Abstract: A method is provided for monitoring status of subjects in an area for a system including a first data set identifying locations of subjects, a second data set identifying events in the area, and a third data set identifying whether accounts matched to the subjects exist. The method includes executing a graphical user interface including a map of at least part of the area including avatars identifying locations of subjects located on the map, and representing respective statuses assigned to the subjects located on the map, the statuses being assigned to the subjects based on one or more of the first, second and third data sets, wherein the assigning of the respective statuses to the subjects are assigned by utilizing at least one of the first, second and third data sets to determine that at least one subject of the subjects is a high risk of loss subject.

Abstract: Systems and techniques are provided for monitoring status of subjects in an area of real space. The system includes a display having access to memory storing a first data set identifying locations of subjects in the area of real space over time, a second data set identifying item put and take events in the area of real space and a third data set identifying accounts matched to the subjects in the first data set. The system includes a graphical user interface logic that renders a map on the display of at least part of the area of real space including avatars having locations on the map corresponding to locations in the area of real space according to the first data set, and identifying respective statuses assigned to the subjects based on one or more of the first data set, the second data set and the third data set.

Abstract: Systems and techniques are provided for automated shopping. The system processes sequences of sensor data to identify inventory events including item identifier and a classification confidence score. The system includes logic to generate and transmit digital receipts to devices linked to subjects in response to check-out events. The digital receipts include list of items based on the items in a log of items for the particular subject. The digital receipts can include links to graphical constructs for display on the device prompting input to request changes in the list of items. The system includes logic to process refund requests in response to messages from the device for the particular subject.

Abstract: Systems and techniques are provided for tracking multi joint subjects in real space having a plurality of cameras. The field of view of each camera overlaps with at least one other camera. The plurality of cameras produce respective sequences of images of corresponding fields of view in the real space. A processing system is coupled to the plurality of cameras. In one embodiment, the processing system comprises image recognition engines receiving sequence of images from the plurality of cameras and generating corresponding arrays of joint data structures. A tracking engine is configured to receive the arrays of joint data structures and generate candidate joints having coordinates in the real space. The processing system includes the logic to identify sets of candidate joints having coordinates in the real space as multi-joint subjects in the real space.
