Breaking Through Optical Feedback

The problem with projecting costumes, fashion or other augmentation on a person's body is that whatever you project tends to mess up the camera tracking.

A good example is a white dress: What if you wanted the dress to be red. You'd program your optics to identify the white dress. Once found, activate a projector and precisely hit the location of the dress with red light. Easy right? Yes. The difficult part is what happens next. You must now track a red dress. One that is being made red by a projector. The algorithm should still look for white dresses, because the target is still a white dress but also red now, you have to keep projecting the red light to keep the dress red. So what if there is another red dress in the room? Do you color it extra red with the projector just in case it's the augmented white dress? You can see that quite quickly, the subject of live simultaneous projection and tracking becomes complex computer science.

Though I have nothing I can publish (yet), I'm pleased to have made enough progress on my own solution to the projection/tracking issue to warrant a video.

I successfully interacted with projected lightnuclei without causing interference in the optical flow controller. This is a big deal because it opens the door for me to create immersive digital environments that are sensitive yet stable and don't get lost in image feedback loops, flicker, freeze or go "anomalous".

I solved the issue with something I hacked together that I'm calling a Recursive Light Engine (RLE). RLE detects optical feedback and can adjust the variables which influence the feedback loop, though RLE doesn't avoid optical feedback, there's no way to tell it how the variables must shift since each feedback condition is unique. The RLE is basically a harness and a floating scale velocity modulator.

How do I modulate the velocity of light in optical feedback conditions? if you want to join the group as an investor, I'll let you know how i did it. It's wicked.
