Durovis Dive 7 for tablets

• removed the original lenses, easy pull out
• added wooden cubes with borehole, left and right, glued with special plastic glue
• used brass threaded rods and brass screws and washers
• some foam styropor
• wooden stripes with boreholes
• some rubber gum to prevent slidings..
• used +5 dioptrien glasses http://www.sehhelfer.de/index.php?searchparam=LUL0486&cl=search&send=Suchen
  magnification x2,25 dioptrien +5.0, ca. 16 Euro
• ZEISS USB head^tracker at right side  (goes to pc, from there via usb serial to arduino to ps4)
• USB OTG + USB Ethernet adaptor from „plugable“ + 5 meters high flexible ethernet cable
• no additional power cord.. but could be done, because sony z3 tablet has an extra power connector

advantages:

• 2D view HMD is possible

disadvantages:

• the weight could be less, own 3D printing
• sometimes fogging from nose breathing, sweating,
• more comfort would be nice

next steps could be:

get rid of PS4 video compression lag
– use display with direct HDMI input..
– or use PC/Laptop with nvidias GTX grafic card for better video encoding and streaming
– or use PC direct USB thethering ( like seen with Trinus VR)

these two eye glasses are better than standard reading glasses for our HMD projects,
they have greater magnification (more then +3.0 dioptrien, mostly the max value of standard reading glasses)

http://www.sehhelfer.de/index.php?searchparam=LUL0489&cl=search&send=Suchen
magnification x2, dioptrien +4.0, ca. 16 Euro

http://www.sehhelfer.de/index.php?searchparam=LUL0486&cl=search&send=Suchen
magnification x2,25 dioptrien +5.0, ca. 16 Euro

usb ethernet adapter from plugable.com (http://plugable.com/products/usb2-e100) works,
we need an additional otg adapter (micro usb to standard usb female) between smartphone and ethernet adapter, ( but there is too, an new ethernet adapter with micro usb available ).
and at least, we need a ethernet app from appstore https://play.google.com/store/apps/details?id=xda.usbhost.test&hl=de

and then we can stream PS4 games like flight sims (war thunder) to android smartphone, tablet (sonyz2/sonyz3tablet-compact) with full HD resolution in 60Hz.. stable.

attention: the tiny lag is still there… compared with hdmi video output on big screen!
but its usable.. so there is a video enconding in ps4 working, we can see some artefacts from video encoding at certain still standing screens.. but not remarkable in game plays.

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

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 !!!
