非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

DeviceMotionEvent 构造函数创建新 DeviceMotionEvent .

句法

var deviceMotionEvent = new DeviceMotionEvent(type[, options])
					

参数

type

Must be "devicemotion" .

选项 可选

Options are as follows:

• acceleration : An object giving the acceleration of the device on the three axis X, Y and Z. Acceleration is expressed in m/s ² .
• accelerationIncludingGravity : An object giving the acceleration of the device on the three axis X, Y and Z with the effect of gravity. Acceleration is expressed in m/s ² .
• rotationRate : An object giving the rate of change of the device's orientation on the three orientation axis alpha, beta and gamma. Rotation rate is express in degrees per seconds.
• interval : A number representing the interval of time, in milliseconds, at which data is obtained from the device.
