Viewing Old Stereograms with My Hasbro MY3D Viewer

It just gets better!

I was thinking that I might have to get some “converter” app so that I could view old stereograms on my phone using my MY3D viewer, but  I didn’t have to do anything to the scanned images.  I just opened the image on my phone, placed the phone in the MY3D, and it works great.

Here is another photo (not a stereogram) of the same room and you can make out distinctive items from both images.

It is amazing how the mind works.  The items in the images appear “flat” but they have a sense of depth which does provide added life to the photos.  Amazing that images taken more than a 100 years ago appear so remarkable.  There are some amazing images taken from the Spanish-American War 1898 at the above Boston Flickr site.

google-cardboard-glassesWhereas the Hasbro MY3D Viewer works perfectly well with displaying stereographs (and it is easy to use your finger to move between slides from the holes on the bottom of the viewer), this Google Cardboard viewer does not display the stereoscopic images well.  A large portion of the displayed image is distorted.  There is also no easy way to move from one image to the other.

Cardboard Camera Turned Inwards?

Okay, I don’t know that this would work with the Google Cardboard Camera software, but it would be worth a try…

Could you use this same software to capture a 360 degrees view of an object (e.g. cup, doll, statue, etc.)?  Place the camera at the outside of a Lazy Susan facing inwards.  Then place a stationary object in the middle of the Lazy Susan, and start the image capture, rotating the Lazy Susan and camera around the object 360 degrees.  *The software is already aware of the camera rotating 360 degrees, facing outwards.  Shouldn’t it be just as aware if the camera was facing inwards?  After all 360 degrees is 360 degrees.

I think the logic works.  Now we just have to find if it works in the real world;-)

Hasbro MY3D Viewer

IMG_0750 IMG_0748 - Copy IMG_0747 (002) - Copy IMG_0745 (002) - CopyI bought a cardboard version of the Google Cardboard viewer.  The lenses were not well ground, so there were imperfections in viewing images.  The other thing was the sharp edge of the cardboard cut into my nose.  I happened to see this Hasbro MY3D Viewer on sale and thought I might be able to make it work for my Samsung Galaxy SIII smartphone.  *One of my “good moves”.

At first I had to physically hold my phone against the back of the viewer, but MY3DVELCROHOLDER2the lenses were good and produced a pleasing 3D image.  It wasn’t too long before I saw that someone on eBay was selling this viewer with a modification.  They had used a crossed pattern of two strips (I thought they might be velcro on the ends.) attached to the viewer.  You could detach the strips to slip in your phone and then snuggly reattach the strip to the viewer.

I happened to have some Scotch Multi-Purpose Fasteners that I had bought some time ago for other purposes.  The Fastener system had matching velcro strips and the back of the velcro had a strong adhesive.  I cut a couple of short strips for the top & bottom of the MY3D viewer and attached them with the adhesive backing.  I then put my phone on the back of the viewer and measured out a velcro strip to attach to the top & bottom of the viewer while holding the phone snuggly.  It worked perfectly!  I didn’t even need to add the horizontal cross-strip.  *Sorry, for not showing the phone being held by the velcro strip, but I had to take the pictures with the phone;-)

Google Cardboard & Cardboard Camera

I tried out the Google Cardboard app, without the glasses, on my Samsung Galaxy SIII (Android) phone.

Addendum [09/22/16]:  Just found this.

I then installed the Google Cardboard Camera app and created a view of our Cook Training Lab.  I tried unsuccessfully to create the 3D image just holding the phone and moving around slowly, but it failed twice.  I then brought out the old camera tripod and walked it around and made the image below.  Pulling this into the Google Cardboard app displays a 360 degrees view of the lab.  *I didn’t record any narration, but the app allows for this.  IMG_20160119_093937.vrI’ve also just ordered a pair of Google Cardboard glasses from Amazon.com which should be here by Friday.

The Google Cardboard glasses arrived.  Pretty much of a disappointment.  The piece that Screenshot_2016-02-17-09-20-39fits over the nose cuts into the skin uncomfortably.  The image did not display well on the large lenses.  I fiddled a few minutes with it and have since left it alone.

ADDENDUM [02/17/16]:  Got back to this last night.  I am using a Samsung Galaxy S III Android phone.  During Cardboard app setup you are asked to scan a QR code from the glasses and that will determine the viewer type.  Apparently, there is a problem (with some S IIIs) that cause the image displayed on the phone to be small and at the bottom.

mbcr9kfSomeone had modified some of these settings and provided a QR image to switch to the alternate viewer with these mods.  This moved the image to the center (bottom-cenScreenshot_2016-02-17-09-17-29ter-top) and made some other mods I am not quite sure of, yet.  But, these changes made the viewer usable.  The clarity of the projected image isn’t great, but it is close to a poor Vue-Master rendering.  *I am thinking that a 3D printer and some creativity could take these viewers in a differentqalbw9ysyp0bl8k9fbyz direction.2-17-2016 9-58-06 AM

You could go here, Google Cardboard Viewer Profile Generator , and play with some of the settings to see if you can make a better viewer.

If anyone else is still stuck with a Galaxy S3 (like me) and Google Cardboard displays way too small to be functional, I finally found out how to get it to work properly.

How about putting play dough over the nose piece to make it more comfortable?  How about using a 3D printer to create a nose guard that can be attached to the Cardboard Goggles?

 

IMG_20160216_134529.vrA comment on the above VR image:  I am surprised that my image is not blurry.  How did it take into account that my slightly moving arms & head, and blinking eyes should not be included in the final image?

 

Above is the phone on the camera tripod.

Intel Boxed Compute Stick with Windows 10 Pre-Loaded

They just keep getting smaller and smaller.  Amazon.com currently lists this for about $134 +tax, but I saw something on TV just yesterday regarding when electronics “deals” are best during the holidays season.  The Monday before Thanksgiving is supposed to be the best for these types of items.

  • New Generation compute on device that transforms any HDMI display into a fully functional computer
  • A solution with plenty of storage and performance needed for light productivity, social networking, web browsing, and streaming media, such as Netflix, Hulu, or games.
  • Enable thin-client solutions for small- to medium-sized businesses, delivering ultra portability and reliable plug-and-play simplicity, with Windows Remote Desktop access for on-the-fly support
  • Windows 10 Pre Loaded (includes PowerShell)

It has a USB port, Wi-Fi and Bluetooth 4.0 support and a mini-USB connector for power, Pre-installed 32-bit OS: Windows 10 and micro SD card slot for additional storage

NOTE:  I asked about PowerShell being included with this Windows 10 because I recently have been learning some PowerShell scripting so that I could modify and use a “content migration” script via the Canvas LMS API.  *Versions of Python (v 2.x & 3.x) are included with the Rasberry Pi that I have.  I also have one of the Logitech wireless keyboards (shown below) that I use with the Raspberry Pi.  It is slightly smaller than a full-sized keyboard… and I think it is the location of the “Shift” key that causes some problems when I am using Python.

I have a Chromecast that is hooked up to my 40″ HDTV so I know how nice it is to push web video/audio to the larger screen.

Video Teleprompter Lite by Joe Allen

A couple of years ago I had come across a video recording teleprompter (VRT2) app that worked pretty well on my iPad.  But, after a short time, the company disappeared, and I did not see the product reappear.  As I recall, the product had some glitches, but nothing that couldn’t have been worked out with time & effort.  The one thing I do recall is that the text was displayed across the entire screen (with the video that was being recorded in the background), and this meant that it was obvious you were reading from a script (by following your eye movement).

A short time ago someone asked if I had seen the Video Teleprompter from Joe Allen.  I didn’t have the time, at the time, to go look at it, but took a look at it this morning.

You might think that having the text scrolling window so narrow would be a negative, but there is method to the madness.  Focusing your eyes on the brown highlighted area on the left of the screen to read your text puts the focus of your eyes close to the camera lens… so you do look like you are speaking to the camera, and not just reading.

Here is a brief example of a video recording I did earlier this morning.

Okay, so I have my bifocals on, and you note the tilt of my head backwards in order to read the text clearly.  Still, it is pretty close to “talking to the camera.”

Raspberry Pi, Ubuntu & Python

Raspberry-Pi-LogoI am not planning on writing in detail here, but just adding a reminder of how well these tools work together when you are wanting to learn Python.

 There are currently two versions of Python (2.x and 3.x) and eventually 2.x is going away (supposedly), but those that have created their

programs in 2.x probably don’t want to put in the time to recreate their apps in version 3.x.

I don’t recall which OS version I used for my Pi, but it was one of the standards that I burned to a Micro SD card.  This OS has the two versions of Python already installed, so I can work through the Python programming basics using my Raspberry Pi.python-logo-large

I also have Ubuntu 14.x on an old laptop at my office.  This has Python 2.x on it, so I can work on learning Python at the office also.

Dr. Charles “Chuck” Severance currently is offering a free Python for Informatics: Exploring Information book & online materials to help you learn Python at PythonLearn.
