無線在2013國際CES上占據中心地位

　　國際消費電子展（CES）經常被用來作為一個對于行業的認可和各種無線標準的熱情的領頭羊。在今年的CES上，無線解決方案采用藍牙、NFC、ZigBee、Z-Wave、和Wi-Fi是無所不在的藍牙接口，此前幾乎專門用于手機耳機，擴大其滾到健身和醫療產品，計算機外圍設備，如鍵盤和鼠標，音響配件如無線立體聲耳機，遙控器，玩具，和其他產品。

　　然而，藍牙并不是孤立的——許多解決方案是耦合藍牙和近場通信（NFC）設備，以消除連接藍牙耳機或外圍設備到主機系統所需的繁瑣配對過程。通過結合NFC和藍牙，供應商已經使配對過程非常簡單——只需“輕拍”（將藍牙設備帶到NFC支持的主機系統的1或2厘米之內），NFC接口提供對主機系統的配對握手。隨著越來越多的手機供應商在他們的手機中加入NFC接口，這種方法越來越受歡迎。

　　藍牙在便攜式健康和健身相關產品中的應用正在加速。在CES上，一些新穎的產品提供了一些令人印象深刻的能力。例如，從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.
