WiiJ Timsky http://www.wiijtimski.com

Timsky is a WiiJ and a former intern with Frank at STEIM. He wanted a physical interface that would allow him physical freedom on stage as well as reliability and accessibility.

He uses the wii remote which has two sensors: the IR sensor which is not useful for this and the 3d axis accelerometer.

He then demo’ed his setup and admitted that he had made his own version of junXion.

He would have liked to be able to adjust the bpm by smashing, but he is using a circular turn-up-the-volume motion instead.
He can move freely but he needs visual feedback on the screen to know what he is doing
The margin of error is small but it is still there.

Timsky then did a short demo of the wii guitar setup and he almost had the room dancing by the end… or at least bobbing their heads.

Atau Tanaka / The new Biomuse http://www.sensorband.com/atau/

The timing for this demo is very good, the new version of the instrument was finished yesterday. This means that there is a distinct “before” and “after” in the history of the instrument.

Bckground: The Biomuse picks up neural signals in the arms in the 4 muscle groups: inner arm and outer arm, on the left and the right arm.

Atau started by demo’ing the “before” Biomuse. Showing us the quality of the signal and the processing he does in MAX. It is a very lively signal, it requires some smoothing. The instrument is very gestural but it does not nessesarilly require motion. It is running on a laptop, but it should not be a laptop performance.

The “after” Biomuse: The instrument has been extended with non-bio-sensors and gloves. There are push button switches on the palm of the hands and tilt switches on the arms.

Atau has stayed with these sensors because it feels good. It is an instrument that he has lived with for a long time, in a way it is a new instrument now and he will now have to learn to play it from scratch.

uOSC and Firmata - Sensor Interface vs. Single Board Computer

Tuesday, December 9th, 2008

The uOSC project reminded me of the Firmata project for Arduino. It is similar in that it is also an abstraction layer for the micro controller hardware and moves the coding from the micro controller to the host computer and in the process hides much of the low-level complexities of the hardware. It is different in that uOSC puts more emphasis on performance and timing accuracy than Firmata on Arduino can offer.
That said, you need to be familiar with OSC and still need to know about port pins, adc and pwm to make any good use of such a shift in paradigm.
It also (re)opens the debate of the Sensor Interface vs. Single Board Computer point-of-view in  looking at hardware like Bit Whacker or Arduino. uOSC or Firmata places the application on the host and reduces the hardware to a sensor interface, whereas this hardware can also be used (and has a big reputation) as a stand-alone physical computing device in its own right, if programmed in its native language stored in on-chip Flash memory.
That said, I think uOSC is a great way to open up the world of physical computing to the MAX/MSP community and other users fluent in OSC but not so much in low-level coding.
Great job, Andy!

Andy Schmeder (CNMAT Researcher, Developer of uOSC) - uOSC
OpenSoundControl framework for USB and multiple sensor platforms

Andy talked about Micro OSC and he gave one of those talks where you get so caught up in following the talk, you cannot type as you go. So the following is unlikely to be complete or correct, but anyway - here is what I managed to put down:

Andy’s first slides illustrated the connections between innovation and music and how the connected issues and concerns enable and mutually enable each other. Music generates an interesting array of use cases and they tend to expose complex issues of interaction and interfaces.

Sukandar Kartadinata (Instrument Designer, Gluion Developer) - Developing sensor instruments and platforms for artists http://www.glui.de/

Sukandar talked about sensor interfaces. He started by outlining three interfaces: The Sensorlab, the Gluion and the Arduino.

The Sensorlab was the first sensor interface for musical instruments and in fact that is how Sukandar got started when he came to STEIM in 1992. The Sensorlab was made for live electronic interfaces and at the time STEIM was the place to go to if you wanted to do this. Of course today if you ask people about sensor interfaces everybody talks about the Arduino board. The Gluion is different to both the Sensorlab and the Arduino.


Andy Schmeder : micro-OSC

Tuesday, December 9th, 2008

At CNMAT, Music and Research a mutually reinforce each other. Part of the overall concept behind micro-OSC is to try to minimize user error when building new interfaces. Eliminating the need for the end user to write microcontroller firmware is therefore a goal of the project. Nearly the full feature set of USB-enabled PIC microcontrollers (ADC, PWM, GPIO, etc) are made available to the user through higher-level host-computer based software.  The home page for micro-OSC, including a download link is found here, and there is some documentation here.

Support for several microcontroller boards is provided with micro-OSC:

USB Bit Whacker - up to 10 ADC inputs, 12-bit resolution
CREATE USB Interface (CUI) - up to 13 ADC inputs, 12-bit resolution
Olimex USB board - up to 13 ADC inputs, 10-bit resolution
