Developer: Leap Motion
Created: June 17, 2016
Requires: Windows, Oculus Rift/HTC Vive

This virtual reality app requires the use of an HTC Vive or Oculus Rift, a mounted Leap Motion Controller (using the VR Developer Mount or unofficial alternative), and the Leap Motion Orion software.

Update (June 8, 2017): Detection Utilities functions are now best handled by the Interaction Engine (e.g. Camera-Facing Open Hand exists in example scripts in the Interaction Manager). Learn more on our blog.

Unlock new possibilities in your Orion project with Add-on Modules – powerful extensions built on top of our beta release of the Unity Core Assets for Orion. Learn more in our post Unity Core Assets 101: How to Start Building Your VR Project.


Thumbs up for detectors! These scripts provide a convenient way to detect what a user’s hand is doing. In addition to detecting pinches, you can detect when the fingers of a hand are curled or extended, whether a finger or palm is pointing in a particular direction, and whether the hand or fingertip are close to one of a set of target objects.

What’s more, these detectors can be combined together using a Logic Gate. The Detector Logic Gate is itself a detector that logically combines two or more other detectors to determine its own state. Need a thumbs up gesture? Combine a thumb-extended detector with a thumb-pointing-upward detector using a logic gate.

The Detection Examples contain example scenes illustrating how to use the Detector scripts added to Core Assets 4.1.1. These detector scripts expand on the Pinch Utility module, which has been rolled into the Core Assets and retired. You can learn more about Detectors on our blog or by looking at the scenes.

Please note: the Orion Add-on Modules are dependent on our beta Unity Core Assets for Orion and will not function properly without them.
