The lenses are quite different as compared to the flannel Lenses from the Rift and Vive. Razer offers

a dual lens system. The problem with these lenses is that they give a slightly distorted picture. It’s like you’re viewing underwater. Another issue with the dual lenses is the weight, they are much heavier than the flannel lens. The field of view is fine, though I clearly see the edges of the plastic case.

IR positional tracking camera:

The positional tracking camera can cover a viewing area of nearly 2.4 to 2.7 meters. That’s acceptable for standing experience, but walking around is not an available option. However, you can go full 360 degrees on account of a box with IR LEDs that is positioned behind the headset. There are a lot of improvements needed in the tracking system. The camera too doesn’t follow smoothly. If Razer is able to fix this, the OSVR can be a serious innovation.


In Action

You can find the Runtime Setup comprising of all the important drivers, software, tools and scripts on the website www.osvr.org. After this smooth installation, you can start using the HDK2. Before you start an application you will have to start the OSVR server. This can be done by clicking on the OSVR system tray icon. The OSVR Server is the core of the Runtime software and accountable for several functions such as communications between hardware and software and the loading of plug-ins. Before initializing the OSVR server for the first time, you have to apply some configuration in the OSVR control panel.

Gaming and Game Engine Support:

Although this headset isn’t manufactured for the mainstream gamer, it’s nice to know that it is compatible with Steam VR. In order to use the headset with steam, you have to configure Steam first. On the YouTube channel RTPC Mod Life you can discover a vast collection of guides for HDK and also an excellent guide on how to add the OSVR driver to Steam. It’s another extra step before you can use the HMD.

For professional developers OSVR assists many game engines including Unity and different operating systems. Everything resides under the free Apache 2.0 license. It is uncomplicated to integrate the HDK with your current projects. Razer issued several tutorials for this and there also many YouTube tutorials available.


The OSVR headset really can’t be simply compared as a tough competitor to the Oculus Rift or the HTC Vive at all yet. The device is distinctly Razer in the context that it’s trying to make VR an open source platform for everyone to create their own VR hardware. Still the Razer OSVR has a long way to go before it can truly be categorized in the same league as the HTC Vive, Oculus Rift or Project Morpheus.
