Enhancing and enabling playful, creative interactions

Semblance Typology of Entrainments

These english words are built from Greek or Latin prefixes for "same" or "together" or "with". There are many others still to be explored, .e.g. ,

synonym - together in meaning

synorogeny - form boundaries

conclude- close together

symptosis - fall together

symptomatic - happening together

symphesis - growing together

sympatria - in the same region

symmetrophilic - lover of collecting in pairs

synaleiphein - melt together

Conductive Paper Pressure Sensor and Arduino Teensy

Overhand knot in a strip of carbon-loaded paper becomes an FSR that can be easily connected to your favorite microcontroller (in this case a teensy running with the Arduino C++ tool chain).

Wearable Video Game Platform Bracelet

This bracelet has an Arduino-powered ring of white LED's with a 3-axis accelerometer tilt sensor.

How many interactions/games can you think of with this platform?

There are 3 in the video:

Hand in the air: flashes (because at a party you want to signal that you want someone to talk to?).

Horizontal hand: always illuminates the top LED's whatever rotation your arm has ("smart flashlight")

Spins of the wrist: a blob spins around in the same direction and slows to a stop.

OSCuino rough Arduino OSC sketch for Open Sound Control work

This example uses the recommended OSC SLIP wrapping for OSC serial messages. Attached is an example Max/MSP patch to display the OSC messages which represent the pin states, temperature and power supply voltages. You may need slipOSC from the CNMAT downloads page to unwrap the USB serial OSC. This is a simple introduction to building OSC messages. Yotam Mann has built a complete library for Arduino that does the full OSC protocol It is available from CNMAT. This example uses the recommended OSC SLIP wrapping for OSC serial messages.

Stanford HCI Seminar : Anti-Ergonomy of Instruments of Interaction

See video
Antiergonomy rules. I use the idea of anti-ergonomy to pierce the veil of objects imbued with charismatic authority (holy water, iPhone, etc) and expose the often contradictory value systems of the stakeholders. A quick illustration:l Let's look at the french baguette. It has a number of features of value to the baker that are not ergonomic to the buyer. It is made of white bread and of less cost and nutritional value than whole wheat. It goes stale fast so you have to go back to the baker several times a day and it is too long to fit in bags so it sticks out advertising itself.

Better Arduino alternatives

I don't use the stock "official" Arduino boards for my work. The $18 teensy 2.0 is smaller than any of the stock Arduinos, has more A/D pins than any of them except the Mega, has more memory, more PWM pins, full speed USB serial support and has a more accurate crystal cock instead of a resonator.

Wiimote, Nunchuck and Inertial Sensor Hacking for Music and other Interactivity

I presented various Wiimote alternatives such as the Gametrak, how to interface Nunchucks to uOSC and a quick tutorial using Max/MSP for gesture signal processing.

Taming the Media Monster: Rich Media Blogging for Drupal

See video
Drupal modules exist to implement best practices in web interactivity for a wide range of media types.Taming coding bugs, configuration challenges and coherent theming for these modules is a real chore. I will share successful techniques I have employed in developing a recent rich media site covering:

The Fingerboard Instruments: Reframing Lutherie without Strings

Recent attempts to extend organology to add useful classifications of electrophones and music controllers have rightly focussed on music performance gestures . The naive approach of classification by gestural types (strum, pluck, hit, slap etc..) fails because gestures say more about musicians and their music than their instruments.
