Nintendo 3DS glasses free with eye tracking as an enticement to take up 3D #viewing #futureOf3D
I think the topic "Another formerly popular 3D system discontinued. Why?" was originally about the demise of the 3DS. It morphed into a much lengthier and at times challenging discourse and I think my post got lost in it.
We call for new members to the stereo community and note there are photographers using faux stereo on Instagram and elsewhere who need to be informed of the “true” 3D they are actually creating.
I wrote about how I rediscovered the New 3DS XL and why it has merit as a low cost vehicle for glasses free viewing to entice new 3d recruits and especially the social media wobble photographers and sbs etc to 2 pic glasses free eye tracking easy sweet spot 3d for them and their friends.
As I type this I look down at my New 3DS XL and every time regardless of position there is a 3D view without any effort at all. The Commander tablet to my right requires me to sit at a limited set point to view 3d.
I should point out that I have a number of glasses free tablets, phones and the W3. My view is that none are as easy for the uninitiated to view with an eye tracking camera on the 3DS and the resolution is more than acceptable for this introductory purpose. There will no doubt be those who do not agree.
I have not checked if something similar has been posted before but in any event an easy non technical project may be due for revival anyway.
1. A first time only requirement is
a) enable SBM1 file share in Windows Features in Windows Start.
b) in system settings/data management on your Nintendo use the microSD management feature which effectively sets it up as discoverable on wifi - very easy and I suggest you give it the name Nintendo when asked.
2.Create a folder in Windows and name it to Nintendo's requirements (such as 102NIN02 but also see below for more).
3. Gather your mpo's (200 works fine - 2000 may not) and multi convert with Stereo Photo Maker to 1280x480 - under 80mb mostly and store them in the folder you created.
4. Use a file renamer to rename your files to Nintendo's requirements (such as ADJI0001.MPO to ADJI0020.MPO etc but also see below for more)
5. Open the Nintendo under network in windows explorer
6. In explorer drag the folder you created onto the DCIM folder on the Nintendo card
View your photos using the Nintendo camera choosing slideshow all with random or chronological order. In settings you can set
a) 9 music types or mute background
b) Ken Burns zoom or not
c) 3 or 10 seconds or 1 or 3 minutes or rapid duration for each photograph
d) shutter, dissolve, page turn, wash or random mix for the transition
If all the above resulting slideshow does not impress your non 3d friends nothing will!
Some detail on files and folders
I had 2000 files and 7 folders in a previous attempt with very difficult manual transfer before I realised about the microSD management.
Interestingly I found 2131 pictures in just one folder so I am not sure you need more than one folder.
Here is a list of my folder and file numbers to assist (I am unable to fathom any reason behind the numbering).
102NIN02 through to 107NIN07 (7 in all).
The file naming convention in folder 102NIN02 was
ADJI0001.MPO to ADJI0020.MPO.
ADJP0001.MPO to ADJP0062.MPO.
ADJU0002.MPO to ADJU2050.MPO.
When I took new photos the convention was 100NIN03 for the folder, and HNI_0001 and following for the pics.
My view is that none are as easy for the uninitiated to view with an eye tracking camera on the 3DS and the resolution is more than acceptable for this introductory purpose.
As far as I know, there are two models (plus the XL variants).
The model with eye-tracking is named "New Nintendo 3DS".
It seems that they all have a 400×240 pixels top screen (per eye in 3D mode), which sounds very low definition nowadays but gives surprisingly enjoyable pictures in the old model I have (not as defined as on HD autostereoscopic phone or 3DTV of course)
(I am unable to fathom any reason behind the numbering)
It seems to follow the "design rule for camera file system" of the "Japan electronic industry development association" with a "Digital Camera IMages (DCIM)" folder in the root in which some "100ABCDE" folders (100-999 followed by 5 alphanumeric uppercase letters or underscore) regroup images named "ABCD0001.XXX" (4 alphanumeric uppercase letters or underscore followed by 0001 to 9999 and the extension).
The exact name probably does not matter as long as it follows the rules (a subset given above)

I think the 3d screen is 800x240. But that belies the experience which is much better than the numbers suggest. And I have tried it on reluctant 3d viewers who find the correct point of view difficult and almost an imposition on the the Commander etc but have no difficulty with the 3dsxl and actually spend time looking at the photos.

One more toy to add to my 3D tool kit. So far I have a W3, an Oculus GO and a useless Stereo Viewer (for viewing SBS pics on a monitor). If this device works as described it will be used often.
The main reason I took an interest in the 3DS was that I figured so many people already had one that they surely would want to view 3D pictures on it if they knew how. Let's face it, the 3DS even has a built-in 3D camera. Sounds ideal , right ? But no !
JMH/trivision3d: Personally I bought a second hand Nintendo wide 3Ds for its possibility of augmented reality and for my french "museum" of 3D techniques. There were indeed proprietary photos.
What I found remarkable on the N3Ds for children and for adults with small eye gaps and oculomotors little or not tonic (which can give a background doubled by the transformations of the 3D volume for them very stretched) ... it is the slider that allows to reduce the positive parallax (up to 2D), so each user can have the 3D that suits him. I was surprised that this reduction of positive parallax is done without moving the volume further forward (without floating window).
Almost a pity, it would have been enough to make a fuzzy border retracting the frame, so the window would have been more annoying to violate... and there again Nintendo could have put a second slider to set the negative parallax to zero... it would have allowed a total control and it would have been remarkable.
These settings (at least the one for positive parallax) should be on all 3D diffusion systems... 3DTV, tablet, 3D smartphone, 3D video projector, 3D web viewer, VR headset. Everyone would thus have his own 3D orthostereoscopic 3D and no more infusible duplicate backgrounds. Nobody would see the same 3D volumes.
For the eyes tracking, I got a Toshiba Qosmio 3D laptop ... image jump of one second to recode behind the parallax barrier rather annoying to follow the head and the gamers finally preferred 2D!
