Hannah & Julien

1. Semester Topic

Our initial idea was to experiment with Arduino, Processing, sensors and interactive technology. Our way to develop a general topic is by experimenting with formal & digital ideas & learning how things can be used.
During this experimental process we found out that we want to focus on unconscious movements of our bodies we are usually not aware of.

2. Media, Material we are interested in

The media shall be an interactive installation.

We would like to use the cooperation (“handshake”) between Arduino and Processing to enable the installation to react to certain movements the observer is doing.
Therefore we would like to use and experiment with different sensors.

We would like do visualize the bodies involuntary movements like:
heartbeat, blood pressure, body heat, EKG, finger print

3. Whats the aim and our purpose?

We would like make the experience of our uncontrolled life possible.

The “handshake” between Arduino and Processing enables the animation to change under certain circumstances (for example if the beholder is coming closer).
After a certain signal a picture will be taken and will be directly appear on a website.

4. Whats our process?

At the moment we are working and experimenting with Processing and Arduino especially the “handshake” – the cooperation between these programs.

We will experiment with sensors.

We will experiment with sensors.

There will be a website to be designed.

More detailed & deepened description will appear shortly.


We already did some experiments with Arduino:

Now we are in the experiment of changing a Processing animation we found online (Gizmo) in turning a potentiometer on the breadboard.

You can see the result as follows:


The “speed” of the single particles in the animation changes by turning the potentiometer manually in real time. The value (0-300) was mapped and can be seen in the lower left corner.



Experimenting intensifies…

We first had an idea for the final project that involved a closed-meshed net that should be moving with the help of thin threads and illuminated with a beamer. Well… that didn’t quite hit the mark. After building a prototype, we realized that we couldn’t achieve the effect we hoped for.


After experimenting and having some long and intense brainstorming sessions and discussions, our new idea of how our project will look like is the following:



An interactive light installation on the wall. The area will be divided into a 3×3 grid.
Each part will inhabit a neon tube. It will be fixed so they can move like a screw.
These light tubes are interactive: As soon as somebody uses the sensor to mess his pulse the tubes will start to rotate.
They will move quicker, slow down or will be dimmed when the arduino is receiving certain information from the sensor or another interactive signal.
Once the beholder strides away or stops the disconnects the sensor the installation will stop moving and a certain image & pattern will be frozen.



An interaction between the beholder and the installation is assembled as soon as they are connected via the sensor. The movement of the tubes are a visualization of the persons movement and reactions. Afterwards the interaction leaves a frozen pattern consisting of nine bright circles or light sticks which remain as strong graphic forms.

We would like to create a website to collect all the different movements and patterns generated by this interaction.

Since we are following a process orientated approach, our idea of the end product changes constantly, but the core concept is getting clearer and stronger.

The exhibition should now be a small dark room and on one end of the room shall be a single LED strip.
A sensor records the pulse and data of the 
beholders heart.
Subject to the sensors data the light will start to rotate and dim itself in a certain rhythm.

The light visualizes the movement and therefore our inner bodies functions. As the beholder will be on its own, everything will be concentrated to the essential of this single light.


Here’s a first sketch of how the room should be installed.



Ideally, we would like to use the photo laboratory in our university. To enter this room, you need to go through a revolving door.
When you come out of the door, the only thing you can see is a stool, a table with the pulse sensor and written instructions for the correct use, illuminated by a little lamp. The rest of the room is completely dark.
When you plug yourself to the pulse sensor and the Arduino board recieves a signal, the little lamp goes out and the light installation on the wall starts.
To achieve the darkness, we would use some molleton on either side of the room.
This way you are left completely alone with the light controlled by your own heartbeat.
When you take off the sensor, the installation turns off and the little table lamp goes on again, so you can find your way out again.

We will additionally build a website that shows videos and further information of the installation and will be accessible on an iPad in the projects main exhibition room on the first floor, accompanied by a light and deep heartbeat sound to build a link to the installation located on the third floor..


Before constructing our final twisting LED light, we want to visualize the effects and possibilities of the LED strip. For that, we are using a code that our teacher prepared for us in Processing, representing the turning LED strip. We try to find some interesting shapes that appear when the lamp and the LEDs are moving and to translate our ideas into code.
