<div>{{APIRef("WebVR API")}}{{SeeCompatTable}}</div>

<p>The <strong><code>VRPose</code></strong> interface of the <a href="/en-US/docs/Web/API/WebVR_API">WebVR API</a> represents the state of a VR sensor at a given timestamp (which includes orientation, position, velocity, and acceleration information.)</p>

<p><a href="/en-US/docs/Web/API/WebVR_API">WebVR API</a>  中的 <strong><code>VRPose</code></strong> 接口表示在一个给定的时间戳中，一个VR传感器的状态（包括了方向、位置、速度和加速度信息）。</p>

<p>This interface is accessible through the {{domxref("VRDisplay.getPose()")}} and {{domxref("VRDisplay.getImmediatePose()")}} methods.</p>

<p>这个接口能通过 {{domxref("VRDisplay.getPose()")}} 和 {{domxref("VRDisplay.getImmediatePose()")}} 方法访问</p>

 <dt>{{domxref("VRPose.linearAcceleration")}} {{readonlyInline}}</dt>
 <dd>Returns the linear acceleration of the {{domxref("VRDisplay")}} at the current {{domxref("VRPose.timestamp")}}, in meters per second per second.</dd>
 <dd>返回当前时间戳 {{domxref("VRPose.timestamp")}}  时 {{domxref("VRDisplay")}}  的线加速度，单位为米/平方秒。</dd>
 <dt>{{domxref("VRPose.orientation")}} {{readonlyInline}}</dt>
 <dd>Returns the orientation of the sensor at the current {{domxref("VRPose.timestamp")}}, as a quarternion value.</dd>
 <dd>以四元数的形式返回当前时间戳 {{domxref("VRPose.timestamp")}}  时传感器的方向，</dd>
 <dt>{{domxref("VRPose.angularVelocity")}} {{readonlyInline}}</dt>
 <dd>Returns the angular velocity of the {{domxref("VRDisplay")}} at the current {{domxref("VRPose.timestamp")}}, in radians per second.</dd>
 <dd>返回当前时间戳 {{domxref("VRPose.timestamp")}}  时 {{domxref("VRDisplay")}}  的角速度，单位为弧度/秒。</dd>
 <dt>{{domxref("VRPose.angularAcceleration")}} {{readonlyInline}}</dt>
 <dd>Returns the angular acceleration of the {{domxref("VRDisplay")}} at the current {{domxref("VRPose.timestamp")}}, in meters per second per second.</dd>
 <dd>返回当前时间戳 {{domxref("VRPose.timestamp")}}  时 {{domxref("VRDisplay")}}  的角加速度，单位为弧度/平方秒。</dd>
