@Mark: I am working on it, I have already made some very high FOV versions. Pretty excited about what is possible with this! Shipping to Malaysia is no problem, as long as you pay for it. ;)

@Yolonegro, 3Dgirl, and TesterBoy: The game is up. You should be ashamed of yourselves!

Yolonegro, you register here and your first post just happens to be about the ToyIn3D. Your IP address traces to Madrid, Spain, the location of ToyIn3D. The very next day after you saw me pointing out the flaws in your design, you go to my employer and threaten legal action. Very classy. :roll:

3DGirl, you also happen to register at the same time, asking me for my lens source, claiming to be working for a charitable organization. I would have told you either way, but you seem to think that the only way to get ahead is to deceive others. Your IP also traces to Madrid, Spain.

TesterBoy, you also happen to register only to post about how great ToyIn3D is. You claim that you ordered four of them to Australia. Problem is, your IP not only traces to Madrid, Spain, it is the same IP address as 3DGirl! Explain how two people have the same IP address when one of them is in Australia and the other works in Africa? :|

You violate not only the rules of the forum (http://www.mtbs3d.com/phpBB/viewtopic.php?f=111&t=10449), but basic professional ethics. A company that uses these kinds of tactics should not be supported by anyone. My critique of your product is entirely factual, and if you disagree with it, then feel free to tell me why. Going behind my back without even defending your product is wrong, and lying to promote your product is even worse.

In light of this explanation, all "three" of you are banned. If you would like to talk about ToyIn3D here, then sign up for an account that clearly discloses that it belongs to your company.

Great spotting PalmerTech. TesterBoy was totally obvious, but the IP obviously gives away those other two rather well.

As you say, it shows a total lack of professional ethics. I'm tempted to post about this on Reddit about it so everyone can laugh (and be warned) about these guys....
They are obviously not very bright, but think they are. First posts by ANYONE that seem more like ads always attract my suspicion, and it seems they don't even have basic knowledge about IP addresses.

'3DGirl' (who is probably the same person) trying to pretend to be a charitable organization is exceptionally low.

I've been looking at those expensive HMDs for a while, and I have to say that this one is a tantalizing alternative!

The more that I've thought about it, the more I've come to realize that the iPhone (or any motion enabled phone) is really the smartest avenue when it come to Virtual Reality, because you have the motion hardware, the rendering hardware, the high resolution display, and wireless connectivity all in one convenient package!

Now, since I'm currently unable(?) to try your FOV2GO, I tested your app (since good hardware is nothing without good software), and I really liked it!
It had very robust tracking; even when I shook it, it always re-calibrated back to normal within seconds. My only gripe was the constant flying forward.

If one were to take his or her FOV2GO to an open space, could the iPhone's accelerometers handle detection of forward motion?
I ask because maybe the accelerometers/GPS could eliminate the need for a "Global" positioning system like Friispace ( http://www.mtbs3d.com/phpBB/viewtopic.php?f=120&t=14069 ).

Good Accelerometer motion, perhaps blended with real GPS readings, could make a system that would be compatible with the redirected walking paper (2nd post in Friispace link). From there, an immersive (albeit uninteractive) holodeck is just a few steps away! (no pun intended)

Pretty good for $5 extra hardware.

@zalo: I have also just recently come to realize that the iPhone (and other phones) are fantastic little sensor packages and is now a direction I am actively pursuing with the FriiSpace project. Inertial units can detect motion but they also quickly accumulate errors and are undependable for tracking position. You have to have an external global position tracker to enforce real world boundaries - otherwise you run a significant risk of bumping into things or worse. Whether you use an optical system or a GPS system depends on the the accuracy that you need.

What, a patent infringement notice sent via an online forum?
How very professional and legal.

This company sounds more and more like some school kids business project, with similar ethics.

I cannot consider engaging in a discussion with you until you come clean and admit that you made multiple fraudulent accounts for the sole purpose of promoting your product. There was no need for this to be a public spat, but that is the only thing that can come from how you are handling things.

I wouldn't even consider listening to anything these kiddies, do unless it was attached to a letter from a reputable legal firm.
Even if they have some sort of patent, I highly doubt it would stand up to any prior art scrutiny.

I lol at the use of CAPS. That just makes it so legit!! ;)

I don't want to drag this out any longer than I have to, but I want to make sure this info is out there for anybody who might deal with this company. ToyIn3D has had plenty of time to respond, and if they dispute any of these claims, I welcome the correction.

1) Your patent application is misleading. The prior art/background section (machine translated from Spanish):
Are known red-blue anaglyph glasses and glasses for three-dimensional images such as "cross-view" or "parallel view" to display stereoscopic content, but so far not implemented these techniques in personal portable devices.
You do not say anything about the numerous commercial devices that have been sold as early as 2006 that are basically the same idea, like the Solid Eye, another extremely low cost 3D viewer:
Image

There are other similar products that you can find if you do a good search for prior use of your idea, like you are supposed to do.

2) The unique thing about your product is that it claims to work with any device. Claims. I don't see any way for that to be possible, as there is no accounting for varying IPD, convergence and focal length, and you claim it works on devices it cannot possibly be used on (Like the iPod Classic), but fine, suppose you have patented the idea of a "universal" viewer? It has nothing to do with other devices like the Hasbro My3D or the FOV2GO, because each viewer is specifically designed to work with a single model of phone. The low cost aspect of your product has been done before years ago, and actually, the Hasbro My3D has been going for less money than your ToyIn3D!

3) I see you took my advice in making an account that clearly discloses who you are, but instead of defending your product, you still seem to want to fight this with your pending patent application. In doing so, you yet again prove that you have been lying about who you are. Making fake reviews is one thing, pretending to be a charitable organization is just horrendous.
Image

Again, I never wanted this to be a public spat, but your actions (And subsequent lack of action) left no other options. Feel free to PM me if you want to communicate further, Mr. Estado/ToyIn3D.

Correct me if I am wrong, in your case, no patent has been granted in the USA yet. In fact the preliminary search during your international patent application has thrown up three similar patents. I think the public can write to the patent office to give important feedback to this specific application. Hint hint.

Hi,

I'm usually just a lurker on this forum - I have an old account but it's linked to an old e-mail address I don't have anymore so I had to set up a new account.

First just to :lol: at the Toy3d guys - seriously surely this can't be patentable, for prior art "The Brewster" from circa 1860:

Image

Looks like it would work pretty well with an iphone etc.. Also more recently theres stuff like the OWL stereoscope viewer (http://www.londonstereo.com/shop_home3.html) which are foldable etc.. etc..

Palmertech - looks great! I'd definitely be interested in one and would happily pay delivery to England. Like everyone else I'd be really interested in a higher FOV version.

I've been playing with a pair of 38mm focal length, 50mm aperture fresnels as as a cheap thin replacement for leap style optics, but I don't have the time, room, tools or skills to mount them properly. There's a bit of fringing in the colours but apart from that, from my half arsed experiments they seem as though they would work great. Really interested to see how you progress with this!

So I've been playing with the app and the 50mm fresnels I mentioned and it works pretty good :) - except for the fact I must look like a lunatic trying to hold to lenses to my face with one hand and keep the iphone in focus with the other while I move around :lol: :lol: - have you thought about putting any stereoscopic settings into future versions of the app/library, it would be great to be able to adjust ipd, convergence etc..?

It's a shame the bluetooth stack is limited on the iphone - I think you have to jailbreak it to use a wiimote? - I guess the android phones don't have that problem? I think the two combined would make a pretty neat setup.

Hi, Palmer. Just dropping by to try and do some damage control in behalf of my fellow countrymen -not that patriotism is a trait of character that I hold in a high regard or anything, but whatever. After what I've witnessed here in the forums I feel compelled to say that I, as a spaniard, am ASHAMED of this people -now, that's a correct use of capitals, BTW- and want to let everybody know that these clowns are not, by any means, any kind of standard by which the people of my land can be measured. Nothing else to add, as yourself and others have already pointed out their childish and immature behavior and, what's worse, deeply low morals. OK, maybe one more thing: their -his? her?- english sucks epic balls. There.

By the way, you can count one more to the list of hopefuls, as I also have an eye put on one of your Oculus -see what I did there? :mrgreen:

Greetings from sunny and -mostly- civilized Spain.

Hey Palmer, I appreciate the Galaxy Note instructions that are up on the ISC website:
http://projects.ict.usc.edu/mxr/diy/fov2go-viewer/

I'll cut them up this week, though I wonder if I can find those magnifying glasses locally (I'll look at the dollar store first). I'll cut one up for my GF's Iphone 4 as well but I'm think she'll think it's too geeky :)

I had a few questions:
I was wondering, earlier in the thread you mentioned working on a wider FOV HMD. Any schematics or plans? I think the resolution is large enough on my note but I was thinking with something like a collimating mirror (similar to what I used to work with in flight simulators) would be OK with the phone brightness and size/resolution, without resorting to a (few) projector(s).

2nd q: Head tracking - I saw you had experimented with your demo game and also the Google Viewer, does the tracking work well or does it tend to drift? Maybe using a filtering algorithm like they have at DIYdrones for the autopilot?

3rd q: any thoughts on pairing the phone with a wiimote or PS3 sixaxis controller for movement? The benefit with a wiimote is that you could put it in a "gun slider" (those plastic accesories they sell for the wii) and read the accelerometer/gyro (if you have the wiimote plus) for aiming. it can be connected with the nunchuck for movement.

4th q: Pupil/eye tracking: the front-facing low-rez camera used on smartphones can be used with OpenCV (http://opencv.alekcac.webfactional.com/downloads.html or http://code.google.com/p/javacv/) to do eye tracking. What do you think of tracking only the left eye and then either move the display or change the focus depending on the part you are "looking at"? Ie: Let's say you have an in-car view. If you look far away in front, the dashboard/steering and left/right will be blurry, but if you are looking at the dash, the outside view would be blurry. http://www.youtube.com/watch?v=HdW1v9TPNYw

How did it go a Maker Faire?

Thanks!

Thanks for the post! Don't worry, I would never think less of a country because of a single person on the internet. If that were the case, I would have to hate my own country quite a bit. ;)

1) No schematics or plans yet, but they will be up as soon as they are finalized somewhat. :)

2) The head tracking works very well, but you should definitely try to upgrade the OS of your Note to 4.0. The Note actually had some of the worst tracking of any Android phone I have used, but the 4.0 update makes it much better. No drift, since it has a magnetometer.

3) This is something we are working on right now. :)

4) We would love to implement eye-tracking, but it is low on the list of priorities right now. A lot of very cool things can be done with it, but doing them right takes a lot of effort. Something else that eye tracking could be used for would be to navigate menus and the like without moving your head, could be pretty sweet. :)

Let me know how building your viewer goes, if you have any trouble getting ahold of appropriate lenses, let me know so I can help you get some.

Android 4.0 puts a device's gyroscopes through a high-pass filter and the magnetometer through a low-pass filter, combining the result into the virtual "orientation" sensor. Previous versions of Android still have the virtual sensor for orientation, but it's just based on the magnetometer, which is noisy. You can get the same results as Android 4.0 (quick, accurate, and stable turns with no drift) on any device that has a gyroscope and magnetometer by grabbing the output from the sensors and fusing them yourself.

Not a new trick, but handy to know. And, as should be obvious, works on non-Android devices as well. :)

I have stopped checking my google reader 5 times a day and now just check these forums 5 times a day. It's the only news I want to hear about anyway. Some exciting stuff! Can't wait for the FOV2GO and the Rift! You should make Rift t-shirts. I'd buy one. I'm an optometrist so I should have some clothing with Oculus on it anyway.

I'm looking at doing some development with FOV2GO as a cheap platform to get experience with HMD and Unity before the Rift dev kit ships. I actually receive my Hasbro My3D recently but would likely build one of the viewers from the FOV2GO project. Beyond the basic iOS/Android games does anyone know about latency for pulling in external data? I would most likely be using an iPhone4...

1) minimum latency for video over local wifi
2) minimum latency for sensor data over local wifi
3) is there a wired approach for bringing in external video and sensor data?

iOS is a horrible platform for this sort of thing. Without paying a lot of money and qualifying as a licensed developer the only way you can easily interface the iPhone is via WiFi. And that interface is not very good for transmitting sensor data. It has a lot of latency issues. See this...
