Friday’s version of the Futurist begins a "hands-off" relationship with your computer. While computers have changed dramatically over the years, the way we use them is the same. We put our fingers on the keyboard. That is until now.  

With "Leap" you control your computer through touch free motion.  It works great for video games, plus you can let friends Google restaurants on your computer, and you don't have to Purell the keyboard afterward.  

One problem, without a traditional keyboard, cats will have to figure out new ways to fill your emails with typos.   

Next on the Futurist is this amazing gadget. Ever have that feeling you forgot to lock the door? Lockitron allows you to lock or unlock your doors from anywhere, through your smartphone.  If only it could turn off the gas and straighten the fringes on your carpet the same way. 

Lockitron even has a “knock” sensor so your phone will let you know when someone's at the door.

Finally, we have robots – from Japan. Here comes Kuratas, a 13-foot robot weighing 12,000 pounds.  Kuratas goes 7 miles per hour and can be controlled remotely or by a pilot sitting inside it.  It's available for just $1.3 million.

So if someone hacks into your Lockitron and goes in your house, hopefully you have Kuratas there to greet them and crush them like measly ants.

Now back to the present on The Futurist.
