 Welcome to Linus Tech Tips at CES 2013. Our trip to the show this year is powered by Corsair, maker of quality PC components and peripherals. Our trusted storage partner is Seagate Technology, and our trusted networking partner is Linksys. The first thing here is perceptual technology. So this is basically the concept of interacting with computers in ways that do not involve directly touching them, interacting with a keyboard or mouse, or something like a touch screen. So a few examples of how you can use this and how it might be implemented are actually here on display right now. So right here we have what is more than just a webcam. This is an IR emitter, an IR receiver, as well as a regular webcam. So it can do some very cool things. Number one is because of the way that you interact with it, you can do not only just 2D gestures, but also 3D gestures, much like something like Microsoft Connect. Because of the infrared camera, it can do a bunch of other stuff as well, including pick up on your emotions in ways that can tell you things like, okay, so it knows your heart rate, it knows your pupil dilation, it knows kind of how you're feeling about something. So maybe you're playing a video game with someone and you're using this kind of a perceptual computing concept to play. It might say something like, look, your gaming partner is getting bored. It might be time to switch games. Or if you watch a movie, it might go, hey, you watched a movie like that before and you didn't really like it. You weren't enjoying yourself when you were watching it. Are you sure you want to check that out? So one of the ones over there actually has a guy operating what is sort of like a, you know, gravity gun or something along those lines. And you can see, you can manipulate it in 3D space just like this, move it forward, move it back. Another example right here on the tourney table down here is using this idea to put me inside of a virtual space. Now, obviously, this is a very early version and there's going to be a lot of work to be done before this is ready for prime time. But it's a very interesting concept. Thanks for watching Linus Tech Tips at CES 2013, powered by Corsair, Seagate Technology, and Linksys.
