Guidelines for integration of the 3dRudder

The 3dRudder is a powerful VR motion controller that enables 360° of free motion powered by your feet. This page provides you with key recommendations to turn your integration of the 3dRudder into a success.

1. Direction of movement: the 3dRudder rules

Consider the 3dRudder as the legs that will move your VR body.
No matter the type of VR experience you develop (FP, flight simulation, etc.):

  • feet / 3dRudder = direction of movement
  • eyes / headset = sight
  • hands / controllers = interaction

You move in the direction your feet are going, not where you look at or where your hands point at. Implementing eye- or hand-oriented movement will both cause motion sickness and disorient the user.

2. Free rotation: a must-have

Free rotation is one of the most wanted feature in VR and it’s natively supported by the 3dRudder.
Implementing 3dRudder’s free rotation enables:

  • precise rotation control to within one degree
  • small rotation as well as full 360° turnarounds in any direction

Make sure to select a rotation speed similar to one you’d have in real life. Keep in mind that too quick a rotation may induce motion sickness.

3. Take advantage of 3dRudder's progressivity

The 3dRudder is the only VR controller to offer progressivity on 4 axes. It means users are empowered with the ability to speed up and slow down, in every direction, with very fine speed controls.
To implement this exclusive feature, you can set up:

  • acceleration
  • max speed
  • independently for each of the 4 axes

4. Dead zone: make it fit your experience

Dead zone is the angle or pressure you must give the 3dRudder to trigger motion: it must provide both confort and reactivity.
Set it up according to your experience:

  • null or low dead zone = high reactivity for fast-paced games
  • higher deadzone = comfort of use for more relaxing experiences

Dead zone can be set up independently for each axis.

5. Up and down: the exclusive feature

The 3dRudder is the only VR controller that offers the up/down axis. This axis is also progressive and combinable with the 3 others.
Use it for all kind of VR locomotion:

  • 3-dimensional locomotion: to fly, hover over (progressive)
  • 2-dimensional locomotion: to kneel down/stand up, jump (progressive or on/off)

6. Height in the game: seated or standing?

As the 3dRudder is used seated, tracking of the headset during calibration will indicate a low height in your VR experience.

Your VR experience is at standing height:

  • make sure you apply an offset value so that the user is not dwarfed by other characters or objects.
  • activate the up/down axis to enable kneeling down/standing up (ie. to grab objects on the floor) to allow the same range of motion as a standing user.

Your VR experience is at seated height: you’re good to go!

7. Activation/deactivation: make it automatic

The 3dRudder is a plug & play device. Users expect the same ease of use in your VR application.

  • Enabling: enable the 3dRudder automatically right when your VR experience starts. Don’t make users have to enable it manually.
  • Activation: the 3dRudder takes control of motion as soon as the user puts his feet on it (action can start)
  • Deactivation: the 3dRudder yields control as soon as feet are removed (action should stop). Freeze your application when the user takes his feet off the 3dRudder, unfreeze it when the user puts his feet back on again.
