POV Hologram Display

Inspiration

What it does

We are building an Arduino UNO based holographic display. The holographic display works based on persistence of vision, which simply means that if things are moving faster than the eye can process, the previous image remains in the retina. We achieve this using rapidly moving LED's mounted on top of a DC motor that spins very fast. If we accurately time the flickering of the LED's, we achieve an effect that allows us to appear to holographically display text and other graphics in the air. Our primary sensors will be one vision/motion sensor. This will either be in the form of a camera, PIR, or ultrasonic sensor. Essentially, we aim to translate motion into changing some element of our Holographic display (where a flicking hand motion could indicate changing the text displayed, or moving close to the ultrasonic sensor could indicate changing the colors of the display). Additionally we aim to use a second bluetooth sensor on the arduino to change the text displayed remotely from the computer.
