Abstract
A display system (299) includes a visual display unit (300) mounted on a shopping cart (12d). In one preferred embodiment, a low-intensity ultrasonic signal is emitted by a transmitter (308) positioned at a desired location within a store for reception by a transducer (306) mounted on the shopping cart. The signal from the transducer (306) is transmitted to a switching circuit (316) to activate visual indicators in the form of directional lights (320, 322) thereby to direct the shoppers attention to a particular item located adjacent the transmitter (308).
