A method and system for providing an enhanced and interactive window shopping and retail information exchange with shoppers, includes acoustic sensing in connection with one or more storefront windows of a retail store, and a corresponding transparent display located within the store and visible through the storefront window, the interior of the store being visible through the transparent display. Display of information on the transparent display, and in optional combination with audio information external to the store, prompts shoppers to tap the storefront window at locations which correspond to the locations of information displayed on the transparent display. The system and method is programmed to respond to taps on the window according to the locations of the taps with incentives to enter the store and/or to redeem awards or coupons in the store.
