International developers have been waiting patiently to buy Samsung’s Gear VR mobile headset internationally ever since the US release on December 8th. Many of them have their virtual reality applications ready to go, yet they have no way to test them without a way to purchase the headset. That was at least until a developer in Australia plugged an Oculus Rift DK1 controller box into the Galaxy Note 4 (the phone that powers the Gear VR headset).

Mark Schramm (co-creator of VR Bits) was sitting at home one day at the end of 2014 wondering how he was going to test his company’s new Gear VR demos. So instead of waiting for Samsung and Oculus to figure out an international release date, Schramm started experimenting with other possible options. He began by stripping down one of his extra DK1 headsets, removing the controller box and connecting it to the Note 4. Surprisingly, he found that the phone correctly recognized the headtracking sensor in the DK1.

From there, Schramm ordered a developer board covered in sensors (including an IMU) and flashed firmware onto it. This was done with the help of already established Github code that took information learned from the open-sourcing of the Oculus DK1 headset. After that, the board was mounted to a Google Cardboard VR smartphone adapter. With the Note 4 placed into Cardboard, and a strap attached, a Gear VR clone, capable of testing VR applications without Gear VR itself, was born.

Schramm documented the entire process through some videos. In addition, all the steps were posted on a website aptly called Open-Gear.com. Since then, a couple of other developers across the globe have created their own Gear VR clones.

There is a great video of a ping pong game between the official Gear VR and the cloned version. In it Schramm and a few other VR enthusiasts test out the tracking differences between the two devices by using the pass through camera. It is a joyfully fun experience to watch. (Spoiler: the real Gear VR still wins).

Although this is a cool project that can allow developers without the Gear VR headset to begin testing their apps, it’s in no way meant to ‘compete’ with Samsung’s Gear VR. It is instead only meant to show that developers can clone the headset and test their apps while they wait for the official headset to get shipped to their doors. Because Open Gear is essentially only taking the information learned from the researchers and developers within Oculus, all the credit should go back to Oculus for the heavy lifting. Still, Mark Schramm showed that is indeed possible to access the Oculus Store without an official Gear VR, which is definitely worth applauding.

However, the Gear VR clone has are some crucial limitations. For instance, as the Open-Gear website states, “Open Gear does not seem to trigger the switch into the low persistence mode of the screen correctly (even though it should).” The folks behind Open Gear are working to properly enable low persistence, which greatly reduces blur introduced by the display when the user moves their head.

In addition, the “tracker has a much lower update frequency, [so] you wouldn’t get the buttery smooth 1000Hz of the real thing, but it is enough for app testing.” Even more notably, there is no touchpad on the clone which reduces interactivity with some of the VR experiences; but any Bluetooth controller can be synced to the phone as a workaround.

Open Gear is a mere stepping stone for app testing, and nothing more (for now).

If you are interested in cloning your own Gear VR for testing an app, the steps are actually relatively straightforward. The Open Gear website lays out the steps:
