System capability: SystemCapability.Sensors.Sensor

Parameters

Name Type Mandatory Description
rotationVector Array&lt;number&gt; Yes Rotation vector to convert.
callback AsyncCallback&lt;Array&lt;number&gt;&gt; Yes Callback used to return the quaternion.

Example

import sensor from '@ohos.sensor';
import BusinessError from '@ohos.base';

sensor.createQuaternion([0.20046076, 0.21907, 0.73978853, 0.60376877],
                        (err: BusinessError.BusinessError, data: Array<number>) => {
  if (err) {
    console.error(`Failed to register data. Code: ${err.code}, message: ${err.message}`);
    return;
  }
  for (let i = 0; i < data.length; i++) {
    console.info("Succeeded in getting data[" + i + "]: " + data[i]);
  }
})

sensor.createQuaternion(deprecated)

createQuaternion(rotationVector: Array&lt;number&gt;): Promise&lt;Array&lt;number&gt;&gt;

Converts a rotation vector into a quaternion. This API uses a promise to return the result.

This API is deprecated since API version 9. You are advised to use sensor.getQuaternion instead.

System capability: SystemCapability.Sensors.Sensor

Parameters

Name Type Mandatory Description
rotationVector Array&lt;number&gt; Yes Rotation vector to convert.

Return value

Type Description
Promise&lt;Array&lt;number&gt;&gt; Promise used to return the quaternion.

Example

import sensor from '@ohos.sensor';

const promise = sensor.createQuaternion([0.20046076, 0.21907, 0.73978853, 0.60376877]);
promise.then((data: Array<number>) => {
  console.info('Succeeded in getting createQuaternion_promise');
  for (let i = 0; i < data.length; i++) {
    console.info("data[" + i + "]: " + data[i]);
  }
}).catch((err: BusinessError.BusinessError) => {
  console.info(`Failed to get promise.`);
})

sensor.getDirection(deprecated)

getDirection(rotationMatrix: Array&lt;number&gt;, callback: AsyncCallback&lt;Array&lt;number&gt;&gt;): void

Obtains the device direction based on the rotation matrix. This API uses an asynchronous callback to return the result.

This API is deprecated since API version 9. You are advised to use sensor.getOrientation instead.

System capability: SystemCapability.Sensors.Sensor

Parameters

Name Type Mandatory Description
rotationMatrix Array&lt;number&gt; Yes Rotation matrix.
callback AsyncCallback&lt;Array&lt;number&gt;&gt; Yes Callback used to return the rotation angle around the z, x, and y axes.

Example

import sensor from '@ohos.sensor';
import BusinessError from '@ohos.base';

sensor.getDirection([1, 0, 0, 0, 1, 0, 0, 0, 1], (err: BusinessError.BusinessError, data: Array<number>) => {
  if (err) {
    console.error(`Failed to register data. Code: ${err.code}, message: ${err.message}`);
    return;
  }
  console.info("Succeeded in getting getDirection interface get data: " + data);
  for (let i = 1; i < data.length; i++) {
    console.info("Succeeded in getting sensor_getDirection_callback" + data[i]);
  }
})

sensor.getDirection(deprecated)

getDirection(rotationMatrix: Array&lt;number&gt;): Promise&lt;Array&lt;number&gt;&gt;

Obtains the device direction based on the rotation matrix. This API uses a promise to return the result.

This API is deprecated since API version 9. You are advised to use sensor.getOrientation instead.

const promise = sensor.getDirection([1, 0, 0, 0, 1, 0, 0, 0, 1]);
promise.then((data: Array<number>) => {
  console.info('Succeeded in getting sensor_getAltitude_Promise', data);
  for (let i = 1; i < data.length; i++) {
    console.info("Succeeded in getting sensor_getDirection_promise" + data[i]);
  }
}).catch((err: BusinessError.BusinessError) => {
  console.info(`Failed to get promise.`);
})

sensor.createRotationMatrix(deprecated)

createRotationMatrix(gravity: Array&lt;number&gt;, geomagnetic: Array&lt;number&gt;, callback: AsyncCallback&lt;RotationMatrixResponse&gt;): void
