[0013] 1 shows an example of the configuration of a notification system 100 according to the present invention. The notification system 100 includes a detection unit 110 and an instruction unit 120.

[0014] The detection means 110 detects the removal and return of an object displayed on the shelf. The detection means 110 may detect the removal and return of an object based on an image acquired from a camera (not shown). The camera may be a fixed camera installed for detecting removal and return, or may be a security camera installed for security purposes. The detection means 110 may detect at least one of the removal and return of an object displayed on the shelf.

[0015] The detection unit 110 may also detect the removal and return of an object based on information acquired from a sensor (not shown) installed on a shelf. Examples of the sensor include, but are not limited to, a weight sensor, a pressure sensor, and an infrared sensor.

[0016] Furthermore, the detection unit 110 may detect the removal and return of an object based on the results of reading a wireless tag attached to the object. In this case, the detection unit 110 can detect the removal and return of an object by obtaining the results of reading the wireless tag attached to the object from an antenna (not shown). Note that the methods of detecting the removal and return of an object by the detection unit 110 shown here are merely examples and are not limited to these.

[0017] The instruction means 120 instructs the notification means 110 to issue a notification in a different manner for removal and return based on the detection result of the detection means 110. The instruction means 120 instructs a notification means (not shown) to issue a notification.

[0018] When the detection means 110 detects the removal of an object, the instruction means 120 instructs the notification means (not shown) to issue a first notification. On the other hand, when the detection means 110 detects the return of an object, the instruction means 120 instructs the notification means (not shown) to issue a second notification.

[0019] 1, each block included in the notification system 100 indicates a functional unit configuration. Therefore, each block included in the notification system 100 shown in FIG. 1 may be implemented separately in multiple devices and configured as a notification system, or may be implemented in a single device and configured as a notification device.

[0020] The detection method used in the notification system according to the first embodiment will be described with reference to the drawings. Fig. 2 is a flowchart showing an example of the operation of the notification system according to the present invention.

[0021] The detection means 110 detects the removal and return of an object displayed on a shelf (step S11). Then, the instruction means 120 instructs the notification system to issue a notification in a different manner for removal and return based on the detection result of the detection means 110 (step S12), and the notification system ends the processing.

[0022] In the notification system according to the first embodiment, notifications are issued in different modes for pick-up and return based on the detection of pick-up and return, allowing the user to check whether the timing of pick-up or return is correctly detected.

[0023] Furthermore, in the notification system according to the first embodiment, notifications are issued in different modes for removal and return based on the detection of removal and return, allowing the user to confirm whether removal or return was detected based on the notification content, and to check whether the detection content is correct.

[0024] [Second embodiment] In the second embodiment, a more detailed description will be given of a case where the notification system according to the present invention is applied to a retail store. Hereinafter, the same reference numerals will be used to designate the same configurations and operations as those in the first embodiment, and explanations of overlapping parts will be omitted.

[0025] 3 shows an example of the configuration of a notification system 200 according to the present invention. The notification system 200 includes a detection unit 110, an instruction unit 120, and a notification unit .

[0026] The detection means 110 detects when a customer takes an item off the shelf and returns it to the shelf. Here, the "item" in the second embodiment is a specific example of the "object" in the first embodiment.

[0027] In addition to detecting the removal and return of products, the detection means 110 may detect the type of product removed from the shelf and the type of product returned to the shelf. The detection means 110 may also detect the number of products removed from the shelf and the number of products returned to the shelf.

[0028] The detection means 110 may detect the type and number of products based on images acquired from a camera (not shown). The camera may be a fixed camera installed for detecting the type and number of products, or a security camera installed for crime prevention purposes.

[0029] The detection means 110 may also detect the type and number of products based on information obtained from a sensor (not shown) installed on the shelf. Examples of sensors include, but are not limited to, weight sensors, pressure sensors, and infrared sensors. In this case, the type of product can be identified by, for example, comparing the location where the sensor detects the removal and return of a product with the shelf allocation information indicating the display location of the product. Furthermore, for example, if a weight sensor detects a change in weight, the number of products removed from the shelf and returned to the shelf can be identified by dividing the changed weight by the unit weight of the product.

[0030] The detection means 110 may also detect the type and number of products based on the results of reading a wireless tag attached to the product. For example, the wireless tag stores product information about the product to which the wireless tag is attached. In this case, the detection means 110 can detect the type and number of products by obtaining the results of reading the wireless tag attached to the product from an antenna (not shown). Note that the method of detecting the type and number of products by the detection means 110 shown here is an example and is not limited to this.

[0031] The instruction means 120 instructs the notification means 130 to issue a first notification or a second notification based on the detection result of the detection means 110. The detection result of the detection means 110 includes the detection result of the customer removing an item from the shelf and returning it to the shelf. The detection result of the detection means 110 may further include at least one of the type of item removed from the shelf, the type of item returned to the shelf, the number of items removed from the shelf, and the number of items returned to the shelf.

[0032] The notification means 130 notifies the customer who has taken out or returned an item. Specific examples of the notification means 130 include, but are not limited to, shelf tags attached to shelves corresponding to each product, mobile terminals operated by customers, shopping carts, speakers, and signage. The mobile terminals may be terminals owned by the customer or terminals rented by the retail store. The shopping cart may also be equipped with a terminal operated by the customer.

[0033] 4 shows an example of an electronic shelf label 131 that functions as the notification unit 130. The electronic shelf label 131 includes a display unit 132 and a light-emitting unit 133. Alternatively, the electronic shelf label 131 may include two light-emitting units (light-emitting unit 133 and light-emitting unit 134) as shown in FIG.

[0034] As an example of an instruction given by the instruction unit 120, the instruction unit 120 instructs the notification unit 130 to issue an alert by illuminating a light-emitting unit included in the notification unit 130. In this case, the light-emitting method is made different for the first alert and the second alert. For example, the light-emitting unit is made to emit light in different colors for the first alert and the second alert. More specifically, for example, for the first alert, the light-emitting unit 133 of the electronic shelf label 131 shown in FIG. 4 is made to emit green light. On the other hand, for the second alert, the light-emitting unit 133 of the electronic shelf label 131 shown in FIG. 4 is made to emit red light.

[0035] As another example of different light-emitting methods, the light-emitting duration may be different between the first and second notifications. More specifically, for example, in the first notification, the light-emitting unit 133 of the electronic shelf label 131 shown in Fig. 4 is caused to emit light for one second. On the other hand, in the second notification, the light-emitting unit 133 of the electronic shelf label 131 shown in Fig. 4 is caused to emit light for three seconds.

[0036] As another example of different light-emitting methods, different light-emitting units are used for the first and second notifications. More specifically, for example, the light-emitting unit 133 of the electronic shelf label 131 shown in Fig. 5 is caused to emit light for the first notification. On the other hand, the light-emitting unit 134 of the electronic shelf label 131 shown in Fig. 5 is caused to emit light for the second notification.

[0037] As another example of an instruction given by the instruction means 120, the instruction means 120 instructs the notification means 130 to issue a notification by display. In this case, the first notification and the second notification are displayed differently. For example, the first notification and the second notification are displayed with different display contents. More specifically, for example, the first notification is a display including content that removal has been detected, and the second notification is a display including content that return has been detected.

[0038] An example of a case where the notification unit 130 notifies by display is shown in Fig. 6. Fig. 6 shows an example of an electronic shelf label 131 functioning as the notification unit 130. In Fig. 6, a display 135 indicating removal is displayed on the display unit 132. In Fig. 6, the display 135 indicating removal is displayed together with the product name and price, but the display method is not limited to this. For example, the display showing the product name and price and the display 135 indicating removal may be switched at a predetermined time interval.

[0039] 7 shows an example of a case where the notification unit 130 notifies by display. FIG. 7 shows an example of an electronic shelf label 131 that functions as the notification unit 130. In FIG. 7, a display 136 indicating a return is displayed on the display unit 132. In FIG. 7, the display 136 indicating a return is displayed together with the product name and price, but the display method is not limited to this. For example, the display showing the product name and price and the display 136 indicating a return may be switched at predetermined time intervals.

[0040] As another example of an instruction given by the instruction means 120, the instruction means 120 instructs the notification means 130 to issue an audio notification. In this case, the audio is made different between the first notification and the second notification. For example, the content of the audio notification is made different between the first notification and the second notification. More specifically, for example, the first notification is an audio notification including content that removal has been detected, and the second notification is an audio notification including content that return has been detected.

[0041] As another example of an instruction given by the instruction means 120, the instruction means 120 instructs the notification means 130 to issue a notification by vibration. In this case, the vibration method is different for the first notification and the second notification. For example, the first notification and the second notification are vibrated by different numbers of vibrations. More specifically, for example, the first notification is vibrated once and the second notification is vibrated twice.

[0042] As another example of different vibration methods, the vibration duration may be different between the first and second notifications. More specifically, the first notification may be vibrated for one second, and the second notification may be vibrated for three seconds.

[0043] The instruction means 120 may further instruct the notification means 130 to issue a notification corresponding to the number of products removed from the shelf detected by the detection means 110 and the number of products returned to the shelf.

[0044] For example, the instruction unit 120 instructs the notification unit 130 to emit light the same number of times as the number of products taken out or returned. As another example, the instruction unit 120 instructs the notification unit 130 to display information indicating the number of products taken out or returned.

[0045] FIG. 8 shows an example of a case where the notification means 130 displays information indicating the number of products that have been removed. FIG. 8 shows an example of an electronic shelf label 131 that functions as the notification means 130. In FIG. 8, a display 135 indicating removal is displayed on the display unit 132. The display 135 indicating removal includes information indicating the number of products that have been removed from the shelf detected by the detection means 110. In FIG. 8, the display 135 indicating removal is displayed together with the product name and price, but the display method is not limited to this. For example, the display may alternate between the display indicating the product name and price and the display 135 indicating removal at a predetermined time interval.

[0046] 9 shows an example of a case where the notification unit 130 displays information indicating the number of returned products. FIG. 9 shows an example of an electronic shelf label 131 that functions as the notification unit 130. In FIG. 9, a display 136 indicating a return is displayed on the display unit 132. The display 136 indicating a return includes information indicating the number of products returned to the shelf detected by the detection unit 110. In FIG. 9, the display 136 indicating a return is displayed together with the product name and price, but the display method is not limited to this. For example, the display may alternate between the display indicating the product name and price and the display 136 indicating a return at a predetermined time interval.

[0047] As yet another example, the instruction means 120 may instruct the notification means 130 to issue a voice notification including information indicating the number of products that have been taken out or returned.

[0048] In addition, the instruction means 120 may instruct the notification means 130 to make different notifications depending on whether the number of items removed from the shelf detected by the detection means 110 and the number of items returned to the shelf is one or multiple.

[0049] For example, the instruction means 120 instructs the light-emitting unit of the notification means 130 to emit different colors depending on whether one product has been removed or returned or whether multiple products have been removed or returned. More specifically, for example, the light-emitting unit emits green light when one product has been removed, and emits blue light when multiple products have been removed. Furthermore, the light-emitting unit emits red light when one product has been returned, and emits yellow light when multiple products have been returned.

[0050] Although a number of examples of instructions given by the instruction unit 120 to the notification unit 130 have been given above, these examples may be combined for implementation.

[0051] The operation of the notification system according to the second embodiment will be described with reference to the accompanying drawings. Fig. 10 is a flowchart showing an example of the operation of the notification system according to the present invention.

[0052] The detection means 110 detects the removal and return of a product displayed on a shelf (step S21). Then, the instruction means 120 instructs the system to issue a first or second notification based on the detection result of the detection means 110 (step S22). The notification means 130 issues a notification to the customer who has removed or returned the product based on the instruction of the instruction means 120 (step S23), and the notification system ends its processing.

[0053] In the notification system according to the second embodiment, the first notification or the second notification is issued based on the detection of the removal or return of the item, thereby enabling the customer to check whether the removal or return of the item is correctly detected at the time of the removal or return.

[0054] In addition, the notification system according to the second embodiment issues the first or second notification based on the detection of removal and return, allowing the customer to confirm whether removal or return was detected based on the notification content, and to check whether the detection content is correct.

[0055] In the notification system according to the second embodiment, the notification may be performed by emitting light from a light-emitting unit included in the notification means, thereby allowing the detection content to be visually confirmed.

[0056] Furthermore, the notification system according to the second embodiment may notify the user by displaying the information. This allows the user to check the details of the detection in more detail. For example, by displaying the details of the detection in text, the user can be notified of detailed information such as whether the detection occurred during pick-up or return, which product was the target of the detection, and how many products were detected.

[0057] Furthermore, the notification system according to the second embodiment may provide audible notification. This allows the detection result to be confirmed audibly, and the notification can be provided without restricting the customer's movements. For example, audible notification allows the customer to immediately move on to another product after picking up and returning the product.

[0058] Furthermore, the notification system according to the second embodiment may notify the customer by vibration, which allows the customer to tactilely confirm the detected content, making it easier for the customer to notice the notification.

[0059] Furthermore, the notification system according to the second embodiment may notify the customer of the number of products removed from the shelf and the number of products returned to the shelf, thereby enabling the customer to check whether the detected number is correct.

[0060] Furthermore, the notification system according to the second embodiment may issue different notifications depending on whether the number of products removed from the shelf or returned to the shelf is one or more, allowing customers to check whether the detected number is correct.

[0061] [Third Embodiment] Compared to the notification system 100 of the first embodiment, the notification system 300 of the third embodiment differs in that it includes a specification unit 140. Hereinafter, the same configurations and operations as those of the second embodiment will be denoted by the same reference numerals, and explanations of overlapping parts will be omitted.

[0062] 11 shows an example of the configuration of a notification system 300 according to the present invention. The notification system 300 includes a detection unit 110, an instruction unit 120, and an identification unit 140. The notification system 300 according to the present invention may also include a notification unit 130.

[0063] The identification unit 140 identifies the number of objects displayed on the shelf after the removal and return are detected. The identification unit 140 may identify the number of objects displayed on the shelf after the removal and return are detected based on an image acquired from a camera (not shown). The camera may be a fixed camera installed for identifying the number of objects displayed, or may be a security camera installed for security purposes. The identification unit 140 may identify the number of objects displayed on the shelf after at least one of the removal and return is detected.

[0064] The identification unit 140 may also identify the number of objects displayed on the shelf after the removal and return are detected based on information obtained from a sensor (not shown) installed on the shelf. Examples of sensors include, but are not limited to, a weight sensor, a pressure sensor, and an infrared sensor. In this case, the number of objects displayed can be identified by, for example, obtaining the total weight of the objects displayed on the shelf using a weight sensor and dividing this total weight by the unit weight of the object.

[0065] Furthermore, the identification unit 140 may identify the number of objects displayed on the shelf after the removal and return of the objects is detected based on the results of reading the wireless tags attached to the objects. In this case, the identification unit 140 can identify the number of objects displayed by obtaining the results of reading the wireless tags attached to the objects from an antenna (not shown).

[0066] The identification unit 140 may also identify the number of objects displayed on the shelf after the removal and return are detected based on the detection results of the detection unit 110. In this case, the detection unit 110 detects the number of objects removed from the shelf and the number of objects returned to the shelf. A storage unit (not shown) stores the number of objects displayed before the detection unit 110 detected the removal and return of the objects. Specifically, the identification unit 140 identifies the number of objects displayed on the shelf after the removal is detected by subtracting the number of removed objects detected by the detection unit 110 from the number of objects displayed before the detection unit 110 detected the removal of the objects. The identification unit 140 also identifies the number of objects displayed on the shelf after the return is detected by adding the number of returned objects detected by the detection unit 110 to the number of objects displayed before the detection unit 110 detected the return of the objects. The number of displayed objects before the detection unit 110 detects the removal and return of the object may be input and stored by a store clerk, or may be updated and stored based on the identification result by the identification unit. Note that the method of identifying the number of displayed objects by the identification unit 140 shown here is an example and is not limited to this.

[0067] The instruction means 120 further instructs the notification means to issue a notification according to the number of displays identified by the identification means 140.

[0068] For example, the instruction means 120 instructs a third notification when the number of displayed items falls below a predetermined number. The third notification may be, for example, lighting or flashing of a light-emitting unit. The third notification may also be the display of text or an image encouraging the user to replenish items. The third notification may also be the display of text or an image indicating that the number of displayed items is low. The third notification may also be an audio announcement encouraging the user to replenish items. The third notification may also be an audio announcement indicating that the number of displayed items is low. Note that the examples of the third notification shown here are merely examples and are not limited to these. The examples shown here may also be combined to form the third notification.

[0069] The operation of the notification system according to the third embodiment will be described with reference to the accompanying drawings. Fig. 12 is a flowchart showing an example of the operation of the notification system according to the present invention.

[0070] The detection means 110 detects the removal and return of an object displayed on a shelf (step S31). The identification means 140 identifies the number of objects displayed on the shelf after the removal and return are detected (step S32). The instruction means 120 then instructs the system to issue an alert based on the detection result of the detection means 110 and the number of objects identified by the identification means 140 (step S33), and the alert system terminates its processing.

[0071] In the notification system according to the third embodiment, notifications are issued in different ways depending on whether the item is being taken out or returned, based on the detection of the item being taken out or returned. This allows the user to check whether the timing of the item being taken out or returned has been correctly detected.

[0072] Furthermore, in the notification system according to the third embodiment, different notifications are issued for removal and return based on the detection of removal and return, allowing the user to confirm whether removal or return was detected based on the notification content, and to check whether the detection content is correct.

[0073] Furthermore, in the notification system according to the third embodiment, a notification is issued according to the number of displayed items identified by the identification means. This allows the user to know the number of displayed items. For example, if the notification system according to the third embodiment is applied to a retail store and the user is a customer, the notification of the number of displayed items allows the user to check whether the number of items taken out or returned by the customer has been correctly detected. For example, if the notification system according to the third embodiment is applied to a retail store and the user is a store clerk, the notification of the number of displayed items allows the user to determine whether maintenance of the shelves, such as stocking or tidying the shelves, is necessary.

[0074] Furthermore, in the notification system according to the third embodiment, a third notification may be issued when the number of displayed items identified by the identifying means falls below a predetermined number. This allows the user to know that the number of displayed items is below the predetermined number. For example, if the notification system according to the third embodiment is applied to a retail store and the user is a customer, the third notification allows the user to know that only a few displayed items remain and to consider purchasing additional items. For example, if the notification system according to the third embodiment is applied to a retail store and the user is a store clerk, the third notification allows the user to know that only a few displayed items remain and to know that stocking is necessary.

[0075] In each embodiment of the present disclosure, each component of each notification system is represented by a functional block.
