Need a team!

Hi folks,

My name is Olivia and my partner just dropped the TUI class so I don’t have a team any more. My interest is in cross-sensorial perceptions (i.e. “seeing” sounds or “hearing” visuals) in any context. Any teams out there who can use a 3rd person?

Thanks! can email me at

Tangible inputs to intensify “chills”/emotional response in music

hey everyone,

I am a first year PhD at the I School with an interest in augmented public spaces. Owen and I are potentially looking for a third member, ideally with a background in music.

Our current idea involve using tangible inputs to alter specific characteristics of music to intensify their capacity to induce chills/elicit an emotional response. In particular, we are interested in whether some kind of agency on the part of the listener can evoke a more intense emotional experience (since music typically is one-directional, from the composer/musician to the audience).

A simple idea would be to position 3 motion sensors in a darkened, enclosed space, and have each sensor modify a characteristic of the music (likely on an analog dimension). For instance, one sensor would change the relative loudness of the different voices (birdsong vs heavy strings vs. light strings), change the reverberation and atmospheric quality (in an echoing space), or alter the pitch or slow the beat of the music, etc. The quality of the music changes as the listener moves around the room, places his hand out, or if there are multiple participants in the room. Participants can “play” with the music by modifying their position and hand motions within the room.

Here is a piece by Andrew Bird we might start with:

The idea extends some work in a previous biosensors course with John Chuang – archival blog post available here:

Hello! When will the prompt for RR03 be updated? It still says TBD, I believe.

Project partner(s) interested in/tolerant of math education?

Hey! So I’m interested in putting together a project that offers a tangible means of interacting with mathematical representations (a graph, diagram, geometrical object, etc.). A main role for the computing part of this project would be to handle calculations so that users can focus on qualitative patterns and relationships. By backgrounding computation, my hope is that this project would make targeted mathematics concepts an accessible consequence of the designed physical interaction.

A few ideas so far (not wedded to any one, happy to consider more):

  1. An interactive graph where users could bend, move, or rotate a physical object representing a function. The corresponding equation for that function would update in real time. Could maybe be contextualized as a roller-coaster building game.
  2. Mirrored Spirograph (perhaps more aligned with art). Interface is that of a typical Spirograph, but users could choose to have the image reflected along various axes (as through mirrors, but electronically, perhaps in different colors or with different time delays/effects).
  3. A triangular frame with sides that lengthen/shorten and corners that rotate through a variety of angles. By automatically calculating properties of that triangle (area, perimeter, trigonometric functions), users could explore the impact of certain deformations on various properties. For this one, the motivating Object(ive) needs some work…

If any of these ideas sound interesting to you (or if this sounds like an avenue you’d like to think about together), please let me know!


Arduino Resources

Here is a book on getting started with Arduino. If you are looking for additional resources it might be helpful.

resistor value calculator

To find out the resistance value of a resistor, you use the colored bands. There are “resistor color code calculators” online where you enter the band colors and it tells you the resistance.

One such website:


If you try to enter the colored bands backwards, then it either won’t work or it will tell you that you have entered them backwards.

Also, remember that we only gave you a few different resistors in the course lab kit, so if you are getting a resistance value other than that then there might be some mistake – double check that you got the colors right.
