1. 2nd Iteration of My Prototype

• Goal of the project and/or desired interaction
  I hope to be able to press on a force pressure sensor to activate the camera for the face detection to track my motion and then turn the camera off by pressing on another force pressure.
• Quick description of assembly and list of core components
  – Arduino x1
  – Small Bread board x1
  – Force pressure sensors x2
  – Servo motor x2
  – Jumper wires
  – Resistors 220ohm x2
• How it works
  When you stand in front of the camera, it will not work but when you press on 1st pressure sensor, the camera will start tracking your motion and turn towards wherever you are moving. You can turn the camera off by pressing on the 2nd pressure button.
• Any problems you encountered and/or solved
  I have encountered many problems with the code where the code tends to be stuck in an IF statement and another problem I still face is that the code only runs once. After running once, it won’t activate again unless I restart the Arduino and processing sketch again. I still haven’t figured out what is the problem since the code looks all correct.

2.  Your playtesting plan and desired feedback

Who will you playtest with?
I will playtest with my fellow peers from Design & Technology program and possibly some other same age peers from different programs in Parsons.

How will you get their consent?
I will ask them if they are willing to test out a quick interaction and give me some feedback.

What feedback do you want?
I want the interaction of my model doll dog to be intuitive so I know where to exactly design my pressure sensor on my model dog.

What questions will you ask?
What is the first intuitive response of placing your hand at (on my model doll dog)?
Where do you think you can press to activate music?

What information do they need to know before starting?
I will give them a basic overview of my concept.

How much will you help them during the test?
Aside from trying to give them a basic overview, I will try to let them figure out themselves. If they really need help, I will give them hints.

How will you debrief them?
I will let them know what I’m really testing orally and ask them if they have any questions.

“Nemore” is a garden, consiting of 36 bendable graphite poles. “Nemore” senses the visitor. Each pole has a behavior and reacts to it’s neighbours only: and to the visitor, of course – the visitor acts an “alien neighbour”. We are interested in the question: Does a system arise from the poles behaviour, that we (the observers and the visitor) perceive as angst, curiosity, nervousness, etc.? Each pole has a distinct sound, that builds up a chord, fluctuating in resonance with the movement of the poles.

Max Kickinger describes the setup : “The poles are driven by two servo motors – one rotates the pole, the other one pulls up a coil with a fishing line attached, bending the pole. The garden is controlled by six arduino mega, a computer runs vvvv for the server application and pd for the sound. Sound works as simple additive synthesis made out of 36 sine oscillators. No sound is played, when the garden is in the “center-position” – only the irritation of the poles generates a modulation of pitch and amplitude : the wider the bending of the pole – the louder the according oscillator will sound. Pitch works in either way – up and down.

This art piece contains physical computing mechanism using movement sensor (ultrasonic? thermal detector?) to make servo motors rotate and bend the poles. In addition, each pole has a oscillator generating sounds according to the poles are bending. I am interested in sound and how its resonance affects to the space according to human interaction. Also I have an idea that “awakening our hearing sensor,” which is creating a new communication tool using variety of pitches and rhythms instead of language we are too accustomed to as much as we can easily hide or deceive our authentic feelings. I assume this “Nemore” project can be a brilliant technical precedence for my future project.

This project is six years old, but I only just saw it for the first time. Still feels relevant. I clicked for the catchy name. I stayed for the hardware talk. Once I heard “video experimenter shield,” I was hooked. My knowledge of PComp is so limited, that this whole concept of shields is new to me.

This example showcases a video shield made by Nootropic Design. The shield allows you to feed the video signal from cable box to Arduino, which parses the closed captioning transcript for keywords. When a keyword is detected, the Arduino mutes the TV for 30 seconds via an IR sensor.

As Matt Richardson explains in the video, a world of possibility opens up when you turn your Arduino into an infrared remote control. It’s such a simple mechanism, but when used as a form of censorship or commentary, it has some real potential. Here it facilitated a conversation between cable box, Arduino, and TV, and between passive consumer/active producer by extension.

I also like that this project is explained well in the video. I feel like I could replicate this and then tweak with my own ideas.
