Low Energy Radio Frequency Query and Location Method for Optical Head Mounted Displays

A system is needed to assist users in locating items of interest in a brick-and-mortar retail store, while also allowing the retailer to guide the user to specific items.

The novel contribution is a system that allows customers to enter a store with an electronic shopping list, and then push this list to the Bluetooth* Low Energy (BLE) network. The BLE network then communicates with the customer's optical head-mounted displays (OHMD) to visually present the location of the desired items. The customer can then request more information, (e.g., "Show discounted or sale items".)

Although this disclosure highlights use of Bluetooth* Low Energy (BLE), any low energy radio frequency (RF) protocol can accomplish the benefits described herein. This disclosure likewise calls out optical head-mounted displays (OHMDs) as the customer's computational device, but consideration should be given to the broad spectrum of wearable computers.

This system provides a more enticing user experience than just a sales coupon, instead providing a new level of engagement for customers, bridging the physical user experience with virtual presentation of relevant information.

A view from the OHMD for a customer's specific shopping list shows the store layout with callouts indicating the location of specific items on the list (e.g., men's socks, ladies' shoes, etc.), as located by the BLE in accordance with the customer's position in the store. The item drops from the display as the customer places items in a shopping cart. This allows the customer the opportunity for one last scan of the store to ensure that all items are found.
