Abstract: A method of delivering promotional content to a navigation application in a mobile device is provided. Knowledge of user interest inferred from a query and expected future location is used to render an advertisement in the navigation application. The advertisement is selected based on a location associated with a query received at the mobile device. In one design, advertisements are selected and rendered in a product-navigation application in a mobile device, which is used to determine the location of a product-choice. The advertisement for a promoted product is preferably rendered such that it represents the actual physical location of the promoted product in the store.

Abstract: A method of locating a product in a store using a mobile device is provided. The mobile device communicates with a store server through a local area network and retrieves location information for the product. Low granularity product and location information is received at the device from a store server as the user enters the store. Higher granularity location information is later received at the device depending on position of the device in the store. Pre-stored product choices in a shopping list application may be used to navigate to locations of successive products in the list.
