21 The mind-reading shopping cart

 In February, Chaotic Moon Labs began testing a robotic shopping cart that acts a bit like a mind-reading butler. To start it up, you can text message the cart’s built-in tablet computer. Now it knows who you are and what you need for dinner. The cart uses Microsoft’s Kinect motion-sensor technology to track and follow you through the store, pointing you — in a synthy voice reminiscent of a G.P.S. navigator — toward products on your list. The system will also warn you if you’ve added something that violates your dietary restrictions. Still only a prototype, the cart isn’t nearly as nimble as its human-powered cousin, but it does have one main advantage. Items you add to the cart can be automatically scanned, and you can finalize your purchase from the device, skipping the checkout line entirely. Farhad Manjoo
