FullHD to Side-by-Side problems

Veröffentlicht am von
Antworten

when you want to take a FullHD video stream
into Side-by-Side mode for your HeadMountDevice Full-HD mobile device screen,
you will trap into following problems:

1.
keeping landscape mode, alias fit to width, for each eye,
with this mode you will loose in height, image looses its sharpness because of downsampling

2.
fit to height, keeps sharpness, crispy video,
but loosing information in width..
eg any game infos at the original screen corners will disapear,…
we would need to cut out these information and overlay it at the new
video dimensions 960/1080 per eye.. into new corner coordinates..

Dreaming of TrinusVR StreamBox

PS4 HDMI out
PC HDMI out

2D/3D content, FullHD

connect to a MagicBox
that acts like TrinusVR ( http://trinusvr.com/ )..
you can adjust everything to use any headmount display.
The MagicBox captures the input stream and makes halfSBS (or others)
To make all adjustment and settings, you can plugin USB mouse/keyboard and an monitor via HDMI to have screen where you control the settings for output.

The output goes over
– Wifi 2,4/5/60GHz,
– USB using smartphones tethering capabilities
– HDMI

if someone would need to add two displays, to use one for left eye and one for right eye.. then we would need usb and hdmi outputs twice, and some settings more
( 2x samsung S6 with stunning resolution ppi ;o) )

So we could use any smarthphone as head mounted display, with 2D or 3D content.
So far without headtracking.
You need headtracking?  Playing Car or Flight simulators?
No problem, you could use external sensors like ZEISS Cinemizer USB headtracker or even sensors from smartphone itself, if industrie/programmer would support.
Imagine your smartphone send sensor data via wifi to and USB stick which emulates Mouse input… but maybe your smartphone sensors are ugly.. drifting.. so you would need a sensor like ZEISS Cinemizer USB headtracker, maybe even smaller and without cable.

Back to the box.. who could build such a box ?
Maybe proffessionals like team from
https://www.blackmagicdesign.com/de
https://www.blackmagicdesign.com/de/products
https://www.blackmagicdesign.com/de/products/intensity
they have the technology of streaming and capturing, but they would have to add new VR virtual technology like TrinusVR already represents.

 

in case of cabled output using HDMI…
there is a problem today,
were are 5″-7″ fullHD displays with HDMI input?
i have not found them yet..

PC: Trinus VR + War Thunder(PC) + S4mini/Z3tablet

in Android PlayStore i found „TrinusVR“ and so i tested it on my old weak computer.

With TrinusVR you can send Videostream from PC, from a PC window, converted as SBS SideBySide to a Smartphone, with 3D or at least without 3D (Fake3D = 2D).

The App is available as Demo Version „Trinus VR Lite“, was installed easily.

I picked up my old computer, a core2duo 2GHz, and installed
War Thunder. War Thunder looks great even on weak maschines. Till now i only knew the PS4 graphics. And second: PC mouse aiming is not fair. Gaijin should add some option for gamers so that they could decide, if they want play with or without opponents which are using mouse steering.

So ok… start the TrinusVR PC Server. Used first the Wifi setup, USB later. So i took my Z3 tablet and logged in Wifi access point started by TrinusVR „trinus:mypassword“. and then started Android App of TrinusVR. This works, but graphic was ugly.. because PC initial details setup was set „retro“ which means 256 color and block style graphic. While streaming is working we can adjust some settings at PC server software.. Graphic details too, after that it was quite good. But at all my PC was 100% cpu load all time. The main game was running smooth but the stream was not at all. So i guess its a PC CPU bottleneck.

So i went to USB connection. Using USB Tethering on Android. My Z3 tablet is a Wifi only version and it gives me no option for selecting Tethering! So i took my Samsung S4 mini Dual Phone and it has the option Tethering over USB. This works, but better? Maybe the CPU of Phone should be better? And the S4 mini has only qHD, one fourth of HD! while the Z3tablet gives me FullHD.

At the end i went back, using Z3 tablet with Wifi. Using a google cardboard asked me to dig deeper in the settings, because cardboard with its lenses is designed for 4″ Phones and not for 8″ as the Z3tablet is.
But TrinusVR gives us the possibility to adjust everything. Switch to „Advanced Mode“, and „VR settings“ we can arange the SBS view, positioning, sizing, turning.. so i got the cardboard useable at 8″ tablet… not handy but viewable.

but realy playable, it was not.
A better PC-jhardware would be required i guess so far.

Going further… trying Durovis Dive 7 with z3tablet 8″.
or using a better FullHD Smartphone 4-5,7″..
