Gyroscope
interface returns a double precision integer containing the angular velocity of the device along the its z axis.
If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See
Feature-Policy
for implementation instructions.
var z = gyroscope.z
A
Number
.
The gyroscope is typically read in the
Sensor.onreading
event callback. In the example below this occurs sixty times a second.
let gyroscope = new Gyroscope({frequency: 60});
gyroscope.addEventListener('reading', e => {
console.log("Angular velocety along the X-axis " + gyroscope.x);
console.log("Angular velocety along the Y-axis " + gyroscope.y);
console.log("Angular velocety along the Z-axis " + gyroscope.z);
});
gyroscope.start();
