离开公寓前忘了关灯?没问题。只要举起你的手,手指划过空气,灯光就会熄灭。正在播放音乐,想换一首?把你的手移向右边,歌曲就会翻篇。这就是美国科学家开发的手势识别新技术,可用我们周围的Wi-Fi信号来检测特定动作。研究人员证实,通过使用客厅里一个经改装的Wi-Fi路由器和几个无线设备,用户即可凭借手势在家里的任何房间操控自己的电子产品和家用电器。利用无线信号进行手势识别,免去了部署更多传感器的需要。
Forgot to turn off the light before leaving the apartment? No problem. Just raise your hand, fingers across the air, the light will go out. Playing music, want to change? Turn your hand to the right, the song will flip. This is the new gesture recognition technology developed by American scientists that uses the surrounding Wi-Fi signals to detect specific actions. Researchers have confirmed that by using a modified Wi-Fi router and several wireless devices in the living room, users can manipulate their electronic gadgets and home appliances by gesturing in any room in the home. The use of wireless signals for gesture recognition eliminates the need to deploy more sensors.
