The '''Leap Motion Controller''' is an optical [[hand tracking]] input device originally developed by [[Leap Motion]] (now [[Ultraleap]] after a 2019 acquisition), first released on July 22, 2013, at $79.99. The controller pioneered consumer-grade hand and finger tracking using a small USB peripheral with dual near-infrared cameras and infrared LEDs, enabling users to interact with computers and virtual environments using natural hand gestures without wearing gloves or touching surfaces. The device captures the movement of hands and fingers within a 3D interactive zone extending up to 60-80cm with a 140° × 120° field of view, operating at 120Hz (capable of 200Hz) with image capture speeds as fast as 1/2000th of a second. The sophisticated software discerns 27 distinct hand elements including bones and joints, tracking them even when partially obscured. Originally designed for desktop computing, the Leap Motion Controller found significant adoption in VR/AR applications when mounted to headsets, becoming a standard for hand tracking in applications like VRChat, medical visualization, and industrial training. The second-generation Leap Motion Controller 2 (2023) features Ultraleap's Hyperion tracking software with sub-millimeter precision, while the Stereo IR 170 (formerly Rigel) offers an even wider field of view and longer range for enterprise applications.
