Introduction
• Roland Corp. (1993∼2004)– Sound designer– Software engineer
• IAMAS (2004∼)– Physical computing– User interface
Introduction: Make Magazine (Japanese)
Make: Technology on Your Time Volume 04O’Reilly Japan (2008)
Background: Gainer
A toolkit consisting of open-source hardwareand software
• Gainer I/O module– PSoC + FT232RL
• Software libraries– ActionScript 2/3– Processing– Max/MSP
Background: Gainer
Open-source hardware
• Gainer PSoC Development Board– Designed by SparkFun Electronics– PSoC based, low cost
• Ginger/Pepper/Sugar– Designed by Morecat Lab– AVR based, low cost

Motivations to Funnel
Found problems
• An I/O module doesn’t cover all user needs,& changing between toolkits is expensive
• For beginners, it is still difficult to handlereal-world inputs
• Wired connection narrows ideas during‘sketching in hardware’ stage
What is Funnel?
• A toolkit to interconnect toolkits• Covers from sketching to prototyping• Intended to be a common language
between designers/artists and engineers

Funnel: Pseudo code like programming
Example 1 Ruby×Funnel×Arduino Nano
# Control brightness of a screen by a pot
def setupsize 400, 400@aio = Arduino.new :applet => self
end
def drawbackground @aio.analog_pin(2).value * 255
end
Funnel: Pseudo code like programming
Example 2 Ruby×Funnel×Arduino Nano
# Apply a filter to smooth inputs
def setup...@fio = Arduino.new :applet => self
f = Convolution.new Convolution::[email protected]_pin(0).filters = [f]...
end
...
Funnel: Pseudo code like programming
Example 3 Ruby×Funnel×Gainer I/O
# Start blinking the LED when the button is pressed
@gio = Gainer.new@osc = Osc.new Osc::SQUARE, 1, [email protected] = [@osc]
@gio.button.on RISING_EDGE [email protected]
end
Funnel: Pseudo code like programming
Example 4 Ruby×Funnel×Gainer I/O
# Turn on the LED after dark
@gio = [email protected](0).filters = [SetPoint.new 0.3, 0.1]
# threshold, hysteresis
@gio.ain(0).on FALLING_EDGE [email protected] = 1
end
