touch me – section 2 lab
This is a touch interface for controlling sound and video.
A capacitive proximity sensor made out of tinfoil is placed underneath a fuzzy fabric and attached to a max patch. In its dormant state the patch creates a quite low tone. As one reaches out to touch the fabric the frequency of the sound changes and video effects intensify. The change in frequency and intensity of video effects varies with the distance of one’s hand from the actual sensor. Thus by rubbing the fabric the user becomes conscious of his/her control of the sound and video and is able to creatively interact with the fabric.
Capacitive Sensor: two wires from pin 8 and 9 with a 1M resistor between them; another wire connected to pin 9 running to the strip of aluminum foil. Code and sensor design were acquired from the following arduino forum thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1171076259
