Abstract

The application describes a system and process for anticipating when a user will leave a selection area within a materials handling facility and determining if a notification requesting that the user provide a tote of picked items to a drop off location should be presented to the user. For example, a user may be asked to provide items picked from a selection area for processing, such as packing, while the user is picking items from other selection areas of a materials handling facility.

Claims

1. A computer-implemented method for notifying a user to provide an item to a drop off location, comprising:

determining that a user is located within a selection area of a materials handling facility, wherein the selection area includes a plurality of items of a similar type that are available for picking by the user;

determining that the user has picked at least one of the plurality of items;

associating the picked at least one item with the user;

determining that the user is departing the selection area of the materials handling facility;

determining that the user has not provided the picked at least one item to the drop off location for processing; and

sending a notification for presentation to the user requesting that the user provide the picked at least one item to the drop off location for processing.

2. The computer-implemented method of claim 1, wherein determining that the user is departing the selection area is based at least in part on one or more of:

processing an image of the user to determine at least one of a location or a direction of movement of the user, monitoring a position of the user, or determining that the user has picked all items identified on a pick list that are available in the selection area.

3. The computer-implemented method of claim 1, wherein:

the drop off location is a physical location in the selection area configured to receive picked items and cause the received picked items to be transitioned to a processing area for additional processing; and

the processing includes at least one of packing the at least one item, assembling the at least one item, gift wrapping the at least one item, preparing the at least one item, weighing the at least one item, or identifying the at least one item.

4. The computer-implemented method of claim 1, wherein:

associating the at least one item with the user includes associating the at least one item with a tote that is associated with the user;

wherein the association between the user and the at least one item or the association between the user and the tote are maintained after the user provides the tote to the drop off location; and

the notification includes a request that the user provide the tote to the drop off location.

5. The computer-implemented method of claim 1, wherein the notification is sent to at least one of an output device within the materials handling facility or a portable device in a possession of the user.

6. The computer-implemented method of claim 1, further comprising:

determining that the user has provided the at least one item to the drop off location; and

subsequent to determining that the user has provided the at least one item, maintaining the association between the user and the at least one item.

7. The computer-implemented method of claim 1, wherein the notification is sent to at least one of an output device located within a materials handling facility, an agent located within the materials handling facility, or a portable device in a possession of the user.

8. The computer-implemented method of claim 1, further comprising:

determining that the user has provided the at least one item to the drop off location;

subsequent to determining that the user has provided the at least one item to the drop off location, determining that a processing of the at least one item has completed; and

subsequent to determining that the processing of the at least one item has completed, storing the at least one item in a buffer area until the at least one item is provided to the user.

10. The computing system of claim 6, wherein:

the tote is associated with the user; and

the item placed in the tote is associated with the tote.

9. A computing system, comprising:

one or more processors; and

a memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least;

determine that a user is located within a selection area of a materials handling facility, wherein the selection area includes a plurality of items that are available for picking by the user;

determine that the user has picked at least one of the plurality of items and placed the item in a tote;

determine that a notification that includes a request that the user provide the tote to a drop off location be presented to the user;

send the notification for presentation to the user;

determine that the user has provided the tote to the drop off location; and

maintain an association between at least one of the user and the tote or between the user and the item after the user has provided the tote to the drop off location.

11. The computing system of claim 9, wherein the notification is sent to at least one of an output device located within a materials handling facility, an agent located within the materials handling facility, or a portable device in a possession of the user.

12. The computing system of claim 9, wherein the drop off location is at least one of a stationary location within the materials handling facility configured to receive the tote;

a mobile drive unit configured to move within the materials handling facility and receive the tote;

or an agent located within the materials handling facility configured to receive the tote.

13. The computing system of claim 9, wherein the notification further includes guidance to assist the user in locating the drop off location.

14. The computing system of claim 9, wherein the determination that the notification that includes a request that the user provide the tote to a drop off location be presented to the user is based at least in part on a determination that the user is leaving the selection area, a determination that a weight of the tote exceeds a threshold, or a determination that at least one picked item be separated from an item that is anticipated to be picked by the user while the user is in the selection area.

15. A computer-implemented method, comprising:

under control of one or more computing systems configured with executable instructions,

determining that a user is located within a selection area of a materials handling facility, wherein the selection area includes a plurality of items that are available for picking by the user;

determining that the user has picked at least one of the plurality of items and placed the item in a tote;

determining that the user has placed the tote at a drop off location; and

maintaining an association between at least one of the user and the tote or between the user and the item as the item is processed at a processing area of the materials handling facility.

16. The computer-implemented method of claim 15, further comprising:

determining that the item has been removed from the tote and placed into a second tote;

creating an association between the second tote and the user; and

terminating the association between the user and the tote.

17. The computer-implemented method of claim 16, wherein the second tote includes additional items picked by the user.

18. The computer-implemented method of claim 15, further comprising:

determining that a processing of the item has completed; and

temporarily storing the item in a buffer area until the item is provided to the user as the user transitions from the materials handling facility.

19. The computer-implemented method of claim 18, wherein the processing includes at least one of packing the item, assembling the item, gift wrapping the item, preparing the item, weighing the item, or identifying the item.

20. The computer-implemented method of claim 15, wherein the user places the tote at the drop off location in response to receiving a notification that includes a request that the user place the tote at the drop off location.

21. The computer-implemented method of claim 15, wherein the drop off location is at least one of a stationary location within the materials handling facility configured to receive the tote;

a mobile drive unit configured to move within the materials handling facility and receive the tote;

or an agent located within the materials handling facility configured to receive the tote.

22. The computer-implemented method of claim 15, further comprising:

providing a notification to the user indicating at least one of;

that a processing of the item has completed, or a time by which the processing of the item will be completed.
