2D HMD – testing reading glasses +2,5 dioptrien

to avoid cross eyed viewing a smartphone infront of my face i tested reading glass.

i used cheap 10 euro reading glass with head mounted smartphone(sony z2)/tablet(sony z3 compact)
This works very nice, better than cheap fressnel lenses.
Reading glass gives very brilliant image and is very comfortable to wear.

+2,5 dioptrien is usable, but +3,0 or more dioptrien would be great, because
the distance of the smartphone/tablet is still more far away then the x4 lenses of google cardboards.
You can buy +3,0 dioptrien easily, but more dioptrien..

17,00 euro
http://www.sehhelfer.de/index.php?cl=alist&searchparam=&cnid=42f48c815c0948b12.20857754&attrib[Dioptrien][]=4,0

i took a second identical reading glass and removed parts of the frame.. so i could use it
as second glass directly on the first glass.. this works.. but there is a 2-3 mm air between the glasses… the impression is not as good with single one, so further test could be
to buy reading glass lesnes without frame and use them directly on first glass.

so the best solution would be a single glass with high + dioptrien..

http://komerci.de/informationsservice/dioptrien.php dioptrien vs. magnification factor
google cardboard has 4x magnification factor.. this means a dioptrien number of +16 !!!
our reading glasses with 3 dioptrien have only magnification factor of 1.75 !!!

2D FullHD HMD – magnifying lens

using a magnifying lens, type fresnel, like this one:
http://www.rakuten.de/produkt/moses-verlag-gmbh-librix-folienlupe-945796086.html?_ga=1.29934527.1041642812.1451245370
costs only 5,- euro.

we can use a tablet like Sony Z3 tablet compact or smartphone like Sony Z2
(with native Playstation Remote Play + Fligh Simulation (WarTHunder) + Headtracker),
bring the display very close to our face while using the magnifying lens to avoid crossing eyes,
having 2D full HD working, in none Side-By-Side.

so we can try to build something from scratch or modify a durovis dive 5 or durovis dive 7.
so we can have today, what cmoar wants to bring out anytime in a commercial version, the 2D mono lense.

this will be a good base for PC based game streaming too.

the ways to 2D full HD HMD

Headtracking via ZEISS USB headtracker.

we have to think about
– single display(like Occulus, SonyVR, SideBySide, one display for two eyes, for each eye a square display fieldview) and
– dual display setups(like StarVR.com, one display per eye, with square or landscape display fieldview)
– single and dual display solution with flat views or lense corrected views, this problem have both solutions

2016/TODAY half-fullHD, 2016 fullHD possible(2D,next 3D too), NEXT years: 2k, 4k:
– 4k smartphone display will appear from 2016 (Sharp 4k displays), but not cheap, intermediate price, not with display port/hdmi input
– 4k graphic cards, PC systems will take time, not be cheap, intermediate price..
so there is a place for fullHD solutions.

Next needed Graphic card hardware option, needed from Geforce, AMD,
is the
– two display-ports/two hdmi-ports solution, one output port for one display, so we could setup two display VR 2D/3D solutions directly without the need of additional hardware
today graphic cards with two identical/different outputs are available,
showing same view to all displays is possible, but connectors/connections to displays is difficult.
thinner or flexible good qualitity cables needed

PC FullHD -> HDMI splitter 1to2 -> 2 FullHD 6″ displays
same setup could work with 2k and 4k.. if PC an splitter can support this
or
PC FullHD -> 1 FullHD 6″ display with CMOAR Monolense, if CMOAR will ever deliver this item,
or cooperation with waerility (kickstarter.com/projects/wearality/wearality-sky-limitless-vr)

PC with TRINUS VR can only support one client, so actualy we can not
connect pc to an usb hub, and connect two 6″ displays to the hub,
using usb thethered mode
maybe TRINUS VR will get an update for such dual screen setups, with one single view per eye/per display, and no SideBySide.
http://oddsheepgames.com/?forum=developers

using two FullHD smartphones for 2D dual display HMD, we would face the needing for turn one smartphone, to touch the smartphones with the thinnest frame part (top) to each other.
Maybe manually locking the screen turning can in correct position can already solve this.

China topfoison.com delivers 1080p and 1440p display inclusive HDMI input connector board.
So we can/could (not tested yet) connect PC/console directly to the fullHD display.
We could use dual display setup with HDMI splitter, or single..
without wifi lags and quality issues.

AVERmedia Encoder SE510,
avermedia.com/professional/product/se510/overview
with HDMI in and Wifi 2,4/5 GHz out and Ethernet out, and HDMI passthrough
using this device we could setup an dual display (smartphone) version.

smartphone inputs:
– usb thethered (best)
– wifi 2,4/5 GHz (second, alternative, using apps like splashtop,…)
– usb ethernet adapter (best, smartphone dependent)
– smartphone weight is higher then bare display

bare 6″ fullHD displays:
– MIPI
– DisplayPort (Retina Displays)
– HDMI (rare buyable,.. )
– looking for display controller boards
– bare display have lower weight

China VIVIGA VR
290,- euros for a fullHD smartphone(android4.4) solutions with addtional HDMI input!, and sensors, buttons,.. using this as base of single and two display solution seems possible..

FullHD to Side-by-Side problems

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..

PS4 + PS2 steering wheel logitech GT force feedback

PS4 game: „project cars“ http://www.projectcarsgame.com/
the steering wheel from PS4, the logitech GT force feedback,
does not work with PS4, natively..BUT

„Cronus Max plus“-device from http://cronusmax.com/
is the solution, to get „every“ input device working with PS4.

to order in germany use:
http://www.controller-tuning.de/Cronus/

its your own decision, to use your existing wheel further, or buy a new PS4 compatible racing/steering wheel

at first i did not got it to run.. so its not plug and play..
but with several resources from internet, cronus forum and youtube vids, and a bit of luck
i got it running..

i used a laptop (core2 duo 1,8GHz, 3GB, SSD, windows 10 (32-bit)),
install driver for the logitech racing wheel,
http://support.logitech.com/product/driving-force-gt#download
this driver package works for the old PS2 GT wheel too!
install and calibrate the racing wheel…
take a sheet of paper, paint the wheel with all its buttons, and name the buttons.
now we need a usb hub,
connect to usb hub to pc,
connect the racing wheel to the hub,
connect cronus max plus with its sideway mini usb to the usb hub,
do not connect anything at the end of cronus max plus.. leave it free,
connect the cronus max plus adapter with ps4
download and start the cronus max (http://cronusmax.com/cronuspro/),
start the cronus software,
tools -> cronus update (v1.0, 2015-02-15)
tools -> firmware update
plugins -> plugin manager -> X-AIM Plugin, install
tools -> Options -> Device -> output protocoll:PS4, Configurations:Slot Recall selected,
start the X-AIM plugin using plugins -> X-AIM

choose the ps4 controller
save new profile, name it as you want, choose your aplce to save it,
we will use direct input method,
the GT racing wheel nether occured as input device(left screen) in the device panel, but after mapping the device panel rightside screen displays our button pushes,
DI enable – works only when you have selected the GT wheel in the menu „xxxx“
device panel, push buttons of your steering wheel and see which Var is displayed… and note this on your paper sketch now… do this for all buttons, wheel, pedals..
these Vars we need to map to the ps4 controller now..
right click the white squares and select DI input, select from list the correspondent Var,
when you have all wheel buttons/wheel/pedals mapped save your profile!

a tip: you can map additional keys, i mapped additional inout, mouse input left click to the PS4 controller X-Button, this is usefull in PS4 menu.. do this later if you recognize an advantage og this tip

there is a tiny bug..
sometimes steering left/right, the PS4 ingame wheel is stuttering… and button pushes are reflected as the button pushes where done rapidly serveral times in one row..
then i have to close the PC software of cronusmax and open again..
then it works fluid..

i use it without force feeback.. if this it possible to map, i dont know, there options in the game and in the cronus max software

finaly it works ;o)

PS:
cronusmax does many things more.. use additional keyboard to place insane combos to a single keyboard-keystroke, or playing ego shooters with mouse and keyboard,.. and others more

next steps.. get head mount device like cmoar/auravisor or PS4-VR

SONY Z2 + Android native SBS + PS4 Remote – finaly DONE

this will give you a 2D HeadMountDisplay, not 3D!

SONY Z2 smartphone rooted with Cyanogenmod CM11

sdcard needed, is mounted as /storage/sdcard1/

Attention:
getting your bootloader unlock code from SONY
http://developer.sonymobile.com/unlockbootloader/
you need a email adress with a .com adress!
with gmx.de, gmx.net, web.de adresses you will get no answer, no key from sony service

i used the way using a sdcard,
copy the zip on sdcard and so on…

the drivers you will need:
http://doomlord.xperia-files.com/download.php?dlid=Rmxhc2h0b29sLWRyaXZlcnMtMS41LTIwMTQwMzE4
Flashtool-drivers-1.5-20140318.exe
after installing the drivers fastboot will respond correctly
fastboot getvar version
version: 0.5
finished. total time: -0.000s
so then you can unlock bootloader

to have Googles Store we need GoogleApp Set
https://wiki.cyanogenmod.org/w/Google_Apps
we have with CM11 the android version 4.4.4
it the Z2 processor a 64bit version?
http://www.gsmarena.com/sony_xperia_z2-6144.php
Chipset Qualcomm MSM8974AB Snapdragon 801
CPU Quad-core 2.3 GHz Krait 400
http://www.notebookcheck.com/Qualcomm-Snapdragon-801-MSM8974AB-SoC.103629.0.html
64 Bit 64 Bit wird NICHT unterstützt
-> ARM.. kein ARM64, kein x86

i took the stock Google_Apps version..

the rest is described yet in the manuals..

then added App Android native SBS.. cost some bugs…
giving root to this app if asked for
ImageDistance 0 and Zoom 100% will work.
my hint: use a bluetooth keyboard with additional touchpad to navigate in SBS mode.. will be very helpfull.

Then PS4 RemotePlay app
latest version 1.3.2

allow apps from unknown sources
http://www.mediafire.com/download/s2l9dl5el2d42lr/RemotePlayPortITBV1.3.2.apk 5.88MB
RemotePlayPortITBV1.3.2.apk
copy to sd card.. from pc over usb cable to the phone sd card
filemanager, install apk file..

i have a bluetooth keyboard+touchpad for SONZ Z2 SBS-Mode,
PS4 has keyboard, mouse, DS4 controller,..
i did not used the App Sixaxis

CM11 was not working over ethernet, so i tested App Ethernet.. but PS4 remote play only worked with Wifi..

RemotePlay App Settings Quality and RefreshRate from Standard set to High.
PS4 connected with ethernet to router. Router has wifi net, which the SONY Z2 is connected to.

Using a Homido headset.
Nice result.. but WarThunder is playable, but not against other players.. its good, but not good enough.. WHY?

SONY Z2 has a FullHD display..
and we use SideBySide SBS.
So two screens are displayed in a single FullHD display.
This results in a QUARTER HD final resolution!!!
Playing WarThunder we will need finaly FullHD (per eye when SBS method is used), this means 4x FullHD resolution, so that each eye gets its own FullHD view.

!!!
– WE NEED 4K Smartphone Display or
– or The Games must render crisp screens in Quarter-HD that result in crisp view
– or CMOAR Headset 2D mono lense will give us BEST Result in FullHD
!!!

All the VR sets coming soon
http://www.vrnerds.de/hardvr/96-2/vr-brillen-vergleich/
are FullHD for both eyes..

I give my attention to CMOAR Headset 2D mono lense.
http://cmoar.com/lp_2d.html

then we can go again with SONY Z2 and PS4 RemotePlay, without SBS, in finaly FullHD.

Saitek X55 – Verlängerung – DIY

X55 Joystick besitzt bereits 16-Bit-Querruders und 16-Bit-Höhenruder,
eine Verlängerung würde die Eingabe vom User nochmals präziserieren,
und wäre einem echten WW2 oder Kunstflieger näher als ein kurzer PC Tisch Joystick.

Der joystick läßt sich von der Baseplate durch einen Schraubring einfach entfernen.
Nun muesste man eine passende Verlängerung dazwischen schrauben,
natürlich mit Verlängerung der elektrischen Verbindungen.

sollte man heute einen Adapter herstellen können, bei all dem 3D Printer Hype.

Aber wo sind die passenden 3D Scanning + Printing Services ?

Oder man vermisst das Gewinde, und hofft, dass es Standardmaße sind ( amerikanische inch-Maße? )
und versucht die Gewindeteile im Baumarkt/online zu bekommen.
