Cell Phone Xylophone was originally developed as part of PORTAGE, an artist and designer driven research project, led by Geoffrey Shea and Paula Gardner in the Mobile Experience Lab. It allows participants using a simple cell phone to control and play a networked, mechanical instrument. Created with Rob King, Ken Leung, Peter Todd, Leighanne Pahapill, Patricio Davila and Jennie Ziemiannin.
Viewers simply dial a toll free number and are then prompted to enter key presses. The patterns they enter correspond to arpeggios and loop several times. Their phone connects to a VOIP service which delivers their key presses to an Asterisk server which relays them to the control machine wired up to the xylophones custom controller board. This version was presented at MobileFest in Sao Paolo, Brazil. See more at www.mobilelab.ca.
