Remote control over wifi

Want to control a TV or music player with just one wave and from any room in the house? A new wireless-based motion detection system can make this possible.

Researchers at the University of Washington have unveiled a WiSee device that works to take advantage of the active wifi connection for users to turn off the player or switch TV channels. present a specific gesture. Unlike other motion detection systems, such as Kinect or Leap Motion, WiSee does not need the presence of cameras, so you do not have to be in front of a television or computer to perform these actions. . Even, the user is completely free to control electronics or household electrical appliances from anywhere in the house.

WiSee leverages wireless signals from devices you already have in your home, such as smartphones, tablets and laptops, according to a Washington University expert. These wireless signals bounce off of the human body and are sent to the wireless router where they will be analyzed and used to control everything from heating equipment to the lighting system. . And thanks to MIMO technology (roughly translated as import multi - multi output), WiSee can even distinguish the individual movements from different.

Accordingly, each user has specific gestures that they usually do unconsciously before issuing commands through gestures. Researchers say the prototype of the new system was able to identify and classify a group of nine movements with an average accuracy of about 94 percent. And experts say that installing this groundbreaking new system is as simple as attaching a wifi router, which adds WiSee software applications.

In fact, the new applications in the field of motion control are gaining the special attention of consumers as well as developers. Recently, the popular online music download service Grooveshark has added the Flutter app, allowing the listener to gesture to play or pause a movie soundtrack, or control a music player on a laptop or desktop. And the new, compact Kinect sensor family may soon be incorporating gesture recognition technology into mobile phones or tablets.
