[DIY] HMD with Wide FOV and Stereoscopic
Posted: Tue Jan 18, 2011 7:37 am
Hello,
My Name is Marc. I'm french (so don't blame me if my english is not so good
)
I'm interested a lot on Virtual Reality, but, as everyone interested in VR , I'm a little bit disapointed that there is no really great HMD on the market. (I mean at consumer level)
I tried a lot of HMD for understanding which way was the best way to go.
What is really important with a HMD ? What do I need to feel Immersion ? What is the price to paid to have something good ?
Of course, it exist a lot of descent HMD on the market , but what everyone expect (Wide FOV , godd quality pictures, good headtracking and of course STereo 3D easily supported) is not going to happen nowadays. We'll have to wait a little.
So I decided to Build a Optical Box , containing screens, optical stuff, and one day I'll find a way to fix this box on some kind of plastic helmet to have a real HMD.
My work is not finished, but I wanted to share what I've done already.
1 - The global look of the optical box (at this time only one screen is working because I miss a second universal power supply) 2 - Getting closer to the right screen to see what we can see inside 3 - Closer again For that "first optical box try" i used :
- 2 x 3,5 LCD screen found on eBay (it cost me almost 20$ by screen) => They are not so good, but One day better screen from this size will be cheaper.
- Balsa Wood for the "box" to carry everything (not a very good choice , because balsa is very easy to break) => Around 10$ for 2 piece of 1m
- 2 PVC Coupler (almost 6$ on any store)
- All optics needed as shown on the very good tutorial http://www.vrtifacts.com/hmds/leep-on-the-cheap/" onclick="window.open(this.href);return false;
=> It's perfect to achieve some kind of LEEP Optics easily.
So with this box , I was able to Get Dual Input Stereoscopy (with IZ3D In dual projector mode)
Field of view is something around 100° (maybe a little bit less) so it's very nice !
Of course the Box is heavy , But I think this issue can be solved by mounting everything on a plastic helmet, and putting all the wires on the back (to counterbalance the weight)
My Next improvments will be :
- Get a better Box to fit everything inside (I Think I can reduce the box size)
- Change the material for making the Box => No idea at this moment ....
- Add a HeadTracking inside the box (for that it's easy => Using a Gyration GyroMouse will provide a 2DOF HeadTracking for cheap) => Maybe also a FreeTrack support by adding LED on the Box ...it will extend the HT capabilities
- Get Better LCD => Any Idea ?
Have a Nice a day ,
Marc.
