  • Publication number: 20220009537
    Abstract: According to one embodiment a shopping cart includes an imaging unit configured to acquire images of a surface at a location of the shopping cart and a controller. The controller is configured to detect a boundary pattern in images acquired by the imaging unit. The boundary pattern is painted or drawn on the surface at a boundary between a first area and a second area. Based on the detected boundary pattern the controller determines whether the shopping cart has been moved from the first area to the second area or from the second area to the first area. The controller then controls mobility of the shopping cart based on whether the shopping cart has been moved from the first area to the second area or from the second area to the first area.
