This is a really ambitious, interesting project! I'd like to see how it turns out in the end, if you keep going with it. Keep it up!

I am now working on the visuals, this is a priority because:

• I want to make it immediately clear to people that the game "knows" when they move, that they are seen.
• There is quite a high likelihood that in the outdoor setup things will not work as expected. The least I aim to achieve is that the game is a pretty screensaver nonetheless.

So, I would love to have your feedback on the following two methods of visualising the players' motion

A
In this approach I'm trying to detect and draw the contours of passers-by, having these as polygons means I can draw them with funky gradients, but detecting the contours from motion blobs is not always accurate (as you can see when many people walk into view).


B
In this approach I'm using the raw optical flow data (magnitude > some_threshold) to draw a fading history image. It's more precise but allows for less shiny polygon-ness.


If you have any other suggestions, I'd love to hear them, this is a problem I've been stuck on for the longest time now

Maybe you could change the color of the motion flow data according to the area of the screen it's in (like green's in the top-left corner, purple's in the middle, red in the bottom-right, etc)?

I'm not entirely sure how many colors I want to use yet. I could go for full-on rainbow or a more limited palette.

I'm settling on a style like this tho:



It's pretty intense, because I want to make use of the intensity of the big-ass LED screen that the game will be played on.

Whoo! Compiling on Windows using Code::Blocks took me only part of one day. Thank you oF!

Looks pretty interesting. Are you using OpenCV for the image processing in this, or some other library?

I'm using OpenCV extensively yeah, even for parts of the graphics (cv::Mat <3). ofxCv has some truly neat wrappers for a bunch of other functions; combining e.g. the output of OpenCV's Object Detection with a simple rectangle tracker for persistent objects. It all works fairly well out of the box.

We did a pilot/test at Playful Arts Festival, I filmed some of that and made a little edit:

This is awesome.
That was a fun video to watch.
What do you have planned next?

What do you have planned next?

I noticed two things:
- It takes time for players to notice that they are being filmed, but they do really like to strike a pose for the camera.
- They expect to win more than just being on top of the scoreboard.

I have a plan to add a cool feature that will address both of those issues; I'll implement this depending on when the next public showing of the game is.
