Gaming could become very realistic due to new technology created by Dina Katabi’s research group at the MIT Computer Science and Artificial Intelligence Lab that enables highly precise, 3D motion detecting.

The new system, dubbed “WiTrack,” uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 centimeters — about the width of an adult hand. The researchers will present their findings during the Usenix Symposium on Networked Systems Design and Implementation in April 2014.

“Today, if you are playing a game with the Xbox Kinect or Nintendo Wii, you have to stand right in front of your gaming console, which limits the types of games you can play,” says Katabi, a professor of computer science and engineering and co-director of the MIT Center for Wireless Networks and Mobile Computing. “Imagine playing an interactive video game that transforms your entire home into a virtual world. The game console tracks you as you run down real hallways away from video game enemies, or as you hide from other players behind couches and walls. This is what WiTrack can bring to video gaming.”

Earlier this year, Katabi and her graduate student Fadel Adib unveiled WiVi, a system that detects humans through walls and can track the direction of their movement using WiFi signals. Based on this earlier work, Katabi and Adib developed WiTrack in collaboration with Rob Miller, a professor of computer science and engineering, and graduate student Zach Kabelac. In comparison to WiVi, WiTrack has significantly higher accuracy and can track both two-dimensional and three-dimensional movement using specialized radio waves, as opposed to WiFi signals.
