α sheets.
　なお、特典の発行数が無制限であるとする場合、特典効果によって空席のあった客席はすぐに満席となり、入店できなかった利用者の顧客満足が低下する可能性がある。 If the number of benefits issued is unlimited, the seats that were vacant due to the benefits will soon become full, and the customer satisfaction of users who could not enter the store may decrease.
　また、「発行数」から「本日発行済数」を減算するのは、先に既に発行済みの特典が使用される可能性を考慮するためである。例えば、空席３０の時点において、先の空席４０の時点で既に１０枚のクーポン券が発行されていた場合、空席３０の時点で発行（配布）すべきクーポン券の枚数は２０（＝３０－１０）である。先の空席３０の時点、既に発行済みの１０枚と、現時点発行可能な２０枚との合計３０枚のクーポン券が使用されることで、空席３０が埋まる計算である。 Also, the reason why the “number issued today” is subtracted from the “number issued” is to take into consideration the possibility that the previously issued benefits will be used. For example, when 10 coupons have already been issued at the time of the vacant seat 30 at the time of the previous vacant seat 40, the number of coupons to be issued (distributed) at the time of the vacant seat 30 is 20 (= 30-10). ). This is a calculation that fills the vacant seat 30 by using a total of 30 coupons of 10 tickets that have already been issued and 20 tickets that can be issued at the time of the previous vacant seat 30.
　Ｓ３５：制御サーバ１０は、特典を発行する。具体的には、「特典コンテンツデータ」、割引率、使用期限等を含む特典券の画面を生成し、携帯端末４０に送信する（図１１（Ｃ）参照）。 S35: The control server 10 issues a privilege. Specifically, a screen of a privilege voucher including “privilege content data”, a discount rate, an expiration date, and the like is generated and transmitted to the mobile terminal 40 (see FIG. 11C).
　Ｓ３６：制御サーバ１０は、「本日発行済数」をカウントアップし、特典管理ＤＢ１０４ａを更新する。 S36: The control server 10 counts up the “number issued today” and updates the privilege management DB 104a.
　Ｓ３７：制御サーバ１０は、特典発行不可を通知する。例えば、「クーポン券の配布は終了しました」といった画面を生成し、携帯端末４０に送信することができる。 S37: The control server 10 notifies that the privilege cannot be issued. For example, a screen such as “coupon distribution has ended” can be generated and transmitted to the mobile terminal 40.
　＜テーブル下へのセンサー設置について＞
　上述したように、空席検知デバイスとして、各座席にセンサー３０ａ、店舗天井や壁面にカメラ３０ｂを設置することにより、監視機器３０は、座席が空席／非空席状態になったことを検知することが可能である（例えば、図５参照）。 <About sensor installation under the table>
As described above, by installing the sensor 30a in each seat and the camera 30b on the store ceiling or wall as the vacant seat detection device, the monitoring device 30 can detect that the seat has become vacant / non-vacant. It is possible (see, for example, FIG. 5).
　しかしながら、例えば、高級レストランなど、内装の意匠やプライバシー保護にこだわる店舗においては、座椅子へのセンサー設置、天井や壁面へのカメラ設置が困難な場合がある。 However, in stores that are particular about interior design and privacy protection, such as high-end restaurants, for example, it may be difficult to install sensors on seats and cameras on the ceiling or walls.
　そこで、このような店舗に対してデジタルサイネージシステム１００の導入を促すため、利用者の視界に一切入らないようにテーブル下にセンサー３０ａを取り付けることが可能である。即ち、テーブル下のセンサー３０ａにより人の足元（腰より下の部位、例えばつま先、足首、下腿、膝、大腿等を含む）を検知することで着座を検知し、座席が空席／非空席状態になったことを検知する。 Therefore, in order to urge the introduction of the digital signage system 100 to such a store, it is possible to attach the sensor 30a under the table so as not to enter the user's field of view. In other words, the sensor 30a under the table detects a person's feet (including parts below the waist, such as toes, ankles, lower legs, knees, thighs, etc.) to detect the seating, and the seat is in an empty / non-vacant state. It detects that it became.
　図１６は、本実施形態に係るセンサースペックの一例を示す図である。図１６のセンサー３０ａにおいて、内部のセンサーが向いている角度が上下方向にそれぞれ角度２７度（ＳＩＤＥ　ＶＩＥＷ）、左右方向にそれぞれ角度２０度（ＴＯＰ　ＶＩＥＷ）となっており、センサー全体の仕様としての受光角度は、上下方向角度５４度、左右方向角度４０度である。なお、実際の検知範囲（検出範囲ともいう）は検知地点との距離によって変化し（図１６の場合は２ｍ先のＸＹ断面地点）、距離が大きくなるほど検知範囲は大きくなる。 FIG. 16 is a diagram illustrating an example of a sensor specification according to the present embodiment. In the sensor 30a of FIG. 16, the angle at which the internal sensor faces is 27 degrees in the vertical direction (SIDE VIEW) and 20 degrees in the left and right direction (TOP VIEW), respectively. The light receiving angle is a vertical angle of 54 degrees and a horizontal angle of 40 degrees. Note that the actual detection range (also referred to as a detection range) varies depending on the distance to the detection point (in the case of FIG. 16, the XY cross-section point 2 meters ahead), and the detection range increases as the distance increases.
　（基本設置例）
　図１７は、本実施形態に係るセンサー基本設置例（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。座る人は、図１７に向かって左右方向に一人ずついるものと想定する。図１８は、本実施形態に係るセンサー基本設置例（ＴＯＰ　ＶＩＥＷ方向）を示す図である。座る人は、図１８に向かって奥と手前に一人ずついるものと想定する。 (Basic installation example)
FIG. 17 is a diagram illustrating a sensor basic installation example (SIDE VIEW direction) according to the present embodiment. It is assumed that one person sits in the left-right direction toward FIG. FIG. 18 is a diagram illustrating a sensor basic installation example (TOP VIEW direction) according to the present embodiment. It is assumed that one person sits in the back and in front of FIG.
　また、本実施形態に係るテーブル５０は、一般的なカフェテーブルとしてテーブル台はサイズ７５０ｍｍ×７５０ｍｍ、高さ６５０ｍｍである。以下同様とする。センサー３０ａは、テーブル５０の下面（裏面）に設置される。下面とは飲食物等が配膳されるテーブル台の上面（表面）の反対側である裏側の板面や、テーブル脚（特にテーブル台と脚との付け根付近）も含む。カフェテーブル５０にセットで備えられる椅子（座席）は向かい合う形で２つ配置され、それぞれの椅子に利用者が２名着座する。 In addition, the table 50 according to the present embodiment is a general café table, and the table base has a size of 750 mm × 750 mm and a height of 650 mm. The same shall apply hereinafter. The sensor 30 a is installed on the lower surface (back surface) of the table 50. The lower surface includes a plate surface on the back side opposite to the upper surface (front surface) of the table base on which food and drinks are arranged, and a table leg (particularly near the base between the table base and the leg). Two chairs (seats) provided as a set on the cafe table 50 are arranged facing each other, and two users are seated on each chair.
　この場合、テーブル５０下から床上まで６５０ｍｍであるので、人の検知範囲（検知可能範囲）は、床上６６２ｍｍ×４７３ｍｍの長方形範囲である。この範囲であれば、テーブル下エリアのみを検知範囲として、着座する人の足元だけを検出することができる。テーブルや座席の周囲・周辺を通行する人を誤検知してしまうことはなく、並び合って設置される隣のテーブルにいる人を誤って検知することもない。即ち、テーブル下エリアが検知範囲となり、これは座っている人の足元だけを検知するのに十分且つ適切な検知範囲である。 In this case, since it is 650 mm from the bottom of the table 50 to the floor, the human detection range (detectable range) is a rectangular range of 662 mm × 473 mm on the floor. Within this range, only the area under the table can be detected, and only the feet of the person sitting can be detected. There is no false detection of people who pass around or around the table or seat, and there is no false detection of people at the next table installed side by side. That is, the area under the table is a detection range, which is a detection range that is sufficient and appropriate for detecting only the feet of a person sitting.
　しかしながらその反面、椅子を引いてテーブルから離れて着座している場合や、着座しているものの膝を曲げて足先を椅子後ろに回している場合など、着座姿勢によっては検知が困難である場合もある。一方、テーブル下エリアを越える検知範囲とする場合、例えばテーブル周囲の単なる歩行者といった非着席者を誤検知してしまう可能性もある。よって、店舗毎に異なるテーブル環境下に応じて、センサー３０ａの取り付け位置、テーブルに対して直角からのレンズの傾き（設置角度）である仰角、センサーが検知可能な受光角度を適切に調整することで、着座検知の精度をより向上することができる。 However, on the other hand, when you are sitting away from the table by pulling a chair, or when you are sitting but bending your knees and turning your toes behind the chair, it may be difficult to detect depending on the sitting posture There is also. On the other hand, when the detection range exceeds the table lower area, there is a possibility that a non-seat person such as a simple pedestrian around the table may be erroneously detected. Therefore, the sensor 30a mounting position, the elevation angle that is the inclination (installation angle) of the lens from the right angle with respect to the table, and the light receiving angle that can be detected by the sensor are appropriately adjusted according to different table environments at each store. Thus, the accuracy of seating detection can be further improved.
　以下、上記のセンサー基本設置例を基本として、以下のいくつかのケース毎にどのようにセンサー３０ａを調整していくのかについて具体的に説明する。 Hereinafter, based on the above sensor basic installation example, how to adjust the sensor 30a for each of the following cases will be specifically described.
　（調整例１）検知対象としたい席の数や位置に応じて調整
　図１９は、本実施形態に係るセンサー調整例１－１（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。図１９に示されるように、１席分だけを検知したい場合、センサー３０ａの仰角をつける（仰角０度から１５度に変更する)、及び／又は、センサー３０ａの受光角度を狭める。例えば、右片側の人のみに照準を当てるため、仰角を１５度つけ、受光角度を上下方向角度３０度と狭く（小さく）すると、検知範囲は床上３７５ｍｍとなるので、片側１席に着座した人の足元を精度良く検知することができる。 (Adjustment example 1) Adjustment according to the number and position of seats to be detected FIG. 19 is a diagram showing a sensor adjustment example 1-1 (SIDE VIEW direction) according to the present embodiment. As shown in FIG. 19, when only one seat is to be detected, the elevation angle of the sensor 30a is increased (the elevation angle is changed from 0 degrees to 15 degrees) and / or the light reception angle of the sensor 30a is narrowed. For example, in order to aim only at the person on the right side, if the elevation angle is 15 degrees and the light receiving angle is narrow (small) as 30 degrees in the vertical direction, the detection range is 375 mm above the floor, so a person sitting on one seat on one side Can be accurately detected.
　なお、仰角とはセンサーをどの角度で設置するかを示すもので、センサーをテーブルの下方向にまっすぐ向けた場合は仰角０度、一定角度を傾けた場合はその角度となる（図２０参照）。 The elevation angle indicates the angle at which the sensor is installed. When the sensor is directed straight down the table, the elevation angle is 0 degree, and when the sensor is inclined at a certain angle, the angle is the angle (see FIG. 20). .
　図２１は、本実施形態に係るセンサー調整例１－２（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。図２１に示されるように、１席分だけを検知したい場合には、基本設置（図１９）の検知範囲を片側１名分の半分にするべく、検知範囲の半分を遮蔽することも可能である。これにより受光角度が上下方向角度２７度となり、検知範囲は半分の床上３３１ｍｍとなるので、片側１席分の着座のみを検知することができる。なお、遮断とは、赤外線を通さない遮断物で覆うもので、例えば樹脂の半円のパーツでレンズの半分を覆うことができる。 FIG. 21 is a diagram showing a sensor adjustment example 1-2 (SIDE VIEW direction) according to the present embodiment. As shown in FIG. 21, when it is desired to detect only one seat, half of the detection range can be shielded so that the detection range of the basic installation (FIG. 19) is half of one person on one side. is there. As a result, the light receiving angle is 27 degrees in the vertical direction, and the detection range is 331 mm above the half of the floor, so that only one seat on one side can be detected. The term “blocking” refers to covering with a blocking material that does not transmit infrared rays. For example, half of the lens can be covered with a semi-circular part of resin.
　一方、テーブルに相向かった２席分など複数の席を特に精度良く検知したい場合などは、仰角を深くする、及び／又は、受光角度を広める。テーブル５０に向かった２席に加え、直角方向にも２名分の座席が追加されたことで、テーブル５０が４名席となったような場合、受光角度を広める。 On the other hand, if you want to detect multiple seats, such as two seats facing each other with high accuracy, increase the elevation angle and / or increase the light reception angle. In addition to the two seats facing the table 50, the seats for two people are added in the right-angle direction, so that the light receiving angle is widened when the table 50 has four seats.
　（調整例２）テーブルの高さに応じて調整
　図２２は、本実施形態に係るセンサー調整例２－１（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。図２３は、本実施形態に係るセンサー調整例２－２（ＴＯＰ　ＳＩＤＥ ＶＩＥＷ方向）を示す図である。背の高いテーブルの場合、誤検知を防ぐため、仰角を浅くする、及び／又は、受光角度を狭める。 (Adjustment Example 2) Adjustment According to Table Height FIG. 22 is a diagram showing a sensor adjustment example 2-1 (SIDE VIEW direction) according to the present embodiment. FIG. 23 is a diagram illustrating a sensor adjustment example 2-2 (TOP SIDE VIEW direction) according to the present embodiment. In the case of a tall table, the elevation angle is made shallower and / or the light receiving angle is made narrower in order to prevent false detection.
　例えば、テーブルの高さが９００ｍｍの背の高いカウンターテーブルである場合、受光角度を上下方向角度５８度から左右方向角度３８度、左右方向４０度から３０度へと狭くすると、テーブル下から９００ｍｍ先の検知範囲は床上６２０ｍｍ×４８２ｍｍである。（図２２、図２３）
　図２４は、本実施形態に係るセンサー調整例２－３（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。図２２及び図２３のようにセンサー３０ａの受光角度は変えずに、仰角をカウンターテーブルの壁側方向に８度傾ける場合には、テーブル下から９００ｍｍ先の検知範囲は床上６８５ｍｍ×６５５ｍｍである。 For example, in the case of a tall counter table with a height of 900 mm, if the light receiving angle is narrowed from a vertical angle of 58 degrees to a horizontal angle of 38 degrees and a horizontal direction of 40 degrees to 30 degrees, the table is 900 mm away from the bottom of the table. The detection range is 620 mm × 482 mm on the floor. (FIGS. 22 and 23)
FIG. 24 is a diagram illustrating a sensor adjustment example 2-3 (SIDE VIEW direction) according to the present embodiment. As shown in FIGS. 22 and 23, when the elevation angle is tilted 8 degrees in the direction of the counter table wall without changing the light receiving angle of the sensor 30a, the detection range 900 mm away from the bottom of the table is 685 mm × 655 mm above the floor.
　これらの方法により背の高いテーブルであっても、テーブル下エリアのみを検知範囲とするので（テーブル下エリア外まで検知範囲とならないので）、テーブルや座席の周囲・周辺を通行する人を誤って検知することなく、着座した人の足元だけを精度良く検知できる。 Even if the table is tall by these methods, only the area under the table is the detection range (because it does not become the detection range outside the table lower area), so people who pass around or around the table or seat are mistakenly Only the feet of the person who is seated can be detected accurately without detection.
　図２５は、本実施形態に係るセンサー調整例２－２（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。背の低いテーブルの場合、検知精度を上げるため、仰角を深くする、及び／又は、受光角度を広める。 FIG. 25 is a diagram showing a sensor adjustment example 2-2 (SIDE VIEW direction) according to the present embodiment. In the case of a short table, in order to increase detection accuracy, the elevation angle is increased and / or the light receiving angle is increased.
　例えば、テーブルの高さが４００ｍｍの背の低いローテーブルである場合、センサー３０ａの受光角度を上下方向角度７６．４度、左右方向角度５３．２度へと広く（大きく）すると、テーブル下から４００ｍｍ先の検知範囲は床上６３０ｍｍ×４００ｍｍである。これにより背の低いテーブルであっても、ほとんどのテーブル下エリアをカバーした検知範囲とするので、着座した人の足元を精度良く検知できる。なお、受光角度を広くするために、図１６とものとはスペックの異なる、受光角度が広い同種の別のセンサーを使用する。 For example, in the case of a low table with a table height of 400 mm, if the light receiving angle of the sensor 30a is widened (increased) to a vertical angle of 76.4 degrees and a horizontal angle of 53.2 degrees, The detection range of 400 mm ahead is 630 mm × 400 mm on the floor. As a result, even if the table is short, the detection range covers most of the area under the table, so that the feet of the person sitting can be detected with high accuracy. In order to widen the light receiving angle, another sensor of the same type with a wide light receiving angle, which is different from the one shown in FIG. 16, is used.
　図２６は、本実施形態に係るセンサー調整例２－３（ＳＩＤＥ　ＶＩＥＷ方向）を示す図である。座る人は、図２５に向かって左右方向に一人ずついるものと想定する。 FIG. 26 is a diagram showing a sensor adjustment example 2-3 (SIDE VIEW direction) according to the present embodiment. It is assumed that one person sits in the left-right direction toward FIG.
　テーブルの高さが４００ｍｍの背の低いローテーブルである場合、センサー３０ａを２個設置することも可能である（例えば、センサー１、センサー２）。例えば、各々のセンサー３０ａの仰角を２７度とし、受光角度を上下方向角度５４度とすると、検知範囲はそれぞれ床上５５０ｍｍの計１１００ｍｍとなる。ローテーブルにセットで備えられる椅子（座席）もまたロータイプであることが多く、人が着座しても足元がテーブル下にかからないこともある。しかしながら、このような場合でもテーブル下エリアを少し椅子方向側へ超えた検知範囲とすることで、着座した人の足元を精度良く検知できる。 When the table is a low table with a height of 400 mm, it is possible to install two sensors 30a (for example, sensor 1 and sensor 2). For example, if the elevation angle of each sensor 30a is 27 degrees and the light receiving angle is 54 degrees in the vertical direction, the detection range is 1100 mm in total, which is 550 mm above the floor. Chairs (seats) provided as a set on a low table are also often of a low type, and even if a person is seated, their feet may not be under the table. However, even in such a case, by setting the detection range slightly beyond the table lower area toward the chair direction, it is possible to accurately detect the feet of the person sitting.
　（調整例３）テーブルと椅子の関係性に応じて調整
　カウンターチェアのようなテーブルの下に足が入るタイプの椅子であれば、誤検知を防ぐため、仰角を浅く、及び／又は、受光角度を狭める。 (Adjustment Example 3) Adjustment according to the relationship between the table and the chair If the chair is a type of foot that fits under the table, such as a counter chair, the elevation angle is shallow and / or the light receiving angle is used to prevent false detection. To narrow.
　テーブル高さ９００ｍｍのカウンターテーブルで、仰角を０度、受光角度を上下方向角度３８度、左右方向角度２０度とし、テーブル下から９００ｍｍの検知範囲を６２０ｍｍ×３１５ｍｍとする（図２２参照）。 A counter table with a table height of 900 mm, the elevation angle is 0 degree, the light receiving angle is 38 degrees in the vertical direction, the horizontal angle is 20 degrees, and the detection range of 900 mm from the bottom of the table is 620 mm × 315 mm (see FIG. 22).
　ソファータイプの椅子であれば、検知精度を上げるため、仰角を深く、及び／又は、受光角度を広める。ソファータイプはテーブルとソファーとの距離・間隔がゆったりと広く取られており、テーブルの下に足元が入りにくいタイプの椅子であるためである。例えば、テーブル高さが４００ｍｍである場合、受光角度が広い同種の別のセンサーを使用して受光角度を上下方向角度９６度、左右方向角度４５度とし、検知範囲を８８８ｎｎ×４００ｍｍとすることで、テーブルサイズよりも広い検知範囲を確保することで、ソファーに着座した人の足元を精度良く検知できる（図２７）。また、センサー３０ａを２個設置することで、テーブルサイズよりも広い検知範囲を確保することも可能である（図２６参照）。なお、テーブルサイズよりも広い検知範囲といっても、最大でソファー本体の位置に届く範囲であれば十分である。 If it is a sofa-type chair, in order to increase detection accuracy, the elevation angle is deepened and / or the light receiving angle is widened. This is because the sofa type is a chair of a type in which the distance and distance between the table and the sofa are wide and the feet are difficult to enter under the table. For example, when the table height is 400 mm, using another sensor of the same type with a wide light receiving angle, the light receiving angle is set to a vertical angle of 96 degrees and a horizontal angle of 45 degrees, and the detection range is set to 888 nn × 400 mm. By securing a detection range wider than the table size, it is possible to accurately detect the feet of the person sitting on the sofa (FIG. 27). In addition, it is possible to secure a detection range wider than the table size by installing two sensors 30a (see FIG. 26). Even if the detection range is wider than the table size, it is sufficient if it is a range that reaches the position of the sofa body at the maximum.
　なお、テーブルサイズよりも広い検知範囲を確保した場合、未着席時はセンサー３０ａの検知範囲が遮蔽されるように椅子を配置ないし収納することで、未着座の状況下において、テーブル周囲を歩く人を誤って検知してしまうことを防止することが可能である。更にテーブルとソファーとの距離を歩行し難い程度の間隔で設置してもよい。この場合、椅子材物質を透過しないタイプのセンサーを選択する。 If a detection range wider than the table size is secured, a person who walks around the table in a non-seated situation can place or store a chair so that the detection range of the sensor 30a is shielded when not seated. It is possible to prevent erroneous detection. Furthermore, the distance between the table and the sofa may be set at an interval that makes it difficult to walk. In this case, a sensor that does not transmit the chair material is selected.
　（調整例４）テーブル形状に応じて調整
　中華料理の円卓のようなテーブルの場合、受光素子を円形に対応させ、検知範囲を円形にすることでテーブル単位での検知を可能とする。これにより円卓テーブルを囲って着座した人の足元だけを精度良く検知できる。 (Adjustment example 4) Adjustment according to the table shape In the case of a table such as a round table of Chinese cuisine, the light receiving element is made to correspond to a circle, and the detection range is made circular, thereby enabling detection in units of tables. As a result, only the feet of the person sitting around the round table can be accurately detected.
　なお、上述の実施形態に係るセンサー３０ａにはスポットタイプの人感センサーを用いたが、センサーのタイプは必ずしもこれだけに限られない。 In addition, although the spot-type human sensor was used for the sensor 30a which concerns on the above-mentioned embodiment, the type of sensor is not necessarily restricted only to this.
　例えば、振動を検知するセンサーと距離測定センサーとを使用する場合、振動センサーで椅子が人の着座動作に基づく振動を検知し、振動を検知したタイミングで距離センサーにて測距する。距離測定センサーについては、背もたれ、座面に取り付けを行い、振動を検知したタイミングで人体との距離を測定する。更に振動の検知について、一定時間以上継続して振動を検知したか否かを示す振動継続保持時間を加味することで精度を向上させる。 For example, when using a sensor for detecting vibration and a distance measuring sensor, the vibration is detected by the chair based on the seating motion of the person by the vibration sensor, and the distance is measured by the distance sensor when the vibration is detected. The distance measurement sensor is attached to the backrest and seat, and the distance to the human body is measured when vibration is detected. Furthermore, regarding the detection of vibration, the accuracy is improved by taking into account the vibration continuation holding time indicating whether or not vibration has been detected for a certain period of time.
　また例えば、振動検知センサーと重量センサーとを使用する場合、振動検知センサーで椅子が振動を検知し、検知したタイミングで椅子の重量を重量センサーにて測定する。 For example, when using a vibration detection sensor and a weight sensor, the vibration is detected by the chair by the vibration detection sensor, and the weight of the chair is measured by the weight sensor at the detected timing.
　以上のように、テーブル下へのセンサー３０ａを設置することで、内装の意匠や店舗利用者のプライバシー保護を確保しつつ、店舗の座席が空席／非空席状態になったことを検知することが可能である。 As described above, by installing the sensor 30a under the table, it is possible to detect that the seat of the store is vacant / non-vacant while ensuring the interior design and the privacy protection of the store user. Is possible.
