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: Disclosed are various embodiments for facilitating social interaction during a media item transmission. A group of participants may be formed based on a variety of factors. A media item is rendered on a first portion of a media player user interface. On a second portion of the media player user interface group members may communicate with each other concurrent with the streaming media item. The entire experience may be stored and replayed at another time.
