Virtual reality is the present and future. We are all going to be better off if there is an open source platform devices and VR software can rely on to work with other VR solutions on the market. OSVR (Open Source Virtual Reality) aims to address that. It is a standard for virtual reality devices and hardware. In fact, Razer has a Hacker Dev Kit with an accelerometer, gyroscope, and compass. You also get USB 3.0 ports, a 5.5″ FHD display (1080p), a near-eye-display system with field of view of 100 degrees, and a mobile phone holder.
Since this is an open source solution, you can download the 3D files and build your own virtual reality glasses. The kit ships in June 2015 for $199.99.
