The Leap Motion Controller from Ultraleap is an optical hand tracking module that captures the movement ofusers' hands and fingers so they can interact naturally with digital content. Small, fast, and accurate, the LeapMotion Control can be used for productivity applications with Windows computers, integrated into enterprise-grade hardware solutions or displays, or attached to virtual/augmented reality headsets for AR/VR/XR prototyping,research, and development.
The controller is capable of tracking hands within a 3D interactive zone that extends up to 60cm (24”) or more,extending from the device in a 120×150° field of view. Leap Motion‘s software is able to discern 27 distinct handelements, including bones and joints, and track them even when they are obscured by other parts of the hand.With a 120Hz refresh rate and low-latency software, the time between motion and photon falls beneath thehuman perception threshold.
An accessory component, the VR Developer Mount, allows for easy, reliable, and consistent attachment of thedevice to virtual reality headsets such as the Oculus Rift and HTC Vive. The Leap Motion App Gallery features 75+legacy desktop applications and a demo suite for virtual reality.
