We have created ChristmasViewfinder, an diorama with actualized, moving pieces comparing Christmas as it relates to today’s modern, capitalism-fueled society against its religious origins.
We juxtaposed modern Christmas commercials with the religious figures of the well-known nativity scene. Additionally, different parts of the display change every time the viewer pulls the viewfinder lever. This allows us to tell a multitude of narratives about Christmas’ varying religious and capitalist meanings.
In order to implement this diorama, we used an Arduino Leonardo as the main brain to control all the different actuation. We used two relays to control high voltage lines going to Christmas lights and an incandescent bulb (that lights up old projector slides). We used the Arduino’s PWM pins going to MOSFETS to control the LED strips in the ceiling of the diorama. We also used Adafruit’s 12-bit PWM driver to control additional servos and individual LED’s.
The Arduino Leonardo was also used as a USB keyboard to control a Processing sketch on the computer.

We designed a fabric sensor intended for the user to take one-word notes and send said notes as reminders to themselves.
Our primary purpose in creating this sensor was to write reminders on a device without the rigidity found in most devices offering the same service.
What our project actually ended up being was an exploration in soft wearables and sensing.
We discovered that the reason soft wearables are not the first choice of many is because the margin for error is so much smaller when dealing with dynamic material.
We also discovered several key aspects of creating soft touch pads. Most importantly is the overall construction. To sense position, we used three layers of material:
- conductive fabric (grounded)
- a spacing mesh
- a piece of velostat (with 4 connections to measure resistance)
By pressing on the fabric, a connection is made between the conductive fabric and a point on the velostat. The resistance from each measurement point to the point of contact is then measured with an ADC.
We experimented with several conductive fabrics, spacing meshes, and connection orientations. Our process can be found in our previous documentation (linked above).
Also, the xy data from the sensor needs to be linearized. The linearization method depends on the orientation of the connections, but for our final prototype we linearized using the catenery curve (http://forum.arduino.cc/index.php?topic=184285.0).

]]>We wanted to create a soft, fabric sensor that one could interact with to create reminders for later if one doesn’t have paper, pens, notebooks, or ways to record reminders immediately available.
The idea of creating something more wearable and natural than a smartwatch is what first appealed to us. We did a lot of experimentation with various materials, various mesh spacing fabrics, arrangements of connectors, and in particular, our calibration algorithms.

We also played around with Light Blue Bean and got it to talk to a Macbook, but getting an Android phone to control it is another problem entirely.

]]>So our group posed the question, what if we forced two people to work together by communicating through outputs appealing to two different senses?
Collabright bridges two users by allowing one to control sound output in the form of the classic “Happy Birthday” and the other to control visual output in the form of a strip of LED lights. The user whose output is sound controls the song by running a piece of wire down a length of rubber tubing at varying speeds and positions while the user who changes the LEDs controls the lights by running a piece of wire around a color wheel, also composed of rubber tubing.
The idea is that the users can create an experience together that is more powerful than when either one works alone.
The “Solar Bikini” is the work of Brooklyn designer Andrew Schneider, created for the 2006 Tisch School’s Interactive Telecommunications Program Winter Show.
The wearer is capable of charging small electronics, and can even go swimming while wearing it! (Note: do not charge and swim and the same time)
To be fair, I’m pretty sure Schneider intended this more as artistic commentary on technology, but he’s also still offering custom orders.
Unrelated to this work, Schneider is the 2015 OBIE Award winner, and was given five stars by both The New York Times and TimeOut New York.

“Massage Me” is a “wearable massage interface” that turns a back massage into a video game controller.
From their website:
Playing Massage me requires two people, one who wears the jacket to receive the massage and one who massages the person wearing the jacket. Soft flexible buttons are embedded in back of the jacket so that wearing it turns your back into a gamepad. All you need to do is to sit or lay down in front of a video game player and you will be able to enjoy a back massage while the game lasts.
Satomi and Perner-Wilson are not currently taking orders, but you can assemble your own by following their DIY guide.

The “Selfie Hat” by Christian Cowan-Sanluis was developed in collaboration with Acer in order to promote Acer’s Iconia A1-840 tablet.
Regardless of its original intent, the unwieldy, glittery, pink sombrero impressively defies the laws of gravity to support a large tablet fold-out on the brim of the hat.
This hat was first put on display by Cowan-Sanluis in his fashion presentation at London Fashion Week 2014.
Those interested in purchasing one should contact Cowan-Sanluis for a consultation.
