Draw shapes for input

Hi Guys,

Today's google doodle looks super fun. You draw shapes for input. Is this possible to replicate in C2?

How??

What's the best example of an implementation on this forum?

some info i found:

I want an implementation that works on all sorts of shapes- anywhere on the screen.

Not just square vs circle, but also heart, flash, etc etc

I wonder if we can come up with a solution that uses a neural network training with

plugin-rex-ann-artificial-neural-network_t109290

used with

but not even sure where to start. Basically I want to tach the software how a gesture looks like by inputting it a number of times.

I assume that is how google did it

It's not that hard to detect simple movement.

On touch start set start variables to touch xy

On touch end set end variables to touch xy

If start xy is higher than end xy, then it's a downward slope, etc.

For something more complex such as multiple swipes in a single touch, try Podes gesture recognition plug.

I posted some questions there:
