Virtual reality (VR) headset maker Oculus has acquired Nimble VR and 13th Lab to enhance its 3D technology and make the devices more responsive to gestures.

Founded in 2012, Nimble VR develops machine learning and computer vision for skeletal hand gesture tracking with 3-D cameras. It is expected to enhance the VR experience for users by mounting the camera on top of the Oculus Rift.

13th Lab develops efficient and accurate real-time 3D reconstruction framework. It also uses advanced cameras to recreate physical environments in 3D.

Apart from the two startups, Oculus has also roped in motion capture expert Chris Bregler who has worked in Academy Award nominated movies.

Chris also served as a professor of Computer Science at New York University and at Oculus he is expected to lead a vision research team of the company.

Oculus said: "Nimble VR, 13th Lab, and Chris will all be winding down their existing projects to focus on VR full-time at Oculus as part of both product engineering and Oculus Research."

The Facebook owned headset maker did not reveal the financial details of the acquisition.
