Unveiled and exhibited at the 2011 SPOT Festival in Aarhus, Denmark – RADARTABLE flipped the conventional view of what to expect from a concert or musical experience on its head. RADARTABLE is an interactive, audiovisual installation, a musical instrument, and a platform for creative and social interaction. It allows the audience to express themselves musically and collaborate with each other to influence their concert experience – even if they normally have no prerequisites for playing music.

Sight Unseen: Envisioning the Virtual

Public lecture by Professor Brian Massumi, Département de Communication, Université de Montréal, Canada.

The lecture will examine the status of the virtual in perception. As understood philosophically by thinkers such as C.S. Peirce, Henri Bergson, William James, Gilles Deleuze and A.N. Whitehead (in his notion of “pure potentiality”), the virtual is strictly complementary to the actual. It is a mistake to think of them as opposites or as in contradiction. The virtual is abstract by definition, which means that it cannot be reduced to the empirically present. But neither can it be separated from it. According to the philosophical concept of the virtual, there is a reciprocity between the actual and the virtual that enters actively into the constitution of every act of experience: they are co-gredient to perception. Although the virtual as such cannot appear in perception, its co-gredience to the constitution of experience cannot but make itself felt in some way with each perception’s arising. The question then becomes, in what way does the abstractness of the virtual come with coming perception? How does it make its active implication in experience felt? Applied to vision, this question translates into: what is a virtual image?

Affective Experience as a Theoretical Foundation for Interaction Design

In connection with the submission of his PhD dissertation

Affective Experience as a Theoretical Foundation for Interaction Design

to the Faculty of Arts at Aarhus University for the award of a PhD degree in Information and Media Studies, MA Jonas Fritsch will publicly defend his research in open forum

13-16 on Wednesday May 4, 2011 in ”Det lille Auditorium” Incuba Science Park, Åbogade 15, 8200 Aarhus N

The dissertation Affective Experience as a Theoretical Foundation for Interaction Design explores how the philosophy of Brian Massumi on affective experience can be used as a new theoretical foundation for interaction design. It is outlined how there is a need for interaction design to inquire into new philosophical accounts of how people experience interactive products and environments rather than what constitutes an experience.

PUBLIC LECTURE: Media Archaeology As Topos Study

by Professor Erkki Huhtamo, University of California Los Angeles.
Friday April 29th, 10:15-12:00, Lille Auditorium, Incuba Science Park

This lecture discusses media archaeology by developing a theoretical-historical contextualization of the topos, a notion adopted from the literary scholar Ernst Robert Curtius and turned into a “tool” for explaining the recurrence of clichés and commonplaces in media culture. Huhtamo has applied the idea to various media forms ranging from “peep media” and the moving panorama to mobile media. In this intervention the approach will be delineated theoretically, discussing its predecessors and demonstrating how it can be applied to various facets of media culture. The task is identifying topoi, analyzing their trajectories and transformations, and explaining the cultural ‘logics’ that condition their ‘wanderings’ across time and space. Topoi are discursive “engines” that mediate themes, forms, and fantasies across cultural traditions. Predictably, they have become a tool in the hands of the culture industry

DUL Radio

April 2012-update.

DUL Radio is a piece of hardware/embedded software for physical interaction prototyping. The hardware has reached a final version 1.0, while the software is still under development. It does however run in a solid beta-version.

DUL Radio is wireless, it communicates sensor data via FM radio-transmission, hence the name.

It´s intended to provide a neat trade-off between complexity and efficiency, especially for interaction designers and digital artists working with sensor-based interaction.

DUL Radio is not a commercial product. Although it may be at some point. Eventually DUL Radio will be licensed as open source.

The hardware is available in limited quantities, being used internally for teaching audio and interaction design as well as in artistic projects. If you're interested to know more details, shoot us an email (you´ll find contact information at the bottom of this site).

DUL Radio hardware key features:

-All key components are integrated on one circuit-board: processor, terminals, power, wireless transmission circuit, antenna and even a 3D accelerometer.

-It´s small, 2.5x4.3x0.6 cm - Bear in mind, this is with all components.

-Atomization; It has centralized recognition of several communal independent data-streams: That is; the receiver can communicate with up to 4 DUL Radio´s simultaneously. With each DUL Radio having 2 terminals for analog sensor attachment and 1 3D accelerometer it makes a total of 8 sensor points and 4 accelerometers communicating from up to 4 different positions to one central receiver, simultaneously and synchronized.

DUL Radio software key features (to be expanded):

-Interfacing with several host applications, such as Max5 and Max6, Processing and Unity is possible. Basically anything that can read from a serial port can communicate with DUL Radio.

-Low level power handling that supports robust and very efficient power use, making the DUL Radio able to run for days, even with "realtime" continuously active analog sensors attached. This is thanks to the Alexandra Institute engineering guys who did a really neat job here!

-GUI-interface level to several low-level parameters, such as independent sample-rates and complex sleep/awake functions. These parameters are accessible in a so called Configuration Mode using a piece of custom software that can be downloaded from this site, (see "CONFIGURATION APP" further below).


So far, two papers has been published about DUL Radio.

One presented as a work-in-progress-paper at the Tangible and Embedded Interaction Conference, TEI2011TEI2011, in Madeira, Jan. 2011

And the final paper presented at the Tangible and Embedded Interaction Conference, TEI2012TEI2012, in Kingston, Canada, Feb. 2012

Final PaperFinal Paper


DUL Radio has been tested with and runs under Mac OSX 10.5.8, 10.6.8 and 10.7 as well as Windows7.



The DUL Radio receiver does not require a driver to run under OSX.


The DUL Radio receiver requires a driver to run under windows7.

(NOTE: you´ll have to give win7 manual access to unpack and install the driver, due to some microsoft encryption mumbo jumbo).

Windows Driver 32bitWindows Driver 32bit

Windows Driver 64bitWindows Driver 64bit


Both communication with host-software and the custom Configuration App requires java-installation.

This is on both OSX and Windows.


Since Java is part of the OSX-install, the DUL Radio will be readily available in the standard data transmission mode.

This goes also for Java5 in OSX 10.5.8. However, the Configuration App only supports java6 (and up).

Therefore make sure that the correct java version is installed and positioned correctly:

Go to Root/Applications/Utilities/Java Preferences:

In the General window-pane, make sure that Java SE 6 64bit or 32bit (depending on the mac you use), is at the top of the list.


Since Java has to be installed manually, simply make sure to download and install the version your Windows system supports (32 or 64 bit).

DUL Radio and the SERIAL PORTS:

Several virtual serial ports are accessible via USB. Therefore several receivers (USB Stick´s) can be attached to one computer making it possible to receive data from X4 DUL Radio´s on the same computer. When doing so it is however very important to keep track of which receiver is communication with which serial port.

Likewise, it is possible to receive the data-streams from one DUL Radio in more than one host app simultaneously. The proper way to do so is to setup one of the host app´s to be the mother-host addressing the serial port and from there stream the data via a networking protocol to the other app(´s). This can be done using OSC/UDP or the like. Do not address the serial port from several host´s at the same time.


The Configuration App is still in an early state of development, but provide access to a vital part of the DUL Radio idea.

It handles the high level access to the parameter-based control of the processor. Thus making it possible to have fairly easy access to among other things; variable sample-rates, power handling and sleep/awake-functions.

A screenshot of the Configuration App.

An explanation of the parameters is available when positioning the mouse over the parameter names.


A guide on how to configure DUL Radio in the Configuration App:

  • The following only apply to OSX:
  • -If you do not have a folder called "lock" in your root/private/var-folder,
  • then please follows these instructions.
  • -In Finder mode: Choose "Go to Folder…" in the "Go" menu, write: /var and click "Go".
  • -If you do not have write permission to the var-folder, create a folder called "lock" on the desktop and copy it into the var-folder
  • -Under all circumstances, make sure that you have read/write privileges to the lock-folder: cmd/i the folder and give "everyone" "Read & Write" Privilege under "Sharing & Permissions".

  • The Configuration App:
  • 0. Insert the USB stick into the computer.
  • 1. Make sure no DUL Radio´s are turned on (while the ADC-ports are pointing upwards, press the left button to turn them off)
  • 2. Open the Sensorboard.jar application in the ConfigurationAppAlpha-folder.
  • 3. Reset the USB-stick (press the button furthest away from the computer).
  • 4. Make sure the right serial-port is chosen.
  • 5. Still with the ADC-ports pointing upwards; press both buttons on the DUL Radio, release the right one first.
  • Both LED´s light up - if not, there is no power left on the battery.
  • 6. Wait until both LED´s start to flash, Click "connect" in the Sensorboard.jar app.
  • -If the LED´s do not start to flash, connection has failed, close the app and please go back to step 1.
  • 7. You have now access to the configuration panel. When done configuring, click "Configure sensor board"
  • 8. Press first right, then left button on DUL Radio.
  • 9. Quit Sensorboard.jar app.
  • 10. Make sure all DUL Radio´s are turned off, repeat step 2-9 for every DUL Radio you want to configure.

  • NOTICE: The USB Stick´s LED lights continuously red when in configuration mode.
  • When it receives data from the DUL Radio´s, it lights green in a pattern reflecting the data-transmission.
  • When the DUL Radio´s are off, the USB Stick is in idle mode and flashes an orange light approx. every second.

HOST SOFTWARE (To be expanded):

Max5 & Max6:

To run the DUL Radio in Max, one vital element is neccesary;

A couple of java class files must be downloaded and placed here:

OSX: root/Applications/Max5(or Max6)/Cycling '74/java/classes

Windows: Program Files/Cycling '74/Max5(or Max6)/Cycling '74/java/classes

NOTE: There are two versions in the zipped file: a 32bit version and a 64bit version. Use the one that fits your system.


A couple of Max-patchers has been made, to provide easy access to monitoring DUL Radio data in Max. Make sure that the java class files in "JavaInMaxforDULRadio" are in the right place and that the USB Stick is attached to the computer, before starting up Max. In Max, open the "DUL-Radio4ch" max-patch, the other two patchers are sub-patches. Start the DUL Radio (press the right button with the analog ports pointing upwards), now accelerometer data should be visible in the monitor.



DUL Radio can communicate with the Processing software through a library developed by Lasse Vestergaard.

Download the zip-file below, unzip and place the "DULRadio"-folder in the /Documents/Processing/libraries directory.

Open the /Documents/Processing/libraries/DULRadio/examples/Hello in Processing.


In relation to DUL Radio and Processing:

DUL Radio was conceived in 2006 by Rasmus Lunding and developed in an early test version by Peter Friis and Anders Ebert. Since 2008 it has been re-developed, as part of DUL and the project "Byens digitale liv" in a partnership between Dept. of Aesthetics & Commincation (previoulsy: Dept. of Information & Media Studies) and the Alexandra Institute.

New book: Interface Criticism – Aesthetics Beyond the Buttons

"Interface Criticism – Aesthetics Beyond the Buttons" is a new book edited by Digital Urban living and Digital Aestetics Research Center (DARC).

Interface Criticism is not another design manual but a critical investigation for readers interested in the aesthetic, cultural and political dimensions of interfaces. With contributions from leading researchers within the field, the book covers a wide range of aesthetic expressions – including urban screens, wearable interfaces, performances, games, net-art, software art, and sound art, and discusses how new cultures evolve around, for example, open source or live coding.

In conjunction with the conference, Public InterfacesPublic Interfaces, we have a book launch reception on wednesday januar 12, 16.00 at the Foyer, Ridehuset at Kasernen/Aesthetics, Langelandsgade.
