Leap Motion

Leap Motion is a hand and gesture tracking controller that uses infrared technology to detect and interpret hand movements and finger positions in 3D space. The device connects to a Mac via USB and enables touchless control of applications, immersive VR/AR experiences, and gestural interfaces. It was popular among developers, creative professionals, and VR enthusiasts who wanted to add natural hand interaction to their workflows. The Leap Motion service provides the companion software, drivers, and SDK needed to run supported applications with hand-tracking capabilities.
