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 toward
products on your list. The system will also warn you if you’ve added something
that violates your dietary restrictions. Items you add to the cart can be
automatically scanned, and you can finalize your purchase from the device.
A team of Dutch and Italian researchers has found that the
way you move your phone to your ear while answering a call is as distinct as a
fingerprint. You take it up at a speed and angle that’s almost impossible for
others to replicate. Which makes it more reliable password than anything you’d
come up with yourself. Down the line, simple movements like the way you shift
in your chair, might also replace passwords on your computer. It could also be
the master key to the seven million passwords you set up all over the Internet
but keep forgetting.
