This is the image that I chose to sketch. This is a picture I took back in my hometown when I was going out for a walk with my parents. It was quite near to the very end of the summer vacation, because of which I cherished the time a lot with my parents on… Read more Recitation 5: Processing Basics

Loneliness Killa-Ragnor Wu-Rodolfo Cossovich Our project is called “Loneliness Killa”, a communication aiding artifact that help one user convey primitive emotions and signals to the other user. CONTEXT AND SIGNIFICANCE Our previous research in the Group Project inspires my midterm project a lot. For example, one project I did research on, called “The Table” made… Read more Midterm Project

In this week’s recitation, we built a device that moves back and forth, similar to the piston of a car cylinder. We first studied the construction of the circuit. This circuit uses h-bridge, stepper motor and an external 12v power supply, so it is a relatively complex circuit. After carefully checking and connecting, we successfully… Read more Recitation 4: Actuators & Mechanisms

Loneliness Killa-Ragnor Wu-Rodolfo Cossovich This is a communication auxiliary artifact, which works privately between two people, connecting people on both sides in a humane, warm way, through heartbeat visualization, neon light patterns and also music player. It focuses on the social problems in modern society, that the vast development has caused modern people to have… Read more Midterm Project Individual Proposal

Project Description Prototyping Discussion Shortly after the result of the group assignment came out, our group members first met up together. We had a short group discussion together, to set up a general project direction which we may start from. The brainstorm brought us many ideas. Taking a few as examples, we had sleeping aid… Read more Group Research Project

In this recitation, we built an interactive device that simulates biceps bending.  Step 1: Firstly, we made an artifact by soldering the sensor with two long wires. Then, following the guidelines, we built up the circuits quickly. The circuits could read the status of the sensor as input and transmits them into my laptop. Step… Read more Recitation 3: Workout

Circuit 1: Fade In this circuit, we made a simple but interesting work. The circuit only consists of the power, the resister, the LED and the ground. We use pin D9 as the PMW input to control the pulse signal sent to the LED, through which we may control the brightness of the LED. With… Read more Recitation 2: Arduino Basics

The Veldt: From this article, I imagined a therapeutic device that can feel the changes of people’s emotions and project the corresponding situation. Most people in modern society have some mental problems. These psychological problems may originate from people’s poor emotional states. The artifact can detect people’s heart and brain electrical signals to feel people’s… Read more Fiction stories & Interactive artifacts

From my personal perspective, interaction should be a general process that contains the receiving, processing, reacting components of at least two sides that are involved in the process. According to Crawford, the art of interaction is ” a cyclic process in which two actors alternately listen, think, and speak”(5). Perceiving this from my definition, the… Read more What is interaction?

Task 1 For task one, we built a basic circuit. It is a simple circuit, with power, switch, and buzzer connecting with each other one by one. Switch controls the on and off of the electricity. Power provides electricity. The Buzzer would make sounds when the electricity is on. At first, we encountered some difficulties… Read more Recitation 1: Electronics & Soldering
