DETAILED DESCRIPTION
A digital sign uses an RFID sensor to detect the identity of merchandise placed on a merchandise support unit associated with the sign. Examples of merchandise support units include shelves, gondolas, carousels, peg boards, and the like, found in retail stores. The digital sign compares the merchandise on the merchandise support unit to expected merchandise that has been assigned to the merchandise support unit. If more than a threshold number of incorrectly stocked items are present on the merchandise support unit, the digital sign displays a stocking alert such as a color code to indicate to store employees that some items on the merchandise support unit need to be moved. If the quantity of one type of incorrectly stocked items exceeds a second threshold, the digital sign automatically alters itself to provide a split screen display in which one portion of the display provides information about items originally assigned to the merchandise support unit and another portion of the display provides information about the incorrectly stocked items. Thus, the digital sign adapts to the incorrectly stocked items and provides sales information about the incorrectly stocked items in order to improve sales but only if the number of incorrectly stocked items exceeds a threshold that warrants the change to the digital sign.
In further embodiments, a handheld device may interrogate a digital or electronic sign positioned on a merchandising unit to request an identification of incorrectly stocked items on the merchandising unit. The digital sign, which displays information about items on the merchandising unit, returns identifiers for incorrectly stocked items to the handheld device. The display on the handheld device then displays a description of at least one incorrectly stocked item.
FIG. 1 provides an example of a merchandising unit 100 having a merchandise support unit 102 and an electronic or digital sign 104. Merchandise support unit 102 supports a plurality of items or merchandise such as T-shirts 106, 108 and 110 and can take the form of shelves, a gondola, a peg board, or a carousel, for example. Electronic sign 104 is structurally supported by merchandise support unit 102, although in other embodiments, electronic sign 104 may be independently supported. Electronic sign 104 provides an electronic display 112 that can display various types of information. In accordance with one embodiment, electronic display 112 is a Liquid Crystal Display (LCD). However, other types of displays may be used.
In FIG. 1, electronic display 112 describes the merchandise on merchandise support unit 102 by providing the name 114, shown as “Short Sleeve T-shirts”, the price 116, shown as “$9.99,” and a sale identifier 118 indicating that the merchandise on merchandise support unit 102 is on sale.
FIG. 2 provides a block diagram of an electronic or digital sign 104, a server 200 and a handheld device 202. As shown in FIG. 2, electronic sign 104 includes electronic display 112, display controller 204, processor 206, memory 208 and communication bus 210. Electronic sign 104 also includes an RFID sensor 214, which detects radio frequency signals produced by RFID transmitters 216 on merchandise 218. The radio frequency signals provided by RFID transmitters 216 include merchandise identifiers that identify merchandise 218. Such RFID transmitters 216 may be provided within tags connected to the merchandise or within containers holding the merchandise, for example. RFID sensor 214 converts each RFID signal into a merchandise identifier that is provided to processor 206 along communication bus 210. Although Radio Frequency Identification is described herein, other communication standards may be used in which a transmitter on a piece of merchandise emits a signal that is sensed by a sensor within electronic sign 104 to identify the piece of merchandise.
FIG. 3 provides a flow diagram of a method implemented by electronic sign 104 to provide merchandise information on electronic display 112. In step 300, electronic sign 104 displays information for correctly stocked items on electronic display 112. To do this, processor 206 first determines what items have been designated for the merchandise support unit associated with electronic sign 104 by retrieving identifiers for correctly stocked items 220 stored in memory 208. In accordance with one embodiment, the identifiers for correctly stocked items 220 are initially provided to electronic sign 104 by server 200 through a network interface 224, such as a wired Local Area Network (LAN) interface or a wireless interface. In accordance with one embodiment, the identifiers for correctly stocked items 220 are taken from a merchandise database 222, which designates a merchandise support unit for each piece of merchandise in a store. In accordance with some embodiments, the identifiers for correctly stocked items are pushed from server 200 to electronic sign 104. In other embodiments, electronic sign 104 periodically requests the identifiers for correctly stocked items. In accordance with one embodiment, server 200 communicates with a plurality of electronic signs and is able to store identifiers for correctly stocked items in each of the plurality of electronic signs.
Based on the identifiers for correctly stocked items 220, processor 206 accesses merchandise display descriptions 212 in memory 208 to retrieve information about the correctly stocked items. This information can include a description of the correctly stocked items, the price of the items and an indication of whether the items are on sale. In further embodiments, the displayed description may include style(s) of the items, size(s) of the items and/or color(s) of the items. Processor 206 provides the retrieved merchandise display descriptions to display controller 204 through communication bus 210. Display controller 204 then sends display signals to electronic display 112 to show the merchandise display description.
At step 302, electronic sign 104 detects merchandise near the electronic sign such as merchandise on the merchandise support unit 102. To detect merchandise 218 near the electronic sign, electronic sign 104 uses RFID sensor 214 to sense the RFID signals produced by RFID transmitters 216 on the merchandise 218. In accordance with one embodiment, merchandise is considered to be near electronic sign 104 if RFID sensor 214 can detect the RFID signals produced by the transmitters on the merchandise. In other embodiments, the magnitude of the RFID signal detected by RFID sensor 214 must exceed a set threshold in order for the merchandise to be considered to be near electronic sign 104.
At step 304, processor 206 compares the merchandise identifiers provided by RFID sensor 214 to identifiers for correctly stocked items 220. Processor 206 then determines if there are any incorrectly stocked items on the merchandise support unit associated with electronic sign 104 at step 306. An incorrectly stocked item, also referred to as a misshelved item, is an item that is on the merchandise support unit but has not been assigned to the merchandise support unit and thus is not listed in correctly stocked items 220 for the merchandising unit. Items can be incorrectly stocked when an employee places the item in an incorrect location or when a customer moves an item from one merchandise support unit to another. If there are no incorrectly stocked items at step 306, the process returns to step 302 where electronic sign 104 once again detects items near electronic sign 104. In other embodiments, processor 206 forwards the detected merchandise identifiers to server 200, which then performs steps 304 and 306 to determine if there are any incorrectly stocked items near electronic sign 104.
If there is an incorrectly stocked item at step 306, processor 206 stores the identifiers for the incorrectly stocked items and requests display information for the incorrectly stocked items at step 307. In particular, the merchandise identifiers from RFID sensor 214 for the incorrectly stocked items are stored in incorrectly stocked items 234 of memory 208. In accordance with one embodiment, processor 206 requests display information for the incorrectly stocked items from server 200 through network interface 224. Server 200 accesses a display information database 230 to acquire the display information for the incorrectly stocked items and returns the information through network interface 224 to processor 206. The information obtained by processor 206 from server 200 can include attributes of the items such as the name, size, price, color, brand and style and whether the incorrectly stocked merchandise is on sale.
At step 308, processor 206 groups the incorrectly stocked items into one or more item types based on the information obtained for the incorrectly stocked items. This grouping can be done on the basis of one or more of the attributes of the incorrectly stocked items, such as the names, sizes, colors, styles or brands of the incorrectly stocked items.
At step 309, processor 206 determines if the quantity of a type of incorrectly stocked item is greater than a split-screen threshold 226 stored in memory 208. Split-screen threshold 226 represents the quantity of a type of item that must be present on a merchandise support unit to trigger a change in the electronic display to show information about that type of incorrectly stocked item. If the quantity of at least one type of incorrectly stocked item is not greater than split-screen threshold 226 at step 309, the quantity of merchandise items that are not described on display 112 is compared to a set of alert thresholds 228 at step 310. A merchandise item is considered to not be described on display 112 if display 112 does not provide any information about the merchandise item.
Alert thresholds 228 are a collection of thresholds for quantities of incorrectly stocked items that will cause various alerts to be displayed on electronic display 112. In accordance with one embodiment, alert thresholds 228 consist of three thresholds: a low alert threshold, a middle alert threshold, and a high alert threshold. If the quantity of incorrectly stocked items is greater than at least one of the alert thresholds at step 312, the electronic display 112 is altered at step 314 to provide a visual alert that incorrectly stocked items are present on the merchandise support unit. In accordance with an embodiment where there are three separate thresholds, there are three different visual alerts that can be displayed.
FIG. 4 provides an example of electronic display 112 altered to provide an alert 400 in response to an incorrectly stocked item 402 being present on merchandise support unit 102. As shown in FIG. 4, incorrectly stocked item 402 is a collared shirt which has been misshelved on short sleeve T-shirt merchandise support unit 102. In accordance with some embodiments, alert 400 is a colored alert where the color of the alert indicates how many incorrectly stocked items are on the merchandise support unit. In accordance with one particular embodiment, alert 400 is yellow indicating that the lowest threshold has been exceeded but the middle threshold has not been exceeded.
FIG. 5 provides an example of a second alert 500 displayed on electronic display 112 that is colored a second color, such as orange, to indicate that the number of incorrectly stocked items exceeds a second or middle threshold but not a third or high threshold. For example, in FIG. 5, four collared shirts 402, 501, 502, and 504 have been incorrectly stocked on merchandise support unit 102.
FIG. 6 provides an example of a third alert 600 on display 112 that is colored a third color, such as red, to indicate that the quantity of incorrectly stocked items exceeds a third or high threshold. In particular, in FIG. 6, collared shirts 402, 501, 502, and 504 have been incorrectly stocked on merchandise support unit 102 as well as long sleeve shirts 601, 602 and 604.
Thus, as shown in FIGS. 4, 5 and 6, by using different alert colors, electronic display 112 is able to indicate different degrees of misshelving on merchandise support unit 102 and thereby allow employees to prioritize which merchandise support units to reorganize first.
If the quantity of at least one type of incorrectly stocked item is greater than split-screen threshold 226 in step 309, the process continues at step 316 where processor 206 generates sign information for all item types that exceed the split-screen threshold. In accordance with one embodiment, generating sign information for an item type comprises selecting information from the information obtained at step 307. In accordance with one embodiment, the information that is selected is information that is common to the merchandise items assigned to the item type. For example, the name, color, style, price and whether the item is on sale.
The generated sign information is then used to alter the merchandise display description 212 at step 320 so that the altered merchandise display description 212 provides a split screen with a portion of the split screen showing information about the correctly stocked items and a portion of the split screen showing information for each item type that exceeds the split-screen threshold. For example, the merchandise display description 212 can be altered to include a price for an incorrectly stocked item type that exceeds the split-screen threshold. In accordance with one embodiment, the altered merchandise display description 212 does not provide information about all incorrectly stocked items on the merchandise support unit. If processor 206 determines that the quantity of an incorrectly stocked item type does not exceed the split-screen threshold, merchandise display description 212 is not altered to include information about those incorrectly stocked items. Thus, the split-screen display may show information for some incorrectly stocked items on the merchandise support unit while not showing information for other incorrectly stocked items.
Processor 206 then provides the altered merchandise display description 212 to display controller 204, which alters electronic display 112 to display the altered merchandise display description 212 such that sign information is displayed for both the correctly stocked items and the incorrectly stocked item types that exceeded the split-screen threshold.
FIG. 7 provides an example of a split screen shown on electronic display 112. On electronic display 112, the correctly stocked items are shown in a correctly stocked display area 700 and the incorrectly stocked item types that exceed the split-screen threshold are shown in an incorrectly stocked display area 702. In FIG. 7, collared shirts 704, 706, 708, 710, 712, 714 and 716 are all the same type and this quantity of collared shirts exceeds the split-screen threshold.
As shown in FIG. 7, incorrectly stocked display area 702 displays information such as the name 718 of the incorrectly stocked items and the price 720 of the incorrectly stocked items. In additional embodiments, an indication of whether the incorrectly stocked items are for sale as well as sizes, colors and styles of the incorrectly stocked items may be provided in incorrectly stocked display area 702. Correctly stocked display area 700 also includes a name 722 for the correctly stocked items, a price 724 for the correctly stocked items and a sale identifier 726 for the correctly stocked items. In further embodiments, correctly stocked display area 700 may also include descriptions of the sizes, colors and styles of the correctly stocked items.
Although the split screen of electronic display 112 is shown as being vertically divided into two halves, in other embodiments, the split screen may be horizontally divided or may be diagonally divided. Further, although only two areas are shown in the split-screen format, if more than one type of incorrectly stocked item exceeds the split-screen threshold, electronic display 112 may be divided into more than two areas with a separate area for each type of merchandise that exceeds the split-screen threshold.
After step 320, the process continues at step 310 where the quantity of items that are not described on display 112 is compared to the alert thresholds. If the quantity of items that are not described on display 112 is greater than an alert threshold at step 312, electronic display 112 is altered to provide an alert at step 314.
FIGS. 8, 9 and 10 provide examples of modified split-screen displays showing incorrectly stocked item alerts. In particular, the incorrectly stocked item alerts of FIGS. 8, 9 and 10 are colored alerts wherein the color of the alert indicates a quantity of incorrectly stocked merchandise that is not described in the altered display information.
In FIG. 8, electronic display 112 is shown as having correctly stocked display area 700, incorrectly stocked items display area 702 and incorrectly stocked items alert 800. In accordance with one embodiment, alert 800 is colored a first color, such as yellow, to indicate that more than a lowest alert threshold of incorrectly stocked items is present on merchandise support unit 102. Note that in FIG. 8, collared shirts 704, 706, 708, 710, 712, 714 and 716 are present and incorrectly stocked but only long sleeve shirts 801 and 802 cause alert 800 to be displayed on electronic display 112. Collared shirts 704, 706, 708, 710, 712, 714 and 716 cause incorrectly stocked area 702 to be displayed on electronic display 112 so that a description of the collared shirts and the price of the collared shirts can be presented to the consumer. Collared shirts 704, 706, 708, 710, 712, 714 and 716 do not affect the type of alert 800 provided in electronic display 112.
In FIG. 9, a second alert 900 is provided indicating that the quantity of incorrectly stocked items exceeds a second larger threshold. In accordance with one embodiment, second alert 900 is colored a second color, such as orange. As shown in FIG. 9, collared shirts 704, 706, 708, 710, 712, 714 and 716 are present on merchandise support unit 102 but do not contribute to the selection of alert 900. Instead, the collared shirts cause electronic display 112 to be split into incorrectly stocked items display area 702 and correctly stocked items display area 700. In FIG. 9, long sleeve shirts 801 and 802 have been joined by long sleeve shirts 901 and 902, causing the change in the stocking alerts on electronic display 112.
FIG. 10 provides an example of a third alert 1000, which in accordance with one embodiment is colored a third color, such as red, to indicate that the quantity of incorrectly stocked items exceeds a highest alert threshold. In FIG. 10, collared shirts 704, 706, 708, 710, 712, 714 and 716 are present but do not affect the selection of alert 1000. Instead, the collared shirts cause electronic display 112 to be split into an incorrectly stocked items area 702 and a correctly stocked items display area 700. In FIG. 10, incorrectly stocked items 801, 802, 901 and 902 have been joined by incorrectly stocked items 1001 and 1002. These additional incorrectly stocked items cause alert 1000 to be displayed instead of alert 900 of FIG. 9, thereby indicating that more incorrectly stocked items are present on merchandise support unit 102 in FIG. 10 than in FIG. 9.
In the discussion above, processor 206 is shown to have performed the steps of FIG. 3. In other embodiments, server 200 stores split-screen thresholds 226, alert thresholds 228, correctly stocked items 220, incorrectly stocked items 234 and merchandise display descriptions 212 and server 200 performs steps 304, 306, 307, 308, 309, 310, 312 and 316. Further, server 200 provides instructions to processor 206 to perform steps 300, 314 and 320 to alter the electronic display.
In accordance with further embodiments, electronic sign 104 is capable of being interrogated by a handheld device 202 so that electronic sign 104 will provide merchandise identifiers for incorrectly stocked items that processor 206 has identified. Handheld device 202 may be any mobile device such as a mobile phone, a personal digital assistant, a tablet computer or a dedicated handheld device produced specifically for retail applications, for example.
FIG. 11 provides an example of a split screen shown on an electronic display 1100 attached to a shelving unit 1102. On electronic display 1100, the correctly stocked items are shown in a correctly stocked display area 1104 and the incorrectly stocked item types that exceed the split-screen threshold are shown in an incorrectly stocked display area 1106. In FIG. 11, boots, such as boots 1108, are the correctly stocked items and shoes, such as shoes 1110, are incorrectly stocked items that exceed the split-screen threshold.
As shown in FIG. 11, incorrectly stocked display area 1106 displays information such as the name 1118 of the incorrectly stocked items and the price 1120 of the incorrectly stocked items. In additional embodiments, an indication of whether the incorrectly stocked items are for sale as well as sizes, colors and styles of the incorrectly stocked items may be provided in incorrectly stocked display area 1106. Correctly stocked display area 1104 also includes a name 1122 for the correctly stocked items, a price 1124 for the correctly stocked items and a sale identifier 1126 for the correctly stocked items. In further embodiments, correctly stocked display area 1104 may also include descriptions of the sizes, colors and styles of the correctly stocked items. In accordance with further embodiments, display 1100 may also include visual alerts that additional items other than shoes 1110 are incorrectly stocked on display unit 1102. These alerts may be similar to the alerts shown in FIGS. 8-10 described above.
Although the split screen of electronic display 1100 is shown as being vertically divided into two halves, in other embodiments, the split screen may be horizontally divided or may be diagonally divided. Further, although only two areas are shown in the split-screen format, if more than one type of incorrectly stocked item exceeds the split-screen threshold, electronic display 1100 may be divided into more than two areas with a separate area for each type of merchandise that exceeds the split-screen threshold.
In FIG. 11, display 1100 is attached to a back panel 1140 of shelving unit 1102 and extends across a top surface 1142 of back panel 1140.
FIG. 12 provides an example of a split screen shown on an electronic display 1200 attached to a shelving unit 1202. On electronic display 1200, the correctly stocked items are shown in a correctly stocked display area 1204 and the incorrectly stocked item types that exceed the split-screen threshold are shown in an incorrectly stocked display area 1206. In FIG. 12, boots, such as boots 1208, are the correctly stocked items and shoes, such as shoes 1210, are incorrectly stocked items that exceed the split-screen threshold.
As shown in FIG. 12, incorrectly stocked display area 1206 displays information such as the name 1218 of the incorrectly stocked items and the price 1220 of the incorrectly stocked items. In additional embodiments, an indication of whether the incorrectly stocked items are for sale as well as sizes, colors and styles of the incorrectly stocked items may be provided in incorrectly stocked display area 1206. Correctly stocked display area 1204 also includes a name 1222 for the correctly stocked items, a price 1224 for the correctly stocked items and a sale identifier 1226 for the correctly stocked items. In further embodiments, correctly stocked display area 1204 may also include descriptions of the sizes, colors and styles of the correctly stocked items. In accordance with further embodiments, display 1200 may also include visual alerts that additional items are incorrectly stocked on display unit 1202. These alerts may be similar to the alerts shown in FIGS. 8-10 described above.
Although the split screen of electronic display 1200 is shown as being vertically divided into two halves, in other embodiments, the split screen may be horizontally divided or may be diagonally divided. Further, although only two areas are shown in the split-screen format, if more than one type of incorrectly stocked item exceeds the split-screen threshold, electronic display 1200 may be divided into more than two areas with a separate area for each type of merchandise that exceeds the split-screen threshold.
In FIG. 12, display 1200 is attached to a shelf 1240 of shelving unit 1202 and is positioned in front of a front surface 1242 of shelf 1240. Display 1200 extends both above and below shelf 1240. In other embodiments, display 1200 may be positioned entirely above shelf 1240 or entirely below shelf 1240.
FIG. 13 provides a flow diagram for using a handheld device to interrogate an electronic sign such as electronic sign 104. In step 1300, a user invokes a sign interrogation application 262, which when executed by processor 261 generates a user interface on electronic display 260 of handheld device 202 for selecting a merchandise support unit. FIG. 14 provides an example of such a user interface 1400 on electronic display 260. User interface 1400 includes a schematic view of a layout of merchandise support units in a retail environment including shelving units 1402, 1404 and 1406 and carousels 1408, 1410, 1412, 1414, 1416 and 1418. Each merchandise support unit displayed in user interface 1400 is a selectable icon that can be selected by tapping on the icon. For example, carousel 1408 is shown as a circular icon that can be selected by tapping on the icon. User interface 1400 also includes an instruction 1420 instructing the user on how to interact with the user interface. Although user interface 1400 includes only icons, in other embodiments, textual descriptions of each of the merchandising units may be provided in user interface 1400 or may be brought up in a pop-up window by selecting one of the displayed icons.
At step 1301, the user selects one of the merchandise support units in user interface 1400. At step 1302, sign interrogation application 262 receives the selection of the merchandise support unit and determines a communication address for an electronic sign associated with the selected merchandise support unit. In some embodiments, the communication address is stored within the handheld device. In other embodiments, processor 261 makes a request through network interface 264 to server 200 for the communication address of the electronic sign. In accordance with one embodiment, the communication address is stored in display information database 230 and is retrieved by server 200 by applying an identifier for the merchandise support unit to display information database 230. Server 200 returns the identified communication address through network interface 264 to processor 261.
For Bluetooth® communications, the communication address can take the form of a name for the electronic sign 104 that has previously been stored in handheld device 202 during a paring process between handheld device 202 and electronic sign 104. For Wi-Fi communications, the communication address can take the form of a network address for electronic sign 104.
At step 1304, sign interrogation application 262 of handheld device 202 uses wireless communication transceiver 266 to transmit a request for an identification of incorrectly stocked items and correctly stocked items to electronic sign 104. Wireless communication transceiver 266 can take the form of a Bluetooth® radio transceiver or a Wi-Fi transceiver. The request is sent using the communication address identified in step 1302. In electronic sign 104, the request is received by a wireless communication transceiver 268 that can be either a Bluetooth® radio transceiver, a Wi-Fi transceiver, or some other communication circuit. In response to the request, processor 206 accesses memory 208 to retrieve a merchandise identifier for at least one incorrectly stocked item and, optionally, one or more merchandise identifiers for correctly stocked items. The merchandise identifier for the at least one incorrectly stocked item is retrieved from incorrectly stocked items 234 in memory 208. As discussed above, incorrectly stocked items 234 contain merchandise identifiers for items that have been stocked on the merchandise support unit but that are not assigned to the merchandise support unit. The merchandise identifiers for the correctly stocked items are taken from correctly stocked items 220. Processor 206 then returns the merchandise identifiers for the incorrectly stocked items and the merchandise identifiers for the correctly stocked items to handheld device 202 through wireless communication transceiver 268 and wireless communication transceiver 266 at step 1306. Thus, at step 1306, handheld device 202 receives an identifier of at least one incorrectly stocked item and an identifier for at least one correctly stocked item.
In accordance with one embodiment, the identifiers of the incorrectly stocked items received by handheld device 202 include identifiers for incorrectly stocked item types that are described on a split screen of electronic display 112 and identifiers for incorrectly stocked items that are not described on electronic display 112. In accordance with other embodiments, the identifiers of the incorrectly stocked items received by handheld device 202 only include identifiers for incorrectly stocked items that are not described on electronic display 112.
At step 1308, handheld device 202 uses the merchandise identifiers to request image and/or additional information for the incorrectly stocked items and the correctly stocked items from server 200. This request can be made through network interface 264 by passing the merchandise identifiers to server 200. In accordance with one embodiment, network interface 264 is a wireless network interface such as a Wi-Fi network interface.
