Productopia | CES

Eye-tracking software, Gaze, from Tobii Technology, allows computer users to navigate to a website with a glance, blow up asteroids in a game with a head nod, or scroll through photo slideshows without ever clicking a mouse.

Up until now, eye-tracking technology was cumbersome, but according to Mashable, this is all about to change with the new Tobii innovations. Debuting at CES in Las Vegas last week, the screen now tracks both head and eye movements, combining both to direct the computer to do what the user wishes. Attendees were able to test it out. A game similar to Asteroids was available and users could explode asteroids simply by staring at them and navigate the joystick with their gaze.

If you haven't yet dropped your phone in the toilet, there's a pretty good chance you will. According to 2011 Google survey, 39% of us take our phones into the bathroom with us; and a separate survey commissioned by Plaxo found that 19% of us have dropped them in the toilet. Enter the Fujitsu waterproof Android smartphone and tablet computer unveiled this week at CES. Product reps demonstrated these water-resistant gadgets by dunking them into a bowl of water for 30 minutes.

At Consumer Electronics Show, it's hard to miss Sony, LG, Panasonic, etc. But sometimes -- actually, make that most time -- the thing that makes you stop and say "whoa, that's just cool" can be found in the smallest booths tucked away in the farthest reaches of the show's most remote exhibition hall. At this year's CES, one product that delivered that cool factor for me was the MakerBot Replicator 3D printer.

While Nintendo did not have a presence on the show floor at the Consumer Electronics Show in Las Vegas, a team of company representatives held court in the adjoining The LVH Hotel showing off the much anticipated Nintendo Wii U to invited guests, including yours truly. Though I'm certainly no hardcore gamer -- not with my fist full of thumbs -- the chance to see what all of the hubbub is about was far too good to pass up. So, did the Wii U live up to the hype? Yeah, pretty much, though there are still plenty of question marks.
