Abstract: A product assistant device may attach to a shopping cart or other baggage cart and provide information and guidance on products within a retail space. The assistant device may provide physiological information from sensors such as heart rate, blood pressure, or other non-invasively measured characteristics via a display. As the device moves through a retail space it may wirelessly communicate with beacons placed around the retail space in order to provide location specific information on products that may be nearby. Information may include pictures, health impact, selection guides, recipes, and directions to other locations within the retail space where other products and beacons may be located. Using such a system, a number of beacons and corresponding information displays may be used to guide a shopper through the store and introduce them to healthier food choices.
