慣性傳感將決定未來(lái)游戲控制器的工作方式

　　一旦淪為航空航天應(yīng)用，如高度和航向參考系統(tǒng)，慣性傳感器，經(jīng)常發(fā)現(xiàn)在高度集成的慣性測(cè)量單元（IMU），結(jié)合陀螺儀，加速度計(jì)，磁力計(jì)和壓力傳感器都是在高級(jí)的游戲和工業(yè)應(yīng)用，尋找新的生活，如機(jī)器人和自動(dòng)化系統(tǒng)。

　　慣性傳感器檢測(cè)和測(cè)量加速度，傾斜，沖擊，振動(dòng)，旋轉(zhuǎn)和多自由度（DOF）運(yùn)動(dòng)。直到最近，他們的主要用途是在慣性導(dǎo)航系統(tǒng)（INS）作為導(dǎo)航技術(shù)，其中加速度計(jì)和陀螺儀所提供的測(cè)量跟蹤的對(duì)象的位置和方向相對(duì)于一個(gè)已知的起始點(diǎn)，方向和速度。它們被應(yīng)用于飛機(jī)、戰(zhàn)術(shù)和戰(zhàn)略導(dǎo)彈、宇宙飛船、潛艇和艦船等大型應(yīng)用中。

　　Advances in MEMS technology， however， have enabled manufacture of small INS units， opening up their use in many more applications， including those involving motion capture. Gesture-recognition interfaces are a good example. Defined gestures， such as taps， double-taps， or shakes， allow users to activate different features or adjust the mode of operation of a game controller. In industry， gesture recognition also makes devices more usable where physical buttons and switches would be difficult to manipulate. Button-free designs can also reduce overall system cost in addition to improving the durability of end products， such as underwater cameras， where the opening surrounding a button would let water seep into the camera body.
