Abstract: As disclosed herein, an in-store feedback system permits shoppers to provide positive or negative feedback for a particular item using gestures or spoken language. To do so, the feedback system includes a gaze tracking module that identifies what product a shopper is currently focusing on. For example, a rack, which may contain multiple rows of shelves, is divided into a grid that includes a plurality of cells. By determining what cell the shopper is currently staring at, the gaze tracking system can identify a particular item by knowing which items are placed in which cell. The in-store feedback system may also include a gesture recognition system that identifies and decodes a gesture made by the shopper. For example, a thumbs up is positive feedback but a thumbs down is negative feedback. By recognizing the gesture, the gesture recognition system assigns positive or negative feedback to the item.

Abstract: Systems, methods, and computer program products to perform an operation comprising receiving selection of a food, determining a measure of similarity between the selected food and a plurality of taste preferences, wherein the measure of similarity is based at least in part on a plurality of taste attributes of the selected food, wherein each attribute of the plurality of taste attributes specifies a respective magnitude of a fundamental taste, of a plurality of fundamental tastes, and wherein each taste preference in the plurality of taste preferences specifies a respective preference for each fundamental taste, and upon determining that the measure of similarity is within a similarity threshold, displaying an indication that the selected food is preferable relative to the plurality of taste preferences.

Abstract: A local Point-of-Service (POS) server can receive requests from POS terminals on the local network that are unable to communicate with a central POS server due to, for example, a loss of network connectivity. The local POS server can generate transactions based on the requests, and store the transactions in a queue. The local POS can then transfer the queue to a recovery agent executing on the central POS server once connectivity has been restored. The central POS server can process a transaction by invoking an API of an order management system using a command and input parameters comprised within a transferred transaction.

Abstract: Systems and methods for provision of feedback information to point of sale device operators based on performance measures are disclosed. According to an aspect, a method includes determining an operator performance measure at a point of sale (POS) device. The method also includes generating, based on the operator performance measure, an interface for operator input. Further, the method includes receiving operator input to the interface. The method also includes providing feedback information based on the operator performance measure and the operator input.
