　　无线在2013国际CES上占据中心地位

　　国际消费电子展（CES）经常被用来作为一个对于行业的认可和各种无线标准的热情的领头羊。在今年的CES上，无线解决方案采用蓝牙、NFC、ZigBee、Z-Wave、和Wi-Fi是无所不在的蓝牙接口，此前几乎专门用于手机耳机，扩大其滚到健身和医疗产品，计算机外围设备，如键盘和鼠标，音响配件如无线立体声耳机，遥控器，玩具，和其他产品。

　　然而，蓝牙并不是孤立的——许多解决方案是耦合蓝牙和近场通信（NFC）设备，以消除连接蓝牙耳机或外围设备到主机系统所需的繁琐配对过程。通过结合NFC和蓝牙，供应商已经使配对过程非常简单——只需“轻拍”（将蓝牙设备带到NFC支持的主机系统的1或2厘米之内），NFC接口提供对主机系统的配对握手。随着越来越多的手机供应商在他们的手机中加入NFC接口，这种方法越来越受欢迎。

　　蓝牙在便携式健康和健身相关产品中的应用正在加速。在CES上，一些新颖的产品提供了一些令人印象深刻的能力。例如，从hapilabs1的hapifork

Additionally， it can also let you know if you are eating too fast via indicator lamps or vibrations. （Courtesy of HAPILABS.）

　　To capture this data， the grip handle of the HAPIfork contains an electronic key， Bluetooth and USB interfaces， and other circuits that are activated when the fork is held. When the fork is put in the mouth， the circuit is closed， and the fork reports one “bite.” The HAPIfork also provides alerts in the form of indicator lights and gentle vibrations when it determines you are eating too quickly. Included with the fork is a complete software suite that provides an online dashboard to store and display your eating related data， a coaching program to help you eat smarter， a fun online social game to motivate you to modify your old habits， and still other tools.
