昨日谷歌大会上演示了Chromecast一项新的功能，只要在同一个房间，不需要手动连接WiFi也就直接与Chromecast连接。

谷歌称，如果你想把手机和Chromecast连接起来，只需将打开电视就好了。这是一种新的WiFi配对技术，Chromecast会通过电视的喇叭发出超声波，超声波会被手机的听筒接收并识别，接收到超声波信号的手机就会自动的检测Chromecast，并加入它的WiFi网络，只要打开电视机的电源Chromecast将自动发送超声波，这样就可以做到电视与手机的无缝连接，这种连接是独立的不需要用户建立其他WiFi。

这个功能听起来有些古怪，不过从谷歌的演示来看非常的酷。
