Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The GamepadPose interface of the Gamepad API represents the pose of a WebVR controller at a given timestamp (which includes orientation, position, velocity, and acceleration information.)
This interface is accessible through the Gamepad.pose property.
Properties
GamepadPose.hasOrientationRead only- Returns a boolean indicating whether the gamepad is capable of returning orientation information (
true) or not (false). GamepadPose.hasPositionRead only- Returns a boolean indicating whether the gamepad is capable of returning position information (
true) or not (false). GamepadPose.positionRead only- Returns the position of the
Gamepadas a 3D vector. GamepadPose.linearVelocityRead only- Returns the linear velocity of the
Gamepad, in meters per second. GamepadPose.linearAccelerationRead only- Returns the linear acceleration of the
Gamepad, in meters per second per second. GamepadPose.orientationRead only- Returns the orientation of the
Gamepad, as a quarternion value. GamepadPose.angularVelocityRead only- Returns the angular velocity of the
Gamepad, in radians per second. GamepadPose.angularAccelerationRead only- Returns the angular acceleration of the
Gamepad, in meters per second per second.
Examples
TBD.
