Abstract

Methods, systems, and machine readable medium are provided for autonomous item identification in an environment including a mobile computational device and a container. One or more sensors are disposed at the container to sense a selected item being placed in the container. In response to sensing the selected item being placed in the container, a location of the container is determined using a positioning system. One or more physical characteristics of the selected item is sensed via the one or more sensors at the container. A set of stored characteristics is retrieved from a database for available items proximate to the location of the container. An identification code for the selected item is identified based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container.

Claims

1. A method for autonomous item identification in an environment including a mobile computational device and a container, the method comprising:

sensing, via one or more sensors disposed at the container, a selected item being placed in the container;

in response to sensing the selected item being placed in the container, determining a location of the container using a positioning system;

sensing one or more physical characteristics of the selected item via the one or more sensors at the container;

retrieving, from a database, a set of stored characteristics of available items proximate to the location of the container;

identifying an identification code for the selected item based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container; and

generating an alert at the mobile computational device if the selected item is not included in an item log representing a sales transaction.

2. The method of claim 1, wherein the alert is a message generated on a user interface of the mobile computational device.

3. The method of claim 1, wherein the alert is an audible sound generated at the mobile computational device.

4. The method of claim 1, wherein the one or more sensors includes a weight sensor coupled to a bottom portion of the container for sensing weight of the selected item placed in the container.

5. The method of claim 1, wherein the one or more sensors includes a light sensor coupled to the container for sensing placement of the selected item in the container in response to an interruption of light between an emitter and a receiver of the light sensor.

6. The method of claim 1, wherein the one or more sensors includes a temperature sensor coupled to the container for sensing temperature of the selected item placed in the container.

7. The method of claim 1, wherein the one or more physical characteristics of the selected item includes at least a weight of the selected item, a temperature of the selected item, a size of the selected item, or a color of the selected item.

8. The method of claim 1, wherein the mobile computational device is in communication with a server, and the server completes a transaction with the mobile computational device in response to identifying the selected item.

9. The method of claim 1, wherein the set of stored characteristics is stored for each of the available items with location information for each of the available items.

10. The method of claim 1, further comprising:

generating a task at the mobile computational device, the task indicating the user of the mobile computational device requiring assistance; and

transmitting the task to one or more hand-held devices associated with other users proximate to the location of the container.

11. The method of claim 1 further comprising retrieving data indicating available items proximate to the location of the container from a database when the sensors detect the selected item is placed in the container.

12. A system for autonomous item identification in an environment including a mobile computational device and a container, the system comprising:

one or more sensors disposed at the container configured to;

sense a selected item being placed in the container; and

sense one or more physical characteristics of the selected item;

a positioning system configured to determine a location of the container in response to the one or more sensors sensing the selected item being placed in the container; and

a server in communication with the mobile computational device and the one or more sensors, the server configured to;

retrieve, from a database, a set of characteristics of available items proximate to the location of the container;

identify an identification code for the selected item based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container; and

generate an alert at the mobile computational device if the selected item is not included in an item log representing a sales transaction.

13. The system of claim 12, wherein the one or more sensors includes a weight sensor coupled to a bottom portion of the container for sensing weight of the item placed in the container.

14. The system of claim 12, wherein the one or more sensors includes a light sensor coupled to the container for sensing placement of the selected item in the container in response to an interruption of light between an emitter and a receiver of the light sensor.

15. The system of claim 12, wherein the one or more sensors includes a temperature sensor coupled to the container for sensing temperature of the selected item placed in the container.

16. The system of claim 12, wherein the one or more physical characteristics of the selected item includes at least a weight of the selected item, a temperature of the selected item, a size of the selected item, or a color of the selected item.

17. The system of claim 12 wherein data indicating available items proximate to the location of the container is retrieved from a database when the sensors detect the selected item is placed in the container.

18. A non-transitory computer readable medium storing instructions to cause a processor to implement a method for autonomous item identification in an environment including a mobile computational device and a container, the method comprising:

sensing, via one or more sensors disposed at the container, a selected item being placed in the container;

in response to sensing the selected item being placed in the container, determining a location of the container using a positioning system;

sensing one or more physical characteristics of the selected item via the one or more sensors at the container;

retrieving, from a database, a set of stored characteristics of available items proximate to the location of the container;

identifying an identification code for the selected item based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container;

generating an alert at the mobile computational device if the selected item is not included in an item log representing a sales transaction.

19. The non-transitory computer readable medium of claim 18, wherein the one or more characteristics of the selected item includes at least a weight of the item, a temperature of the item, a size of the item, or a color of the item.

20. The non-transitory computer readable medium of claim 18, wherein data indicating available items proximate to the location of the container is retrieved from a database when the sensors detect the selected item is placed in the container.
