Can Wi-Fi let you see people through walls?

Do you really wish you had X-ray vision? Sure, it would be fun to see what your neighbors are doing behind those walls -- until you see something you wish you hadn't.

Regardless, researchers at MIT have developed a sensing technology that uses low-power Wi-Fi to detect moving people. It follows other wall-penetrating sensor tech using radar and heavy equipment.

The Wi-Vi system by Dina Katabi and Fadel Adib sends out a low-power Wi-Fi signal and tracks its reflections to sense people moving around, even if they're in closed rooms or behind walls. … Read more

Smile! We know how fast your heart is beating

Have you ever noticed your head rocking back and forth very slightly when you sit still? That's the effect of blood rushing up to feed your brain.

Now Massachusetts Institute of Technology researchers can accurately measure that phenomenon on regular video and figure out how fast someone's heart is beating. They say it might help detect cardiac disease.

The scientists at MIT's Computer Science and Artificial Intelligence Laboratory believe the algorithm could be used for video monitoring of patients with sensitive skin, such as newborns or elderly people. … Read more

MIT to turn sky into dancing-umbrella light show

Forget the Umbrellas of Cherbourg. MIT presents the Umbrellas of Cambridge.

This Sunday evening, participants in a large-scale interactive performance will hoist programmable umbrellas outfitted with LED lights skyward in a shimmering spectacle of red, green, and blue.

The project, called "UP: The Umbrella Project," is part of a collaboration between MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and the Connecticut-based Pilobolus modern-dance company.

Using hand controllers designed by researchers at CSAIL's Distributed Robotics Lab, hundreds of MIT students, faculty, and staff will be able to independently change the color of their umbrellas, thus spontaneously choreographing a kind of umbrella dance that will then be projected onto a giant screen so everyone can see the aggregate moving image. … Read more

Sweet! Bakebot robot makes cookies

If there's one thing we know for sure, it's that humanity is only a few years away from the robot armageddon. The robots are improving too quickly and building each other too rapidly to stop. At least we can console ourselves by laughing at the robots of today. Like this bakebot. "A robot baking? How hilarious," you say. Well, get your chuckles in while you can, human. (It's actually pretty funny though.)

Personal favorite part of the video below? When Bakebot tosses the empty bowl on the floor. Just like a real chef! (We all do that, right?) Bakebot is well-known at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), where it was built by MIT graduate student Mario Bollini.

Bollini cooked up the bakebot using the PR2 research and development platform, developed by Willow Garage, to bake chocolate chip cookies from scratch.

"My task is to have the PR2 bake cookies all the way from locating the ingredients in front of it on the table to putting the cookie in the oven," Bollini said.

The bakebot (which is not the first robot chef we've seen) begins by examining the table using a laser scanner and camera to locate the cookie sheet and butter. It identifies all the other ingredients and supplies by color and size. The robot then follows a coded version of the recipe that takes it through mixing the ingredients, scraping the cookie dough onto the baking sheet, and patting it into a large cookie. … Read more
