Abstract: Dynamic signage systems are provided for a sales environment. A dynamic signage device (e.g., a tablet computer) is associated with a product, e.g., based on a location of the device and/or the product, and can present information about the product to a customer in an interactive manner. The device can automatically check for updated product information and modify its display based on the updated product information. Management of multiple dynamic signage devices can be coordinated within and across stores, and an interactive floor-map creation system incorporating dynamic signage devices can facilitate changing the associations between products and dynamic signage devices.
