+
+<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>
