Three-D isn’t as new as many people think. Back in the mid-1800s, 3-D was a big social event using an invention call a stereoscope that David Brewster invented in 1844. A stereoscope was a hand-held device that people looked through. Stereoscopes had photographic images people viewed in three dimensions. Three-D technology now is much more complicated. People either use old-fashioned glasses with two different colors of lenses or newer polarized lenses for viewing 3-D images. Try using 3-D glasses for some cool new uses.
Fun on the Computer
Look up You Tube on the computer, and create an account. You need an account before you set the viewing style of the video to 3-D. This puts the videos you watch in 3-D format. Put on your glasses, and watch the videos.
Create a 3-D Room
Create a 3-D room using different colors of fluorescent paint. Splatter the walls in different colors of fluorescent paint. Use at least 4 different colors, such as blue, green, red and yellow. Put a black light into a lamp or in the overhead light socket and turn it on. Turn off any incandescent or fluorescent light, and put on the 3-D glasses. Look around the room. The paint splatters look like they float around the room. This technique works well in a teenager’s room and people who create professional haunted houses use this technique on their walls.
Check Out the Stores
Go to an electronic store, and check out the 3-D televisions. When you look at the screen, it looks as good as a big movie screen. Look at objects outside and inside while wearing the glasses. Some ordinary objects look like they pop out closer than other objects around you. However, Mark Pesce, a pioneer in virtual reality, warns that children could potentially suffer permanent damage from regular and extensive exposure to 3-D images. Reggie Fils-Aime, president and CEO of Nintendo of America, said he would not recommend that very young children look at 3-D. There has been evidence that extensive 3-D viewing can permanently damage depth perception. The disorder is called binocular dysphoria.
Create Your Own 3-D Movies
If you have two LED projectors, attach the projectors to one DVD player’s output jacks. Place the projectors about 6 foot apart and turn them on. Line up the projectors so the images line up. Look at the screen. You see some strange 3-D effects. Play around with the brightness, turn up the red tint on one projector and the blue tint on the other projector and see what happens.
