Davin, Esteban, and Mel collaborate on Davin's TEDx talk. Awesomeness happens.

Dependencies are:

• Processing 2.2 (latest version as of 1/21/2015)
• OpenCV 2.4.10 (latest version as of 1/21/2015) - install OpenCV as a library from within Processing
• oscP5 0.9.9 (latest version as of 2/10/2015) - install oscP5 as a library from within Processing

Note that Esteban uses Processing 1.5 because of compatibility with USB analog video capture. Davin and Mel have no problems with 2.2.x.

davinted's Issues

Startup: calibrate to parallelogram (single-corner click)

At startup, the user should be able to skew the plane to a symmetrical trapezoid by clicking on the screen to mark the top left corner of the new plane. Trapezoid will be vertically symmetrical. Bottom of screen will always count as bottom boundary.

Track 4 beach balls

Get XY positions for 4 beach balls (ostensibly spray-painted reflective silver) on the screen.

Output ball count by quadrant: too few balls (0.5Hz - 0) , right # of balls (1.5 - 1) , too many balls (10 - 2)

Output ball position by X-Y values on the skewed plane. If outside the plane, the ball position is the nearest valid input (lock to nearest edge).

Ball position can be scaled from 0-255 as well, to make Esteban happy.

Create max/min brightness calibration function

Output brightness values should be integers between 0-255.

There should be a brightness value calibration function that sets the floor and ceiling values for that range. Values below the floor should output 0; values above the ceiling should output 255. Values in between should be scaled proportionally.

The brightness calibration function could be activated by a mouse-click on that quadrant, and display a countdown on the screen -- I'm flexible here, though.

Cite Squidball in writeup

Open a blank doc for paper writeup, and put notes about Squidball in it. http://movement.nyu.edu/squidball/paper1.html

Implement OSC output

Use http://www.sojamo.de/libraries/oscp5/ to implement OSC output for interface with Davin's audio

Implement 5 second rolling average

Output is jittery; implement 5 second (better yet, easily-customizable) rolling average. Output does not need to start until 5 seconds in.

Use Esteban's camera instead of built-in webcam

Interface with Esteban's IR camera instead of the laptop's hard-coded webcam. This is already in Esteban's code, I just need to merge it in and clean it up.

Output brightness of each (skewed) quadrant

After #5 is implemented, the OSC output needs to be rewritten so the brightness of each skewed quadrant is output.
