Stereoscopic display art installation

stereoscopic-display

This rig is something of a museum or art installation, but the concept is so simple we thought it could easily inspire your next project. The two mirrors and two video sources make up a stereoscopic display.

The user sits between two displays (computer monitors shown here, but the post also shows images projected on two walls of a room). A pair of mirrors mounted at forty-five degrees form the eye pieces. It’s a V-shaped mirror assembly in which the narrow end pointing toward the bridge of the user’s nose. The mirrors reflect the images from the monitors, giving a different view for each eye.

In this case each monitor is playing back a video loop, but one is just slightly longer than the other. Each monitor has a potentiometer in front of it. The user can turn them to speed or slow the playback in an attempt to bring the video back into sync. We don’t think we’d replicate that portion of the project. But it might be fun to view some stereoscopic clips in this way. There’s even instructions on how two cameras were used to record the scenes.

You can get a closer view of the test apparatus in the clip after the jump.

    There’s a trick you can do with sunglasses. Load up a youtube video shot out of a car window etc. where the scenery is moving sideways. Then put the sunglasses on front of one eye only.

    The lowered light input to the eye makes it react more slowly to the picture, which combines with the parallax effect in the picture to give both eyes a view from a slightly different angle and the scenery should pop out in 3D.

    I’ve seen a similar rig at an SPIE conference a few years back, this is the original Wheatstone(yeah the same guy who came up with the bridge) configuration of the stereo viewer.

    It’s a simple and effective means of 3d fusion and a lot more feasable with cheap lcd displays

    You could probably recreate this with a couple of smartphones and some programming.

    The picture reminded me of that cartoon villain who used bees to attack his targets…
    he kept saying “swarm”, “Swarm!” It might’ve been on Space Ghost.

    Really inspirational, thanks for sharing! I just cannot wait to give it a try, I think I want to figure out to visualize my generative architectural spaces this way. It would be terrific!
