Chair Choir is a product service that creates a shared space for citizens of Rotterdam to make music together. It is the result of a speculative design process with making-centred approach where the project's brief was to speculate and design for citizen engagement of Rotterdam for 2020.
For this project, I worked together with two other designers, Haoyung Chang and Mark Janssen. I was the software designer of the project and I used Arduino and MAX/MSP to realize our design idea. Furthermore, I also contributed to the concept development of the final design.
1. Process
First prototype: decision tool
Testing of Music Maker
Decision maker iteration
Another prototype testing
Testing of decision maker
Soldering
testing of Chair Choir
Coding Chair Choir
At the beginning of each week we created a new speculative design scenario where by the end of the week we designed a prototype and tested it. This kind of an iterative and making-centred approach helped us to think and test every single part of our final design throughly.
2. Final Design

At the end, we presented Chair Choir in an exhibition at TU Delft with the citizens of Rotterdam where the reactions were really positive. Chair Choir is both a chair and a music maker. It can be placed in open door public spaces to create the music of city together.
