Location-enabling Your Grocery Store: Indoor Positioning Locates Your Favorite Peanut Butter And More

Directions Magazine (DM): Let's beginning with the basics. What methods are you contracting to encouragement indoor positioning for shoppers at grocery stores or malls? What turn of positioning accurateness are you able to supply once a finding is initiated?

Brian Wilson (BW): When we're knowledge to the locations of Wi-Fi access points in a venue we'll chart the and supply the locations to Skyhook, Google and Apple for inclusion in their databases. Once propagated by their systems, users' locations reported by the handset should simulate the larger accurateness supposing by the extra nodes. We design accurateness to normally be in the 5-30 scale range. And when you say generally, we're unequivocally seeking at 68% (i.e. 1-sigma) of the time.

DM: You've mapped considerably a couple of malls and store locations. Can you supply a few credentials data on how you combined these maps?

BW: Our inner group creates any map. We've combined a exclusive program apparatus that allows us, after getting indicate of fascination (POI) and other data about the space, to hurriedly create a geospatially exact chart of the tangible geography. Also note the mapping apparatus does not confine us to indoor venues; you could only as simply chart a thesis playing field or college campus, et cetera. The exclusive processes we've determined and apparatus you use are traffic secrets, with patents pending, so I'm not able to say more than that. Suffice to say that with a very tiny group you are formulating maps at a very hurried pace.

DM: Were mall developers peaceful to supply their engineering or CAD drawings in order for you to have very exact drawings of the buildings? Do you intend to create 3D models and BIMs from any drawings you obtain?

BW: We're using a few mall developers who are providing their maps (in a few cases CAD drawings, in others, only solid inhibit blueprint maps or franchise maps). However, our network does not indispensably need that you have precise, minute building outline maps as a starting indicate for formulating our maps. In a few cases you beginning with nothing. As for 3D models or 3D BIMs, we're adding OGC agreeable displaying to our apparatus set and design to tell our initial GML formatted venue shortly.

DM: Generally, grocery stores follow very identical layouts from store to store. Have you been able to simply replicate a store building chart via a since retailer's chain? What modifications, if any, do you have to make between stores?

BW: Although there are frequently many similarities in the simple building skeleton for a since retailer, so far we've found there are normally sufficient subtleties between locations to aver particular mapping efforts. Department layouts are frequently driven by a store-specific planogram system, and because it's critical that you create an exact illustration of the space, you make the extra bid to make any chart unique.

DM: Inside the store, planograms have become a scholarship unto themselves. How do you soak up planograms in to your app or are you simply mapping the 2D place of any particular SKU?

BW: Planogram systems do have an accounting of the shelf or brace place where a product may reside, but user contrast shows that mapping to that fealty doesn't increase sufficient worth to aver the extra POI overhead. An median considerable format tradesman contains 3 to 5 thousand POIs. Adding the shelf or brace fortitude increased that number to hundreds of thousands. We're now working on an cultured answer to explain the Z pivot in more item and will increase it to our gift if user contrast proves there's a benefit.

DM: Are you able to chart every SKU for any store?

BW: Since we're receiving the data right away from the retailer's system, we're contingent to a great border on the high quality of the data you take (though you moreover have a routine for "cleaning" and normalizing them). The partial answer is: we're able to chart every SKU that's done existing to us. Note that our network can moreover attend to not similar granularities of information. For example, if a correct shelf place is not provided, but the item is categorized appropriately, you can still place it in the correct subdepartment on the map. This typically happens in wardrobe and shoe departments where several racks have rollers and are frequently changed to assimilate seasonal register fluctuations.

DM: Will you be, or are you now, using the phone's camera to encouragement club chart approval to be able to collect pricing data or number of units in stock?

BW: This ability was not enclosed in the 1.0 Meijer Find-it launch, but it's a underline we've updated to the roadmap, and you design an associate to solicit it in the future. We'll be using our allies to prioritize features on the product roadmap.

DM:  How do you intend to confederate location-based promotion from mall or store merchants, and will they offer electronic couponing as segment of their Point Inside app?

BW: We now have a Web-based "portal" for our sell and mall allies that allows them to create, report and tell mobile promotions and eventuality data to the Point Inside focus for malls and airports. This same infrastructure is being leveraged to tell weekly sale specials in the Meijer Find-it app. So, we're already gift this capability, even though it's still early, and you haven't focused poignant sales efforts in that area to-date.

DM: Can you tell us more about your business model? Do merchants pay you to chart the store? Will you be entangled in fixation electronic ads, and is that a service you will offer?

BW: Our business model may be epitomised below. Note that depending on the definite incident there might be any multiple of up-front fees, per-use fees, income sharing, et cetera entangled in the relationship. I'm not able to go in to definite sum concerning any particular understanding at this time.
