I have a system design question I was hoping u guys could help me with.

So I want to make a display that shows an animated wallpaper. I want to have a camera in the display that will recognize finger gestures and will change the wallpaper accordingly (shuffle to a new one, etc.)
EX: when the current wallpaper is displaying, when the user shows the camera the peace sign, it will switch the current wallpaper to a random wallpaper.

I used tensorflow and the mediapipe hands library to get the finger gesture recognition to work. I used tensorflow, python, and openCV.

Now that the finger gesture recognition is finished, I moved to the animated wallpapers and I made a couple with p5js.

How could I best combine the two? Should I switch from tensorflow in python to tensorflow.js? Or should I find a way to re-do my animated wallpapers in python?

My original plan was having the foundation of the whole system be python. This is so I can have the finger gesture recognition run on the main thread, and have another thread deal with the wallpapers.

Let me know if u guys have any ideas or if I’m not clear. Thanks!!!

    Tensorflow.js is kinda garbage.

    Why not use some IPC and send messages between the the wallpaper process and the visual detection process? :D

    @rantydev I was hoping that I could do this without Tensorflow.js lol I'll definitely check out IPC. So my thought now is to have the recognition program run on the main thread, and then have a separate thread where I have a local web server (written in python) to handle the p5js stuff. Then, I can use IPC to pass data from the recognition thread to the web server thread

    đź‘Ť I'd probably go with different processes alltogether: run node in one process, python in the other, and use sockets for IPC

    ..but that's just because I like IPC :)

    @rantydev Ohh i understand. Im trying that approach right now. I just have to figure out the server aspect. I have an html file with inline js for each wallpaper. I have to figure out how to change the html file being served, when the node server gets the data from the IPC connection. Then, i have to figure out how to refresh the page on the browser to reflect the change of wallpaper
