At first, we wanted to demonstrate color transition by spinning up an abstract pattern. While we were doing little test of it, we found that in comparison to show a color transition, it seems more interesting to create a motion graphic thing. Inspired by flip book, we came up with an idea of making an animation in a negative space between two spinning objects.

Our negative space animation is a girl whose mouth and hair keep changing as it spins. When you get closer to her, she would talk faster and if you step back further and further, she would gradually stop talking.

week 4 – motor

I was glad to learn about motors in our class so I created a dancing girl with soft fabric. Just before I made this, I took a soft lab workshop last week. It was fascinating to combine Arduino and fabric. So I decided to make a piece with moving stuff.

I bought a motor which can rotate 360° and I made a structure for a standing doll. Then, I sewed fabric for a motor cover and a dress. I covered the motor with fabric and placed a doll atop of it to keep the motor from moving around.

week 3 – IN / OUT

I tried to put multiple LED lights on the board and I used a sensor that responds to touch(pressing the sensor brightens the led luminescence).

I extended the button with longer wires so it’s positioning is not relative.

I tried to use acrylic material to illuminate the LED lights.

I laser cut acrylic into tiny pieces and stacked them together in a free flowing fashion.

I was hoping that light would spread out in a diverse direction through the material. What actually happened was that the light didn’t completely saturate all the way through the acrylic pieces. Some of the light leaked out of the material so only part of the material lit up. I felt as if the material’s appearance might change with light flowing through it by controlling how much light passed through.


*Observation  – Cooper Hewitt Design Museum Interactive Pen

  When I visited the Cooper Hewitt Museum, the museum staff gave me a pen and explained how to use it. I was curious what functions were included in this pen.

  There were interactive tables so visitors could collect information they liked and save them using the pen. Also, this pen works as a tool for drawing, so that visitor could explore actively rather than using museum App. Visitors can not only explore objects but also influence their view points. Traditionally, in the museum, the relation between visitor and object was not connected interactively with one another. Likewise, a visitor could not experience multiple perspectives. However, like this pen, It could be a tool to expand our view points regarding object and museum curating when we were in museum.


week 2 – Fun Switch

Clapping Switch

I started working with an Arduino board. The first thing I did was plug an LED into the board with a button and individual wires.


Next, I tried pressing the button to see if the LED would light up. After pressing the button, the LED lit up.

I drew two outlines in the shape of hands and filled in with my pencil. So both outlines contained graphite. I cut out the outlines and then taped to each outline an individual wire. I connected both wires to a breadboard.

I used with graphite on paper, kitchen foil, and conducive fabric.


week 1 – What is Interaction?

What I think interaction is, is a tool to communicate by using our innate senses. Basically, interaction functions like people talking with each other and gives people a means to communicate with an object.

It’s used in our life extensively. I would define physical interaction as using our senses to interact with things smartphones, tablets, and computers are all examples of interactive devices.

By using our senses we can listen, think, and speak with people, animals, interactive entities. For instance, two people shake hands, a treat is given to a pet, a utility pole provides electricity to our homes, touching a tablet to do something, wireless signals transmitting back and forth to a smart phone. All of these are real life examples of differing interactions that revolve around our lives.

Future Interaction

 What if we could interact with things through mind control? What if we could move something with our eyes? Imagine what that would be like! It would be an unseen connection like invisible radio frequencies. We could move physical and virtual objects through our will and thoughts. We could use our body to interact with things/objects. Just like what you see in a science fiction film. It would be like a pet sensing the heat radiating off our bodies without physically touching us.
