An anonymous reader writes "At CES 2015 this week, computer peripheral maker Razer and HMD maker Sensics joined forces to launch the 'OSVR' (Open Source Virtual Reality) project which includes an open source SDK and an open source $199 VR headset called the HDK (Hacker Developer Kit) (http://www.roadtovr.com/razer-hacker-dev-kit-osvr-sensics/). The headset will sport a 1080p display, 90 degree field of view, and 3DOF headtracking; it is expected to ship in June. Razer and Sensics say that the headset was built to be modular and hackable, making it easy to 3D print a custom front cover or drop in a higher resolution display, for example. The companies say that schematics for the headset will be made freely available, licensed so openly that someone could even opt to manufacture and sell their own VR headset based on the plans. The OSVR SDK is designed to be compatible with number VR headsets and peripherals so that developers can write once to support a wide range of devices."
