Workshop at University of the Arts Berlin | 1. December 2017

In her book »The Function of Ornament« Farshid Moussavi describes visible and invisible forces that will shape the architecture of the future. The combination of new mechanisms with cultural, political and temporal effects will manifestate in new aesthetic compositions and affects. In the workshop the participants will concentrate on the visible forces (structural, functional and physical) to develop paper prototypes for future exhibition designs in the context of »Media in Space«.

Session 1 => Paper Folding

Example Structures

paper_folding_structure_001.jpg paper_folding_structure_003.jpg paper_folding_structure_005.jpg paper_folding_structure_006.jpg paper_folding_structure_004.jpg paper_folding_structure_002.jpg

Look at the above structures and set them into an architectural context. Imagine those structures to become a carrier of information using different media: For instance printed images (e.g. as anamorphosis), or medial augmentation (e.g. through projection mapping) – in combination with the right media such structures create interesting spatial environments to transmit content.

Session 2 => Shortcut for switching layer compositions in Photoshop

My favourite Photoshop feature is the layer composition tool. A layer comp is a snapshot of a state of the Layers panel. To switch between different layer comps you can click onto the arrow-icons (see red box in screenshot below),…

…or create an individual short-cut. The screenshots below lead you through the steps of how to create such a short-cut.

Session 3 => Arduino Sketch

// Including necessary libraries
#include <CapacitiveSensor.h>

//10 Mega Ohm Resistor between pins 7 and 8, you may also connect the antenna on pin 8
CapacitiveSensor cs_7_8 = CapacitiveSensor(7, 8);

// Declaring required variables
unsigned long csSum;
bool initial = true;
char val;


// Initial setup that runs only once in the beginning
void setup() {
  // Initiating the serial connection between Arduino and computer
  Serial.begin(9600);

  // Letting Arduino know that the builtin LED will be used
  pinMode(LED_BUILTIN, OUTPUT);
}


// Main program loop
void loop() {

  // The loop for the inital handshake with the Processing code
  // Basically, Arduino board broadcasts "1" to the computer until
  // it receives "2" from the computer. Later, Arduino sends "2"
  // back to the computer to show that it received the message
  while (initial) {

    // Keep sending "1" to the computer
    Serial.println("1");

    // Wait for 50 milliseconds
    delay(50);

    // If any data is available to read from the serial connection
    if (Serial.available()) {
      
      // Read it and store it in val
      val = Serial.read();

      // If the read value is 2
      if (val == '2') {
        
        for (int x = 0; x < 5; x++) {

          // Send "2" to the computer

        initial = false;
      }

  // Read the pins and communicate with the computer
  // This function does the main job of letting the
  // computer know that someone has touched to the pin 8
  CSread();
  
}


// Function definition
void CSread() {

  // Sensor resolution is set to 80
  long cs = cs_7_8.capacitiveSensor(80);

  // Arbitrary number to detect the chnages
  if (cs > 100) {

    // Accumulate the reading values
    csSum += cs;

    // This value is the threshold, a High value means it takes longer to trigger
    if (csSum >= 4000) {

      if (csSum > 0) {
        csSum = 0;  //Reset
      }

      //Stops readings
      cs_7_8.reset_CS_AutoCal();

      // turn the LED on (HIGH is the voltage level)
      digitalWrite(LED_BUILTIN, HIGH);

      // Send "1" to the computer to indicate that button is activated
      Serial.println("1");

      // Wait for 50 milliseconds
      delay(50);
      
    } else {

      //Timeout caused by bad readings
      csSum = 0;

      // turn the LED off by making the voltage LOW
      digitalWrite(LED_BUILTIN, LOW);
