Counting Down

Filed under: Interactive Multimedia Art — Mia @ 6:54 pm

Three days from now, our class gallery exhibition begins. This is the preliminary set-up as I work on the book that will be placed on the music stand. The orchestra light is the support for the webcam, and the installation workstation will be covered by a sheer curtain that diffuses the lamp light and is blown by the fan.

Stepping into a Story

Filed under: Interactive Multimedia Art — Mia @ 12:47 am

I’ve had the idea for an art installation project since my 3-D Design class in 2009. I didn’t have the skills to bring the idea to fruition—until today! In Interactive Multimedia Art, David Fodel taught me how to use a relay switch, PowerSwitch Tail II, to turn a fan on and off from Max/MSP software. That may seem insignificant to some, but for me, it’s the last element of a project-come-true.

The idea, from two years ago, was that a viewer would turn the pages of an interactive handmade book, and the personal story, with digital watercolor illustrations, would come to life. The turn of a page would create an interactive experience with video, audio, light, water fountain, fan, and planetarium turning on or off, according to the page of the book. I recently found a video of a similar ImaginArt project that might give a better idea of what I’m planning.

Earlier this semester, I connected fiducial markers through ReacTIVision and a TUIO client to a Max patch. A webcam can view a specific symbol on the page of a book and relay a related value to Max. That value is sent through the programmed Max patch to an Arduino, a circuit board that connects to the switch. The Arduino is coded to understand when to turn the relay switches on and off so the planetarium, water fountain, and fan turn on in time to synchronize with video and audio—for the interactive experience of the beach beneath the stars. The December installation of our class final projects is scheduled for the Object + Thought Gallery at 1430 Delgany Street in Denver.

The “Build the Project” section of the flowchart is nearly finished. I’ve purchased watercolor paper for the Epson 4800 printer and need to create the story’s illustrations next. Hopefully, there will be installation photos in December!

Max iTable and Midi Interface

Filed under: Interactive Multimedia Art — Mia @ 1:40 pm

In Interactive Multimedia Art, we’re completing our Max tutorial and moving into using MSP objects. One of the Max tutorial exercises was to create an iTable that I chose to integrate into a midi interface. The images are screenshots of the user interface presentation mode and a closer behind-the-scenes look at my iTable Note Reader. The lines one draws on the iTable are converted to the keyboard notes and shown in the scroller as they play. Each note changes the color of the screen and there are presets with various voices.

Max Vizzie Modules

Filed under: Interactive Multimedia Art — Mia @ 3:46 pm

We just completed the second week of Interactive Multimedia Art and, already, our projects are exciting. In the software program, Max MSP, we used Vizzie modules to create a video mixer. The “FOLLOWR” module sends data from an audio file to affect a video “XFADR,” so the final output pulses with the music. The audio track is from a previous Color Theory assignment and contains the song, “Autumn,” by Per-Olev Kindren.

The critique presentation was projected while I used the computer control panel to adjust the projected video. Since then, I have added loading objects to preload videos and set sliders with saved presets, for a more automated video mixer. The YouTube video is a behind-the-scenes Camtasia screen capture of the mixer control panel.

Signature in Lights

Filed under: Interactive Multimedia Art — Mia @ 2:14 am

In fall semester’s Interactive Multimedia Art class, we’re learning the basics of programming with Max MSP software. Signature in Lights is a series of colored buttons and delay objects, with their associated patch cords. As you can see, keeping track of input and output connections can be a challenge. In the case of setting three hex colors for each of a hundred buttons, the process takes some patience, too.
