Ever spent ages wandering the grocery store while looking for a hard-to-find ingredient?
If Philips brings its new connected retail lighting to your local supermarket, you may always know where to go. The technology uses light-based communication to create a positioning grid for your smartphone, telling you just what route you’ll need to take to get everything for that recipe.
Naturally, shopkeepers can also use the system for location-based discounts and suggestions; if you’re looking for dessert ideas, the lights can point you to the pastry section. Philips is already testing its smart illumination with a handful of stores, so it might not be long before you’re shopping with extreme efficiency.
