Wireless Oculus Rift

While the Oculus is a great Head Mounted Display it's cord occasionally gets in the way and can become a noose or tripping hazard. Yell

So using some off the self parts the Oculus can be made wireless. This solution requires no soldering or modification of any of the electronics so its pretty easy to setup once you have the parts.

The setup is made of 3 components:

  • A Wireless HDMI Transmitter and Receiver 
  • A Portable USB Charger
  • A Wireless USB Kit

The Wireless HDMI is a Nyius ARISE Pro

The two portable chargers are a Rosewill 10000mAH and a RAVPower Element 10400mAh

The devices can all be powered with a Type M Barrel power cables with a few adapters that came with the Rosewill charger

Then there is the Cables Unlimited USB-WR2000 Wireless USB Kit (No link as the page it was purchased from no longer exists. Look at further reading for alternatives)

 

Review and Notes

The system performs fairly well even with 3 independently wireless devices communicating with the same computer. The wireless USB does add noticeable latency to the Oculus Rift.

First thing that was disappointing about the Nyruis Aries is that while it does have USB HID support it really mean it can support a mouse, keyboard, and simple Joysticks. The Oculus Rift and other devices like an Xbox 360 controller will show up as devices but do not function properly. The wireless HDMI is low latency but the product does lie about being "uncompressed video and audio". The system does compress the video feed and it has motion artifacts when turning. However due to the low resolution of the Oculus the effect seems less noticeable. Both parts of the system get VERY hot after a few minutes of use. I bought a HDMI extension cable to keep the dongle away from the video card's exhaust fan as I'm pretty sure it wasn't helping the situation. However no matter how hot the components got they always seemed to work. The range of the system is pretty good, I needed to be on another room for the signal to get lost.

The two battery packs were likely unnecessary. A splitter for the rift and the wireless USB may have worked by itself but I have not tested this yet. The Rosewill battery pack features 9v and 12v power as well as the 5v USB charging and it came with a bunch of accessories. By some luck all the adapters needed for the setup were included, the 9v/12v uses a cord the same as size as the Rift's power. The batteries were originally purchased to charge phones and tablets at conventions, they are much larger than necessary to power the system. Even after using the Rift wireless for 2 hours the batteries were only down about a third.

The Cables Unlimited USB-WR2000 Wireless USB Kit was purchased while ago for a separate project but it does help fix the issue of the wireless HDMI's HID failing to work for the Rift. As stated before it does add some latency to the head tracking but overall gets the job done. For previous experiments wireless 3-Space Sensors were used to replace the lack of wireless tracking.

The additional components to make the Oculus Rift Wireless weighed in at only 836g and after a few minutes of play was unnoticeable. The lack of a cord made it much easier to interact with the virtual world without being worried about tripping or being pulled by the cord. Even though the bag holding the system was shaken around quite a bit nothing lost power for the session.
