So you want to do some infrared (IR) tracking onstage but there’s too much ambient IR in the space for your blob detection to work reliably? You need to only light up your subject? Or only your backdrop? Never fear. Our bespoke IR emitter solution is here, ready to cancel out your ambient IR. It’s an Arduino plugged into a basic IR emitter from Amazon. With a network shield, the... READ MORE

Our earlier experiments with motion prediction on soft bodies was really just a precursor to a larger goal: Tracking a curtain or sheet as it falls to the ground. We loaded up the software with a camera and projector in our New Jersey shop and dropped a piece of white fabric. You can see the results here: You’ll notice, especially in the slow motion clip, that the top edge of... READ MORE

Every so often, someone asks us about projection mapping a person. Or a dress. Or a dancer. And the answer is usually: “Sure, as long as they only move very, very slowly.” It’s not difficult to calibrate a camera with a projector. A computer looks at the camera, finds the part of the frame that matches the subject, and draws that outline to the projector where it is projected back... READ MORE

On October 24, 2015 The WorldStage Lab brought our new 6.67mm outdoor LED wall to FIGMENT Oakland. FIGMENT is a free public arts festival attracting thousands of visitors to events around the country, and this year’s FIGMENT Oakland marked the second annual local incarnation of the festival. WorldStage’s 18-foot diagonal screen created an interactive canvas, presenting video works in the great outdoors at Mosswood Park! Artists showed camera-controlled interactive video art, audio-reactive... READ MORE

First things first: Figment Oakland is coming up on October 24, and the WorldStage Lab will be providing an 18′ LED video wall for artists and design studios to showcase their interactive video works! Now, we recently learned of a sweet web site: codedoodl.es They provide a Chrome plugin that serves up a fun “code doodle” every time a Chrome user opens a new tab. Lots of these doodles would...

Back to the question: How can we determine where a tennis ball strikes a large surface? What if we use a couple of cameras to triangulate the position of the tennis ball? If necessary, we have cameras that stream as fast as 240fps, and we can monitor a wide region in front of the wall, rather than a narrow plane like we were monitoring with the AirScan. That means the... READ MORE

A question arose recently: How can we determine where a tennis ball strikes a large surface? Well, we have a product in stock from Coolux called the AirScan, which we use sometimes to add touch capabilities to large video surfaces. The AirScan simply spins a laser around in an arc, and at every angle it reports the distance that the laser travels before being interrupted. Here we essentially see the AirScan... READ MORE
