In the 90's era, there is a toy that looks like a pair of
binoculars and can display images from a paper plate. And now there is an
additional accessory for the iPhone 4/4S users, which shape almost the same to
the toy, and known as the Sanwa Stereoscopic YouTube viewer.
In addition similar to the View-Master 3D is already
antique, this device also has a similar function, but using the iPhone as a
media for displaying images. How to use it, there is a slot to plug in your iPhone
4/4S horizontally, and with the small viewing distance, 3D movies will appear
much larger than the iPhone’s
Interestingly, This device is specifically used to view
stereoscopic YouTube 3D movies or video yt3D with a wider view, so the
experience Stereoscopic 3D movies will be more fun than using the red-blue
paper glasses. Unfortunately
it’s only for Japanese iPhone users at the moment and retails for
1,980 yen (approx. US$25), hopefully in the future these devices will be available for global
markets.
