Sensing Part 2: Force Sensitive Resistors and Photocells
//description
I wanted to create a visualization that would react to user input in ways that either generated stress or calm, and then correlate these graphic conditions to a desired behavior. I chose a flat-topped hyperbolic paraboloid to simulate a sort of balance board.
When the user successfully balances, they see a calm blue-green orb. As they begin to lose their balance, the orb shrinks and the background becomes a bright red.

I decided to monitor the pressure placed on my wrist when using the mouse. And then visualize it on Processing in the form of a line graph. The setting is simply done by attaching a post-it beneath my mouse, and then tape the force sensing resistor on the post-it where my wrist usually rest on. Then the value read by Arduino is sent through serial port to Processing to draw the graph.

Description:
I stuck the photocell sensor into a stress ball and modified the processing code to make the squeezing power of the hand visualized. In order to improve the accuracy, I set the default value of the received power not zero but a minus number (after several tries) that it can offset the squeezing power from the stress ball itself.

I reproduced a 90's console game with Arduino and Processing. A stogy controller with buttons and a joy stick and a simple design of game in a small screen evoke nostalgia of 90's games. At that time, although the games were simple and coarse, we enjoyed playing them a lot of time.
When you push the joy stick, the red rectangle arises. Your mission is to evade collision with reckless white balls!

Description
I placed the cactus above the Force sensor. It is sensitive enough to detect even light touches to the leaves. Each leaf has a slightly different amount of pressure. I visualized these touches by constructing a L-system depiction of the cactus flowering. The virtual cactus gets more wild the harder one presses. Continually pressing the cactus causes it to dance around.

I actually had a hard time trying to think of something interesting to create with processing and the FSR. (I wanted to make an etch-a-sketch, but I didn't feel well enough to complete that in time. Yeah yeah, excuses.) So I looked through the example code and decided to modify Bouncy Bubbles to look like bubblegum bubbles, with the FSR affecting their descent. They seem to be suspended when pressure is applied, but then they come crashing back down when force is lifted.
