The title of this project is the Intersection. Originally, intersection is used to mean “a place where two or more roads meet; junction.” In an intersection various cars intersect with other car. Some people pass through the intersection In order to get to work, others may be on a trip to pick up someone. People who are in a hurry may also pass through it. On the other hand, people pass through while singing ho-songs. In addition, not only cars, trucks and buses, pedestrians, runners, even animals may be visiting the intersection. The intersection is considered as a place where such various things come and go. Diversity is one of the most important term in my project. London is a diversity city where people come from many countries. Though the scale is too large in the country and city. I should focus on small area and scale.
Intersection
However, what is the place with diversity? Airport? Is it an office building? There is a diversity that the place people gather such as London or nature. In a diverse space I believe even though they are not conscious of each other, they may have a slight influence on each other and something may be brought. Serendipity is not hard to be delivered in an environment with diversity. I think that it’s important to make accidentalness in an environment. In other words, I would say to divide the thing that can be controlled and uncontrolled and

think importance of designing uncontrolled things. The trivial machine is introduced Heinz von Foerster, is a one-to-one relationship between machine and human. It’s is a simple input and output relationship such as a toaster. In this project, I tackle on my work combination with multiple trivial machine and explore continuous changing situation on my work. Since trivial machine is a predictable system, normally people is getting bored soon in the trivial machines’ space. However, it is nearly impossible to create a non trivial machine that is more complicated and difficult to realise. So, I decided to make the trivial machine more complicated by making multiple trivial machines. One of my goal in this project is that my work functions as a black-box for a visitor. Machines are characterised as heading to be stable because machines are essentially only repeating simple electrical signals. In order to solve its characteristic, I have to incorporate not only digital technology but also analog elements. It is a visitor’s moving in the space, how visitor will move is unpredictable, so it is compatible with sensors. As the visitor move, the sensor reacts, the lights gleam, the rods sway. As much as possible, I designed not only to have a one-on-one relationship but to respond by a third person around. Even though the visitor wanted them to gleam, it might not be the case. This is my another goal for the project. For that reason, this space is designed to be 3.5 m x 3.5 m.
The Previous Project Summary
This project is further developed from the previous project. The previous project reflects Primrose hill’s site research, which is located in London, and chosen for the project. As a result of doing site research, I found some informal paths in the park. It was obvious that this informal path was not designed by the designer but was made over time by visitors using the park. The way and direction of walking in the park is basically free and up to visitors. What is suggested from those is that the designer has nearly impossible to completely control the space and that there is no need to do it. Visitors naturally find ‘affordance’ in space. The result is this informal path. Since grasses grow around the path, I tried to unify the grass of the park with my project work along the circulation.
Informal path in Primrose Hill and Elevation in the site
Interactive grass Interactive grass are designed that blend right in with environment of the Primrose Hill, especially with covered grass. However, it can respond to the motion that people walk around the works using Arduino and a motion sensor. When it catches the motion of someone near the work, interactive grass is luminous and continue to gleam for a few seconds.
Interactive Grass almost covered by grass
Outcome for the previous project
Material Materials for this work should be carefully selected because grass usually swings when wind blows. I chose the materials which can swing easily when the wind blows. Four items are chosen which are 0.75mm/ 1.0mm extruded plastic rods(white coloured) and 0.75mm/ 1.0mm extruded acrylic rods(transparent). I use white rods to create interactive grass.

Prototyping
Prototyping for the project contains PIR sensor, which responds to visitor’s behaviour, and gleams when they walk around the sensor. It is controlled by Arduino. Also, I was supposed to use a physical wind to sway rods. First prototypes’ panel(45cm x45cm) has 25 holes.

Concept Drawing
The above image is a concept drawing. I imagined that visitor walk through grass growing in a forest. There was an intention to design so that the whole view can not be seen when they experience it in the space. I would like them to wander around the space as wandering in the forest. At that time, I proposed rod height is up to 2m.
Design Development
Installation plan drawing At this time, I consider installing not only rods but curtain like. By physical wind, curtain slightly sway and I expect visitors can get different perspective respectively. Machine basically head to be stable. It means machines act as determined. The idea of curtain installing is one option for me since I intend to make accidentalness in the space.

Rods were still jiggly.
Rods swayed than the 2nd testing, but still small vibrating.
Panel is too heavy to move by this. Trying another testing using gear-box.

This is a 500 rod version. There is too much space. It should reconsider how the space is arrabged
