WiSee system recognizes user gestures in other rooms. By now, even if they’ve never used one themselves, most people are pretty familiar with the idea behind gesture control systems such as the Kinect – the user makes a movement, the device “sees” that movement, and interprets it. However, what would happen if the user was in another room, blocked from the device’s cameras and depth sensors? Well, as long as there was a Wi-Fi signal available, it wouldn’t be a problem ... at least, not if the WiSee system was being used. Created by a University of Washington team led by Prof. Shyam Gollakota, the technology utilizes nothing but the Wi-Fi signals already present in a room, such as those emitted by smartphones or laptops. Those signals travel through the interior walls of the building, and are monitored by a centrally-located WiSee receiver – although a regular Wi-Fi router could also be adapted for the same purpose.
