Abstract: Embodiments herein describe providing feedback to a shopper at a POS system using a computer vision system. Many items at a store may lack barcodes or other identifying marks such as produce. The shopper may have to perform an action to identify the item to the POS system. The computer vision system can double check the identify provided by the shopper to reduce mistakes and deter nefarious actors. If the computer vision system cannot independently confirm that the item being purchased matched the identity provided by the shopper, the POS system can display a graphical user interface (GUI) that includes an image of the item captured by the computer vision system along with identification data of the item identified by the shopper. This gives the shopper a chance to correct any mistakes.

Abstract: An operating handle for an aerosol container features a hand grip portion, a shell portion and a trigger assembly interconnecting the hand grip portion and the shell portion. The trigger assembly includes an actuator arm for engaging the plunger head of an aerosol container and a trigger arm projecting along the hand grip portion whereby the trigger arm can be squeezed toward the hand grip portion to drive the actuator arm against the plunger head. The shell portion serves as a receptacle in which the aerosol can is secured and as a shield for isolating the hand and fingers from exposure to the aerosol spray. A quick release fastener assembly is carried by the shell portion for securing the aerosol container in a stable, upright operating position within the shell.
