Wi-Fi Wobbling Hand Gestures Could Control Home
要关灯?做个拳击动作!
A system called WiSee would interpret hand gestures as gadget-governing instructions for any connected device in a home based on disruptions in ambient wi-fi signals.
我们的肢体动作能够改变房间中wi-fi信号的分布,从而遥控屋子里的任何电器。

Thanks to wi-fi we can watch movies, play games, and check e-mail, from the comfort of the couch. And soon we may be able to repurpose our wi-fi signals so we can turn on the coffeemaker or turn off the TV with a simple flick of a finger, from anywhere in the house. Researchers described their prospective system, called WiSee, at the International Conference on Mobile Computing and Networking.

因为有了wi-fi,就算窝在沙发里我们也能看电影、打游戏、查邮件。但wi-fi的用途远不止此:或许用不了多久,不论在房子里的任何地方,我们只需轻弹一下指尖,就能打开咖啡机或者关掉电视。研究人员在移动计算与网络国际会议上介绍了这一前瞻性的WiSee系统。
The idea is similar in concept to the Xbox Kinect, which uses cameras to recognize a game player’s movements, and translates them into an action onscreen. But WiSee works without cameras. Instead, it uses the ambient wireless signals put out by our smart phones, laptops, routers and tablets.
WiSee的原理类似于体感游戏机Xbox Kinect。体感游戏机利用摄像头识别玩家的动作,并将其投射到屏幕中的虚拟人物身上,但WiSee不需要摄像头,它利用的是周围智能手机、笔记本电脑、路由器和平板电脑发射的无线信号。
When we move, we alter the patterns of these wi-fi signals. The WiSee receiver detects these disturbances and interprets the motions that caused them, like waving or swinging your fists. Of 900 gestures tested, WiSee could identify 94 percent.
我们的动作会改变周围无线信号的分布。WiSee系统的接收设备能够探测到这些变化,并识别造成这些改变的动作,比如晃动拳头。研究人员用WiSee测试了900个手势,识别率高达94%。
The user assigns a particular motion to a specific gadget—the motion doesn’t have to be the one that works in the real world. So if all goes well, you may actually be able to punch your lights out.
用户可以给每个电器分配一个专门的手势,并且,这个手势不一定非得是你开关电器的那个动作。所以,如果一切顺利的话,你以后只需挥一下拳头,就能关掉房里的灯。
