The advantages and features of the present invention, and the way of attaining them, will become apparent with reference to embodiments described below in conjunction with the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

The suffixes “module” and “unit” in elements used in description below are only given in consideration of ease in preparation of the specification and do not provide specific meanings or functions. Therefore, the suffixes “module” and “unit” may be used together.

FIG. 1 is a view illustrating a goods purchase system in accordance with one embodiment of the present invention.

With reference to FIG. 1, a goods purchase system 10 in accordance with one embodiment of the present invention is a system to purchase goods at an offline mart 50, and the goods purchase system 10 may include goods purchase apparatuses 100, mobile terminals 600, a server 500, purchased goods calculation apparatuses 32, an entry authentication apparatus 22, and AP apparatuses 70.

The entry authentication apparatus 22 may be installed around a gate 21 of the mart 50 and serve to authenticate entry or exit of a user 10 into or from an entrance zone 22.

The entry authentication apparatus 22 may receive user information and perform user authentication through the received user information.

Otherwise, the entry authentication apparatus 22 may receive user information and transmit the received user information to the server 500, and the server 500 may perform user authentication based on the user information.

As methods of receiving user information, user information may be received from a user's membership card related to the mart 50 wirelessly, user information may be received from a user's mobile terminal 600 wirelessly, or a user's fingerprint may be scanned and corresponding user information may be received from the scanned fingerprint image.

As wireless methods, RFID or NFC communication methods may be exemplarily used and other modifications may be employed.

A plurality of goods purchase apparatuses 100 may be provided around the gate 21 of the mart 50 and a user may pick up one goods purchase apparatus 100.

The goods purchase apparatus 100 may receive user information from a user's membership card related to the mart 50 wirelessly through an image capture unit of the goods purchase apparatus 100 and transmit the received user information to the entry authentication apparatus 22 or the server 500.

Otherwise, the goods purchase apparatus 100 may scan a user's fingerprint through the image capture unit of the goods purchase apparatus 100 and transmit the scanned fingerprint image to the entry authentication apparatus 22 or the server 500.

If the goods purchase apparatus 100 transmits the user information to the server 500 and receives ID information from the server 500 and then, the user enters into the entrance zone while holding the goods purchase apparatus 100 and passes through the gate 22, the goods purchase apparatus 100 may transmit the user information or the ID information to the entry authentication apparatus 22. Further, the entry authentication apparatus 22 may transmit the user information of the ID information to the server 500. Thereby, the server 500 may recognize that the corresponding user enters into the mart 50.

If a mart related application is installed in the user's mobile terminal 600, when the user passes through the gate 22, the mart related application installed in the user's mobile terminal 600 may be executed or activated by a signal from the entry authentication apparatus 22 and user information may be transmitted to the entry authentication apparatus 22 or the server 500. After the user 10a passes through the entrance zone 20 of the mart 50 and enters into the mart 50, the user 10a may move to a shopping zone 40 and perform shopping. Then, after shopping has been completed, the user 10a may move to a counter zone 30 and perform calculation of purchased goods.

The shopping zone 40 may include a theme zone and a variety zone.

In the theme zone, goods display stands are divided into various packages according to brands or prices and various promotions, such as a customized package or a recommended package, may be carried out. The goods display stand may include information display units 90 displaying price information of respective goods together with the goods. The information display unit 90 may include barcode images, QR code images, etc., including price information.

The information display unit 90 may be implemented as a display device and display various pieces of information, such as product name information, expiration date information, and similar goods information, in addition to the price information.

The user may purchase respective goods arranged on the goods display stand using the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100. That is, if the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image, etc., corresponding goods may be added to a purchase list.

Goods purchase list information acquired by purchasing goods may be processed by the goods purchase apparatus 100 and transmitted to the user's mobile terminal 600 interlocked with the goods purchase apparatus 100 or be transmitted to the server 500 operated by a mart operator. Whenever the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image, the number of goods desired to purchase may be increased.

If the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image and then a user's voice indicating the purchase number of goods is input through an audio input unit 185 (in FIG. 10), the purchase number of the corresponding goods may be determined.

If the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image for a designated time or more, purchase of corresponding goods may be canceled.

For example, if the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image for 5 seconds or more, purchase of corresponding goods may be canceled.

Further, if the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image and then a user's voice indicating the purchase cancellation number of goods is input through the audio input unit 185 (in FIG. 10), the purchase cancellation number of the corresponding goods may be determined.

In the variety zone, online mall goods information may be confirmed and a customer information-based customized advertisement and promotion may be performed. In the variety zone, in addition to goods display stands, digital signages 200, on which online information, customer-based information, and promotion information are displayed, may be provided.

The digital signage 200 is an image display device which may display various goods images and at least one of mart provided price information, online mall price information, similar goods information, customer-based recommended goods information and mart provided promotion information thereof.

Further, the digital signage 200 may display images of goods, which are not displayed in the goods display stand, together with various pieces of information. The digital signage 200 may provide images and various pieces of information of various goods and thus reduce the actual size of the goods display stand.

Since the overall area of the mart 50 may be reduced through such a digital signage 200, a mart operator may provide a new type of mart, in which online advantages and offline advantages are combined, in a building having a small area at a district with a lot of floating population.

Further, since users, who have conveniently ridden in cars and purchased goods at marts, may make a goods purchase list through recognition of barcode images and QR code images of goods and goods corresponding the goods purchase list may be delivered to homes, the users may conveniently perform shopping during working hours or lunch breaks on weekdays rather than on weekends or at night.

The digital signage 200 may display barcode images and QR code images of goods together with goods images. Therefore, if the image capture unit 120 (in FIG. 10) of the goods purchase apparatus 100 recognizes a barcode image or a QR code image, corresponding goods may be added to the goods purchase list.

Further, the number of goods desired to purchase may be set or purchased goods may be canceled by recognizing a barcode image or a QR code image or recognizing a user's voice through the goods purchase apparatus 100.

When a user moves within the shopping zone 40, for example, within the variety zone, user customized goods information according to user's position information may be provided. If the user is located at a first goods display stand, the digital signage 200 located adjacent to the first goods display stand may provide information of goods promoted by the mart operator or preferred by users, among various goods located in the first goods display stand.

Here, the goods information may include at least one of price information at the corresponding mart 50, goods kind information, goods manufacturing date information, price information at other marts or online shopping malls.

The position information of the user 10c may be acquired through a plurality of AP apparatuses 70 arranged in the mart 50. The goods purchase apparatus 100 may be connected to the plurality of AP apparatuses 70 arranged in the mart 50 so as to communicate with the server 50. The server 500 may receive position information, connection information, etc. from the AP apparatus 70 connected to the goods purchase apparatus 70 among the plurality of AP apparatuses 70 and acquire the position of the user based on the received position information, connection information, etc.

Further, in response to the acquired position, the server 500 transmits goods information to be provided to the user to the digital signage 200 adjacent to the position of the user through the AP apparatuses 700. Thereby, the digital signage 200 may display user customized goods information received from the server 500.

When the user performs goods purchase in the shopping zone 40, the user may directly select goods to be carried by the user from the goods display stand and thus add the goods to the purchase list, and may only add goods to be delivered to the purchase list.

After purchase of goods has been completed, the user 10d may move to the counter zone.

The user 10d may directly perform payment for purchased goods on a self checkout counter or perform payment for purchased goods on a helper counter through a helper.

For example, the goods purchase list may be transmitted from the goods purchase apparatus 100 carried by the user, the user's mobile terminal 600, or the server 500 to the calculation apparatus 32 located on the self checkout counter or the helper counter through wireless communication between the goods purchase apparatus 100, the mobile terminal 600 or a membership card possessed by the user, and the calculation apparatus 32, and payment for the purchased goods may be performed by the calculation apparatus 32.

Here, the goods purchase list may be displayed by the calculation apparatus 32 and the user may perform purchase decision/cancellation by purchase decision/cancellation input.

Otherwise, if a image to divide goods into goods to be delivered to home and goods to be directly carried by the user is displayed by the calculation apparatus 32, the goods to be delivered and the goods to be directly carried may be divided from each other by user input.

Here, goods to be directly carried, which are set in advance, have been contained in a cart but goods to be directly carried, which are determined additionally, may be moved from the shopping zone 40 or a storehouse (not shown) to the counter zone 30 with the aid of mart staff. Thereby, shopping desired by the user may be performed.

Particularly, in case of fresh foods, in order to maintain freshness, the user may receive the fresh foods in the counter zone 30 and thus directly carry the fresh foods, and user convenience may be increased. That is, the user may freely move and only prepare a goods purchase list without a separate cart during shopping and then may receive necessary goods in the counter zone 30.

Differently, if the user exits through the entrance zone 22, payment for purchased goods may be performed through the entry authentication apparatus 22.

If the goods purchase apparatus 100 transmits user information to the server 500 and receives ID information from the server 500 and then the user enters into the entrance zone 22 with the goods purchase apparatus 100 and passes through the gate 22, the goods purchase apparatus 100 may transmit the user information or the ID information to the entry authentication apparatus 22.

For example, if the user exits through the entrance zone 22, the goods purchase apparatus 100 may transmit the user information or the ID information to the entry authentication apparatus 22 and the entry authentication apparatus 22 may transmit the user information or the ID information to the server 500 and receive the goods purchase list of the corresponding user from the server 500.

Then, the entry authentication apparatus 22 may automatically perform payment for the goods purchase list using a membership card, which is set in advance, or the mobile terminal 600.

Thereby, payment for purchased goods may be carried out in the entrance zone 22 rather than the counter zone.

Further, purchase decision/cancellation and division of purchased goods into goods to be delivered and goods to be directly carried may be performed through the entry authentication apparatus 22.

Hereinafter, the goods purchase system 10 in accordance with one embodiment of the present invention will be described in more detail with reference to FIG. 2.

FIG. 2 is a view illustrating a goods purchase flow at the mart of FIG. 1.

With reference to FIG. 2, when a user 10 moves and passes through the entrance zone 22 of the mart 50, user authentication is performed through the entry authentication apparatus 22. Here, the user may pick up the goods purchase apparatus 100 to purchase goods.

Then, if the user holding the goods purchase apparatus 100 moves to the shopping zone 40, the user may select goods to be purchased and generate a goods purchase list using the goods purchase apparatus 100.

Thereafter, if the user enters into the counter zone 30, payment for the goods purchase list may be performed through communication between the goods purchase apparatus 100 and the calculation apparatus 32 in the counter zone 30. At this time, the user may finally divide the purchased goods into goods to be directly carried and goods to be delivered. Thereby, the goods selected to be directly carried, such as fresh foods, may be directly carried by the user and the goods to be delivered may be delivered to a delivery place by a vehicle provided by the mart. Since such a goods purchase system 10 may reduce the overall area of the mart 50 through the digital signage 200, a mart operator may provide a new type of mart, in which online advantages and offline advantages are combined, in a building having a small area at a district with a lot of floating population.

Further, since users, who have conveniently ridden in cars and purchased goods at marts, may make a goods purchase list through recognition of barcode images and QR code images of goods through the goods purchase apparatus 100 and goods corresponding to the good purchase list may be delivered to desired delivery places (for example, homes), the users may conveniently perform shopping during working hours or lunch breaks on weekdays rather than on weekends or at night.

FIG. 3 is a view exemplarily illustrating use of the entrance zone of FIG. 1 by users.

FIG. 3 exemplarily illustrates that a first user 10f enters into the mart through the entrance zone 20 and a second user 10e exits the mart through the entrance zone 20.

As one example, if the first user 10f picks up one of a plurality of goods purchase apparatuses 100 arranged around the entrance zone 20 and scans his/her membership card or a barcode image in a mart related application in the mobile terminal 600 using the goods purchase apparatus 100, the goods purchase apparatus 100 may transmit the scanned image to the server 500 to perform user information authentication. Then, the server 500 may assign a unique ID corresponding to the first user 10f to the corresponding goods purchase apparatus 100 and thus distinguish the corresponding goods purchase apparatus 100 from other goods purchase apparatuses 100.

Otherwise, if the first user 10f picks up one of a plurality of goods purchase apparatuses 100 arranged around the entrance zone 20 and tags the goods purchase apparatus 100 with his/her membership card or mobile terminal 600, the goods purchase apparatus 100 may receive user information of the first user 10f through RFID or NFC communication and transmit the received user information to the server 500. Then, the server 500 may assign a unique ID corresponding to the first user 10f to the corresponding goods purchase apparatus 100 and thus distinguish the corresponding goods purchase apparatus 100 from other goods purchase apparatuses 100.

Further, if the first user 10f passes through the entrance zone 20 while holding the goods purchase apparatus 100, the entry authentication apparatus 22 located within the entrance zone 20 may receive the unique ID information assigned to the goods purchase apparatus 100 through communication with the goods purchase apparatus 100 and transmit the received unique ID information to the server 500. Thereby, the server 500 may recognize entry of the first user 10f into the mart.

As another example, if the first user 10f passes through the entrance zone 20 while holding user's membership card or mobile terminal 600, the entry authentication apparatus 22 located within the entrance zone 20 may receive the user information of the first user 10f through RFID or NFC communication with the user's membership card or mobile terminal 600 and transmit the received user information to the server 500. Thereby, the server 500 may recognize entry of the first user 10f into the mart.

If the second user 10e holding a goods purchase apparatus 100 exits the mart through the entrance zone 20, the server 500 may recognize exit of the second user 10e to the outside of the mart.

Otherwise, if the second user 10e holding the goods purchase apparatus 100 exits the mart through the entrance zone 20, the goods purchase apparatus 100 may transmit a unique ID to the entry authentication apparatus 22 and the entry authentication apparatus 22 may receive a goods purchase list of the second user 10e, stored in the server 500, from the server 500.

The entry authentication apparatus 22 may automatically perform payment for goods based on the received goods purchase list.

For example, the entry authentication apparatus 22 may select the user's membership card or mobile terminal 600 as a payment method and automatically perform payment if the second user 10e exits the mart through the entrance zone 20.

That is, automatic personal authentication related to a point of sales (POS) system may be performed and purchase or payment interlocking with the mobile terminal may be performed through the entrance zone 20.

If a user frequently using online shopping malls enters into the mart through the entrance zone 20, separate information specialized for the corresponding user may be provided to the user through the entry authentication apparatus 22.

FIG. 4A is a view exemplarily illustrating the theme zone in the shopping zone of FIG. 1 and FIG. 4B is a view exemplarily illustrating the variety zone in the shopping zone of FIG. 1.

First, in the theme zone of FIG. 4A, goods display stands are divided into various packages according to brands or prices and various promotions, such as a customized package or a recommended package, may be carried out.

Goods display stands in which goods are displayed and information display units 90 displaying price information may be provided within the theme zone. The information display unit 90 may include barcode images and QR code images including price information.

The information display unit 90 may be implemented as a display device and a user may confirm information related to goods arranged in the theme zone by operation of the information display unit 90.

Further, in the variety zone of FIG. 4B, online mall goods information may be confirmed and customer information-based customized advertisement and promotion may be performed. In the variety zone, in addition to goods display stands, digital signages 200 in which online information, customer-based information, and promotion information are displayed may be provided.

Further, since users, who have conveniently ridden in cars and purchased goods at marts, may make a goods purchase list through recognition of barcode images and QR code images of goods and goods corresponding the goods purchase list may be delivered to homes, the users may conveniently perform shopping during working hours or lunch breaks on weekdays rather than on weekends or at night.

The digital signage 200 may include a transparent display. Thereby, various pieces of information including price information may be displayed on the transparent display under the condition that actual goods are displayed in a showcase.

Further, the digital signage 200 may include an image projection module. When a projected image is displayed on a screen through the image projection module, goods images and various pieces of information may be displayed even on a free-form surface.

The image projection module may output both visible light and infrared light and the goods purchase apparatus 100 may recognize infrared light so that corresponding goods may be added to a purchase list. Otherwise, the image projection module may recognize the position of the goods purchase apparatus 100 through infrared light, determine goods which a user desires to purchase based on the position, and transmits the determined goods information to the goods purchase apparatus 100.

FIG. 5A is a view exemplarily illustrating a self checkout counter in the counter zone of FIG. 1 and FIG. 5B is a view exemplarily illustrating a helper counter in the counter zone of FIG. 1.

A self checkout counter 32a of FIG. 5A is one example of the calculation apparatus 32 of FIG. 1 and may include a touch type monitor 500a which is horizontally disposed.

For example, if tagging of the monitor 500a with the goods purchase apparatus 100 held by a user 10g is performed, the self checkout counter 32a may recognize the user 10g holding the goods purchase apparatus 100 and receive a list of goods purchased by the user 10g from the server 500, the user's mobile terminal 600, or the goods purchase apparatus 100.

Then, the monitor 500a may display the list of goods purchased by the user 10g. In addition to the goods list, the monitor 500a may further display a purchase decision/cancellation item and a delivery/direct carriage item.

Further, the user 10g may perform purchase decision/cancellation or delivery/direct carriage in the goods list displayed on the monitor 500a through touch input.

A user's membership card or mobile terminal may be used as a payment means, and an authentication procedure for identifying the user 10g may be further required during payment.

In accordance with the method of using the self checkout counter 32a of FIG. 5A, sales promotion may be carried out due to reduction in a waiting time during payment and exposure of similar product advertisements.

A helper counter 32b of FIG. 5B is another example of the calculation apparatus 32 of FIG. 1 and may include a touch type monitor 500b which is vertically disposed. The helper counter 32b requires a separate cashier 11.

If the cashier 11 or a user 10h performs tagging of the monitor 500b with the goods purchase apparatus 100, the helper counter 32b may recognize the user 10h of the goods purchase apparatus 100 and receive a list of goods purchased by the user 10h from the server 500, the user's mobile terminal 600, or the goods purchase apparatus 100.

Then, the monitor 500b may display the list of goods purchased by the user 10g. In addition to the goods list, the monitor 500b may further display a purchase decision/cancellation item and a delivery/direct carriage item.

Further, the user 10h may perform purchase decision/cancellation or delivery/direct carriage in the goods list displayed on the monitor 500a through touch input.

FIG. 6 is a view illustrating a goods purchase and delivery flow.

With reference to FIG. 6, if tagging of the goods purchase apparatus 100 with a user's membership card 85 is performed (Operation S1), the goods purchase apparatus 100 receives user information from the membership card 85 and transmits the user information to the mart server 500 through the AP apparatus 700 (Operation S2).

Then, the server 500 performs matching between user information stored in a storage unit (not shown) and the received user information (Operation S3). Thereafter, the server 500 performs user authentication. Thereafter, the server 500 may assign ID information to the goods purchase apparatus 100 and transmit the ID information to the goods purchase apparatus 100.

If a user enters into the shopping zone and scans information of goods desired to purchase among goods in the mart using the goods purchase apparatus 100, the goods desired to purchase are added and thus, a goods purchase list is made. The made goods purchase list is transmitted to the server 500 through the goods purchase apparatus 100, and the server 500 stores the goods purchase list.

If the user enters into the counter zone and tags the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter with the goods purchase apparatus 100 or tags the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter with the user's membership card 85 (Operation S4), the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter requests the server 500 to transmit the goods purchase list of the corresponding user and the server 500 transmits the goods purchase list to the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter (Operation S5). Then, the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter displays the received goods purchase list and performs a payment procedure using the received goods purchase list and the user's membership card 85.

After payment has been completed, the monitor 500a of the purchased goods calculation apparatus 32a disposed on the counter requests the server 500 to deliver purchased the goods (Operation S7) and the server 500 transmits a request for delivery of the purchased goods to a head office server 510.

The head office server 510 transmits the request for delivery of purchased goods to a warehouse 99 (Operation S8) and the warehouse 99 loads the purchased goods on a delivery vehicle 99 and performs delivery.

FIG. 21 is a view exemplarily illustrating the concept of a digital signage having an image projection module in accordance with one embodiment of the present invention.

With reference to FIG. 21, the digital signage 200 may include an image projection module 1100 and a screen 1200.

The image projection module 1100 may output a projected image based on visible light to the outside.

Further, the image projection module 110 may output light to detect a distance from an external target object to the outside through first direction scanning and second direction scanning, receive light corresponding to the output light, and detect the distance from the external target object or the movement of the external target object based on the output light and the received light. Here, the output light may be infrared light.

The image projection module 1100 may output both the projected image based on visible light and the output light to the outside. For this purpose, the image projection module 100 may include a 2D scanner outputting the projected image based on visible light together with the output light to the outside by a scanning method through first direction scanning and second direction scanning.

Since a user 10m located at the opposite side to the image projection module 1100 recognizes an image projected on the screen 1200, such a method may be referred to as a rear projection method.

Since the images of various goods provided by the mart 500 are displayed as the projected image, the user 10m may recognize information regarding the various goods.

Detection of a distance from the user 10m located in front of the screen 1200 may be performed based on light output in the direction of the screen 1200.

As one example, if the user 10m located in front of the screen 1200 performs touch input, i.e., touches the screen 1200, using a finger, as exemplarily shown in FIG. 21, the image projection module 1100 may receive light scattered or reflected by the user's finger and sense the touch input based on the output light and the received light.

As another example, if the user 10m located in front of the screen 1200 performs gesture input to the screen 1200 using a user's hand, as exemplarily shown in FIG. 21, the image projection module 1100 may receive light scattered or reflected by the user's hand and sense the gesture input based on the output light and the received light.

The digital signage 200 including the image projection module 1100 in accordance with the embodiment of the present invention may output images of respective goods as a projected image based on visible light, output light to detect touch input or gesture input, and sense the touch input or the gesture input.

For example, the image projection module 1100 in the digital signage 200 outputs images of respective goods as a projected image based on visible light and calculates position information of touch input using the goods purchase apparatus 100 or gesture input using the goods purchase apparatus 100, performed around one goods image among a plurality of goods images. Thereby, the digital signage 200 may decide purchase of one of the plural goods and transmit the purchase decision information to the goods purchase apparatus 100 held by the user 10m. Then, the goods purchase apparatus 100 may transmit the purchase decision information to the server 500. Otherwise, the digital signage 200 including the image projection module 1100 in accordance with the embodiment of the present invention may output images of respective goods as a projected image based on visible light and output light as information of the respective goods. When the user 10m brings the goods purchase apparatus 100 close to one goods image among a plurality of goods images displayed on the digital signage 200, the digital signage 200 may receive output light (infrared light) outputting information of the corresponding goods. Then, the goods purchase apparatus 100 decides purchase of the corresponding goods based on the received output light. After decision of purchase of the corresponding goods, the goods purchase apparatus 100 may transmit purchase information to the server 500.

FIG. 22 is one exemplary block diagram briefly illustrating the inside of the image projection module of FIG. 21.

With reference to FIG. 22, the image projection module 1100 may output a projected image and output light using a time of flight (TOF) method.

For this purse, the image projection module 1100 may include a memory 1120, a scanner 1140, a processor 1170, a communication module 1180, a driving unit 1185, a power supply unit 1190, a light source unit 1210, and a light detection unit 1280.

The memory 1120 may store a program for processing or control through the processor 1170 and perform a function to temporarily store input or output data (for example, a moving image, a still image, etc.).

The communication module 1135 serves as an interface with all external devices connected to the image projection module 1100 by wire or wirelessly. The communication module 1135 may receive data or power transmitted or supplied from these external devices, transmit the received data or power to the respective elements of the image projection module 1100, and transmit data within the image projection module 110 to the external devices.

Particularly, the communication module 1135 may receive a wireless signal from an adjacent mobile terminal (not shown). Here, the wireless signal may include various types of data including a voice call signal, a video phone call signal, text data, and image data.

The scanner 1140 may sequentially and repeatedly perform first direction scanning and second direction scanning of input light and then output light to the outside.

Light input to the scanner 1140 may include visible light corresponding to a projected image and output light for distance detection of an external target object. Here, the output light may be infrared light.

The scanner 1140 may perform scanning of the overall external scan region in the unit of a frame while sequentially and repeatedly performing scanning in a direction from left to right and scanning in a direction from right to left in the external scan region. Further, the scanner 1140 may output a projected image based on visible light and output light to the external scan region through such scanning.

The processor 1170 may perform overall control operation of the image projection module 1100.

In more detail, the processor 1170 may control operations of the respective units of the image projection module 1100.

The processor 1170 may control output of a video image related to goods images or goods information stored in the memory 1120 or a video image related to goods images or foods information received from the server 500 through the communication module 1135 as a projected image.

For this purpose, the processor 1170 may control the driving unit 1185 controlling the light source unit 1210 outputting visible light including red (R), green(G), and blue (B) light. In more detail, the processor 1170 may output R, G, and B signals corresponding to a video image to be displayed to the driving unit 1185.

In order to detect a distance from an external target object, the processor 1170 may transmit an electrical signal corresponding to output light to the driving unit 1185.

The processor 1170 may control operation of the scanner 1140. In more detail, the processor 170 may output a projected image and output image to the outside by sequentially and repeatedly performing first direction scanning and second direction scanning.

The processor 1170 may vary a frame rate and thus vary a scanning speed of the scanner 1140 when the processor 1170 controls operation of the scanner 1140.

The processor 1170 may perform detection of a distance from an external target object based on an electrical signal corresponding to output light transmitted to the driving unit 1185 and an electrical signal corresponding to light received by the light detection unit 1280.

For example, the processor 1170 may detect a distance from the external scan region using a phase difference between the electrical signal corresponding to the output light and the electrical signal corresponding to the received light. Further, the processor 1170 may detect a user's gesture motion based on distance information of the external scan region detected in the unit of a frame.

In more detail, the processor 1170 may cause the screen 1200 to have first transparency during a first frame section and process touch input during the first frame section, and cause the screen 50 to have second transparency lower than the first transparency during a second frame section and process gesture input during the second frame section.

Further, the processor 1170 may control a screen controller 1205 controlling the screen 1200 at the outside of the image projection module 1100.

The screen 1200 may have the first transparency during the first frame section and have the second transparency lower than the first transparency during the second frame section. In more detail, the screen 1200 becomes opaque during the first frame section so that a projected image may be displayed on the screen 1200, and the screen 1200 becomes transparent during the second frame section so that output light may pass through the screen 1200 and a user located in front of the screen 1200 may be detected.

Such adjustment of transparency of the screen 1200 according to frame sections may be performed by the screen controller 1205.

If the screen 1200 includes a first transparent electrode and a second transparent electrode intersecting each other and an anisotropic substance disposed between the first transparent electrode and the second transparent electrode, the screen controller 1205 may vary the alignment direction of the anisotropic substance according to power applied between the first transparent electrode and the second transparent electrode and thus control the screen 1200 to have first transparency during the first frame section and to have second transparency during the second frame section.

A frame synchronization signal may be transmitted from the processor 1170 to the screen controller 1205.

The light source unit 1210 may include a blue light source unit outputting blue light, a green light source unit outputting green light, and a red light source unit outputting red light. The respective light source units may be implemented as laser diodes. Otherwise, the respective light source units may be implemented as LEDs.

Further, the light source unit 1210 may include an infrared light source unit outputting infrared light.

The light detection unit 1280 may convert light received from the outside into an electrical signal corresponding to output light. For this purpose, the light detection unit 1280 may include photodiodes converting an optical signal into a reception signal, i.e., an electrical signal.

If infrared light is output as output light, in order to receive infrared light as received light, the light detection unit 1280 may include a charge coupled device (CCD) or a CMOS sensor.

Although not shown in FIG. 22, a sampler (not shown) converting an analog signal into a digital signal may be further provided between the light detection unit 1280 and the processor 1170.

The driving unit 1185 may control the red light source unit, the green light source unit, and the blue light source unit within the light source unit 1210 to output red light, green light, and blue light, in response to R, G, and B signals received from the processor 1170.

The driving unit 1185 may control the infrared light source unit within the light source unit 1210 to output infrared light in response to output light received from the processor 1170.

The power supply unit 1190 may receive external power or internal power under control of the controller 1170 and supply power required to operate the respective elements of the image projection module 1100.

FIG. 23 is a view illustrating simultaneous output of a projected image and light for distance detection from the image projection module of FIG. 21.

With reference to FIG. 23, the scanner 1140 within the image projection module 1100 in accordance with the embodiment of the present invention may sequentially and repeatedly perform first direction scanning and second direction scanning of input light and output light to the external scan region. FIG. 23 exemplarily illustrates that a projected image 1202a and output light IR are output through the screen 1200.

The scanner 1140 within the image projection module 1100 in accordance with the embodiment of the present invention may simultaneously output a projected image based on input visible light (RGB) and infrared light (IR) as output light. Particularly, the scanner 1140 may perform scanning of the overall external scan region in the unit of a frame while sequentially and repeatedly performing scanning in a direction from left to right and scanning in a direction from right to left in the external scan region.

That is, the image projection module 1100 in accordance with the embodiment of the present invention may detect a distance from an external target object while projecting an image toward the outside and thus, display a related image based on the distance from the object or movement of the object or display an image corresponding to a user's gesture.

Hereinafter, the inside of the image projection module 1100 will be described in more detail.

FIGS. 24A and 24B are views illustrating sensing of touch input and gesture input by the image projection module of FIG. 21.

Image projection modules 1100a of FIGS. 24A and 24B are the same and may include a light source unit 1210, an optical condensation unit 1212, an optical unification unit 1210, an optical reflection unit 1256, a scanner 1140, a processor 1170, a driving unit 1185, an optical condensation unit 1218, an infrared transmission filter 1281, and a light detection unit 1280.

The light source unit 1210 may include a plurality of light source units. That is, the light source unit 1210 may include a red light source unit 1210R, a green light source unit 1210G, a blue light source unit 1210B, and an output light source unit 12101R outputting infrared light as output light. The red, green, and blue light source units 1210R, 1210G, and 1210B may include laser diodes.

The respective light source units 1210R, 1210G, 1210B, 12101R may be operated by respective electrical signals from the driving unit 1185, and these electrical signals may be generated under control of the processor 1170. The output light source unit 12101R may output light by an electrical signal corresponding to the output light.

Light output from the respective light source units 1210R, 1210G, 1210B, 12101R is collimated through respective collimator lenses within the optical condensation unit 1212.

The optical unification unit 1220 unifies light output from the respective light source units 1210R, 1210G, 1210B, 12101R and outputs the light in one direction. For this purpose, the optical unification unit 1220 may include four 2D MEMS mirrors 1220a, 1220b, 1220c, and 1220d.

That is, the first optical unification unit 1220a, the second optical unification unit 1220b, the third optical unification unit 1220c, and the fourth optical unification unit 1220d output red light output from the red light source unit 1210R, green light output from the green light source unit 1210G, blue light output from the blue light source unit 1210B, and output light output from the output light source unit 12101R, in the direction of the scanner 1140.

The optical reflection unit 1256 reflects the red light, the green light, the blue light, and the output light, having passed through the optical unification unit 1220, in the direction of the scanner 1140. The optical reflection unit 1256 may reflect light of various wavelengths and, for this purpose, be implemented as a total mirror (TM).

The scanner 1140 may receive visible light (RGB) and output light (IR) from the light source unit 1210 and sequentially and repeatedly perform first direction scanning and second direction scanning to the outside. Such a scanning operation may be repeatedly performed over the entirety of the external scan region. Particularly, the visible light (RGB) and the output light (IR) output from the scanner 110 may be output to the screen 1200.

Thereby, a projected image corresponding to the visible light (RGB) may be displayed on the screen 1200.

Since a user located at the opposite side to the image projection module 1100 recognizes an image projected on the screen 1200, such a method may be referred to as a rear projection method.

Detection of a distance from the user located in front of the screen 1200 may be performed based on the output light output to the screen 1200.

In detail, the image projection module senses touch input by a user's finger 1020 touching the screen 1200 during the first frame section and senses gesture input based on movement of a user's hand 1060 located at the opposite side of the screen 1200 during the second frame section.

For this purpose, the screen 1200 may become opaque during the first frame section and become transparent during the second frame section.

FIG. 24A exemplarily illustrates that the screen 1200 becomes opaque during the first frame section. At this time, the image projection module 1100 may output both a projected image (RGB) by visible light and output light (IR). If the user performs touch input on the screen 1200 by moving a user's finger 1020, the output light (IR) may be scattered or reflected by the user's finger 1020 and thus, received light may be incident upon the image projection module 1100. In more detail, the received light may be input to the light detection unit 1280 via the optical condensation unit 1218 and the infrared transmission filter 1282.

The light detection unit 1280 may convert such received light into an electrical signal, and the processor 1170 may perform distance detection and touch input processing based on the received light by the user's finger 1020 and the output light.

FIG. 24B exemplarily illustrates that the screen 1200 becomes transparent during the second frame section. At this time, the image projection module 1100 may output light (IR).

Otherwise, the image projection module 1100 may output both a projected image (RGB) by visible light and output light (IR). If the user performs gesture input in front of the screen 1200 by moving a user's hand 1060, the output light (IR) may be scattered or reflected by the user's hand 1060 and thus, received light may be incident upon the image projection module 1100. In more detail, the received light may be input to the light detection unit 1280 via the optical condensation unit 1218 and the infrared transmission filter 1282.

The light detection unit 1280 may convert such received light into an electrical signal, and the processor 1170 may perform distance detection and gesture input processing based on the received light by the user's hand 1060 and the output light.

The first frame section and the second frame section may be alternately disposed. However, the first frame section and the second frame section are limited thereto and disposition of the first frame section and the second frame section may be variously modified.

In accordance with the embodiment of the present invention, since the scanner 1140 outputs visible light (RGB), although the screen 1200 on which a projected image is displayed has a free-form surface, the projected image may be displayed so as to correspond to the free-form surface of the corresponding screen 1200. For example, the curved surface state of the screen 1200 may be detected through distance detection due to output light, scaling of a displayed image corresponding to the curved surface is performed, and the scaled projected image may be displayed. Thereby, a free-form surface display may be implemented.

FIGS. 25A(a), 25A(b), and 25B are views illustrating a distance detection method in the image projection module of FIGS. 24A and 24B.

First, FIGS. 25A(a) and 25A(b) are views illustrating sensing of touch input on the screen 1200 of FIG. 24A during the first frame section.

If a user touches a first point P1 on the screen 1200 under the condition that light is output to the screen 1200, for example, using a user's hand, as exemplarily shown in FIG. 25A(a), the output light is scattered or reflected by the user's hand and is received by the light detection unit 1280.

FIG. 25A(a) exemplarily illustrates that the amplitudes of the received light at x and y coordinates corresponding to the first point P1 are increased.

FIG. 25A(b) exemplarily illustrates an electrical signal (Tx) of the output light and an electrical signal (Rx) of the received light, particularly, the amplitudes (Ae) of the received light at x and y coordinates corresponding to the first point P1. That is, the amplitude of the electrical signal of received light at a point touched by the user is higher than that of electrical signals at other points on the screen.

Using such characteristics, the processor 1170 may detect and process a touch point on the screen 1200. Particularly, the processor 1170 may calculate coordinates of touch input if the screen 1200 has first transparency.

Next, FIG. 25b is a view illustrating sensing of gesture input performed in front of the screen 1200 of FIG. 24B during the second frame section.

Here, Tx represents an electrical signal of output light, and Rx represents an electrical signal of received light by a user's gesture in front of the screen 1200.

If the screen transmits output light, output light according to input of a gesture of a user's hand 1060 located in front of the screen 1200 may be received by the image projection module 1100. Further, the processor 1170 may calculate distance information according to a phase difference Φ between the electrical signal of the output light and the electrical signal of the received light and process the gesture input based on the distance information.

The block diagram of the inside of the above-described purchased goods calculation apparatus 32 may be the same as the block diagram of the inside of the digital signage of FIG. 20.

Hereinafter, among the respective elements of the purchased goods calculation apparatus 32, only the elements differing from the elements of the digital signage will be described.

The communication unit (not shown) may exchange data with the membership card, the goods purchase apparatus 100 or the mobile terminal 600 which the user possesses, or the server 500 through a wireless method. For example, the communication unit (not shown) may receive user information by wireless communication, such as NFC communication, based tagging with the membership card, the goods purchase apparatus 100 or the mobile terminal 600 which the user possesses and receive a purchase list of goods purchased by the user by connection to the server 500 according to reception of the user information.

The processor (not shown) controls overall operation of the respective units within the purchased goods calculation apparatus 32.

Particularly, if the communication unit (not shown) may receive user information by wireless communication, such as NFC communication, based tagging with the membership card, the goods purchase apparatus 100 or the mobile terminal 600 which the user possesses, the processor (not shown) may control the communication unit (not shown) so as to receive the purchase list of goods purchased by the user from the server 500.

Further, the processor (not shown) may perform payment according to user input of selection of a payment method. The processor (not shown) may transmit a payment request signal to the server 500 using card information which has been registered in advance.

Further, the processor (not shown) may control the display (not shown) so as to display a image to divide the purchased goods into goods to be delivered to home and goods to be directly carried by hand, before payment.

For example, the processor (not shown) may transmit information of the goods to be directly carried to the server 500 and thus, may notify the server 500 of information of the goods to be directly carried. Further, the processor (not shown) may control receipt of the corresponding goods in the counter zone 30.

The operating method of the goods purchase apparatus of the present invention may be implemented as code readable by the processor provided in the display apparatus for vehicles in a recording medium readable by the processor. The recording medium readable by the processor may be any kind of recording device in which data readable by the processor are stored. For example, the recording medium readable by the processor may include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage medium, or a carrier wave, such as data transmission over the Internet. Further, since the recording medium readable by the processor may be distributed in a computer system connected through a network, code readable by the processor in a distributed manner may be stored and executed.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
