My group created the shadow image rendering installation or SIRI. Using the installation, the audience was able to create colorful images on the computer. The computer detected shadows and drew the shadows it saw in various colors.
I had the idea of an installation in which the audience was the actors and the outcome of the installation was a sort of drawing. As a team we all took our ideas and blended them together with this vision as the center. I should point out that though I had this idea in my mind when discussing project ideas, others in my group had the same idea at the time.
I was in charge of visual input. I envisioned and made the physical aspect of our project a reality.
I had to figure out a way for people to be able to draw using either their hand, without their entire body appearing on the screen, or their entire body . I decided to make a frame with a sheet stretched across it. The idea was, that the camera would detect shadows cast onto the sheet and use those to create the drawings. In the end, I, with help, created an eight-foot by eight-foot wooden frame that held a screen made of white paper.
My original thought was to have 2 high angle sidelights and one light pointing straight down from the top of the frame. However this would make the shadows much longer than the object casting them. Instead of only having high lighting, I decided that low lights were needed. In the end we attacked arms to the wooden frame and hung two high and two low lights. Here is a diagram of how the frame with the lights and their angles.
In addition I worked with Csound in an attempt to see if sound could be interpreted into the installation. In the end, we decided against incorporating sound into our project.
