Sony HMZ-T1 HMD Owner's dedicated thread - Page 101

Thanks. I've updated my last post to include the word "potential" since you personally describe no problems with vertigo or nausea.

Car [motion] sickness is caused by a very similar, disconcerting conflict of the body orientation senses. When a passenger doesn't watch the road, their visual sense doesn't report that their orientation is being pivoted about and tilted for each turn, bump, and hill. The simple cure is to watch the road, especially the horizon, and then their visual sense will report the same info that their body actually feels, as they tilt, sway, pivot, etc., so there's no conflict.

I think this mainly affects older people, and people who use their eyes to balance and ignore their inner ear. I'm 29 and have no such issues but I've always been active.

This is a health issue not a HMD issue

People rely (partly) on visual information to maintain balance at all ages, even infancy.

yes i am using hmz-t1 for video and sound going through my avr which really feel like i am inside a empty movie theater room.

better make one this year
Hope the HMZ-T1 doesn't end up like the previous Dynaclear screen that stops development.

^Or more appropriately Glasstron which they seem to abandon for years at a time too.

Just got mine a week ago. Seems like the longer you own this thing the better it gets. Contrast is incredible! The 3d is so natural. I also have 3d projectors but my eyes get fatigued using active shutter glasses. I'm thinking the flickering off and on is exhausting to the eyes.

While pixel structure can be noticed occasionally, it is far less noticeable than on my 720p 3d dlp projector. I use a 106" screen and the hmz looks at least that big. Audio I would recommend turning bass and treble to max. May eventually attach different headphones.

Still have slight blurring in corners. However I think this device tends to expose your vision limitations.
I've taken out the gear wheel and painted edges of optics. Removed straps that go around the back of your head. Going with the baseball cap mod with four velcro straps (they velcro onto the hat). Light blockers really help but do dig a little into your face.

This thing requires a ton of modding to get the most out of it but that's half the fun! If you I overlook the few flaws this hmd is pretty amazing.

Hi,
can you please elaborate on this part and why have you done it? what it fixes/solves?

Also whats is baseball cap mod and do you have pics? can you make some pictures and post them?

Many thanks

Now that this has been out for a while I am looking into it again. Right now I have a 70" Sharp and it has shrunk quite a bit. Not wanting to drop the money for a 90" I am thinking about getting one of these for my personal gaming and movie use. How is the 2d performance of this unit? I have never been a fan of 3D and I would rather use the system resources with games for higher framerates and better graphics. For $800 on Amazon this thing is very tempting. (I will probably use it in a reclined position.

You can get it on big shop sellers on ebay for 720$ with warranty and all that, currently there are 2 big electronics sellers with thousands of feedback that have these in almost unlimited quantities..
Both sell for same price so choose the one you like, warranty is from sony anyway


Its OLED, the 2D is great, you wont get any better color reproduction in any screen..

I have Amazon Prime and a Amazon store card so 1 year no interest at least. I don't mind paying extra for Amazon peace of mind.

You can search this thread for both. Briefly removing the gear allows you to adjust each eye independently. The baseball cap mod nothing complicated. Just a simple way to make it more comfortable.

I did a lot of kung-fu, and a great deal of time was allocated to improving your balance by way of intensive training and balance during standing meditation with your eyes closed.

Gymnasts and skaters and skydivers are also some other individuals who improve their balance in this way. But if a normal person over 30 closes their eyes, they will sway around like daisies.

By my guess people who practice martial arts, skaters and gymnasts alike, will have a better, less dissorienting time when using head tracking and virtual reality, or piloting a mobile suit or EVA unit...

WAYYYYYYYY OFF TOPIC.

Today I disconnected the horrible headphones and sat in my hometheater living room. Sitting where I normally sit watching my projector, the audio had a huge effect on how big the image is perceived. I thought I was looking at my 106" screen. If I back my speakers up more, it will probably sound even louder. I wonder what would happen if you sat in a real commercial theater with these on. The image may appear as big as that theater screen. The audio is the only way you can really judge the screen size.

The housing looks pretty cool. Would love to try it out.
Is it up on Shapeways yet?

Thanks,
Kevin

We have begin shipping the light blockers, those who preordered first have been shipped!

We need a good in depth video of how to remove that gear. I been interested in it for a long time. Also has anyone actually taken the HMZ apart, removed the Sony headphones and wired in their own? If so we need a video of that also. I am dying to rewire some better headphones.

Its interesting that you can take the hmz completely apart with just a couple of small Phillips head screwdrivers. It is like it was designed to mod. The headphone wires are so tiny. I read that a good way to get the plastic off the wire is to melt it off. I will be doing that soon.

I know many Sony headphones use "litz wire" which is not very agreeable to either melting off the insulation without damage, nor soldering in at any old place you choose (like where you cut them). If there are visible solder points for the molex connector on the transducers or the circuit board, THAT's where you should be modding to, rather than cutting the wire itself and "stripping the ends". [If it is indeed Litz]

I think you are right about the wires. They look like no wires I've seen before. I do know where the connector is to the board though so I'll try that route. Thanks for the heads up.

Here's an update on how to convert the AC-->DC transformer to DC-->DC converter. You can use any input from 9v to 30v DC supply to run the unit. Using Energizer XP18000, I can run both media player and HMZ-T1 as a mobile cinema setup. The voltage is 5.62v using variable DC to DC converter that can output at 3A (meeting the requirement of 15w).

Woah, rjyap... So you made it portable:D Cool, how long will the battery last running both? The thing is, though you can run the HMZ and the pass through reciever how can you also run a 3D BD player?! A 3D BD player is also large so would be kinda pointless. You could use a latop but that's also still big.

Sadly the Sony HMZ is just to bulky to make portable and carry around. The ST1080 was very light and portable but it's horrible image and numerous problems make it worthless to even bother.

Haha, cyborg... That would be interesting walking around town like that.

Are the Cinemizer OLED HMD's out yet? I wonder how they compare to the Sony HMZ... Found a few German videos but no clue what they are saying, and can't find any place to buy them.

Despite earlier claims that they would be HD, it turns out the production version is actually SD. Still interested in it? Not me.

That sucks... Could have had a good product if it was in HD. I just read about that... If it was much cheaper for a portable device it may be interesting.. But for a price of $800 they can kiss my butt.

I'm pretty sure the optics in the hmz are made of glass. Would making them plastic reduce image quality a lot? It would certainly be lighter. Pretty sure the optics are the heaviest part.

This kind of reminds of me crt projectors where you need to have everything perfect to get a sharp image, yet still have blurry corners anyway.

Watched Hubble in 3d. The dark space scenes were breathtaking! I thought my RS40 did that well. Hmz destroyed it. It will be many years before a projector will have this kind of picture quality. And for those without a batcave, they may never experience this.

The optics are small and any weight difference between glass and plastic would be inconsequential. [Not that I'm confirming they are glass, BTW.]

I concur that the optics is glass and it's quite thick. I can feel the weight of the optics when stripping down unit. The only problem changing the lens is the focal point and magnification parameters for the current lens.

For portability, I can run a HDD based media player (For 3D, check out Himedia HD900A) and HMD simultaneously without going through the receiver. You can even put this in the car and enjoy your in car entertainment. As for runtime, I estimate around 3 hours running on battery.
