Exercise HMD: Update

Since I first presented it a few weeks ago, the exercise HMD concept has adapted and grown up a bit.  The mask portion is made from Kydex, a far more versatile material.  There is still a removable foam liner.  With regard to lens fogging, I’ve used a tiny bit of anti fog coating that I had lying around for my diving mask and it pretty much alleviates any fogging issues.

NY’s TotalCinema360: Turning Heads on Both Coasts

Total Cinema 360 is NY’s own full service 360 degree, virtual reality video production company.   The NY VR Meetup has been lucky enough to try out some of TC360’s demos.  My personal favorite was the kitten cam in which a bunch of young cats were frolicking around the camera (Kitten POV!)  It seems that Adrian and Alex have been making the rounds and impressing people along the way.  Here’s a link to a recent interview they did and a link to their website.  Come to the next VR Meetup and see for yourself!

NY Virtual Reality Collective on Pix 11 Morning Show

Whatever your opinion on the recent Facebook acquisition of Oculus VR, one tangible benefit already trickling down to the VR community is heightened awareness of VR as an important technology area.  As a result of this heightened interest, I got a call from Kori Chambers of the PIX 11 Morning Show.  Kori is a professed VR enthusiast and invited me onto the show to do a demo of the Oculus Rift and talk a bit about VR.  While I had nightmares of projectile simulator sickness and uncooperative technology, everything went great and I think the segment came out well.  I hope that awareness and interest in VR continues to grow and we continue making NYC a center of the virtual reality world.

Sport / Hygienic Interface for Head Mounted Display

One of the important aspects of creating a comfortable VR experience is, well… creating a comfortable VR experience.  Towards this end I have developed a hygienic interface for a HMD that increases user comfort and hygiene.  I originally started this project over a year ago as a way to develop an HMD adapted for use during exercise.  My goal was to create a way to securely fasten the HMD to the face/head of the user as well as deal with user sweat.  

As I moved forward with the project I realized that it may have broader applicability to HMD’s generally.  For example, I plan on using the one-piece foam liner with a removable neoprene insert for future demonstrations of the Rift so that I can clean it between each use.  

Here are 2 embodiments that I have been playing with: the first utilizes a mask and a liner wherein the mask attaches to the user’s face and the HMD attaches to the mask using magnets.  The second is a removable foam liner that fits over the facial contact region of the HMD and stays in place due to friction.  In these experiments I have used the intermediate portion of the Oculus Rift HMD with the foam removed.

I am considering running a Kickstarter project to move the project forward.  I would appreciate if you would respond to the poll at the end of this post to indicate your interest.  Any additional feedback is also welcome.  Thanks!

HMD Mask with Liner:

This is the mask portion of the system.  The user facing side has foam posts adapted to fit into holes in a neoprene liner that can absorb and divert user sweat.  It is also easy to replace or substitute with other liners made of other materials.  The mask attaches to the user’s head using elastic straps (not shown.)

The neoprene liner fits on the inside surface of the mask and attaches by means of foam posts that fit snugly into holes on the neoprene liner.

This is the intermediate portion of the Oculus Rift HMD with the foam removed.  Magnets are installed on its surface and correspond to magnets installed on the mask to secure the mask to to the HMD.

Shown above is the mask attached to the intermediate portion of the HMD using magnets to hold the mask in place.  A groove on the mask corresponds to the inside surface of the intermediate portion of the Rift and allows for an exact fit.

Shown above is the mask with the neoprene liner attached.

One Piece Detachable Foam Liner:

This is the one piece foam liner that fits over the inside edge of the intermediate portion of the Oculus Rift HMD.  The snug fit allows the liner to stay in place by friction.  Alternatively magnets or other fixative may be used to secure the liner to the HMD.

20140224_180028

This is the inside surface of the HMD liner shown with one layer of the original Oculus Rift foam attached.  Alternatively additional layers of neoprene or other material may be used.  For example, a closed cell foam may be preferable as it can be wiped down with alcohol for increased hygiene.  The additional foam layers may be removably attachable by magnets, velcro or other fixative.

Rigorous testing of the the mask and liner shows no interference with the operation of the Oculus Rift.  In my opinion the liner and mask make for increased comfort as the Rift is more securely fixed to the user’s face.  Future directions include experimenting with other materials such as Kydex and various foams.  I’m very excited to keep working on this project as I believe a comfortable and clean user contacting portion of the HMD is going to be critical for mainstream adoption of VR technology.

First Meeting of NY Virtual Reality Collective

The NY Virtual Reality Collective held its first meeting on February 6th in midtown Manhattan and it was a great success.  We had about 10 people show up eager to show off their projects and discuss the coming age of VR.  James Andrew was kind enough to bring his Oculus Rift rig and everyone was able to have a chance to experience the unprecedented immersion the Rift enables.  We are looking forward to our next meeting which will be held on March 6th at a location to be determined.  I hope to see you there!
