Manresa Castle: Video ITC
Objective of the Video ITC Feedback Device
When Zak asked us to build a portable video ITC device we wanted to do more than just film black and white static. So we added multiple wireless energy sensors to influence the audio and color video input. During testing of the device we saw numerous images that ranged from disturbing chants on curdled red screens to pleasant imagery like a moving road way to a spectacular sunset.
How the Video ITC system works
The Video ITC system works by focusing a camera on the very same image that it is producing, thus creating an infinity type effect of looking into series of mirrors. The heart of the system is a custom written software program that controls the projector, camera and the offset image inputs for both x,y on the screen. The Vertical and Horizontal sensors were designed as Bluetooth wireless devices allow any changes in the energy fields to influence the images being shown. The controller allowed capture of the video images in real time so no additional gear would be needed. As an optional ITC mode the sensors also had an ability to influence character selection that were shown on screen and spoken by the software.
The device produced anything from pure white screens to multi color vertices:
The horizontal and vertical control sensors make this device so much different than just video feedback of static. With the introduction of a color camera in the system colors made a startling difference when looking at images:
Setup and images from the Video ITC
The images flow like video morphing from the constant feedback and shifts of the image from the vertical and horizontal sensors. The system requires a bit of setup and tuning to get the exact distance from the projections surface between the projector and camera. Lastly audio feedback was added to take advantage of multiple methods of ITC at the same time.
About the Build of the Video ITC Feedback Device
This build took roughly 120 hours between hardware sensor design, software, testing and tuning. The remote sensors are Bluetooth wireless devices sensing energy changes in the form of static ionization or EMF. The bulk of the mounts were built using a laser cutting tool and various 3d printed parts.
