Electronic Spirit Board

I tried to make an electronic spirit board that multi-player could play on their touch screen at the same time by calculating their center point. I made several pieces but when I tried to put them together. I failed. I will keep working on that this week.

First, I build a server using node.js. You can see that I can draw in several windows in my localhost at the same time.

But when I tried to use Heroku┬áto make it available on Web, it could draw but failed to show the drawing from other windows…

 

Finally, I wrote a sketch to calculate the center point of multi-touch.
