Ask HN: Gesture Recognition for JavaScript?

I print out cards on my inkjet printer and assemble between 3 to 40 on the wall. The back of each card has a description of what's on the front of the card and a QR code. I call these "three sided cards" because they have a front, a back, and a web side linked from the QR code.

To make the backs visible the "constellation" has a digital twin which can be accessed by scanning a QR code that is installed next to it.

The current "web side" is not so great but I am thinking about making it better with a WebGL-based back end.

I like the game Paper Mario Sticker Star where you can peel things with the touch screen on the Nintendo 3DS. It would be natural in my interface for people to be able to peel an image off the wall on their phone to see the back side. Is there a good library for recognizing the kind of touch gesture in Javascript?
