Interactive Tech Demonstrations for Live Performance
Historical note Analog vs Digital
Starting back in 1965 I think Variations V is a prelude for things to come:
Cage, Cunningham, Van Der Beek (& Moog and Tudor): Variations V

HARDWARE: Depth Sensing Cameras
Xbox Kinect and similar depth sensing cameras are at the root of a lot of gesture and movement controlled art works/performances.
Rashaad Newsome is using a Kinect for the Five SFMOMA piece, I will demonstrate how that piece works.
Below are a few basic examples so you begin to see the correlation between body and camera, some samples are long so feel free to scrub around these video examples.
SOFTWARE: Max MSP
I teach the software Max MSP from cycling ’74 so most of these examples are rooted in the use of that software.
Demonstration:Computer Vision with Max Jitter.
Demonstration: Motion detection with Max MSP Jitter and a web camera.
Color Tracking with a camera.
Below are two samples of using the color RED painted on hands to create audio effects:

Kinect Sensor Cameras

Zach Lieberman has a lot of wonderful artworks, have a look at his website:
Here a Kinect is used to control lighting effects in real time (combine this with the Heart Beat monitor!)
Demonstration: Kinect sensor and drawing with Max Jitter and Windows
Physical Computing involves interactive systems that can sense and respond to the world around them.
Heart Beats are always an interesting way to make physical the unseen as we saw in the Sandro Masai video.
Arduino, the staple of Physical Computing
The hardware and software mirrors of artist Daniel Rozin are clear and entertaining examples of human computer interaction.
In this video, it’s interesting to watch how people interact with the works.
Here, Danny Rozin discusses one of his mirrors from his studio.

the coded gaze: face tracking
Tracking bodies and color are the ground work for artificial intelligence and machine learning. Face tracking is ubiquitous these days and, disturbingly, embedded with algorithmic bias.Joy Buolamwini (the poet of code) uses face tracking and art as research to illuminate the social implications of artificial intelligence.
Joy’s website is here for more exploration and information on her artwork: The Aspire MirrorJoy’s work with students to use face tracking to make video graffiti and projection mapping is documented here.
In-Ear sound monitors
These systems can be a little pricey, however you want a good system when using in performance!
Here is a link to an in-ear monitor system
Singers and musicians use in-ear monitors for pitch information and more.
For Annie Dorsen’s piece Yesterday Tomorrow In-ear monitors were used to provide metronome and pitch for the singers to use while they performed live sight-reading of a musical score.
watch an example here:
