portraits of ambiguity by Daniel Shiffman
Daniel Shiffman, a professor at ITP have made this Led dispaly which light up the itp student's mug photo. Shiffman I personal think it is a strong critic of the realistic photography.

// Print a list of the serial ports, for debugging purposes:
println(Serial.list());

[ the led display on the stage ]
• the lighting is incredible fun to look at, which is designed byUnited Visal Artist
[we all look very red, becuase all the lighting is putting on to the viewers. after a while my eyes is a little uncomfortable. ]

midterm: rfiders
SkyeModule™ M1 & RFID sensor
[ Process ]
green LED = circle = approved
red LED = cross = denied
blue = put your rfid on the top of it !!
[testing with the plastic cover ]
* the blue and red led work perfect underneath the plastic
* the green is not as bright as the blue and red, so we will build more in.
[ putting everything together }

[ INTERACTIVE INSTITUE ]
Interact Institute is very thoughtful IT-research institute from Swedon.
The Flower Lamp is one of the interesting products that I saw in their boot.
The flow shape lamp will open and close depend on how much energy that people consume in the space. The lamp is a reminder mahine that is not too annoy with all kind of sound but having this suttle visual movement to the users.
[ LED CUBE]
I met James two years ago in one of the Chealsea art galleries. He was documenting his work, while I was wondering about how he made the Led lighting Cube. He is also the person who introduces ITP. His work really engages with the viewers. At that time, viewers have to wear 3D paper glasses to see the three dimensional illusion. This time the led cube became a product and James also establishes his company now.

The Illusion Machine [ servo / button ]
Illusion Machine is a collaboration piece by Younghyung and aichen. The illusion Machine is to response the show Moving Pictures(American Art & Early Film, 1880-1910) at Grey Art NYU Gallery.
The connection:
detail:
final installation:
The code:
int servoPin0 = 2; // Control pin for servo motor
int servoPin1 = 3;
int minPulse = 500; // Minimum servo position
int maxPulse = 2500; // Maximum servo position
int pulse = 0; // Amount to pulse the servo
int rotating_duration = 20000;
long lastPulse = 0; // the time in milliseconds of the last pulse
int refreshTime = 150; // the time needed in between pulses
int analogValue = 0; // the value returned from the analog sensor
int analogPin = 0; // the analog pin that the sensor's on
boolean direction = true;
long count = 0;
void setup() {
pinMode(servoPin0, OUTPUT); // Set servo pin as an output pin
pinMode(servoPin1, OUTPUT);
Serial.begin(9600);
}
void loop() {
if (direction) {
pulse = minPulse;
if (count++ >= rotating_duration) {
direction = false;
count = 0;
}
}
else {
pulse = maxPulse;
if (count++ >= rotating_duration) {
direction = true;
count = 0;
}
}
{
// pulse the servo again if rhe refresh time (20 ms) have passed:
if (millis() - lastPulse >= refreshTime) {
digitalWrite(servoPin0, HIGH); // Turn the motor on
digitalWrite(servoPin1, HIGH); // Turn the motor on
delayMicroseconds(pulse); // Length of the pulse sets the motor position
digitalWrite(servoPin0, LOW); // Turn the motor off
digitalWrite(servoPin1, LOW); // Turn the motor off
lastPulse = millis(); // save the time of the last pulse
}
}
}
Observation Assignment:
1.counting daily uses
iPod user: move their fingers on the scroll panel
subway ticket : swipe the card on the machine
elevator: use the button to indicate the floor.
Palm: use the pen tool on touchable screen to write and select the options
2. in depth observation
NYU student ID swipe action
SETTING : a digital swipe machine
PHYSICAL ORIENTATION: people walking pass the machine and sometimes have to stop in front of it.
PHYSICLLY DO :
first: take our the card
second: flip one or two times to figure out which side is the right one.
third: insert the card
fourth: may be able to walk through or have to try again on the other side.
total: could be 4 steps or more.
＊missunderstanding of using the NYU ID in comparison to subway card is debilitating user's effort.
＊the illustrated instruction doesn't fully give a clear direction to the user
Lab Week4 : anolog in/ digital out [ distance sensor / lighting ]
[ codes ]
int threshold = 350;
int ledPin = 9;
void setup(){
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
}
void loop(){
int analogValue = analogRead(0);
Serial.println(analogValue, DEC );
if (analogValue > threshold) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
delay(10);
}
[ The Tips to install the audurio from Tom Igoe ]
First, with 10.3.9, you should use Arduino 0004, not 0005.
Second, make sure you've run the FDTI driver install from the drivers
folder before you plug it in.
Third, make sure you've run the macosx_setup.command script by double-
clicking on it and following the instructions it gives.
Fourth, restart Arduino.
Fifth, make sure the poer jumper is set to the USB side.
Failing all of that, check the forums on the arduino.cc site for more.
