Abstract

The embodiments of the present disclosure provide a method for selling a commodity, a vending machine and a storage medium. The method includes: acquiring an image of eyes of a user, determining based on the image of eyes a gaze point of the user within a commodity displaying plane matching a vending machine; determining, based on position coordinates of at least two commodities in the commodity displaying plane and the gaze point, an expected commodity corresponding to the user; providing commodity indication information of the expected commodity to the user; and in response to detecting purchase confirmation information fed back by the user for the commodity indication information, guiding the user to use at least one biological characteristic to finish payment for the expected commodity.

First claim

What is claimed is:

1. A method for selling a commodity, applied to a vending machine comprising an image processing device, an input/output interface and a processor, the method comprising:
acquiring, by the image processing device, an image of eyes of a user, determining by the processor based on the image of eyes a gaze point of the user within a commodity displaying plane matching the vending machine;
determining, by the processor based on position coordinates of at least two commodities in the commodity displaying plane and the gaze point, an expected commodity corresponding to the user;
providing, by the input/output interface, commodity indication information of the expected commodity to the user; and
in response to detecting purchase confirmation information fed back by the user for the commodity indication information, guiding, by the processor, the user to use at least one biological characteristic acquired by the input/output interface to finish payment for the expected commodity;
wherein, guiding the user to use at least one biological characteristic to finish payment for the expected commodity comprises:
providing, by the input/output interface, payment information corresponding to the expected commodity to the user and indicating the user to input at least two biological characteristics respectively through the input/output interface;
acquiring, by the processor, target payment accounts corresponding respectively to the at least two biological characteristics, and performing, by the processor, based on the payment information a payment operation matching in response to determining that target payment accounts corresponding respectively to the at least two biological characteristics are identical;
wherein the biological characteristic comprises face, voice print, iris and fingerprint;
wherein detecting the purchase confirmation information fed back by the user for the commodity indication information comprises:
in response to identifying a standard head action based on at least two frames of images of the user captured by a camera, determining that the purchase confirmation information is detected;
wherein the standard head action comprises nodding or blinking;
wherein providing the commodity indication information of the expected commodity to the user comprises:
determining position recognition information of a state indicator light matching the expected commodity; and
flickering the state indicator light matching the position recognition information to generate the commodity indication information for providing to the user.

2. The method of claim 1 , wherein, providing the commodity indication information of the expected commodity to the user comprises:
acquiring commodity description information of the expected commodity, constructing based on the commodity description information the commodity indication information; and
providing the commodity indication information to the user via speech broadcasting.

3. The method of claim 1 , wherein, detecting the purchase confirmation information fed back by the user for the commodity indication information comprises:
in response to identifying a confirmation key term based on user speech information acquired by a microphone, determining that the purchase confirmation information is detected.

4. A vending machine, comprising:
an image processing device;
an input/output interface;
one or more processors;
a memory for storing one or more programs;
wherein when the one or more programs are executed by the one or more processors, the vending machine is one or more processors are caused to perform the method for selling a commodity, comprising:
acquiring, by the image processing device, an image of eyes of a user, determining by the one or more processors based on the image of eyes a gaze point of the user within a commodity displaying plane matching the vending machine;
determining, by the one or more processors based on position coordinates of at least two commodities in the commodity displaying plane and the gaze point, an expected commodity corresponding to the user;
providing, by the input/output interface, commodity indication information of the expected commodity to the user; and
in response to detecting purchase confirmation information fed back by the user for the commodity indication information, guiding, by the processor, the user to use at least one biological characteristic acquired by the input/output interface to finish payment for the expected commodity;
wherein, guiding the user to use at least one biological characteristic to finish payment for the expected commodity comprises:
providing payment information corresponding to the expected commodity to the user and indicating the user to input at least two biological characteristics respectively;
acquiring target payment accounts corresponding respectively to the at least two biological characteristics, and performing based on the payment information a payment operation matching in response to determining that target payment accounts corresponding respectively to the at least two biological characteristics are identical;
wherein the biological characteristic comprises face, voice print, iris and fingerprint;
wherein detecting the purchase confirmation information fed back by the user for the commodity indication information comprises:
in response to identifying a standard head action based on at least two frames of images of the user captured by a camera, determining that the purchase confirmation information is detected;
wherein the standard head action comprises nodding or blinking;
wherein providing the commodity indication information of the expected commodity to the user comprises:
determining position recognition information of a state indicator light matching the expected commodity; and
flickering the state indicator light matching the position recognition information to generate the commodity indication information for providing to the user.

5. The vending machine of claim 4 , wherein, providing the commodity indication information of the expected commodity to the user comprises:
acquiring commodity description information of the expected commodity, constructing based on the commodity description information the commodity indication information; and
providing the commodity indication information to the user via speech broadcasting.

6. The vending machine of claim 4 , wherein, detecting the purchase confirmation information fed back by the user for the commodity indication information comprises:
in response to identifying a confirmation key term based on user speech information acquired by a microphone, determining that the purchase confirmation information is detected.

7. A computer-readable storage medium having a computer program stored thereon, wherein, when the computer program is executed by a processor of a vending machine comprising an image processing device and an input/output interface, the processor performs the method for selling a commodity, comprising:
acquiring, by the image processing device, an image of eyes of a user, determining by the processor based on the image of eyes a gaze point of the user within a commodity displaying plane matching the vending machine;
determining, by the processor based on position coordinates of at least two commodities in the commodity displaying plane and the gaze point, an expected commodity corresponding to the user;
providing, by the input/output interface, commodity indication information of the expected commodity to the user; and
in response to detecting purchase confirmation information fed back by the user for the commodity indication information, guiding, by the processor, the user to use at least one biological characteristic acquired by the i
