Gyroscope
The Gyroscope
interface of the Sensor APIs provides on each reading the angular velocity of the device along all three axes.
To use this sensor, the user must grant permission to the 'gyroscope'
device sensor through the Permissions API. In addition, this feature may be blocked by a Permissions Policy set on your server.
Constructor
Gyroscope()
-
Creates a new
Gyroscope
object.
Instance properties
Gyroscope.x
Read only-
Returns a double, containing the angular velocity of the device along the device's x axis.
Gyroscope.y
Read only-
Returns a double, containing the angular velocity of the device along the device's y axis.
Gyroscope.z
Read only-
Returns a double, containing the angular velocity of the device along the device's z axis.
Instance methods
Gyroscope
doesn't have own methods. However, it inherits methods from its parent interfaces, Sensor
and EventTarget
.
Events
Gyroscope
doesn't have own events. However, it inherits events from its parent interface, Sensor
.
Example
The gyroscope is typically read in the reading
event callback. In the example below this occurs sixty times a second.
js
let gyroscope = new Gyroscope({ frequency: 60 });
gyroscope.addEventListener("reading", (e) => {
console.log(`Angular velocity along the X-axis ${gyroscope.x}`);
console.log(`Angular velocity along the Y-axis ${gyroscope.y}`);
console.log(`Angular velocity along the Z-axis ${gyroscope.z}`);
});
gyroscope.start();
