My eyes were instinctively doing what they do when I need to search my computer: looking for the OS X Spotlight icon in the top-right corner.
I needed to find something in the real world and my brain was trying to Spotlight search for it. At that moment, I realized that online shopping was probably going to be a better idea from then on. I also realized that I spend too much time in front of computers.
For those who still enjoy the act of walking around with a cart and picking up their own products, U.K. retail juggernaut Tesco has come up with a new techno solution: turn-by-turn satellite navigation for supermarkets.
Despite the "satnav" nickname, it isn't satellite technology at all. It depends on good old-fashioned Wi-Fi.
Activate the app as you arrive, and it will show you a map of the store and a suggested route, the quickest possible for finding all the stuff on your shopping list.
The Android-only app is available to a small number of beta testers in a single store, and it's being released purely in the name of research. Tesco is genuinely curious to find out if, and how, people will use it.
