                            <!-- Basic Tutorial -->

<!-- You can bind the sensor data to the variables for gravity sensor, orientation sensor,
acceleration sensor, linear acceleration sensor and pressure sensors(altitude) -->

<!-- Example: -->

    <VariableBinders>
    <!--   Orientation sensor:
           type = "orientation"
           index = 0: azimuth, from 0 to 359, 0 = North, 90 = East, 180 = South, 270 = West.
           index = 1: pitch angle, -180 ~ 180, z-axis steering y-axis positive direction
           index = 2: roll angle, -90 ~ 90, x-axis steering z axis positive direction -->

        <SensorBinder type = "orientation">
            <Variable name = "orientation_x" index = "0" />
            <Variable name = "orientation_y" index = "1" />
            <Variable name = "orientation_z" index = "2" />
        </SensorBinder>

    <!--   Linear acceleration
           type = "linear_acceleration"
           index = 0: x direction of linear acceleration
           index = 1: y direction of linear acceleration
           index = 2: z direction of linear acceleration
           Linear acceleration is to remove the influence of gravity:
                 * linear acceleration = acceleration - acceleration due to gravity-->

        <SensorBinder type = "linear_acceleration">
            <Variable name = "linear_acceleration_x" index = "0" />
            <Variable name = "linear_acceleration_y" index = "1" />
            <Variable name = "linear_acceleration_z" index = "2" />
        </SensorBinder>

    <!--   Acceleration
           type = "accelerometer"
           index = 0: x direction acceleration
           index = 1: y direction acceleration
           index = 2: z direction acceleration -->

        <SensorBinder type = "accelerometer">
            <Variable name = "acceleration_x" index = "0" />
            <Variable name = "acceleration_y" index = "1" />
            <Variable name = "acceleration_z" index = "2" />
        </SensorBinder>

    <!--   Gravity sensor
           type = "gravity"
           index = 0: gravitational acceleration in the x direction
           index = 1: gravitational acceleration in the y direction
           index = 2: gravitational acceleration in the z direction -->

        <SensorBinder type = "gravity">
            <Variable name = "gravity_x" index = "0" />
            <Variable name = "gravity_y" index = "1" />
            <Variable name = "gravity_z" index = "2" />
        </SensorBinder>

    <!--   Pressure sensor
           type = "pressure"
           index = 0: barometric pressure unit hPa. The average air pressure at sea level is 1013.25hPa,
                      it can be estimated based on the barometric pressure altitude. -->

        <SensorBinder type = "pressure">
            <Variable name = "pressure" index = "0" />
        </SensorBinder>
