==Introduction==
The [[OSVR HDK2]] or '''Hacker Dev Kit 2''' is a [[Virtual Reality]] [[head-mounted display]] created by [[Razer]] and [[Sensics]]. HDK2 is the [[OSVR]]'s second device. It was announced in E3 2016. OSVR HDK2 has an open source and modular design that not only allows the user to replace and renew its hardware components but also build one from scratch.


OSVR HDK2 went on sale on July 29, 2016 at the price of $399. Students and developers can apply to receive 20% discount.
The '''OSVR HDK 2''' (Hacker Development Kit 2) is an open source [[virtual reality]] [[head-mounted display]] developed by [[Razer]] and [[Sensics]] as part of the Open Source Virtual Reality (OSVR) initiative. Announced at E3 2016 and released on July 29, 2016 at $399, the HDK 2 features dual OLED displays at 1080 x 1200 per eye, 90 Hz refresh rate, 110-degree field of view, and custom SLR-grade dual lenses free from god rays. The open source and modular design allows users to replace components and even build the headset from scratch. The HDK 2 supports native OSVR experiences, SteamVR content, and WebVR.<ref name="razer">{{cite web|url=https://press.razer.com/product-news/osvr-launches-the-hdk-2-an-open-source-2160-x-1200-dual-display-vr-headset-in-the-asia-pacific-region/|title=OSVR Launches the HDK 2|publisher=Razer}}</ref>
__TOC__
==Hardware==
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.


===Display===
== History and Development ==
The OSVR HDK2 has a dual display that runs 90 frames / Second and has 2160 x 1200 pixels as its combined resolution. The OSVR HDK2 has a screen with 441-PPI, RGB-OLED display. To cut the screen effect OSVR had added a silver layer to the display.


===Lenses===
=== OSVR Initiative ===
[[HTC Vive]] and [[Oculus Rift]] use [[fresnel lense]]s; Razer has opted a different system. It uses a dual lens system. Even though the dual lens system isn’t perfect, it’s free from the [[godrays]] issue. Furthermore, the dual lens system is heavier than the fresnel lenses. The OSVR HDK2 headset has an 110-degree [[FoV]] (Field of View).  
OSVR (Open Source Virtual Reality) was founded by Razer and Sensics to create an open platform for VR development.


===Infrared Positional Tracking Camera===
=== E3 2016 Announcement ===
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 HDK 2 was announced at E3 2016 on June 13, 2016.


===Controllers===
=== July 2016 Release ===
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.
The HDK 2 went on sale July 29, 2016 at $399.

==System Requirements==
In this regard, Razer follows the footsteps of HTC Vive and Facebook. The PC that powers the OSVR HDK2 headset must have a graphic card that’s at least a Radeon R9 280 or NVIDIA GeForce GTX 970. The PC must use Intel Core i5-4590 or higher as the CPU. Finally, the PC must have at least one HDMI 1.3 port and two USB 2.0 port to connect the various cables from the headset.
 
==Setup Tutorial==
To begin with, connect the belt clip and the positional tracker to the PC using the USB port. Between the belt clip and the IR camera is a 3.5 mm mini-jack, and fixed to it is the adaptor jack. The VR headset is connected to one side of the belt clip. The belt clip has a spare USB port that can be used to connect accessories like [[Leap Motion]]. Among the cables, a 3.5 mm connector for headphones is also provided. Connecting the hardware components might look tedious, but with the manual in hand and little technical understanding, the task can be accomplished without much effort.
 
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 [[Interpupillary 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.
 
==Software==
The scripts, software, tools, and drivers needed to run the HDK 2 are on the official website (http://www.osvr.org/) of OSVR. Users can visit the website, download the installation setup and install the necessary software package in the PC.
