You can use your finger to flick in the air to mute the smartphone that is playing the song in your pocket, or you can use your hand to pause the voiced magazine. A research team at the University of Washington established a batteryless, low-cost gesture recognition system that allows users to control electronic devices hidden outside the line of sight with simple hand motions. Its prototype is called "AllSee". This technique of gesture-controlling electronic devices may soon become a touch screen sensing technology that replaces smart phones and tablets that consume large amounts of power. The technology will be announced at the symposium of the Seattle Network System Design and Implementation Conference on April 2-4. "This is the first gesture recognition system that implements less than a dollar and does not require battery power to use television signals as both a source of power and a source of gesture recognition," said Shiyam, assistant professor of computer science and engineering at the University of Washington. ." Researchers built a small sensor that can be placed on electronic devices such as smart phones. The sensor uses an ultra-low power receiver to extract and classify gesture information from the wireless transmissions around us. When a person gestures by hand, the amplitude of the wireless signal in the air changes, and the AllSee sensor can recognize this unique amplitude change caused by a particular gesture. According to the report of the physicist's organization on February 27th, the research team used eight different gestures on smartphones and batteryless sensors to test AllSee's functions such as pushing, pulling, coming, zooming in, and zooming out. The prototype correctly recognizes more than 90% of gestures, and can perform device manipulation beyond 2 feet. The researchers also designed a wake-up gesture so that the system does not confuse inadvertent actions with actual gestures. For users, this is a seamless interactive experience. This gesture recognition can be installed on some mobile devices, including the Samsung Galaxy S4 smartphone. However, the user must first manually enable this feature and then be able to see that the device's gesture technology is working. The technology can also be attached to home electronics, interact with gestures, connect them to the Internet, and play a role in the “Internet of Things†world. "AllSee goes beyond mobile devices and allows IoT devices to interact with each other," said Bryce Kellogg, a doctoral student in the Department of Electrical Engineering at the University of Wisconsin.
