Set up your Ultraleap Stereo IR 170 Evaluation Kit for VR headsets

If you haven’t already downloaded the SDK, please go back and do this first.

1. 3D print Stereo IR 170 Evaluation Kit Mount

If you have access to a 3D printer, we recommend downloading and printing the free Stereo IR 170 Evaluation Kit Mount.


2. Attach mount and Stereo IR 170 Evaluation Kit to VR headset

If using the 3D printed mount, attach in the centre of the headset and insert the Stereo IR 170 Evaluation Kit. Otherwise, we recommend using a small strip of velcro in the same position.

For optimum viewing experience, the Stereo IR 170 should be tilted downwards by 15° so that the user’s natural hand position is in the centre of the hand tracking device’s field of view. This will ensure users’ entire natural interaction area is visible and can be tracked.

The Stereo IR 170 operates with a typical horizontal and vertical field of view of 170° x 170° and a depth of reliable tracking of 10cm to 75cm.


3. Remove both lens caps from the Stereo IR 170 Evaluation Kit


4. Plug the Stereo IR 170 Evaluation Kit into your VR headset

Use the USB cable included in the box.

⚠️ If using a DS-2 VR headset, please use a USB port on the computer, rather than the built-in USB port.

5. If using an Oculus headset, enable external apps

⚠️ If using an Oculus VR headset, you must enable it to run applications outside of Oculus Home.

From the Oculus App Settings, check Unknown sources.


6. Run the Leap Motion Visualizer

Run the Leap Motion Visualizer to check your device is working properly. This can be found in the Leap Motion Control Panel.
