慣性傳感將決定未來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量單元（IMU），結(jié)合陀螺儀，加速度計，磁力計和壓力傳感器都是在高級的游戲和工業(yè)應(yīng)用，尋找新的生活，如機(jī)器人和自動化系統(tǒng)。

　　慣性傳感器檢測和測量加速度，傾斜，沖擊，振動，旋轉(zhuǎn)和多自由度（DOF）運(yùn)動。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)，其中加速度計和陀螺儀所提供的測量跟蹤的對象的位置和方向相對于一個已知的起始點(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.
