　　一旦沦为航空航天应用，如高度和航向参考系统，惯性传感器，经常发现在高度集成的惯性测量单元（IMU），结合陀螺仪，加速度计，磁力计和压力传感器都是在高级的游戏和工业应用，寻找新的生活，如机器人和自动化系统。

　　惯性传感器检测和测量加速度，倾斜，冲击，振动，旋转和多自由度（DOF）运动。直到最近，他们的主要用途是在惯性导航系统（INS）作为导航技术，其中加速度计和陀螺仪所提供的测量跟踪的对象的位置和方向相对于一个已知的起始点，方向和速度。它们被应用于飞机、战术和战略导弹、宇宙飞船、潜艇和舰船等大型应用中。

　　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.
