The Open-Source Virtual Reality Hacker’s Development Kit (OSVR HDK) 2 is unlike any other virtual reality headset. The HDK2 kit comprises of the headset, belt clip, manuals, box adaptor, the positional tracker with a tripod, and a cluster of connecting cables and cleaning cloth.
===Infrared Positional Tracking Camera===
Razer’s infrared positional tracking camera has a maximum range of 2.4 – 2.7 meters. Although the IR camera of OSVR HDK2 is a good alternative to other tracking cameras, it has certain limitations. The infrared range is sufficient to track standing experiences. The camera’s performance might greatly suffer if the users walk around too much. The infrared LEDs on the rear end of the VR headset allow the camera to capture 360-degree turns.
The OSVR HDK2 Kit doesn’t come with a controller. Users are free to use any suitable controller with the HDK2 kit. Most developers find the Razer Hydra controller a better choice.
==Modules== ===Faceplate Module=== *The OSVR HDK2 kit comes with an IR camera *The Infrared camera operates at 100 Hz *The v1.4 infrared faceplate provides positional tracking *Some of the other variations included are the IR faceplate with Leap Motion.

After downloading, install the OSVR Server on the PC. Following the installation process and before running the OSVR Server for the first time, the user needs to configure the server in the control panel.
The OSVR Server is the most important element of the whole system. It’s the driving force behind the Runtime Software. It initiates and manages crucial functions such as loading of various plug-ins, communications between the software and hardware, and rendering the pipeline. To use any of the applications, users are supposed to start the OSVR Server first.
Through the control panel of the OSVR Server, a user can perform many functions including enabling the HMD, checking and upgrading the firmware, and adjust various other settings. Additionally, a user can also choose either the direct or extended mode, re-center the HDK2 headset, enter the interpapillary distance, and toggle side by side. When the direct mode is chosen, the software will communicate only with the virtual reality headset, whereas, in the case of the extended mode the VR headset acts as the supplementary display option.
