US Patent 10475185 Associating a user with an event

Described is a multiple-camera system and process for identifying a user that performed an event and associating that user with the event. For example, when an event is detected, user patterns near the location of the event are determined, along with touch points at the location of the event. User pattern orientation and/or arm trajectories between the event location and the user pattern may be determined and processed to link the user pattern to the event, thereby confirming the association between the event and the user.
