aframe Controls (component) 3Dof and 6Dof controllers
Example
Adding 3DoF Controllers
Controllers with 3 degrees of freedom (3DoF) are limited to rotational tracking. 3DoF controllers have no positional tracking meaning we can’t reach out nor move our hand back-and-forth or up-and-down. Having a controller with only 3DoF is like having a hand and wrist without an arm. Read more about degrees of freedom for VR.
The 3DoF controller components provide rotational tracking, a default model matching the real-life hardware, and events to abstract the button mappings. The controllers for Google Daydream and Samsung GearVR have 3DoF, and both support only one controller for one hand.

Daydream controllers
The daydream-controls component interfaces with the Google Daydream controllers. It wraps the tracked-controls component while adding button mappings, events, and a Daydream controller model that highlights the touched and/or pressed buttons (trackpad).
Match Daydream controller if present, regardless of hand.
<a-entity daydream-controls></a-entity>
Match Daydream controller if present and for specified hand.
<a-entity daydream-controls="hand: left"></a-entity>
<a-entity daydream-controls="hand: right"></a-entity>
GearVR-controllers
The gearvr-controls component interfaces with the Samsung/Oculus Gear VR controllers. It wraps the tracked-controls component while adding button mappings, events, and a Gear VR controller model that highlights the touched and/or pressed buttons (trackpad, trigger).
<!-- Match Gear VR controller if present, regardless of hand. -->
<a-entity gearvr-controls></a-entity>
<!-- Match Gear VR controller if present and for specified hand. -->
<a-entity gearvr-controls="hand: left"></a-entity>
<a-entity gearvr-controls="hand: right"></a-entity>
Adding 6DoF Controllers
Controllers with 6 degrees of freedom (6DoF) have both rotational and positional tracking. Unlike controllers with 3DoF which are constrained to orientation, controllers with 6DoF are able to move freely in 3D space. 6DoF allows us to reach forward, behind our backs, move our hands across our body or close to our face. Having 6DoF is like reality where we have both hands and arms. 6DoF also applies to the headset and additional trackers (e.g., feet, props). Having 6DoF is a minimum for providing a truly immersive VR experience.
The 6DoF controller components provide full tracking, a default model matching the real-life hardware, and events to abstract the button mappings. HTC Vive and Oculus Rift with Touch provide 6DoF and controllers for both hands. HTC Vive also provides trackers for tracking additional objects in the real world into VR.

Vive controllers
The vive-controls component interfaces with the HTC Vive controllers/wands. It wraps the tracked-controls component while adding button mappings, events, and a Vive controller model that highlights the pressed buttons (trigger, grip, menu, system) and trackpad.

Oculus touch controllers
The oculus-touch-controls component interfaces with the Oculus Touch controllers. It wraps the tracked-controls component while adding button mappings, events, and a Touch controller model.
