const options = { frequency: 60, referenceFrame: "device" };
const sensor = new AbsoluteOrientationSensor(options);

sensor.addEventListener("reading", () => {
  // model is a Three.js object instantiated elsewhere.
  model.quaternion.fromArray(sensor.quaternion).inverse();
});
sensor.addEventListener("error", (event) => {
  if (event.error.name === "NotReadableError") {
    console.log("Sensor is not available.");
  }
});
sensor.start();

权限示例

使用方向传感器需要请求对多个设备传感器的权限。由于Permissions接口使用 Promise，因此请求权限的最佳方法是使用Promise.all。

const sensor = new AbsoluteOrientationSensor();
Promise.all([
  navigator.permissions.query({ name: "accelerometer" }),
  navigator.permissions.query({ name: "magnetometer" }),
  navigator.permissions.query({ name: "gyroscope" }),
]).then((results) => {
  if (results.every((result) => result.state === "granted")) {
    sensor.start();
    // …
  } else {
    console.log("No permissions to use AbsoluteOrientationSensor.");
  }
});
