UX, Installation - 2017



Attending various local music events, I noticed coordinators had trouble getting their audience members to engage online. This presented a missed opportunity to use crowds to build social media presence during performances.


Chirp encourages audience members to engage with music events by combining social media with sound visualization. Using Arduino, Processing, and Twitter, the interactive installation projects live tweets on stage using an event hashtag. Through a microphone, tweets are modulated in real-time by frequency levels in the room. In doing so, a social media presence is built while emphasizing the energy of a performance.


The first step was getting Arduino to output the microphone frequency levels into the serial monitor. I searched through various FHT and FFT libraries, eventually getting the Arduino FHT library to work. It was convenient that the library used FHT, as it works half as much processing power and half as much memory as an FFT.

After a Google search on Twitter and Processing, I found out about Twitter4j. It's a library that helps bring in tweets to Processing using a keyword search.

As for typography in Processing, I stumbled upon the book Type + Code: Processing For Designers by Yeohyun Ahn and Viviana Cordova. The book provides a range of typographic Processing examples, from beginner to advanced. With further reading I found the library Geomerative, used to create extensive 2D generative geometry with .TTF and .SVG fonts.
