When analyzing the web contents of SNCF, I made this realtime tag cloud charter for Twitter. It’s a lot of fun.

The Copenhagen Wheel: Data Viz Journal III

December 20, 2009

Presentation of the Copenhagen Wheel project at UN Climate Summit for Mayors in December was a huge success. I would like to post a few videos here which is related to my work:

The idea was that pollutant information collected by the sensors embedded in wheels were transmitted to our server through smart phones. A web interface, accessible with both pc and phones, showed pollutant distribution in real time. One could browse his own data, keep a record of his contribution to a greener city, challenge with friends, and get route suggestions according to pollution level. The city management could keep an eye on the city and react to dangerous level of pollutants right away. The complete and high-definition record of pollutant maps could also cross-reference with land use, weather, transportation etc. in urban research and in long term, support policy decisions.

Customizable Production II: Tree

December 20, 2009

This starts from a project for 4.510: Materializing Design by Prof. Larry Sass.

We made a web applet which support making customizable tree-like canopy for coffee shops. User can access to our website, build his own design in friendly 3d interface, take the generated CAD file to any nearby CNC machine and cut the parts from 3/4” plywood sheets. Following online instructions, he can assemble the parts with a few untrained men. Everything is finished locally.

We have tested the system with prototypes in various scales. The latest ones are 1:6 models made from 1/8” masonite with lasercutter. Metal pieces are cut with waterjet and hand bended. Right now the shape and angle between parts are chosen to simplify design and assembly. Next version in our plan will work with advanced machines and materials to support more flexible and fluid surface designs.

Representations and Processes

November 24, 2009

This is an assignment for 4.580: Inquiry into Computation and Design by Prof. Terry Knight. We were asked to design an extension for Louis Kahn’s Richards Medical Center, and look into the relationship between process and representation.

We translated the plan into two types of components: square units and connections. We then built a program that automatically generate connections from any units layout. The appearance of a connection depended on the sizes and distance of two neighboring units. We believed the program somewhat reflected the underlying logic in Kahn’s original design, and could accommodate most possible extending scheme.


Ironically, in class, most designs submitted by the other groups could not be drawn by our program. Of course we could indicate that they do not follow the ‘true’ grammar of the original plan. After all it is impossible for such a program to accommodate any design intention. Processes are limited by the way of representation we choose. Unless we change the mechanism that machines learn and induce, they can only do things that we understand before them.

The Copenhagen Wheel: Data Viz Journal I

October 9, 2009

The goal of the Copenhagen Wheel project is to create a smart, responsive and elegant emblem for urban mobility. It transforms ordinary bicycles quickly into hybrid e-bikes that also function as mobile sensing units. It allows you to capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost. It also connect your bike to a larger community through smartphone to map pollution levels, traffic congestion, and road conditions in real-time.

I was recruited to visualize the data collected into interactive graphics. In the first review I set myself 3 goals: i) visual impact; ii) insightful interpretation; iii) support for easy reading & decision making.
Embedding sensors in bicycle wheels has obvious advantages that make the visualization interesting, such as mobility and realtime networking. However in current phase of the project, we had no prototypes finished, and could only expect around 15 sensors sent out before the final presentation. That data is too sparse on a city of 4 square km. Moreover, since we have loose control of where the riders go, it is almost impossible to get a filled map at a random time spot.

My first solution was what I called ‘merged time’: users saw data from different time on a merged map, but could also tell which are old and which are new. Data left a fading trace after them. Here is the first demonstration video I made for the concept.

the Symbolic, the Visual, the Recursive

October 7, 2009

This is an assignment from 4.580:Inquiry into Computation and Design by Prof. Terry Knight. We were supposed to parse a design into rules that could be passed on and used to regenerate it.

We took Le Corbusier’s plan of Maison Citrohan (1927). It was crucial to which detail one chose to represent the design. We realized that by just extracting out elements from the plans, shape grammar would be very symbolic and become a shopping catalog. The recursive function and flexibility was a must in order to develop a true design tool. We ended up with a Corb automator with recursive functions but also one symbolic architecture element introduced (the stair).

In class discussion it was left an open question whether the nature of architecture is symbolic, but it seemed unlikely that limited rules can describe everything in design.
