Abstract: A system may generate image data of users within a facility. Such users may be part of a group that is unknown to the system. The system can predict group data for two or more users based on a resemblance or the users being within a threshold distance of each other. However, if a confidence level associated with the predicted group data is below a threshold value, the group data is deemed unreliable and assistance from an associate is deemed necessary. A user interface that includes a portion of the image data, information about the predicted group data, and other interface elements is presented to the associate via a display. Based on the input data received from the associate, the group data can be confirmed or rejected. If the group data is confirmed, an association is made between the users and a group identifier.

Abstract: This disclosure describes techniques for utilizing sensor data to determine the results of events within a system. Upon receiving sensor data indicative of an event, the sensor data is analyzed to determine a result of the event. For instance, a user may identified upon entry to a facility, may pick items from shelves in the facility, and may be identified upon exit. Contents of a virtual shopping cart of the user may be maintained based on analysis of the sensor data as the user picks the items. When a user exits, a payment instrument of the user may be charged for a cost of the items and a receipt may be sent to a device of the user. A state-invariant time, representing a time before which all events have been processed, may be maintained such that no shopping sessions are finalized prior to the state-invariant time to avoid mistaken charges.

Abstract: This disclosure describes techniques for determining whether a transaction may be finalized with a user that exits a facility. To do so, the inventory management system may first determine whether the inventory management is to resolve any events prior to finalizing the transaction. In some instances, the inventory management system may refrain from finalizing a transaction with a user that exits the facility if the user is associated with a low-confidence result/event, if the user remains a candidate user for an unresolved event, or if a global-blocking event is in place at the time of the user's exit. In some instances, meanwhile, the transaction with a user may be finalized upon the user's exit of the facility if the user is associated with high-confidence events/results, is not associated with any low-confidence events/results, is not a candidate user for an unresolved event, and if no global-blocking event is in place at the time of exit.

Abstract: In one or more implementations, groups of users enter a facility within a short time. Automated systems attempt to predict a grouping for various users, but the predicted grouping may not exhibit a confidence level above a certain threshold level. In such cases, a user interface is generated and presented to an associate to confirm the grouping of users. The user interface includes an image gallery and interface elements that allow for the selection of users into a group. The image gallery includes previously stored images of users, such as images obtained during a registration process or during a previous visit to the facility. In addition, the user interface also includes image data obtained from a camera at the facility depicting visitors at various times or locations. Once a grouping has been selected or confirmed by an associate, group data may be generated and stored for the group of users.

Abstract: Users may enter a facility singly or in groups. A user interface may be presented to an associate that includes information obtained from sensors in the facility. The associate may utilize the information presented to determine if a user is alone, or to associate that user with a particular group of users. Input from the associate obtained from this user interface may then be used by a facility management system during operation to attribute the actions of the users to a particular account.

Abstract: Users may enter a facility singly or in groups. Users may present entry credentials to a scanner. The entry credentials assist in identification of the user. After entry, users are tracked within the facility. If determinations about one or more of identification or tracking by an automated system fall below a threshold value, an employee associated with the facility is presented with a user interface. The user interface may include a gallery of images including those of the user and others in the facility. User input to the user interface is then used to reestablish one or more of identification or tracking.
