DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Certain exemplary embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings.
In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the invention. Thus, it is apparent that the exemplary embodiments of the present invention can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention with unnecessary detail.
FIG. 1 is a block diagram of a vending machine 100 according to a first exemplary embodiment of the present invention. The vending machine 100 of FIG. 1 generates and displays a menu screen set according to users' personal characteristics, so that a user can select a desired product from the menu screen. Additionally, the vending machine 100 may generate and display an information providing screen or an advertisement screen according to the users' personal characteristics, in order to induce the user to buy products.
The vending machine 100 of FIG. 1 includes an external signal input unit 110, a storage unit 120, a control unit 130, a graphical user interface (GUI) generating unit 140 and a touch screen 150.
The external signal input unit 110 is communicably connected to external devices, and thus receives external input images stored in the connected external devices. For example, the external signal input unit 110 may be an interface to receive information matching the user characteristics, so the external signal input unit 110 may be connected to a server via the Internet and may receive information, such as news or weather reports. The external signal input unit 110 includes a terminal to be connected to the external devices.
The storage unit 120 stores programs required for the control unit 130 to control operations of the vending machine 100. Additionally, the storage unit 120 stores the menu screen set according to users' personal characteristics and the advertisement screen.
While the information providing screen is received by the external signal input unit 110 and the menu screen and advertisement screen are received by the storage unit 120 in the first exemplary embodiment of the present invention, there is no limitation thereto. Accordingly, the present invention is also applicable to a situation in which the menu screen is received by the external signal input unit 110.
The GUI generating unit 140 generates a GUI representing the menu screen, and displays the generated GUI on the touch screen 150. The operation by which the GUI generating unit 140 generates the GUI is controlled by the control unit 130.
The touch screen 150 displays an image to which the GUI output from the GUI generating unit 140 is added. The image may include a menu screen, advertisement screen and information providing screen.
The menu screen shows a plurality of GUIs indicating a plurality of products stored in a product storage unit (not shown) of the vending machine 100. For example, if beverages, such as cola drinks, citrus-flavored beverages or coffee are stored in the product storage unit (not shown), a menu screen comprising at least one of a GUI indicating cola drinks, a GUI indicating citrus-flavored beverages and a GUI indicating coffee may be displayed on the touch screen 150.
The advertisement screen may be used to advertise products stored in the product storage unit (not shown) of the vending machine 100 in order to induce users to buy the products, or may be used to advertise products other than the products stored in the product storage unit (not shown) or services in order to create advertising revenue.
The information providing screen functions to provide information, such as news or weather reports. A display of such an information providing screen may attract users' attention and may ultimately induce users to buy products.
The touch screen 150 functions to receive user operating commands input by a touch or dragging operation.
The control unit 130 controls the GUI generating unit 140 to generate and display a GUI in response to a user operating command input via the touch screen 150 or other manipulating means (not shown). Additionally, the control unit 130 collects user characteristic information input via the touch screen 150 and causes the touch screen 150 to display an image corresponding to the collected information.
Specifically, the control unit 130 collects location information regarding a part of the touch screen 150 touched by the user, and controls the GUI generating unit 140 and touch screen 150 so that a menu screen is generated based on the collected location information and the generated menu screen is displayed.
Hereinafter, a process of collecting location information on a touched part of the touch screen 150 and displaying a menu screen will be described in detail with reference to FIGS. 2 and 3.
FIG. 2 illustrates the vending machine 100 on which a menu screen 200 is displayed according to the first exemplary embodiment of the present invention, and FIG. 3 is a flowchart illustrating a process of displaying the menu screen 200 according to the first exemplary embodiment of the present invention.
In FIG. 2, the large-scale touch screen 150 is disposed on the front of the vending machine 100. The vending machine 100 collects location information regarding a part of the touch screen 150 touched by the user as user characteristic information. The control unit 130 causes the menu screen 200 to be displayed based on the collected location information.
The control unit 130 determines whether the user touches the touch screen 150 (S210). If it is determined that the user has not touched the touch screen 150 (S210-N), the control unit 130 causes the information providing screen or advertisement screen to be displayed on the touch screen 150 (S260).
If it is determined that the user has touched the touch screen 150 (S210-Y), the control unit 130 determines whether a height of the touched part is higher or lower than a preset value (S220).
If the user does not touch the touch screen 150, the vending machine 100 may determine that the user does not intend to buy any products, and may then display the information providing screen or advertisement screen to induce the user to buy products. Alternatively, if the user has touched the touch screen 150, the vending machine 100 may determine that the user desires to buy products, and may then display the menu screen 200 so that the user can buy a desired product via the menu screen 200.
If it is determined that the height is higher than the preset value (S220-Y), the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for adults' tastes (S230).
Alternatively, if it is determined that the height is lower than the preset value (S220-N), the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for children's tastes (S240).
For example, if the height is equal to or higher than 150 centimeters (cm), the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for adults' tastes, such as coffee, green tea or cigarettes; and alternatively, if the height is equal to or lower than 150 cm, the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for children's tastes, such as juice or cola drinks.
Accordingly, the control unit 130 estimates the user's age according to the height of the touched part, and then controls the GUI generating unit 140 to generate menu items suitable for the user's estimated age. Here, products such as coffee, green tea, cigarettes, juice or cola drinks, are previously stored in the product storage unit (not shown) of the vending machine 100.
Subsequently, the control unit 130 controls the touch screen 150 so that the menu screen 200 containing the generated menu items is displayed on the touched part of the touch screen 150 (S250).
Thus, the vending machine 100 estimates the user's age and constructs a menu according to whether the height of the touched part is higher or lower than the preset value, so it is possible for the user to buy desired products more easily and simply, and it is possible for a product provider to induce the user to buy products, thereby increasing sales.
Additionally, since the touched part of the touch screen 150 makes it easy for the user to perform input, the vending machine 100 can display the menu screen 200 on the touched part. Accordingly, the user can view the menu screen 200 more conveniently.
The menu screen 200 is displayed differently according to whether products suitable for adults' tastes or children's tastes are determined to be appropriate using a single reference such as the preset value in the exemplary embodiment of the present invention, but there is no limitation thereto. Accordingly, the present invention is also applicable to a situation in which the menu screen 200 is displayed using a plurality of references.
Additionally, while the information providing screen or advertisement screen is displayed when the user does not touch the touch screen 150, as described above, this is merely an example for convenience of description. Accordingly, it is possible to display one of the menu screen 200, information providing screen and advertisement screen according to a set mode, or to display other screens. For example, if the user touches the touch screen 150, the information providing screen or advertisement screen may be displayed in place of the menu screen 200, according to whether the height of the touched part of the touch screen 150 is higher or lower than the preset value. Additionally, if the user touches an upper part of the touch screen 150, news or advertisements suitable for adults' tastes may be displayed, and if the user touches a lower part of the touch screen 150, news or advertisements suitable for children's tastes may be displayed.
Hereinafter, a second exemplary embodiment of the present invention will be described in detail with reference to FIG. 4. FIG. 4 is a block diagram of a vending machine 100 according to the second exemplary embodiment of the present invention.
The vending machine 100 of FIG. 4 includes an external signal input unit 110, a storage unit 120, a control unit 130, a GUI generating unit 140, a display unit 160 and a position sensor 170. Here, the external signal input unit 110, storage unit 120, GUI generating unit 140 and display unit 160 shown in FIG. 4 are similar to or the same as the external signal input unit 110, storage unit 120, GUI generating unit 140 and touch screen 150 shown in FIG. 1, so no further description thereof is required. Only the position sensor 170 and control unit 130 shown in FIG. 4 are described below.
The position sensor 170 collects information on characteristics of a user located within a predetermined distance thereof For example, the position sensor 170 collects information on the height of the user located within the predetermined distance, and transfers the information on the user's height to the control unit 130.
The control unit 130 receives the information on the user's height collected by the position sensor 170 and causes an image corresponding to the received information to be displayed on the display unit 160.
Specifically, the control unit 130 collects the information on the height of a user located within a predetermined distance of the vending machine 100 using the position sensor 170, and controls the GUI generating unit 140 to generate a menu screen 200 based on the information on the user's height and to display the generated menu screen 200.
Hereinafter, a process of collecting information on the user's height and displaying the menu screen 200 will be described in detail with reference to FIGS. 5 and 6.
FIG. 5 illustrates the vending machine 100 on which the menu screen 200 is displayed according to the second exemplary embodiment of the present invention, and FIG. 6 is a flowchart illustrating a process of displaying the menu screen 200 according to the second exemplary embodiment of the present invention.
In FIG. 5, the large-scale display unit 160 is disposed on the front of the vending machine 100, and the position sensor 170 is located on the top of the vending machine 100. The position sensor 170 determines the user's height as user characteristic information. The control unit 130 causes the menu screen 200 to be displayed based on the user's height.
While a single position sensor 170 is disposed on the top of the vending machine 100 in the second exemplary embodiment of the present invention, this is merely an example for convenience of description. Accordingly, the present invention is equally applicable to a situation in which a plurality of position sensors are disposed on areas other than the top of the vending machine 100.
The position sensor 170 determines whether the user comes within a predetermined radius of the vending machine 100 (S310). If it is determined that the user is not located within the predetermined radius (S310-N), the control unit 130 causes the information providing screen or advertisement screen to be displayed on the display unit 160 (S370).
If it is determined that the user is located within the predetermined radius (S310-Y), the position sensor 170 detects the user's height (S320).
If the user does not approach the vending machine 100, the vending machine 100 may determine that the user does not intend to buy products, and may then display the information providing screen or advertisement screen to induce the user to buy products. Alternatively, if the user has approached the vending machine 100, the vending machine 100 may determine that the user desires to buy products, and may then display the menu screen 200 so that the user can buy a desired product via the menu screen 200.
The position sensor 170 determines whether the user is tall or short (S330). If it is determined that the user is tall (S330-Y), the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for adults' tastes (S340).
Alternatively, if it is determined that the user is short (S330-N), the control unit 130 controls the GUI generating unit 140 to generate menu items suitable for children's tastes (S350).
For example, if the user is greater than 150 cm, the control unit 130 may control the GUI generating unit 140 to generate menu items suitable for adults' tastes, such as coffee, green tea or cigarettes; and alternatively, if the user is less than 150 cm, the control unit 130 may control the GUI generating unit 140 to generate menu items suitable for children's tastes, such as juice or cola drinks. Accordingly, the control unit 130 estimates the user's age according to the user's height determined by the position sensor 170, and then controls the GUI generating unit 140 to generate menu items suitable for the user's estimated age.
Subsequently, the control unit 130 controls the menu screen 200 comprising the generated menu items to be displayed on a portion on the display unit 160 corresponding to the user's height (S360). Accordingly, it is possible for the user to select desired menu items from the menu screen 200 more conveniently.
Therefore, the vending machine 100 estimates the user's age and constructs a menu according to whether the user is tall or short, so it is possible for the user to buy desired products more easily and simply and it is also possible for a product provider to induce the user to buy products, thereby increasing sales.
Additionally, the position sensor 170 may collect information regarding horizontal movement of a user located within a predetermined distance of the vending machine 100. FIGS. 7 and 8 exemplarily illustrate a vending machine 100 which detects the horizontal movement of the user and displays the menu screen 200 according to the detected horizontal movement of the user.
In FIG. 7, the position sensor 170 detects the horizontal movement of the user within the predetermined distance of the vending machine 100.
After the position sensor 170 detects the horizontal movement of the user, and transfers information regarding the horizontal movement of the user to the control unit 130, the control unit 130 receives the information regarding the horizontal movement of the user from the position sensor 170, and causes the menu screen 200 to be displayed according to the received information.
For example, if it is determined that the user moves to the right, as shown in FIG. 7, the control unit 130 allows the menu screen 200 to move to the right on the display unit 160 so that the menu screen 200 is displayed according to the user's movement.
Additionally, the control unit 130 controls the form of the menu screen 200 to change according to the horizontal movement of the user. For example, if the user is located in front of the center of the vending machine 100, the menu screen 200 may also be displayed on the center of the vending machine 100. In this situation, as sufficient space exists on the right and left of the display unit 160, the control unit 130 may cause the menu screen 200 to be displayed horizontally. Accordingly, the user is able to select one or more menu items from the menu screen 200 on the same line.
Alternatively, if the user is located at the left of the vending machine 100, the menu screen 200 may also be displayed on the left of the vending machine 100. In this situation, there is not enough space to display the menu screen 200 on the left of the display unit 160, so the control unit 130 may cause the menu screen 200 to be displayed vertically, and the user is thus able to select one or more menu items from the menu screen 200 more conveniently. This is also applicable to a situation in which the user is located at the right of the vending machine 100. However, one of skill in the art would recognize that the menu screen 200 does not necessarily have to be displayed vertically, and may instead be displayed in other ways.
When first, second and third vending machines 100-1, 100-2 and 100-3 are connected to each other in series, as shown in FIG. 8, a menu screen 200-1 shown in FIG. 8 may be displayed according to the horizontal movement of the user, in the same manner as shown in FIG. 7.
In FIG. 8, the first, second and third vending machines 100-1, 100-2 and 100-3 have first, second and third position sensors 170-1, 170-2 and 170-3, respectively, which are able to detect the horizontal movement of the user.
If the first, second and third position sensors 170-1, 170-2 and 170-3 detect the horizontal movement of the user, the control unit 130 receives information regarding the horizontal movement of the user from each of the first, second and third position sensors 170-1, 170-2 and 170-3, and causes the menu screen 200-1 to be displayed on first, second and third display units 160-1, 160-2 and 160-3 according to the horizontal movement of the user.
For example, if the user moves from a location within a predetermined radius of the first position sensor 170-1 to a location within a predetermined radius of the second or third position sensors 170-2 and 170-3, the control unit 130 may control the menu screen 200-1 to move to the right on the first display unit 160-1 and then towards the second and third display units 160-2 and 160-3, so that the menu screen 200-1 may be displayed according to the movement of the user.
Additionally, if the user is located in front of the center between the second position sensor 170-2 and the third position sensor 170-3, the control unit 130 may control the GUI generating unit 140 to display one half 200-2 of the menu screen 200-1 on the second display unit 160-2 and to display the other half 200-3 on the third display unit 160-3.
Accordingly, when the plurality of vending machines are connected in series, the menu screen may move horizontally as the user moves to the right or left, so it is possible for the user to buy a desired product more conveniently and induce the user to buy products.
FIG. 9 is a flowchart illustrating a process of displaying the menu screen 200 according to the horizontal movement of the user.
The position sensor 170 determines whether the user comes within a predetermined radius of the vending machine 100 (S410). If it is determined that the user is not located within the predetermined radius (S410-N), the control unit 130 causes the information providing screen or advertisement screen to be displayed on the display unit 160 (S450).
If it is determined that the user is located within the predetermined radius (S410-Y), the control unit 130 causes the menu screen 200 to be displayed on a part of the display unit 160 corresponding to the position of the user (S420).
If the user does not approach the vending machine 100, the vending machine 100 may determine that the user does not intend to buy products, and may then display the information providing screen or advertisement screen to induce the user to buy products. Alternatively, if the user has approached the vending machine 100, the vending machine 100 may determine that the user desires to buy products, and may then display the menu screen 200 so that the user can buy a desired product via the menu screen 200.
If it is determined that the user moves to the left or right (S430-Y), the control unit 130 controls the menu screen 200 to move in a direction in which the user moves (S440).
Therefore, the vending machine 100 displays the menu screen 200 according to the horizontal movement of the user, so it is possible for the user to more easily and simply buy desired products, and for a product provider to induce the user to buy products, thereby increasing sales.
